Supporting the Transition to Parenthood Through Online Sex and Relationship Knowledge

Becoming parents exerts powerful and long-lasting effects on couples' well-being and quality of life. The transition to parenthood (TtP; pregnancy to 12-months postpartum) poses significant challenges as couples balance the task of caring for a newborn while maintaining their romantic relationship. One crucial way that couples sustain their connection is through their sexuality. Sexual satisfaction is one of the top five predictors of relationship quality and is linked to lower perinatal anxiety, depression, and stress-all of which affect children's socioemotional development. Most new parents experience significant disruptions to their sexual well-being (i.e., sexual satisfaction, desire, distress), with sexual concerns such as reduced sexual frequency and lack of time and energy for sex being nearly ubiquitous. Simultaneously, most new parents lack easily accessible, reliable information on the common sexual changes associated with the TtP. Indeed, up to 78% of new parents report receiving little-to-no information about what to expect regarding changes to their postpartum sexual relationship. However, this information is fundamental to establish realistic expectations and to successfully manage the sexual changes likely to occur. There is a lack of evidence-based research aimed at helping couples navigate changes to their sexual well-being across this life transition. Studies that do exist are small, atheoretical, lack postpartum follow-up and typically focus on new mothers, neglecting partners' experiences as well as the interdependency of couples' sexuality. The investigators have identified risk (e.g., stress) and protective (e.g., intimacy) factors for couples' sexual well-being across the TtP that can be targeted in a prevention program, though no such programs exist.

The investigators have subsequently developed STORK (Supporting the Transition to Parenthood through Online Sex and Relationship Knowledge), a couple-based online program to support new parents' sexual well-being. STORK is rooted in scientific evidence drawn from our prior research identifying relevant protective and risk factors that are associated with changes in sexual well-being during the TtP. The program comprises psychoeducation about common sexual changes as well as skills that couples can develop together to manage these changes and constitutes the first evidence-based program for new parent couples' sexual well-being. The current study builds on a pilot study that found the STORK program was feasible and useful and supported the sexual well-being of new-parent couples from mid-pregnancy to 3-months postpartum.

The primary aim is to test the prediction that the STORK program will show efficacy in supporting the sexual adjustment of couples in the TtP, such that couples in the program group will report greater sexual satisfaction and desire and lower sexual distress at follow-up (4-months postpartum) and across the postpartum period (4, 8, and 12 months) relative to the control group. As the secondary aim, it is also predicted that couples in the program group will report better relational (i.e., greater relationship satisfaction and less relationship and sexual conflict) and psychological well-being (i.e., less symptoms of depression, anxiety) at follow-up (4-months postpartum) and across the postpartum period (4, 8, and 12 months) relative to the control group.

The investigators will (1) recruit an inclusive sample of 268 first-time expectant couples in their second trimester (13-27 weeks) of pregnancy; (2) randomize couples to either the STORK program or a waitlist control group; (3) have couples complete standardized, self-report measures at baseline (pre-program), 32-weeks gestation, 4-, 8-, and 12-months postpartum; (4) test the efficacy of STORK compared to the control group. Procedures will take place at Dalhousie University and the University of British Columbia.

This clinical trial addresses an important need for empirically validated, accessible, couple-based supports for the transition to parenthood-a time where couples commonly experience new sexual and relationship challenges. By strengthening couples' sexual relationships, the current research program has the potential to promote the quality of new parents' relationships, strengthening the overall well-being of their families during this critical life stage.
