Objective: A recent meta-review of attentional bias research in eating disorders suggests that meta-analyses and systematic reviews include many low-quality and underpowered studies (Stott et al., 2021). As such, we examined whether published research examining the link between attentional bias, using the emotional Stroop task, and eating disorders among women with eating disorders has evidential value (ruling out selective reporting of a statistically significant effect) using a p-curve analysis. A p-curve analysis plots significant p-values onto a curve from .01to .05 to examine its distribution. We hypothesized that the p-curve would be flat, indicating no true effect. Method: The hypothesis, database search strategy, and data analytic approach were pre-registered. The inclusion criteria were reports that compared control and eating disorder groups, reported inferential statistics, and that used body shape/weight or general threat target words. Results: Fifty published reports were included in the p-curve analyses. Unexpectedly, the half and full p-curves were significantly right-skewed, indicating evidential value. However, the results were not robust to the exclusion of the seven lowest p-values and on average, reports were underpowered. There were also 18 reports with null results (they had a p-value greater than .05), which precluded their inclusion in the p-curve analyses. Discussion: The findings suggest that most of the evidence from research examining attentional biases using the emotional Stroop task among women with an eating disorder or with elevated eating disorder symptoms is underpowered and so should be interpreted with considerable caution.

In the cognitive-behavioural model, dietary restraint follows from appearance overvaluation (i.e., the core psychopathology of disordered eating). However, little research has examined the association between appearance overvaluation and dietary restraint when accounting for shared variance with other factors. Moreover, results generally hinge on researchers' decision-making, including addressing outliers and covariates. Herein, specification curve analysis was used to examine the association between appearance overvaluation and dietary restraint under 80 unique regression models based on different combinations of substantive factors and methodological decisions. Results indicated a positive association between appearance overvaluation and dietary restraint among university women (N=569; mean β=0.26), however, the association was not statistically significant when all factors were included in the model, and removal of outliers made results unstable. Hence, it is possible that sociocultural and cognitive-behavioural factors may be mediating or confounding the association. Findings also highlight the importance of limiting researcher degrees of freedom during data analysis.iii In loving memory of Meghan Reid iv AcknowledgementsThank you to my supervisor, Dr. Nassim Tabri, whose expertise and enthusiasm were invaluable in guiding my research questions and writing process.
