Mental health care use of autistic adults: Identifying longitudinal patterns using sequence analysis

Many autistic adults experience co-occurring mental health problems, which have a negative effect on their well-being and result in increased use of mental health services. To improve mental healthcare for autistic adults, a better understanding is needed of what type of support they use in real life. Clinical guidelines recommend three kinds of mental health interventions: therapy, counseling, and medication. We investigated the use of these types of interventions in a sample of 445 autistic adults (aged 18-87 years) across a 5-to-7-year period. We found evidence for four different patterns of intervention use, or so-called subgroups: (1) , (2) , (3) , and (4) . The group with mixed intervention use consisted of relatively more females and individuals with co-occurring psychiatric conditions, especially compared to the subgroup with the least intervention use. It appeared that many, but not all, autistic individuals used mental health services for an extended period. However, there was considerable variability in the type, combination, and duration of intervention use. This means that determining the optimal support for autistic adults is often a complex task, which requires collaboration of clinical experts and autistic individuals themselves, to make informed decisions.
