Love Together, Parent Together: A Protocol for a Pilot Study of an Intervention for Interparental Couples With Young Children (L2P2)

The COVID-19 pandemic has created a population-level threat to social relationships that requires a population-level solution. Among those who are particularly vulnerable to heightened conflict are interparental couples with young children, whose relationships may have already been under pressure prior to the pandemic. Reduced couples' satisfaction has been reported since the start of the pandemic, with over one-third of romantic partners reporting heightened conflict due to COVID-19. Couples are likely to stay in disharmonious relationships during times of socioeconomic upheaval, with the potential for relationship problems to persist over time. This may have serious implications for the mental health of parents, parent-child relationships, and children's emotional and behavioural problems (EBPs). Such a pattern is a societal concern given the known associations between couples' relationship quality and a number of critical indicators of population health, such as intimate partner violence, physical health and all-cause mortality, and economic instability, particularly for women. The current study protocol is for a pilot randomized controlled trial (RCT) of the Love Together Parent Together (L2P2) program-a brief, low-intensity, scalable relationship intervention for parents of young children. The two-arm (treatment vs. waitlist) pilot RCT will assess the feasibility goals: continued relationship-building with established recruitment partners and outreach to additional recruitment partners to increase enrolment rates; recruitment of a diverse sample in terms of sociocultural identity factors, pandemic-related stress, and relationship distress; acceptability of randomization; outcome assessment schedule completion (for treatment and control groups), retention and adherence to the program; and program acceptability. Additionally, the investigators will conduct a preliminary evaluation of treatment effects by examining group differences in couples-focused (i.e., couples' relationship, conflict-related negativity, interparental functioning) and family-focused outcomes (i.e., parent-child relations, parent mental health and child outcomes). A scalable couples-focused intervention is critically needed to circumvent the social consequences of the pandemic on young families.
