School-based non-pharmacological interventions are an important part of the treatment of attention-deficit/hyperactivity disorder (ADHD). We aimed to systematically review qualitative literature relating to the experience of and attitudes towards school-based non-pharmacological interventions for ADHD. Systematic searches of 20 electronic databases were undertaken. Reviewers screened titles, abstracts and full reports of studies, before extracting data and critically appraising 33 included papers. Studies were synthesised using meta-ethnographic methods. Four-key interrelated themes were identified: (1) individualising interventions, (2) structure of interventions, (3) barriers to effectiveness, (4) perceived moderators and impact of interventions. The perceived effectiveness of interventions used in school settings is reported to vary. Therefore, flexible, tailored interventions ought to hold potential. However, highly individualised interventions may negatively affect children with ADHD. Findings point to the need for school-based interventions to take into account the wider school context, as well as core symptoms of ADHD.
