Preliminary study of alcohol problem severity and response to brief intervention

Table 2 Motivation to change ruler scores by intervention condition and timepoint

Variable Mean (standard deviation)	Total sample (N = 51)	Brief intervention group (n = 27)	Control group (n = 24)	Sign. (p-value)
Pre-intervention^a
Importance ruler	4.8 (2.6)	4.4 (2.5)	5.3 (2.8)	0.216
Confidence ruler	5.9 (2.6)	5.6 (2.8)	6.1 (2.5)	0.509
Readiness ruler	3.5 (2.0)	3.3 (2.0)	3.8 (2.1)	0.321
Post-intervention^b
Importance ruler	5.5 (2.3)	6.0 (2.2)	5.0 (2.4)	0.001*
Confidence ruler	6.8 (2.4)	7.1 (2.4)	6.5 (2.5)	0.169
Readiness ruler	4.8 (2.3)	4.8 (2.4)	4.8 (2.3)	0.561

Motivation to change ruler scores can range from 1 to 10 points
^aIndependent samples t-test assessed pre-intervention motivation to change differences between conditions
^bGeneralized linear models assessed post-intervention motivation to change differences by condition, covarying for pre-intervention scores
*Indicates significance at the p < 0.05 level
