When are children satisfied with life? An initiative qualitative study from vietnamese children sample

In the context of research on children's life satisfaction, considering children as active participants are very scarce, the main purpose of the present study was to examine children's perspectives on their life satisfaction. The study used a convenient sample of 228 students from primary and secondary schools, living in urban and suburban areas in Vietnam. The subjects’ average age is 9.51 (SD = 1.56). Data were collected using a single open-ended question. The data analysis was performed by thematic analysis then processed with SPSS 22.0 for quantitative assessment. The results of data analysis indicate the following criteria to consider a child as being satisfied with life: (1) Quality of social relationship; (2) Quality of family relationship; (3) Being engaged in interesting and fun leisure and activities; (4) Achieving desired goals; (5) Living environment; and (6) Some other external factors. Among these qualities, the most important relationships in their lives (including social and family relations) were chosen with the highest frequency, followed by their engagement in meaningful and fun activities, and pursuit of their desired goals. This study provided a better insight into understanding how children perceive life satisfaction and what meanings they attach to it. The research results might be explained from a socio-cultural perspective and provide a scientific basis for large-scale studies on this topic in Vietnam.

Introduction when reviewing the studies on children and adolescents' LS, Gilman and Huebner 15 pointed out that the most common technique for measuring student LS is the self-report scale. However, this method is inherently associated with certain potential limitations (e.g. social desirability). Meanwhile, qualitative studies sought to understand children's perspectives on the matter as active participants are very scarce (e.g. [25][26][27] Therefore, further research whose methodology allows insight into children's subjective perspective on the subject is necessary to develop a more comprehensive LS. Due to the lack of such an approach in this area, we considered the qualitative methodology as the core approach in gathering and analyzing data for the present study. Thus, the present study aims to investigate how children perceive or understand the concept of LS using qualitative data in a Vietnamese sample. We speculate that the findings in our study would help enlighten our understanding of the conceptualization of LS in different cultural. The research hypotheses were as follows: (1) Children perceived LS as a complex and multi-dimensional concept, and (2) Children were most satisfied when having a good relationship with others, including relationships with family members, friends, teachers and others.

Choice of methodology
While the most common technique for measuring LS is using self-report scales, the use of qualitative assessment methods, such as open-ended questions, allows the collection of information on participants' perceptions, views, and beliefs in their own terms, in contrast to the external definitions and categories preestablished by researchers, which is typical of quantitative inquiries. 28 As mentioned by Patton, 29 the truly open-ended question "allows the person being interviewed to select from among that person's full repertoire of possible responses…." (p. 296). This methodology allows free expression of individual comments and opinions from the interviewees and can be used for a wide range of applications. Particularly, it is useful for exploring new topics or understanding complex issues. 30 In addition, Patton 29 also confirmed that qualitative methods have an important unique advantage which is that qualitative data can be transferred into quantitative data for research purposes. On such a basis, collected information can be deployed on a large number of subjects.
In this paper, through qualitative analyzes of data collected from an open-ended question, we investigated how children define LS in their own terms. From these qualitative findings, we expected to get new insights into the Vietnamese children's definition of LS, thus, laying the foundation for constructing a reliable and valid psychometric scale for measuring the level of Vietnamese children's LS in the future.

Purposive sampling
In line with the research's aim, we chose to collect data from schools because as part of the compulsory school system, primary and secondary schools allow access to the full spectrum of social demographic profiles of a child. Thus, the most common sampling procedure for qualitative research: purposeful sampling was used. 31,32 Respondents comprised of students from two areas (the urban and suburban) of X city in Vietnam. A sample of 228 students from primary and secondary schools participated in the study. The sample consisted of 55.30% males with an average age of 9.51 years (SD = 1.56). In line with Patton, 33 students from 8 to 12 years old were chosen as respondents because of the advantage of homogeneity in terms of psychological development. Table 1 presents the detailed socio-demographic information on children in our study:

Measurement
A questionnaire, including two closed-ended demographic questions and one open-ended question on LS, was delivered to all participants. Participants were invited to define LS in their own words through a single open-ended question: "When do you feel most satisfied with your life?". Two close-ended questions helped us collect some information about the socio-demographics of the population, namely, age and gender, that will be used for further analysis in another quantitative phase.

Procedure
Within the scope of this research, in order to collect the students' answers to occur auspiciously and legally, we utilized the gatekeeper as part of the data collecting method. While in research that occurs in public space, such as streets, parks, public markets, and so on, researchers are usually exempted from getting the gatekeepers' permissions, researches that take place within school campus needs permissions from both participants and school officials. The reason is, legally, all institutions have an autonomous right to permit or deny access to their information, space, and personnel. Thus, for the study, during the surveying process, we had to mobilize the principals and the teachers to receive permission prior to collecting responses from students.
With the permission of these gatekeepers, we carried out the data collection from the students. All the participants and their parents were informed about the specific objective of the study before proceeding to fill out the questionnaire. According to the most recent periodic examination records provided by the school administrators, all participants had

Coding process
Coding was completed by the three authors of this article. The process involved three stages, namely, planning, checking, and finalizing. In the planning stage, we carefully read and re-read each answer given by each participant and familiarized ourselves with the opinions expressed by children included in our study. During this phase, every member of the research team sorted out quotes and noted any questions, ideas, or explanations that emerged. After the discussion, two researchers began coding the answers obtained. A preliminary coding plan was constructed, and all potentially relevant features were included. The checking stage involves comparing the two coding versions. One by the aforementioned researchers and the other, conducted independently by the remaining author. Based on the preliminary coding results, a revised coding plan was brought about with an adjusted number of the coding features. Specifically, the number of codes was reduced from 24 to 15 codes for the 942 responses collected from participants.
In the finalizing stage, all the answers were coded carefully again by all three authors and put into five categories based on the revised coding plan. Throughout this procedure, the codes were further refined, and the results are illustrated in Table 2.
Besides, we noticed some expressions on LS, which were irrelevant to the aspects of life as well as the psychological features mentioned in the coding process. These are temporarily recorded as "other external factors" (e.g. Have nice clothes; Younger brother stop going through backpack; Young sister talks less; To be born).

Categories of LS
During the process of data coding, it was found that all participants were able to form their own opinions about when they were most satisfied with their lives. In other words, no participants considered LS as a vague and indescribable concept. The results of the thematic analysis showed that LS was defined in the following aspects by children: It is a noticeable feature from our collected data that most children, when asked, define LS as positive and joyful expressions and experiences in their lives. For instance: "I am most satisfied when helping others. Others help me when I am in need"(Male, 9 years old); "I am most satisfied when I am complimented by teachers, loved by parents, liked by friends"(Male, 7 years old); Members of the family get along, are happy, and play together; everyone is healthy. Being cared for, loved, taken care of and supported by parents, grandparents.
The idea of receiving compliments, love, encouragement and care from members of the family. Can support parents, grandparents, relatives in the family.
The idea of being able to help grandparents, parents in doing house-works.

Quality of social relationship
Have good friend, likable friend, friends who get along and help one another.
Relate to the desire of having many good friends, getting along with friends, closely-knitted friends who support one another in study and in life. Be able to go to school, play, and participate in activities with friends.
The way that children perceive their friendship quality in the school context. Be respected, loved, supported, complimented and supported by everyone.
Relate to the desire to have positive relationships with everyone around (neighbors, relatives, and even strangers). Be respected by teachers and able to please teachers.
The need to be respected by teachers, to please the teachers. Be able to help others.
Children's perception on bringing joy to others, helping those who are struggling. Engagement in interesting and fun leisure and activities Take a break from school, go out, participate in outdoors, leisure activities after school hours.
Perception of children related to activities in leisure time.
Eat favorite food. The idea of being able to eat favorite food, good food. Have books, objects, toys bought for, have gifts given to. Perception on physical appearances, health of the children themselves.

Living environment
Friendly environment, no more poverty or diseases.
The idea of a peaceful, prosperous society with no poverty, diseases, natural disaster.
"When I get along with everyone and can expand my exploration everywhere is when I am most satisfied"(Female, 11 years old); "I am most satisfied with life when my family are always healthy, closed and loving, protect one another"(Female, 7 years old); "When I get high scores on subjects at school is when I am most satisfied with life"(Female, 10 years old).
As these quotes and the answers shown in Table 3, the children tend to see the times when they feel most satisfied with life in terms of what leads to LS rather than defining what LS is. In other words, the children state that they are content when having a good quality of relationship with family and society, engaging in fun, interesting activities outside of class; pursuing and achieving personal goals; living in a developed, safe and friendly environment. Especially, when discussing the relationship aspects, including family and social relationships, the results revealed that children are likely to be more satisfied when they're being loved, being cared for, or participating in activities with others. In particular, in family relationships, the answers related to the code "Being cared for, loved, taken care of and supported by parents, grandparents" were mentioned 123 times, taking up nearly 50% (49.9%) of the total of answers found in this category.
Similarly, in the social relationship aspect, 92 out of 342 answers (taking up 26.90%) stated that satisfaction is when they are "able to go to school, play, and participate in activities with friends."

