Abstract:
Objective To examine the reliability and validity of the mental disorder predictive scale for servicemen. Methods A test with the mental disorder predictive scale for servicemen was carried out in 1 477 soldiers and officers selected by random cluster sampling, and 120 of them were also tested by Chinese Military Mental Health Scale (CMMHS) at the same time. Statistical software was used to analyze the results and to assess the reliability and validity of the mental disorder predictive scale . Results The Cronbach's α coefficient of the total scale was 0.784, and those of the subscales were 0.705-0.854 (P <0.01). The half reliability of total scale was 0.914, and those of the subscales were 0.754-0.934(P <0.01). The correlation coefficients among factors were 0.512-0.948 (P <0.01), and the correlation coefficients of single factors with total scale score were 0.673-0.961 (P <0.01). Dimensional analysis proved that there were good distinctions between subscales. The exploratory factor analysis showed that the results of this study agreed with the collation of each entry factor of the original scale. There was a higher degree of fitting according to the results of confirmatory factor analysis. The validity of the present scale was effective. Conclusion The reliability and validity of the mental disorder predictive scale for servicemen are satisfactory and meet the standard psychometrics; it can be utilized as an effective tool for prediction of mental disorders among servicemen.
