Psychological care of caregivers, nurses and physicians: a study of a new approach

There is much evidence demonstrating that psychosocial interventions in caregivers and oncological staff produce an improvement in their patients' quality of life. The aim of this explorative study was to evaluate the effect of a new approach in promoting more functional ways to face stressful situations in the constellation of people around patients: caregivers, physicians and nurses. Thirty-four subjects were divided into three groups: 10 caregivers, 11 physicians, and 13 nurses. A “Balint Group” method modified according to a mindfulness technique was used as the intervention. Three assessment tools were administered to the participants at baseline, during, and after completion of the study: the Response Evaluation Measure (REM-71), the Satisfaction Profile (SAT-P), and the Group Climate Questionnaire (GCQ). Mean values of defense mechanisms determined by the REM-71 were compared with those of the standard population. At baseline, we observed a prevalence of immature defenses in the three groups, with mean values above those in the standard population. After the psychological intervention, a tendency to normalization of the mean values was observed, indicating the development of more adaptive ways of using defense mechanisms and the effectiveness of the intervention. Group climate, assessed through the GCQ, showed an increase in the “Engagement” factor and a decline in the “Conflict” factor in all groups. This study suggests that group treatment focused on changing personal responses to stressful situations can induce more adaptive strategies enabling caregivers, hematologists, and nurses to help patients better and thereby improve their quality of life.


Introduction
There is growing consensus that psychosocial support should be integrated into the routine care of patients with cancer [1][2][3][4]. A more recent concept is to extend this support to the patients' physicians, nurses, and caregivers (husbands, wives, or relatives) [5,6].
Patients tend to focus on their illness and their body. However, their emotional burden often causes the adoption of strong dysfunctional defense mechanisms that can bring them to deny the idea of being ill and consequently to refuse or not seek the help of medical staff [7,8]. Denial and negation defenses can delay the diagnosis and reduce adherence to treatment and follow-up [9][10][11][12].
Caregivers can be the link between patients and physicians, supporting and creating a good alliance between the two that is considered essential for patients to overcome dysfunctional defense mechanisms. Psychosocial intervention for caregivers can be of paramount importance in improving the quality of life of patients and their families [13,14], especially in terms of better global functioning.
Patients and caregivers are not, however, the only protagonists of the battle against cancer. Oncologists and nurses deal with existential questions of life and death daily, which are always difficult issues to face and manage. It has been demonstrated that medical oncologists are more prone to experience symptoms of depression than other internal medicine physicians and this phenomenon can be observed even during their training [15][16][17]. If these difficulties are not recognized promptly they can lead to burnout, a syndrome characterized by a loss of enthusiasm for work, a feeling of cynicism, and a low sense of personal accomplishment, which can cause medical errors and malpractice [18,19]. Other factors can contribute to the development of a burnout: excessive workload, a sense of impotence, frustration, limited autonomy, and a perception that one's own work is meaningless. These factors might further reduce autonomy and efficiency, increase workload, and reduce the willingness to interact with patients, thereby worsening the relationship between patients and medical staff [20,21]. This is an important point as one of the causes of depression in patients is a poor relationship with physicians, or in general with all the oncological staff [22]. Emotional distress is also a strong predictor of poor selfmanagement and high health care costs.
Given the prevalence of distress among oncologists and its implications for patients and their care, it could be important to make physicians undergo periodic screening or monitoring for burnout particularly because they often do not look for help. There is now considerable evidence that any intervention in oncological staff and caregivers increases their capacity to bear emotional burdens and consequently improves the patients' quality of life [23].
Starting from these observations, we decided to focus on the "constellation" of people (nurses, physicians, and caregivers) around patients affected by multiple myeloma and designed a pilot study. The project, conducted in the three groups, was focused on the identification of personal responses to stressful situations (defense mechanisms) evaluated through several assessment tools administered to the participants at baseline and after completion of the psychological intervention. The identification of defense mechanisms against illness is of the utmost importance: on the one hand, these mechanisms represent a way of coping with anxiety triggered by threat, on the other hand, they allow people to establish new ways of relating with the world and with themselves. The aim of this explorative study was to evaluate the effect of a group intervention in improving caregivers' knowledge and quality of life, and in promoting among physicians and nurses a different way of facing the difficulties of their job.

