본 연구에서는 다른 사람의 건강과 관련된 행동이 개인의 건강행동에 영향을 미치는 과정과 이 때 사회비교동기가 조절효과를 지니는지 알아보고자 하였다. 이를 위해 건강한 섭식행동을 표적행동으로 삼아서, 타인의 건강행동빈도에 대한 지각과 사회비교동기가 이 표적행동을 예측하는지 알아보았다. 먼저 1차 시점에서 타인의 건강행동빈도를 주위 친구들의 행동과 자신 또래의 한국인들의 행동의 두 수준에서 측정하였고, 사회비교동기로써 자기향상동기를 측정하였다. 이에 더해서 섭식행동 빈도의 수준을 측정하였고, 각 행동에 대한 태도, 주관규범, 지각된 행동통제력 및 행동의도를 측정하였다. 2차 시점에서는 행동빈도지각과 각 표적행동 빈도의 수준을 측정하였다. 결과를 보면, 자기향상동기가 높은 사람들은 자신 또래의 한국인들 가운데 건강한 섭식행동을 하는 이들이 많다고 지각할수록 건강하게 섭식하는 행동빈도가 높아졌다. 그리고 이 효과는 계획된 행동이론에서 제안한 행동의 예측요소들의 설명력에 더해서 추가적으로 설명에 기여하였다. 끝으로 본 연구에서 얻은 결과들과 시사점을 선행연구들과 관련지어서 논의하였다.
This study was to investigate the effects of prevalence and social comparison while others' health behaviors influence one's health behavior. For this purpose, we chose healthy dieting as the target behavior and asked the participants to estimate prevalence of healthy dieting among their friends and among Koreans of their ages. We also measured self-improvement motive as a social comparison tendency, healthy dieting of the participants, in addition to attitude, subjective norm and perceived behavioral control. Three months later, the participants reported the prevalence and frequencies of their healthy diet behaviors for the second time. The results showed that the more a participant estimated the prevalence of healthy diet behavior among Koreans of their ages, the higher his/her healthy dieting, which pattern was significant among the people with high level of self-improve motive. Also, the interaction effect increased variance of explanation in addition to the effects of the factors which were suggested as the predictors of behavior by Theory of Planned Behavior. Finally, the limitations of this study and the implications for future studies were discussed.
