The scale has been used in several studies, but its psychometric properties have been insufficiently investigated and population\u2010based data are not available.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>The objective of this article is to establish the factor structure and discriminant and convergent validity of the GSRS\u2010IBS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The study was based on a Swedish population sample (the Popcol study), of which 1158 randomly selected participants provided data on the GSRS\u2010IBS. We used confirmatory factor analysis (CFA) and compared total and subscales scores in different groups, including IBS diagnostic status, treatment\u2010seeking behavior, and predominant bowel habits. The GSRS\u2010IBS scores were also correlated with quality of life indexes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The sample included 164 participants with a confirmed Rome III IBS diagnosis and 994 participants without the disease. The CFA confirmed the subscales with one exception, in which the incomplete bowel\u2010emptying item belonged to the constipation subscale rather than the diarrhea subscale. The GSRS\u2010IBS total score and subscales were associated with diagnostic status, treatment\u2010seeking behavior, and quality of life dimensions. The relevant subscales scores also differed between the diarrhea\u2010 and constipation\u2010predominant subtypes of IBS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The GSRS\u2010IBS total score and subscales have high discriminant and convergent validity. The CFA confirmed the overall validity of the subscales but suggest that a sense of incomplete emptying belongs to the constipation rather than the diarrhea symptom cluster. We conclude that the GSRS\u2010IBS is an excellent measure of IBS symptom severity in the general population.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/2050640619900577","type":"journal-article","created":{"date-parts":[[2020,1,15]],"date-time":"2020-01-15T02:35:45Z","timestamp":1579055745000},"page":"284-292","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":45,"title":["Discriminant and convergent validity of the GSRS\u2010IBS symptom severity measure for irritable bowel syndrome: A population study"],"prefix":"10.1002","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8086-1668","authenticated-orcid":false,"given":"Brj\u00e1nn","family":"Lj\u00f3tsson","sequence":"first","affiliation":[{"name":"Department of Clinical Neuroscience Division of Psychology Karolinska Institutet Stockholm Sweden"},{"name":"Centre for Psychiatry Research Department of Clinical Neuroscience Karolinska Institutet Stockholm Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0565-4938","authenticated-orcid":false,"given":"Michael","family":"Jones","sequence":"additional","affiliation":[{"name":"Department of Psychology Macquarie University North Ryde NSW Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicholas J","family":"Talley","sequence":"additional","affiliation":[{"name":"Faculty of Health and Medicine University of Newcastle Newcastle NSW Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lars","family":"Kjellstr\u00f6m","sequence":"additional","affiliation":[{"name":"City Gastro Department Stockholm Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lars","family":"Agr\u00e9us","sequence":"additional","affiliation":[{"name":"Division of Family Medicine and Primary Care Department of Neurobiology Care Sciences and Society Karolinska Institutet Stockholm Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0203-7977","authenticated-orcid":false,"given":"Anna","family":"Andreasson","sequence":"additional","affiliation":[{"name":"Department of Psychology Macquarie University North Ryde NSW Australia"},{"name":"Stress Research Institute Stockholm University Stockholm Sweden"},{"name":"Division of Clinical Medicine Department of Medicine Solna Karolinska Institutet Stockholm Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,4]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2016.02.031"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1053\/gast.2000.16484"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/ajg.2014.148"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1080\/00365520310004209"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2007.07.024"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/ajg.2011.340"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/ajg.2011.139"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.brat.2009.05.002"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1037\/a0033439"},{"key":"e_1_2_11_11_1","doi-asserted-by":"crossref","first-page":"254","DOI":"10.1037\/ccp0000273","article-title":"How does exposure therapy work?
