In autism care, behavior is everything. It’s the main indicator for diagnosis and one of the main areas of focus for treatment. Autistic children engage in many different behaviors, and we as professionals take note. Indirect assessments in ABA therapy (and outside therapy) also play a key role in this process. They offer a way to understand the functions behind behaviors without requiring direct observation.
These assessments mainly rely on parent and caregiver reports, questionnaires, and interviews. Indirect assessments help to provide a more well-rounded view by focusing on the perspectives of those who interact with the child daily.
While direct assessments are vital and the primary type of assessment, this article will focus on indirect methods. Direct assessments can be resource-intensive and may not always capture the complete picture. Indirect assessments allow caregivers to share information to look at a child’s behavior over time and across different settings. This can help promote more effective autism care, and that’s what matters.
Understanding Indirect Assessments
Indirect assessments are exactly like they sound: indirect. They involve using secondary sources like interviews, surveys, and existing records, rather than relying on direct observation of behaviors. These assessments are crucial for obtaining a broader perspective on an individual’s actions. Sometimes, behaviors may only happen in certain settings or with certain people. What may happen very frequently at home may not happen a single time in a controlled setting at a doctor’s office. Indirect assessments also allow us a chance to receive input from teachers, parents, and peers.
The importance of indirect assessments lies in their ability to look into behavior in natural settings without spending a lot of time and resources. While we can’t expect indirect sources to be perfect, they can help to better put the things learned during direct observation into context. These assessments are also particularly useful in informing intervention plans since they can help to identify triggers and environmental factors that affect behavior.
Common Indirect Assessment Tools in Autism Care

- Questions About Behavioral Function (QABF)
The Questions About Behavioral Function (QABF) is used to identify the functions of behavior in individuals with autism. Sometimes the behavior is obvious but the reason behind it is less apparent. The QABF assesses the different possible functions of behavior (which are attention-seeking, escape, access to tangibles, and sensory stimulation). Once we know the reason a behavior is occurring, we can work on creating a treatment plan that works on all levels. - Functional Analysis Screening Tool (FAST)
The Functional Analysis Screening Tool (FAST) identifies factors influencing problem behaviors in autistic children. It can uncover potential triggers and maintaining consequences (that is, results of a behavior that make the behavior continue to occur). The FAST also focuses heavily on the functions of behavior. The information gathered through the FAST offers insights that help caregivers and professionals understand the context of challenging behaviors. This, again, allows professionals to make the best possible decisions when it comes to treatment planning. - Motivation Assessment Scale (MAS)
The Motivation Assessment Scale (MAS) looks at motivations behind repetitive behaviors. When caregivers notice recurring behaviors that disrupt daily life, the MAS helps clarify their underlying motivations. The MAS, unsurprisingly, looks at the functions of behavior. It is certainly a common theme in all of these assessments. The functions of behavior are almost as, if not more important than the actual behaviors themselves. - Functional Assessment Interview (FAI)
The Functional Assessment Interview (FAI) is a part of a bigger assessment on behavior. It includes structured interviews that go into their history, environment, and specific instances of challenging behavior. If you assumed this type of assessment also looks at the functions of behavior, awesome! The insights gained from the FAI help professionals develop hypotheses about behavior triggers and functions.

Integrating Results from Indirect Assessments
Professionals use information from indirect assessment tools to diagnose and plan individualized interventions. Using the data from the tools mentioned above helps practitioners identify the possible functions (reasons) for a behavior happening. They can also help to determine if there are specific things that make the behavior change in frequency or intensity. They allow for targeted strategies that address root causes, not just symptoms.
This is essential to any good plan. If the symptoms are treated and the root causes are not addressed, this can cause tremendous problems for the individual in the future. If a behavior plan is created without first knowing a possible reason for the behavior, I would definitely recommend getting a second opinion from another behavioral specialist.
Integrating data from multiple sources deepens understanding and treatment accuracy. Direct observation isn’t always reliable and indirect assessments aren’t always completely accurate. Like most areas of healthcare, more information means better treatment.
Benefits of Using Indirect Assessments
As mentioned a few times already, indirect assessments provide several important benefits. They offer insights into the context surrounding behaviors, which aren’t always obvious with direct assessments. This is vital for a reliable and ethical treatment plan, better outcomes, and a better-adapted client. In addition, it gives professionals a better understanding of the caregiver’s perspective. Caregiver input and collaboration are crucial to care.
Challenges and Considerations

As useful as they are, indirect assessments also come with potential challenges. The main concerns about indirect assessments relate to accuracy. For instance, caregivers may unintentionally skew responses based on their perceptions or emotions. Parents may not report a behavior to be as severe as it is because they’ve been dealing with it long enough that it feels more routine to them, leading to a diminished sense of alarm. Or, they may believe a behavior is more severe than it is because they are incredibly alarmed when it occurs.
To address these challenges, behavior professionals usually corroborate findings with other assessment types, such as direct observations or tests, to give a more balanced view.
Additionally, providing comprehensive training for evaluators helps ensure that they understand how to administer assessments effectively and interpret the results objectively. Things like asking leading questions or asking questions that are too vague can hurt results.
Collaborating with Professionals
Collaboration between healthcare providers is, of course, very important, but with parents, it is absolutely necessary. Parents should openly communicate any concerns or observations about their child’s behavior. It is always helpful to add examples too.
Parents shouldn’t ever worry about what behavioral professionals will think about a particular behavior. I have come across parents who are worried about judgment about certain behaviors, and I am here to promise that is not something that parents should be concerned about. We as behavioral professionals would never judge a child or family based on the behaviors they may engage in. We care about helping the child thrive more than anything and are very understanding about problem behaviors that can occur.
Parents may also benefit from keeping records of behaviors, noting possible patterns and triggers. Any information about before, during, or after a behavior occurs can be incredibly helpful. This can also help avoid forgetting to mention certain behaviors that have occurred. Finally, staying engaged throughout the process, from initial assessments to follow-up discussions, allows for better alignment and collaboration on intervention strategies.
Conclusion
Direct assessments are obviously invaluable, but indirect assessments are key for the why, how, when, where, and who when it comes to behavior. These help to make the intervention plans helpful for both the child and the family. For most kids, problem behaviors are a way of communicating things that they need. Simply decreasing behaviors can be done easily, but doing so in a way that is ethical and practical requires more than just data points.
