Development and preliminary testing of a questionnaire to measure mobile health information‐seeking behaviour in people with cancer

AIM: The aim of the study was to develop and psychologically test the mobile health information‐seeking behaviour (MHISB) questionnaire in people with cancer. DESIGN: Instrument development. METHODS: The study was conducted in three phases in a southeastern city of China from May 2017 to April 2018. In phase one, an item pool was constructed based on a literature review and semistructured interviews. In phase two, expert evaluation and cognitive interviews were used to evaluate the content validity of the questionnaire. In phase three, a cross‐sectional study was conducted with people with cancer. Cronbach's α was calculated for reliability analysis. Validity evaluation included content validity and construct validity. RESULTS: The developed MHISB questionnaire has four dimensions (information‐seeking frequency, information‐seeking self‐efficacy, health information evaluation and information‐seeking willingness) and 25 items. Psychometric findings were satisfactory and supported the questionnaire's reliability. CONCLUSIONS: The construction process of the MHISB questionnaire was scientific and feasible. The MHISB questionnaire had acceptable validity and reliability, and it requires further improvement in future studies.
