Despite its common use in evaluating physical activity (PA) preference, there is a lack of consensus on the optimal attribute and level, and this step often lacks rigorous documentation. This study aimed to identify suitable attributes and levels for a PA program for future application in DCE studies.</span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Methods:</b> This study used a mixed-method approach. Initially, a rapid review was performed using databases and search engines. The findings were then used for a 2-stage semi-structured interview for attribute addition and scoring. Finally, top-scoring attributes were selected, and a small expert panel determined their associated levels.</span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Results:</b> In our rapid review, from 8144 titles according to search strategy, 10 were selected for data extraction. After content analysis and integration of similar attributes, 12 were identified and 4 more were added from interviews. Using the opinions of the expert panel, the top 5 attributes were selected and a total of 22 levels were determined for these 5 attributes. The selected attributes included monthly cost, companions, distance, PA time, and PA type, with total scores of 150, 149, 147, 144, and 123, respectively.</span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Conclusion: </b>Our study identified 5 attributes and 22 corresponding levels as effective tools for measuring PA preferences using a DCE approach.&nbsp; As this is a pioneering study, further comprehensive research is recommended for improved outcomes.</span></span></span></span></span></span></span></span><br> <br> <span style="font-size:11pt"><span style="line-height:normal"><span style="font-family:Calibri,sans-serif"><b><span style="font-size:12.0pt"><span style="font-family:"Times New Roman",serif"></span></span></b></span></span></span> Physical Activity, Exercise, Choice Behavior 899 910 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-8872-1&slc_lang=en&sid=1 Mohammad Veisi mveysi95@gmail.com 200319475328460089663 200319475328460089663 No Department of Health Management and Economics, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran Rajabali Daroudi rdaroudi@yahoo.com 200319475328460089664 200319475328460089664 No Department of Health Management and Economics, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran Ramin Kordi ramin_kordi@tums.ac.ir 200319475328460089665 200319475328460089665 No Sports Medicine Research Centre, Tehran University of Medical Sciences, Tehran, Iran Ali Akbari Sari akbarisari@tums.ac.ir 200319475328460089666 200319475328460089666 Yes Department of Health Management and Economics, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran
