The Relationship Between Negative Problem Orientation and Worry: A Meta-Analytic Review.

Generalised Anxiety Disorder (GAD) can have a significant detrimental effect on the lives of sufferers.

Negative problem orientation (NPO) has been identified as an important psychological construct involved in worry (Gosselin, Ladouceur & Pelletier, 2005). The focus of this meta-analytic review was to further our understanding of the relationship between NPO and worry, and a related construct called intolerance of uncertainty (IU). The review identified 31 articles reporting correlations between measures of NPO and worry. These articles detailed a total of 33 independent effect sizes. Using a random-effects model and raw and attenuation-corrected values, NPO was found to be significantly correlated to worry (r = 0.57, CI = 0.55–0.60, k = 33, N = 5376). The type of NPO measure moderated the relationship between NPO and worry. In addition, NPO was found to be significantl...
