Objective To evaluate an online intervention for adults with ADHD that aimed to improve organizational skills and attention with the help of smartphone applications. Method Participants (n=57) were recruited and assessed through questionnaires and telephone interviews. Diagnoses of ADHD were confirmed for 83% of the participants, 5% most probably had the diagnoses, and 12% did not fulfill all diagnostic criteria despite high levels of symptoms. Participants were randomized between the intervention (n=29) and a wait-list control group (n=28). The 6-week intervention involved support from a coach in finding a routine for organizing everyday life with the help of smartphone applications. The primary outcome measure was ASRS Inattention. Secondary outcomes were ASRS sub-scale Hyperactivity and measures of depression, anxiety, stress, quality of life and general level of functioning. Blind evaluators also assessed improvement in organization and inattention at post treatment. Result The participants receiving the Living Smart course reduced their average scores on ASRS-Inattention from 28.1 (SD=4.5) to 22.9 (SD=4.3) which was a significantly larger reduction than found in the control group. 33% of participants were considered clinically significantly improved according to the blind evaluator, compared to 0% in the control group. The same results were found when only participants with a confirmed diagnose were included in the analyses. Conclusion Adults with ADHD seem to be able to use smartphone applications to organize their everyday life and can be taught how to do this via online interventions.