Participants and interventions
An explorative study was carried out between caregivers, physicians and nurses of Policlinico San Matteo of Pavia, Italy. Hematologists and nurses participated voluntarily; the caregivers invited to participate were sampled stratifying for phases of disease (onset, relapse, advanced phase). The number of participants from each group who dropped out during the study was recorded (early and late dropouts). The study was approved by the Ethics Committee of Policlinico San Matteo of Pavia, and all participants signed a written informed consent.
The research was divided into three phases: the preintervention phase (T0), the intervention period, and the follow-up (T1).
In the preintervention phase, individual interviews, of 50 min each, were conducted by a clinical psychologist to introduce the topic and the objective of the research, to administer the questionnaires response evaluation measure (REM-71), Satisfaction profile (SAT-P), and to investigate the present level of personal satisfaction and stress. The questionnaires, anonymous and self-compiled, were the same for all participants.
In the second phase of the study, the intervention period, each group (caregivers, physicians, nurses) was planned to have 30 sessions, each of 60 min, using a "Balint Group" method [24,25], modified according to a mindfulness technique [26,27]. This method promotes a group process of exploration and training based on reflection about relational experiences with patients, focusing on development of attentive awareness of sensations, thoughts, and perceptions of reality at the time of the session. The group leader presented the topic of each discussion. At the end of each session, an anonymous questionnaire group climate questionnaire (GCQ) was administered to all participants.
In the final phase (T1), at the end of all sessions (after 1 year), the same procedure as in the preintervention phase was used.

Assessment tools
The research was focused on the identification of personal responses to stressful situations and then on the development of more adaptive ways of managing these situations. The assessment tools (REM-71, SAT-P, and GCQ) were not specific for the populations in the study.

Response evaluation measures-71
The REM-71 [28] is a self-report questionnaire to assess defense mechanisms in adults through the use of 71 items, measured on a Likert scale from 1 (complete disagreement) to 9 (complete agreement). The scale defines defenses as self-regulatory processes that could be considered metrics of positive psychological health. The theoretical approach of the instrument implies a developmental model of defenses placed along a continuum of maturity-immaturity. The scale's validity is supported by several studies involving adults, adolescents, and school-aged children. Defenses were grouped into two factors: Factor 1 (immature defenses) and Factor 2 (mature defenses) [29] ( Table 1). Factor 1 comprises 14 defenses that distort reality in accordance with expected outcomes, leading to less adaptive functioning. Factor 2, by contrast, comprises seven defenses that attenuate unwelcome reality, allowing more adaptive functioning. We considered estimated values ≥4.4 [30] as indicating a potentially dysfunctional way of using defense mechanisms. Mean values of defense mechanisms obtained through questionnaires were compared with those of the standard population [30].

Satisfaction profile
The SAT-P [31] is a self-report scale widely used in the health care context. The scale defines satisfaction as the result of a cognitive process that compares real with ideal expectations. Level of satisfaction is linked to the gap between real and ideal expectations. The SAT-P assesses subjective satisfaction in the preceding month using five macro-categories: psychological and physical functioning, work, sleep/diet/free time, and social functioning. The questionnaire consists of 32 items, measured on a visual analog scale: the level of agreement with a statement is indicated by marking a position along a continuous line (10 cm) between two end-points (totally satisfied/totally dissatisfied). It assesses a satisfaction profile that should be integrated with clinical data.

Group climate questionnaire-short version
The GCQ [32,33] is a self-report questionnaire consisting of 12 items rated on a 6-point scale, from 1 = not at all to 6 = extremely. It measures how members consider their group experience through three scales: engagement, conflict, avoidance. Engagement is the degree of cohesion and work orientation of the group. Avoidance is the degree to which individuals rely on group members and leaders. Conflict consists of the subscales friction, distrust, and mutual withdrawal. The GCQ was administered after every group session.

