小中学生における性別違和感の時間的安定性：6 年間の縦断調査による検討.

A challenge in dealing with gender dysphoria in children is the mixture of stable and temporary fluctuations in the feelings of gender dysphoria during development. This study examines the absolute and relative stability and the patterns of change of the feelings of gender dysphoria using data from a six-year longitudinal survey across three cohorts. The participants consisted of 2,031 people (999 boys and 1,032 girls) from fourth to ninth grades who completed the feelings of gender dysphoria scale. As a consequence of examining the changes in mean values by grade as absolute stability, the scores of boys slightly decreased from fourth to ninth grade; however, almost no significant change was found for girls. Latent profile analysis revealed 11 patterns including 22.6% of students who increased the score only within 1-2 years. The correlation between each grade as relative stability resulted in a positive correlation between each grade for boys and girls. In addition, the correlation coefficient increased as the grade increased, indicating that relative stability increased. The correlation coefficient was higher for girls than boys.
