The Integration of Stressful Life Experiences Scale (ISLES) evaluates the ability to integrate stressful experiences into one's meaning system. This study aimed to validate ISLES for the Portuguese population, utilizing a sample of 242 adults who had lost a significant other. The sample was predominantly female, educated, married, or in consensual unions, and actively employed. Confirmatory factor analysis revealed a two-factor structure, consisting of 13 items, showing adequate local and global goodness-of-fit and supporting the proposed original structure. Convergent evidence based on internal structure was found for the two dimensions (Comprehensibility and Footing in the World). Regarding reliability, Cronbach’s alpha and McDonald's omega computed for each factor showed good internal consistency and the average inter-item correlation was considered satisfactory. This psychometric support for ISLES underscores its relevance in enhancing the knowledge of meaning-making processes in the Portuguese context.