Major domains of life that contribute to LS
The results of thematic analysis in Figure 1 shows that children's LS can be defined within the following aspects: (1) Quality of social relationship; (2) Quality of family relationship; (3) Being engaged in interesting and fun leisure and activities; (4) Achieving desired goals; (5) Living environment; and 6) Other external factors.
The data in Figure 1 indicates that with 342 answers, equivalent to 37.01% of the obtained answers, having a good social relationship is the most commonly found factor when children perceive themselves to be satisfied with life. The next commonly found themes are having a good family relationship and being engaged in interesting and fun leisure activities, respectively. In other words, when describing their LS, respondents in the study describe it in terms of intrapersonal relations, participation in specific activities, mostly doing interesting things, and attainment of their desired goals (e.g. good grades).
Thus, it can be seen that according to the respondents, two main aspects of life emerged as the most important LS dimensions are (a) The quality of social relationships, including relations with friends, teachers, being a good person, and being kind to others; and (b) The quality of family relationships.

Discussions
Our research finding revealed that most participants have the capability to interpret satisfaction as one's attitude towards life in general. This finding is entirely aligned with what Diener and colleagues 4,34 found in their study, which is that satisfaction is conceptualized as reflective cognitive assessments of one's life. In line with previous studies, children in the present study reported their LS as complex and multidimensional 11,35 and in the positive range. 27,36,37 The importance of relationships with others Our finding also implied that, in defining LS, children highly emphasize the importance of relationships with others, especially between peers and family members. The emphasis on quality relationships in children's perception of general well-being can also be found across many previous studies. [25][26][27]38,39 Particularly, in our study, children emphasized the importance of social relations (including friends, peers, as well as teachers) as the most vital interpersonal resource for their LS. From the developmental psychology point of view, this finding is compatible with children's natural development at this age. During this stage of development, children focus not only on their studies but also on their relationships with peers. Throughout close friendships, children can freely express themselves, as well as give and receive feedback and support when needed. That is why positive peer relationships and friendships are very important for children in forming identity and personality. 40 Besides social relationships, relationships among family members also held a significant role in creating the perception of LS in children. As Do Long 41 has pointed out, in traditional Vietnamese culture, individual identity is not seen separately, but always in relation to a series of integrated systems that the individual belongs to. Children's focus on the relationship among family members can be seen as a specific domain of their LS. Although this conclusion has also been suggested in other studies on the topic (e.g., 27,42 ) it could also be explained based on the cultural-social reality in Vietnam. Accordingly, despite major changes in Vietnamese society, the family has always played an essential role in forming and developing Vietnamese children's personalities. The Vietnam proverbs such as "blood are thicker than water" (một gio ̣t máu đào hơn ao nước lã), "brothers and sisters are as close as hands and feet" (anh em như thểtay chân) implies that the tradition of the close-knitted family has been embedded into the cultural fabrics of Vietnamese children and adults daily life philosophies. In fact, the family aspect has been recognized as a stable dimension of Vietnamese teenagers' selfesteem through many previous studies. 43,44 Furthermore, a recent qualitative study on happiness in the Vietnamese population at the early stage of adulthood suggested that positive relationships with other family members are also considered as one factor that brings happiness from the respondents' viewpoint. 24 Fun leisure and activities Participation in leisure activities has been widely recognized as one of the fundamental human rights. 45 The previous study also pointed out that playtime and leisure activities are central parts of children's daily lives. 46,47 It is through participation in such activities that children form friendships, develop skills, and experience enjoyment, 48,49 thereby providing mechanisms for coping with life stress. 50 Therefore, it is not surprising that children in this study also report that besides social and family relationships, leisure time activities are also of considerable importance. Both family and school environments were considered core settings that reinforce children's socialization by forcing them to comply with certain sets of rules or codes of conduct. Thus, leisure activities in spare time were ideal opportunities for children's development of autonomy and competence needs since strict controls from their parents and teachers should be loosened, and they will be given more available space to act on their own. 51 Thereby, gaining autonomy in children's personal environments is achieved in part through leisure experiences. 50 However, from children's responses, it is evident that the leisure activities mentioned did not seem to relate to the process of identity construction. In other words, these activities were described simply as instruments to having fun.
It is also worth noticing that most children who participated in the study did not state learning at school as part of what they found satisfying in life. This finding could be understood through the general tendency in children to often find schools as obligatory and formal rather than a joyful and interesting environment. Therefore, apart from emphasizing social relationships created at schools (e.g. relationships with peers, teachers), children mainly focus on activities outside of school to satisfy them. As this trend was also found by Vujčićet al., 27 this study further consolidates their qualitative finding in this sample. According to these authors, young people often criticize the education system in terms of (a) its high workload and pressure; (b) difficulties in finding meaning and value in some school activities, and (c) the lack of opportunity to exercise their talents and work on their intrinsic goals. Our findings further broaden the idea that settings outside of school and family contexts, such as community-based and after-school activities, are also vital to the fulfillment of children's LS. 52 Several studies have shown that participation in these settings during middle childhood would anticipate positive academic achievements and emotional adjustment, and promote competence in several key developmental tasks, including school engagement, and social behaviors and relationships. 53,54 It has been demonstrated that children involved in formal activities report significantly greater enjoyment than those who participated in unorganized and spontaneous activities. 55 In line with the finding, we agree that having extracurricular activities organized by the school such as sports, clubs, student newspaper, music, art, or drama are also essential to attain student's satisfaction. By spending a large proportion of their time at school with their teachers and peers, extracurricular would become a valuable resource to maintain children's LS and prevent them from involving in risky behaviors in the future. 56

