AbstractDespite the growing body of research on chronic pain in adults with osteogenesis imperfecta (OI), there is still a lack of comprehensive understanding of the influence of psychological factors on pain experienced by individuals with this condition. This study aims to delve into the correlation between personality traits and various aspects of pain, such as frequency, intensity, appraisal, and coping mechanisms, in a significant sample of adults with OI. Additionally, the investigation seeks to identify whether certain personality profiles may be more susceptible to chronic pain within this specific population. A descriptive cross-sectional study was conducted on a sample of 418 adults diagnosed with OI. Participants completed an online survey that assessed sociodemographic and clinical variables, pain parameters, personality traits, pain appraisal, and coping strategies. Subsequently, descriptive, correlational, cluster and comparative analyses were performed. Up to 83% of the participants reported experiencing pain on a regular basis. Regarding personality dimensions, moderate scores were obtained, with no significant differences compared to the general population. Neuroticism emerged as the trait showing the most robust relationships with the evaluated variables. It positively correlated with pain intensity, frequency, and the perception of pain as threatening (P < .001). Conversely, higher levels of extraversion were associated with a reduction in pain and its threatening perception (P < .001). Finally, the cluster analysis revealed a personality profile that showed greater vulnerability in pain adaptation, characterized by high levels of neuroticism and low levels of extraversion, agreeableness, and conscientiousness. Chronic pain is prevalent in adults with OI. Personality dimensions maintain a significant relationship with this pain, acting as vulnerability or protective factors. Consequently, specific personality profiles are associated with poorer adaptation. Understanding these profiles would allow for a deeper comprehension of the pain experience in adults with OI.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
