Individuals with overweight/obesity and loss-of-control eating (LOC) may experience poorer outcomes from behavioural weight loss due to reactivity to internal (e.g., affective and physical) states that impact treatment adherence (e.g., dietary lapses). This study examined (a) whether the presence of LOC increased risk for dietary lapses and (b) the moderating role of LOC on the relation between internal states and dietary lapses.
Individuals (n = 189) with overweight and obesity completed ecological momentary assessment early in behavioural weight loss.
LOC was positively associated with dietary lapse. LOC did not moderate the relation between momentary changes in internal states and dietary lapses. However, the effect of average levels of internal states on lapses was attenuated for those with LOC.
Results suggest that those with LOC are at higher risk of dietary lapse, whereas elevated average levels of internal states may contribute to early inadherence for those without LOC.
超重/肥胖和失控进食(LOC)的个体可能由于对影响治疗依从性(例如饮食失误)的内部(例如情感和身体)状态的反应,导致行为减肥的效果较差。本研究考察了(a)LOC 是否增加了饮食失误的风险,以及(b)LOC 对内部状态与饮食失误之间关系的调节作用。
超重和肥胖的个体(n=189)在行为减肥的早期完成了生态瞬时评估。
LOC 与饮食失误呈正相关。LOC 并没有调节内部状态的瞬间变化与饮食失误之间的关系。然而,对于有 LOC 的人来说,内部状态的平均水平对失误的影响减弱了。
结果表明,有 LOC 的人更容易出现饮食失误,而对于没有 LOC 的人来说,较高的内部状态平均水平可能导致早期不依从。
