Abstract
ObjectiveTo develop a self-assessment questionnaire for menstrual abnormalities and test its reliability and validity. To provide an assessment tool for self-identification of abnormal menstruation in young women and to investigate the health seeking situation of abnormal menstruation in the population.MethodsFifteen physicians with clinical experience were invited to participate in the Delphi expert consultations. Medical indications for menstrual abnormalities were constructed and questionnaires were formed based on domestic and international literatureï¼ expert meetings and 2 rounds of Delphi expert consultations. A whole-group sampling was used to select 923 female college students from a medical school in Shanghai for the surveyï¼ and 306 of them were retested. The internal consistencyï¼ retest correlationï¼ researcher-investigator evaluation correlationï¼ and structural and response validity of the questionnaire were examined.ResultsThe questionnaire formed 6 dimensions with 17 indications. The positive coefficients for the two rounds of consulting experts were >90%. The mean authority coefficient was 0.857. The Kendall W coordination coefficient was 0.465 and 0.455ï¼ respectively ï¼P<0.001ï¼. The questionnaire Cronbach's alpha coefficient was 0.622. The retest correlation coefficient was 0.459. The correlation coefficient between the researcher's score and the respondents' self-assessment was 0.562. The five common factors extracted by factor analysis were consistent with the structure of the questionnaireï¼ and the cumulative contribution of variance was 54.4%. Total questionnaire scores were moderately to highly correlated with each dimension score ï¼0.409 to 0.699ï¼. There was low correlation between the dimensions ï¼-0.002 to 0.203ï¼. Girls who had sought medical care had higher scores on the total questionnaireï¼ category Aï¼ category Bï¼ cycle dimensionï¼ menstrual dimensionï¼ and dysmenorrhea/PMS dimension than girls who had not sought medical care ï¼P<0.01ï¼ï¼ and the difference between the two groups in menstrual volume dimension scores was not statistically significant.ConclusionThe self-assessment questionnaire for menstrual abnormalities developed in this study has acceptable reliabilityï¼ good structure validity and response validity. It can provide a self-examination tool and medical consultation guidance for young women with abnormal menstruation.
