New Service Protocol for Attention Deficit/Hyperactivity Disorder With Comorbidity: A Randomized Waitlist-controlled

The University of Hong Kong200 enrolled

Overview

The proposed study is to be carried out in 2021 - 2024 with youths aged 6 - 15 in Hong Kong. This is a randomized waitlist-controlled trial that aims to examine the effectiveness of the ADHD+ new service protocol. This ADHD+ new service protocol intervention will be delivered for 6 months in the format of groups by frontline social workers trained by professional clinicians including clinical psychologists and psychiatrists. It is designed to reduce ADHD and related symptoms in individuals aged between 6 and 15 years. Core treatment components include internet use/addiction intervention, cognitive training, emotion management, social skills training, occupational training, emotion support/befriending, parenting training, and career guidance. It is hypothesized that youths receiving the intervention will have reduced ADHD and related symptoms when compared with controls. Findings will allow the investigators to better understand the effectiveness of the new ADHD+ service; and in the long run, the service model can be generalized to community based early interventions for other uncomplicated mental disorders.

Interventions

The group-based intervention is designed to reduce participants' ADHD and related symptoms. The content of the treatment will follow an established manual which is developed by an expert group comprised of psychiatrists and clinical psychologists. Core treatment components include internet use/addiction intervention, cognitive training, emotion management, social skills training, occupational training, emotion support/befriending, parenting training, and career guidance. The main intervention lasts for 3 months, and the booster intervention lasts for another 3 months. The post- intervention assessments (3-month \[T1\], and 6-month \[T2\]) will be administered to all participants. During the period of intervention, all participants shall be clean from other forms of interventions to reduce any other possible confounders.

Outcomes

Primary Outcomes

The change of overall ADHD and related symptoms

Measured by Strengths and Weaknesses of ADHD-symptoms and Normal-behaviors questionnaire (SWAN) (for service users under 18 years old) (parent report). The scale has 18 items, each rated from -3 to 3 following 7-point Likert scale. Higher scores indicate greater symptomology

Time frame: From Time 0 (Baseline) to Time 1 (post-intervention 3-month) to Time 2 (post-intervention 6-month)

The change of difficult behavior in service users

Measured by Strengths and Difficulties Questionnaires (SDQ) \[children version\]. The scale has 25 items, each rated from 0 - 2. Higher score indicate more difficult behaviors.
