Study characteristics
Methods	RCT
Participants	N = 60 (30F/30M) Typical Alzheimer's disease in accordance with International Working Group‐2 diagnostic criteria All receiving AChEI medication Mean MMSE 16.9 (SD 4.3) Age ‐ no information provided Community residents
Interventions	CST groups based on Roy's adaptation model (RAM) (N = 30) Treatment‐as‐usual controls (N = 30)
Outcomes	Cognition: Standardised MMSE Quality of Life: QoL‐AD Coping and Adaptation Processing Scale (CAPS)
Notes	45 minutes, twice a week for 7 weeks
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Electronic randomisation programme used
Allocation concealment (selection bias)	Unclear risk	No information about allocation concealment and independence of randomisation
Blinding of outcome assessment (detection bias) All outcomes	High risk	"Pre‐test and post‐test data were collected and RAM‐based CST was applied by the same person".
Incomplete outcome data (attrition bias) All outcomes	Low risk	Attrition reported as zero and no cases were excluded from analysis
Selective reporting (reporting bias)	Low risk	All outcome measures mentioned in methods were reported.
Other bias ‐ training and supervision	Unclear risk	Intervention delivered by first author of the paper but little information about receiving training in CST
Other bias ‐ treatment manual	Low risk	Based on the manualised CST programme (Spector 2006)
