초록

목적: 본 연구는 초등학생의 신체활동 정도를 사정할 수 있는 도구를 개발하기 위한 탐색적 연구이다. 방법: 본 연구는 도구개발과정과 예비조사(preliminary study)로 구분되어 있다. 신체활동의 구성요인 규명, 초기문항 작성, 내용타당도 검증, 최종도구 고안, 문항분석, 신뢰도 및 타당도 분석을 통해 총 41문항의 자가 보고식 설문지를 개발하였다. 예비조사는 서울시 소재 국공립 초등학교에 재학중인 초등학생 총 28명을 대상으로 이루어졌고 만보계와 Borg's scale을 이용하여 동시타당도 검증을 실시하였다. 결과: 예비조사 결과, 개발된 도구는 높은 내적 일관성을 보였고(cronbach's alpha=.89), 준거타당도를 위한 준거지표와의 Spearman correlation coefficient analysis에서는 만보계에 의해 측정된 도보수 (r=.69, p<.001)와 주관적 운동강도를 측정한 Borg's scale 점수(r=.76, p<.001)와 각각 양의 상관관계를 가지는 것으로 나타났다. 결론: 본 연구에서 개발된 도구는 초등학생의 신체활동 종류, 빈도, 강도 및 시간을 측정할 수 있도록 구성된 자가보고식 형태로 초등학생의 일상적인 신체활동을 측정할 수 있는 도구로 평가되었다. 비록 신체활동을 객관적으로 측정한 도구는 아니지만 신체활동 정도를 파악하기 위해 대규모 대상자에게 적용할 수 있는 실용적인 도구가 될 수 있을 것이다.

Objectives: This study is an explorative study for developing an instrument to measure habitual physical activity level of school-aged children. Methods: HPAQ-S consists of 41 items and a self-reported 5-day recall instrument designed to assess habitual physical activity level for school-aged children. For the validity and reliability test, a sample consisted of 28 children, aged 10-11 years old. Results: 41 question items showed an acceptable internal consistency (cronbach's alpha=.89). A significant positive correlation with the pedometer results (r=.69, p<.001) and with Borg's questionnaire (r=.76, p<.001) support the validity of HPAQ-S. Conclusion: HPAQ-S may be more useful for measuring habitual physical activity level of elementary school-aged children in large populations.
