青年期前期における「親世代になることに対する意識尺度」の作成と信頼性・妥当性の検討

The Reliability and Validity of a Scale for Adolescent Awareness of Becoming a Parental Generation

要旨

　目的：青年期前期における親世代になることに対する意識尺度を作成し，信頼性と妥当性を検討する．

　方法：予備調査により48項目の尺度原案を作成した．A県内の高校生786名を対象に質問紙調査を実施し，内的整合性と構成概念妥当性を検討した．

　結果：回収数762名，有効回答数703名であった．因子分析及び信頼性の検討の結果，【子どもとの関わりに対する意識】【親子関係に対する意識】【親になることに対する意識】【夫婦や社会で子育てすることに対する意識】【子どもや子育てに対する関心・感情】【子育てに対する不安】の6下位尺度33項目で構成された．既知集団妥当性と確証的因子分析により，一定の構成概念妥当性が確保された．各下位尺度のCronbach's α係数は 0.76から 0.94で概ね良好な値が得られた．

　結論：作成した親世代になることに対する意識尺度の信頼性と妥当性は概ね確保できた．

　Objective: To construct a scale for adolescent awareness of becoming a parental generation and to examine the reliability and validity of said scale.

　Method: A preliminary survey was conducted to create a draft of a 48-item scale on awareness of becoming a parental generation. This survey was conducted on 786 high school students in four high schools in Prefecture A, and its internal consistency and construct validity were examined.

　Results: The number of responses collected was 762 (recovery rate: 96.9%); the number of valid responses was 703 (valid response rate: 92.3%). Following a factor analysis and an examination of reliability, a scale was devised with 33 items and 6 factors. The factors were as follows: “awareness of relationships with children,” “awareness of the parent—child relationship,” “awareness of becoming a parent,” “awareness of parenting with a couple and within society,” “interest and feelings regarding children / child care,” and “anxiety about parenting”. Known population validity and a confirmatory factor analysis ensured a constant level of construct validity. The Cronbach's alpha coefficient for each factor was generally good at 0.76 to 0.94.

　Conclusion: The reliability and validity of the scale for awareness of becoming a parental generation that was constructed in this study was generally confirmed.
