Differentiation of self, anxiety, triangling and distress: A test of Bowen theory.

Based in Bowen theory (Kerr, 2019; Kerr & Bowen, 1988), this study examined differentiation of self as a moderator of the relationship between anxiety and current triangling among a sample of adolescents. It also explored the relationship between specific triangle subtypes and psychological symptoms. We hypothesized that higher levels of anxiety would be associated with higher levels of triangling, and that this relationship would be weaker for participants who report higher levels of differentiation of self. Additionally, we hypothesized that psychological symptoms would be significantly lower for those who indicated a balanced triangle configuration to characterize their family structure (as compared to those selecting scapegoating, cross-generational coalition or mediator patterns). Results partially supported our hypotheses; differentiation performed as a moderator in two analyses, but not in others. Higher levels of psychological symptoms were associated with experience with mediator and cross-generational triangling.

The Attachment Versus Differentiation Debate: Bringing the Conversation to Parent-Child Relationships.

This article contributes to the attachment versus differentiation debate, bringing the conversation to parent-child relationships. While attachment theory's (AT) approach emphasizes bonding, Bowen family systems theory's (BFST) differentiation approach emphasizes emotional boundaries. They both suggest that balancing autonomy and connection is important, but AT conceptualizes this in terms of the parent's ability to meet the child's needs for autonomy and connection, while BFST conceptualizes this in terms of the parent's and child's ability to be connected due to mutual respect for each other's emotional boundaries. They similarly recognize that: (1) emotionally mature parents respect children individuality, (2) emotionally immature parents may project their needs and wishes onto children, and (3) emotionally mature parents focus on calming themselves to help their children to be calm. They differ in that: (1) BFST suggests that children may project their needs and wishes onto their parents and intrude on their parents' emotional boundaries, and AT does not conceptualize this; (2) BFST suggests that caregiver over-involvement may be experienced as positive for a child and program them to be excessively needy, and AT suggests that caregiver over-involvement is negative for children and neediness is caused by under-involved caregiving; and (3) BFST suggests that therapists should not try to be a parent to their clients as this can replicate the fusion that the client experienced with their parents, and AT suggests that therapists should try to be like a good parent to their clients to help them to develop more secure attachment styles.

The Effects of Role Differentiation Among Clergy: Impact on Pastoral Burnout and Job Satisfaction.

The present study investigated the impact of differentiation of self as an emotion regulation strategy on work and family conflict, ministerial job satisfaction, and burnout for pastors. Specifically, does differentiation of self provide a psychological resource for pastors coping with the experience of burnout as emotional exhaustion, given the unique social context of the pastor's family and the role emotional labor has in causing burnout in social service professions? A unique aspect of the pastorate is the pastor's family's social context of living with the congregation. Due to this unique social context, work and family conflict were investigated as predictors of pastoral burnout. A sample of pastors (N = 164) was surveyed to investigate the impact of differentiation and job satisfaction on personal and work-related burnout. Findings suggest that differentiation of self provides a resource against the personal experience of burnout, while ministerial job satisfaction buffers pastors against work-related burnout.

Marital interactions and experiences of women living in polygamy: An exploratory study.

The study examines interactions and experiences of Bedouin women living in polygamous households in Israel. A mixed-method approach was applied in a two-part study. The quantitative part examined differences in differentiation of self and marital satisfaction between 50 Bedouin women in polygamous marriages and 50 in monogamous marriages. It found that, in polygamous families, women's levels of marital satisfaction were positively related to their I-position and fusion with others and negatively related to emotional cutoff and number of children at home, whereas among monogamous counterparts, marital satisfaction was only negatively associated with emotional cutoff. Surprisingly, fused relationships with the family of origin predicted higher satisfaction only in women in polygamous marriages. The qualitative part, which yielded deeper understanding of the authentic voices and experiences of 18 senior wives, revealed that they had severe emotional and physiological responses to their husbands' marriage to another woman. For most, particularly those who married young, living in a polygamous family adversely affected their marital satisfaction. Interactions ranged from violent relationships, accompanied by jealousy and anger, to respectful and harmonious relations. Along with the challenges, some women, especially the educated, chose proactive ways of coping. Educated women also preferred cohabitation with the other wife.

Couple Adjustment and Differentiation of Self in the United States, Italy, and Spain: A Cross-Cultural Study.

