This study investigated the association between adverse childhood experiences (ACE) and positive psychotic symptoms in Singapore. The findings showed that individuals exposed to dysfunctional home environments or multiple ACE were at an elevated risk of experiencing positive psychotic symptoms.
Background: Epidemiological studies show that adverse childhood experiences (ACE) are associated with positive psychotic symptoms in Western populations; however, there is a lack of population-based data in multi-ethnic, Asian societies. Objective: We investigated the associations between ACE (type and dosage) and positive psychotic symptoms in a nationally representative study in Singapore. Participants and setting: A total of 4441 adult Singapore residents were recruited via door-to-door surveys; they were assessed for ACE and positive psychotic symptoms (i.e., hallucinations, delusions, thought insertion, thought control, and telepathic powers) on structured interviews. Methods: Lifetime experiences of positive psychotic symptoms were regressed on (1) the experience of any ACE; (2) cumulative ACE; and (3) the experience of either no ACE, interpersonal victimization only, dysfunctional home environments only, neglect only or multiple exposures to ACE in weighted and adjusted regression models. Results: 5.2 % of the sample experienced positive psychotic symptoms during their lifetime. Individuals exposed to dysfunctional home environments (OR = 2.84, 95 % CI 1.26 to 6.37) and multiple adverse childhood experiences (OR = 3.31, 95 % CI 2.18 to 5.01) were at an elevated risk of experiencing positive psychotic symptoms. The exposure to three or more ACE was associated with a near five-fold higher risk of experiencing positive psychotic symptoms (OR = 4.51, 95 % CI 2.89 to 7.05). Conclusions: Individuals exposed to dysfunctional home environments or multiple adverse childhood experiences are at an elevated risk of experiencing positive psychotic symptoms. Given the intrafamilial nature of these childhood adversities, dual-generation approaches and family-centered interventions are key.
