Thank You for Changing: Gratitude Promotes Autonomous Motivation and Successful Partner Regulation.

Romantic partners often attempt to improve their relationship by changing each other's traits and behaviors, but such partner regulation is often unsuccessful. We examined whether gratitude expressed by agents (i.e., partners requesting change) facilitates greater regulation success from targets (i.e., partners making change) by encouraging targets' autonomous motivation. Across studies, including observational (Study 1, N = 111 couples), preregistered longitudinal (Study 2, N = 150 couples), and experimental (Study 3a, N = 431; Study 3b, N = 725) designs, agents' gratitude for targets' efforts was linked to greater targets'-and less consistently agents'-reported regulation success. These effects were consistently mediated by greater target autonomous motivation, and generally persisted when accounting for how agents communicated their change request and other positive responses to targets' efforts (e.g., positivity and support). Gratitude for targets' efforts appears to be an important tool for promoting change success.

Dyadic coping and mental health in couples: A systematic review.

Globally, one out of three people suffer from a mental health issue during their lifetime. In romantic relationships, impaired mental health does not only affect the individual but also their partner and therefore needs to be coped with dyadically. In this systematic review, we summarize research examining dyadic coping (DC) in the context of mental health and individual and relational outcomes. We searched for peer-reviewed articles published between January 1990 and April 2023 on PsycInfo, Medline, and PSYNDEX on DC and mental health within romantic relationships. A total of 60 qualitative, quantitative, and intervention studies met the inclusion criteria, reporting on 16,394 individuals and 4,945 dyads. To synthesize the studies, we used a narrative synthesis approach. Overall, stress expression and positive DC yielded beneficial individual and relational outcomes, whereas, for negative DC, the opposite was true. Results differed between mental health clusters and context played an important role (e.g., symptom severity, life phase). Due to the great diversity of studies and variables, further research should focus on understudied mental health clusters (e.g., anxiety disorders). Clinicians are advised to view mental health issues as a dyadic rather than an individual phenomenon ("we-disease") and develop tailored couple-centered interventions.

Daily Sleep Quality and Support in Romantic Relationships: The Role of Negative Affect and Perspective-Taking.

Sleep is an important predictor of social functioning. However, questions remain about how impaired sleep-which is common and detrimental to affective and cognitive functions necessary for providing high quality support-is linked to both the provision and perception of support, especially at the daily level. We tested links between impaired sleep and provided and perceived support in romantic couples, and whether these links were mediated by negative affect and perspective-taking. In preregistered analyses of two 14-day diary studies (Study 1 N = 111 couples; Study 2 N = 100 couples), poor daily subjective sleep quality-but not duration-was associated with less self-reported support toward a partner (in both studies), less perceived support from a partner and less partner-reported support (in Study 1), and partner perceptions of receiving less support (in Study 2). Only greater daily negative affect consistently mediated the association between participants' impaired sleep (i.e., poor subjective sleep quality and duration) and their own support provision, as well as their partner's perceptions of received support. Our findings suggest that the effect of sleep on social processes may be strongest for self-reported measures of support and that unique aspects of sleep might be differentially associated with social outcomes given that sleep quality-but not duration-was consistently linked to support outcomes. These findings highlight the psychosocial influences of sleep and negative affect, and may inform approaches to promote supportive partner interactions.

The Benefits of Living With Close Others: A Longitudinal Examination of Mental Health Before and During a Global Stressor.

For better or worse, the people one lives with may exert a powerful influence on one's mental health, perhaps especially during times of stress. The COVID-19 pandemic-a large-scale stressor that prompted health recommendations to stay home to reduce disease spread-provided a unique context for examining how the people who share one's home may shape one's mental health. A seven-wave longitudinal study assessed mental health month to month before and during the pandemic (February through September 2020) in two diverse samples of U.S. adults (N = 656; N = 544). Preregistered analyses demonstrated that people living with close others (children and/or romantic partners) experienced better well-being before and during the pandemic's first 6 months. These groups also experienced unique increases in ill-being during the pandemic's onset, but parents' ill-being also recovered more quickly. These findings highlight the crucial protective function of close relationships for mental health both generally and amid a pandemic.

When We're Asked to Change: The Role of Suppression and Reappraisal in Partner Change Outcomes.

Receiving a request to change from a romantic partner can evoke intense emotional responses that hinder change progress and conflict resolution. As such, investigating how those being asked to change (i.e., change targets) regulate their emotions through key intrapersonal strategies (i.e., suppression and reappraisal) will lend crucial insight into promoting change success. Utilizing laboratory-interaction (Study 1; N = 111 couples) and experience-sampling methods (Study 2; N = 2178 weekly reports from an 8-week diary), we assessed targets' regulation strategies, change progress, and the extent to which they met their partner's ideals. Preregistered analyses demonstrated that targets' use of suppression was not linked to better or worse change outcomes. However, targets' use of reappraisal was linked to better change outcomes as rated by both partners. Additional analyses revealed that targets' suppression was linked to targets meeting their partner's ideals more in the short term but less over time, whereas targets' reappraisal was linked to targets meeting their partner's ideals more in both the short term and over time. These findings highlight reappraisal as a key strategy for promoting successful partner change.
