Abstract

Purpose: This study was to develop and validate the scale to predict aggression of psychiatric inpatients. Method:The first phase of the study; 50 staffs(nurse, physician, clinical psychologist) were interviewed to provide narrative data, from which 53 items were developed. Content validity was judged by 15 nurses(who worked more than 5 years) and 2 professionals. This preliminary questionnaire was administered to 350 nurses who worked more than 2 years. Item analysis and factor analysis were carried out to validate violence predicting scale. Cronbach’s was used to test reliability of the scale. For data analysis, SPSS WIN 11.0/PC was used. Result: As a result of the item analysis, 42 items were selected from the total of 53 items and three factors were extracted by factor analysis. Three factors were labeled as ‘Hostile verbal expression’, ‘Latent resistance’, and ‘aggressive behavior’. Three factors were explained by 69.449% out of the total variance. The first factor explained 54.629% and the second factor explained 10.079%. The second factor were not mentioned in other study but important factor for aggression prediction in psychiatric inpatient. And the third factor explained 4.741%. Cronbach’s coefficient of the tool was .9830. Conclusion: The scale is identified to be a tool with a high degree of reliability and validity. Therefore, this scale can be effectively utilized for assessment of aggression for psychiatric inpatient.
