Short- and long-term efficacy of brief cognitive-behavioral therapy for patients with chronic temporomandibular disorder pain: A randomized, controlled trial
Abstract We evaluated the short‐ and long‐term efficacy of a brief cognitive‐behavioral therapy ( CBT ) for chronic temporom and ibular disorder ( TMD ) pain in a r and omized controlled trial . TMD clinic patients were assigned r and omly to four sessions of either CBT ( n = 79 ) or an education/attention control condition ( n = 79 ) . Participants completed outcome ( pain , activity interference , jaw function , and depression ) and process ( pain beliefs , catastrophizing , and coping ) measures before r and omization , and 3 ( post‐treatment ) , 6 , and 12 months later . As compared with the control group , the CBT group showed significantly greater improvement across the follow‐ups on each outcome , belief , and catastrophizing measure ( intent‐to‐treat analyses ) . The CBT group also showed a greater increase in use of relaxation techniques to cope with pain , but not in use of other coping strategies assessed . On the primary outcome measure , activity interference , the proportion of patients who reported no interference at 12 months was nearly three times higher in the CBT group ( 35 % ) than in the control group ( 13 % ) ( P = 0.004 ) . In addition , more CBT than control group patients had clinical ly meaningful improvement in pain intensity ( 50 % versus 29 % showed ≥50 % decrease , P = 0.01 ) , masticatory jaw function ( P < 0.001 ) , and depression ( P = 0.016 ) at 12 months ( intent‐to‐treat analyses ) . The two groups improved equivalently on a measure of TMD knowledge . A brief CBT intervention improves one‐year clinical outcomes of TMD clinic patients and these effects appear to result from specific ingredients of the CBT
