Efficacy of a self-help parenting intervention for parents of children with attention deficit hyperactivity disorder in adjunct to usual treatment-Small-scale randomized controlled trial.

This study provides further support for self-help interventions as potentially low-intensity and cost-effective alternatives to therapist-led parenting interventions. The findings require replication in larger samples before any firm conclusions about adjunctive efficacy of NFPP-SH can be drawn but underline the potential for self-help within routine treatment (ClinicalTrials.gov Identifier: NCT02174952).
