Revision and reliability and validity analysis of systematic family dynamics self-rating scale

The invention relates to revision and reliability and validity analysis of a systematic family dynamics self-rating scale. Whether all entries of an original edition need to be reserved is determined through the entry analysis, in-field multicollinearity diagnosis and exploratory factor analysis method; the character of a revised edition scale is evaluated through exploratory factor analysis, confirmatory factor analysis, reliability analysis and criterion validity analysis; scoring is revised in the mode that it ranges from 5 scores to 1 score from complete conformity to complete inconformity correspondingly, 6 entries are deleted, and 23 entries are reserved; after revision, the Cronbach alpha factor of the family atmosphere is 0.816, the Cronbach alpha factor of individualization is 0.755, the Cronbach alpha factor of the system logic is 0.720 and the Cronbach alpha factor of the sickness idea is 0.653; the fit indexes of a model are ideal through confirmatory factor analysis; criterion validity testing is
