| 目的评价小学生7天体力活动问卷的效度和信度。方法采用专题小组讨论、观察、专家咨询等方法设计问卷。随机选取北京市城区4所小学的4～6年级小学生92名作为调查对象。采用重复实验评价问卷的信度,专家评价和Caltrac测量仪分别评价问卷的表面效度、内容效度和准则效度。结果问卷重复实验的结果之间的一致性较高,Kappa值在46.3%～78.9%之间,男生斯皮尔曼相关系数r值在0.66～0.87之间,女生的r值在0.57～0.82之间,P值均<0.01。问卷表面效度和内容效度较高,问卷结果与Caltrac测量仪结果之间在男女生中差异均无显著性,而且两种测量方法在男生中存在显著的正相关关系(r=0.46、0.38)。结论7天体力活动问卷能可靠地测量北京市城区4～6年级小学生的体力活动水平,能有效地测量4～6年级小学男生的体力活动水平 |
