Abstract
BACKGROUND: Lebanon is passing through an economic crisis leading to a decreased monthly income within a couple and more couple's dissatisfaction. Furthermore, many studies postulate that the different types of attachment styles affect the romantic relationship experienced between adults. The main objectives of our study were to (1) validate the Toronto Alexithymia Scale (TAS) and Couple Satisfaction Index-4 (CSI-4) scales, and (2) assess the association between attachment styles and couple satisfaction and evaluate the mediating role of alexithymia in these associations. METHODS: This cross-sectional study involved 445 Lebanese participants (April-May 2021). A confirmatory factor analysis (CFA) was carried out using SPSS AMOS v.24 on the couple satisfaction index and Toronto alexithymia scales' items. A linear regression was conducted, taking the couple satisfaction index as the dependent variable. RESULTS: The CFA results of the CSI-4 scale indicated an excellent fit (χ(2)/df = 3.845/2 = 1.92, TLI = 0.992, RMSEA = 0.046 [95% CI 0.001-0.115] (pclose = 0.436) and CFI = 0.998). The CFA of the TAS indicated a good/acceptable fit (χ(2)/df = 422.31/132 = 3.2, TLI = 0.89, RMSEA = 0.07 [95% CI 0.063-0.078] (pclose < 0.001) and CFI = 0.91) (items 4 and 8 were removed due to low factor loading (< 0.4)). Being married and higher secure attachment style were significantly associated with more couple satisfaction, whereas older age, higher household crowding index, more alexithymia and mode depression were significantly associated with less couple satisfaction. In addition, alexithymia mediated the association between secure attachment style and couple satisfaction, between preoccupied attachment style and couple satisfaction and between dismissing attachment style and couple satisfaction. CONCLUSION: Couple's satisfaction is positively associated with secure attachment style. In addition, alexithymia plays a mediating role between couple's satisfaction and attachment styles. Upcoming studies should determine if other mental illnesses play a mediating role between attachment style and couple satisfaction.