This study comprises a first attempt to explore a cross-cultural application of Bowen family systems theory and examines the relationship between differentiation of self and couple adjustment using measurement invariance. A sample of 2,141 individuals (n = 915 from the United States; n = 635 from Italy; n = 591 from Spain) completed measures of differentiation of self (DSI-R; Skowron & Schmitt, J Marital Fam Ther, 29, 2003, 209) and couple adjustment (DAS; Spanier, J Marriage Fam, 38, 1976, 15). Results showed evidence of partial measurement equivalence for the DSI-R across the three samples. Additionally, results from latent regression showed that less emotional cutoff predicted greater couple adjustment in the United States, Spain, and Italy, whereas greater emotional reactivity predicted poorer couple adjustment only in the more collectivistic cultures, Spain and Italy. Our findings are consistent with prior empirical studies, which suggest that emotional cutoff is a strong predictor of relationship adjustment. The use of measurement invariance provides a foundation for future studies to continue employing rigorous statistical methods when examining constructs across different cultures. The findings highlight culture-specific similarities and differences in differentiation that may benefit practitioners by informing psychotherapy with individuals, couples, or families from diverse populations.

Este estudio constituye un primer intento de explorar la aplicabilidad intercultural de la teoría de sistemas familiares de Bowen y de analizar la relación entre la diferenciación del self y el ajuste de la pareja utilizando un análisis de invariancia. Una muestra de 2.141 personas (n = 915 de Estados Unidos; n = 635 de Italia; n = 591 de España), completaron medidas de diferenciación del self (DSI-R; Skowron & Schmitt, 2003) y de ajuste diádico (DAS; Spanier, 1976). Los resultados aportan pruebas de equivalencia parcial de las medidas del DSI-R entre las tres muestras. Además, los resultados de la regresión latente indicaron que un menor corte emocional predijo mayor ajuste de la pareja en Estados Unidos, España e Italia, mientras que una mayor reactividad emocional predijo un menor ajuste de la pareja solo en las culturas más colectivistas: España e Italia. Nuestros resultados concuerdan con estudios empíricos anteriores, que sugieren que el corte emocional es un fuerte predictor del ajuste relacional. El uso del análisis de invariancia ofrece una base para que futuros estudios sigan utilizando métodos estadísticos rigurosos cuando se examinan constructos entre culturas diferentes. Los resultados ponen de manifiesto diferencias y similitudes específicas en la diferenciación entre las culturas estudiadas, que pueden ayudar a los profesionales orientando la psicoterapia de personas, parejas o familias de poblaciones diversas.

Secondary traumatization and personal growth of healthcare teams in maternity and neonatal wards: The role of differentiation of self and social support.

It is of utmost importance to examine the consequences of healthcare teams' daily exposure to stress. This quantitative cross-sectional study examined the connection between exposure, secondary traumatization (stress deriving from helping suffering others), and personal growth. It compared the teams in maternity and neonatal wards with colleagues exposed to different levels of illness and death and examined the contribution of social support and self-differentiation to personal growth. One hundred forty-nine Israeli physicians and nurses participated, comprising three groups (maternity and neonatal wards, exposed to suffering as well as to new life; high; and moderate-to-low exposure to illness and death). Data were collected through an online program (64.78% response rate). Whereas no group differences in secondary traumatization were found, personal growth was higher among individuals from maternity and neonatal wards. The higher the social support and self-differentiation, the higher was the personal growth. The findings highlight the necessity to design interventions to empower social support and investing in its development on both the organizational and personal level, especially for the maternity and neonatal wards' healthcare teams.

Parenting among mothers exposed to ongoing military conflict in childhood: An exploratory study.

Mothers living in areas exposed to ongoing military conflict are at higher risk for psychological difficulties, such as posttraumatic stress disorder, than those not living in such areas. The aim of this two-part exploratory study was twofold. The first aim was to examine differences between mothers who grew up under ongoing military conflict in childhood and mothers who did not grow up in affected areas in terms of their levels of differentiation of self and parental self-efficacy (PSE). The second aim was to identify and describe the parenting experiences of mothers who were exposed to military conflict in childhood. In Part 1 of the study, the sample included 120 mothers (half of whom reported on being exposed to ongoing military conflict in childhood). Findings showed that mothers exposed to ongoing military conflict in childhood reported lower levels of differentiation of self and PSE than their counterparts. In Part 2, 10 mothers who were exposed to ongoing military conflict as children were interviewed about their experience as parents and their PSE. Results indicated that the mothers felt their childhood experiences affected their parenting and PSE negatively, resulting in anxiety, difficulty dealing with stress and sometimes posttraumatic symptoms as well as parental patterns of overprotectiveness, separation anxiety and intergenerational transmission of anxiety. The results highlight the consequences of exposure to ongoing military conflict during childhood on levels of differentiation of self and parenting practices.

