ペンシルベニア州立大学の研究によると、子どもの精神的健康を左右する主な要因は、親がトランスジェンダーかシスジェンダーかといった性自認そのものではなく、育児ストレスの大きさであることが明らかになった。研究チームは、さまざまな家族構成の親子を対象に心理指標・家庭環境・ストレス度を分析し、親の性自認と子どもの抑うつ・不安・行動問題との間に体系的な関連は見られないと報告。一方で、親が高い育児ストレスや経済・社会的プレッシャーを抱えている場合、子どもの精神的健康が悪化する傾向が強かった。研究者は、子どもの幸福や適応力を高めるためには、ジェンダーに焦点を当てるのではなく、ストレス軽減・支援サービスへのアクセス改善が重要だと強調している。

子育てストレスが子どもの発達に与える影響を研究(Parenting stress, rather than parental gender identity, predicts child outcomes)

ABSTRACT

Social scientists know little about the experiences of transgender and nonbinary (TGNB) parents and their children’s development. In this study of 138 transgender parents (age M = 35.28 years; 86.2% White/European American) with binary (52.9%) and nonbinary (47.1%) gender identities, we explore the links between family processes and young children’s (age M = 6.30 years; 86.2% White/European American assigned female at birth = 47.8%) internalising and externalising behaviours. Bayes Factors suggested moderate to strong evidence that children’s development and family processes did not differ by parent gender identity. Many parents reported clinical levels of depressive symptoms. However, their children experience typical development despite high parental depressive symptomology. Parenting stress, not parent gender identity or depressive symptoms, was the only credible predictor of children’s externalising, internalising and total behavioural adjustment (M = 0.3; BF = 1.9e + 7; M = 0.3; BF = 1.1e + 7; M = 0.3; BF = 4.1e + 10, respectively). The implications of these findings are relevant to healthcare providers, legal experts and professionals who work with children and families and contradict the practice of citing unsupported and unfounded concerns that TGNB parents’ marginalised gender identity could harm their children’s functioning.

Summary
  • In a large, non-clinical sample of 138 families with transgender and nonbinary (TGNB) parents, we found that parenting stress—rather than parental gender identity or depressive symptoms—was the only credible predictor of children’s behavioral adjustment.
  • Our findings demonstrated that young children with TGNB parents showed typical psychological development, despite many parents reporting clinical levels of depressive symptoms.
  • These findings indicate that children’s well-being is more closely tied to family processes and dynamics, such as parental stress, than to a parent’s gender identity.
  • The implications of this study are relevant to healthcare providers, legal experts, and other professionals who work with children and families. Our findings directly contradict the practice of citing unsupported concerns that a TGNB parent’s gender identity could be harmful to their child’s functioning.
