The most widely cited measure of goal commitment in organisational and consumer psychology, derived from Klein et al.'s meta-analytic review of 83 prior goal commitment operationalisations across 25,000 participants. Alpha consistently 0.76–0.87. Goal commitment is the volitional determination to pursue and attain a specific goal — conceptually distinct from goal importance (how much one values the goal outcome) and goal acceptance (agreement with the goal). The GCS captures both reluctance to abandon the goal and active determination to reach it. In Locke and Latham's goal-setting theory, commitment moderates the goal difficulty–performance relationship — challenging, specific goals produce better performance only among committed individuals. In consumer research, goal commitment predicts purchase follow-through, brand loyalty aligned with aspirational goals, adherence to diet and exercise intentions, and resistance to temptation when a committed goal competes with hedonic impulses. Goal commitment also moderates the effectiveness of self-referential advertising — committed consumers respond more strongly to messages reinforcing their existing goal. Widely used in sales force research, service employee motivation, consumer goal pursuit, and health behaviour change. Goal commitment is goal-specific — always assessed with reference to a particular named goal.

Items 1 and 2 are reverse-scored before averaging. The GCS is goal-specific — participants should respond with reference to a particular stated goal (e.g., 'Thinking about your goal to [X]...') rather than goals in general. Klein et al.'s meta-analysis clarified that goal commitment should not be confounded with goal difficulty: one can be highly committed to an easy goal or weakly committed to a difficult goal. Goal commitment predicts performance incrementally over goal difficulty and self-efficacy. In consumer research, goal commitment measured before a behavioural decision predicts actual purchase follow-through more strongly than intention alone. A 3-item short form (items 3, 6, 7) has been validated for longitudinal field research. The Hollenbeck, Williams & Klein (1989) scale is the earlier precursor; Klein et al. (1999) is the recommended standard.
