Objective:
Studies utilizing the discrepancy model of the Mayo-Portland Adaptability Inventory-4 (MPAI-4) have commonly used the cognitive and physical domains to estimate self-awareness. This study included other aspects of self-awareness such as awareness of one's social and emotional status and daily functioning to explore their effects on caregiver burden for ABI survivors.
Methods:
We studied 64 patient-caregiver pairs up to 29 years post-discharge from a holistic, milieu-oriented outpatient neurorehabilitation program. Discrepancy scores between ABI survivors' and caregivers' reports on the MPAI-4 subscales (i.e. Abilities, Adjustment, and Participation) and Total Score were used to determine self-awareness. Caregiver burden was measured using the Zarit Burden Interview (ZBI).
Results:
Exploratory linear regression analyses revealed that caregiver burden derived from the ZBI was predicted by the discrepancy scores generated from the Abilities (p < 0.0001), Adjustment (p < 0.01), Participation subscales (p = 0.01), and Total Score (p < 0.001), respectively. Among the exploratory models generated, the Total Score model had the highest predictive value (R2 = .33) for caregiver burden.
Conclusions:
Measures of self-awareness should be comprehensive by considering diverse components of self-awareness. Increasing ABI survivors' self-awareness in different domains has the potential to effectively alleviate caregiver burden.
