The Science of Body ImageWeight and body image -
All latent variables were specified as reflective. The standardized path coefficients between latent variables β and the variance explained in the endogenous variables R 2 were examined. Structural paths were retained if they were statistically significant.
Where there were significant intervening paths connecting distal variables, tests of mediation were conducted using the bootstrapping procedures incorporated in SmartPLS. When examining mediating effects, past work has shown the bootstrapping approach to be superior to the alternative methods of testing mediation, such as the Sobel test, with respect to power and Type I and II error rates [ 51 ].
Baron and Kenny's [ 52 ] formal steps for testing mediation were also followed. Full mediation is present when the indirect effect is significant, and there is a direct effect in the absence of the intervening variable C path that becomes non-significant in its presence C' path.
Partial mediation is present when the C' path is reduced but remains significant [ 53 ]. In addition, the ratio of the indirect effects to the direct effects was calculated to express the strength of the mediation effects [ 54 ]. As mentioned earlier, PLS does not make data distribution assumptions, thus parametric tests for the significance of the estimates are not available.
Instead, SmartPLS employs a bootstrapping procedure to assess the significance of the parameter estimates. In the present analyses bootstrap samples with replacement were requested.
SmartPLS does not provide significance tests for the R 2 values for dependent latent variables. Therefore, the effect sizes of the R 2 values Cohen's f 2 were calculated.
Effect sizes of. The central focus of this study was to test a three-level model by which a behavioral weight control intervention, encompassing a body image component, produced effects on eating self-regulation.
The main effects of the intervention on weight and key psychosocial variables are described elsewhere [ 55 ].
In brief, at the end of the intervention 12 months , average weight loss was higher in the intervention group Evaluative body image was enhanced, body image investment decreased, and eating self-regulation variables improved showing large effect sizes; significant between-group differences favoring the intervention were observed [ 55 ].
Therefore, the indicators with the lowest loadings were eliminated and the model re-estimated until acceptable AVEs were obtained. Figure 1 displays the lower-and higher-order LV's and the bootstrap estimates for the respective factor loadings.
Table 1 shows the CRs, AVEs, and correlations among the latent variables. CRs for all scales were greater than. Moreover, AVEs for each latent variable were greater than the squared bivariate correlations with all the other latent variables, with the exception of the associations between lower-order variables and their respective higher-order LV, as expected.
Taken together, these findings suggest that the measurement model had acceptable internal consistency, convergent validity, and discriminant validity. Partial least squares model. Figure 1 shows the PLS bootstrap estimates for the structural paths, and the variance accounted for in the dependent variables R 2.
Treatment positively predicted the change in body image investment and evaluative body dissatisfaction. Although both components improved significantly, treatment effects on the investment component were stronger effect size.
In turn, the positive changes in body image components resulted in an increase in eating self-regulation. Given the observed path coefficients, the effects of body image investment on eating self-regulation appear to be greater than the effects of evaluative body image paths: -.
In the face of these results and to further support the greater relative strength of investment over evaluative body image effects on eating behavior, the model was re-examined before and after the inclusion of investment body image change.
SmartPLS uses a blockwise estimation procedure, with only one part of the model being estimated at each time, which permitted the use of this additional analysis [ 48 ]. Results showed a substantial increase in variance explained in eating self-regulation from an R 2 of.
Table 2 shows the significant indirect effects between distal independent and dependent variables, and the resultant tests of mediation.
Treatment had a significant indirect effect on eating self-regulation, which was fully mediated by the change in body image investment effect ratio.
Results suggest that treatment effects on eating self-regulation occur especially through change in body image investment, given that the indirect effect via this dimension was greater than the one via evaluative body image path coefficients:.
To further explore the mediating role of body image change, secondary and more specific tests of mediation were conducted, considering each eating behavior as a separate outcome see Table 2.
Treatment had significant indirect effects on all measures of eating behavior flexible restraint, eating self-efficacy, disinhibition, and perceived hunger. The change in investment body image fully mediated the effects of treatment on each one of these variables; the effect ratios were all large.
In addition, the positive change in body dissatisfaction partially mediated the path between treatment and eating self-efficacy medium f 2.
