Pan 2019.

Methods	Randomised controlled trial
Participants	Family caregivers of patients with dementia (PWD) recruited from community health centres and an 880‐bed tertiary hospital (discharge lists of neurological units) in a city in southeastern China Inclusion criteria 1. 20 years of age or older 2. Serving as primary caregiver for a family member diagnosed with Alzheimer's disease or vascular dementia or with a Mini Mental Status Examination (MMSE) score < 17 3. Living in the target city or its metropolitan area 4. Depressive symptom score ≥ 10 but < 20 5. Able to understand and speak Mandarin Exclusion criteria Individuals who showed signs of suicidal tendencies, history or evidence of a psychotic disorder, or intellectual deficits, or were being treated at a mental health clinic
Interventions	Intervention Nurses were trained in the intervention protocol and in relevant psychosocial skills and were instructed to follow the protocol. A Wechat group (Tencent, Shenzhen, China) allowed nurse interventionists to discuss procedural issues to maintain intervention consistency. The cognitive‐behavioural intervention consisted of 5 monthly 60‐minute, face‐to‐face, individual sessions with a 20‐ to 30‐minute telephone consultation after each session. Face‐to‐face sessions were conducted by nurse interventionists early in the month. Details were flexible and were tailored to the culture of family caregivers of PWD. Telephone consultations were conducted to obtain participant feedback, to reinforce strategies, and to answer questions Control Participants in the control group received 5 monthly, short, general conversations from nurses early in the month at participants' homes, in the hospital units during medical visits, or via telephone contact. The conversation was a 5‐ to 10‐minute casual chat about daily life and health. Nurses responded naturally by showing concern but with no in‐depth instructions. Participants did not receive any additional interventions, with the possible exception of regularly scheduled medical visits
Outcomes	1. Caregiver depression: CES‐D 10 2. Caregiver coping (20‐item simplified coping scale) 3. PWD’s Activities of Daily Living Scale (14‐item) 4. PWD’s Cognitive Function Scale (MMSE)
