Total and Attuned Multiple Autonomy Support and the Social Development of Early Adolescents

The effects of Multiple Autonomy Support (MAS), meaning the autonomy support provided by two or more sources, is an overlooked topic in social development literature. The aim of this study is to understand how two types of MAS, Total Multiple Autonomy Support (TMAS) and Multiple Autonomy Support Attunement (MASA), are related to early adolescents’ social development indicators (prosocial behavior, self-regulation, antisocial behavior, alcohol use, and 1-year substance use intention). TMAS pertains to the general amount of autonomy support perceived by a MAS recipient, irrespectively of each provider’s contribution to that score. MASA refers to the interindividual patterns of perceived coordination among MAS providers, based on each provider’s autonomy scores. The participants were 818 early adolescent Portuguese (M = 12.15; SD = .81; 54.2% girls) surveyed in a cross-sectional exploratory study about MAS provided by parents, teachers, and mentors. Descriptive analyses revealed levels of low (n = 81; 10.00%), moderate (n = 432; 52.82%), and high (n = 302; 36.91%) TMAS. A k-cluster analysis revealed four MASA groups: low attuned MAS (n = 128; 15.65), misattuned MAS/low attuned parent autonomy support (n = 225; 27.51%), misattuned MAS/low attuned teacher autonomy support (n = 177; 21.64%), and high attuned MAS (n = 288; 32.21%). Ordinal regressions show that, after controlling for age, a pattern of high attuned MAS predicts better prospects of prosocial behavior and self-regulation, as opposed to high levels of TMAS. In addition, MASA involving low teacher autonomy support predicts the worst results on the selected indicators of social development.


