Caregiver burden, attachment and cognitive emotion among the family caregivers of severe mental illness patients

Abstract Background Serious mental illness (SMI) is a debilitating medical condition that causes stress and challenges for the family caregivers (FCs) of affected patients, increasing their caregiver burden (CB). This situation can activate attachment styles (AS) and trigger negative emotions, further contributing to CB. Given that AS and cognitive-emotional regulation (CER) can affect the CB of FCs of patients with SMI, the aim of this study was to evaluate the relationship between CB with AS, and CER among the FCs. Methods This cross-sectional descriptive-correlational study was carried out in May–November 2022. Participants were 278 FCs of patients with SMI consecutively recruited from Roozbeh leading psychiatric hospital, Tehran, Iran. Data were collected using a patients’ demographic and clinical characteristics questionnaire, an FCs’ demographic characteristics questionnaire, the Attachment Style Questionnaire, the Cognitive Emotion Regulation Questionnaire, and the Burden Scale for Family Caregivers, and were analyzed using the SPSS software (v. 16.0). Results CB had significant inverse relationship with secure AS (r = − 0.262) and significant positive relationship with fearful AS (r = 0.194) and dismissive AS (r = 0.242) (P