Body image problems are highly prevalent in overweight and obese people seeking treatment [ 56 ] and are consistently associated with poorer weight outcomes and increased chances of relapse [e. In addition, poor body image has been consistently related to the adoption of maladaptive eating behaviors [e.
Thus, the advantage of tackling body image concerns in obesity treatment remains unquestioned. This study showed that body image improved during the intervention, confirming that behavioral weight loss programs, particularly those which include a body image module, can be an effective way of improving body image [ 25 , 57 ].
The present results extend previous findings by distinguishing evaluative and investment body image dimensions, showing that both can be enhanced, and that they differentially mediate the effects of a weight loss intervention on the successful regulation of eating behavior.
The conceptualized paths within the structural model were generally supported by the study's findings, accounting for a substantial portion of the variance in investment body image and eating-self-regulation. The study predictions were also generally supported.
Specifically, results showed that the intervention led to positive changes in body image which in turn resulted in the improvement of eating self-regulation. In addition, results revealed that relative to evaluative body image, the change in body image investment was more strongly related to the changes in eating behavior.
Finally, results showed that both body image dimensions mediated the significant effects of treatment on eating self-regulation.
Overall, body image change appears to be a valid mechanism through which the regulation of eating behavior can be improved in behavioral weight management interventions, at least in women. Results showed that this study's intervention led to improvements in both dimensions of body image, increasing body satisfaction, and decreasing dysfunctional investment in appearance.
These findings lend support to previous suggestions by Rosen and colleagues [ 57 , 58 ] recommending the inclusion of body image-related contents in weight management interventions. Although we must acknowledge that some improvement in body image might have been experienced due to weight reduction per se, the rationale for adding a body image component to the intervention is that it will enable participants "to exercise their new self-image more effectively and to unlearn body image habits that do not give way to weight loss" [[ 59 ]; pp.
In addition, prior research suggested that body image enhancement could also facilitate the use of psychological resources, resulting in better adherence to the weight management tasks [ 60 , 61 ]. Change in both body image dimensions resulted in positive changes in eating self-regulation.
Nevertheless, the present findings provide empirical support to the contention that reducing the levels of concern with body image i. Besides the larger effect of investment change on eating regulation compared to the effect of evaluative body image, we observed a substantial increase in the variance explained in eating self-regulation and a large f 2 for the change after the inclusion of investment body image in the model.
Previous research has shown that investment body image has more adverse consequences than evaluative body image to one's psychosocial functioning, and that dysfunctional investment in appearance is more associated with disturbed eating attitudes and behaviors than body dissatisfaction [ 21 , 23 ].
Explanation for these findings has been proposed to partially derive from a nuclear facet of body image investment, appearance-related self-schemas. These cognitive structures "reflect one's core, affect-laden assumptions or beliefs about the importance and influence of one's appearance in life, including the centrality of appearance to one's sense of self" [[ 62 ]; pp.
Appearance self-schemas derive from one's personal and social experiences and are activated by and used to process self-relevant events and cues [ 62 , 63 ]. According to Cash's cognitive-behavioral perspective [ 62 ], the resultant body image thoughts and emotions, in turn, prompt adjustive, self-regulatory actions i.
In addition, Schwartz and Brownell [ 61 ] argued that body image distress could form a barrier to emotion regulation that, for both biological and psychological reasons, could result in increased and unhealthy eating.
The present intervention significantly reduced participants' investment in appearance and its salience to their lives. Thus, it is possible that an increase in the acceptance of body image experiences and the deconstruction of held beliefs and interpretations about the importance of appearance to the self resulted in reduced appearance schemas' activation.
In turn, this might have led to improvements in the regulation of associated thoughts and emotions, leading to the adoption of healthier and more adaptive self-regulatory activities [ 21 ].
In the present study, the effects of treatment on eating self-regulation were mediated by changes in both body image dimensions. To further explore these findings, more specific analyses of mediation were conducted considering each lower-order component of eating self-regulation as a separate outcome.
Results suggested that the change in investment body image influenced all eating self-regulation variables, whereas the change in evaluative body image only mediated the improvement in eating self-efficacy. This finding could help explain why evaluative body image showed smaller effects in general; it mainly affected one of the four components of eating self-regulation used in this study.
This finding is not surprising. In the face of more realistic and achievable ideal body sizes, individuals should feel more confident in making a compensatory aesthetic difference by losing some weight, namely via changes in eating behavior.