Introduction
This study aims to show how two different forms of Multiple Autonomy Support (MAS), Total Multiple Autonomy Support (TMAS) and Multiple Autonomy Support Attunement (MASA), are associated with early adolescents' social development indicators (prosocial behavior, self-regulation, antisocial behavior, alcohol use, and 1-year substance use intention). Autonomy support corresponds to the set of interpersonal sentiments and behaviors provided in order to promote the identification, nurturance, and development of someone else's organismic needs of choice, self-regulation, and inner motivational resources (Ryan and Deci 1987;Reeve 2009). Multiple autonomy support (MAS) involves the satisfaction of autonomy needs by two or more autonomy support providers. MAS measurement may consist of comparing the relative influence of each source of autonomy support in a given outcome (Rueger et al. 2010). However, MAS may also be measured according to two types of shared effects. TMAS refers to the general amount of autonomy support perceived by a MAS recipient, irrespectively of each provider's contribution to that score. MASA pertains to the interindividual differences on the degree of perceived coordination among MAS providers, based on each provider's autonomy scores, generating different patterns of coordination: low attuned MAS (whenever all MAS providers deliver low levels of autonomy support), misattuned MAS (when some MAS providers deliver different levels of autonomy support), and high attuned MAS (when all autonomy support providers deliver high levels of MAS) (Simões and Simones 2017).
Three main reasons sustain a comparison of TMAS and MASA relationships with social development indicators. First, MAS, seemingly to multiple social support effects in its most different dimensions (e.g. emotional support), has been conceptually delimited as involving only the analysis of the relative or unique influence of each social support source (Rueger et al. 2010). The analysis of MAS shared effects, whether they are conceptualized as a general amount of autonomy support or in the form of coordination between distinct support providers, have been kept outside the boundaries of multiple social support literature, including the social development field of inquiry. As a result, the analysis of such types of effects has received little to no attention in the literature. A recent systematic literature review (Simões and Calheiros 2017) further upholds this idea: among 250 reports, only two documented total social support effects over developmental outcomes, while one depicted social support attunement effects on identical outcomes. More importantly, none of the identified reports focused on TMAS or MASA effects.
Another reason that justifies an analysis of MAS total and attuned associations with social development indicators is the significant reconfiguration of social relationships in early adolescence (Rudasill et al. 2010). In this period, parents become less pivotal, though they are kept as significant others "in reserve" (Cotterell 2007), peers assume greater centrality, despite friendships remaining fluid until early adulthood (Fletcher et al. 2011), and bonding with non-familial significant adults becomes more relevant (Schwartz et al. 2013). The transformations in the structure of early adolescents' social relationships have implications for MAS. Early teenagers' access to conflicting perspectives regarding moral and social issues, their struggle to establish a personal domain of decision-making (Smetana and Daddis 2011), as well as a decrease in their perceived parental legitimacy  shape perceived MAS.
A contrast between MAS total and attuned effects over social developmental indicators in early adolescence seems warranted as well, because it focuses on the pivotal discussion of quantity vs. quality of supportive behaviors and relationships and their effects, which remains a candent issue in social development literature (Guay et al. 2013).
A comparison of TMAS and MASA influences on social development requires a clear definition of autonomy support. Autonomy support encompasses interpersonal sentiments and behaviors delivered in order to promote the identification, nurturance, and development of someone else's intrinsic needs of choice, self-regulation, and inner motivational resources (Ryan and Deci 1987;Reeve 2009). Autonomy support is opposed to control, which is based on the restriction of opportunities and informative feedback, allowing self-initiated actions and choices (Ryan and Deci 1987). Socio-cognitive perspectives have further divided control into physical, psychological, and behavioral or monitoring. Physical control encompasses the use of physical force: yelling, grabbing, pushing, hitting, using tangible expressions of anger, and using physical threats (Akcinar and Baydar 2014). Psychological control includes aspects such as intrusiveness, guilt induction, and love withdrawal. Behavioral control involves rules and the definition of expectations or restrictions that come to define interpersonal exchanges (Smetana and Daddis 2011). Behavioral control corresponds, in part, to contextual demands and limits or giving directions, which are more restrictive-driven, while it also involves expressing expectancies or providing feedback, which are more autonomydriven (Reeve 2009).
Autonomy support and control rely on a conceptual continuum, which is universal across developmental stages, contexts, and cultures. Some studies have, nonetheless, disputed the idea of a universal opposition between autonomy support and control, because relationships such as parenting render a more complex combination of autonomy support and control strategies (Calafat et al. 2014). Others have contested the autonomy support continuum from a cultural standpoint, arguing that collectivist cultures, with greater levels of power distance (Hofstede 2011) or societies with fragile democracies tend to value control compared to individualistic cultures and democratic-experienced societies (Akcinar and Baydar 2014).
Following the conceptual definition of autonomy support, MAS literature comprehends three possible avenues, which correspond to three distinct measurement approaches. The first approach complies with prior general definitions of multiple social support analysis. This involves the relative or unique influence of each source of autonomy support on a given outcome, from the autonomy support recipient standpoint (Rueger et al. 2010). According to this perspective, the goal is to understand the effect of each autonomy support provider above and beyond the influence of other sources. A more recent perspective sustains, however, that multiple social support in all its dimensions, including MAS, must encompass the analysis of its shared effects, in order to capture the complexity of support provision (Simões and Simones 2017). From this standpoint, MAS collective shared effects may be divided in two types. TMAS includes the impact of the MAS provided by all sources, by adding their contributions to a composite measure of autonomy support. This composite measure can then be used as a general predictor of a given outcome or further collapsed in different levels of total MAS (e.g. low, intermediate, and high), to analyze how different amounts of general MAS affect an outcome of interest.
