Self-efficacy is an important predictor of treatment outcomes for a variety of addictive behaviors. However, little research is available regarding its predictive value in obesity treatment. We assessed the predictive validity of the 20-item version of the Weight Efficacy Lifestyle Questionnaire (WEL) in a consecutive sample of 109 obese adults seeking outpatient treatment at a university-based weight-management center. Although the WEL demonstrated a stable factor structure and sound psychometric properties, it failed to correlate with either program attendance or weight loss. We concluded that self-efficacy judgments (as measured by the WEL) are not predictive of short-term obesity treatment outcomes.
自我效能感是多种成瘾行为治疗结果的重要预测指标。然而，关于其在肥胖治疗中的预测价值的研究却很少。我们在一家大学体重管理中心对109名寻求门诊治疗的肥胖成年人连续样本中评估了20项版体重效能生活方式问卷（WEL）的预测效度。尽管WEL显示出稳定的因素结构和良好的心理测量特性，但它与治疗参与率或体重减轻均无相关性。我们得出结论，自我效能感判断（通过WEL测量）并不能预测短期肥胖治疗结果。
