Goal-directed behavior in individuals with mild Parkinson's disease: Role of self-efficacy and self-regulation.

ABSTRACT: Deficits in goal-directed behavior are common in individuals with Parkinson's disease (PD) and have been ascribed to apathy. In addition to apathy, individuals' beliefs in their competence (self-efficacy) and capacity to regulate emotions, thoughts, and actions (self-regulation) are critical skills for goal-directed behavior.

We correlated the scores on these scales with measures of cognition, anxiety, depression, apathy, fatigue, qual
