A variety of variables have been found to augment perceived social validity of behavioral interventions. In the present study, potential effects of behavioral function were evaluated. Sixty students inexperienced in work with people with mental retardation, and 60 experienced staff watched one of two carefully matched acted videos depicting self-injury maintained by attention or escape from task demands. Participants were also told whether the self-injury depicted typically led to mild or severe consequences for the person filmed. Participants rated six interventions in terms of their acceptability and effectiveness for the behavior depicted. A hierarchy of acceptability was replicated: reinforcement-based procedures were rated as more acceptable and effective. There were also effects of behavior severity and rater experience. However, few effects of behavioral function were found. Potential implications of staff undifferentiated attitudes towards functional treatments are discussed.
已发现多种变量可增强行为干预的感知社会效度。在本研究中，对行为功能的潜在影响进行了评估。60名没有与智力障碍者共事经验的学生和60名有经验的工作人员观看了两个精心匹配的模拟视频之一，视频描绘了因寻求关注或逃避任务要求而维持的自我伤害行为。参与者还被告知所描绘的自我伤害行为通常会给被拍摄者带来轻微还是严重的后果。参与者根据所描绘行为的可接受性和有效性对六种干预措施进行了评分。可接受性等级得到了重复：基于强化的程序被评为更可接受和有效。行为严重程度和评分者经验也有影响。然而，几乎没有发现行为功能的影响。讨论了工作人员对功能性治疗的无差别态度的潜在影响。
