Abstract
The primary goal of the study was to assess the relationship between personality dispositions, coping styles, immune markers, clinical status, and subjective somatic symptoms in a mixed sample of HIV positive individuals. Specifically, the prognostic value of psychological and immunological measures in HIV progression was emphasized. Subjects (n = 104) were recruited from a cohort of 422 HIV positive individuals enrolled in the Oslo HIV Cohort Study. The partkipants were given self-administered questionnaires assessing behavioral, psychological, and psychdal variables. Clinical assessment and immunological tests were performed at regular follow-up visits. Clinical status was assessed according to the Centers for Disurse Control criteria. The immune markers used were CD4 T cell counts, beta2-microglobulin concentration, sewn levels of HIV-1 p24 core protein, and levels of antibodies to core protein. In addition, subjective somatic symptoms were assessed. The results showed that measure-s of negative affectivity (NA; e.g. anxiety, distress, tension) were consistently related to subjective somatic symptoms and passivedefensive coping style. However, no amistent association between NA measures and immune markers was found. Individuals who developed AIDS in the study period had significantly lower initial CD4 cell counts as well as lower scores on measures of active-pmblem related wping (e.g. Positive reappraisal, Seeking social support) and passivedefensive coping (i.e. Escape-Avoidance, Self-control). The results suggest (1) that coping styles may merit a specific focus in future research of psychological factors and medical outcomes in HIV infection, and (2) because of associations of NA measures with symptom reports studies of the relationship between e.g. stress, depression and HIV outcome should consider these variables as confounders.
