Psychometric Properties of the Family Caregiver Delirium Knowledge Questionnaire

Abstract

A valid, reliable measure of family caregivers' knowledge about delirium was not located in the literature; such an instrument is essential to assess learning needs and outcomes of education provided. The purpose of the current study was to (a) develop a family Caregiver Delirium Knowledge Questionnaire (CDKQ) based on the Symptom Interpretation Model; and (b) establish validity and reliability of the measure. The 19-item CDKQ was developed and administered to 164 family caregivers for community-dwelling older adults. Descriptive statistics were examined for all variables. Psychometric testing included confirmatory factor analysis, item-to-total correlations, and internal consistency reliability. A three-factor model provided the best fit for the data. The findings support initial validity and reliability of the CDKQ with family caregivers. Although the CDKQ was developed for use with family caregivers, it has potential for use with other caregivers, such as home health aides.

Feasibility and Utility of Online Dementia Care Training for Hospital Staff: The CARES ® Dementia-Friendly Hospital ™ Program

“…Current research in gerontological nursing has tended to focus on delirium in the hospital setting (Bull, Avery, Boaz, & Oswald, 2015; Kolanowski et al, 2011), but there has been less scientific attention paid to individuals with irreversible dementia, such as that caused by Alzheimer’s disease. The current study partially addresses this gap by evaluating the utility and feasibility of online dementia care training for NAs/AHWs in hospital settings, with the long-term aim of improving outcomes for individuals with cognitive impairment, their family caregivers, and NAs/AHWs who often provide the majority of care to these individuals.…”

Psychometric evaluation of the family caregiver ICU delirium knowledge questionnaire

“…After reviewing relevant literature on ICU delirium risk factors and outcomes, one additional item (increased delirium risk in patients who are mechanically ventilated) was added to the CIDKQ [13,15,16]. Similar to the CDKQ [14], the Symptom Interpretation Model (SIM) framework was used [17], which includes three dimensions of delirium knowledge: risks, action and symptoms. A total of 21 multiple choice (yes/no/don't know) items were included in the CIDKQ addressing three dimensions of delirium knowledge: risk factors (items 1-10), actions (items [11][12][13][14][15][16] and symptoms (items [17][18][19][20][21].…”

“…Any, additional items were discussed with the same multidisciplinary team to ensure items were simple, clear and related to ICU delirium knowledge. Due to the sample size, determination of construct validity was not possible using confirmatory factor analysis as was used in the original study of the CDKQ development [14]. Instead, we tested the model from the correlation of the three dimensions of delirium knowledge: risks (items 1-10, score range 0-10), actions (items 11-16, score range 0-6) and symptoms (items 17-21, score range 0-5).…”

“…Many family caregivers do not possess sufficient delirium knowledge to function as partners in the prevention and management of delirium using non-pharmacological strategies. A valid, reliable caregiver delirium knowledge questionnaire (CDKQ) to help nurses evaluate a family caregivers' delirium knowledge exists, but was validated in community-dwelling family caregivers of elective knee and hip patients [14]. There are additional risk factors that predispose a patient to develop delirium in the ICU (e.g., severity of illness, mechanical ventilation, use of benzodiazepines) [13,15] compared to that of a patient in the hospital or community.…”

Preparing Family Caregivers to Recognize Delirium Symptoms in Older Adults After Elective Hip or Knee Arthroplasty

“…Acceptable content and construct validity have been reported; internal consistency reliability for the total instrument has been reported as 0.76. 21 The questionnaire requires approximately 5 to 10 minutes to complete and was administered in pre-and postintervention telephone interviews.…”
