Outcome measures collected at baseline, post-intervention, and 1 month follow-up

Variable	Measures	Description	Reliability/validity
Primary outcomes
CP depression symptoms	CES-D	20-item, Likert-type scale	Established validity, internal consistency, reliability [25, 26]
CP family conflict	Family Caregiver Conflict Scale (FCCS) about Stroke Recovery	15-item, Likert-type scale higher scores/higher conflict	Established content/construct validity in stroke CP; reliability Cronbach’s alpha of .93 [27]
SS upper extremity function	Wolf Motor Function Test (WMFT) Motor Activity Log (MAL)	15-item speed measures;2-item strength; low score/faster speed 30-item questionnaire, Likert-type scale; high score/high quality UE use	Inter-rater reliability r = .97; valid in the stroke population [28]
Process variables
CP/SS autonomy support environment	Family Care Climate Questionnaire FCCQ-CP/FCCQ-SS	14-item, Likert-type scale. Higher scores/higher autonomy support perception	Internal consistency > .70; Construct validity supported- higher FCCQ-SS scores related to SS lower perception of criticism, higher family emotional involvement-higher satisfaction with family support (p ≤ .05) [29]
CP fatigue	Piper Fatigue Scale	22-item scale, Likert-type scale. Higher score/higher fatigue	Strong internal consistency reliability Cronbach’s alpha of .97 and construct validity in stroke carepartners [30, 31]
CP strain	Carer Strain Index -CSI (modified)	13-item questionnaire, binary yes/no; higher score/higher strain	Good reproducibility and validity in stroke carepartners, Cronbach’s alpha of .83 [32–35]
CP well-being related to caregiving	Bakas Caregiving Outcome Scale (BCOS)	15-items; 7-point scale; higher scores/more positive caregiving outcomes	Satisfactory reliability and validity in stroke carepartner, Cronbach’s alpha of .90 [36]
CP family functioning	Family Assessment Device (FAD)	27-items; Likert-type scale. Higher score/unhealthy functioning	Concurrent and predictive validity, internal consistency reliability, sensitivity and specificity demonstrated various samples [37] and used in stroke studies [38, 39]
CP perspective of SS memory and problem behaviors	Memory & Behavior Problems Checklist (MBPC)	19-item scale; Likert-type scale. Higher score/higher frequency	Reliability and validity established in dementia population, and internal consistency reliability coefficient = .73 in stroke [40, 41]
SS quality of life	Stroke Impact Scale (SIS)	59-items, 8 domains function	Test-retest reliability ICC = 0.70 to 0.92; Internal consistency alpha coefficient of 0.83–0.90 [42]
SS UE self-efficacy	Confidence in Hand and Movement Scale (CAHM)	20-item (scale 0–100)UE confidence for functional tasks; high scores/high confidence	Reliable and valid with moderate relationship with WMFT 3–9 months post-stroke [43]
SS upper extremity function	Upper Extremity Fugl-Meyer	33-item, 3-point ordinal scale; higher score/higher function	Established reliability and validity in stroke popul. [44, 45]
CARE-CITE usability
CP experience in CARE-CITE	Exit Interview	Three sections assessing confidence in care, value of participation and aspects of CARE-CITe	Interview guide will be reviewed by content and qualitative experts prior to use.
CP satisfaction with CARE-CITE	Feedback forms at end of CARE-CITE modules	5-items, Likert-type scale; higher scores/higher satisfaction	Interview guide will be reviewed by content and qualitative experts prior to use.
CP confidence in using technology	Modified Computer Self Efficacy Scale (MCSES)	10-item, Likert-type scale. Higher scores/higher self-efficacy	Established reliability and validity [46].
CP experience using CARE-CITE	Post-Study System Usability Questionnaire (PSSUQ)	19-item, Likert-type scale. Lower scores/greater usability of instrument	Established reliability and validity [47]
