BACKGROUND: The Hypertension Self-Care Profile Behavior (HTN-SCPB) scale is a self-report instrument with which a patient's self-care behavior can be assessed. However, its psychometric properties for adult patients with hypertension in Vietnam require clarification.

OBJECTIVE: The aim of this study was to translate the HTN-SCPB scale into Vietnamese and to assess its psychometric properties.

METHODS: The study included 220 adult patients with hypertension. To evaluate test-retest reliability, 133 participants were tested twice with a 3-week interval between tests. For construct validity, exploratory factor analysis was used to assess factor structure, and confirmatory factor analysis was used to evaluate the structural model fit of the scale.

RESULTS: Reliability was confirmed by internal consistency (Cronbach α = 0.79) and test-retest reliability (intraclass correlation coefficient, 0.88). The Kaiser-Meyer-Olkin value was 0.75, and Bartlett's test of sphericity was significant (P < .001) and adequate for exploratory factor analysis. A 5-factor structure was obtained, and the factors were named as follows: "advanced self-management skills," "adverse health behaviors," "medication adherence," "diet-related knowledge regarding hypertension," and "information skills." Confirmatory factor analysis revealed that the model fit indices were acceptable (root-mean-square error of approximation, 0.07) or slightly less than the good fit values (comparative fit index, 0.85; incremental fit index, 0.85; goodness-of-fit index, 0.88; adjusted goodness-of-fit index, 0.84; and Tucker-Lewis index, 0.82).

CONCLUSIONS: The Vietnamese HTN-SCPB scale had satisfactory validity and reliability for assessing self-care behaviors in patients with hypertension in Vietnam.
