| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Pittsburgh Sleep Quality Index | 8 March - 26 April 2019 | Pittsburgh Sleep Quality Index evaluates sleep quality and impairment in the last one month. 19 of the 24 PSQIquestions included were self-report questions. The scale has 18 questions and 7 components: Subjective Sleep Quality "," Sleep Latency "," Sleep Duration ", "Sleep Efficiency", "Sleep Disturbance", "Sleep Medication" and Daytime Dysfunction". The total score ranges from 0-21. A total score greater than 5 indicates poor sleep quality. | ClinicalTrials.gov |
| Primary | Montreal Cognitive Assessment Test | 8 March - 26 April 2019 | Montreal Cognitive Assessment Test (MoCA) examines cognitive abilities such as visual / executive function, naming, episodic memory, attention, language, abstract thinking, and orientation. The original cut-off score of the MoCA test is 26. The cut-off score of 21 was adopted in Turkey. MoCA takes about 10 minutes to apply, but shortened versions have been created to shorten the administration time | ClinicalTrials.gov |
| Secondary | STROOP Test | 8 March - 26 April 2019 | The Stroop Test reflects selective attention, reading and color rendering processes. It is a critical experimental task, often used in the study of automatic and parallel processing models with the speed of information processing. Because of these features, the test is used not only in the evaluation of the cognitive processes of healthy individuals, but also in the evaluation of many psychiatric and neurological disorders | ClinicalTrials.gov |
| Secondary | Verbal Fluency Test | 8 March - 26 April 2019 | Verbal Fluency Test evaluates the tasks performed with frontal and temporal lobe activation. The purpose of this test is to evaluate the mental recall of words starting with the given letter or in the desired category within the prescribed time. | ClinicalTrials.gov |
| Secondary | WMS-R digit Span Test | 8 March - 26 April 2019 | Digit Span Test is the eighth subtest in the Wechsler Memory Scale Developed Form, and evaluates the simple and complex attention of individuals. This sub-test consists of two sub-sections, and a series of increasingly long numbers are read to the person. Both subtests are related to auditory attention and short-term memory. Two separate trials are made for each length sequence. | ClinicalTrials.gov |
