| Measure | Time frame |
|---|---|
| The primary outcome of this study is subjective cognitive functioning as measured by the Cognitive Faillure Questionnaire (CFQ) (Broadbent,Cooper, FitzGerald & Parkes, 1982). The CFQ is a self-report questionnaire related to everyday cognitive failure/misstakes related to cognitive functioning. The questionnaire consists of 25 items which are measured using a 5-point scale (0 = never, 4=always). The CFQ has good psychometric properties, include test-retest reliability (Ponds, van Boxtel & Jolles, 2006) and reliability (Bridger, Johnsen& Brasher, 2013). Higher scores are indicative for more subjective congitive symptoms. The CFQ-scores are measured before, during (6 weeks) and after treamtnt to evaluate the course of cognitive functioning during therapy. | — |

|---|---|
| Neuropsychological assesment (NPA) is conducted twice. Firstly, NPA is conducted to provide a framework for the therapy sessions. The second NPA is conducted to evaluate objective cognitive functioning after therapy. This NPA takes approximately 30 minutes and is considered an (minimal) extra effort for patients. NPA is used to assess the different cognitive domains (e.g., memory, attention, executive functioning). Scores will be transformed into classificantion 'no cognitive disorders' (equal to or larger that 20th percentile), 'impaired cognitive functioning' (between 2nd and 20th percentile), and 'cognitive disorder' (smaller than 2nd percentile) based upon the criteria from Lezak, Howiesan, & Loring (2012). The following tests will be conducted: the digit span and symbol substitution from the Wechsler Adult Intelligence Scale (WAIS-IV-NL; Wechsler, 2012) is used to assess working memory and information processing speed, respectively. The Tower test of the DKEFS (Delis et al, 2001) is used to assess planning (Executive functioning), and the rey auditory verbal learning test (15WT; Kalverboer & Deelman, 1986) is used to assess verbal memory processes. The rey osterrieth complex figure test is used to assess visual memory (Osterrieth, 1944) and the d2 is used to assess attention (Brickenkamp, 2002). The psychometric properties of these tests are sufficient and can be found in the manuals (Brickenkamp, 2002;'Delis et al., 2001; Kalverboer & Deelman, 1986; Wechsler, 2012). Note: to control for possible learning effect, during the second NPA the b-version of the RAVLT will be conducted. The learning effect of the other tests are considered minimal | — |
