Validation of the Episodic Disability Framework with adults living with HIV
Bibliographic record
Abstract
Purpose: To assess the validity of dimensions of disability in the Episodic Disability Framework, a conceptual framework derived from the perspective of adults living with HIV. Methods: We conducted confirmatory factor analyses with 913 adults living with HIV in an observational cohort study called the Ontario HIV Treatment Network Cohort Study (OCS). We tested hypotheses that dimensions of disability in the Episodic Disability Framework were represented by a group of measured variables in the observational database. Results: A model comprised of four latent variables and 43 indicator variables with one cross-loading was superior to models with fewer latent variables and more indicator variables and supported the validity of disability dimensions: physical health symptoms (represented by 21 indicator variables), mental health symptoms (10 variables), difficulties with day-to-day activities (5 variables) and challenges to social inclusion (8 variables). Overall goodness of fit statistics were χ(2 )= 2621.50 (p < 0.001), Comparative Fit Index = 0.912, Tucker Lewis Index = 0.907 and root mean square error of approximation = 0.048. Dimensions of disability correlated with each other ranging from r = 0.44 (between physical symptoms and challenges to social inclusion) to r = 0.81 (between physical symptoms and difficulties with day-to-day activities). Conclusions: This study supports the validity of four disability dimensions in the Episodic Disability Framework. This framework provides a new way to conceptualize disability and can lay the foundation for developing a future HIV disability measure for clinical and health services research. Implications for rehabilitation: The Episodic Disability Framework is the first known conceptual framework of disability developed from the perspective of adults living with HIV. Results from this confirmatory factor analysis support the validity of four dimensions of disability experienced by adults living with HIV in the Episodic Disability Framework including: physical symptoms and impairments, mental health symptoms and impairments, difficulties carrying out day-to-day activities, and challenges to social inclusion. The Episodic Disability Framework provides a new way to conceptualize disability experienced by adults living with HIV. Clinicians can use this Framework to better understand episodic disability experienced by adults living with HIV. Clinicians can frame their assessments of disability to include physical and mental health symptoms and impairments as well as consider a patient's ability to participate in society, and indicate areas to apply interventions or strategies to prevent or mitigate disability experienced by adults living with HIV.

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.
