对364名(130名男性)志愿者(60-87岁)进行了实验性骨关节炎干预中的磨耗研究。受试者被随机分配到对照组、社会支持组、教育组或联合治疗组。一系列判别函数分析表明，最终干预组比原始样本更加均匀。对人员流失最有力的预测因素是抑郁得分高或低。社会支持变量是社会支持组出席率较低的预测因子，这表明在评估这种治疗时可能存在自然减员倾向。结果表明，心理社会变量可能是老年健康干预研究中最好的磨耗预测因子，与磨耗相关的变量可能与干预的内容有关。
Attrition in an experimental osteoarthritis intervention was studied among 364 (130 male) volunteers (ages 60-87). Subjects were randomly assigned to control, social support, education, or combined treatment groups. A series of discriminant function analyses showed that the final intervention groups were more homogeneous than the original samples. The most robust predictor of attrition was having either high or very low depression scores. Social support variables were predictors of poor attendance in the social support group, indicating possible attrition bias in evaluating this treatment. The results indicate that psychosocial variables may be the best predictors of attrition in health intervention research among older subjects, and that variables related to attrition can be related to the content of the intervention.
