The Sense of Competence in Dementia Care Staff Scale in Chinese(SCIDS-C): Adapatation and Validation Amongst Chinese Dememtia Care Staff in Nursing Homes


 Background: Nursing teams experience a high level of stress and caregiving burden when providing care for older residents with dementia. Competence of nursing staff in dementia care is not only essential to improve quality of care for older residents with dementia in nursing homes, but also to improve their own quality of work life. Appropriately assessing their level of competence in dementia care is the first step to develop precision interventions to improve quality dementia care. The Sense of Competence in Dementia Care Staff scale (SCIDS) is a user-friendly tool with satisfactory reliability and validity. Although China has the largest population of persons with dementia, there is no validated tools available to accurately assess formal caregivers’ competence in demenetia care in long-term care settings. Thus, we decided to adapt SCIDS into a Chinese version (SCIDS-C) and validate its use in China’s socio-cultural context to assess nursing staff’s capability and competence in dementia care in nursing homes. Aims: We aimed to adapt and psychometrically test amongst frontline nursing staff in long-term care settings in China.Methods: This two-phase psychometric research employed a correlational design with repeated measures. In phase one, we adapted and tailored the original scale by taking into account the cultural and social context in nursing homes in China. The scale’s adaptation consists of translation and semantic equivalence. In phase two, we tested the validity and reliability of the scale. Internal consistency and stability were used to examine the reliability of the scale. Construct validity was tested using exploratory factor analysis (EFA), including principal component analysis and maximum variance rotation method. We included 174 nursing staff from six nursing homes between September and December in 2020.Results: The SCIDS-C has two sub-scales and 17 items, including the Relationship-Centered Care (RCC) and Professional Care (PC) subscales. The item-total correlation coefficient ranges from0.41 to 0.69 (P<0.001), showing that all items were compatible by the positive correlation. The Cronbach’s alpha of the scale was 0.88, showing a good internal consistency. Test-retest reliability was 0.82. Exploratory factor analysis (EFA) extracted 2 common factors in each sub-scale cumulative variance contribution rate was 56.71% and 53.92%, respectively. The named four factors are the same as the Sense of Competence in Dementia Care Staff (SCIDS) scale in English, i.e. Building Relationships, Sustaining Personhood, Professionalism and Care Challenges.Conclusion The SCIDS-C has shown good reliability and validity. It can be used as an appropriate tool to evaluate the competence of nursing care staff of providing dementia care for residents in nursing homes.
