杭州市大学生体重控制行为与心理控制源的典则相关分析

Canonical correlation analysis of weight-control behavior and weight locus of control among university students

目的探讨大学生体重控制行为与体重心理控制源的关系,为帮助大学生建立正确的体重控制观念提供参考。方法利用体重控制行为问卷和体重心理控制源量表,对分层整群抽取的杭州市1 504名大学生进行现场调查,并利用典则相关分析研究体重控制行为与体重心理控制源之间的关系。结果男生在体重控制行为的饮食行为、运动行为、寻求外部支持行为3个维度得分均显著高于女生(t值分别为8.90,13.98,2.43,P值均<0.05)。第1对典则变量主要反映大学生外在心理控制源与寻求外部支持行为之间的关系,第2对典则变量主要反映大学生偶然心理控制源与饮食行为之间的关系,相关系数分别为0.326,0.126(P值均<0.01),二者的累积贡献率达98.4%。结论大学生体重控制行为与体重心理控制源具有相关性,应帮助大学生树立正确的体重控制观点。

Objective To explore the relationships between weight-control behavior and weight locus of control among university students,and to provide reference for forming correct weight control conception. Methods A total of 1 504 undergraduate students of Zhejiang Province with weight-control behaviors questionnaire and weight locus of control scale. Canonical correlation analysis was used to analyze their relationships. Results Male college students scored higher than the female on the dimensions of diet,sports behavior and seeking external support（ P ＆lt; 0. 05）. For the first pair canonical correlation variables,they mainly reflect the relationships between external weight locus of control and seeking external support. For the second pair canonical correlation variables,they mainly reflect the relationships between occasional weight locus of control and diet. Two canonical correlation coefficients were statistically significant which were 0. 326 and 0. 126（ P ＆lt; 0. 01）,respectively. The cumulative contribution rate was 98. 4%. Conclusion The university students’ weight control behavior is correlated to weight locus of control. Some intervention should be taken to help them form correct consciousness.
