The findings reported above show that there was a group of people who made significant changes in their level of dependence during the first three months, but did not change much thereafter and a group who did not make changes in dependence during the first three months, but had significant changes in dependence during the subsequent follow-up period to twelve months. For the 50 people who had statistically reliable change scores in dependence between intake and three months, a significant negative correlation was found between such change and change in dependence score between three months and twelve months (Spearman’s rho correlation coefficient: -.5, p<.01, 1-tailed). For the 32 people who had a statistically reliable change score in dependence between three months and twelve months, a significant negative correlation was found between such change and change in dependence scores between intake and three months (Spearman’s rho correlation coefficient -.4, p<.05, 1-tailed).
9.2 Correlates of change in dependence
In Chapter 8 it was reported that, in addition to an overall significant reduction in mean dependence score, changes also occurred in a number of the other domains measured, namely in amounts of the substance used, in frequency of use, in psychological health and in social satisfaction scores. Changes in impaired control (measured as attempts to control, ability to control and perceived control over use) and the use of coping strategies were also investigated. The
