Trial Description

This study aims to pilot test an 8-week, self-administered dyadic (couples-based) positive psychology intervention for couples coping with stroke using a randomized, waitlist control design. Mood and well-being will be assessed pre- and post-intervention, and at 3-month follow-up. It is expected that both partners will demonstrate improvement in mood and well-being.

Detailed Description

Stroke survivors and spousal caregivers face significant challenges, yet interventions to support couples after stroke are largely lacking. Depressive symptoms post-stroke occur in 30-50% of survivors and partner caregivers, and have significant consequences on function and quality of life. Further, mood and psychosocial well-being are reciprocal in couples, meaning if one partner is depressed, the other is more likely to be depressed. Sustaining well-being in both partners is important for continued engagement in rehabilitation and re-integration into the community, yet existing interventions are aimed at the individual rather than the couple. This study will address this gap by testing an innovative dyadic (couples-based) intervention using a new approach based on positive psychology that focuses on the strengths in the relationship in order to foster resilience in the couple. Using a randomized waitlist control design, this pilot study aims to determine whether an 8-week dyadic positive psychology-based intervention (PPI) can improve mood and subjective well-being as assessed by established outcome measures in 24 couples coping with stroke. The intervention consists of self-administered PPI activities, such as expressing gratitude and practicing acts of kindness, which participants complete individually and as a couple. Two potential pathways will be explored for the PPI: (a) enhanced quality of interactions as couples deal with daily life demands and (b) improvements in mood that are "contagious" among couples. If found effective, couples with greater well-being may be better emotionally equipped to cope with the sequelae of stroke by reducing stress and depressive symptoms, and increasing participation in meaningful activities and quality of life.

Conditions

Interventions

  • Dyadic (couples-based) positive psychology intervention Behavioral
    Intervention Desc: Self-administered behavioral intervention in which participants complete at least 2 activities alone and 2 together each week for 8 weeks. Positive psychology activities include expressing gratitude, practicing acts of kindness, fostering relationships, working toward a goal, focusing on the positive, spirituality, and savoring.
    ARM 1: Kind: Experimental
    Label: Positive Psychology Intervention
    Description: Participants complete baseline assessments and receive a 20min training on the positive psychology activities. They are instructed to engage in at least 2 positive psychology activities alone and at least 2 as a couple each week for 8 weeks. Self-administered activities include expressing gratitude, practicing acts of kindness, focusing on the positive, fostering relationships, working toward a goal, spirituality, savoring. Post-intervention and 3-month follow-up assessments are completed.
    ARM 2: Kind: Experimental
    Label: Waitlist control
    Description: Participants complete a baseline assessment and are waitlisted for 4-6 weeks. They then complete another assessment, receive the 20min training on activities, and then complete the 8-week self-administered intervention (same as the experimental arm). Post-intervention and 3-month follow up assessments are also completed.
