BACKGROUND Generic preference-based measures of health like the EQ-5D and SF-6D ( ® ) are increasingly being used in economic evaluation and outcome assessment .
However , there are concerns as to whether or not these generic measures are appropriate for use in people with mental health problems .
OBJECTIVES The EQ-5D and SF-36 ( ® ) ( including its derivatives the SF-12 ( ® ) and SF-6D ) were assessed using the psychometric criteria of validity and responsiveness using quantitative and qualitative methods .
Another aim was to estimate mapping functions between the EQ-5D and SF-6D and condition-specific measures , where appropriate .
Cost-effectiveness of brief cognitive behaviour therapy versus treatment as usual in recurrent deliberate self-harm: a decision-making approach.
BACKGROUND Deliberate self-harm can be costly , in terms of treatment and subsequent suicide . Any intervention that reduces episodes of self-harm might therefore have a major impact on the costs incurred by service providers and the productivity losses due to illness or premature death . METHOD Four hundred and eighty patients with a history of recurrent deliberate self-harm were r and omized to manual-assisted cognitive behaviour therapy ( MACT ) or treatment as usual .  Economic data were collected from patients at baseline , 6 and 12 months , and these data were complete for 397 patients .  Incremental cost-effectiveness was explored using the primary outcome measure , proportion of patients having a repeat episode of deliberate self-harm , and quality of life . The uncertainty surrounding costs and effects was represented using cost-effectiveness acceptability curves . RESULTS Differences in total cost per patient were statistically significant at 6 months in favour of MACT ( pounds sterling -897 , 95 % CI -1747 to -48 , P=0.04 ) , but these differences did not remain significant at 12 months ( pounds sterling -838 , 95 % CI -2142 to 466 , P=0.21 ) . Nevertheless , exploration of the uncertainty surrounding these estimates suggests there is > 90 % probability that MACT is a more cost-effective strategy for reducing the recurrence of deliberate self-harm in this population over 1 year than treatment as usual . The results for quality of life were not conclusive . CONCLUSION Cost-effectiveness acceptability curves demonstrate that , based on the evidence currently available , to reject MACT on traditional grounds of statistical significance and to continue funding current practice has < 10 % chance of being the correct decision in terms of cost-effectiveness
