Psychometric Properties of the Verbal and Social Interaction Questionnaire for Psychiatric Outpatient Care (VSI-OP), Staff and Patient Versions.

The aim of this paper is to investigate the psychometric properties of the Verbal and Social Interaction questionnaire for psychiatric outpatient care (VSI-OP) by using a confirmatory factor analysis. A further aim is to present the patient and staff perceptions of the frequency of these interactions in this context. The factor structure of the VSI-OP could be explained by three factors for both the staff and the patient versions. The three factors are: 'Inviting the patient to establish a relationship', 'Showing interest in the patients' feelings, experiences and behaviour' and 'Helping the patients to establish structure and routines in their everyday life'. The two first factors were the most frequently occurring actions according to the staff and the patients.
