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

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)

	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

GEE = generalized estimating equation; SE = standard error; df = degrees of freedom; CI = confidence interval.
GEE analysis was conducted with the percentage of abstinent days as a dependent variable.
^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.
^b Adjusted for adjustment factors in ^a. Regression coefficient refers to a per-point increment in the score for perception of impaired control.
^c Adjusted for adjustment factors in ^a. Regression coefficient refers to a per-point increment in the score for perception of drinking problems.
^d Adjusted for adjustment factors in ^a. Regression coefficient refers to a per-point increment in the total score.
