Psychological factors of sibling caregivers of patients with severe mental disorders: An observational study

The goal of the present study is to explore the perception of the relationship with parental figures, traumatic experiences, personality traits and psychosocial characteristics of the participant sibling caregivers. The sample was composed of 30 sibling caregivers recruited at psychiatric facilities in Italy, and of 30 control siblings. The battery of instruments administered included Parental Bonding Instrument (PBI), Minnesota Multiphasic Personality Inventory 2 (MMPI-2), and The Inventory of Traumatic Experiences (TEC). This research found that sibling caregivers of patients with severe psychiatric pathologies are distinctly different from the siblings of the control group with respect to the perception of their relationship with parental figures more frequently regarded as dysfunctional, and were also characterized by a higher presence of traumatic experiences. The problematic relationship with parental figures, some traumatic experiences, and the burden of taking care of a sibling with psychiatric disorders are probably important variables with regards to the individual's overall psychological condition.
