Personal incentives as determinants of adolescent health behavior: the meaning of behavior

It has been suggested that prevailing theories do not fully incorporate the less rational, more emotional elements of adolescent health and risk behavior. To address this limitation, the perceived incentives construct from Tappe's Model of Personal Investment is split into intrinsic and extrinsic incentives, with the intrinsic incentives representing personal meanings of adolescent health and risk behaviors. Intrinsic incentives were operationalized using transcripts from focus group interviews for three behavioral domains: sleeping habits, eating habits at lunch and eating habits after school. The ensuing questionnaire was completed by 416 Dutch secondary school students with a mean age of 14 years. Intrinsic incentives, or the personal meaning with which behavior is imbued, predicted health and risk behaviors well in all three behavioral domains. The implications of these results for further research and for the development of health education programs are discussed.
