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

Differentiation of self and relationship attachment, quality, and stability: A path analysis of dyadic and longitudinal data from Spanish and U.S. couples

OBJECTIVES

In the current study, we examined the relationship between differentiation of self (DoS) and key relationship functioning variables among couples. This is the first study to test such relationships using a cross-cultural longitudinal approach (i.e., samples from Spain and the U.S.) while controlling for stressful life events-a key theoretical construct in Bowen Family Systems Theory.

METHODS

A sample of 958 individuals (n = 137 couples from Spain, and n = 342 couples from U.S.) was used in cross sectional and longitudinal models to analyze the effects of a shared reality construct of DoS on anxious attachment, avoidant attachment, relationship stability, and relationship quality while considering gender and culture.

RESULTS

Our cross-sectional results indicated that men and women from both cultures experienced an increase in DoS over time. DoS predicted increased relationship quality and stability and decreased anxious and avoidant attachment in U.S. participants. Longitudinally, DoS predicted increased relationship quality and decreased anxious attachment for Spanish women and men, while it predicted greater relationship quality and stability and decreased anxious and avoidant attachment of U.S. couples. Implications of these mixed findings are discussed.

CONCLUSIONS

Higher levels of DoS are linked with a better couple relationship across time, despite varying levels of stressful life events. Although some cultural differences regarding the links between relationship stability and avoidant attachment exist, this positive link between differentiation and the couple relationship is mostly consistent across the U.S. and Spain. The implications and relevance for integration into research and practice are discussed.

Differentiation of self and its relationship with marital satisfaction and parenting styles in a Spanish sample of adolescents' parents

The present study aims to test some of the assumptions of Bowen's Family Systems Theory, specifically, to assess the relationships between differentiation of self (DoS), marital satisfaction and parenting styles, as well as the gender differences in these variables in a Spanish sample. The sample includes 140 Spanish non-single adults, over 30 years old, who have at least one adolescent son or daughter, aged between 12 and 19 years old. The instruments used were a sociodemographic questionnaire, the Differentiation of Self Scale, the Warmth Scale-Parents, the Rules and Demands Scale-Parents and the Satisfaction subscale of the Dyadic Adjustment Scale. The results show DoS is related to marital satisfaction, and parenting styles' dimensions. Regarding gender, women show higher emotional reactivity and warmth-communication than men do. Furthermore, marital satisfaction mediates the relationship between DoS and parental warmth-communication, criticism-rejection and inductive form. Finally, implications for clinical practice and future research are discussed.

Psychometric study of the differentiation of self scale-revised in a sample of Spanish adults

This study analyzes the psychometric properties of the Differentiation of Self Scale-Revised (DSS-R), an instrument assessing the differentiation of the self of Spanish adults through the dimensions I Position, Emotional Reactivity, Fusion with Others and Emotional Cutoff, and of a new dimension, Dominance over Others. In Study 1, carried out with 1445 subjects, exploratory factor analysis was performed with one half of the participants, and confirmatory factor analysis with the other, comparing the five-factor and bifactor models. In Study 2, examining convergent validity, 180 subjects participated and completed the revised scale and the Differentiation of Self Inventory-Revised. Studies 3 and 4 verified concurrent validity, with 401 subjects completing the DSS-R and the State-Trait Anxiety Inventory in Study 3, and 170 subjects completing the DSS-R and the Couple Assertion Questionnaire in Study 4. Adequate internal consistency indices and evidence of construct, convergent and concurrent validity were found. The use of the DSS-R is recommended for assessing the differentiation of the self in the Spanish population.

Differentiation of self: A scoping review of Bowen Family Systems Theory's core construct

Bowen Family Systems Theory's central construct, differentiation of self (DoS), is one of the most recognized constructs to systemic researchers and psychology professionals. The present study reviewed the available evidence on DoS from the inception of the construct until July 31, 2020. A scoping review was conducted and a total of 295 primary studies were eligible for inclusion. Literature was categorized according to the hypotheses postulated by Bowen regarding: the associations between DoS and psychological and health outcomes and how DoS stability and similarity in partner levels operate within family systems. Descriptive data regarding studies on the measurement of DoS and in the area of psychotherapy were also compiled. Results revealed that there is ample support for DoS as a predictor of psychological health and marital quality, and that there are positive associations between DoS and better physical health and intergenerational relationships. Results of this review show that there continue to be underexplored hypotheses and a paucity of longitudinal or causal research designs to test the stability of DoS, the intergenerational transmission of DoS, and the efficacy of clinical interventions in modifying DoS to promote optimal well-being. Recommendations and next steps for researchers and practitioners are outlined.

Adult Attachment, Differentiation of Self, and Relationship Satisfaction in Lesbians and Gay Men

We examined adult attachment styles, differentiation of self, and relationship satisfaction in a sample of 298 Italian lesbians (48%) and gay men (52%), all of whom were ages 19–71 years (M = 36.1; SD = 11.8) and in a couple relationship for at least six months. Participants were recruited via the Internet and completed a web-based survey. We tested the hypotheses that attachment insecurity and differentiation of self would predict relationship satisfaction, as well as that differentiation of self would mediate the relationship between adult attachment and relationship satisfaction. Results supported the hypotheses, thus indicating that attachment insecurity and differentiation of self were correlated with and predicted relationship satisfaction. Furthermore, results supported the hypothesized mediating role of differentiation of self. Finally, results indicated that younger participants, lesbians, and participants in civil unions reported higher levels of relationship satisfaction. Implications for counselors and therapists working with LG populations are discussed.
