Moniz‐Cook 2008a.

Methods	Randomised controlled trial. Study duration:18 months
Participants	113 care recipients (CR) and their family caregiver (CG). CR had a mean age of 77.2 years; CG had a mean age of 63.2 years and were predominantly female.
Interventions	Community Mental Health Nurses Training Intervention (CMHN) Control (usual practice) Primay aim of intervention: Training CMHNs in systematic psychosocial interventions (PSI) to help family caregivers manage behavioural changes in their relative with dementia. (See Table 2)
Outcomes	The General Health Questionnaire (GHQ) The adapted‐Gilleard Problem Checklist (PC) The Hospital Anxiety and Depression Scale (HADS) The Global Deterioration Scale (GDS) (See Table 3)
Notes	Country of origin: Hull, UK. 4 consecutive weekly in home visits following which CMHN exercised clinical judgment about future contact and attended in service clinical supervision with a Clinical Psychologist (Esme Moniz‐Cook) and senior nurse for the duration of the 18 month study, 2 hours, once a week for the first 6 months and once a fortnight for the following 6 months. Individual sessions were held once a month for the final 5 months.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	'Dyads (i.e. CR and CG) were randomly allocated to either condition'
Allocation concealment (selection bias)	Unclear risk	Randomisation procedure not reported.
Blinding of participants and personnel (performance bias) All outcomes	High risk	Level of blinding of participants and personnel not reported. A protocol was in place. Only two CMHNs adhered to the 4 consecutive family treatment sessions. Despite protocol‐led recommendations no relaxation or anxiety management occurred. Only two CMHNs sustained clinical supervision, noted as 'poor adherence' in the text.
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Researchers conducted baseline measures.
Incomplete outcome data (attrition bias) All outcomes	Low risk	Reasons for withdrawal were reported (1 neighbour disengaged, 18 caregivers disengaged, 3 carers relocated, 3 spouse deceased care provided by a child).
Selective reporting (reporting bias)	Low risk	All outcome results at each time period reported.
Other bias	Low risk	Authors supervised CMHNs.
