    Abstract

    In Japan, many fathers consider their spouse to be their children’s primary parent while casting themselves in a supporting role. Yet, in the majority of reported child maltreatment cases in Japan, the child’s father is recorded as the perpetrator. This may seem somewhat puzzling, given that primary caregivers are recorded as the perpetrator of maltreatment in other cultures. This study qualitatively analyses the parenting experience of 11 Japanese fathers and their reflections on child maltreatment risks. Semi-structured interviews were conducted with fathers of pre-school aged children from middle-class families who had no reported history of child maltreatment. Using qualitative content analysis through a process of condensing, coding and categorising, we arrived at the following theme: fathers aspire to be an active parent, while respecting and supporting their spouses, but anxiety and stress trigger impatience and frustration during parenting. The fathers reported that they are more likely to maltreat their children, especially boys, in situations which triggered anxiety and frustration. Anxiety is particularly heightened when they feared public embarrassment. These findings are discussed with reference to the Japanese social and cultural context, and contrasted with previous research into the parenting experiences of Japanese mothers. The findings indicate that fathers may benefit from tailored support programmes which strengthen their self-efficacy before building resilience for the challenging situations they may encounter as fathers.

    本研究は国際・学際横断的連携により、しつけと虐待の線引きの困難さ、複雑さ及び文化間、社会間での差異を念頭におきつつ、3つの研究で構成される。研究１・２では「ナラティブからとらえる、虐待の境界に存在する子育て期女性の育児実践」をトリアンギュレーションの視点を加味して、日本および英国で調査する。これらの調査は、多分野の博士号を持った研究者らが学際的に知見を統合し、分析する。研究３では文化的および社会的背景が大きく関与する虐待の閾値に関連する子育ての価値体系について、質的比較分析によって国際比較する。
    本研究の目的は国際・学生横断的連携により、しつけと虐待の線引きの困難さ、複雑さ、および文化間、社会間での差異を念頭に起きつつ、虐待に移行させない子育て支援モデルと構築することである。
    令和3年度は日本と英国での倫理審査の申請および許可、日本と英国でのインタビュー調査を行った。現在はインタビュー調査を進めつつ、得られたデータを分析している最中である。

    　View Summary

    本研究の目的は、治療を受ける子育て世代のがん患者が抱える気がかりに対するアセスメントツール、及びアプリケーションを開発し、評価資料に基づくITを活用した包括的ケアモデルの開発を行うことである。
    2019年度は、前年度に準備を進めたインターネット調査を実施予定であったが、研究参加候補者の選定に時間や調整を要した。必要回答数が得られない状況になったため、調査項目の見直しや研究参加者のリクルート方法について再検討を行った。
    その結果、質問項目の多い関連探索研究ではなく、因子探索研究から取り組み、開発するケアモデルの対象となる患者の気がかりや子供の発達段階などを焦点化を行うこととなった。調査項目は、既存の研究を参考に、患者の基本属性(子育て中の子どもの属性含む)、子育て状況、子育てに伴う情緒的反応(喜び、悩み、負担)、子育て中の困難と対処、希望する支援とした。困難や希望する支援については自由記載とし、質的データを得ることでがん患者が抱えている気がかりの具体を明らかにすることとした。なお、研究参加に伴う負担に配慮し、質問項目は25項目程度にとどめた。また、リクルート方法については、複数の患者団体へ依頼をする計画を進めていたが、COVED-19の影響を鑑み、インターネット調査会社に登録している者へ依頼することとした。
    現在は委託業者と調査準備を進めているが、今後は倫理審査委員会への申請、承認を受け実施予定である。

  • Development of the Parents' Discipline Self-Triage Scale and the Construction of a Comprehensive Support Care System for the Parenting Generation.

    　View Summary

    The purpose of this study is to develop a scale that allows parents who are troubled by discipline to triage the degree of danger by themselves. In the interview study with fathers, the attributes of the child, the physical condition of the parent, and the child's crying were possible triggers as factors that could turn into abuse. Besides, we integrated the findings to date and developed the Mother and Father Discipline Self-Triage Scale.

  • Aspects of the boundary between discipline and abuse by mothers raising preschool age children

    　View Summary

    To analyze and clarify aspects of the boundary between discipline and abuse by mothers raising preschool age children based on analysis of narratives regarding parenting behaviors.Semi-structured interviews were conducted on 26 mothers raising preschool-age children focusing on the experiences they considered to reflect the boundary between discipline and abuse. Interview transcripts were qualitatively analyzed using a modified grounded theory approach.
    Categories reflecting aspects relating to the boundary between discipline and abuse were extracted as follows: “power to overwhelm the child unconsciously when their mother becomes emotional” and “differences in discipline depending on the attributes of the child”. Additional categories included “superiority of other people’s appraisal of discipline”; “accumulated fatigue from idealized images and responsibilities as a mother”; and “peace of mind to change according to surrounding support and mother’s capabilities”.
