Presentation of Depressive Symptoms in Autism Spectrum Disorders.

BACKGROUND

Depressive disorders are frequently mis- and underdiagnosed in individuals with autism spectrum disorders (ASD).

OBJECTIVE

Our objective was to identify and synthesize current knowledge regarding (1) the presentation of depressive symptoms and (2) the use of self-reports in assessing depressive symptoms in individuals with ASD and comparisons between self-reported and observer-reported symptoms. A scoping review was conducted to capture the full range of literature on the topic and to identify research gaps.

METHODS

Articles were identified through a search of academic literature and screened for relevance to the aims of the review.

RESULTS

In addition to typical depression symptoms, individuals with ASD may demonstrate atypical symptoms such as changes in autistic symptoms, self-injurious behavior, and psychomotor changes. Moreover, the review revealed a bias toward observer-reports of symptoms. Self-reports frequently were not included or were ascribed less weight than observer-reports. Self-reports typically differed from reports given by parents or other caregivers, but a consistent pattern in these differences has not been established.

CONCLUSIONS

Further research on the use of self-reports in assessing depressive symptoms in individuals with ASD is needed. Self-reports may provide information not obtainable through observer-reports, and integrating both self- and observer-reports in psychiatric evaluations may produce more comprehensive and accurate assessments.
