Abstract

OBJECTIVES
The present study investigated the reliability and validity of Korean version of schizotypal ambivalence scale, which was developed to measure ambivalence in schizotypy, a latent personality organization that provides the liability for the development of schizophrenia.
METHODS
The psychometric properties of the K-SAS in a sample of 348 normal healthy controls were obtained. Subjects with various range of age and education level of male and female were included in order to investigate the correlation of these demographic variables with the scores of K-SAS.
RESULTS
The internal consistency of the scale was 0.85 and split-half reliability was 0.84. The factor analysis revealed four factors which were labeled as ambivalence on identity, decision, love and outcome, respectively. There were significant main effects for age, gender, and education level. In other words, being older, male, and having more years of education had negative effects on the scale score (p<0.05). These main effects were also valid after the interaction between these demographic factors was excluded through ANCOVA.
CONCLUSION
The Korean version of schizotypal ambivalence scale was a valid tool for measuring ambivalence in schizophrenia. It was found that being older, male, and having more years of education had negative effects on the scale score, and these effects should be considered when using this scale.
