Background

The COVID-19 pandemic has introduced or amplified stress and challenge within couples’ relationships. Among those who are particularly vulnerable to heightened conflict and lower relationship satisfaction during this time are interparental couples with young children, whose relationships may have already been tenuous prior to the pandemic. Stress within the interparental relationship may have ripple effects on all family subsystems and child adjustment. The Love Together Parent Together (L2P2) program is a brief, low-intensity writing intervention adapted for parents of young children that was designed to reduce conflict-related distress and prevent declines in relationship satisfaction. Based on an original writing intervention by Finkel and colleagues, L2P2 has adapted the intervention duration and study population to be appropriate to the current global context. This study will examine the key feasibility metrics related to this adapted program with the goal of identifying problems and informing parameters of future pilot and/or main RCTs.

Methods

The current study is a non-randomized feasibility study, using a single-arm, pre-test/post-test design to primarily assess the feasibility of an evaluative RCT, and to secondarily assess the potential effects on outcomes to be used in a future RCT. Couples will be recruited through three community-based agencies with the goal of obtaining a socio-demographically diverse sample. The first 20 couples to enroll will be included. Baseline and post-intervention surveys will be conducted, and a writing intervention will take place (three 7-min sessions over the course of 5 weeks). The primary outcomes will be feasibility metrics of recruitment rates, appropriateness of eligibility criteria, sample diversity, retention, uptake, adherence, and acceptability. In addition, we will develop an objective measure of couple “we-ness” based on an analysis of writing samples. The secondary outcomes will include couples’ measures (i.e., relationship quality, perceived partner responsiveness, self-reported responsiveness, conflict-related distress), and additional family outcomes (i.e., parent-child relations, parental/child mental health). Criteria for success are outlined, and failure to meet the criteria will result in adaptations to the measurement schedule, intervention design, recruitment approach, and/or other elements of the program.

Discussion

This feasibility study will inform several components of the procedures used for a subsequent pilot RCT, in which we will examine the feasibility of the methodology used to evaluate the program (e.g., randomization, attrition to follow-up assessment/across groups, and sample size estimation, preliminary effectiveness), as well as the main RCT, which will investigate the effectiveness of the intervention on primary outcome measures and mediating pathways.