Depressive Symptoms Mediate the Relationship between Emotional Cutoff and Type 2 Diabetes Mellitus.

BACKGROUND: Differentiation of self is a family systems construct defined as the ability to balance intimacy and autonomy and to separate instinctually driven emotional reactions and thoughtfully considered goal-directed functioning. In theory, low differentiation of self is reflected by four components: a low tendency to take an I-position in relationships (i.e., to own one's thoughts and feelings); emotional cutoff from others; a greater tendency to fuse with others; and a tendency towards emotional reactivity. Low differentiation of self is associated with anxiety and depression, which are risk factors for type 2 diabetes mellitus. The current study examines the relationship between differentiation of self and type 2 diabetes mellitus. METHOD: Individuals with type 2 diabetes mellitus (N = 107) and healthy individuals (N = 145) completed the Differentiation of Self Inventory-Revised (DSI-R), the State-Trait Anxiety Inventory (STAI), and the Beck Depression Inventory (BDI-II). RESULTS: Compared with healthy individuals, participants with type 2 diabetes had more severe depressive symptoms, higher levels of emotional cutoff, and a lower tendency to take an I-position, but had similar levels of trait anxiety, emotional reactivity, and fusion with others (factor analysis revealed these factors were not separable in the current sample and thus were merged into a single construct). Importantly, the severity of depressive symptoms mediated the relationship between emotional cutoff and being in the type 2 diabetes study group rather than the healthy group. CONCLUSION: These findings suggest a new perspective on the role of psychological patterns in type 2 diabetes mellitus development and progression.

Differentiation of Self and Dyadic Adjustment in Couple Relationships: A Dyadic Analysis Using the Actor-Partner Interdependence Model.

Bowen's multigenerational theory provides an account of how the internalization of experiences within the family of origin promotes development of the ability to maintain a distinct self whilst also making intimate connections with others. Differentiated people can maintain their I-position in intimate relationships. They can remain calm in conflictual relationships, resolve relational problems effectively, and reach compromises. Fusion with others, emotional cut-off, and emotional reactivity instead are common reactions to relational stress in undifferentiated people. Emotional reactivity is the tendency to react to stressors with irrational and intense emotional arousal. Fusion with others is an excessive emotional involvement in significant relationships, whilst emotional cut-off is the tendency to manage relationship anxiety through physical and emotional distance. This study is based on Bowen's theory, starting from the assumption that dyadic adjustment can be affected both by a member's differentiation of self (actor effect) and by his or her partner's differentiation of self (partner effect). We used the Actor-Partner Interdependence Model to study the relationship between differentiation of self and dyadic adjustment in a convenience sample of 137 heterosexual Italian couples (nonindependent, dyadic data). The couples completed the Differentiation of Self Inventory and the Dyadic Adjustment Scale. Men's dyadic adjustment depended only on their personal I-position, whereas women's dyadic adjustment was affected by their personal I-position and emotional cut-off as well as by their partner's I-position and emotional cut-off. The empirical and clinical implications of the results are discussed.

