My career interests lead me towards an avocation in psychometrics science and research methods. I aim to be deeply involved in enhancing the quality of psychometric measurements to provide researchers with improved research instruments. Co-author of academic works contributing to: Content validity: Aiken's V with Confidence Intervals for Attitude Scales; Reliability coefficients: Cronbach's Alpha and McDonald's Omega; Internal Structure Validity: Exploratory Factor Analysis and Confirmatory Factor Analysis; Construct validity (convergent and discriminant): AVE and inter-factor correlation analysis; Measurement invariance for first and second order models: configural, metrical, scalar, and strict; Evidence of validity relative to other constructs: SEM; Structural Equation Modeling (SEM).
