This study examined the psychometric properties of the Chinese Post-Traumatic Growth Inventory among Hong Kong chronic disease patients. Using a cross-sectional design and multistage stratification sampling, 265 chronic disease patients were recruited from a selection of non-governmental organizations and patient self-help groups across Hong Kong. The Chinese Post-Traumatic Growth Inventory total scale and subscales showed satisfactory internal consistency, reliability and concurrent validity. The factor structure of the Chinese Post-Traumatic Growth Inventory fit well with a higher-order intrapersonal factor (self, spiritual and life orientation) and a first-order interpersonal factor. The Chinese Post-Traumatic Growth Inventory was predictive of hope and positive coping but negatively predictive of anxiety. The five Chinese Post-Traumatic Growth Inventory subscales can help practitioners identify meaningful health outcomes for Chinese chronic disease patients.
