The purpose of this 12-month intervention program was to examine parent–child relationship changes within the sports context. A qualitative interpretative phenomenological analysis was used for the study design. Ten families consented to in-depth interviews. The participants were 10 youth sport parents who had one child each aged 5–6 years. The intervention program involved the participation of all the parents and children. The program integrated psychological, educational, and sports skills into pre-organized sports training sessions. The study results revealed that the intervention program had a positive impact on the parent–child relationship in the sports context. Additionally, the study results suggest that parental involvement in the intervention program positively affected parent–child attachment, the quality of interpersonal relationships between the parent and the child, and effective parenting strategies. Future intervention programs should include both parent and children dyads.
