很少有强迫症（OCD）的治疗结果研究使用行为回避测试（bat）来评估症状学的变化，可能是因为对一种具有广泛变化症状的疾病构建这样的测试很困难。少数几项研究检测了bat治疗强迫症的心理测量特性，发现了有效性的混合证据，但治疗敏感性很好。本研究提出了多步骤/多任务BAT的心理测量结果，评估了完成步骤的百分比、主观焦虑、全局回避和仪式。该测量方法被用于50名被诊断为强迫症的患者，他们的症状差异很大。根据效应量计算，BAT表现出良好的收敛效度和发散效度，以及治疗敏感性。在心理测试中，步数、焦虑水平、回避和仪式的综合得分也表现良好。提出了降低评分复杂性的策略，以及几个BAT任务的例子，使研究人员能够采用这种行为测量。
Few treatment outcome studies of Obsessive Compulsive Disorder (OCD) have employed Behavioral Avoidance Tests (BATs) to assess changes in symptomatology, probably because of the difficulty of constructing such tests for a disorder which has widely varying symptoms. The few studies that have examined the psychometric properties of BATs for OCD have found mixed evidence for validity but good treatment sensitivity. The present study presents psychometric findings for a multi-step/multi-task BAT that assessed percentage of steps completed, subjective anxiety, global avoidance, and rituals. This measure was used with 50 clients diagnosed with OCD whose symptoms varied widely. The BAT demonstrated good convergent and divergent validity, as well as treatment sensitivity according to effect size calculations. A composite score combining steps, anxiety level, avoidance and rituals also performed well in psychometric tests. Strategies to reduce the complexity of scoring are presented, along with examples of several BAT tasks to enable researchers to employ this behavioral measure.
