Background Previous studies assessed the relationship between caregivers’ characteristics and caregiver burden. However, comprehensive evaluations of caregivers’ behavioral and psychological traits remain comparatively limited. Objective To explore the possible association between the cognitive and behavioral characteristics of caregivers of patients with Alzheimer's disease (AD) and the burden they experience, with a focus on sex/gender differences. Methods In this multicenter cross-sectional study within the SINdem “Sex and Gender Differences in Dementia” group, informal caregivers of non-institutionalized AD patients attending the Italian Memory Clinics were enrolled. Caregivers completed the Montreal Cognitive Assessment, Revised Scale for Caregiver Self-Efficacy, 20-Item Toronto Alexithymia Scale, Barratt Impulsiveness Scale-11, Brief COPE, 14-Item Resilience Scale, Ten-Item Big Five Inventory, Five Facet Mindfulness Questionnaire, Empathy Quotient–Short, and the Caregiver Burden Inventory. Sex was considered as a binary variable (female/male); gender-related dimensions were explored indirectly through caregivers’ behavioral and psychological characteristics. Results 238 caregivers and 238 AD patients were enrolled. A higher burden was associated with more daily caregiving hours, lower self-efficacy, greater impulsivity, difficulties identifying feelings, acting without awareness, a stronger tendency to judge, and higher neuroticism. Female caregiver burden was associated with attentional/motor impulsiveness, lower mindfulness, lower resilience, and lower emotional empathy. Male caregivers showed associations with lower self-efficacy, greater reliance on emotion-focused coping, difficulties identifying feelings, lower non-judging, lower agreeableness, and reduced cognitive empathy. Conclusions Caregiver burden was associated with caregivers’ own behavioral and psychological profiles and sex, beyond patient-related factors. These findings support the importance of integrating sex/gender perspectives and targeted interventions into caregiver assessment and support.
