Methods Allocation by method of Taves (minimisation)
Blinded outcome assessment
13 patients and carers (6 treatment, 7 control) lost to follow‐up
6‐month and 1‐year follow‐up
Participants Seattle, WA, USA
140 stroke patients and carers (majority couples) recruited: treatment N = 70; control N = 70; completed final follow‐up: N = 127
Mean age of patient: treatment 63 years; control 62 years
Sex of patient male: treatment 95%; control 94%
Inclusion criteria: all stroke patients on inpatient wards from any referring service, hospitalised primarily for stroke, living with primary caregiver
Exclusion criteria: none stated
Interventions Treatment: 2 classes: (1) lecture and video 'Living with stroke', followed specific outline of information developed by psychiatrists, included basic information about the consequences of stroke; (2) explanation of treatment unique to the family's situation and questions
Focus: carer
Setting: hospital
Administration: occupational therapist (class 1), social worker (class 2). 2 x 1‐hour classes during third week of stroke; second class within 3 working days of the first
Control: routine care

Notes  
Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Patients were randomly assigned to conditions after minimizing the differences for variates known to predict stroke recovery: mood, self‐care ability (Barthel Index), mental status, age, and location of the lesion. The method of Taves[14] was used."
Allocation concealment (selection bias) Unclear risk Method of allocation concealment not reported
Blinding of participants and personnel (performance bias) 
 All outcomes High risk No information reported. However, as no alternative intervention for control groups, blinding of participants not possible
Blinding of outcome assessment (detection bias) 
 All outcomes Unclear risk No report of blinded assessment
Incomplete outcome data (attrition bias) 
 All outcomes Low risk Small numbers lost to follow‐up with similar reasons reported
Selective reporting (reporting bias) Unclear risk Study protocol not available so cannot assess reporting bias
Other bias Unclear risk Imbalance in reported baseline conditions (marital status and number in household) may mean choice of minimisation factors was incomplete
