Guidelines for Critiquing Data Quality in Quantitative Studies Total points 40

1. Is there congruence between the research variables as conceptualized (i.e., as discussed in the introduction of the report) and as operationalized (i.e., as described in the method section)? (4 points)

Yes, there is congruence between the research variables in the introduction of the report and the method section. The purpose of the study was to explore the relationship of individual, unit, and hospital variables to workplace bullying in Japan among hospital nurses. The researchers’ used the 23-item revised Negative Acts Questionnaire (NAQ-R) to measure bullying, which was described in the introduction …show more content…
If operational definitions (or scoring procedures) are specified, do they clearly indicate the rules of measurement? How was data collected? (4 points)

The responses of 881 full-time nurses who answered the 23 NAQ-R items were analyzed for the study. The scoring procedures were clearly indicated the rules of measurement. The data was collected using the descriptive statistics that summarize participants’ responses to each item. The researchers also used the coefficient alpha to estimate the internal consistency reliability of the 23-item scale.

3. Does the report offer evidence of the reliability of measures? Does the evidence come from the research sample itself, or is it based on other studies? (4 points)

The report of the study has an evidence of reliability of measures of the 23-item scale. Based on the report, the estimate internal consistency reliability was .94 for the lower bound. The research study is based on the research sample itself and it was not based on other studies.

4. If reliability is reported, which estimation method was used? Was this method appropriate? Is the reliability sufficiently high? (4 …show more content…
If validity information is reported, which validity approach was used? Was this method appropriate? Does the validity of the instrument appear to be adequate? (4 points)

The Five-Factor Model approach was used to support the construct validity of the NAQ-R items. This method is appropriate. However, the validity of the Five-Factor Model was not sufficient to support the correlations among item responses.

7. If there is no reliability or validity information, what conclusion can you reach about the quality of the data in the study? (4 points)

If there was no reliability or validity information, the strength of the study and quality are weak. To increase the strength of their future study, the researchers must examine the relationship of the reliability and validity using the objective assessment of the workplace bullying.

8. If a diagnostic or screening tool was used, is information provided about its sensitivity and specificity, and were these qualities adequate? (4
