FAB-Mx: Frontal Assessment Battery Scores for Parkinson's Disease Patients in Mexico

A Mexican Spanish adaptation of the Frontal Assessment Battery (FAB-Mx) for evaluating executive dysfunction in Parkinson's disease. The dataset contains psychometric validation results from a cross-sectional study of 124 participants, including 81 PD patients and 43 healthy controls. It was published by Dafne Vázquez Moreno on figshare in May 2026.

Use Cases

• Validate the FAB-Mx screening tool based on its reported psychometric properties like internal consistency and inter-rater reliability.
• Assess diagnostic accuracy for distinguishing cognitive impairment in Parkinson's disease based on the reported ROC curve analysis and cutoff scores.
• Correlate executive function scores with other neuropsychological measures like the Trail Making Test or Stroop test as described in the validation study.
• Evaluate the instrument's utility in resource-limited clinical settings based on its described brevity and diagnostic accuracy.

Strengths

• Dataset is openly licensed under CC-BY-4.0, permitting reuse with attribution.
• Validation study reports excellent inter-rater reliability (ICC = 0.96) and acceptable internal consistency (Cronbach's alpha = 0.65).
• Demonstrated discriminant validity with an AUC of 0.822 for distinguishing PD-MCI from healthy controls.
• Provides specific diagnostic cutoff scores (≤14.5 and ≤11.5) for clinical application.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to its single-country (Mexico) validation cohort.
