Effectiveness of Nurse-Family Partnership on child outcomes by patterns of program intensity: Secondary evidence from a randomized controlled trial (British Columbia Healthy Connections Project)
Bibliographic record
Abstract
BACKGROUND: Nurse-Family Partnership's (NFP's) effectiveness at improving child outcomes is likely influenced by patterns of program provision and engagement, or 'intensity'. OBJECTIVE: To investigate program effectiveness by patterns of intensity. PARTICIPANTS AND SETTING: We analyzed secondary data from the Canadian NFP randomized controlled trial (RCT) involving 739 maternal participants and their 737 children in British Columbia. METHODS: Participants were randomly allocated 1:1 to NFP and existing services (n = 368) or existing services (n = 371). We collected data on child injuries, language, cognition and problem behavior (mental health) at age two years (by November 2019). We estimated principal causal effects (PCE) using propensity score (PS) methods. RESULTS: We identified three NFP intensity patterns: Low (median [Mdn] 14 visits), Partial (Mdn 52) and Sustained (Mdn 83). For NFP participants, we found statistically-significant differences in group mean scores (mean M [SD]): for Sustained on observed language (NFP 94.55 [16.71] versus PS-matched controls 89.97 [16.76]; PCE = 5.8, 95 % CI 0.57, 11.03, p = 0.030) and problem behavior (NFP 51.33 [9.04] versus PS-matched controls 56.43 [9.38]; PCE = -5.10, 95 % CI -8.27, -1.93, p = 0.002); and for Partial on maternal-reported language (NFP 313.43 [200.36]) versus PS-matched controls (255.99 [183.56]; PCE = 65.05, 95 % CI 24.09, 106.00, p = 0.013). CONCLUSIONS: Delivering NFP as intended, with sustained intensity, led to greater benefits regarding child language and problem behavior (mental health) but not cognition or injuries by age two years. These complementary analyses provide crucial information, beyond standard RCT analyses, on NFP's effectiveness in this Canadian cohort. Our results highlight the importance of ensuring full NFP intensity to maximize program benefits for children.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
