A Study in Reliability and Validity for Lerner Defense Scale LDS in Rorschach Test

The Research Objective Rorschach Lerner defense mechanism Scale LDS normal subjects and schizophrenic patients , the defense mechanism of neurotic patients , collect information of reliability and validity of the scale in the Chinese population . Clinical practice in the diagnosis of mental illness , the classification and evaluation of the efficacy of the new method . Research methods to select the normal group fine grouping , nerve group were 30 people , Rorschach administered . Retest interval of two weeks of the normal group . Results Lerner defense mechanism scale LDS excellent scoring consistency reliability (kappa coefficient greater than 0.74 ) ; Lerner defense mechanism scale LDS good group of 30 normal adult two weeks after the retest results the test-retest reliability , five defense mechanisms retest correlation coefficients ( 0.72-1.00 ) ; Lerner defense mechanism scale LDS is part of the defense mechanism can effectively distinguish between normal subjects and in different psychiatric disorders . Research conclusions Lerner defense mechanism scale LDS have good reliability , validity , and defense mechanisms of the different populations plexus in the small-scale study of the small sample size , based on these features can be used as aids in clinical diagnosis .
