@entity1 @entity308 @entity146 @entity5562 @entity148 @entity74 @entity1296
BACKGROUND: About 30-50% of @entity74 are organically not sufficiently explained or related to a @entity146 . Of @entity1 with @entity74 , 80% are severely impaired by @entity1296 in their daily and working lives; nevertheless, they are often not diagnosed or treated adequately. OBJECTIVES: This review aims to give a systematic overview of psychotherapeutic approaches and their efficacy regarding the treatment of @entity1296 that is medically not sufficiently explained or related to a @entity146 . METHODS: A systematic literature search was conducted in Medline, PSYNDEX and PsycINFO. Included in this systematic review were (randomised) controlled trials ((R)CTs) concerning psychotherapy in @entity1 with @entity1296 , medically not sufficiently explained or associated with a @entity146 . If possible, Hedges' g was used to express the @entity5562 ( @entity5562 ) of the treatment. Heterogeneity was assessed using the Q statistic. In addition, the quality of the studies was rated. RESULTS: Three (R)CTs were included. All studies used cognitive-behavioural treatment methods in combination with relaxation techniques or vestibular rehabilitation. All studies suggested that psychotherapy may provide improvement. The mean @entity5562 in the treatment groups was 0.46 (95% CI 0.05 to 0.88) for @entity1296 related outcome, 0.10 (-0.44 to 0.64) for @entity148 and 0.17 (-0.24 to 0.58) for @entity308 whereas in the control groups the mean @entity1296 related @entity5562 was -0.04 (-0.44 to 0.37), @entity148 related @entity5562 was -0.03 (-0.43 to 0.38) and @entity308 related @entity5562 was -0.02 (-0.42 to 0.38). The quality of the studies was average. Sample sizes were small, however, and there was a lack of long term studies. CONCLUSION: This systematic review provides some preliminary evidence that psychotherapy may be effective in @entity1 with @entity1296 that is medically not sufficiently explained or due to a @entity146 . The results should be replicated in larger samples and follow-up RCTs.
