This paper used brief psychological intervention to develop goal-setting and planning (GAP) skills in order to see if it would increase psychological well-being in a non-clinical sample. The intervention was tested in two separate studies: one involving group sessions and the other involving individual completion of the program. Both groups showed significant improvements in subjective well-being compared to the control groups. The findings suggest a causal link between goal-setting and planning and well-being and that these skills can be learned and applied to enhance overall well-being.
