Conducting Evaluation Research with Hard-to-Follow Populations: Adopting a Participant-Centred Approach to Maximize Participant Retention
Bibliographic record
Abstract
Abstract: Longitudinal designs are effective for the evaluation of innovative social programs, but attrition can be a significant problem, particularly with hard-to-follow populations such as persons who are homeless. Tracking strategies for locating participants are essential, but retaining participants requires anticipating and addressing participants’ needs at every stage of the research. A strategy that emphasizes appropriate interviewer characteristics, the relationship between interviewer and participant, and participants’ “investment” in the research is critical. In other words, evaluation researchers can improve the retention of even hard-to-follow study participants by adapting research design and procedures to be “participant-centred.” An example is given of a program evaluation in Ottawa, Ontario, that implemented strategies to adapt to the needs of persons with severe mental illness and a history of homelessness.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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, unvalidatedLabeled directly by 3 models reading the full record.