In turn, MASA pertains to the interindividual differences on the degree of perceived coordination among MAS providers, based on each provider's autonomy scores. MASA is based on the concept of attunement as a sense of unity or communion in relationships that goes beyond empathy (Erskine 1998). This attunement definition has been applied to dyadic relationships in contexts such as psychotherapy (Erskine 1998), mentoring (Pryce 2012), or attachment theory (Cohen 2015) and has recently been extended to social support literature to describe the degree of perceived coordination between multiple supportive relationships, irrespectively of the form (perceived or received) or dimension (e.g. autonomy support) of social support. The MASA degree of perceived coordination among MAS providers may generate at least three patterns of coordination. Low attuned MAS involves the provision of low levels of autonomy support from all sources. In turn, misattuned MAS occurs when MAS providers deliver different levels of autonomy support. Finally, high attuned MAS is achieved when all autonomy support providers deliver high levels of MAS (Simões and Simones 2017). These patterns, namely the number of misattuned MAS patterns, may vary depending on some factors, such as the number of regarded autonomy support providers or the research goal.
Autonomy support research has mostly focused on the unique effects associated with each autonomy source of support. Such an option is evident in adolescents' social development literature, regarding sources such as parents, teachers, or natural mentors. Mixed trends are obvious in this field of inquiry.
Voluntary action intended to benefit others or prosocial behavior (Yoo et al. 2013) has been associated with autonomy support provision. Parental autonomy support induces greater incidence of altruistic helping behavior among early adults (Roth 2008). Parental control, however, also predicts greater prosociality among early adolescents, when it is associated with parent-children balanced connectedness (Yoo et al. 2013). In turn, teacher autonomy support promotes greater prosocial orientation among high school students (Roth et al. 2011), while natural mentoring autonomy support predicts early adolescents' higher rates of prosocial behavior (Lenzi et al. 2012).
Autonomy support has been associated with selfregulation abilities as well. Self-regulation entails flexible regulation of cognition (e.g. the ability to set goals and plan actions), emotions (e.g. adjusting affective states), and behaviors (e.g. replacement of impulsive response by a normative behavior) (Bridgett et al. 2015). Parental (Roth 2008) as well as teacher (Schuitema et al. 2016;Vansteenkiste et al. 2012) autonomy support practices contribute, respectively, to adolescents' development of more mature forms of self-regulation and to boost specific selfregulation abilities, such as deep-learning strategies and persistence or the ability to delay gratification. Programmed mentoring has been linked to greater self-regulation abilities as well, such as improved classroom effort (Schwartz et al. 2011).
The involvement in social rule breaking, also known as antisocial behavior (Cotterell 2007), has been connected to autonomy supportive practices too. Parental autonomy support has been found to be effective in deterring adolescents' antisocial behavior, both concurrently and across lifespan (Dias et al. 2012). In contrast, greater psychological control has been found to induce adolescents' lower anger regulation that, in turn, leads to more recurrent delinquent behavior (Cui et al. 2014); while behavioral control, in terms of prohibition or disapproval of friends, leads to an increment of contacts with deviant peers and, as a consequence, to greater recurrence of deviant behaviors (Keijsers et al. 2012). Other evidence points out, nonetheless, that greater parental control can predict lower antisocial behavior rates (e.g. Barber et al. 2012). Autonomy supportive teachers, in turn, seem to contribute to the reduction of adolescents' levels of verbal and physical aggression (Pikó and Pinczés 2015) truancy (Vaansteenkiste et al. 2012), and involvement in bullying (Roth et al. 2011). Moreover, natural mentoring predicts less problematic behaviors (gang membership, hurting others in physical fights, risk taking) (DuBois and Silverthorn 2005), and longitudinal criminal involvement in the transition to adulthood (Schwartz et al. 2013).
Finally, substance use is also seen as an indicator of social development, as it entails smoking, drinking, and drug use rates among a given group (Perra et al. 2012). In the context of parenting, substance use has been studied in connection with parental autonomy restriction. Some studies sustain that greater parental control reduces the risk of substance use, especially among boys (Becoña et al. 2013) and older adolescents (Piko and Balázs 2012). Others (e.g. Calafat et al. 2014) have depicted that both authorized parenting (which includes aspects of control) and indulgent parenting were associated with lower levels of substance use. However, in some reports (e.g. Kiesner et al. 2010), lower levels of behavioral control were associated with greater substance use. In addition, High quality teacherstudent relationships (Perra et al. 2012) as well as natural mentoring (Schwartz et al. 2013) contribute to a reduction of the use of alcohol use, tobacco, and cannabis.
The reviewed literature demonstrates that the impact of autonomy support is mostly contradictory, with a few exceptions (e.g. teachers' autonomy support on self-regulatory aspects). An important remark is that these mixed findings tend to be associated with two dispositional factors: gender and age. In the case of gender, boys tend to elicit more recurrent and sometimes more restrictive control by adults, both in familial and educational settings (Becoña et al. 2013;Reeve 2009;Smetana and Daddis 2011). Age is another moderator of autonomy support effects. Although autonomy supportive practices may be beneficial from childhood to early adulthood (Reeve 2009), adolescents' perceived legitimacy of adults' controlling behaviors , as well as the number of areas where legitimate autonomy support intervention by adults is accepted, especially from parents (Smetana and Daddis 2011) declines throughout adolescence.
The present study intends to explore how MAS collective effects, TMAS and MASA, influence five early adolescents' social development indicators: prosocial behavior, self-regulation, antisocial behavior, alcohol use, and 1-year substance use intention. Given that the comparison between TMAS and MASA effects is a novel approach, and that the literature of autonomy support unique effects has provided mixed trends, this study is exploratory in nature; thus, no hypotheses were formulated.

