ABSTRACT
Objective To prepare a primary dysmenorrhea self-management behavior scale used for female college students in China.Methods Based on Green health education model,a pool of 40 items was made through literature review as well as semistructured interviews on primary dysmenorrhea in female college sudent.In the following,a primary dysmenorrhea scale for female university students with 20 items was made by considering the advice from five obstetrists and gynecologists and employing a pre-test.Then the primary scale was used for an investigation among 100 female college students with dysmenorrheal and the items were screened by using by item analysis,and a scale with 19 items was decided.The revised scale was finalized by using it among 500 female students with dysmenorrheal in a college in Dalian for a formal investigation,with the reliability and validity tested by factor analysis and correlation analysis.Results The finalized scale was estabhshed containing four dimensions of 19 items.The scale internal consistency Cronbach's α coefficient was 0.91,the index on behaviour,gaining knowledge,treatment compliance and asking for help 0.77,0.88,0.86 and 0.84 respectively.The retest reliability was 0.92 and the index on each dimension was 0.76,0.84,0.83 and 0.77,respectively.The total content validity index of scale content validity index (S-CVI) was 0.93.The content validity index of each dimension,the item cotent validity (I-CVI)was 0.93,0.92,0.92 and 0.94,respectively.By exploratory factor analysis and screen plot,four factors were extracted,with a cumulative contribution rate of 62.90％.The correlation coefficients between the various dimensions were 0.12 to 0.35 and the correlation coefficients between the dimensions and total score were 0.49 to 0.78 (all P ＜0.05).Conclusions Primary dysmenorrhea self-management behavior scales for female college students has a good reliability and validity.It can be used as a tool to evaluate the self management behaviors of female college students in our country.
