The aim of this study was to examine the impact of vulnerable attachment and childhood ‎trauma on ‎identity crisis in adolescents. This descriptive-correlational study was conducted ‎with 181 adolescents ‎selected through convenience sampling from schools in Aq Qala County. ‎Data were collected using the ‎Identity Crisis Questionnaire, the Vulnerable ‎Attachment Scale, and the Childhood Trauma ‎Questionnaire. The results of statistical analyses revealed that both vulnerable attachment and ‎‎childhood trauma had a significant positive relationship with identity crisis in adolescents. In ‎particular, ‎vulnerable attachment was found to be a predictor of identity crisis, and childhood ‎trauma significantly ‎contributed to the increase in identity crisis. Stepwise regression analysis ‎showed that these two ‎variables collectively accounted for 33.3% of the variance in identity ‎crisis. These findings highlight the ‎importance of early childhood experiences and attachment ‎relationships in the formation of identity ‎crisis in adolescents and can serve as a foundation for ‎designing psychological and preventive ‎interventions in this area.‎
