Affect integration is defined as the capacity to comprehend emotional experiences as meaningful and to convert this knowledge into well-adjusted motivation, communication and behavior. Thus, affect integration is considered essential for personal adjustment and well-being, and it has been operationalized through the Affect Integration Inventory. However, the validity of this questionnaire has been examined only in non-clinical respondents. Therefore, the purpose of this study was to investigate the psychometric properties of the questionnaire in a sample of patients with personality disorders (n = 87). The internal structure and consistency were addressed using Cronbach's alpha and confirmatory factor analysis. To determine aspects of convergent and discriminant validity, the correlations between the scores on the questionnaire and the scores on content-related questionnaires and scales were examined. Finally, scores from the clinical respondents and existing data from a previously collected non-clinical sample (n = 157) were compared to evaluate the external validity. The overall results demonstrated satisfactory internal consistency, a consistent factor structure, and systematic patterns of convergent and discriminant validity. Additionally, the findings indicated that the instrument clearly differentiated the clinical sample from the non-clinical sample.
