Physical inactivity and sedentary lifestyle are an emerging individual, familiar and social public health problem. The aim of this work was to validate a new questionnaire to know the attitude towards physical activity and other habits in adolescents.
The Delphi method was used. It was developed in three phases: an initial phase of selection of the panel of experts, an exploratory phase in two rounds of voting using a Likert scale of 1 to 5, and statistical and qualitative analysis of the experts' contributions. The criteria for the choice of items were: average >3.5 and factor V of Aiken ≥0.7. Reliability was assessed with the Cronbach alpha coefficient. A pilot test was carried out to assess the understanding of the instrument.
21 experts agreed to participate. Their participation was 100% in the first round and 95.2% in the second one. Seven items did not meet the criteria. The final questionnaire included 93 questions and 11 dimensions: data of the student, father, mother, physical activity in the educational center, transportation, free time, psychosocial aspects of physical activity, attitude towards physical activity, food, other habits and health perception. A Cronbach's alpha of 0.974 was obtained.
The results support the reliability and validity of the questionnaire. The Delphi method proved to be a useful technique for the proposed objective.
缺乏身体活动和久坐不动的生活方式正成为一个新出现的个人、家庭和社会公共卫生问题。这项工作的目的是验证一份新问卷,以了解青少年对体育活动和其他习惯的态度。
采用德尔菲法。该方法分三个阶段进行:专家小组选择的初始阶段、使用1至5的李克特量表进行两轮投票的探索阶段,以及对专家意见进行统计和定性分析。项目选择标准为:平均分>3.5且艾肯因子V≥0.7。使用克朗巴哈α系数评估信度。进行了一项预测试以评估该工具的易懂性。
21名专家同意参与。第一轮参与率为100%,第二轮为95.2%。7个项目未达到标准。最终问卷包括93个问题和11个维度:学生、父亲、母亲的数据,教育中心的体育活动,交通方式,空闲时间,体育活动的心理社会方面,对体育活动的态度,饮食,其他习惯以及健康认知。克朗巴哈α系数为0.974。
结果支持该问卷的信度和效度。德尔菲法被证明是实现所提出目标的一种有用技术。
