The present study was conducted to examine the psychometric properties and gender invariance of the Iranian version of the Dimensions of Identity Development Scale (DIDS). A total of 1453 adolescents (50.8% female; 14-18 years old, mean = 15.48) participated in a cross-sectional study and completed the DIDS and the Youth Self-Report of behavior problems. The Confirmatory Factor Analysis supported the six-factor model of the DIDS, echoing past studies showing the original 5th factor (Exploration in Depth) being divided into Exploration in Depth and Reconsidering the Commitment. The invariance testing showed comparable measurement properties of the DIDS across males and females (strict measurement invariance). Further, behavior problems were associated positively with Ruminative Exploration and negatively with Commitment Making, Identification with Commitments, Exploration in Depth, and Reconsideration of Commitments, whereas the opposite was true for academic performance. A six-factor DIDS was shown to be a valid and reliable measure for the assessment of identity development dimensions among Iranian adolescents. Future studies in the Iranian context evaluating the identity clusters derived from identity dimensions and their gender differences are warranted.
本研究旨在检验伊朗版身份发展维度量表（DIDS）的心理测量特性和性别不变性。共有 1453 名青少年（50.8%为女性；14-18 岁，平均年龄=15.48）参与了一项横断面研究，完成了 DIDS 和青少年自我报告行为问题。验证性因素分析支持 DIDS 的六因素模型，与过去的研究结果一致，表明原始的第 5 个因素（深入探索）被分为深入探索和重新考虑承诺。不变性检验表明，DIDS 在男性和女性之间具有可比的测量特性（严格的测量不变性）。此外，行为问题与沉思探索呈正相关，与承诺制定、对承诺的认同、深入探索和重新考虑承诺呈负相关，而学业成绩则相反。六因素 DIDS 被证明是一种有效的、可靠的方法，可用于评估伊朗青少年身份发展维度。在伊朗背景下，未来的研究评估从身份维度中得出的身份群集及其性别差异是有必要的。
