Sex differential mediation effects of planning within the health behavior change process.

Objective: Previous research demonstrates that planning mediates the relationship between intention and health behavior change, but evidence is inconclusive, and possible sex differences within the intention-planning-behavior-chain are understudied so far. The current study, therefore, aims to disentangle this by addressing potential sex differences in the mediating role of planning in the health behavior change process.

Method: Three longitudinal studies were conducted in Germany between 2009 and 2011 (Study 1: 245 women, 216 men; Study 2: 156 women, 37 men; Study 3: 82 women, 84 men).

Social network, autonomy, and adherence correlates of future time perspective in patients with head and neck cancer.

Objective: Socioemotional selectivity theory proposes that, with more limited future time perspective (FTP), the meaning of individual life goals shifts from instrumental and long-term goals, such as autonomy, to emotionally meaningful and short-term life goals, especially concerning meaningful social relationships. Adverse side effects of cancer therapy may conflict with the realization of emotionally meaningful goals leading to nonadherence. In line with the theoretical assumptions, this study aimed to investigate (a) associations among disease symptoms, physical and cognitive limitations, and FTP and (b) among FTP, family network size, striving for autonomy, and treatment adherence.
