The aims of the present study were (i) to determine SDD for scoring pain behavior on a 0\u20135 point adjectival scale, and (ii) to explore the relationship between SDD, clinically important difference (CID) and effect size (ES) following treatment of known efficacy, and to compare these parameters of pain behavior with those of VAS\u2010scores of pain intensity [van Grootel RJ, van der Bilt A, van der Glas HW. Long\u2010term reliable change of pain scores in individual myogenous TMD patients. Eur J Pain 2007;11:635\u201343]. SDD was determined using duplicate scores on pain behavior from a pre\u2010treatment diary that was completed by 118 patients with myogenous temporomandibular disorders (TMD). CID was determined as the mean change in score following treatment, and Cohen's ES as the ratio between mean change and SD of baseline values. The SDDs were 2\u20133units (40\u201360% of the scale range) for test\u2013retest intervals of 1\u201313 days. CID was 1.13units (22.6%) and ES was 1.38. The normalized SDD and CID values and ES were similar for VAS\u2010scores of pain intensity, i.e., 38\u201349% (SDD), 24.2% (CID) and 1.09 (ES). Because reliable change (change&gt;SDD) exceeds CID, the responsiveness of scoring of pain variables is low for detecting CID. The finding of ES values that are larger than 0.5 (ES for patients with chronic degenerative diseases [Norman GR, Sloan JA, Wyrwich KW. Interpretation of changes in health\u2010related quality of life. The remarkable universality of half a standard deviation. Med Care 2003;41:582\u201392]) suggests that for myogenous TMD (chronic pain not caused by somatic disease and with a large chance on recovery following treatment), there are higher expectations of what constitutes important change.<\/jats:p>","DOI":"10.1016\/j.ejpain.2008.06.002","type":"journal-article","created":{"date-parts":[[2008,7,28]],"date-time":"2008-07-28T16:50:14Z","timestamp":1217263814000},"page":"506-510","source":"Crossref","is-referenced-by-count":6,"title":["Statistically and clinically important change of pain scores in patients with myogenous temporomandibular disorders"],"prefix":"10.1002","volume":"13","author":[{"given":"Robert J.","family":"van Grootel","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hilbert W.","family":"van der Glas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,1,9]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"271","volume-title":"A textbook of occlusion","author":"Clark C.T.","year":"1988"},{"key":"e_1_2_7_3_1","volume-title":"Statistical power analysis for the behavioural sciences","author":"Cohen J.","year":"1969"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3959(94)90153-8"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/00220345920710091201"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinepi.2005.10.015"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1080\/00016359850136102"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-3959(01)00349-9"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/00220345950740110401"},{"key":"e_1_2_7_10_1","first-page":"256","volume-title":"Temporomandibular joint and masticatory muscle disorders","author":"Greenwood L.F.","year":"1994"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9681(87)90069-5"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1093\/ptj\/77.10.1079"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0895-4356(99)00206-1"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/0197-2456(89)90005-6"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1177\/00220345990780031101"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1097\/00002508-200203000-00006"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1080\/03009740500327727"},{"key":"e_1_2_7_18_1","first-page":"24","article-title":"Diagnostic subgroups of craniomandibular disorders, Part I: self\u2010report data and clinical findings","volume":"9","author":"Lobbezoo\u2010Scholte A.M.","year":"1995","journal-title":"J Orofac Pain"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3959(95)00068-2"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1037\/h0043158"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.MLR.0000062554.74615.4C"},{"key":"e_1_2_7_22_1","volume-title":"Orofacial pain: guidelines for assessment, classification, and management.
