Table_1_Psychometric Properties of a Cultural Adapted Version of the Assessment of Identity Development in Adolescence in Panama.docx

The Assessment of Identity Development in Adolescence (AIDA) is a self-report instrument to detect pathological development of Identity. In Panamá, psychometric instruments for assessment of psychopathology in adolescence are lacking. Our aim was to develop a valid and reliable version of the AIDA Inventory for Panamanian Population. AIDA was adapted to Spanish considering cultural aspects of Panamanian population. Two pilot tests were performed prior to main test to assess item-total correlation at subscale, primary scale and total scale levels and internal consistency at subscale level. A mixed sample of students and PD patients (N = 315) completed the AIDA inventory, the “Strength and Difficulties Questionnaire” and “Defense Style Questionnaire−40.” AIDA was retested in a sub sample from school population (n = 98). The Structured Clinical Interview for Axis II Disorders was used for diagnosis of personality disorders in the patient sample (n = 25). Psychometric properties were tested to assess internal consistency, reliability, factorial validity, convergent validity, and criterion validity. AIDA Panama showed excellent internal consistency for the total scale Identity Diffusion with Cronbach's α:0.94 and a retest reliability of 0.84. A Bifactorial CFA was modeled to assess the dimensionality of the inventory. The proportion between OmegaH and Omega at total scales 96% of the variance is explained by a general factor. Furthermore, the Explained Common Variance for the General Factor is 73% supporting unidimensionality. In line with theory, AIDA total scale showed a high positive correlation (r = 0.67) with Total Difficulties scale and high positive correlation (r = 0.71) with Immature Defense scale. The AIDA total score differed highly significant (p = 0.000) between the patient sample and the students with a large effect size (d = 1.02).ConclusionThe adaptation and validation of AIDA for Panamanian adolescent population was successful with good psychometric properties and significant correlations with related psychopathological constructs. AIDA showed high clinical validity by providing a valid discrimination between the school sample and a diagnosed PD sample, in line with the assumption that impaired identity functioning is at the core of personality disorders, especially in adolescence.

《青少年身份发展评估》（AIDA）系一种自我报告式工具，旨在探测身份发展的病理状态。在巴拿马，缺乏用于评估青少年心理病理学的心理测量工具。本研究旨在为巴拿马人群开发一个有效且可靠的AIDA量表版本。考虑到巴拿马人群的文化特性，AIDA量表被翻译成西班牙语。在正式测试之前，进行了两次预测试，以评估子量表、一级量表和总量表层面的项目总分相关以及子量表层面的内部一致性。一组混合样本，包括学生和PD患者（N = 315）完成了AIDA量表、‘力量与困难问卷’和‘防御风格问卷−40’。AIDA量表在学校人群的子样本（n = 98）中进行了重测。结构化临床访谈用于对受试者样本（n = 25）中的个性障碍进行诊断。通过测试内部一致性、可靠性、因子效度、收敛效度和标准效度来评估心理测量特性。AIDA巴拿马版在身份扩散总量表上表现出优异的内部一致性，Cronbach's α系数为0.94，重测可靠性为0.84。通过构建双因素CFA模型来评估量表的维度。总量表中，96%的方差由一个一般因素解释，而一般因素的共同解释方差为73%，支持单维性。与理论一致，AIDA总量表与总困难量表显示出高度的正相关（r = 0.67），与不成熟防御量表也显示出高度的正相关（r = 0.71）。AIDA总评分在患者样本与学生样本之间差异显著（p = 0.000），具有较大的效应量（d = 1.02）。结论：AIDA量表在巴拿马青少年人群中的本土化与验证取得了成功，具有良好的心理测量特性和与相关心理病理结构的显著相关性。AIDA通过在校园样本与确诊的PD样本之间提供有效的区分，显示出高度的临场效度，这与身份功能受损是人格障碍核心，尤其是在青少年中的假设相吻合。
