Abstract

AIM: This study was to evaluate the psychometric properties of the Chinese version of the 12-item Perception of Aggression Scale (POAS).

METHOD: It consists of three phases of testing, including (1) translation and back-translation and content validity; (2) semantic equivalence between translated Chinese and original English version; and (3) construct validity, internal consistency and test-retest reliability.

RESULTS: The translated Chinese and back-translated English version showed excellent similarities and agreements between two independent translators. The Chinese version indicated high item- and scale-level content validity indexes (0.86-1.00) and satisfactory semantic equivalence with the original English language version (weighted kappa=0.48-0.90; intraclass correlation coefficient=0.91). Exploratory factor analysis in 249 nursing students resulted in three components (dysfunctional, functional and protective dimensions), explaining 64% of the total variance, with satisfactory internal consistency (Cronbach's alpha=0.76-0.83) and good 2-week test-retest reliability (Pearson's r=0.87). The Chinese version of POAS was found to be a valid and reliable tool to examine nurses' attitudes towards patient aggression.

DISCUSSION: Chinese nurses in this study viewed patient aggression to be an undesirable negative behaviour suggestive of uncontrollability behaviour presented by the patient under their care.
