Adaptation and Validation of the Couple Resilience Inventory (CRI) in a Portuguese sample: The Portuguese Couple Resilience Inventory

Introduction: Several studies have proved that fostering resilience in couples when facing adversities plays a key role in intimate relationships. Aim: The aim of this study was to adapt and validate the Portuguese version of the Couple Resilience Inventory (CRI). Method: Data was collected from 336 individuals from the Portuguese general population, from 18 to 80 years (M = 35.38; SD = 15.36). We tested the internal structure of the CRI using confirmatory factor analysis (CFA) and also examined the reliability and construct validity. Results: The results supported the two-factor correlated structure of the original validation study: Positive Couple Resilience (PCR) and Negative Couple Resilience (NCR). The overall fit of the nested model was satisfactory. The internal consistency was high for both PCR (α = .920; ω = .919) and NCR (α = .860; ω = .862) CRI factors. Thus, both CRI factors showed adequate internal consistency, as indicated by the reliability coefficients and item-factor correlations. Evidence of convergent and divergent validity emerged via a hierarchical regression model that showed significant associations between couple resilience and dyadic coping factors. Conclusion: These findings provide evidence regarding the psychometric properties of the Portuguese version of the Couple Resilience Inventory.
