Monitoring HIV Risk and Evaluating Interventions among Young People in Urban West Africa: Development and Validation of an Instrument
Bibliographic record
Abstract
We developed an instrument for HIV/AIDS behavioral surveillance applicable to youth living in urban West Africa. The instrument includes a comprehensive set of constructs borrowed from the sociocognitive theory of planned behavior as well as measures of parental and peer communication An exploratory (n=189) and validation sample (n=342) of young men and women living in Bamako were interviewed. Scale construct validity was assessed via factor analysis and multiple linear regressions and internal consistency was assessed using Cronbach's coefficient. All constructs had high internal consistency, scales' structure was relatively stable, and associations between different components of the questionnaire were in the predicted directions. Gender, sexual experience and education were significantly associated with attitudes and perception of control. Furthermore, attitudes, perceived behavioral control, perceived norms, and peer communication significantly predicted condom use. This questionnaire offers a valid and reliable tool for assessing young people's sexual behavior in an urban West African setting.

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.
