Evaluating the psychometric properties of the Persian version of the Healthy Lifestyle Instrument for Breast Cancer Survivors (HLI-BCS)

BACKGROUND: Precise examination of breast cancer survivors’ lifestyles can lead to improved planning and implementation of care and counseling interventions to increase their survival rate and improve their quality of life. Therefore, a valid and reliable instrument needs to be developed. Therefore, the present study aimed to determine the psychometric properties of the Persian version of the Healthy Lifestyle Instrument for Breast Cancer Survivors (HLI-BCS). METHODS: This methodological study was conducted on 420 Iranian breast cancer survivors between May and November 2022. Participants were selected using convenience sampling. The face, content, construct validity, convergent, and reliability of the Persian version of the HLI-BCS were assessed. RESULTS: After assessing face, content, and construct validity, the Persian version of the HLI-BCS with five factors and 20 items was provided. The total Cronbach’s alpha and intra-class correlation coefficient (ICC) were calculated as 0.86 and 0.79, respectively, which were at acceptable levels. A healthy lifestyle in breast cancer survivors was observed to have strong and significant relationships with quality of life in general (p < 0.001, r = 0.832), physical health (r = 0.786), and mental health (r = 0.809). CONCLUSION: The Persian version of the HLI-BCS has favorable properties, is consistent with the conditions of breast cancer survivors, and is valid and reliable. This version of the scale can provide adequate and precise information on the lifestyles of these patients.
