Encouraging breast screening practices can assist in early breast cancer detection. Literature has proven that behavior interventions in the form of behavior change health communication using social messaging applications is a viable strategy and potentially effective at motivating breast cancer screening among the public. Such studies are scarce in the South East Asian region, particularly in Malaysia, which is the prime motivation for the current study,Based on this promising prospect, we designed a randomized controlled trial to study the effects of applying persuasive health communication materials to initiate behavior change among a group of Malaysian women. Materials are delivered in the form of a health communication program over a social messaging application to promote breast cancer screening practices, which is either a clinical breast examination, or a mammogram. We hypothesize that Malaysian women who are exposed to such materials that are designed based on behavior science and behavior change principles will be nudged and hence more likely to attend breast cancer screening compared to a control group., conditionsModule conditions: Breast Neoplasm Female, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: PARALLEL, primaryPurpose: SCREENING, maskingInfo masking: DOUBLE, whoMasked: INVESTIGATOR, whoMasked: OUTCOMES_ASSESSOR, enrollmentInfo count: 1180, type: ESTIMATED, armsInterventionsModule interventions name: Standard Health Communication Intervention, interventions name: Behavioural Change Health Communication Intervention, outcomesModule primaryOutcomes measure: Breast cancer screening attendance (either clinical breast examination (CBE) or mammogram)., secondaryOutcomes measure: Health literacy level, secondaryOutcomes measure: Perception based on domains in Health Belief Model, secondaryOutcomes measure: Perceived acceptance and usefulness of health communication program, secondaryOutcomes measure: Reasons behind participants not participating in breast cancer screening., eligibilityModule sex: FEMALE, minimumAge: 40 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: Institute for Clinical Research, National Institutes of Health, Malaysia, city: Shah Alam, state: Selangor, zip: 40170, country: Malaysia, contacts name: Nicholas Yee Liang Hing, MSc, role: CONTACT, email: hingyl@moh.gov.my, geoPoint lat: 3.08507, lon: 101.53281, hasResults: False
