title: Evaluation of the utility of Liebowitz Social Anxiety Scale and Barratt Impulsiveness Scale in the diagnosis of social anxiety, impulsivity and depression.
abstract: BACKGROUND
  Often mental disorders are serious problems concerning psychological well-being. They require comprehensive and specialized psychiatric and psychological help, but there are no public methods of controlling your mental state. The aim of study was the evaluation of the utility of Liebowitz Social Anxiety Scale and Barratt Impulsiveness Scale in the diagnosis of social anxiety, impulsivity and depression.
  
  
  METHODS
  The study included 85 persons. The study group had 34 patients treated in an open ward of the Department of Psychiatry and Psychotherapy of Medical University of Silesia in Katowice. The control group included 51 persons without mental disorders. Three self-rating questionnaires were used: Beck Depression Inventory, Barratt Impulsiveness Scale and Liebowitz Social Anxiety Scale. Statistica v10 Statsoft software was used for statistical analysis.
  
  
  RESULTS
  The analyzed groups had significant differences in terms of Beck Scale (U Mann-Whitney test p=0.000001). Average score in study group: 22.94±12.50; in control group: 7.15±6.44. Groups had significant differences in terms of Liebowitz Scale (U test Mann-Whitney test, p=0.000164). Average score in the study group: 60.41±30.30; in control group: 35.01±23.94. Groups had significant differences in terms of Barratt Scale (t-student test p=0.000601). Average in study group: 66.35±9,49; in control group: 59.54±7.87. Significant positive correlation was observed between the results of Beck Scale and Liebowitz Scale (r=0.64465). Correlation was not observed between the results of the Liebowitz and Barrat (r=0.12091 and Beck and Barrat (r=0.21482).
  
  
  CONCLUSIONS
  The intensity of the Liebowitz Social Anxiety Scale is directly proportional to the severity of depression according to the Beck Depression Inventory. The degree of impulsivity by Barrat Impulsiveness Scale does not correlate with the level of depression according to Beck Depression Inventory. The analyzed scales are relevant in the diagnosis of mental disorders.
