- Abstract
Neuropeptide Y (NPY) is a 36-amino acid peptide that is widely expressed throughout the limbic system. Recent evidence has highlighted NPY as a marker of resilience to posttraumatic psychopathology, which may be due to its association with neural regions involved with emotion regulation. This study examined whether plasma NPY levels moderated the relationship between emotion regulation and psychopathology in a sample of adult survivors of childhood interpersonal trauma, a population known to be at high risk for psychopathology. Adults exposed to an interpersonal criterion A trauma during childhood (N = 54) were recruited from an urban population at a midwestern medical center and completed a baseline study visit as part of a larger clinical trial. Participants gave a blood sample in order to assess circulating levels of NPY and answered questions related to emotion regulation and mood-related pathology. Results of a moderated multiple regression showed that the overall model was significant R
2 = 0.26, F (5, 48) = 3.46, p < .01. Difficulties in emotion regulation was significantly predictive of psychopathology (unstandardized B = 0.032, p < .01), and this relationship was significantly moderated by levels of NPY (unstandardized B = -0.001, p < .05) such that the relationship between emotion regulation and psychopathology was weaker for those with higher levels of NPY. Results suggest that higher levels of NPY may lessen the association between emotion regulation and posttraumatic psychopathology in survivors of childhood interpersonal trauma. Further investigation of the contribution of NPY to psychopathology in this population is warranted.
