Introduction Aggressive behavior is frequently associated with acute psychiatric admission. Several studies highlight the increased risk of aggression in certain psychiatric disorders. Objectives The aim of the study was to explore the extent of aggressive behavior, its various manifestations, and its association with gender, age, and diagnosis among patients admitted to an acute psychiatric ward. Methods Patients admitted to our acute psychiatric ward in a three months period were included and the Dynamic Appraisal of Situational Aggression - Inpatient Version (DASA-IV) questionnaire was administered in the first seven days after admission for all patients. Results A total of 290 patients, 153 men and 137 women, with a mean age of 46.9 years (SD=17.5) participated in the study. Men were overrepresented among patients who showed aggressive behavior (p=.008). There was no correlation between age and DASA-IV score (p=.259). 40% of patients (N=116) did not show aggression, while 60% (N=174) experienced some form of aggression. Of those who exhibited some form of aggressive behavior, 94% had only low, 4% had high, and 2% had extremely high levels of aggression. Aggression was most common in patients with intellectual disabilities, dementia, and bipolar disorder. Conclusions According to our findings the majority of the acutely admitted psychiatric patients shows no or only low level of aggression. There were also differences in the forms and extent of aggressive behavior between the diagnostic groups. Risk assessment is important because it provides an opportunity for early detection and prevention, and the development of personalized treatment plans. Disclosure No significant relationships.

Introduction Previous research confirmed high rates (20-89%) of non-adherence to medication among psychotic and bipolar patients. Results suggests that positive attitude to treatment has the highest influence on patients’ adherence and significant differences between treatment related attitudes and treatment adherence of psychotic and bipolar patients were found. Objectives The aims were to compare treatment related attitudes and treatment adherence between psychotic (schizophrenia spectrum) and bipolar patients; to evaluate the relationship between treatment related attitudes, illness perceptions and health locus of control in psychotic and bipolar populations. Methods Treatment attitude was evaluated with the Drug Attitude Scale (DAI). Treatment adherence was rated by doctors on Clinical Global Impression (CGI) Scale. Illness perceptions were evaluated with the Illness Perception Questionnaire for Schizophrenia (IPQS) and health locus of control with the Multidimensional of Health Locus of Control Scale –Form C (MHLC) at the end of inpatient care. Results Number of participants was 51. Data indicated more positive treatment attitude in bipolar patients than in psychotic patients. MHLC scores indicated significant role in symptoms control for chance (p=0,042) and „powerful” persons (p=0,011) in psychotic patients. IPQS scores indicated that bipolar patients rather have perceptions about treatment influencing symptoms than psychotic patients. Treatment related attitudes were strongly influenced by perceptions about controllability of symptoms by treatment. Conclusions Bipolar patients had more positive treatment attitude and perceptions about effectiveness of treatment on symptoms. This illness perception about controllability of symptoms by treatment was the strongest determinant of positive treatment attitude in this study. Disclosure No significant relationships.