In fact, prior research has suggested an association between seeing one's body as closer to the societal norm and self-efficacy for making healthy changes [c.
In addition, Valutis et al. On the other hand, body image investment is related to the salience of appearance to one's life and sense of self [ 21 ] and is associated with negative affect [c.
The use of mediation analysis is a methodological strength of the present study. Mediation analysis is particularly well-suited to identify the possible mechanisms through which interventions achieve their effects, allowing the development of more parsimonious and effective interventions by emphasizing more important components and eliminating others [ 67 ].
Improving overweight and obesity interventions remains a critical challenge [ 68 ] and the present study represents one more step in this direction. This study was the first to explore body image as a mediator of eating self-regulation during weight control and to analyze the distinct effects of evaluative and investment body image components.
The present findings are informative for professionals when designing future interventions, reinforcing the advantage of including a body image component within weight management treatments.
Our results further suggest that within this intervention module, the strategies used to target body image investment should be emphasized to more effectively improve the regulation of eating behavior, and in turn more successfully manage body weight.
This could be achieved by actively deconstructing and defying held beliefs and predefined concepts about the centrality of appearance to one's life and sense of self, mindfully accepting and neutralizing negative body image emotions, identifying problematic thoughts and self-defeating behavior patterns, and replacing them with healthier thoughts and behaviors [ 69 ].
Investigating specific mechanisms responsible for the successful regulation of eating behavior e. Future studies might find it important to continue to investigate this higher-order construct as a relevant outcome in weight loss interventions. This notwithstanding, the identification of other variables which may mediate the effects of treatment on eating self-regulation, for instance, related to physical activity [ 70 ], should be pursued.
Four limitations of the present study are noteworthy. First, although this was a longitudinal study and we did measure change in the variables of interest, changes in body image and eating measures occurred during the same period.
Thus, we cannot exclude the possibility of alternative causal relations between these variables. It is possible that the change in eating self-regulation led to positive changes in body image, or that these variables reciprocally influence each other.
However, based on the existing literature suggesting that poor body image is a precursor of dysfunctional eating behaviors [ 15 , 16 , 19 ], we hypothesized that it was the change in body image that resulted in positive changes in eating self-regulation.
Second, the psychometric instruments used herein to measure investment body image were only able to capture some facets of this construct - over-preoccupation with body image and appearance and its behavioral consequences - thus failing to capture another core facet of body image investment, the appearance-related self-schemas.
Future studies should include more comprehensive measures that are able to capture these additional facets of body image investment. Third, the format of the instrument used to assess evaluative body image has some inherent limitations.
The Figure Rating Scale is a unidimensional and undifferentiated measure of body dissatisfaction that differs considerably from all other body image measures in format.
By contrast, body image investment was assessed with more sophisticated and multidimensional instruments. This could account for the lesser role of the evaluative component in our model. Future studies should use multi-item questionnaire-type measures to assess evaluative body image.
Finally, the generalizability of the findings in this study may be limited to overweight and obese women seeking treatment, a population that is particularly prone to body image disturbances, weight preoccupation, and dysfunctional eating patterns [ 7 , 56 , 71 ].
The effect of body image enhancement on eating self-regulation in other populations remains unknown. Results showed that both evaluative and investment body image are relevant for improving eating self-regulation during obesity treatment in women, and suggested that the investment component might be more critical.

Effects of negative body image A negative body image or experiencing body dissatisfaction can lead to: dieting over-exercising the development of eating disorders such as anorexia nervosa , bulimia nervosa and binge eating disorder the development of other mental health issues such as low self-esteem, depression or anxiety.
Why diets don't work Dieting is a significant risk factor for developing an eating disorder. The diet cycle The typical diet cycle involves: Starting a diet — often quite rigid and limits the amount, type of frequency of food and eating.
Short-term weight loss — noticing changes in body shape or weight and feeling successful and in control. Deprivation — the body responds physically and mentally. Your metabolism slows, hunger increases, and people experience a preoccupation with food and eating.
Diet rules are broken — inevitably, due to deprivation, the diet rules are broken. People experience feelings of guilt, failure and disappointment. Weight loss is regained — this can be associated with eating foods not part of the diet, eating when not hungry, and sometimes overeating or binge eating.
