Open Access (OA)

The IJMR is a subscription-only journal but does operate a hybrid gold open access option, to enable those authors with specific OA funding mandates to submit to the journal. Authors will be required to pay a one-off article processing charge (APC) covering the costs of the peer review, copy editing and proofreading process. Once the APC has been paid, authors can post the final, published version of their article on a website, institutional repository or other free public server, without embargo. The APC charge for the IJMR is US$1950/GB£1200.

Articles are eligible for the OA option only after the article has been accepted for publication. We would request that any authors requiring the OA option alert the journal’s Editor as soon as possible after acceptance has been confirmed. For any further queries about this option please contact

Yes-no answers versus check-all in self-administered modes [Download PDF]
Mario Callegaro, Michael H. Murakami, Ziv Tepman and Vani Henderson Vol. 57 No. 2, 2015 pp. 203–223
When writing questions with dichotomous response options, those administering surveys on the web or on paper can choose from a variety of formats, including a check-all-that-apply or a forced-choice format (e.g. yes-no) in self-administered questionnaires. These two formats have been compared and evaluated in many experimental studies. In this paper, we conduct a systematic review and a few meta-analyses of different aspects of the available research that compares these two formats. We find that endorsement levels increase by a factor of 1.42 when questions are posed in a forced-choice rather than check-all format. However, when comparing across a battery of questions, the rank order of endorsement rates remains the same for both formats. While most authors hypothesise that respondents endorse more alternatives presented in a forced-choice (versus check-all-that-apply) format because they process that format at a deeper cognitive level, we introduce the acquiescence bias hypothesis as an alternative and complementary explanation. Further research is required to identify which format elicits answers closer to the ‘true level’ of endorsement, since the few validation studies have proved inconclusive.
