Understanding family dyadic communication in dementia is essential to promote the well-being of family caregivers and persons living with dementia. The Dyadic Communication Observational coding scheme in DEmentia care (DCODE) was developed and tested to assess family dyadic communication in dementia.
The DCODE was developed from a review of literature, expert review, and pretesting. A secondary analysis of the 75 in-home care video observations from 19 family caregiver-care recipient dyads was conducted to test psychometric properties.
The DCODE consists of 43 caregiver items and 41 care recipient items. We observed internal consistency, intra-rater reliability, and inter-rater reliability as adequate. Content validity and convergent validity were moderate. Predictive validity was moderate in predicting caregiver burden. The overall psychometric properties demonstrated a moderate quality of the DCODE.
Findings provided the preliminary psychometric evidence of the DCODE as a promising instrument to assess family dyadic communication in dementia. Future testing for concurrent, divergent, and structural validity of the DCODE is needed.
了解痴呆症患者家庭二元沟通对于促进家庭照料者和痴呆症患者的福祉至关重要。开发并测试了痴呆症护理中的二元沟通观察编码方案（DCODE），以评估痴呆症患者的家庭二元沟通。
DCODE是在文献回顾、专家评审和预测试的基础上开发的。对来自19对家庭照料者-受照料者二元组的75次居家护理视频观察进行了二次分析，以测试其心理测量特性。
DCODE由43个照料者项目和41个受照料者项目组成。我们观察到内部一致性、评分者内信度和评分者间信度都足够。内容效度和收敛效度中等。在预测照料者负担方面，预测效度中等。总体心理测量特性表明DCODE质量中等。
研究结果为DCODE作为评估痴呆症患者家庭二元沟通的有前景工具提供了初步的心理测量证据。未来需要对DCODE的同时效度、区分效度和结构效度进行测试。
