Aims
Consumer involvement in the design of study materials can ensure their relevance and sensitivity to the target population, leading to higher enrolment rates. This study aimed to co-design and test study invitation materials that are relevant and acceptable to cancer survivors and their caregivers for a population-based survey aiming to capture their supportive care needs and experiences.
Methods
Fifty-two community members, including survivors and caregivers, participated across 15 group workshops and 20 individual interviews. Sample size was determined through concurrent data collection and analysis. During workshops, participants provided feedback regarding the design, wording and layout of a standard invitation letter typically used in registry-based study recruitment. Principles for designing study invitation materials were then identified through content analysis of workshop transcripts. Using these principles, the research team revised the invitation materials. The acceptability of the revised materials was tested through the interviews.
Results
Based on consumer feedback, study invitation materials (an invitation letter and a flyer) were created. In the interviews, these invitation materials were found to be acceptable to community members. Eleven principles for designing invitation materials were identified from the consumer consultations: (i) communicate empathy and sensitivity; (ii) consider appropriate timing for participation request; (iii) convey credibility and legitimacy; (iv) facilitate reciprocal benefit; (v) include a ‘human element’; (vi) increase accessibility and ease of participation; (vii) optimise readability; (viii) promote inclusivity; (ix) provide reassurance around privacy; (x) encourage participation through a call to action; and (xi) support informed decisions.
Conclusions
Through active and repeated consultation with community members, this study developed study invitation materials that were acceptable and relevant to community members. The principles identified in this study can be used by other researchers to develop invitation materials that are sensitive to the needs and preferences of community members to optimise participation in cancer research.
