Behavioural parent training (BPT) is a front-line treatment for children with attention-deficit/hyperactivity disorder (ADHD) that teaches parents how to support their child and manage behaviour. Parents of children with ADHD who have their own elevated ADHD/depressive symptoms may be less likely connect/engage and benefit from BPT. The current study modifies a BPT program that specifically addresses peer difficulties as these are common in children with ADHD. The goal of the modifications is to enhance the treatment process (how much parents connect and engage with the treatment) for parents with elevated ADHD/depressive symptoms. The Investigators will test whether this intervention increases parent engagement/connection to the program and whether it improves parenting behaviour.


Study Purpose: The aim of this study is to conduct a pilot of PFC+ (a modified version of Parental Friendship Coaching), a BPT program for parents of children with ADHD and peer difficulties. Dr. Mikami created PFC and has conducted a randomized controlled trial comparing PFC to a psychoeducation/social support group. The investigators have modified PFC for parents with elevated ADHD and/or depressive symptoms to encourage engagement and connection with the program with the goal of improving eventual outcomes for these families. The reason why this modification was done is because parents with elevated ADHD and/or depressive symptoms typically do not benefit from BPT as much as parents without elevated symptoms. The current study examines the potential benefit of such modifications for these populations.

Hypothesis: The first hypothesis is that parents who participate in PFC+ will engage well with the program (attend, complete homework) and will report feeling connected to the program (satisfied with treatment, alliance with therapist, social support from parent peers). The second hypothesis is that participation in PFC+ will be associated with improvement in parenting related outcomes (parenting behaviour, parent stress, parent sense of competence), both over time and relative to a waitlist control condition.

Study Population: Participants will be families of children between the ages of 6-11. The parent will have elevated ADHD or depressive symptoms and will participate in the treatment and complete questionnaires and interviews. Children will have elevated ADHD symptoms and peer difficulties, and will complete questionnaires about the parent's parenting style. A co-parent will also be recruited, and can be anyone who can provide another perspective on the parent's parenting style (e.g., romantic partner, grandparent of the child); co-parents will complete questionnaires about the parent's parenting style.

Research Method: The investigators will recruit 48 parents to participate in the pilot of PFC+ and will use a crossover design so that all parents have the opportunity to participate in PFC+. In the eligibility screening, the parent will complete questionnaires about their symptoms and their child's symptoms to determine eligibility. At timepoint 1 (T1), all eligible families (parent, child, co-parent) will complete initial questionnaires to collect data about baseline functioning. Parents will be randomized to participate in PFC+ or a waitlist control condition (6 parents in each condition). PFC+ parents will then complete the treatment program over 5-6 weeks, while the waitlist parents will continue life as usual for 5-6 weeks. After PFC+ completes, all families will complete timepoint 2 (T2) questionnaires. Following this, crossover will occur, where parents in PFC+ will enter a naturalistic follow up, and parents previously in the waitlist condition will begin PFC+. Once treatment has finished (another 5-6 weeks), all families will complete timepoint 3 (T3) questionnaires.
