Summary of Overall Effect Sizes for the Predictive Relationship between Specific and Categoric/Overgeneral Memories and Depressive Symptoms at Follow-up

	Correlational Data Set		Standardized Regression Coefficient Data Set
Variable	Specific	Categoric/Overgeneral	Specific	Categoric/Overgeneral
Number of studies	4	8	6	6
Weighted overall effect size(ES)^a	−.10⁺	.13^**	−.17^*	.11^*
95% CI for ES	−.22, .02	.04, .23	−.31, −.03	.02, .20
Homogeneity (Q)	4.38	6.34	11.54^*	3.58
I² index	31%	0%	57%	0%

Note. CI = confidence interval. Nonsignificance of the Q statistic indicates a failure to reject the hypothesis of homogeneity. The I² index represents the percentage of the total variability in effect size estimates that is due to true heterogeneity between studies. Effect sizes are based on a random effects model.

Effect sizes are weighted by the reciprocal of the variance.
