After a 1-week washout period, crossover of the groups was performed.Results. The SF-36 mental component scores of the combined treatment group improved relative to the single treatment group (11.09 vs. 10.33,p=0.023). Methadone dosage was reduced in both groups (combined therapy group: 8.58 +/- 4.17/7.76 +/- 4.11 (baseline/posttreatment) vs. single therapy group: 8.36 +/- 4.20/8.30 +/- .28,p=0.001).Conclusion.
