Health related quality of life changes in somatising patients after individual versus group cognitive behavioural therapy: a randomized clinical trial.
OBJECTIVE
To assess changes in health related quality of life after a cognitive behavioural program for patients diagnosed with abridged somatization disorder in primary care.


METHODS
A multicentre, randomized, parallel group, controlled trial was designed. 168 patients were recruited from 29 primary health care centres in Spain and were randomly assigned to one of the three study arms: treatment as usual improved with Smith's norms, individual cognitive behavioural treatment, and group cognitive behavioural treatment. Health-related quality of life was assessed using SF-36 Health Survey.


RESULTS
Individual cognitive behavioural treatment achieves greater changes in health related quality of life than group cognitive behavioural therapy and treatment as usual. Improvement in health related quality of life was fully observed at 12 month, and partially at 6 months. The modality of intervention interacts with time in all dimensions except for Physical functioning and Vitality. Patients who received individual cognitive behavioural therapy treatment had better scores in Physical and Mental health summary measures at 12 month follow-up.


CONCLUSIONS
Individual cognitive behavioural treatment is the most effective way to improve health related quality of life in abridged somatization disorder patients, and its effects are sustained over time. Also, regardless of the type of intervention, physical functioning improves compared with treatment as usual.
