Development of Korean Menstrual Symptom Scale for University Students

PURPOSE: To develop Korean Menstrual Symptom Scale (KMSS) for university students and test its reliability and validity. METHODS: The scale was developed by intensive literature review, development of preliminary items, verification of content validity, development of secondary items, verification of construct validity, and extraction of final items. Thirty-nine items were constructed. Data for validity and reliability testing were collected with a questionnaire survey from 391 university students. Data were analyzed with descriptive statistics, factor analysis, and reliability coefficients (Cronbach's α) with the SPSS program. RESULTS: There were 37 final items which were sorted into six factors: ‘negative affection (8 items)’, ‘change of activity level (7 items)’, ‘physical symptom (9 items)’, ‘mood change (9 items)’, ‘change in concentration level (4 items)’, and ‘body water retention (5 items)’. The cumulative percent of variance was 63.3%. Regarding the reliability of the scale, its Cronbach's α was 0.96. Cronbach's α values for these factors ranged from 0.75 to 0.91. CONCLUSION: The KMSS demonstrated acceptable validity and reliability. Repeated research is needed to measure menstrual symptom experienced by women of variable ages.

Analysis of Reports on Observational Studies Published in the Korean Journal of Women Health Nursing based on the STROBE Guideline

PURPOSE: The purpose of this study was to analyze the quality of reports on observational studies published in the Korean Journal of Women Health Nursing (KJWHN). METHODS: Forty-six studies using cross-sectional designs published in KJWHN from January 2011 to June 2013 were selected for analysis. Selected articles were reviewed and evaluated by three reviewers using the 22 items of the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) statement. As some of 22 items had more than one check point, further broken down, 34 checklist items were used for analysis. RESULTS: Overall, the reviewed studies provided sufficient descriptions for many STROBE items. Seven of the 34 items were found to be not applicable, and 15 of the remaining 27 items (55.5%) were evaluated as 'sufficient' in reporting. Only one study included a flow diagram illustrating participation and this lack of flow diagram was the weakest area of reporting in this review. CONCLUSION: Clearer reporting of cross-sectional studies can be attained by attention to vulnerable areas of reporting, such as including a flow diagram of participants, descriptions of sources of bias and reason for non-participation, and describing limitations of the study. Issues regarding the application of STROBE statement items should be actively discussed in order to aid future revision and clarification of items included in STROBE statement.
