Abstract

Self-expansion involves growing oneself through new activities and relationships. The Self-Expansion Questionnaire (SEQ) is grounded in the self-expansion model, which conceptualizes it as a multidimensional process. This study aimed to confirm the factor structure of the SEQ and adapt it within an Iranian cultural context, while also examining the role of demographic variables in predicting self-expansion. A sample of 194 participants, selected through simple random sampling, responded to SEQ items. Cronbach's alpha coefficient for total SEQ was 0.92. Results of CFA supported the factor structure of SEQ [RMSEA = 0.08, GFI = 0.88, and CFI = 0.92], indicating a good model fit and significant item loading. All items except Q7 showed strong correlations. Stepwise regression showed that among demographic variables, only duration of marriage was significant [F(1, 125) = 4.511, p = .036] and predicted lower SEQ. These findings provide insights into the cultural adaptation of self-expansion in romantic relationships and highlight the need for future cross-cultural studies of relational dynamics.
