The Roles of Constructive Thinking and Optimism in Psychological and Behavioral Adjustment During Pregnancy

This study examined the impact of constructive thinking on the anxiety, positive states of mind, and substance use of 221 women during pregnancy and the influence of optimism and perceived stress on these relationships. Participants were interviewed both early and late in pregnancy. Constructive thinking predicted both psychological and behavioral adjustment later in pregnancy, independent of age and social desirability. Subsequent path analyses indicated that constructive thinking mediated the impact of optimism on anxiety, positive states of mind, and substance use during pregnancy. In turn, the effect of constructive thinking on women's adjustment during pregnancy was itself mediated by their perceived stress. Implications for constructive thinking and optimism as independent constructs relevant to adjustment and their potential importance for future research and clinical applications are discussed.
