Affective temperaments in caregiver of patients with bipolar disorder and their relation to caregiver burden.

Background: Bipolar disorder (BD) is impose a severe burden on caregivers. The aspects of the burden should be evaluated from broad perspective, because caregivers contribute greatly to the treatment process. Affective temperaments are widely distributed in the population, in their mild forms can provide adaptive properties. The aim of this study was to assess the affective temperaments among caregiver of patients with BD and to evaluate the impact of affective temperaments on the burden.

Methods: The study sample included 101 caregivers of patients diagnosed with BD type I according to DSM-5 and 107 healthy volunteers. The Temperament Evaluation of the Memphis, Pisa, Paris and San Diego self-report questionnaire (TEMPS-A), Hamilton Depression Rating Scale (HDRS), and Hamilton Anxiety Rating Scale (HARS) were administered to both groups, and the Burden Assessment Scale (BAS) was administered to caregivers.

Results: The hyperthymic and depressive temperament scores were higher in the caregivers than in the controls, and hyperthymic and depressive temperaments were predictor factors for caregiver. Irritable temperament also adversely affected the caregiver burden, but hyperthymic temperament was not related to development of burden. The mean BAS score was 43.2 ± 11 for the caregivers. The caregiver HDRS and HARS scores and the number of manic episodes were related to the level of burden.

Limitation: Cross-sectional study CONCLUSION: Affective temperaments may be related to being a caregiver and to the caregiver burden. Hyperthymic and depressive temperaments may indicate predisposition for being a caregiver. Irritable temperament adversely affects burden, whereas hyperthymic temperament could protect the caregiver from burden.
