One of the most widely cited personality scales in social and consumer psychology. High self-monitors show greater brand-image sensitivity, adapt purchasing to social situations rather than personal attitudes, and are more responsive to image-based advertising appeals. Low self-monitors show greater consistency between attitudes and behaviour, and are more responsive to quality/performance advertising. Mean scores: actors M=18.41, students approximately midpoint, psychiatric patients M=10.19. KR-20 reliability 0.63–0.70. An 18-item reduced version (Snyder & Gangestad 1986) with alpha >0.70 is also available.
