Relations between problem orientation and optimism, pessimism, and trait affectivity: A construct validation study

This study investigated the construct validity of the Positive and Negative Problem Orientation scales of the Social Problem-Solving Inventory—Revised (SPSI-R) by examining the relations between these scales and measures of optimism, pessimism, and trait affectivity. Consistent with expectations based on social problem-solving theory, positive problem orientation was found to have a relatively large amount of variance in common with optimism and positive affectivity, and negative problem orientation was found to share a large amount of variance with pessimism and negative affectivity, but not enough to be considered redundant in either case. Positive problem orientation was found to add significant incremental validity to the prediction of adaptive problem-engagement coping even after partialing out the variance associated with optimism and positive affectivity. In addition, negative problem orientation was found to add unique variance to the prediction of psychological distress even after controlling for pessimism and negative affectivity.
