Pilot Study of the Parental Friendship Coaching+ Program for Families of Children With Attention-deficit/Hyperactivity Disorder

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.

Inclusion criteria

Parents who participate in this study must meet the following criteria:

• have a child (age 6-11) with elevated ADHD symptoms and peer difficulties;
• have at minimum subclinical levels of depression and/or ADHD determined by self-report on symptom measures (parents with clinical levels are eligible);
• be the primary parent involved with the child and their social life.

Exclusion criteria

Parents will be excluded if:

• they cannot understand or speak English at a 9th grade level as they will be unable to participate in PFC+ (delivered in English) or complete questionnaires (reading/writing at the 9th grade level is not required as parents can be provided support in reading questionnaires and PFC+ content is delivered verbally);
• they require alternative supports for more pressing mental health concerns (such that it would not be in their best interest to delay those other supports in order to participate in the current study), this might include schizophrenia, psychosis, a personality disorder, autism, intellectual disability, suicidal ideation, or self harm (they will be referred to alternative supports as needed);
• they are participating in a different BPT program at the same time as they are projected to participate in PFC+;
• if their 6-11 year old child has autism, pervasive developmental disorder, diagnosed or suspected intellectual disability, psychosis, or active suicidality (they will be referred to alternative supports as needed);
• if their child does understand or speak English at the 1st grade level, as they will need to complete some questionnaires (research assistants will support children through questionnaires so reading at a 1st grade level is not required);
• they do not have access to a computer, internet, and a private space to attend sessions (as the sessions are online, and a private space is needed to protect the confidentiality of other study participants).
