Abstract: | This experiment examined the effects of pet ownership and potential mediating (e.g., social support) and moderating variables (e.g., gender, personality, pet attachment) on completion of a 12‐week cardiac rehabilitation program. This experiment assessed pet ownership, personality, and psychosocial variables at the beginning of the program and followed participants through to completion. Results showed that pet owners (96.5%) were significantly more likely to complete cardiac rehabilitation compared with non‐owners (79.2%). Covariance analyses ruled out several alternative explanations for the results, including social support, personality variables, personal efficacy, and pet attachment. Results suggest that having a pet may facilitate rehabilitation and that further research is needed to understand how having a pet or being a pet owner improves health outcomes. |
