Translating scientific research

In a sample of 1552 subjects from Portugal, Spain and Brazil, self-reported sleep quality and mental health indicators were assessed through the Pittsburgh Sleep Quality Index and the Depression, Anxiety and Stress Scale-21, respectively. A multivariate linear regression model was used to test the research hypotheses.

The Pittsburgh Sleep Quality Index uses a variety of different items to assess sleep quality and disturbances over a one month period. There are 19 items used to generate a score that ranges from 0-21, the higher the score the worse the sleep quality. In addition to the Depression, Anxiety and stress scale-21, this index was used in a sample on 1552 subjects where they were able to determine the effects that quality of sleep has on mental health.

sleep knowledge has evolved greatly in the last 30 years. The fact that the rats died after been deprived of sleep alerted the scientific community to the importance of understanding sleep and its effects. By 2014, the International Classification of Sleep Disorders (ICSD), had already listed more than 70 sleep-related disorders

The importance of sleep and its effects on mental health is a subject that has become increasingly popular over the past several years. The need for studies like this one has become more apparent and easier to execute due to the increase in knowledge and the resources available such as the International Classification of Sleep Disorders.

This adjusted model explained 10.1%, 12.3% and 13.1% of the variability of Depression, Anxiety and Stress, respectively, suggesting multiple sources of variance.

There were many variables found within the study that effected the score a subject would receive on the scale they were being tested on. Although this study did prove that there is an effect that quality of sleep has on mental health, it also revealed that there are many sources of variance when it comes to testing this subject.

The impact that sleep quality has in mental health on a non-clinical population was analyzed through three different hypotheses (H1 to H3) which were all validated. Consequently, our results demonstrated that sleep quality predicts mental health in these samples

There is certainly a correlation between sleep quality and mental health and there are many ways to track and test this correlation. Each hypothesis tested during this study further proved how sleep quality can predict one’s mental health.

Investigating not only the quality of sleep, but also the quantity of sleep a person gets and how that could potentially affect mental health would be a viable choice for future research as well as help broaden your knowledge of the subject.

It’s difficult to understand the direct effects that quality of sleep has on mental health as there are so many factors that come into play. I now understand the Pittsburgh Sleep Quality Index and the Depression, Anxiety and Stress Scale-21 which helps with understanding the findings of this study. However, there were lots of variables within the findings that made it difficult to understand the direct effects of study.