La teoría multigeneracional de Bowen (1978) ofrece una explicación de cómo la internalización de experiencias dentro de la familia de origen promueve el desarrollo de la capacidad para mantener un yo diferenciado y a su vez conectarse de forma íntima con otras personas. Las personas diferenciadas pueden mantener su posición del yo en las relaciones amorosas. Pueden mantener la calma en relaciones conflictivas, resolver problemas relacionales eficazmente y llegar a acuerdos. En cambio, la fusión con los demás, el distanciamiento emocional y la sensibilidad emocional son reacciones comuntes al estrés relacional en las personas indiferenciadas. La sensibilidad emocional es la tendencia a reaccionar a factores desencadentes de estrés con excitación emocional irracional e intensa. La fusión con los demás es una implicación emocional excesiva en las relaciones significativas, mientras que el distanciamiento emocional es la tendencia a controlar la ansiedad relacional mediante la distancia física y emocional. Este estudio se basa en la teoría de Bowen, comenzando desde la suposición de que la adaptación diádica puede verse afectada tanto por la diferenciación del yo de un integrante de la pareja (efecto actor) como por la diferenciación del yo de su pareja (efecto pareja). Utilizamos el modelo de interdependicia actor-pareja (Cook & Kenny, 2005) para estudiar la relación entre la diferenciación del yo y la adaptación diádica en una muestra de conveniencia de 137 parejas italianas heterosexuales (datos diádicos, no independientes). Las parejas contestaron la "Encuesta sobre la diferenciación del yo" (Differentiation of Self Inventory, Skowron & Schmitt, 2003) y la "Escala de adaptación diádica" (Dyadic Adjustment Scale, Spanier, 1976). La adaptación diádica de los hombres dependió solo de su posición personal del yo, mientras que la adaptación diádica de las mujeres estuvo afectada por su posición personal del yo y el distanciamiento emocional así como por la posición del yo y el distanciamiento emocional de su pareja. Se debaten las consecuencias empíricas y clínicas de los resultados.

Differentiation of self and trait anxiety: A cross-cultural perspective.

Cultural differences are likely to affect the ability to deal with anxiety. We investigated this issue among four cultural groups-Germans and Italians (Europeans living in South Tyrol, Italy), Jews and Arabs (Israelis)-in terms of their levels of differentiation of self, trait anxiety and somatic symptoms. We also examined the relationship of differentiation of self to trait anxiety and somatic symptoms. The sample consisted of 824 students: 387 Israelis (mean age 23.6) and 437 Europeans (mean age 22.3). Israeli participants reported lower levels of trait anxiety than European students. Jewish students reported lower trait anxiety than Arab students (mean difference = -.14, p < .009), while there was no difference between German and Italian students (mean difference = .03, p > .99). Jews reported a significantly lower level of emotional cutoff than Arabs (mean difference = -.45, p < .001), and Germans reported a significantly lower level of emotional reactivity than Italians (mean difference = .29, p < .001). Emotional reactivity and I-position predicted all participants' trait anxiety. On the whole, results point to the importance of examining differentiation of self when trying to reduce trait anxiety, as well as some important cultural differences.

Humility, Relational Spirituality, and Well-being among Religious Leaders: A Moderated Mediation Model.

Prior research has demonstrated positive associations between general humility and well-being, and posited a protective effect for intellectual humility against maladjustment among religious leaders. We tested a model that extended findings on general humility to include intellectual humility among religious leaders (N = 258; M age = 42.31; 43% female; 63.7% White; 91.9% Christian affiliation). We observed a positive general humility-well-being association. Contrary to expectations, we observed risk effects for religion-specific intellectual humility. Our findings also point to the possibility that these risk effects might be attenuated by the integration of high levels of general and intellectual humility.

Testing a model of codependency for college students in Taiwan based on Bowen's concept of differentiation.

The purpose of this study was to test a model of codependency based on Bowen's concept of differentiation for college students in Taiwan. The relations between family-of-origin dysfunction, differentiation of self, codependency traits and related symptoms including low self-esteem, relationship distress and psychological adjustment problems were examined. Data were collected from 567 college students from 2 large, urban universities in northern Taiwan. Results indicated a significantly negative relationship between levels of codependency and self-differentiation and that self-differentiation partially mediated the relationship between family-of-origin dysfunction and codependency. The implications of these findings for counselling Taiwanese college students who experience codependency traits and related symptoms as well as suggestions for future research are discussed.

The Roles of Fathers' Posttraumatic Stress Symptoms and Adult Offspring's Differentiation of the Self in the Intergenerational Transmission of Captivity Trauma.

OBJECTIVES: This prospective study aims to assess the role of fathers' posttraumatic stress disorder (PTSD) symptoms (PTSS), the course of these symptoms over the years, and the relationship between these symptoms and their adult offspring's own PTSS and level of differentiation of self. METHOD: A sample of 123 Israeli father-child dyads (79 ex-prisoners of war [ex-POWs] dyads and a comparison group of 44 veterans' dyads) completed self-report measures. The fathers participated in 2 waves of measurements (1991 and 2008), while the offspring took part in 2013-2014. RESULTS: Increase in the fathers' PTSS over the years was related to high levels of his offspring's PTSS. Among ex-POWs' offspring, self-differentiation mediated the association between the father's PTSS and offspring's PTSS. Thus, a greater increase in the ex-POWs' PTSS over time was correlated to lower levels of the offspring's self-differentiation, which in turn was correlated to higher rates of PTSS. CONCLUSION: Veterans' PTSS as well as offspring's self-differentiation are mechanisms of the intergenerational transmission of captivity trauma.

