1. Religiousness and Depression: Evidence for a Main Effect and the Moderating Influence of Stressful Life Events T. Smith, M. McCullough, and J. Poll Presented by Lynn Carlson Radford University

2. Purpose To analyze the association between religiousness and depression and what factors influence the relationship. To analyze the association between religiousness and depression and what factors influence the relationship.

3. Goals of Meta-Analysis 1. Estimate the average magnitude of association between measures of religiousness and depressive symptoms. 2. Assess whether association is due to a main effect model, stress-buffering model, or both. 3. Identify characteristics of study samples and methods that might explain variation in religious-depression association.

4. Issues to consider Moderating and Mediating Variables Moderating and Mediating Variables Reciprocal relationships Reciprocal relationships Genetic influences Genetic influences Developmental influences Developmental influences Depressive influences on religion Depressive influences on religion Religious influences in depression Religious influences in depression

12. Conclusion There is evidence that religiousness is a robust correlate of depressive symptoms, even thought it is a small one There is evidence that religiousness is a robust correlate of depressive symptoms, even thought it is a small one Can attribute association to both the main effect model and the stress buffering model Can attribute association to both the main effect model and the stress buffering model No evidence that age, gender, or ethnicity moderated the association No evidence that age, gender, or ethnicity moderated the association
