Table 2 Mean MCMI scores for methadone maintained, protracted abstinence, and non-dependent comparison groups.

From: Character pathology and neuropsychological test performance in remitted opiate dependence

  MM mean (SD) PA mean (SD) Comparison mean (SD) Statistics Paired Comparisons*
MANCOVA     Multivariate Test: Wilk's λ (6, 110) = .754; p < 0.015  
Composite MCMI 385.22 (136.66) 395.68 (123.02) 243.74 (63.96) Univariate F = 5.11, df = 2, p < 0.009 A, B
Cluster A 67.89 (32.27) 71.41 (33.85) 39.52 (18.9) Univariate F = 2.58, df = 2, p = 0.084  
Cluster B 179.39 (63.7) 187.78 (55.64) 116.43 (33.42) Univariate F = 6.19, df = 2, p = 0.004 A, B
Cluster C 137.94 (45.94) 136.50 (40.16) 87.78 (21.75) Univariate F = 4.28, df = 2, p = 0.019 A, B
  1. * Tukey's HSD Pairwise Comparisons: A = p < 0.05 for MM vs. Comparison, B = p < 0.05 for PA vs. Comparison, C = p < 0.05 for MM vs. PA.
  2. MM = Methadone Maintained, PA = Protracted Abstinence.
