This study evaluated the validity and reliability of the Persian version of Positive Body Image among Adolescents Scale (PBIAS-P) in Tehran, Iran, in order to better understand adolescents' positive perceptions of their physical selves and the accompanying thoughts and emotions. This cross-sectional study was carried out involving adolescents from Tehran Province, Iran, in 2022. Both exploratory factor analysis and confirmatory factor analysis were performed in order to evaluate the construct validity of the PBIAS-P. Coefficient α, McDonald's omega, and intraclass correlation coefficients were also used to confirm the internal consistency of the scale. The findings indicate that three factors extracted from the PBIAS-P account for 50.1% of the total variance. The model fit is considered good based on cut points for various fit indices. All factors had values of coefficient α, McDonald's omega, and average interitem correlation above 0.73, 0.74, and .4, respectively. Also, test-retest reliability for three factors was acceptable. The PBIAS-P has acceptable validity and reliability in Iranian adolescents, making it useful for researchers, psychologists, and health care professionals.
本研究评估了青少年积极身体意象量表波斯语版（PBIAS-P）在伊朗德黑兰的有效性和可靠性，以便更好地了解青少年对自身身体的积极认知以及随之产生的想法和情绪。这项横断面研究于2022年在伊朗德黑兰省的青少年中开展。为评估PBIAS-P的结构效度，进行了探索性因素分析和验证性因素分析。还使用了系数α、麦克唐纳ω系数和组内相关系数来确认该量表的内部一致性。研究结果表明，从PBIAS-P中提取的三个因素占总方差的50.1%。基于各种拟合指数的切点，模型拟合被认为良好。所有因素的系数α、麦克唐纳ω系数和平均项目间相关性值分别高于0.73、0.74和0.4。此外，三个因素的重测信度是可接受的。PBIAS-P在伊朗青少年中具有可接受的效度和信度，这使其对研究人员、心理学家和医疗保健专业人员有用。
