Suh, Choi, and Chung: Psychosocial Factors Related with the Intake of Vegetables and Fruits by Stage of Change of Elementary School Children in Chungnam Province

Abstract

This study aims at investigating the psychosocial factors that influence on the intake of fruits and vegetables according to stage of change in rural children. Total 256 elementary school children, located in Yeongi-Gun, Chungnam-Do were surveyed from May 14 2007 to May 30 2007. Stage of change on the intake of fruits and vegetables of the students was categorized into three stages: precontemplation (PC), contemplation & preparation (CO&PR) and action (AC). Psychosocial factors consist of decisional balance based on pros and cons, process of change of cognitive and behavioral processes, and self-efficacy. The recognition of cons out of decisional balance showed the highest score in the subjects at the stage of PC and lowest score in those action stage. While, no difference was shown in the score of recognition of pros among the stages. Both levels of cognitive and behavioral process of change showed no difference between two pre-action stages, PC and CO&PR. However, the subjects of action stages got higher scores in more number of the variables in both of cognitive and behavioral process of change compared to those of pre-action stages with more remarkable in results vegetables than in fruits. The results of self-efficacy on fruits and vegetables intake showed that the higher stages of change, the higher the self-efficacy score. From the result, it is suggested that the items and level of psychosocial factors are different according to the stage of change and between fruits and vegetables in rural children.
