Abstract
According to social constructionist theory, an individual's understanding of the world serves to maintain social order and well-being. In this study, this assertion was tested by investigating a mediating process through the contribution of world understanding to problem-solving confidence. Causal modeling with data from 138 married couples in Hong Kong supported this mediating process: World understanding was positively related to problem-solving confidence, which in turn was positively related to well-being, defined by life satisfaction and depression. In addition, social support and exposure to information were possible determinants of one's world understanding. Social support also contributed to problem-solving confidence and well-being. The causal model was applicable to both husbands and wives.
