Marsh, H. W., & Cheng, J. H. (2012). Physical self-concept. In G. Tenenbaum, R. C. (R. C. ) Eklund, & A. Kamata (Eds.), Measurement in Sport and Exercise Psychology (pp. 215-226).
The new emphasis in psychology is on positive psychology-on how healthy, normal, and exceptional individuals can get the most from life (e.g., Marsh & Craven, 2006; Seligman & Csikszentmilialyi, 2000; Vallerand et al., 2003). Consistent with this emphasis, a positive self-concept is valued as a desirable outcome in sport, exercise, and health psychology as well as in many other disciplines (e.g., developmental, mental health, social, personality, and educational psychology). Methodologists are concerned with particular measurement and methodological issues inherent in the study of self-concept. Researchers with a major focus on other constructs also are often interested in how constructs in their research are related to self-concept. Professionals, practitioners, and policy makers in many areas of social services and welfare seek to improve the self-perspectives of their clients. Hence, self-concept is valued widely as a desirable outcome.
