Negative problem orientation (Part II): construct validity and specificity to worry.

Negative problem orientation, a dysfunctional set of attitudes related to problem-solving ability, has been implicated as a process variable in several psychological disorders, notably depression and generalized anxiety disorder (GAD). The goal of the present study was two-fold: (1) to further examine the construct validity of a new measure of negative problem orientation, the negative problem orientation questionnaire (NPOQ), through its relationship to conceptually similar variables, and (2) to investigate the specificity of negative problem orientation to worry, the cardinal feature of GAD, compared to depression. The sample consisted of 148 university students who completed six questionnaires, the NPOQ and measures of worry, depression, pessimism, self-mastery, and neuroticism. Multiple hierarchical regressions revealed that when entered in the last step following demographic information and personality variables (pessimism, self-mastery, and neuroticism), the NPOQ accounted for 5.6% of the variance in worry scores compared to 1.6% of the variance in depression scores. It was concluded that the NPOQ shows evidence of construct validity, and that the process variable of negative problem orientation appears to have greater specificity to worry than depression. Implications for the understanding of worry and GAD are discussed.
