The Marriage Checkup: A randomized controlled trial of annual relationship health checkups

OBJECTIVE This study assessed the efficacy of the Marriage Checkup (MC) for improving relationship health and intimacy. METHOD Cohabiting married couples (N = 215, Mage women = 44.5 years, men = 47 years, 93.1% Caucasian) recruited from a northeastern U.S. metropolitan area through print and electronic media were randomly assigned to MC treatment or wait-list control. Treatment but not control couples participated in assessment and feedback visits, at the beginning of the study and again 1 year later. All couples completed 9 sets of questionnaires over 2 years. Outcome measures included the Quality of Marriage Index, the Global Distress subscale of the Marital Satisfaction Inventory-Revised, the Intimate Safety Questionnaire, and the Relational Acceptance Questionnaire. RESULTS A latent growth curve model indicated significant between-group differences in intimacy at every measurement point after baseline (d ranged from .20 to .55, Md = .37), significant between-group differences in womens felt acceptance for every measurement point after baseline (d ranged from .17 to .47, Md = .34), significant between-group differences in mens felt acceptance through the 1-year 2-week follow-up (d across follow-up ranged from .11 to .40, Md = .25), and significant between-group differences in relationship distress through 1-year 6-month follow-up (d across follow-up ranged from .11 to .39, Md = .23). CONCLUSIONS Longitudinal analysis of the MC supports the hypothesis that the MC significantly improves intimacy, acceptance, and satisfaction. Implications for dissemination are discussed.

Pilot Randomized Evaluation of Publically Available Concussion Education Materials Evidence of a Possible Negative Effect

Many states and sports leagues are instituting concussion policies aimed at reducing risk of morbidity and mortality; many include mandates about the provision of concussion education to youth athletes. However, there is limited evidence if educational materials provided under these typically vague mandates are in fact effective in changing concussion risk-related behavior or any cognition predictive of risk-related behavior. The purpose of this pilot randomized controlled study was to conduct a theory-driven evaluation of three publically available concussion education materials: two videos and one informational handout. Participants were 256 late adolescent males from 12 teams in a single league of ice hockey competition in the United States. Randomization of educational condition occurred at the team level. Written surveys assessing postimpact symptom reporting behavior, concussion knowledge, and concussion reporting cognitions were completed by participants immediately before receiving their educational intervention, 1 day after, and 1 month after. Results indicated no change in any measure over any time interval, with the exception of perceived underreporting norms. In one of the video conditions, perceived underreporting norms increased significantly 1 day after viewing the video. Possible content and viewing environment-related reasons for this increase are discussed. Across all conditions, perceived underreporting norms increased 1 month after intervention receipt, raising the possibility that late in the competitive season underreporting may be perceived as normative. The need for the development of theory-driven concussion education materials, drawing on best practices from health behavior scholars, is discussed.

The heart of change: Acceptance and intimacy mediate treatment response in a brief couples intervention.

In this study, we examined mediators of a brief couples intervention. Intimate safety, acceptance, and activation were examined in 2 roles: their contribution to marital satisfaction gains in the first 2 weeks after treatment (contemporaneous effects), and how early changes in the mediators influenced longer term changes in marital satisfaction over 2 years of follow-up (lagged effects). Married couples (N = 215) were randomized to either an intervention group or a wait-list control group and followed for 2 years. Latent change-score models were used to examine contemporaneous and time-lagged mediation. A booster intervention in the 2nd year was used for a replication study. Changes in intimate safety and acceptance were uniquely associated with contemporaneous treatment effects on relationship satisfaction in Year 1, but only acceptance was uniquely associated with contemporaneous effects in Year 2. With respect to lagged effects, early changes in acceptance partially mediated later changes in marital satisfaction in Year 1, whereas the same effect for intimate safety was marginally significant. These lagged paths were moderate in size and indirect effects were small. No lagged effects were significant in Year 2. Change in activation was not significant as either a contemporaneous or a lagged predictor of change in relationship satisfaction. We found moderate support for acceptance and more limited support for intimate safety as mediators of short- and long-term treatment response, suggesting that these processes play an important role in sustaining marital health.
