  • Reliability and validity of Cognitive Abilities Test-Online for preschoolers and early school-age children

    Shikishima Chizuru, Inada Naoko, Akabayashi Hideo, Saneyoshi Ayako

    The Japanese journal of psychology (The Japanese Psychological Association)  96 ( 6 ) 417 - 427 2026

    ISSN  00215236

    　View Summary

    <p>This study aimed to develop the Cognitive Abilities Test Online (CAT-O) for preschoolers and early school-age children. The scale's reliability, validity, and factor structure were also investigated. The CAT-O consists of three subtests: the Picture Vocabulary Test-Online, the Visual Reasoning Test-Online, and the Visual Working Memory Test-Online. Study 1 revealed that each of the three tests demonstrated good test-retest reliability. In terms of convergent validity, the three subtests demonstrated moderate to high significant positive correlations with similar scales. In Study 2, confirmatory factor analyses of ordered categorical data with a national random sample (N = 1,251) revealed that the three-factor model was the best fit. The high internal consistency of each test provided further evidence of its reliability. The mean levels of individual correct response rates and categorical factor scores progressed according to grade level, which also confirmed the validity of the CAT-O. Future research should focus on investigating the usability of the CAT-O in research and clinical settings.</p>

  • Associations between daily parent–teacher communication, child's problem behavior, and parent–child relationship mediated by parental self-efficacy

    Fujisawa K.K., Nozaki K., Naoi M., Shikishima C., Akabayashi H.

    Early Childhood Research Quarterly 72   361 - 370 2025.07

    ISSN  08852006

    　View Summary

    This study investigated the role that daily communication between parents and teachers in childcare centers plays in enhancing parental self-efficacy, which in turn decreases the child's problem behaviors and improves the parent–child relationship. The data were drawn from 239 children (boys: N = 141; girls: N = 98; mean (SD) age = 4.95 (0.99) years) in formal childcare settings from the Japan Child Panel Survey-Preschool Survey. The results showed that daily communication between parents and teachers was positively related to parental self-efficacy, which was negatively related to child's problem behaviors and the conflictive parent–child relationship. Mediation analysis showed that parental self-efficacy mediated the association between parent–teacher communication and child's outcome and parent–child relationship. Furthermore, the association between parent–teacher communication and parental self-efficacy was moderated by socioeconomic status (SES), suggesting that higher-SES parents benefited more from daily parent–teacher communication compared with lower-SES parents. Child's daily experiences at childcare centers were not related to parental self-efficacy or any other outcomes. These findings suggest that daily communication between parents and teachers in childcare centers plays an indispensable role in supporting parents, which ultimately leads to positive child development and family well-being.

  • Relationship between Grit and Academic Achievement of Elementary and Junior High School Students: Genetic and Environmental Structure

    Yamaguchi Amane, Shikishima Chizuru, Kawamoto Tetsuya, Akabayashi Hideo, Ando Juko

    The Japanese Journal of Personality (Japan Society of Personality Psychology)  33 ( 3 ) 162 - 164 2024.12

    ISSN  13488406

    　View Summary

    <p>To examine the mechanisms underlying the relationship between academic achievement and grit, we divided grit into two dimensions: interest and perseverance. We explored these dimensions at the genetic and environmental levels using a behavioral genetic approach. The participants included 295 and 606 pairs of twins in elementary school and junior high school, respectively. At the phenotypic level, academic achievement positively correlated with perseverance across all school years. However, at the genetic and environmental levels, this relationship was shaped by environmental correlations among elementary school students and genetic correlations among junior high school students.</p>

  • Father’s Side or Mother’s Side? Lineage-Based Differences in the Impact of Grandparental Resources on Grandchildren’s Education in Japan

    H Takenoshita, K Nozaki, T Tamura, H Akabayashi

    Journal of Comparative Family Studies 55 (3), 290-320 55 ( 3 ) 290 - 320 2024.12

    ISSN  00472328

    　View Summary

    This study examines the mechanisms through which grandparental resources and advantages increase the opportunities of grandchildren to access college, using longitudinal data from Japan. It also focuses on the heterogeneity in the transmission of grandparental advantages by lineage and gender. Although recent studies of social mobility have increasingly recognized the accumulation of inequality across multiple generations, relatively few studies have identified the underlying mechanisms or explored the roles of extended family structures in shaping multigenerational mobility. To advance this line of inquiry, we investigate how grandparental resources and contact are associated with grandchildren’s college enrollment in Japan—a context characterized by strong intergenerational ties and mutual support. We draw on two key mechanisms to explain multigenerational social mobility: the contact-based and noncontact-based mechanisms. In addition, we examine variation by grandparents’ lineage and gender. Our findings show that contact with paternal grandparents and grandfathers on both sides facilitates the transmission of their advantages to grandchildren, whereas no such pattern is observed for maternal grandmothers. These results underscore the importance of contact with grandfathers and patrilineal lineages in shaping multigenerational mobility in Japan. This contrasts with studies based on U.S. data, which emphasize the role of grandmothers. To deepen our understanding of multigenerational mobility, future research should shed light on how grandparental contact and resources operate across diverse family and societal settings.

