Loss of control as a transdiagnostic feature in obesity-related eating behaviours: A systematic review.

OBJECTIVE: Emerging evidence suggests that loss of control (LOC) may present as a common feature across disordered eating behaviours. However, there has been limited research on the transdiagnostic nature of LOC in this area. The primary aim of this study was to systematically review disordered eating behaviours and measures of LOC in clinical and non-clinical populations. METHOD: Electronic searches of the relevant databases were conducted. Selected articles were screened for eligibility and assessed for methodological quality. RESULTS: Thirty-four studies met inclusion criteria. Findings demonstrated that LOC was associated with disordered eating behaviours across bariatric populations, eating disorder populations, and community populations. Specifically, LOC was associated with binge eating (subjective and objective episodes), grazing, night eating, and emotional or stress eating. Findings also revealed that LOC was inconsistently operationalised across studies, with varied approaches to measuring the construct. CONCLUSION: Overall, the findings from this review provide support for LOC as a transdiagnostic feature of disordered eating behaviours. Future studies should utilise robust multi-method assessments to measure the severity of LOC, which may provide greater insight into how LOC manifests across different eating disorder presentations.

Stress, savouring, and coping: The role of savouring in psychological adjustment following a stressful life event.

There is increasing research on the role of savouring positive emotional experience in the context of stress. As such, we need a better understanding of how savouring and coping relate to each other and to psychological adjustment outcomes following a stressful life event. In particular, this study seeks to understand whether savouring is better conceptualized as a coping resource or a coping response. Three hundred people who experienced a highly stressful event in the past year completed measures of impact of event, savouring, coping, positive emotions, depression, anxiety, and life satisfaction. Results of bivariate correlations showed that savouring is positively correlated with positive coping (i.e., mastery and meaning-based coping) and socially-supported coping (i.e., using emotional and instrumental support) and negatively correlated with negative coping (i.e., self-judgement and avoidance coping). The results of path analyses support a model that positions savouring as a coping response that relates to other coping responses and indirectly relates to better psychological adjustment through positive emotions (when psychological adjustment is conceptualized as depression or life satisfaction but not anxiety). Findings provide preliminary support for conceptualizing savouring as a coping response; future research should consider measuring savouring as a coping response to further our understanding of savouring following a stressful life event.