Method Participants
A cohort of seventh graders from 19 public schools was invited to participate in the study, in a Portuguese intermediate region according to international standards (between 106 and 201 inhabitants by squared kilometer) (Organization for Cooperation and Development 2011). From a potential group of 1836 adolescents from 16 schools agreeing to collaborate, 1 283 participated in this study (69.88%). Out of these, 818 adolescents (63.75%) aged 12-14 years old (M = 12.15; SD = 0.81; 54.2% girls) were included because they identified a key parental and teaching figure deemed as the most relevant regarding behavioral regulation issues, as well as a natural mentor in their lives that they had known for more than 1 year. From the remaining participants, 419 (32.66%) did not identify a mentor, and 46 (3.59%) were aged 15 or above and were, thus, excluded. The participants were equivalent to the group of those who were intentionally excluded due to gender, χ 2 = (1, 1218) = 2.25, p = .13, and age, t = (1, 1282) = .09, p = .78.
With regard to the professional status of the participants' fathers, and according to the Portuguese Classification of Occupations (Instituto Nacional de Estatística 2010), 34.10% were non-specialized workers, 19.93% worked in services and sales, 18.22% were specialized workers, 10.51% were middle or higher-level staff, 7.58% were unemployed, 1.47% were administrative staff, 1.34% were military and 1.10% were retired; 5.75% of the participants did not report their fathers' professional situation. Concomitantly, 39.00% of their mothers were non-specialized workers, 25.55% worked in services and sales, 15.53% were middle or higher-level staff, 7.33% were administrative staff, 5.62% were unemployed, 2.93% were specialized workers, and .37% were retired; 3.66% of the participants did not report their mothers' professional situation.

