Abstract
OBJECTIVE: Leisure time physical activity (LTPA) has been consistently associated with quality of life (QOL) in people with spinal cord injury (SCI). However, recent research suggests that intermediary variables account for the LTPA-QOL relationship in other populations. Using a prospective design, this study examined potential intermediary constructs linking LTPA and QOL in people with SCI. Drawing from previous literature, a longitudinal structural equation model was developed and tested to determine if depression, functional independence, social integration/participation, and self-efficacy mediate the LTPA-QOL relationship. METHOD: Participants (n = 395) were adults with SCI who reported engaging in at least some LTPA over an 18-month period. LTPA was assessed at baseline, the intermediary variables of depression, functional independence, social integration/participation and self-efficacy were measured at 6-months, and QOL was evaluated at 18-months. RESULTS: The structural model had minimally acceptable fit [χ²(395) = 803.16, p > .05; CFI = .90, RMSEA = .05 and SRMR = .06]. Baseline LTPA was related to functional independence (β = .20, p > .05), depression (β = -.32, p > .05) and self-efficacy (β = .60, p > .05) at 6 months. Six-month functional independence (β = .15, p > .05), social participation (β = .21, p > .05) and depression (β = -.34, p > .05) significantly predicted 18-month QOL. Only functional independence and depression were significant mediators. CONCLUSIONS: These results suggest that LTPA may improve QOL in adults with SCI through its influence on functional independence and depression.

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 it
