Understanding experiences of non-physical maltreatment in childhood in Canada: What is the relationship with suicidal ideation and mental health disorders?

Abstract

Background Physical and sexual childhood abuse are associated with suicidal ideation and mental health disorders. However, less is known about non-physical types of maltreatment. This study examined associations between non-physical types of child maltreatment (e.g., emotional abuse, interpersonal aggression, exposure to physical intimate partner violence, emotional and physical neglect) and suicidal ideation, and mental health disorders. Data and methods Data from the 2018 Survey of Safety in Public and Private Spaces were used to estimate the proportion of individuals 15 years and older in Canada who experienced non-physical maltreatment during childhood. Multivariable regression analyses were used to examine associations between five types of non-physical child maltreatment and suicidal ideation, and mental health disorders. Results Overall, interpersonal aggression was the most common (45.7%), followed by emotional abuse (40.4%) and emotional neglect (20.0%). Individuals who experienced any type of non-physical maltreatment in childhood had a higher probability of lifetime suicidal ideation than those who never experienced the maltreatment examined. Mood disorder diagnoses were more likely among those who experienced emotional abuse, interpersonal aggression, and emotional neglect than among those who never experienced these types of maltreatment. Compared with those who never experienced the maltreatment examined, individuals who experienced emotional abuse, interpersonal aggression, emotional neglect, or physical neglect were more likely to be diagnosed with an anxiety disorder. Diagnoses of post-traumatic stress disorder were more likely among those who experienced emotional and physical neglect than among those who never experienced these types of maltreatment. Interpretation Non-physical child maltreatment is associated with suicidal ideation and mental health disorders. The findings highlight the importance of including non-physical types of child maltreatment on population-based surveys to differentiate associations with mental health outcomes to better align interventions and policies.
