Although drop out rates in weight management interventions are high, little is known about characteristics of people dropping out at different time points during such interventions. This study aims to examine characteristics of early and late drop outs during a self-management intervention aimed at weight control, hypothesizing that changes in psychological characteristics during active intervention would differentiate drop outs from completers. Participants' (N = 167) socio-demographics and personality traits were measured via self-report at baseline, as well as their behavioral and psychological outcomes before and during the intervention. No baseline differences were found between early drop outs and initial completers. As expected, late drop outs were characterized by a different change pattern in self-efficacy during the initial phase compared to completers. Few differences in other characteristics were found. Changes in self-efficacy during active intervention are relevant for understanding drop out in weight management interventions.
尽管体重管理干预措施的辍学率很高，但对于在这些干预措施的不同时间点辍学的人的特征知之甚少。本研究旨在检查在一项旨在控制体重的自我管理干预措施中，早期和晚期辍学者的特征，假设在积极干预期间心理特征的变化将使辍学者与完成者区分开来。参与者（N=167）的社会人口统计学特征和人格特质通过自我报告在基线时进行了测量，以及在干预前和干预期间的行为和心理结果。在早期辍学者和初始完成者之间没有发现基线差异。正如预期的那样，与完成者相比，晚期辍学者在初始阶段的自我效能方面表现出不同的变化模式。在其他特征方面发现的差异很少。在积极干预期间自我效能的变化对于理解体重管理干预中的辍学现象很重要。
