Input: Six studies were included, with a total of 440 participants. The interventions examined were cognitive therapy (CT), behavioural therapy (BT), cognitive behavioural therapy (CBT), behavioural stress management (BSM) and psychoeducation. All forms of psychotherapy except psychoeducation showed a significant improvement in hypochondriacal symptoms compared to waiting list control (SMD (random) [95% CI] = -0.86 [-1.25 to -0.46]). For some therapies, significant improvements were found in the secondary outcomes of general functioning (CBT), resource use (psychoeducation), anxiety (CT, BSM), depression (CT, BSM) and physical symptoms (CBT). These secondary outcome findings were based on smaller numbers of participants and there was significant heterogeneity between studies. Cognitive therapy, behavioural therapy, cognitive behavioural therapy and behavioural stress management are effective in reducing symptoms of hypochondriasis. However, studies included in the review used small numbers of participants and do not allow estimation of effect size, comparison between different types of psychotherapy or whether people are "cured". Most long-term outcome data were uncontrolled. Further studies should make use of validated rating scales, assess treatment acceptability and effect on resource use, and determine the active ingredients and nonspecific factors that are important in psychotherapy for hypochondriasis.
Output:

The objective of this review was to assess whether any form of psychotherapy is effective in the management of people suffering from hypochondriasis. Six studies were included in the review. Analysis of data suggested that, compared to being on a waiting list, forms of cognitive and behaviour therapy, or a non-specific therapy called behavioural stress management all improve the symptoms of hypochondriasis. However, the numbers of people in the studies were small and it was not possible to tell how much of an improvement each therapy made. It is possible that the improvements seen were due to non-specific factors involved in regular contact with a therapist rather than specific properties of these forms of psychotherapy. It was also not possible to make comparisons between the different types of psychotherapy. A study of psychoeducation was not considered to be sufficient evidence that this form of psychotherapy is effective.
