Abstract
【目的】ガイドラインに基づいた治療を受けている日本の気管支喘息児の養育者に特異的なQOL評価尺度を開発した.【方法】子供の喘息が養育者のQOLに与えている影響について無記名自記式質問票および面接により情報を収集し,二次調査票を作成した.そのデータを基にQOL尺度(QOLCA-24)を作成し,計量心理学的検討を行った.【結果】QOLCA-24の24項目に対する回答の因子分析により気管支喘息児の養育者QOLを構成する因子として11因子が抽出された.内的整合性αは,24項目全体では0.942であった.反復再現性を示すκ値は0.27〜0.53であった.因子1(子供の発作に伴う不安)および因子7(養育者の仕事への影響に対する負担)に属する質問で,喘息の悪化,改善による有意なQOLの変動が認められた.全般的健康尺度SF-8との相関がほとんどの質問項目で確認された.【結語】QOLCA-24は症状変化に伴う反応性および全般的QOLとの相関もありつつ,症状コントロールが良好となった昨今の喘息児の養育者QOLを多面的に評価できるツールとして有益であると考えられる.
Purpos: We developed the Health related QOL questionnaire which is specific for a caregiver of an asthmatic child, who has been treated based on JPGL (Japanese Pediatric Guideline for the Treatment and Management of Asthma). Method: Based on the answers collected anonymously or with interviews concerning caregivers' quality of life influenced by having children with asthma, the multipul choice secondary questionnaire was made. Through psycho-analytic procedures of the data from secondary survey 24-item questionnaire (QOLCA-24) has been developed. Result: Factor analysis revealed 11 factor structure of QOLCA-24. Internal consistency (cronbach α) of whole 24 items was 0.942. κ value which showed repetition plasticity was 0.27-0.53. The responsiveness associated with change of symptoms were significant in the items of factor 1 (Fear of asthma attack) and factor 7 (Job related burden of the caregiver). The score of most factors in QOLCA-24 were correlated with score of each item in SF-8. Conclusion: QOLCA-24 is thought to be useful as a tool to evaluate QOL of caregivers with asthmatic children.
