Does personality moderate the relationship between stress and health behavior? Expanding the nomological network of the five-factor model

The present study tested the hypothesis that personality would moderate the stress to health behavior relationship. Using a community sample, 706 adults (Mean age = 37 years) were administered a set of five-factor model adjective rating scales, measures of stress and distress (i.e., negative life stress, physical symptom intensity, negative mood), health behaviors, as well as a demographic questionnaire. Using hierarchical multiple regression, Openness to Experience, Extraversion, and Neuroticism were found to moderate the stress to health behavior relationship. Supplementary analyses were conducted to determine if the five-factors would also moderate a life event to distress relationship. While several main effects were found, Conscientiousness was found to buffer the stress to distress connection. The factors that may influence both moderator models, suggestions for integration, and future research are discussed.
