To improve mental health care for autistic adults, a better understanding of their real-world intervention use is required. The aim of this study is to investigate individual differences in the intervention trajectories of autistic adults, by examining longitudinal patterns of therapy, counseling, and medication use. Self-reported intervention use…

We investigate how context might influence adolescent boys' and girls' ambition and the impact of gender role conformity and social status. Adolescent participants (N = 270) reported their ambition in one of three experimentally manipulated contexts: future education, future work, or a control. Boys experienced a significant negative drop in…

Assessment and monitoring of safety in special education schools is imperative to establish and maintain a safe environment in which students can develop academic and social-emotional skills. The present study describes the development of a student self-report measure, the Safe at School questionnaire. Factorial validity, reliability and…

Camouflaging is hypothesized to play an important role in developing mental health difficulties. But this might not be true for everyone.

Student-teacher relationship drawings were employed to investigate how students' mental representations of student-teacher relationships were affected by their gender, age, and shyness across the Netherlands and China. The sample included 752 third- to sixth-graders (48.5% boys; M[subscript age] = 9.96) from the Netherlands and 574 third- to…

Pupils' subject choices at the level of secondary education critically determine the tertiary fields of study that they can pursue. This study used multinomial logistic regression models to investigate the extent to which the final report card grades of ninth-grade students predicted their choices of subject combinations at the senior general…

This exploratory study addressed this research gap. Students from a…
