Analyses of covariance performed for all snack foods separately. Dependent variable was intake and independent variable was the interaction between negative affect and perceived life stress score (see Table 1 for descriptive stats for negative affect and perceived life stress score). P-values for slopes were held to Bonferroni correction (k = 6, P ≤ 0.008). N = 29. MS, mean square. Est, estimate (for intercept or slope of negative affect x perceived life stress interaction). SEM, standard error of the estimate.