Is committed desire intentional? A qualitative exploration of sexual desire and differentiation of self in couples.

The question of what heightens or diminishes sexual desire has long been a passionate theme across cultures in literature, arts, media, and medicine. Yet, little research has been conducted to determine what affects level of desire within couples. The degree of differentiation of self has been suggested as an important variable in shaping partners' level of desire. Through a qualitative analysis of dyadic couple interviews, this study provides an account of characteristics, processes, and trajectories of sexual desire and differentiation in 33 heterosexual couples of varying ages and relationship duration. Factors associated with high desire were change and autonomy, whereas conflict and children were reported to be desire-diminishing factors. Innovation, sharing, autonomy, and effort emerged as desire-promoting strategies, while fostering personal interests, investing in a positive connection, and enhancing personal integrity were identified as couples' strategies to promote and preserve differentiation of self. The results also shed light on couples' perceptions of whether and how sexual desire changes over the course of the relationship and challenge common cultural assumptions about desire in committed relationships-namely the myth that the only authentic expression of desire is that which occurs spontaneously and without intention and planning. Implications for couple therapy are discussed.

Correlates of female sexual functioning: adult attachment and differentiation of self.

INTRODUCTION: Female sexual functioning is affected by a range of factors including motivation, psychological well-being, and relationship issues. In understanding female sexual dysfunction (FSD), there has been a tendency to privilege diagnostic and medical over relationship issues. AIM: To investigate the association between women's experience of intimacy in close relationships-operationalized in terms of attachment and degree of differentiation of self-and FSD. METHODS: Two hundred thirty sexually active Australian women responded to an invitation to complete a set of validated scales to assess potential correlates of sexual functioning. MAIN OUTCOME MEASURES: The Female Sexuality Function Index, the Experiences in Close Relationships Scale, the Differentiation of Self Inventory, as well as a set of study-specific questions were subject to hierarchical multiple regression analyses. RESULTS: Relational variables of attachment avoidance and to a lesser degree, attachment anxiety were associated with FSD. Participants with lower levels of differentiation of self were more likely to report sexual difficulties. The inability to maintain a sense of self in the presence of intimate others was the strongest predictors of sexual problems. A history of sexual abuse in adulthood and higher levels of psychological distress were also associated with sexual difficulties. CONCLUSIONS: The findings provide support for a relational understanding of female sexual functioning. Attachment avoidance, attachment anxiety, and degree of differentiation of self are shown to be associated with sexual difficulties. The findings support the need to focus on relational and psychological factors in women's experience of sex.

The relationships between stressful life events during childhood and differentiation of self and intergenerational triangulation in adulthood.

This study examined the relationships between stressful life events in childhood and differentiation of self and intergenerational triangulation in adulthood. The sample included 217 students (173 females and 44 males) from a college in northern Israel. Participants completed the Hebrew versions of Life Events Checklist (LEC), Differentiation of Self Inventory-Revised (DSI-R) and intergenerational triangulation (INTRI). The main findings were that levels of stressful life events during childhood and adolescence among both genders were positively correlated with the levels of fusion with others and intergenerational triangulation. The levels of positive life events were negatively related to levels of emotional reactivity, emotional cut-off and intergenerational triangulation. Levels of stressful life events in females were positively correlated with emotional reactivity. Intergenerational triangulation was correlated with emotional reactivity, emotional cut-off, fusion with others and I-position. Findings suggest that families that experience higher levels of stressful life events may be at risk for higher levels of intergenerational triangulation and lower levels of differentiation of self.

The role of emotional dysregulation in the association between family-of-origin conflict and romantic relationship maintenance.

