ABSTRACT=ObjectiveThe aim of the current study was to adapt the Adult Disorganized Attachment Scale (ADA) to Persian and to examine its psychometric properties.MethodThe study was conducted with 202 participants, including 124 female (61.4%), who were students at Kermanshah University of Medical Sciences, aged 17–36 years. The Experience in Close Relationships measure was used to assess convergent validity, while the Sadism Scale and Shutdown Dissociation Scale were used to evaluate criterion validity. The reliability using Cronbach’s alpha coefficient, convergent validity, and construct validity using confirmatory factor analysis were examined. The collected data were analyzed in SPSS v.25 and LISREL 8.8 applications.ResultsThe scale demonstrated strong reliability (α = 0.82) and good convergent validity, with positive correlations to Shutdown Dissociation, Anxious and Avoidant Attachment, and Sadism (p < 0.05). Confirmatory Factor Analysis supported its structural validity with excellent fit indexes (χ2/df = 1.44, RMSEA = 0.047, CFI = 0.98, GFI = 0.96).ConclusionThis Persian version of the ADA can be considered a valid and reliable scale, which is a short and practical tool that can be used in clinical and research settings in Iran.
