Background: Type D personality, or the ââ?¬Å?distressed personalityââ?¬Â, is a psychosocial factor associated with negative\r\nhealth outcomes, although its impact in younger populations is unclear. The purpose of this study was to\r\ninvestigate the prevalence of Type D personality and the associations between Type D personality and\r\npsychosomatic symptoms and musculoskeletal pain among adolescences.\r\nMethods: A population-based, self-reported cross-sectional study conducted in VÃ?¤stmanland, Sweden with a cohort\r\nof 5012 students in the age between 15ââ?¬â??18 years old. The participants completed the anonymous questionnaire\r\nSurvey of Adolescent Life in VÃ?¤stmanland 2008 during class hour. Psychosomatic symptoms and musculoskeletal\r\npain were measured through index measuring the presence of symptoms and how common they were. DS14 and\r\nits two component subscales of negative affectivity (NA) and social inhibition (SI) were measured as well.\r\nResults: There was a difference depending on sex, where 10.4% among boys and 14.6% among girls (p = < 0.001)\r\nwere defined as Type D personality. Boys and girls with a Type D personality had an approximately 2-fold increased\r\nodds of musculoskeletal pain and a 5-fold increased odds of psychosomatic symptoms. The subscale NA explained\r\nmost of the relationship between Type D personality and psychosomatic symptoms and musculoskeletal pain.
