The potential mediating roles of danger expectancies, responsibility, perfectionism, anticipated anxiety and self-efficacy on obsessive-compulsive handwashing were examined. Ratings were obtained from 27 obsessive-compulsive patients before and during a behavioural avoidance test involving a compound stimulus of potting soil, animal hair, food scraps and raw meat. Correlation and partial correlation analyses were conducted to examine the relationships between the cognitive predictor variables and anxiety, urge to wash, time in task and duration of post-test washing. Large and significant relationships between danger expectancies and the dependent measures were obtained, even when alternative mediators were held constant. No other variable remained significantly related to any of the dependent measures when severity of disease ratings were held constant. Results suggest that of the cognitive variables examined, danger expectancies are the most likely mediator of washing-related behaviour in obsessive-compulsive disorder.
研究了危险预期、责任感、完美主义、预期焦虑和自我效能感在强迫性洗手行为中的潜在中介作用。对27名强迫症患者在一项行为回避测试前和测试期间进行评分，该测试涉及盆栽土、动物毛发、食物残渣和生肉的复合刺激。进行了相关性和偏相关性分析，以检验认知预测变量与焦虑、洗手冲动、任务时间和测试后洗手持续时间之间的关系。即使其他中介变量保持不变，危险预期与相关测量指标之间也存在显著的强关联。当疾病严重程度评分保持不变时，没有其他变量与任何相关测量指标仍存在显著关联。结果表明，在所研究的认知变量中，危险预期最有可能是强迫症中与洗手相关行为的中介因素。
