Validation of the Chinese version of perception of care in an acute psychiatric ward in Hong Kong

Introduction: This study aimed to validate and culturally adapt the Perception of Care (PoC) for patients receiving acute psychiatric inpatient services in Hong Kong. Methods: The PoC was translated and culturally adapted into a written Chinese version (C-PoC). Subjects completed C-PoC, Chinese version of Admission Experience Survey (C-AES) and World Health Organization Quality of Life Measure (WHOQOL-BREF). They were then rated by assessors with Brief Psychiatric Rating Scale (BPRS), Hamilton Rating Scale for Depression, Hamilton Rating Scale for Anxiety and Extrapyramidal Symptom Rating Scale. Explorative factor analysis and correlation between C-PoC, WHOQOL-BREF and C-AES served as the theoretical basis of construct validity. Multivariate analysis was used to identify predictors of satisfaction. Results: The C-PoC has a four-factor structure that resembles the original scale with demonstrating satisfactory construct validity and test-re-test reliability. Psychiatric symptom ratings did not predict any satisfaction ratings. Extrapyramidal symptoms predicted poorer satisfaction. Younger patients with affective diagnoses had better satisfaction. Discussion: The C-PoC is a psychometrically sound translation of the original scale. The current study paves the way for further studies among Chinese-speaking communities on the determinants and implications of patients' satisfaction by offering a psychometrically sound and yet concise instrument.
