Abstract
Picky eating can persist into adolescence and adulthood for some individuals and can be associated with undesirable psychosocial factors. Investigating associations with these factors may inform the development of effective prevention and intervention strategies and further research. Part One is a systematic review of the psychosocial correlates of picky eating beyond childhood. A range of psychosocial correlates were identified including eating disorder behaviours, mental health factors and identity-related difficulties. Picky eating behaviours may be associated with undesirable psychosocial outcomes, particularly mental health correlates. The results were more varied for eating disorder behaviours and identity-related difficulties. The review highlights the need for further research with methodological improvements to draw more robust conclusions.// Part Two presents empirical research into the psychosocial outcomes of picky eating in adolescence. To date, most of the evidence on correlates of picky eating focuses on either children or adult populations. There is some evidence that adolescents with PE habits experience social challenges and criticism from peers. Contrary to expectation, persistent picky eating was not associated with lower school engagement and enjoyment, friendship quality and higher bullying experiences. Other factors such as child sex, health conditions, household income and an autism diagnosis were found to have a greater influence on these associations. Efforts should be made to increase the generalisability of results and capture the difference in influence between transient PE, persistent PE, and ARFID on psychosocial outcomes.// Part Three presents a critical appraisal of the systematic review and empirical paper. Reflections on the research process for each part were considered including reflections on the choice of topic, the challenges present in the literature, methodological issues and potential clinical implications.
