本研究的目的是完善一个维度的量表，用于测量非洲青年的心理社会适应使用项目反应理论（IRT）。来自定性数据的60项量表管理667受战争影响的青少年（55%女性）。探索性因素分析（EFA）确定的拟合优度指数的基础上的项目的维度。载荷小于0.4的项目被丢弃。使用验证性因素分析（CFA）来确认量表在EFA下的维度。项目歧视和难度估计使用分级反应模型，每个分量表使用加权最小二乘均值和方差。通过每个分量表的IRT评分（θ）与功能障碍评分之间的相关性来检验预测效度。所有模型均采用拟合优度和比较拟合指数进行评估。费雪信息曲线检查项目精度在不同的潜在范围内的每一个特质。最初的量表项目进行了优化，并重新配置成一个强大的41个项目的规模，非洲青年心理社会评估（AYPA）。完善的分量表评估内化和外化问题，亲社会的态度/行为和身体投诉没有医疗原因。AYPA是对非洲青年情绪和行为问题的精细维度评估，具有良好的心理测量特性。建议在其他培养物中进行验证研究。
This study aimed to refine a dimensional scale for measuring psychosocial adjustment in African youth using item response theory (IRT). A 60-item scale derived from qualitative data was administered to 667 war-affected adolescents (55% female). Exploratory factor analysis (EFA) determined the dimensionality of items based on goodness-of-fit indices. Items with loadings less than 0.4 were dropped. Confirmatory factor analysis (CFA) was used to confirm the scale's dimensionality found under the EFA. Item discrimination and difficulty were estimated using a graded response model for each subscale using weighted least squares means and variances. Predictive validity was examined through correlations between IRT scores (θ) for each subscale and ratings of functional impairment. All models were assessed using goodness-of-fit and comparative fit indices. Fisher's Information curves examined item precision at different underlying ranges of each trait. Original scale items were optimized and reconfigured into an empirically-robust 41-item scale, the African Youth Psychosocial Assessment (AYPA). Refined subscales assess internalizing and externalizing problems, prosocial attitudes/behaviors and somatic complaints without medical cause. The AYPA is a refined dimensional assessment of emotional and behavioral problems in African youth with good psychometric properties. Validation studies in other cultures are recommended.
