小児用Health Locus of Control尺度の信頼性，妥当性の検討

Validity and Reliability of the Children's Health Locus of Control Scale

要約

　多次元的Health Locus of Control尺度が小児の健康観を測定する尺度として広く用いられている．

　本研究では，10歳から15歳までの健常児および慢性疾患患児に小児用Health Locus ofControl尺度を適用し，信頼性と妥当性を検討した．

　項目分析，因子分析の結果，3下位尺度が抽出された．α係数は0.73～0.78，8週後の再テストではr＝0.74であった．妥当性については，健常児については尺度と保健行動，喘息児についてはセルフケア行動の相関係数は有意であった．これらの結果から信頼性，妥当性，構成概念妥当性は許容できるレベルであることが示された．

Abstract

　The Multidimensional Health Locus of Control (MHLC) scales have been widely used as a measurement of health beliefs in child populations.

　Studies were conducted with healthy and chronic physically ill children aged 10-12(primary school, 4th-6th grade) and13-15 (junior high school, 1st-3rd grade) to develop an instrument to measure childrens's health locus of control.

　An eight week study provided evidence that the MHLC has acceptable levels of reliability, (testretest reliability, r＝.74), internal consistency, (coefficient ranging from.73 to .78) and construct validity.

　Item analysis and factor analysis were performed to determine item effectiveness and existence of significant subscales.

　The main results concerning validity were as follows: Health behavior of healthy children was positively correlated with internal factors.

　Self-report with self-care behavior of children with bronchial asthma was positively correlated with internal factors.

　The results were discussed in reference to previous studies.