Family-of-origin systems are consequential for the emotional well-being of offspring. These influences are likely to last into adulthood, affecting adult children's romantic relationships. The mechanisms by which family-of-origin environments influence adult romantic relationships are not fully understood. In a sample of 118 different-sex couples, we tested the effects of negative family-of-origin conflict on adult offspring's provision of relationship maintenance to their romantic partner using structural equation modeling. We evaluated emotional dysregulation as a mediator of this effect, using two measures of emotional dysregulation. Results from structural models demonstrated a negative effect of family-of-origin conflict on the provision of relationship maintenance via higher levels of emotional dysregulation. Our results highlight emotional self-regulation as a valuable intervention point for couple therapists.

Exploring the personality and relationship factors that mediate the connection between differentiation of self and phubbing.

One of the family patterns crucial for mental and physical well-being is differentiation of self. In this study, our aim was to investigate its impact on the phenomenon of phubbing-where individuals prioritize smartphones over in-person interactions. The prevalence of phubbing behavior has risen substantially in tandem with the increased adoption of smartphones. The study investigated familial, interpersonal, and personal factors that could potentially contribute to the escalation of phubbing behaviors. It was hypothesized that differentiation of self would be associated with phubbing through the mediation of fear of missing out, romantic relationship satisfaction, and loneliness in intimate relationships. We also expected gender differences in the study variables. A sample of 431 young adults, with an average age of 29 (M = 29.05, SD = 9.14), completed the DSI-R, Phubbing, FoMO, ENRICH, and LIRS questionnaires online. Results indicated that fear of missing out mediated the relationship between three dimensions of differentiation of self-emotional reactivity, emotional cutoff, and fusion with others-and phubbing behavior. However, the expected mediation by romantic relationship satisfaction and loneliness in intimate relationships did not reach significance, although these variables were found to be associated with differentiation of self. Women reported higher levels of phubbing behavior, emotional reactivity, and fusion with others, whereas men reported higher levels of I-position. We conclude that fear of missing out may serve as a catalyst, triggering anxiety in individuals, which in turn drives them to adopt phubbing as a coping mechanism. Moreover, individuals with lower levels of differentiation of self appear to be at increased risk of engaging in phubbing behaviors through the mediation of fear of missing out.

Maternal Differentiation of Self and Toddlers' Sleep: The Mediating Role of Nighttime Involvement.

Good sleep is essential for optimal development and adaptive functioning. Hence, identifying the factors that shape sleep quality is important. Based on the transactional model of sleep development and drawing on Bowen's concept of differentiation of self (DoS), the present study examined the interrelations between sleep-related parental behavior, child's sleep quality, and mothers' DoS. A community sample of 130 mothers of 24- to 36-month-old children completed the DoS instrument and sleep questionnaires. Lower maternal DoS levels were associated with higher parental sleep-related involvement, both at bedtime and through the course of the night. Using structural equation modeling (SEM), a path analysis model indicates that maternal sleep-related involvement functions as a mediator through which the differentiation of self is related to the sleep characteristics of toddlers. As the links between parenting practices and child sleep reflect bi-directional associations, the conclusion that can be drawn from the present data is that relational aspects, such as those defined and measured by the construct of DoS, contribute to sleep-wake regulation beyond infancy. The data suggest that this construct should be considered in intervention research.

Personality and Family Risk Factors for Poor Mental Well-Being.

There is evidence that differentiation of self (DoS) contributes to the regulation of emotions at a young age, resulting in reduced anxiety and improved mental well-being. However, there is little evidence of the relationships between these four dimensions (DoS, self-regulation, anxiety, and mental well-being), or of the potential mediating role of self-regulation and anxiety. Our primary goal was therefore to consider the links between DoS, self-regulation, anxiety, and mental well-being. It was hypothesized that DoS (emotional reactivity, I-position, emotional cutoff, fusion with others) will be positively associated with mental well-being through the mediation of self-regulation (promotion-focused, prevention-focused) and anxiety. The study included 460 participants with a mean age of 41.18 (SD = 14.97, range = 19-60). Of them, 224 (48.7%) were women. Participants filled out four questionnaires: the Differentiation of Self Inventory-Revised, General Regulatory Focus Measure, the anxiety scale from DASS-21, and the Warwick-Edinburgh Mental Well-being Scale. The findings showed that emotional cutoff positively predicted prevention and anxiety, but did not predict promotion. In addition, promotion positively predicted mental well-being. Finally, promotion mediated the relationship between I-position and mental well-being. The results indicate that well-differentiated individuals function optimally and enjoy good quality of life.