Procedures
This study was approved by the Ethics Committee of the University Institute of Lisbon and by the Department of Education of the region where the research took place. All schools of that region were invited to participate. After parental informed consent was obtained, a collective administration of the study's protocol was conducted by class, in the classroom. Data collection involved explanation of research goals, asking the participants for their consent to participate, and reading the protocol instructions. The participants had 60 min to complete the survey. Data collection occurred in November and December of 2015.

Prosocial Behavior
Prosocial behavior was measured using the Portuguese version (Simões and Calheiros 2016) of the Prosocial Tendencies Measure-Revised (PTM-R) (Carlo et al. 2003). This questionnaire encompasses 21 items divided into six subscales. Each subscale depicts a form of prosocial behavior: altruism (four reverse coded items; sample item: "I feel that if I help someone, they should help me in the future"); public (three items; sample item: "I can help others best when people are watching me"); emotional (five items; sample item: "I tend to help others especially when they are really emotional"); compliance (two items; sample item: "I never wait to help others when they ask for it"); anonymous (four items; sample item: "I prefer to help others without anyone knowing") and dire (three items; sample item: "I usually help others when they are very upset"). Response options range from 1 (does not describe me at all) to 5 (describes me greatly). Reliability scores for the original subscales of the PTM-R range from α = .62 (compliance) to α = .84 (emotional) (Carlo et al. 2003), while in the Portuguese version these scores range from a minimally acceptable internal consistency value for dire subscale (α = .67) to an adequate rate for the anonymous subscale (α = .78) (Simões and Calheiros 2016). In this study, the PTM-R was used as a whole measure of prosociality, showing an adequate reliability score (α = .83).

Self-Regulation
The participants' self-regulation was assessed using the Portuguese version (Motta et al. 2017) of the Abbreviated Dysregulation Inventory (ADI) (Mezzich et al. 2001). This instrument is organized in three subscales: cognitive dysregulation (10 reverse coded items; sample item: "I develop a plan for all my important goals"), affective dysregulation (10 items; sample item: "When I am angry I lose control over my actions"), and behavioral dysregulation (10 items; sample item: "I get into arguments when people disagree with me"). Ratings range from 0 (never true) to 3 (always true).
Higher rates on affective and behavioral dysregulation subscales indicate lower levels of self-regulation. Conversely, higher rates on cognitive dysregulation subscales mean higher rates of cognitive self-regulation. Therefore, the original codification of the behavioral and affective subscales was reversed in order to reflect the participants' self-regulation levels, as well as to facilitate the interpretation of results according to this conceptualization. Reliability scores for the original subscales of the ADI range from α = .63 (cognitive dysregulation) to α = .85 (affective dysregulation) (Mezzich et al. 2001). Reliability scores for its Portuguese version vary from α = .84 (affective dysregulation) to α = .86 (cognitive dysregulation) (Motta et al. 2017). In this study, this instrument was used as a total measure of self-regulation, with a reliability score of α = .83.

Antisocial Behavior
Antisocial behavior was assessed using the Portuguese version (Fonseca and Monteiro 1999) of the Antisocial Behavior Subscale of the Youth Self-Report (YSR) (Achenbach and Rescorla 2004). This subscale includes 15 items covering a wide range of antisocial behaviors, from minor rule breaking such as swearing (sample item: I use bad words or improper language) to serious violation of social norms, such as stealing (sample item: I steal things in school). Response options range from 0 (not true) to 2 (true most of the time). The reliability score for the original Antisocial Subscale of the YSR is adequate (α = .81), similarly to the reliability of the Portuguese version (α = .76) (Fonseca and Monteiro 1999). In this study, the reliability score for this subscale was acceptable (α = .71).

Alcohol Use
The alcohol use subscale of the Health Behavior in School-Age Children (HMSC) (Currie et al. 2001) is part of an international questionnaire developed to produce bi-annual reports on children and youth health indicators. This subscale includes three items that measure beer, wine, and distilled drinks use (sample item: How often do you drink beer?). Ratings range from 1 (daily) to 5 (never), with higher ratings depicting lower rates of alcohol use. In this study, the original codification of these items was reversed to properly reflect the participants' alcohol use. This questionnaire has not been used for the Portuguese population as a single alcohol use factor; nevertheless, in this study, reliability rates for its use as a single factor were adequate (α = .75).

One-Year Substance Use Intention
The 1-year substance use intention was assessed with the Intention to Use Scale (IUS) (Jackson 2002). The questionnaire is composed of four items measuring the one-year intention to use alcohol, tobacco, marijuana, or other illegal substances (sample item: Do you think that in 1 year from now you will be smoking cigarettes?). Ratings range from 1 (Sure I will) to 4 (Sure I will not). The reliability scores for the original instrument are not available. In this study, the reliability score was acceptable (α = .70).

