Body checking and body avoidance, considered to be behavioural manifestations of core attitudinal disturbances of body image, are theorized to be important contributors to the development and maintenance of eating disorder symptoms. Currently, however, it is unclear whether body checking and body avoidance accounts for variance in disordered eating behaviours beyond core attitudinal components of body image (i.e., over-evaluation, preoccupation, dissatisfaction). This was the objective of the present study. Cross-sectional data were analysed from 320 females recruited through undergraduate psychology programs and throughout the community. Bivariate correlations demonstrated that body checking and avoidance were significantly and positively correlated with each attitudinal component and with each measure of disordered eating (overeating, objective binge eating, and disinhibition). However, body checking and avoidance did not contribute variance (all R 2 changes  ≤ 0.01) to each disordered eating behaviour beyond the variance accounted for by attitudinal components. Future research should aim to identify what specific and unique function these body image behaviours serve. Overall, eating disorder prevention and early intervention programs may benefit from ensuring that all facets of body image concerns are targeted and addressed., (Copyright © 2018 Elsevier Ltd.

Previous studies have separately examined conformity to masculine norms and internalization of body ideals in the media in relation to the drive for muscularity (DM). This study was designed to examine these factors together in relation to DM, and further examine how they may differ in relation to drive for thinness (DT) and drive for leanness (DL). Participants were 284 Australian males between ages 18 and 42. They completed validated measures that assessed DM, DT, DL, male gender role norms, and internalization of body ideals. The findings showed that internalization of body ideals mediated the relationship between masculine role norms and body image in the case of both DM and DL. However, masculine norms and internalization were independent predictors of DT. Our findings contribute to further understanding of the roles that the media and masculine norms have in shaping men's drive for muscularity, leanness, and thinness. Longitudinal research is needed to confirm the nature and direction of these relationships., (Copyright © 2015 Elsevier Ltd. All rights reserved.)

The dual pathway model proposes that trait body dissatisfaction leads to bulimic symptoms via two distinct pathways: dieting and trait negative affect. As many of these modelled variables have state-based equivalents, the present study evaluated the generalisability of this model to predict associations between state body dissatisfaction and instances of disordered eating. 124 women aged 18 to 40 years completed an online survey (accessed via a mobile phone device with web access) over a 7-day period. The mobile phone device prompted participants at random intervals seven times daily to self-report their state body dissatisfaction, current mood experiences, dieting attempts, and disordered eating practices. Multi-level mediation modelling revealed that both negative mood states and dieting significantly mediated the state body dissatisfaction-disordered eating relationships, although the strength of these associations depended on the aspect of disordered eating measured and individual differences in trait body dissatisfaction, internalization of appearance standards, tendency towards dieting, and BMI. Collectively, these results not only support adapting the dual pathway model to the state-level, but also suggest that several of the model implied pathways may be more relevant for individuals with more pathological eating- and body-related concerns and behaviours., (Crown Copyright © 2014.
