Plain English Summary
Background and study aims
Attention deficit hyperactivity disorder (ADHD) is a common childhood disorder in which the sufferer struggles with attention, impulsivness and hyperactivity. Almost all treatments for ADHD have been adjusted for treating children or adults, and little research has been done to evaluate their effectiveness in adolescents. Adolescence is a time involving rapid physical, mental and social development takes place, which can lead to feelings of inner turmoil, emotional instability and negative mood. Adolescents with ADHD have a high risk of experiencing problems in development in these areas because of issues with being able to manage disruptive emotions and impulses. PowerCoaching is an ADHD treatment specifically designed for adolescents. The aim of this study is to evaluate the effectiveness of this treatment.
Who can participate?
Adolescents with ADHD between the ages of 12 and 18 years old.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group receive PowerCoaching immediately. This involves sessions at the participant's home every week for 18 weeks. The sessions last for about an hour and involve discussions about a range of topics and the teaching of stratagies to help cope with ADHD related problems. Those in the second group receive treatment as usual for the 18 weeks of the study. Participants in both groups complete a number of questionnaires at the start of the study and then again after 18 weeks. After participants in both groups are assessed, participants in this group are able to take part in the PowerCoaching, but no further measurements are taken.
What are the possible benefits and risks of participating?
The coaching program may benefit participants in helping them to cope with daily problems related to ADHD and improve their quality of life. There are no notable risks involved with taking part in the study.

Attention deficit hyperacitivty disorder (ADHD) and problems in daily functioning
Adolescents are randomized to one of two groups:
Immediate treatment group: Participants receive the PowerCoaching for a total of 18 weeks. Sessions are given once a week at the participant's home, lasting for 45 to 60 minutes, and involve the discussion of different themes (i.e. psycho-education, planning and organisation, school and study, self-image, emotion regulation, relations, risk and control and lifestyle). During the sessions, participants will learn new strategies to cope with ADHD related problems.
Delayed treatment group: For the 18 week duration of the study, participants continue as usual. Following collection of the final outcomes, the treatment is made available from week 19 to week 37.
Participants in both groups complete outcome measurements at baseline and 18 weeks.
Primary outcome measure
Quality of life is measured using “Weiss Functional Impairment Rating Scale (WFRIS) excluding the subscale ‘work’ at baseline and 18 weeks.
Secondary outcome measures
