Longitudinal change in spousal similarities in mental health: Between-couple and within-couple perspectives.
Bibliographic record
Abstract
Research based on between-couple perspectives indicate that spouses share similarities in a range of psychosocial characteristics. In this study, the authors add to existing research by examining spousal similarities in mental health and its time-related change from both between-couple and within-couple perspectives. The authors apply latent growth models to 9-wave annual longitudinal data obtained from 3,410 adult couples in the Household, Income and Labor Dynamics in Australia Survey (HILDA; Mage wives = 48 years, Mage husbands = 50 years). In a first step, the authors corroborate extant findings from a between-couple perspective that spouses show considerable similarities in levels of and changes in mental health. In a second step, they calculate a within-couple similarity index (i.e., using absolute difference scores calculated based on the 2 partners' mental health). The authors show that mental health ratings between partners within a given spousal unit differed considerably (0.88 SD) and that these differences remained relatively stable over time. Examining between-couple differences in within-couple similarity revealed that larger discrepancies were associated with lower mental health (of individual partners), chronic health conditions, less marital satisfaction, and elevated risks for dissolution of the partnership. The authors discuss ways to integrate this counterintuitive set of findings with research originating from between-couple and within-couple perspectives, argue that a certain degree of spousal differences-if kept within certain bounds-can be adaptive serving developmental and relationship functions, and suggest routes for future inquiry on spousal similarities.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
