How do the authors describe the CURRENT reliability of the Pittsburgh Sleep Quality Index?

How do the authors describe the CURRENT reliability of the Pittsburgh Sleep Quality Index?

  1. They compared the odd and even questions on the test to determine their equivalence.
  2. A team of staff nurses was trained by the primary investigator to ensure that all physiologic measurements were taken using the same methods.
  3. They tested the current group of subjects using two different versions of the same questionnaire (alternate forms reliability).
  4. They computed a Cronbach’s alpha on the questionnaire that was administered to this group of subjects.

 

 

 

 

  1. How do the authors describe the validity of the The Occupational Fatigue Exhaustion Recovery Questionnaire used in this study?
  2. The The Occupational Fatigue Exhaustion Recovery Questionnaire was examined by face, construct, and discriminant validity methods.
  3. The The Occupational Fatigue Exhaustion Recovery Questionnaire was examined by convergence and divergent validity methods.
  4. The questionnaires were reviewed by five experts prior to being used in this study.
  5. The readability levels were identified prior to being used in this study.

 

Were any physiological measurements collected from the subjects for the purpose of this study?

  1. Yes
  2. No

 

  1. Which of the following best describes the data collection process used in this study?

(Select all that apply)

  1. Participants were contacted by phone by nurse researcher.
  2. Participants were given the questionnaires on enrollment in the study
  3. Questionnaires / surveys were mailed to the prospective returned in a self-addressed stamped envelope.
  4. Research assistants consented participants after screening for cognitive deficits.
  5. Questionnaires were distributed through a Web-based platform.

 

  1. Based on the study’s data collection methods, if there were more than one data collector, would an estimation of inter-rater reliability be an important concept for the authors to report on for this study?
  2. Yes, and the authors reported their efforts to achieve inter-rater reliability.
  3. Yes, but the authors do not discuss any efforts to achieve inter-rater reliability.
  4. No, the issue of inter-rater reliability does not apply here.

 

What is the level of significance (alpha level) set at for this study?

  1. .01 or 1%
  2. .05 or 5%
  3. .10 or 10%
  4. An alpha level or level of significance chosen by the authors was not specifically mentioned in the text of the article.

 

Which statements below, as reported by the author, would be considered a limitation of the study? (Select all that apply)

  1. The use of a convenience sample of decreases sample bias.
  2. These study instruments have not been used in other studies on work-related fatigue in ENs.
  3. Results using self-report data may decrease accuracy and validity.
  4. The longitudinal design does not allow for assessment of changes in variables over time.
  5. The hypotheses that work related fatigue has an effect on cognitive function cannot be supported due to lack of data on when the questionnaires were completed.
