The Caregiver Strain Index is a brief 13-item checklist assessing strain related to care provision across financial, physical, social, and time domains. It is widely used to identify caregivers who may benefit from respite, counseling, and additional support services.
Formula: CSI total = number of strain items endorsed (0-13).

Ask the caregiver to answer yes or no to 13 statements covering seven strain domains: employment difficulties, financial strain, physical burden, disrupted sleep, time demands, behavioral challenges from the care recipient, and the emotional and social impact of caregiving. Each 'yes' scores 1 point.
Sum all endorsed items. Score range is 0-13. A score of 7 or above indicates high caregiver strain (published sensitivity 77%, specificity 82% for caregiver distress). The original validation by Robinson (1983) established this threshold in family carers of hospitalized older adults.
Scores of 7 or above trigger structured support response: social work assessment of available community services, respite care discussion, referral to carer support groups or counseling, safety assessment for both caregiver and care recipient, and follow-up planning within 2-4 weeks.
Discharge Planners & Social Workers
CSI administered to family carers at hospital admission or during discharge planning identifies high-strain carers who may be unable to safely manage the care recipient at home post-discharge. Early identification allows proactive community care arrangement before patient return home.
Geriatric Medicine Teams
Include CSI in routine geriatric outpatient appointments to monitor carer wellbeing longitudinally. Increasing strain scores over successive visits may precede carer crisis and emergency care placement—early detection enables preventive intervention.
Stroke Rehabilitation Teams
Family carers of stroke survivors experience high strain related to physical care demands, role reversal, and behavioral changes. CSI administered at stroke rehabilitation discharge and 3-month follow-up identifies carers requiring additional support during the community adaptation phase.
Palliative Care Community Teams
Carers supporting terminal illness at home carry disproportionate physical and emotional burden. CSI provides a validated brief measure for community palliative nurses to identify carers who are reaching their limit and need urgent respite, social support, or bereavement counseling.
General Practitioners & Practice Nurses
Family carers of patients with multiple chronic conditions, heart failure, COPD, or dementia are a vulnerable population frequently encountered in primary care. Annual CSI screening identifies carers needing targeted health and welfare intervention.
CSI's binary response format is intentionally simple—carers with limited literacy, fatigue, or distress can complete it quickly. This makes it more accessible than Likert-scale instruments like ZBI-12 in acute hospital settings. The trade-off is less granularity about strain severity within positive items.
After calculating the total, review which specific items were endorsed. Employment-related strain may require different interventions than physical burden or sleep disruption. Item-level review guides targeted rather than generic support responses.
CSI scores of 7 or above should include a brief safety assessment: Is the caregiver experiencing thoughts of harming themselves or the care recipient? Are they providing safe medication management? Is there evidence of elder abuse or neglect? These are rare but critical concerns that CSI does not screen for directly.
Repeat CSI 6-8 weeks after initiating caregiver support interventions. A reduction from high to moderate strain range confirms effectiveness. Persistent high scores despite support indicate need for more intensive intervention or care level escalation.
CSI item content was developed in 1983 and reflects caregiving demands of that era. Contemporary carers may have technology, remote work, and digital health tools that affect how strain manifests. Supplement CSI with brief open-ended questions to capture context-specific challenges not covered by the original items.
Never administer CSI with the care recipient present. Carers will underreport strain if the person they care for is in the room. Schedule a brief separate carer assessment—even 5 minutes—where the carer can respond honestly without concern about upsetting the care recipient.
A CSI score of 7 or above is a flag for further assessment—it does not define the nature or cause of strain. Follow high scores with an open-ended conversation: "What feels most difficult about your caregiving situation right now?" This elicits information that determines the most helpful interventions.
Document CSI scores in patient care records alongside care recipient clinical information. Handover teams—community nurses, allied health, day care coordinators—benefit from knowing carer strain level when planning care intensity and support frequency.
CSI is a long-standing caregiver-strain screening tool with broad use across clinical care settings.
Higher CSI totals indicate greater caregiver strain and stronger need for caregiver-focused support.
Use in routine caregiver assessment to identify strain early and guide support planning.
Binary responses may miss nuance of burden severity; consider follow-up qualitative assessment.