Statistical analysis
Data were described as means and standard deviations (SD), if continuous, and as counts and percentages, if categorical. Within-subject comparisons of scores were performed by means of a general linear regression model for repeated measures, with calculation of robust standard errors to account for within-subject correlation. Mean changes and 95% confidence intervals (95% CI) were computed. The association between GCQ scores and number of sessions was assessed with Spearman's rho coefficient. For this analysis, data were anonymous and were pooled across groups.
Stata 12 [34] was used for statistical computations. A two-sided P-value <0.05 was considered statistically significant.

Results
Thirty-four subjects were enrolled in the study (10 caregivers, 11 physicians, and 13 nurses). Four participants (two caregivers, one physician, and one nurse) dropped out the study, three within the first 3 months (early dropout) and one after 3 months (late dropout). The three early dropouts, one caregiver, one physician, and one nurse, stopped participating for employment reasons; the other caregiver (the late dropout) withdrew from the study because of the worsening clinical condition and unbearable increased care of the relative.
The comparison of the mean values of defense mechanisms in caregivers at baseline with those of the standard population (Table 2) showed higher values for four immature defenses: fantasy, conversion, projection, and repression.
The follow-up analysis performed after the intervention showed a general tendency to normalization with a significant increase in mature defense mechanisms (such as humor, idealization, and denial) and a decrease in many immature defense mechanisms, in particular, those that had been found to be significantly higher with respect to the standard population (fantasy, repression, projection, and conversion). We also observed an increase in one immature defense: suppression. Changes between before and after the group intervention and the 95% CI are illustrated in Figure 2A.
At baseline, SAT-P results were all within the range of the standard population. This finding conflicted with the information that emerged from the individual interviews which revealed remarkable difficulties in managing everyday life. After the intervention, all scores for quality of life perception increased by 10%-20%, although this improvement just fell short of being statistically significant ( Table 3).
As regards the GCQ (assessed at each session), the number of followed sessions showed a direct correlation with the "Engagement" factor and an inverse correlation with the "Conflict" factor (Table 4).
The comparison with the standard population ( Table 2) showed that hematologists, like the caregivers, prevalently used immature defense mechanisms, in particular: fantasy, conversion, and projection.
The analysis after the intervention highlighted a significant increase in mature defenses (such as humor, altruism, idealization, and denial), and a decline of many immature defenses, in particular, those identified as being significantly more frequent with respect to the standard population: fantasy, conversion, and projection. There was clear evidence of a general tendency to normalization for all defenses. Changes between before and after the group intervention and the 95% CI are illustrated in Figure 2B.
The preintervention evaluation of perceived quality of life showed the same discrepancy as in the group of caregivers between what was picked up by the SAT-P results, which were all in the standard population average, and what emerged from the interviews. In this group, the change from baseline was very close to zero, and far from being statistically significant (Table 3). Climate group evaluation showed a direct correlation between the number of followed sessions and the "Engagement" factor, and an inverse correlation between the number of followed sessions and "Conflict" and "Avoidance" factors (Table 4). However, these relations were not statistically significant.  Figure 2. Changes between, before, and after treatment and 95% confidence intervals, in the three groups: caregivers (A), hematologists (B), and nurses (C).
Before the intervention, the SAT-P results were all similar to those in the standard population. As for the hematologists, there were virtually no changes in the SAT-P score in nurses after the intervention (Table 3). Once again, there was an evident discrepancy between the results of the questionnaire and the interviews.
As for the hematologists, the number of followed sessions showed a direct correlation with the "Engagement" factor and inverse correlations with "Conflict" and "Avoidance" factors, but these relationships were not statistically significant (Table 4).

