摘要:
运用计划行为理论对青少年休闲性体力活动进行检验与评估,为培养学生形成规律的行为习惯,并提出相应干预措施提供理论依据.方法 选取上海市353名7~15岁学生同时完成TPB量表调查和1周加速度器测量,分析青少年休闲性体力活动的影响因素.结果 青少年平均每天休闲性体力活动时间为(15.26±11.21) min,行为意向是青少年休闲性体力活动唯一直接影响因素,贡献率为8.9%.行为态度和感知行为控制联合预测行为意向33.2%的变异量,主观规范对休闲性行为和行为意向影响均无统计学意义.影响男生行为意向的重要因素是行为态度和感知行为控制,其贡献率为40.3%;影响女生行为意向的只有感知行为控制,其贡献率为27.4%.结论 我国青少年休闲性体力活动水平低于国外,计划行为理论对青少年休闲性体力活动的预测达到了中等影响水平.
Abstract:
Objective To evaluate the level of adolescents' leisure time physical activities,to examine and evaluate the participation of behavior theory,and to help students to foster healthy behaviors and to provide theoretical basis for further study in this field.Methods A total of 353 students aged 7-15 years old were selected to complete the questionnaires assessing the theory of planned behavior (TPB) constructs and acceleration measurements to analyze influencing factors of adolescents' leisure time physical activity.Results The average amount of adolescents' leisure time in moderate and vigorous physical activity(MVPA) was (15.26±11.21) min/d.Behavioral intention is the only direct factors accounted for 8.9%.Behavioral attitude and perceived behavioral control account for 33.2%.Subjective norms were not a significant predictor both in behavior and intention.Furthermore,intention among boys was predicted by their attitude and perceived behavior control (PBC),which accounted for 40.3%,whereas the sole predictor of intention among girls was PBC,which accounted for 27.4%.Conclusion Our adolescents' leisure physical activity level is lower than that of foreign teenagers.The analysis provided moderate support for the ability of the TPB variables to predict MVPA.