Goals and living environment
From children's statements gathered in the study, it can be found that a considerable proportion of the children perceived LS occurs when they achieve their personal goals. This result could be seen as a positive signal in children's personality development and formation. The reason being those goals motivates actions; without goals, there are no actions. As Locke 57 suggested, "goals determine the direction, intensity, and duration of action" (p. 304).
Although children do not see the learning activities themselves as the source of LS, they did report finding it satisfying when they get high achievements in education. One way to explain this phenomenon can be through a historical-cultural perspective. In Vietnam, with the influence of Confucianism, Vietnamese people, children, in particular, have always attached great importance to education since ancient times. In fact, during some periods in history, education was considered the only way to success. Therefore, even though Vietnamese society has gone through many changes, most people still believe that their future depends on their learning outcomes at schools. Good academic results lead to a good future and vice versa. 44 Thus, culture could explain why children perceive their satisfaction mostly in connection with achieving their academic goals.
It is suggested that those who defined their LS based on their academic achievements but did not satisfy it could evoke a great deal of contradiction and frustration. Therefore, it is suggested that creating a positive classroom climate would help boost students' morale and motivation to strive for better achievements. Baker et al. 58 asserted that "the sense of connectedness to others and support from the social environment are well-established correlates of resilience and contribute to numerous positive outcomes for children" (p. 211). Accordingly, emphasizing a child's strengths and promoting positive interactions and emotions in school serve to improve both individual performance and total school functioning, 59 thereby improving children's LS.
In addition to perceiving the achievements of life goals and dreams as times where they feel most satisfied, children also report dreaming about a good living environment as a factor in their perception of LS. However, different from previous findings where it has been suggested that living environment consists mainly of school facilities or family socioeconomic condition (e.g., 27,42 ) the participants in our study mentioned both their immediate surroundings and society as a whole. In this regard, children expressed their desire for a peaceful, developed society where there is no longer any natural disaster, poverty, or diseases and everyone lives happily. This is a positive signal in children's cognitive development because childhood and adolescence are considered dynamic and critical periods in one's development. While their learning of ecological worldview in formal schooling is often superficial and insufficient, 60 this result implies a positive and active aspect in children in exploring the world around them, contributing to building a great personality in this target group in the future.

Conclusion
The findings of the current study supported the research hypotheses and contributed to the existing literature by revealing how children understand satisfaction and what meanings they attach to. The present study has provided insights into how children understand and perceive LS. In general, most children see LS as positive and joyful expressions and often link it with their own experiences. These experiences are reported from this study's sample as strongly related to the quality of the most important relationships in their lives (including social and family relations), their engagement in meaningful and fun activities, and their pursuit of their desired goals. In other words, children feel satisfied when their important relationships are warm and supportive and when they have a sense of autonomy and agency in their lives.
However, this study has its own limitation. Although students at schools are diverse in social status, the utilization of convenient samples of Vietnamese students may limit the generalizability of the finding to the entire population. Thus, further research surveying different groups of Vietnamese children is important to validate the current research as well as in implementing a LS scale for children that is anchored in the Vietnamese culture. The present study is just an initial step in this direction.
