Abstract

Introduction: This systematic review and meta-analysis assessed the characteristics, types, and impact of interventions to improve adherence to attention-deficit hyperactivity disorder (ADHD) medications within the context of the three phases of adherence, namely, initiation, implementation, and discontinuation.

Methods: PubMed, Psychological Information Database, Embase, International Pharmaceutical Abstracts, and Google Scholar were systematically searched for relevant trials using appropriate search terms. Interventions were classified as educational, behavioural, affective, and multifaceted. Data was pooled using odds ratios and proportions.

Results: Seventeen studies were included in this review. In a pooled analysis of four RCTs, interventions did not significantly improve medication adherence (OR = 2.32; 95%-Confidence Interval=CI = 0.91–5.90; p = 0.08). In seven non-randomized trials, a pooled proportion of people who adhered to ADHD medication was considerably higher in the intervention group (85%, 95%CI = 78%-91%) than in the control group (47%, 95%CI = 33%–61%). Interventions varied in terms of study design, methods and their impact on different phases of adherence.

Conclusions: Despite some promising results, the lack of consideration of phase-specific adherence factors may limit the effectiveness and sustainability of interventions to improve adherence in clinical practice. Future interventions should be phase-specific, guided by factors which are pertinent to each phase. Meanwhile, clinicians should choose or tailor interventions based on individual needs and preferences.
