Psychometric Evaluation of the Modes of Health Information Acquisition, Sharing, and Use (MHIASU) Questionnaire
ABSTRACT
Background:
Few measures that capture individuals’ health information behavior when managing a chronic illness have been evaluated.
Objective:
To evaluate the psychometric properties of the self-administered Modes of Health Information Acquisition, Sharing, and Use (MHIASU); a 23-item questionnaire that measures how individuals with health risks and/or chronic illness acquire, share, and use health information.
Methods:
African American/Black women with hypertension (N = 320) participated in a prospective, observational study and completed the MHIASU questionnaire online. We conducted a psychometric evaluation of the MHIASU using exploratory factor analysis. The evaluation includes item review, construct validity, and reliability.
Results:
Each item of the MHIASU was retained. Construct validity was established using exploratory factor analysis with principal axis factoring. As anticipated, the instrument was found to have three subscales: acquisition, sharing, and use. Reliability was high for all three subscales, as evidenced by Cronbach’s alpha scores ranging from 0.81-0.93.
Conclusions:
Construct validity and reliability of the online, self-administered MHIASU was demonstrated in a large national cohort of African American/Black women with hypertension. Future studies can use the MHIASU to examine health information behavior in other populations managing health concerns and conditions.
