Structural model for predicting marital satisfaction in young couples based on behavioral activation/ inhibition systems; the mediating role of attachment styles

Introduction: Marital satisfaction serves as a fundamental predictor of stability and well-being within individuals' lives and families. Aim: This study aims to develop a structural model that predicts marital satisfaction among young couples by examining the interplay between behavioral activation/inhibition systems and attachment styles. Method: The current study was a description of structural equations. A sample of 370 young couples in Tehran during the year 2021 was selected using convenience sampling. Data were collected through demographic questionnaires, Enrich's Marital Satisfaction Questionnaire (1998), the Behavioral Activation/ Inhibition Scale (1994), and the Adult Attachment Scale (2015). Path analysis was conducted using SPSS version 25 and LISREL version 8.8 for data analysis. Results: The results of the path analysis revealed several significant findings. Firstly, the inhibition system demonstrated a direct negative impact on marital satisfaction (ß=-0.16, P<0.05), along with ambivalent insecure attachment (ß=-0.42, P<0.01) and avoidant insecure attachment (ß=-0.19, P<0.05). Conversely, secure attachment displayed a direct and positive effect on marital satisfaction (ß=0.26, P<0.01). Furthermore, the inhibition system exhibited a direct and positive influence on avoidant insecure attachment (ß=0.18, P<0.01) and ambivalent insecure attachment (ß=0.19, P<0.01). Additionally, the activation system had a direct positive effect on secure attachment (ß=0.28, P<0.05) but a direct negative effect on avoidant attachment (ß=-0.30, P<0.01). Conclusion: The results of the study underscore the direct predictive role of the activation/inhibition system in marital satisfaction, with attachment styles playing an indirect role. Therefore, therapists should consider these variables to enhance satisfaction levels in couples
