Abstract
Abstract Background The Subjective Memory Complaint Scale (SMCS-15) is a 15-item instrument to explore frequent forgetfulness in daily life in people with possible cognitive impairment. However, knowledge about its psychometric performance is limited. Objective To know the dimensionality and internal consistency of the SMCS-15 in Colombian older adults. Methods A probabilistic sample of 1,957 older adults from the general Colombian population was taken, aged between 60 and 98 years (mean = 71.0 ± 7.9), and 62.2% were women. Internal consistency (Cronbach's alpha and McDonald's omega) and dimensionality (exploratory and confirmatory factor analysis) were calculated for the original and ten-item versions. Results The 15-item version showed Cronbach's alpha and McDonald's omega of 0.91 and one dimension that accounted for 45.3% of the variance. A version of ten items showed Cronbach's alpha and McDonald's omega of 0.89 and a single factor that explained 50.9% of the variance with better indicators in the confirmatory factor analysis. Convergence with the shortened Mini-Mental State Examination was r s =0.43 (p < 0.001), and the Montreal Cognitive Assessment test was r s =0.38 (p < 0.001). The nomological validity with the geriatric depression scale was r s =0.44 (p < 0.001), and women scored higher than men (p < 0.001). Conclusions The SMCS-15 shows high internal consistency with poor dimensionality. However, a ten-item version shows high internal consistency and a clear one-dimensional structure. More research is needed.

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
