About

This study will compare the effectiveness of combined parental stimulant medication and behavioral parent training (BPT) versus BPT alone on child ADHD-related impairment (primary outcome), child ADHD and externalizing symptoms, time to child stimulant prescription (secondary child outcomes) and parental ADHD impairment, parental ADHD symptoms, parenting, and BPT engagement (parental outcomes/target mechanisms). This study will also assess the care delivery context and develop an implementation approach for treatment of families with a parent with ADHD and a child with elevated ADHD symptoms via telehealth in primary care sites providing pediatric care.

Full description

Parental ADHD, present in 25-50% of families of children with ADHD and frequently untreated, interferes with effective parenting and predicts poor child developmental and behavioral treatment outcomes. Based on the literature and our own pilot data, the study will randomly assign parents with ADHD and their young at-risk children to one of two conditions: (1) stimulant medication for parents with ADHD followed by a child treatment strategy (CTS) beginning with behavioral parent training (BPT) with the added recommendation of child stimulant treatment if the child remains impaired or (2) a CTS without treatment for parental ADHD. The study will compare treatment effects on child ADHD-related impairment (primary outcome), child ADHD and externalizing symptoms, and time to child stimulant prescription (secondary child outcomes). The study will also examine target mechanisms including improvements in parental ADHD-related impairment and symptomatology (attention, impulsivity, emotional regulation), parenting skills, and BPT engagement, as well as treatment moderators (baseline parental ADHD severity, parental impairment, and parenting skills). Moreover, in an effort to develop a model of treatment that has potential for widespread dissemination while also reducing barriers to receiving care, the study will examine an implementation model involving parent ADHD screening in primary care followed by collaborative care delivered by co-located mental health providers via telehealth. Further, the investigators will develop an implementation plan and associated toolkit using a stakeholder participatory strategy to enhance the ability to move efficiently to adoption of this approach. In addition, the investigators will study the care delivery context, assessing procedures for and rates of screening and participation as well as staffing, workflow, provider- and patient-level acceptability, readiness, and feasibility of implementation approaches. This hybrid effectiveness-implementation project will be achieved via a collaborative R01 across 2 research sites in the US (N = 240 families), with 4-5 primary care partners at each site.

240 participants in 2 patient groups

Parent Stimulant Medication + Child Treatment Strategy

Experimental group

Description:

Parent stimulant medication first followed by a child treatment strategy consisting of behavioral parent training followed by a recommendation for child stimulant medication to the primary care provider if the child remains impaired.

Treatment:

Behavioral: Behavioral Parent Training

Drug: Extended release mixed amphetamine salts (MAS)

Child Treatment Strategy

Active Comparator group

Description:

Child treatment strategy consisting of behavioral parent training followed by a recommendation for child stimulant medication to the primary care provider if the child remains impaired. In this arm, parents do not receive stimulant medication before behavioral parent training.

Treatment:

Behavioral: Behavioral Parent Training
