Caregiver activities are distinct from outcomes because they relate to the tasks that caregivers perform (caregiving input).
Evidence of content validity, based on patient (or caregiver) input is one of the key elements required by FDA guidance.
Taken together, the results of the previous research, supplemental literature review, and caregiver input strongly supported the development of a questionnaire specifically designed to measure behaviors directly observable by caregivers of individuals with juvenile MLD.
Evidence of content validity, based on patient (or caregiver) input through concept elicitation interviews and cognitive debriefing interviews, is one of the key components of the FDA's review of clinical outcome assessment (COA) tools.
Qualitative research, including a review of the literature and direct expert and caregiver input, culminated in a 19-item, developmental version of the GRCD with 9 overnight questions and 10 daytime questions specific to symptoms that can be directly observed by the caregiver of a child with RSV infection.
The GRCD is designed to be self-administered by the caregiver to gather direct caregiver input, completed twice daily at two separate times with recall periods of overnight symptoms ("in the morning after your child has woken up for the day") and daytime symptoms ("since your child awoke this morning until you put your child to bed") in order to capture diurnal variations in symptoms.
Secondary outcome measures included the Mini-Mental State Examination, the Clinician's Interview Based Impression of Change with caregiver input, the noncognitive subscale of the ADAS, the Neuropsychiatric Inventory, and the Interview for Deterioration in Daily life in Dementia.
Secondary outcome measures included the MMSE, [26] the Clinician's Interview Based Impression of Change with caregiver input (CIBIC+), [28] the noncognitive subscale of the ADAS (ADAS-noncog), [27] the Neuropsychiatric Inventory (NPI), [29], [30] including the NPI caregiver distress scale (NPI-D), [31] and the Interview for Deterioration in Daily life in Dementia (IDDD).
Item development was an iterative process based on a literature review and caregiver input.
Psychiatrists made antipsychotic treatment decisions without patient or caregiver input during 40 of 60 (67%) conversations.
