Table 4 Relationship between percentage of abstinent days during the one-year post-treatment period and post-treatment DRCS scores in GEE analysis (n = 145)

From: The predictive validity of the Drinking-Related Cognitions Scale in alcohol-dependent patients under abstinence-oriented treatment

  Regression coefficient (SE) Wald chi-square df 95% CI P-value
Expectancy and resignation 2.07 (0.58) a 12.68 1 0.93–3.20 < 0.001
Perception of impaired control 1.69 (0.51) b 11.12 1 0.70–2.68 0.001
Perception of drinking problems 2.73 (0.73) c 14.09 1 1.31–4.16 < 0.001
Total 0.97 (0.24) d 16.53 1 0.50–1.44 < 0.001
  1. GEE = generalized estimating equation; SE = standard error; df = degrees of freedom; CI = confidence interval.
  2. GEE analysis was conducted with the percentage of abstinent days as a dependent variable.
  3. a Adjusted for adjustment factors (age, number of admissions to a psychiatry department, history of finger tremor, employment status, educational history, and history of illegal drug usage or abuse). Regression coefficient refers to a per-point increment in the score for expectancy and resignation.
  4. b Adjusted for adjustment factors in a. Regression coefficient refers to a per-point increment in the score for perception of impaired control.
  5. c Adjusted for adjustment factors in a. Regression coefficient refers to a per-point increment in the score for perception of drinking problems.
  6. d Adjusted for adjustment factors in a. Regression coefficient refers to a per-point increment in the total score.
