MMAS-8 Psychometric Properties for Neuropsychiatric Disorders in Ecuador

440 Ecuadorian patients with neuropsychiatric disorders completed the Morisky Medication Adherence Scale (MMAS-8). José Alejandro Valdevila Figueira analyzed the scale's reliability, factorial structure, and convergent validity, supporting its use in clinical practice and research. The dataset contains psychometric properties comparing unifactorial and bifactorial models.

Use Cases

• Validate psychometric instruments for medication adherence based on the described Cronbach's alpha and McDonald's omega scores.
• Compare factor analysis models (one-factor vs. two-factor) based on the reported RMSEA, SRMR, CFI, and TLI fit indices.
• Assess internal consistency and item correlations for clinical scales based on the reported omega and correlation values.
• Support clinical practice decisions regarding adherence assessment tools based on the study's conclusion of reliability and validity.

Strengths

• Includes psychometric results from 440 patient responses, providing a substantial sample size.
• Reports specific fit indices (RMSEA=0.08, SRMR=0.06, CFI=0.92, TLI=0.90) and internal consistency metrics (α=0.70, ω=0.71) for the one-factor model.
• Compares two factor models, providing data for both unifactorial and bifactorial analyses.

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 the Ecuadorian sample.
