Families assigned to the active control group will participate in weekly "parent-child open house" where the parents will be permitted to meet with other parents in the meeting room and the children will be invited to attend an open gym. There will be no formal curriculum for the parent meetings, but the facilitator will be available to inform the parents of community resources (e.g., mentorship programs) and a resources table will be made available of community activities and referrals in the same manner as the other two groups.

The Nurturing Fathers program (Perlman, 2021) is an adaptation of the Nurturing Parent program. It is a 13-week program that covers the role of fathers, the importance of nurturance rather than fear in fathering, how to effectively play and discipline a child, how to build relationships with the child and co-parent, and it ends with a graduate ceremony. For the present study, consistent with a prevention approach, the investigators will modify the Nurturing Fathers program to focus on the content directly related to parenting skills. The investigators will implement an eight-week program, which is consistent with the duration of prior, successfully attended father-focused interventions (e.g., Fabiano et al., 2009).

The Nurturing Fathers program described above will be implemented as described. For the last 45 minutes of the sessions, fathers will join the child activity group and participate in shared parent-child activities consistent with the COACHES model. For the present study, several adaptations to the clinic-based COACHES program will be made, similar to those successfully deployed in our preliminary study in Head Start preschool settings (Caserta, Fabiano, et al., 2018). The investigators will use the Nurturing Fathers curriculum as the substantive content for each meeting, and then use the parent-child interactions within recreational sports as the forum for practicing skills.

Parent training on effective child management strategies

The Dyadic Parent Child Interaction Coding scheme will be used to assess parent behaviors (negative Talk, Indirect and direct commands, labelled and unlabelled praise) and child behaviors (Negative talk, compliance, noncompliance)

This is a measure of conflict resolution and tactics used between the male Completed by the caregiver and the child's other parent. Scores range from "This has never happened to More than 20 times in the past month. The scale measures frequency of behaviors from zero to more than 20 times. Higher scores indicate a worse outcome.

This is a measure of alignment in parenting practices. Answers range from strongly agree to strongly disagree on a five point scale. Scores range from 1-5, with lower scores indicating improvement.
