[Polish version of the Groningen Social Disabilities Schedule II (GSDS II)--assessment of validity].

INTRODUCTION: Precise and adequate assessment of social functioning and disability is a subject of major interest and concern of the researchers. Until now, no instrument with confirmed psychometric properties was established as a supportive measure of disability in the framework of the rehabilitation process with the participation of the National Insurance Agency. A potentially useful instrument for this purpose is the Groningen Social Disabilities Schedule II (GSDSII). AIM: Aim of the study was the evaluation of usefulness of the Polish version of GSDSII as a social disabilities measure in the population of psychiatric inpatients. METHOD: 130 persons with a broad range of diagnoses (schizophrenia, mood disorders, anxiety disorders) were interviewed. For estimation of convergent validity, the following reference tools were selected: Global Assessment of Functioning (GAF), Social Assessment of Functioning scale (SOFAS), Global Assessment of Relational Functioning (GARF), World Health Organization Disability Assessment Schedule II (WHO-DASII). For criterion validity the Brief Psychiatric Rating Scale (BPRS) 24-item version was applied. RESULTS. The sufficient and good validity indices were obtained for concurrent validity of GSDSII. There was also a significant interrelation between psychopathology assessed with BPRS and disability measured by GSDSII. CONCLUSIONS: Results allow for the supplication of the GSDSII in the research on psychosocial disability in Poland.
