Abstract:
Aims and method To determine values for reliable change and clinically significant change for the Leeds Dependence Questionnaire (LDQ) and Social Satisfaction Questionnaire (SSQ). The performance of these two measures with the Clinical Outcomes in Routine Evaluation (CORE-10) as three dimension measures of addiction was then explored. Results The reliable change statistic for both LDQ and SSQ was ⩾4; the cut-offs for clinically significant change were LDQ ⩽10 males, ⩽5 females, and SSQ ⩾16. There was no overlap of 95% CIs for means by gender between 'well-functioning' and pre- and post-treatment populations. Clinical implications These data enable the measurement of clinically significant change using the LDQ and SSQ and add to the evidence for the performance of the LDQ, CORE-10 and SSQ as dimension measures of addiction. The CORE-10 and SSQ can be used as treatment outcome measures for mental health problems other than addiction.
