Sleep Quality and Cognition in Young Adults

April 14, 2021 updated by: mbudak, Istanbul Medipol University Hospital

The Relationship Between Sleep Quality and Cognition in Young Adults

Sleep quality is impaired in young adults due to current conditions. Recent studies emphasize that this situation may also affect the cognitive status of individuals. The aim of this study was to investigate the relationship between sleep quality and cognitive status in young adults. A total of 122 young adults (61 female, 61 male) aged between 18 to 25 and studied at Istanbul Medipol University, Faculty of Health Sciences, were included in the study. Individuals were evaluated with "Pittsburgh Sleep Quality Index (PSQI)" for sleep quality; with "Montreal Cognitive Status Scale (MoCA)" for cognitive status, with "STROOP Test" for selective attention; with "Verbal Fluency Test" for sustained attention; with "WMS-R digit Span Test" for auditory attention

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pittsburgh Sleep Quality Index
Time Frame: 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.
8 March - 26 April 2019
Montreal Cognitive Assessment Test
Time Frame: 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
8 March - 26 April 2019

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
STROOP Test
Time Frame: 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
8 March - 26 April 2019
Verbal Fluency Test
Time Frame: 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.
8 March - 26 April 2019
WMS-R digit Span Test
Time Frame: 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.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