Autonomy Support
Autonomy support was measured using a modified version of the autonomy subscale of the Portuguese version (Sousa et al. 2012) of the Basic Needs Satisfaction in General Scale (BNSGS) (La Guardia et al. 2000). The subscale encompasses five items covering autonomy features such as feeling free to express individual opinions, being provided with choices, or having personal feelings regarded by others (sample item: With my father/mother (or teacher or mentor) I feel free to express my feelings). Ratings range from 1 (never) to 5 (always). Items were slightly reworded to enable the participants to assess AS within each of the accounted relationships, instead of expressing their sense of AS in general. However, the items were identical for all of the assessed relationships. Confirmatory factor analysis sustained that a three-factor solution of correlated factors (parent, teacher, and mentor autonomy support, and was the most appropriate compared to a one-or two-factor solution, χ2 (87, 558) = 8.34, p < .001, CFI = .87, RMSEA = .063, SRMR = .06. According to SDT's AS continuum, lower total rates depict relationship control perceptions, while higher rates indicate autonomy supportive relationship perceptions.

Data Analyses
Cut-off points were set for moderate low, moderate, and high TMAS, considering percentiles intervals 25-49, 50-74, and ≤75 respectively for the distribution of total autonomy scores. Low scores (<25 points) were not found for TMAS. A k-means cluster analysis was conducted to explore different patterns of MASA among the participants. K-means cluster analysis is recommended when research goals are exploratory and the study involves a large number of observations, as is the case (Johnson and Wichern 2002). K-means cluster analyses were followed by one-way ANOVA post-hoc tests, using Bonferroni test, in order to verify mean differences between each cluster regarding parental, teacher, and mentor autonomy support, for three, four, and five-cluster solutions. This procedure was intended to validate the best cluster solution. TMAS and MASA group differences were controlled for gender and age. Afterwards, means and standard deviations were calculated for all groups of participants according to TMAS and MASA classification.
Multivariate analysis of variance (MANOVA) was tested, setting levels of TMAS and patterns of MASA attunement as factors and the indicators of adherence to social norms as criteria variables, given that some of the criteria variables presented moderate correlations. However, the principle of homogeneity of variances was violated in each of the examined solutions (TMAS and MASA entered in the model separately or together). Thus, independent effects were examined through a series of separate univariate variance analyses (ANOVA) with each of the indicators of adherence to social norms set as criteria variables and the levels of TMAS and clusters of MASA set as factors. Posthoc tests were conducted to estimate mean differences and confidence intervals using the Tukey test. Given that for self-regulation across both factors and 1-year substance use across different MASA patterns normality was not upheld, in these cases confidence intervals were calculated using the Games Howell test. Finally, separate regressions for total AS and AS attunement were conducted for each of the criteria variables, controlling for age effects. This analytical approach enabled control for age effects, as well as the comparison between a reference category of total effects and attuned effects that delivered worse outcomes and the remaining categories of total and attuned effects, according to multiple mean comparisons. All analyses were made using SPSS 23.0.

Patterns of Total Multiple Autonomy Support and Multiple Autonomy Support Attunement
After running general descriptive statistics (means, standard deviations, and correlations) for all variables (Table 1), patterns of TMAS and MASA were set. Levels of low (n = 81; 26-42 points), moderate (n = 432; 43-59 points), and high total AS (n = 304; 60-75 points) were applied according to the selected cut-off criteria.
According to k-means method, followed by a cluster validation using one-way ANOVA post-hoc tests, a fourcluster solution seemed the most successful in maximizing differences between cluster centers and parental, teacher, and mentor autonomy support means; as well as in providing the most interpretable solution. Table 2 provides the results for between cluster center differences, which were statistically significant (p < 0.001) for all the examined solutions. However, follow-up one-way ANOVA tests depicted statistically non-significant differences between cluster one and two regarding teachers autonomy support (p = 1.00) and between clusters two and three regarding mentors autonomy support mean rates (p = 0.36) for a three-cluster solution; statistically non-significant differences between clusters one and four, regarding teachers autonomy support mean rates (p = .99) for a four-cluster solution; and finally statistically non-significant differences between clusters one and two and clusters three and four, regarding parental autonomy support mean rates (p = 1.00), and statistically non-significant differences between clusters one and five regarding mentors autonomy support mean rates (p = 1.00), for a five-cluster solution. Thus, a fourcluster solution achieved greater mean differentiation between autonomy support variables. Cluster 1 was named low attuned MAS (n = 128; 15.65% of the participants).  Table 3 depicts descriptive statistics for all variables by TMAS and MASA groups.

