Furthermore as main outcome variable safety psychopathological symptoms and duration of an intervention cannot meet the demand to indicate subjective suffering and impact relevant to posttraumatic stress syndromes. An instrument used in controlled trials should assess the patients subjective experiences needs to be applicable to more than one intervention in order to compare different coercive measures and has to account for the specific psychiatric context. Methods The primary version of the questionnaire comprised 44 items nine items on restrictions to human rights developed on a clinical basis and 35 items on stressors derived from patients comments during the pilot phase of the study. An exploratory factor analysis EFA using principal axis factoring PAF was carried out. The resulting factors were orthogonally rotated via VARIMAX procedure. Items with factor loadings less than .50 were eliminated. The reliability of the subscales was assessed by calculating Cronbach. Results Data of 102 patients was analysed. The analysis yielded six factors which were entitled Humiliation Physical adverse effects Separation Negative environment Fear and Coercion . These six factors explained of the total variance. Cronbach alpha ranged from .67 to .93 which can be interpreted as a high internal consistency. Convergent and discriminant validity yielded both highly significant results r .79 p .001 resp. r .38 p .001 . Conclusions The Coercion Experience Scale .
