Cognitive Computer Training in Patients With Depression
Study Details
Study Description
Brief Summary
Cognitive impairment plays an important role in functional recovery and leads to long-term sickness absence. Therefore there is a need of a treatment specifically improving cognitive functions. In this pilot study the investigators aim to evaluate the feasibility of using cognitive computer training in patients with unipolar depression to enhance cognitive performance. Further the investigators investigate whether this intervention shortens sick leave.

Detailed Description
This study will evaluate cognitive computer training on patients in remission from depression by measuring the compliance and effect, investigating whether patients returned earlier to work and examine patients' physical and psychological health. This is done by comparing an intervention group and a control group.
Outpatients from psychiatric department Odense in Denmark will be recruited from December 2015 to July 2017.
At enrolment the participants wil be randomized 1:1 to either the intervention group or the control group. After the participants will complete a clinical interview and answer the The Short Form (36) Health Survey (SF-36) questionnaire. The participants' cognitive function and depression severity will be measured at baseline and three months follow-up. At nine months follow-up the participants will receive an email with the SF-36 questionnaire and questions about their education and work status, which they were required to answer.
The intervention is a cognitive computer program, consisting of different computer games. The intervention will start at enrolment and finish at the three months follow-up. The participants in the intervention group will do trainings session lasting 10-20 minutes three times a week. Each participant ends up with a total of 36 training sessions.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Cognitive computer training This is the intervention group receiving cognitive computer training three times a week for three months. |
Other: Cognitive computer training
COGNIFIT is cognitive computer training. Its purpose is to improve cognitive function and is designed to accommodate each individual's cognitive strengths and weaknesses. The cognitive computer training last three months and must be done three times a week, in session lasting 10-20 minutes.

Outcome Measures
Primary Outcome Measures
- Employment status of the participants at nine months follow-up [When the study is completed, approximately 15 months]
Questionnaire about employment status and will be send to the participants via email at nine months follow-up. The questionnaire include questions according to: current working situation; why they are not working; when they started working; do they work at the same workplace; do they have the same work assignments as before they got ill; do whey work the same number of hour as before the got ill.
Secondary Outcome Measures
- The difference in concentration from baseline to 3 months follow-up in the intervention group compared to the control group. [approximately nine months]
Concentration is measured by The Digit Span Test
- The difference in attention from baseline to 3 months follow-up in the intervention group compared to the control group [approximately nine months]
Attention is measured by The Letter Cancellation Test
- The difference in working memory from baseline to 3 months follow-up in the intervention group compared to the control group. [approximately nine months]
Working memory is measured by The Letter Number Sequencing
- The difference in learning from baseline to 3 months follow-up in the intervention group compared to the control group. [approximately nine months]
Learning is measured by the Rey Auditory Verbal Learning Test.
- The difference in executive function from baseline to 3 months follow-up in the intervention group compared to the control group. [approximately nine months]
Executive function is measured by The Verbal Fluency
- The difference in psychomotor speed from baseline to 3 months follow-up in the intervention group compared to the control group. [approximately nine months]
Psychomotor speed is measured by The Trial Making Test (TMT).
- The difference in executive function from baseline to 3 months follow-up in the intervention group compared to the control group. [approximately nine months]
Executive function is measured by The Tower of London
Other Outcome Measures
- Compliance of cognitive computer training [approximately nine months]
The participants were supposed to do 36 sessions of cognitive computer training during three months. The actual completed trainings sessions are available on the website of the cognitive computer training, called COGNIFIT. The compliance is defined as the percentage of actual completed training sessions of the 36 sessions of training.
- The difference in health status from baseline to 9 months follow-up in the intervention group compared to the control group. [approximately 15 months]
The health status is measured by a patient-reported survey called the The Short Form (36) Health Survey (SF-36) questionnaire
- The difference in depression severity from baseline to 3 months follow-up in the intervention group compared to the control group. [approximately nine months]
The depression severity is measured by Hamilton Rating Scale for Depression (17-items)