Mean Comparisons Between Levels of Total Multiple Autonomy Support and Multiple Autonomy Support Attunement
Multiple mean comparisons for TMAS presented in Table 4 revealed that high levels of TMAS presented significantly higher mean rates for prosocial behavior compared to moderate and low levels of TMAS (p < .001), similarly to moderate levels of TMAS compared to low levels of TMAS (p < .001). High levels of total AS presented significantly higher mean rates for self-regulation compared to moderate and low levels of TMAS as well (p < .001), but significant differences were not found between moderate and low levels of TMAS. Mean rates at high levels of total AS did not differ from mean rates at moderate and low levels of TMAS across negative indicators of adherence to social norms.
Multiple mean comparisons for MASA presented in Table 5 showed that mean rates of participants' prosocial behavior showing high attuned MAS were significantly higher compared to misattuned MAS/low teacher autonomy support (p < .001), misattuned MAS/low parent autonomy support (p < .05), and low attuned MAS (p < .001). This was similar to misattuned MAS/low parent autonomy support compared to low attuned MAS (p < .001). Mean rates of participants' self-regulation showing high attuned MAS were significantly higher compared to misattuned MAS/low teacher autonomy support (p < .001), misattuned MAS/low parent autonomy support (p < .01), and low attuned MAS (p < .001) as well. Mean rates of participants' antisocial behavior integrated in the high attuned MAS group were meaningfully lower compared to mean rates of the misattuned MAS/low teacher autonomy support (p < .001). In addition, misattuned MAS/low teacher autonomy support pattern denoted significantly higher antisocial behavior means compared to misattuned MAS/low parent autonomy support (p < .001) and low atunned AS (p < .05).

