Childhood trauma is associated with prolonged treatment delays in psychosis patients, with higher CTQ scores predicting longer DUP. Patients with schizophrenia-spectrum psychosis have longer help-seeking and total DUPs compared to those with affective psychosis. Increased positive symptoms predict longer help-seeking DUPs, while more severe negative symptoms predict longer referral DUPs. Social disadvantage indicators do not impact DUP.
Apart from increasing risk for psychotic disorders, childhood adversity has been associated with worse outcomes. One way in which childhood adversity may worsen outcomes is by lengthening treatment delays, which are associated with negative impacts. We tested the influence of childhood trauma on treatment delays, measured as the duration of untreated psychosis (DUP), and its help-seeking and referral components, in a first-episode psychosis cohort (N = 203). We accounted for pertinent social (e.g., migrant status) and other determinants (i.e., age at onset, diagnosis, symptoms) of treatment delays. Multiple linear regression analyses revealed that for a one-unit increase in Childhood Trauma Questionnaire (CTQ) scores, average overall DUP increased by 25%. Higher CTQ scores also significantly predicted help-seeking and referral DUPs. Patients with schizophrenia-spectrum psychosis had longer help-seeking and total DUPs than those with affective psychosis. More severe positive symptoms predicted longer help-seeking DUPs, while more severe negative symptoms predicted longer referral DUPs. Indicators of social disadvantage did not affect DUP. Our results show that childhood trauma increases DUP by prolonging the help-seeking process and delaying access to mental healthcare even after help is sought. Early identification of psychosis among populations with trauma histories seems warranted and can likely positively impact outcomes.
