Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Change in working memory capacity from pre-test to immediate post-test will be the primary study outcome. Working memory capacity will be assessed with the Span board task (Klingberg 2005). This task is commonly used in research on the effects of cognitive training on working memory capacity. | — |
Secondary
| Measure | Time frame |
|---|---|
| As secundary outcomes we will assess changes (differences between pre-test, first and second post tests) in other aspects of working memory, craving, mood, and delay discounting (preference for small, immediate rewards over large, long-term rewards) and changes (differences between Routine Outcome Assessment when entering the detix clinic and follow-up assessment) in substance use. Other aspects of working memory capacity will be assessed by the following validated computer tasks: Reading Span Task (Daneman, & Carpenter, 1980; Unsworh, Brewer & Spillers, 2009) Drug Stroop task (Carpenter, Schreiber, Church, & McDowell, 2006; Waters, Marhe, Franken, 2012). Substance use, craving and mood will be measured with scores on questionnaires: Substance use questionnaire (including lifetime, 6-month and 30-day frequency measures, Alcohol Use Disorder Identification Test (AUDIT), Cannabis Use Disorder Identification Test (CUDIT), number of non-using days) OCDS (craving for substance use) (de Wildt, 2010; Hendriks, 2012) BDI-II-NL (depression) (Van der Does, 2002) STAI (state anxiety) (Van der Ploeg, 1980) Delay discounting will be measured with the delay discounting task (Robles, Huang, Simpson & McMillan, 2011). | — |
