The Staff Attitude to Coercion Scale (SACS) - Polish adaptation.

OBJECTIVES

The aim of the study was to prepare the Polish adaptation of the SACS. The scale is a self-assessment tool designed to measure staff attitudes towards direct coercion of psychiatric wards patients.

METHODS

The sample consisted of 120 adults, staff from 7 psychiatric wards. The SACS is a tool created in Norway by Tonje Husum, comprising of 15 items describing psychiatric healthcare professionals attitudes towards direct coercion. The validation procedure incorporated three basic methods to be applied in the reliability analysis - the comparison of double tests with the same method, the analysis of statistical properties of test items as well as analysis of the relation of test items and subscales with the general test result.

RESULTS

After a "think aloud" type pilot study and a language validation, the internal consistency was assessed. The Cronbach's alpha ranged from 0.57 to 0.81 in the subscales, and it was 0.82 for the total score. The best solution obtained in exploratory factor analysis was a three-factor model, almost identical to the original one, confirming the division into three subscales: coercion as offending (critical attitude), as care and security (pragmatic attitude) and as treatment (positive attitude).

CONCLUSIONS

The psychometric characteristics of the Polish adaptation of the SACS are similar to those reported in the original version. The results allow to recommend the method for scientific research. However, further analyses are necessary to assess validity and discriminative power in larger settings.