  • School ICT resources, teachers, and online education: Evidence from school closures in Japan during the COVID-19 pandemic

    H Akabayashi, S Taguchi, M Zvedelikova

    Education Economics 33 ( 4 ) 564 - 577 2024.06

    Research paper (scientific journal), Accepted

    　View Summary

    During the COVID-19 pandemic, schools switched to online education. Using Japan’s nationwide administrative data, we examine the impact of schools’ ICT equipment and teachers’ IT skills on the provision of online classes, communication with students’ families, and teachers’ working hours in early 2020. To isolate supply-side effects, we exploit differences in ICT resources between public elementary and junior high schools at a municipality level, the level at which ICT resources are decided. We find that basic ICT equipment was critical to implementing online classes, but IT skills were not. However, IT skills were associated with teachers’ working hours.

    　View Summary

    With regard to the effects of the new study support system for higher education on the promotion of the access to higher education to low-income eligible people, we clarified that it has a certain effect on promoting higher education by comparing the 2016 survey of parents of high school graduates and the survey of parents of high school graduates in 2020.
    With regard to the burden of educational expenses, a survey of parents of high school graduates showed that the opinion that parents should bear the burden has been consistently extremely strong since 2007. A similar trend was also revealed in a survey of parents of third-year junior high school students. In addition, the 2017 and 2023 national high school surveys compared the status of awareness of the student support system, and found that although awareness of the student support system has progressed in high schools since 2017, there is still a large information gap.

  • 長寿社会における世代間移転と経済格差： パネルデータによる政策評価分析

    2017.04

    2022.03

    Keio University, Grant-in-Aid for Specially Promoted Research, No Setting

    　View Summary

    本研究では、長寿社会と経済格差の関係に焦点を当て、長寿社会に起因する経済格差の発生メカニズム、さらには、経済格差が長寿社会での人々の暮らしや働き方、健康、社会経済の諸制度・政策、消費行動・生産行動、資産形成、結婚、出産などの家族形成、保育・教育などの次世代育成などに与える影響について、三世代の世帯（同居・非同居）を含む多様な家計を追跡するパネルデータの構築・解析を通じて多角的に研究する。
    本年度は、長寿社会における経済格差研究に関する理論的・実証的研究を整理・評価するとともに、家計パネルデータ等を用いながら各研究班で設定したテーマに沿って分析を進めた。また、昨年度に実施した「第二世代調査」（非同居の家族も含めた調査回答者の子世代への調査）のデータの解析も開始し、世代間の金銭的・非金銭的なつながりについて格差を関連付けた研究を進めた。各研究班の研究実績としては、論文５０本（うち査読付論文１６本）および図書６冊となっており、パネルデータなどを用いた経済格差のメカニズムや影響の解明を進めた。
    「日本家計パネル調査」については、本調査を実施するとともに「第二世代調査」の２回目の調査を実施した。また、本調査と第二世代調査では紙への記入による回答方法に加え、独自に作成したＷＥＢ画面による回答方法も提供し、回収率の向上につとめた。さらに、日本を代表するパネルデータとして、ルクセンブルク所得研究（LIS）への「日本家計パネル調査」や、オハイオ州立大学が指揮をとる国際パネルデータベースCross-National Equivalent File（CNEF）への提供を継続した。このほか、パネルデータの質の維持・向上のため、「日本家計パネル調査」の標本脱落やサンプル追加により発生するサンプリングバイアスの修正を行うウェイトの作成を欧州・豪州の専門家や家計パネルデータの設計・解析機関と連携して進めた。
    パネルデータなどを用いた経済格差のメカニズムや影響の解明については、昨年度に引き続き、積極的な研究を各研究班が実施し、計画以上の研究実績を積み上げている。「日本家計パネル調査」の３世代調査への拡張については、非同居の家族も含めた調査回答者の子世代へ調査回答者を拡げる形での新規調査を実施するとともに、単身高齢者世帯や地方在住者を含む新たな調査対象を追加することで、世界に先駆けた３世代調査への拡充が実現し、２回目の調査を実施したことで、パネルデータとしての利用ができるようになった。こうしたデータを用いた各研究班での研究も進捗している。さらに、新型コロナウイルス感染症の流行に伴って、「日本家計パネル調査」の回答者に郵送とＷＥＢによる特別調査を実施し、新型コロナウイルス感染症が家計にどのような影響を与え、格差がどのように変化しうるかを把握することを検討するなど、当初計画にない追加的な研究実施も議論している。
    パネルデータなどを用いた経済格差のメカニズムや影響の解明については、次年度以降も、パネルデータ等を活用して積極的な研究を各研究班が遂行するとともに、班リーダー会議や調査票策定会議、国内・国際ワークショップなどを通じた連携を研究班間で強めていく。また、OECDやオハイオ州立大学、EHESSなどの国際研究機関・大学等との共同研究を進めることで、グローバルな視点からの経済格差研究も強化する。「日本家計パネル調査」については、次年度以降も３世代調査として実施し、長寿社会における経済格差構造の解明につながりうるパネルデータとしての研究基盤の構築を進める。その際には、サンプルバイアスを補正するウェイトの作成・提供を進めるなどして、データのクオリティ面でもグローバルスタンダードを目指す。さらに、新型コロナウイルス感染症の家計への影響を把握するため、「日本家計パネル調査」の回答者に対する特別調査（郵送・ＷＥＢ調査）の実施も検討する。
