The overall objective of our research is to develop and validate a new generic RUM (ModRUM вЂ“ Modular Resource-Use Measure).

A standardised RUM would also enhance the comparability of results, improving the validity of comparisons of cost-effectiveness made across RCTs. ДЄ well-validated, generic RUM would avoid duplication of research and improve the quality of resource-use data captured. Where validation has been undertaken, it is often only criterion validity that is assessed by comparing RUM results to administrative data and/or medical records however, it is usually only a subset of the RUM that can be validated. As new RUMs are often designed or adapted from previous RUMs on a trial-by-trial basis and within the time constraints of an RCT, validation is not commonly undertaken. Validation of an outcome measure is a time-consuming process which involves psychometric testing. This is problematic as it limits the ability to draw valid conclusions from which to inform resource allocation decisions. While validation of outcome measures is common and a wealth of literature exists on outcome measure development, psychometric testing of participant-report resource-use measures (RUMs) is not routinely carried out. Within RCTs, cost-effectiveness estimates are frequently informed by participant-reported resource-use and outcomes. Cognitive interviewing has demonstrated the acceptability and content validity of ModRUM.Д®vidence from randomised controlled trials (RCTs) is often utilised by decision-making bodies when making resource allocation decisions. RUM development requires thorough testing to demonstrate and enhance validity. ConclusionsДЄ generic RUM is needed to increase study comparability. The length, content and layout were acceptable to most participants. Common participant suggestions included highlighting important details and providing additional definition or examples for some terms. Other issues included using incorrect recall periods (5 issues) and overlooking questions leading to missing responses (9 issues). Most issues (21 issues by 2 participants) were due to participants including family healthcare use. Of 71 issues, 28 were in comprehension, 14 in retrieval, 10 in judgement, 18 in response and 1 uncategorised.

Seven participants completed the core module and 13 completed the core module plus depth questions. Interviews were conducted in three rounds, with revisions made iteratively and in response to interview findings. Twenty participants were interviewed between December 2019 and March 2020. Data collection and analysis were performed concurrently and in rounds.

Interview transcripts were analysed qualitatively using techniques of constant comparison, to identify common themes and ideas for improvement. Research team members independently scored transcripts to identify errors in comprehension, recall, judgement and response. Interviews were audio-recorded and transcribed verbatim. The interviewer asked follow-up and probing questions to investigate errors, clarity and acceptability. Participants verbalised their thought processes as they completed ModRUM, which allowed errors (issues with completion) to be identified. MethodsДЄ purposeful sampling strategy with maximum variation was used to recruit patients from primary care to participate in вЂњthink-aloudвЂќ interviews with retrospective probing. ModRUM is a brief, generic RUM with a core module on healthcare use and questions/modules to increase depth and breadth. This paper reports on cognitive interviews with patients to test the content validity and acceptability of a new RUM (ModRUM). Psychometric testing of RUMs is rarely conducted. However, RUMs are typically adapted from existing measures on a study-by-study basis, resulting in a lack of standardisation which limits comparability across studies. Self-report resource-use measures (RUMs) are often used to collect healthcare use data from participants in healthcare studies.
