Systematic review of risk and protective factors associated with substance use and abuse in individuals with autism spectrum disorders.

LAY ABSTRACT: Symptoms characteristic of autism spectrum disorder were initially believed to protect individuals with autism spectrum disorder from developing substance abuse. However, recent studies suggest that up to 36% of individuals with autism spectrum disorder may have a co-occurring issue with substance abuse. In addition, substance abuse may worsen the difficulties with daily functioning some individuals with autism spectrum disorder experience. It is important to understand occurrence rates, and risk, protective and positive treatment factors of co-occurring autism spectrum disorder and substance abuse in order to promote the best possible support for this special population. This review aimed to find and synthesize evidence regarding risk, protective and treatment factors, and determine a general prevalence rate of co-occurring autism spectrum disorder and substance abuse from all studies on substance use and abuse in individuals with autism spectrum disorder. The review also aimed to assess study quality and identify a diagnostic measure for substance abuse in individuals with autism spectrum disorder. Twenty-six studies on substance use and abuse in autism spectrum disorder were included in the review. The rates of substance abuse among those with autism spectrum disorder identified by included studies ranged from 1.3% to 36%, but due to large differences in study methods, a general prevalence rate could not be determined. Risk and protective factors, recognized in the general population, such as familial substance abuse and co-occurring mental health issues, and factors which may be more likely to occur in individuals with autism spectrum disorder, such as limited social resources and low sensation-seeking, were identified. No diagnostic measures specific to individuals with autism spectrum disorder and substance abuse were identified. This review identified only one exploratory study on an adapted intervention for co-occurring autism spectrum disorder and substance abuse. However, there were many methodological challenges in this study that limit the conclusions that can be drawn from the data. More research, using consistent methods, is needed to understand risk and protective factors and to determine the prevalence of substance abuse among individuals with autism spectrum disorder. The potential for co-occurring autism spectrum disorder and substance abuse should be considered by professional working in both autism spectrum disorder and substance abuse services, as finding suggests substance abuse is possible among individuals with autism spectrum disorder and may occur more frequently than previously believed. In addition, autism spectrum disorder and substance abuse service providers should be sensitive to specific risk and protective factors identified by the review that may impact substance abuse course and outcomes.

[Life events and trauma in chronic negligent mothers]. / Evénements de vie et traumatismes chez les mères négligentes chroniques.

The present study examines more closely the chronic behaviors of maltreating mothers. Events that these mothers have experienced during childhood are examined, experiences including abuse, placement, separation, bereavement, rejection, neglect, lack of love and role reversal. Signs of unresolved trauma found in the discourse of mothers, such as dissociation, are also studied. It is proposed that negligent mothers from the chronic group will evoke more negative experiences and/or more intense negative experiences which occurred during childhood than the mothers from the transitory group. The chronic group will also show more signs of dissociation. From a six years follow-up study, a sample of 20 mothers was recruited from the Child Protection Services, including the cases of 10 chronic maltreating mothers and 10 transitory maltreating mothers. Two main measures were used: the Child Abuse Potential Inventory (CAPI) and the Adult Attachment Interview (AAI) (Main et Goldwyn, 1998). The experiences from childhood and complete discourse in AAI were analysed with the method used by Main et Goldwyn (1998). Non parametric analysis indicate that mothers from the chronic group evoke more negative and very negative childhood experiences than the mothers from the transitory group. Content analysis show that chronic maltreating mothers relate having gone through more potentially traumatic events such as foster care placements, separations and abuse. The analysis of the Adult Attachment Interview according to Main and Goldwyn's system demonstrate that the majority of the chronic maltreating mothers have two times more unresolved traumas.
