To study the influence of mediating/moderating effects of health skills on the relations between health knowledge and health behaviors in college students.
Stratified cluster random sampling was used among 2 181 students, selected in several colleges in Changsha, Hunan province. EpiData 3.0 was adopted to establish the database. Correlation and regression analyses were performed by SPSS 17.0.
Positive correlations were seen on: 1) Knowledge and skills on health (r = 0.592, P < 0.01), 2) Knowledge and behaviors on health (r = 0.647, P < 0.01), 3) Health skills and health behaviors(r = 0.629, P < 0.01). The mediating effect of health skills on the relations between health knowledge and health behaviors was significant (34.55%). The interaction effect of "health skill × (times) related knowledge" was significant (β = -0.093, t = - 5.212, P = 0.000). New variables that were produced by the interaction also reached significant level (Δ R(2) = 0.006, P = 0.000), resulted in increasing the explanation function to health behaviors by 0.6%.
Health skills could partially mediate the effects and moderate the relationship between health knowledge and health behaviors among college students.
探讨健康技能在大学生健康知识与健康行为关系中的中介/调节作用。
采用分层整群随机抽样法，选取湖南省长沙市多所高校的2181名学生。采用EpiData 3.0建立数据库。运用SPSS 17.0进行相关分析和回归分析。
发现以下方面存在正相关：1）健康知识与技能（r = 0.592，P < 0.01），2）健康知识与行为（r = 0.647，P < 0.01），3）健康技能与健康行为（r = 0.629，P < 0.01）。健康技能在健康知识与健康行为关系中的中介效应显著（34.55%）。“健康技能×（次数）相关知识”的交互效应显著（β = -0.093，t = -5.212，P = 0.000）。由该交互作用产生的新变量也达到显著水平（ΔR(2) = 0.006，P = 0.000），使对健康行为的解释功能提高了0.6%。
健康技能可部分中介大学生健康知识与健康行为之间的效应并调节二者关系。
