本文提出了一种评估非西方野外环境下心理健康测量的信度和效度的方法。我们用我们开发的阿乔利心理社会评估工具（APAI）的例子来描述这种方法，该工具旨在评估乌干达北部受战争影响的青少年中的抑郁（两组，par和kumu），焦虑（ma）和行为问题（kwo maraco）。为了在缺乏传统金标准的情况下检验这一措施的标准有效性，我们从定性数据中获得了当地综合征术语，并使用土著居民对这些综合征的自我报告作为确定病例的参考点。信度测试采用标准测试-重测试和内部测试方法。抑郁样综合征的各分量表得分均表现出较强的内部信度，α =0.84 ~ 0.87。焦虑（0.70）、行为问题（0.83）和亲社会态度和行为（0.70）分量表的内部信度较好。除行为问题量表和亲社会量表外，大部分量表的信度和重测信度均较好。在所有三种抑郁样综合征的数据中，自我报告的病例与非病例在局部综合征项上相应的APAI问题量表得分的平均差异显著，但在焦虑样综合征ma - lwor或行为问题wo - maraco中没有这种差异。
This paper presents an approach for evaluating the reliability and validity of mental health measures in non-Western field settings. We describe this approach using the example of our development of the Acholi Psychosocial Assessment Instrument (APAI), which is designed to assess depression-like (two tam, par and kumu), anxiety-like (ma lwor) and conduct problems (kwo maraco) among war-affected adolescents in northern Uganda. To examine the criterion validity of this measure in the absence of a traditional gold standard, we derived local syndrome terms from qualitative data and used self reports of these syndromes by indigenous people as a reference point for determining caseness. Reliability was examined using standard test-retest and inter-rater methods. Each of the subscale scores for the depression-like syndromes exhibited strong internal reliability ranging from α =0.84 to 0.87. Internal reliability was good for anxiety (0.70), conduct problems (0.83), and the pro-social attitudes and behaviors (0.70) subscales. Combined inter-rater reliability and test-retest reliability were good for most subscales except for the conduct problem scale and prosocial scales. The pattern of significant mean differences in the corresponding APAI problem scale score between self-reported cases vs. noncases on local syndrome terms was confirmed in the data for all of the three depression-like syndromes, but not for the anxiety-like syndrome ma lwor or the conduct problem kwo maraco.
