Little is known about the psychological mechanisms that underlie financial planning for retirement. Most studies of financial planning and investing have used demographic indicators (e.g., age, gender, income) to predict individual differences in saving. In the present study, a model of planning is tested in which psychological indicators (future time perspective, retirement goal clarity, and self-rated financial knowledge) are posited to mediate the relationship between demographic indicators and saving behaviors. Path-analytic techniques were used to test the model, based on data from 265 middle-aged working adults. Analyses revealed substantial support for the role of psychological factors in the retirement planning process. Findings have theoretical implications for the development of psychologically based models of planning, as well as applied implications for those who seek to understand the psychomotivational forces that underlie tendencies to plan and save.
