Validation of the Indonesian version of Champion's Health Belief Model Scale for breast self-examination.

Abstract

PurposeThe present study aimed to adapt and determine the psychometric properties of the Indonesian version of the Champion’s Health Belief Model Scale (I-CHBMS) of breast self-examination in the measurement of belief toward breast cancer screening.Subjects and methodsA convenience sample of 406 Indonesian women aged 19–60 years was recruited. This study was conducted in Surabaya from December 2016 to January 2017. The I-CHBMS applied a “forward–backward” translation procedure to translate from the English version into Indonesian. Validity of the I-CHBMS was assessed using content, face, and construct validity. Confirmatory factor analysis was used to assess the construct validity. Reliability was measured using Cronbach’s alpha coefficient.ResultsThe result of confirmatory factor analysis indicated 42 items of I-CHBMS with six-factor solution (susceptibility, severity, benefits, barriers, cues to action and self efficacy) were acceptable as a new instrument. Cronbach’s alpha of the subscale ranged from 0.669 to 0.866, indicating a good range of reliability.ConclusionThe finding of the study suggested that I-CHBMS of breast self-examination practice has good psychometric properties and could be an appropriate measure for health beliefs related to breast cancer screening.
