FFS（家族機能尺度）日本語版の開発―養育期の家族を対象とした信頼性と妥当性の検討

Development of the Japanese Version FFS（Family Functioning Scale）: Reliability and Validity for Family on Child-Fostering Phase

要旨

　目的：FFS（Family Functioning Scale）日本語版の信頼性と妥当性を検討する．

　方法：作成したFFS日本語版を用いて予備調査の後，3歳以下の乳幼児を養育中の母親501名を対象にFFS日本語版と属性からなる質問紙調査を行い，信頼性と妥当性を分析した．

　結果：FFS日本語版はFamily APGAR Scoreとの有意な正の相関（Spearman's ρ=0.63，p＜0.001）が見られた．因子分析の結果，6因子構造であることが確認され「情緒的絆と結束」「外部との関係」「家族規範」「役割と責任」「経済的資源」「コミュニケーション」と命名した．また全項目でのCronbach's α信頼性係数は0.90，下位尺度別でも0.70～0.86であり，内的一貫性が確認された．

　結論：FFS日本語版の家族機能尺度としての基準関連妥当性が確認された．また尺度の構造と信頼性が確認され，養育期家族の家族機能測定用具としての有用性が示唆された．

Abstract

　Purpose: This study examined the reliability and validity of the Japanese version FFS (Family Functioning Scale) for family on child fostering phase.

　Methods: FFS was developed in South Korea by Korean researcher. It consists of 24 items with a 4-point Likert scale ranging from strongly disagree to strongly agree. We developed a Japanese version of FFS in cooperation with Korean investigators. Then, 501 subjects were recruited randomly at nursery schools and during routine health examination for infant at community centers. Mothers with a child less than 3 years of age completed the questionnaire that consisted of FFS and data on family characteristics.

　Results: All of the data were analyzed statistically. In pretest, the Japanese version FFS has obtained positive correlation coefficient of 0.63 (Spearman's ρ, p＜0.001) with family APGAR score in pretest which was conducted among 250 adult men and women. In order to clarify the structure of FFS, factor analysis was performed. The result showed that the structure of FFS contained 6 factors (Affective bonding and unity, External relationship, Family norm, Role and responsibility, Financial resources, Communication) as same as Korean original version. Cronbach's alpha coefficient reliability score for all 24 items was 0.90, and also each factors reliability score were 0.70-0.86, confirming highly internal consistency.

　Conclusion: The Japanese version FFS was thought to be useful for assessing family function in Japanese families on child fostering phase.
