| Abstract: | The present study tested a motivational model where the beneficial impact that processes of cognitive adaptation have on mental health takes place through self‐determined motivation. The model proposes that the components of cognitive adaptation theory (positive self‐perceptions, perceptions of control, and optimism) foster a self‐determined motivation. In turn, self‐determined motivation predicts positive indices of mental health. In addition, the model posits that the beneficial role of cognitive adaptation on mental health is mediated by motivational processes. The model was tested using a 1‐year prospective design with a random sample from the general population. Results from structural equation modelling analysis provided empirical support for the proposed model. Results are discussed with regards to Taylor's ( 1983 ) cognitive adaptation theory, self‐determination theory (Deci & Ryan, 1991 ), and the Hierarchical Model of Intrinsic and Extrinsic Motivation (Vallerand, 1997 ).
