Validation of the Dimensions of Identity Development Scale (DIDS) Adapted for Parental Identity (DIDS-PI): Dimensions and Statuses Among Expectant and Current Parents

Abstract

The Dimensions of Identity Development Scale (DIDS) is a widely used measure aimed at assessing five identity processes (Exploration in Breadth, Commitment Making, Exploration in Depth, Identification with Commitment and Ruminative Exploration). Combining individuals’ scores across these processes allows the identification of six distinct identity statuses. Originally developed in the context of nonspecific plans for the future, the scale was later adapted to examine specific identity-domains. The purpose of the current study was to adapt the DIDS to measure parental identity (DIDS-PI) and validate both its dimensions and clusters. Our sample included current (N = 360, 58.3% women, mean age = 34.7) and expectant (N = 171, 56.7% women, mean age = 30.7) Israeli parents, who completed DIDS-PI and a self-report Personal Growth questionnaire. Results demonstrated that the hypothesized five-dimensional model fit the data well for both groups. Cluster analysis further indicated that a six-cluster solution provided the best fit across groups. Personal Growth correlated with identity statuses among current parents, which supported the scale’s convergent validity. The findings suggest that the DIDS-PI is a reliable tool for assessing parental identity development in current parents, with preliminary evidence supporting its use among expectant parents, though further validation is needed.
