Abstract: | The Schwartz Outcomes Scale-10 (SOS-10) is a 10-item scale developed to measure the effectiveness of psychiatric treatments.
Using standard methodology, we translated the scale into Czech and examined the psychometric properties of the Czech version.
207 in-patients admitted to Prague Psychiatric Center were included in the study. All patients completed the SOS at admission
and discharge. The SOS-10 scale was also administered to 170 persons from the general population. Reliability, validity and
sensitivity to treatment change of the Czech SOS-10 were analyzed. The Cronbach’s α coefficient was 0.92. The item-total correlation coefficients varied from 0.56 to 0.82. The SOS-10 correlated well with condition-specific
measures including depression (BDI) and anxiety (BAI) and a global self-rated symptom severity scale (CGI). The SOS-10 also
had significant correlations with the Health, Basic needs, Relationship, and Leisure time domains of the Czech version of
the Subjective Quality of Life Analysis (SQUALA-CZ). The scale discriminated well between patients and controls, with patients
scoring significantly lower on all SOS items. The patient sample’s admission and discharge scores were significantly different,
indicating that the scale is sensitive to treatment changes. We concluded that the Czech SOS-10 is valid with reliability
and factor structure similar to the American language version. |
