BACKGROUND
Drop-out is a major problem in weight loss studies. Although previous attrition research has examined some predictors of drop-out, theoretically grounded research on psychological predictors of drop-out from weight interventions has been lacking.
PURPOSE
To examine psychological predictors of drop-out from a weight reduction study in diabetes type 2 patients.
METHOD
A clinical trial was conducted with 101 overweight/obese (body mass index >27) diabetes type 2 patients. Patients were randomly assigned to a self-regulation intervention, an active control group, and a passive control group. Psychological, somatic, socio-demographic, and lifestyle variables were examined as predictors of drop-out from baseline to 6 months follow-up.
RESULTS
Multiple logistic regression analysis indicated that low autonomous regulation or low 'goal ownership' was the best predictor of drop-out.
CONCLUSION
It is suggested that the assessment of 'goal ownership' prior to a weight reduction intervention could identify patients who are sufficiently motivated to participate. Patients who score low on 'goal ownership' may be offered pretreatment interventions to increase their motivation.
背景
脱落是减肥研究中的一个主要问题。尽管先前的流失研究已经检验了一些脱落的预测因素，但缺乏基于理论的体重干预脱落的心理预测因素的研究。
目的
检验 2 型糖尿病患者体重减轻研究中脱落的心理预测因素。
方法
对 101 名超重/肥胖（体重指数>27）的 2 型糖尿病患者进行了一项临床试验。患者被随机分配到自我调节干预组、主动对照组和被动对照组。将心理、躯体、社会人口统计学和生活方式变量作为从基线到 6 个月随访的脱落预测因素进行了检验。
结果
多元逻辑回归分析表明，自主调节水平低或“目标拥有”水平低是脱落的最佳预测因素。
结论
建议在进行体重减轻干预之前评估“目标拥有”，以确定具有足够参与动机的患者。“目标拥有”得分低的患者可能会接受治疗前干预以提高他们的动机。
