Background: Personality and coping have been related to the onset and course of psychotic symptoms. Whether and how these factors contribute to course of illness in terms of mental health care use is unknown. Methods: Psychosis Recent Onset Groningen Survey (PROGR-S) is an ongoing large cohort study of patients with recent onset psychosis . A subsample of 208 first episode non-affective psychosis patients from this database was analysed on personality traits, coping strategies and symptoms in relation to mental health care consumption over two years. Causal inference search algorithms and structural equation modelling were used to generate the best fitting model to explain the associations between these variables. Results: The model suggests that although personality and coping do not directly affect days of hospitalisation, openness to experience and the use of reassuring thoughts do have a direct effect on the amount of ambulatory care. Conclusion: More insight on contribution of specific contributions of personality and coping to prognosis after first episode may stimulate future targeted intervention.
