“…Disturbances in body image are increasingly being recognised as a public health concern, being associated with poor quality of life (Griffiths et al, 2016) as well as increased risk for a range of difficulties, most notably eating disorders, but also depressive symptoms, overweight, and unhealthy weight control behaviours, such as cigarette smoking (Field et al, 2005; Loth, Watts, Van Den Berg, & Neumark-Sztainer, 2015; Patalay, Sharpe, & Wolpert, 2015; Rohde, Stice, & Marti, 2015; Sonneville et al, 2012; Sonneville et al, 2015). Despite the centrality of body image disturbances in models of risk and maintenance (e.g., Fairburn, Cooper, & Shafran, 2003; Stice, Gau, Rohde, & Shaw, 2017), and in diagnostic criteria for eating disorders (American Psychiatric Association, 2013), this construct remains relatively loosely conceptualised, with terms often used interchangeably, or captured under umbrella concepts, such as ‘weight and shape concerns’ (e.g., La Mela et al, 2015; Murphy, Dooley, Menton, & Dolphin, 2016).…”
