Major depressive disorder and marital transition among mothers: Results from a national panel study
Bibliographic record
Abstract
This analysis employs a national panel study to examine the relationship between marital transition and depression among mothers within the framework of selection and causation processes. The data come from the two-wave, longitudinal National Population Health Survey (NPHS) by Statistics Canada collected in 1994 and again in 1996 focusing on women between 20 and 65 years of age with children living at home (N = 2169). Compared with mothers who remain married, mothers making the transition into single-parenthood had a significantly higher rate of major depression at Time 1, which increased, but not significantly, at Time 2. This suggests that a selection effect may explain the elevated levels of depression among mothers experiencing a marital disruption. Rates of depression among single-parent mothers making the transition into a marital relationship did not decrease significantly between waves nor did the rate differ significantly from stable single-parent mothers at Time 1 or Time 2, suggesting that movement into marriage is not a protective factor.

How this classification was reachedexpand
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.
