The Caregiver Burden Questionnaire for Heart Failure (CBQ-HF): face and content validity.

ABSTRACT: BACKGROUND: A new caregiver burden questionnaire for heart failure (CBQ-HF v1.0) was developed based on previously conducted qualitative interviews with HF caregivers and with input from HF clinical experts. Version 1.0 of the CBQ-HF included 41 items measuring the burden associated with caregiving in the following domains: physical, emotional/psychological, social, and impact on caregiver's life. Following initial development, the next stage was to evaluate caregivers' understanding of the questionnaire items and their conceptual relevance. METHODS: To evaluate the face and content validity of the new questionnaire, cognitive interviews were conducted with caregivers of heart failure patients. The cognitive interviews included a "think aloud" exercise as the patient completed the CBQ-HF, followed by more specific probing questions to better understand caregivers' understanding, interpretation and the relevance of the instructions, items, response scales and recall period. RESULTS: Eighteen caregivers of heart failure patients were recruited. The mean age of the caregivers was 50 years (SD?=?10.2). Eighty-three percent of caregivers were female and most commonly the patient was either a spouse (44%) or a parent (28%). Among the patients 55% were NYHA Class 2 and 45% were NYHA Class 3 or 4. The caregiver cognitive interviews demonstrated that the CBQ-HF was well understood, relevant and consistently interpreted. From the initial 41 item questionnaire, fifteen items were deleted due to conceptual overlap and/or item redundancy. The final 26-item CBQ-HF (v3.0) uses a 5-point Likert severity scale, assessing 4 domains of physical, emotional/psychological, social and lifestyle burdens using a 4-week recall period. CONCLUSIONS: The CBQ-HF (v3.0) is a comprehensive and relevant measure of subjective caregiver burden with strong content validity. This study has established that the CBQ-HF (v3.0) has strong face and content validity and should be valuable as an outcomes measure to help understand and monitor the relationship between patient heart failure severity and caregiver burden. A Translatability AssessmentSM of the measure has since been performed confirming the cultural appropriateness of the measure and psychometric validation is planned for the future to further explore the reliability, and validity of the new questionnaire in a larger caregiver sample.

Project description:PurposeWe evaluate the face, content, and construct validity of a portable hip arthroscopy module in a regional orthopaedic unit.MethodsParticipants were recruited from a regional orthopaedic centre, and categorized into novice (0 arthroscopies), intermediate (1-29 arthroscopies), and expert (>50 arthroscopies) groups based on reported experience in arthroscopy. Face and content validity was evaluated by feedback from users immediately following completion of modules. Objective measurements, including time taken and subjective measurements consisting of simulation software metrics including, cam lesion locations attempts, scope strikes on bone, healthy bone burred, and cam lesion burred. Scores achieved by experts were recorded, and the median score was set at the level at which proficiency was demonstrated. Participant feedback on perceived educational use was collected following completion.ResultsIn total, 20 participant results were included for analysis. Good face and content validity was expressed by participants with previous arthroscopic experience. Number of scope strikes within the simulator-derived metrics accurately discerned between levels of experience. Novices had a mean of 5 strikes per attempt (SD ±5), intermediates a mean of 5.8 strikes (SD ± 4.1). There was a significant difference between expert and novice groups (P = .01), and expert and intermediate groups (P = .002). No significant difference between overall performance scores achieved by participants in expert, intermediate, and novice groups (62% ±19 vs 55% ±22 vs 50% ±23, P = .15). This demonstrates incomplete construct validity of the simulator software-derived metrics.ConclusionsThis hip arthroscopy simulator demonstrated acceptable face and content validity, with incomplete construct validity of simulator software metrics. Participants reported high levels of satisfaction with the module, highlighting that the addition of haptic feedback would be beneficial to improve procedural steps. Incorporation of tactile feedback to the modulator components would likely enable the software to accurately delineate between levels of experience.Clinical relevanceThis study demonstrates good face and content validity. The addition of haptic feedback in a hip arthroscopy simulator may improve learning.