Discussion
The emotional burden of caregivers has usually been characterized in previous studies as creating anxiety and depression with a low quality of life (both physical and psychological). For nurses and physicians who deal with oncological diseases, most studies have focused on burnout and its personal (anxiety, depression) and professional (malpractice) consequences. In both cases, wellbeing and personal growth were measured in terms of specific symptoms and consequently any therapeutic approaches were addressed at eliminating these symptoms.
In contrast, the new approach adopted in this explorative study arose from the belief that a reintegration of personal satisfaction cannot be obtained only from reducing symptoms or improving quality of life, but requires the development of more functional and mature ways of facing reality and its stressful situations, such as severe illness.
The analysis performed at baseline, prior to the intervention, showed a high frequency of immature defenses Table 3. Satisfaction profile scores of the three groups before (T0) and after (T1) treatment, with associated 95% confidence intervals and statistical significance. in all three groups: this implies less functional and adaptive ways of facing everyday situations and a low acceptance of reality. This was confirmed by the comparison of our sample with the standard population; all three groups showed, as a common finding, three immature defenses: fantasy, conversion, and projection. The use of these mechanisms of defense is consistent with evoking a death fantasy as a consequence of a confrontation with a severe illness. Conversion is a defensive response to death and contamination anxiety evoked by illness. It could be considered as an unconscious identification with the sick role, reproducing somatic symptoms observed in patients to reduce stress. Projection is a way of transferring unacceptable feelings, such as anger, to other people, that is turning the inner danger into an outer one. For example, the hospital environment could be perceived as constantly hostile and dangerous. Fantasy is a way of coping with problems and situations that evoke great impotence through an excessive use of daydreaming as a substitute for human relationships, more direct and effective action, or problem solving. The frequent use of fantasy as a defense in this context could also embellish the interpretation of somatic symptoms, leading to the idea of being affected by a serious illness. Contrariwise, the use of repression as a defense mechanism, which was more common in caregivers than in the standard population, could lead to an inability to remember diseases, shifting attention to specific symptoms of illness or to drug-related side effects. The effect of the psychological intervention was evident in all groups. We observed a decrease of immature defenses, including those that were more present in our study groups at baseline than in the standard population and an increase in mature defenses (humor, idealization, and denial) after the intervention. Altruism increased among physicians and nurses especially in solidarity and cooperation with the colleagues. By contrast, altruism remained stable in caregivers, due to its high value at baseline. An increase in mature defenses implies a greater ability to accept and mitigate the unpleasant aspects of reality, with consequent better self-management.

Factors
This trend to normalization in the use of defense mechanisms, in common to all the groups, is a clear indication of the effect of the intervention. Of note, in caregivers and nurses, suppression, which was within the normal range for standard adults at baseline, increased after the intervention. This could be due to the short duration of the intervention and so it might indicate a transitional stage, as already well described in psychotherapy literature. This phenomenon is explained by the fact that defense mechanisms are structures that change slowly, requiring time to develop and become stabilized [35].
During the intervention, cohesion increased in all three groups and the avoidance of personal responsibility of work group decreased. Cohesion is comparable to therapeutic alliance in individual psychotherapy [36]. Our approach was also effective in creating a good group climate focused on more productive cooperation and support. However, although significant, the correlation was weak.
Quality of life perception did not change significantly after the invention, except for a relevant, but not statistically significant, increase in scores in the caregiver's cohort only. This could be due to the caregivers' greater attendance at sessions, which implied reinforcement of the group treatment, in line with the GCQ results.
In conclusion, this study suggests that a work group, promoting sharing and collaboration, leads to the induction of mature defenses enabling reality to be faced in a more adaptive and effective way. As defense mechanisms are unconscious functions, once established, people keep on using them in their everyday life. The development of more adaptive strategies can help caregivers to accept their new stressful condition, and consequently provide better assistance for the people they are caring for, and can help hematologists and nurses foster better ways to face frustration and impotence, in order to prevent burnout and facilitate their relationships with patients. Therefore, results of this study offer a useful starting point for the planning and the development of future studies with the aim to evaluate the efficacy of the "Balint Group" modified method on caregivers' quality of life and on the ability of physicians and nurses to deal with stressful situations.
