Pica is a potentially deadly form of self-injurious behavior most frequently exhibited by individuals with developmental and intellectual disabilities. Research indicates that pica can be decreased with behavioral interventions; however, the existing literature reflects treatment effects for small samples (n = 1-4) and the overall success of such treatments is not well-understood. This study quantified the overall effect size by examining treatment data from all patients seen for treatment of pica at an intensive day-treatment clinical setting (n = 11), irrespective of treatment success. Results demonstrate that behavioral interventions are highly effective treatments for pica, as determined by the large effect size for individual participants (i.e., NAP scores ≥ .70) and large overall treatment effect size (Cohen's d = 1.80).
异食癖是一种具有潜在致命性的自我伤害行为，最常出现在发育障碍和智力残疾个体中。研究表明，行为干预可以减少异食癖；然而，现有文献反映的是小样本（n = 1 - 4）的治疗效果，此类治疗的总体成功率尚不清楚。本研究通过检查在强化日间治疗临床环境中接受异食癖治疗的所有患者（n = 11）的治疗数据，对总体效应量进行了量化，无论治疗是否成功。结果表明，行为干预是治疗异食癖的高效疗法，这由个体参与者的大效应量（即NAP分数≥0.70）和总体大治疗效应量（科恩d值 = 1.80）所确定。
