MMG-FA was found to perform well in an extensive simulation study, but a larger sample size within groups is required for recovering more subtle loading differences. Its empirical value is illustrated for data on the social value of emotions and data on emotional acculturation.

Method Data from 5,233 couples in the English Longitudinal Study of Ageing were used to examine trajectories of physical activity, smoking, fruit and vegetable consumption, and alcohol use over a period of up to 12 years. Dyadic multilevel models examined patterns of change in each health behavior while allowing male and female partners to covary in intercepts, slopes, and occasion-specific residuals. The influence of perceived spousal support and relationship strain on each behavior was examined, adjusting for age, health, household income, and relationship length. Results Male and female partners reported similar initial levels of each health behavior and tended to show similar occasion-to-occasion changes as their partner. Higher spousal support predicted increased engagement in physical activity and fruit and vegetable consumption in men. Relationship strain appeared to be more impactful to female health behaviors, being associated with alcohol and tobacco use for female but not male partners. Conclusions Despite romantic partners reporting similar baseline healt
