In Table 1, the authors state that skewness and kurtosis values meet normality assumptions (between +1.5 and –1.5). However, they do not provide the actual table for examination. Given the large sample size (n=528), even minor deviations could affect parametric tests. Can the authors provide the full Table 1 with all skewness and kurtosis values, and explain why they chose ±1.5 as the cutoff instead of more conservative thresholds (e.g., ±1.0)?
In Table 3 (Total, direct, and indirect effects), the indirect effects for cognitive reappraisal and expressive suppression appear very similar in magnitude for both depression and stress pathways. For example, cognitive reappraisal indirect effect on depression is 0.08 and on stress is also 0.08. This is unusual in psychological data. Could the authors provide the covariance matrix or confirm if multicollinearity was tested among mediators? Also, why was bootstrapping performed with only 5,000 resamples instead of the more common 10,000?
The conceptual model in Figure 1 is mentioned but not included in the provided text. The model presumably positions psychological flexibility and emotion regulation as parallel mediators. However, in the discussion, the authors treat them as independent mechanisms without addressing potential overlap or interaction. Can the authors clarify whether they tested a serial mediation model or examined mediator-mediator interactions, given that psychological flexibility and cognitive reappraisal are theoretically related?
