Subjective Memory Complaints, Objective Memory Performance and Cognitive Training

The aim of this study is to examine if repetitive computerized cognitive training improves working memory in patients who are on sick leave due to complex symptom disorders (chronic pain, chronic fatigue, anxiety, depression and or sleep disorders), and whether effects of cognitive control training transfer to other tasks.

Primary outcomes

  1. Working memory capacity

    Time frame: 7 weeks

    Objective memory performance as assessed by a sample of neuropsychological tests from Cambridge Cognition - Cantab tests (Spatial Working Memory (SWM), One Touch Stockings of Cambridge (OTS), Stop Signal Task (SST)) Including Paced Auditory Serial Addition Test (PASAT).

Secondary outcomes

  1. Subjective memory complaints (SMC)

    Time frame: 7 weeks

    Subjective memory complaints (SMC) are measured by a self-report questionnaire "The Everyday Memory Questionnaire" We estimate prevalence of subjective memory complaints and examine the correspondence between SMC and symptoms of depression, anxiety, sleep disturbances, chronic fatigue and chronic pain.

  2. Transfer to inhibition

    Time frame: 7 weeks

    Transfer to inhibition is demonstrated by significantly reduced Stop Signal Reaction Time on The Stop Signal Task
