Adolescents' Love Lives: Heterogeneity in Relationship Status Trajectories and Links with Affect.

Romantic experiences are more fluid and heterogeneous during middle adolescence than at any other life stage, but current understanding of this heterogeneity and flux is limited because of imprecise measurement. A sample of 531 adolescents (55% female; 28% non-Hispanic White; 32% Black; 27% Hispanic; 14% Other) recruited from an ongoing birth cohort study (Mean age = 16.7 years, SD = 0.358), was administered bi-weekly diaries over 52 weeks to prospectively record transitions in and out of romantic and sexual relationships and to assess links with positive affect (frequency of happiness) and negative affect (frequency of sadness). Relationship statuses considered included not only dating, but also liminal and asymmetrical statuses such as talking/flirting and crushes. Latent profile analyses revealed six relationship status trajectories, or love life profiles, based on the number of intra-year partners and on the extent of involvement in each of the relationship statuses. Approximately half of teens either were in stable dating relationships or uninvolved romantically during the year; however, half experienced variable levels of flux in their love lives. Relationship instability, not romantic involvement per se, was associated with higher levels of sadness and lower levels of happiness. Snapshots of teen romantic involvement based on one or two points in time obscure the extent of relationship heterogeneity and flux and how relationship status trajectories are associated with positive and negative affect.

Adolescent Partnership Quality and Emotional Health: Insights from an Intensive Longitudinal Study.

Prior research has documented an association between adolescents' romantic experiences and poor emotional health. However, lack of intensive longitudinal measurement and an emphasis on negative affect have limited understanding about the extent to which adolescent relationship quality influences the emotional health of adolescents in partnerships, including the potential benefits of high-quality partnerships. Previous research has also been limited in its ability to account for factors that select adolescents into lower or higher quality partnerships. Using biweekly intensive longitudinal data from the mDiary Study of Adolescent Relationships linked to six waves of birth cohort data from the Fragile Families and Child Wellbeing Study, this paper uses multilevel mixed-effects models to address three questions: (1) How are changes in partnership quality (defined as validation, frequency of disagreements, and global quality) associated with changes in both positive and negative affect; (2) Do observed associations persist net of factors that potentially select adolescents into lower or higher quality partnerships (e.g., childhood family experiences); and (3) Do associations between partnership quality and affect differ by gender? Results show that higher quality partnerships are associated with both decreases in negative affect and increases in positive affect. There were no significant gender differences on average. The study's findings highlight the importance of partnership quality as a key source of temporal variation in adolescents' emotional states.
