Feasibility and acceptability of a theory-based online tool for reducing stress-induced eating.

Stress-induced eating is associated with various health risks like obesity and cardiovascular disease, exacerbated by the overconsumption of unhealthy foods. This study sought to investigate replacement coping strategies for stress-induced eating that participants can seek to implement using behaviour change techniques like implementation intentions. The study adopted a feasibility and acceptability design, with 258 participants (88.37% female) aged 17-75 years old who self-reported stress-induced eating. Participants were asked to identify cues for their stress-induced eating and evaluate the acceptability of eight potential replacement coping strategies. After selecting their preferred strategy, participants formed implementation intentions, linking the strategy with their previously identified cues. There were six themes of cues for stress-induced eating as identified by participants, including a range of external and internal stressors. Themes regarding the acceptability of the replacement coping strategies were organised based on constructs from integrated social cognition theories. Participant responses reflected cognitive and affective attitudes, and control and normative beliefs behind engagement in coping behaviour; further, automatic and volitional processes were described by participants as playing a role in whether a coping strategy was deemed as useful. Plans formulated by participants commonly detailed specific situations and strategies to utilise, though few described start times or durations of their plan. Action planning was found to significantly increase following formation of implementation intentions, and participants' descriptions supported the feasibility and acceptability of utilising implementation intentions to adopt alternative coping strategies to stress-induced eating. Future research should conduct a randomised controlled trial to assess the efficacy of the implementation intentions intervention in promoting uptake of replacement coping strategies to reduce stress-induced eating.