Discussion
The aim of this study was to understand how two different forms of MAS, TMAS and MASA, are associated with early adolescents' social development indicators (prosocial behavior, self-regulation, antisocial behavior, alcohol use, and 1-year substance use intention). The adherence to social norms was assessed in terms of prosocial behavior, selfregulation, antisocial behavior, alcohol use, and 1-year substance use intention. Three major findings stem from this research. First, a four-group cluster solution in terms of the combination of the parents', teachers', and mentors' perceived autonomy support was the most accurate and interpretable. Two groups gathered similar MASA perceptions across the three sources of support (one classified as low attuned MAS attunement and the other as high attuned MAS). Others, however, depicted misattunement patterns of MAS, one due to low rates of parent autonomy support and the other due to low rates of teacher autonomy support, when compared to the remaining sources.
Second, both high levels of TMAS and high attuned MAS perceptions were associated with significantly higher levels of prosocial behavior and self-regulation. Multiple mean comparisons show, however, that participants who were integrated in the high attuned MAS group showed lower antisocial behavior rates compared to those integrated in the misattuned MAS/low teacher autonomy support. Seemingly, misattuned MAS/low teacher autonomy support group depicted higher antisocial mean rates than low attuned MAS and misattuned MAS/low parent autonomy support, showing that low TMAS and misattuned MAS/low teacher autonomy support represented the worst conditions for the participants' selected indicators of social development.
Finally, comparisons between TMAS and MASA associations with the selected social development indicators were further refined through regression analysis. This analytical option enabled control for age confounding effects, as well as the comparison of TMAS levels and MASA patterns with a reference category that delivered poorer  Results show that while high TMAS was linked to better positive indicators of adherence to social norms, when compared to low TMAS, high attuned MASA was related to better outcomes across all positive and negative indicators of adherence to social norms, when compared to misattuned MAS/low teacher AS. It was also remarkable that all patterns of MASA were associated with lower levels of antisocial behavior and that misattuned MAS/low parent autonomy support was associated with lower rates of 1-year substance use intention when compared to misattuned MAS/low teacher autonomy support. In general, these results propose that for these early adolescents, the amount and the coordination of TMAS and MASA in relation to multiple significant adults are important to estimate social development indicators. However, when comparisons are set with the worst condition (low TMAS and misattuned MASA/low teacher autonomy support), MASA delivers better prospects, especially in the case of deviant behaviors. This is a central finding in this study. The importance of MASA across MSS sources may be salient in early adolescence due to a well-documented reconfiguration of social relationships in this period (Rudasill et al. 2010). Socialization in early adolescence is a fluid process, entailing a decrease of parental centrality (Cotterell 2007) and legitimacy ), greater importance of peers (Fletcher et al. 2011), and the establishment of significant bonds with non-familial significant adults (Schwartz et al. 2013). This relational context may uphold a greater influence of perceived MASA, as opposed to the impact of perceived TMAS amount on socially expected behaviors, but it may also pose some challenges. Early adolescence encompasses the definition of personal decision domain as a symbol of individual autonomy (Smetana and Daddis 2011), which may create greater difficulties to perceived MASA between significant adults and increase interindividual differences in the patterning of autonomy support attunement.
These findings also reinforce that teachers' controlling behaviors, which are misattuned from parents' and mentors' autonomy supportive practices, increase early adolescents' degree of behavioral risk. This result is not surprising, considering that parental and mentor relationships tend to be perceived by youths as closer relationships and that higher levels of teacher AS predict greater prosociality (Roth et al. 2011) and self-regulation (Vansteenkiste et al. 2012), as well as lower rates of antisocial behaviors (Pikó and Pinczés 2015) and substance use (Perra et al. 2012). More importantly, these results echo parallel findings showing that teachers are more often seen as controlling than autonomy  1: age; 2: high TMAS; 3: moderate TMAS; 4: age; 5: high attuned MAS; 6: misattuned MAS/low parent autonomy support; 7: low attuned MAS a Low total AS b Misattuned AS/low teacher AS supportive, possibly due to administrative regulations, demanding learning goals, and educational beliefs (Reeve 2009), especially in countries marked by greater power distance as is Portugal's case (Hofstede 2011). Alternatively, the negative impact of misattuned MAS based on low teacher autonomy support may suggest that these participants understand teaching relationships as more taskrelated or instrumental, leading to greater depreciation of teachers' autonomy supportive efforts (Su and Reeve 2011). It is feasible that bidirectional effects may also be present: early adolescence is marked by a significant decline in academic motivation (Wolters 2003) which, in turn, may lead teachers to adopt more directive styles in their interactions, especially in the case of those teachers with students' behavior regulation duties.

Implications and Limitations
This study has some implications. Research implications are embedded in this study's limitations. The research design is cross-sectional, which means that causality inferences based on this study cannot be made. It is feasible that greater MASA results in optimal conditions for adolescents' social and behavioral development, but bidirectional effects, based on the adolescents' and autonomy support providers' temperament may affect both the level of provided autonomy support, as well as its perceptions. The present findings need, thus, to be grounded on more demanding research principles such as longitudinal designs. In addition, this study was exclusively based on the participants' selfreported autonomy support perceptions and behavior. Although adolescents have been found to be consistent sources of parental practices and of their own behavior (Fletcher et al. 2011), the reliance on a unique source may be a relevant cause of bias, especially when studies are focused on sensitive behaviors, which are subjected to "normalization", such as drug use (Perra et al. 2012). Finally, other contextual, relational, and cultural sources of moderation, such as participants' individual and contextual risk, as well as the examination of the same research goal for educational outcomes (e.g. school grades), must be addressed in further studies within the framework of MAS collective effects.
