Hamilton Rating Scale for Anxiety: exploring validity with robust measures of classical theory parameters and a rating scale model in university students.

ABSTRACT:

Background

No research has assessed Hamilton Rating Scale for Anxiety (HRSA) psychometric properties in Ethiopian university students, using item response theory (IRT) and classical theory.

Aims

This study aimed to assess psychometric properties of the English HRSA in Ethiopian students, using IRT and classical theory.

Method

University students (N = 370, age 21.44 ± 2.30 years) in Ethiopia participated in a cross-sectional study. Participants completed a self-reported measure of anxiety, a sociodemographics tool and interviewer-administered HRSA.

Results

Confirmatory factor analysis (CFA) favoured a one-factor structure because fit indices for the one-factor model; and two distinct two-factor models were similar, but high interfactor correlations violat
