The hormone replacement therapy self-efficacy scale



The hormone replacement therapy self-efficacy scale¶This study describes the initial development and psychometric evaluations of an instrument to measure self-efficacy in hormone replacement therapy (HRT) use. The development of the scale was based upon Bandura’s self-efficacy construct. The sample was 116 women who were 50 years old and above and who were current or past users of HRT. Factor analysis was used to develop construct validity and Cronbach’s alpha was used to compute reliabilities. Factor analysis isolated two factors, efficacy beliefs in HRT (EBs-HRT) and outcome expectations in HRT (OEs-HRT). The developed tool contains 14 items, eight items compose the EBs-HRT subscale and six items make-up the OEs-HRT subscale. The two subscales and total instrument were found to have good internal reliabilities. Implications for HRT intervention using the developed tool are discussed.
