Abstract
Objective: The present study is a validation of the English language version of the Affect Integration Inventory short form with 27-items (AII-SF-27). Assessments of external and nomological net validity include variables with an established association to the affect integration construct (interpersonal problems and personality disorder criteria). Additionally, the study examines previously unexplored associations between work-related variables and AII-SF-27 scales, with an aim of assessing the utility of the affect integration construct in an occupational context. Method: This study used archival data from a non-clinical, British sample (N=398) who completed a test battery of self-report instruments. We conducted analyses of reliability, assessment of internal structure by confirmatory factor analyses, and evaluation of external, convergent, discriminant, and nomological net validity by examining associations to interpersonal problems, personality disorder criteria, work engagement, leader-member exchange, work-related stress, and burnout. Results: Reliability analyses yielded generally high internal consistency for the AII-SF-27. CFAs showed that a pre-hypothesized bifactorial structure provided the best fit, which is consistent with the conceptualization of the affect integration concept. Associations to external variables were generally in line with our expectations, supporting the external and construct validity of the AII-SF-27. Conclusion: The present study supports the reliability and validity of the AII-SF-27, showing satisfactory and theoretically sound internal structure and associations with external criteria. Furthermore, our findings support the utility of AII-SF-27 within numerous different contexts, including the occupational. We encourage future research to further examine this potential.
