Indirect assessment
Indirect assessment gathers information about a problem behavior from people who know the client, through interviews, questionnaires or rating scales, without directly observing it.
Caregivers, teachers, staff and sometimes the client can describe when, where and with whom a behavior happens, what usually happens before it, and how others typically respond. Indirect assessment collects that information in a structured way. Examples include functional assessment interviews and rating scales or questionnaires such as the Questions About Behavioral Function (QABF), the Motivation Assessment Scale (MAS) and the Functional Analysis Screening Tool (FAST).
Indirect methods are quick, require no special setup and can cover settings and times the team cannot observe. They are often the first step of a functional behavior assessment, helping the supervisor define the behavior and decide what to observe or test next.
Their main limit is that they depend on memory and opinion. Informants may disagree, recall only dramatic incidents, or interpret rather than describe. As a result, indirect assessments should not be used alone to determine function; they are combined with direct observation and, when appropriate, a functional analysis. RBTs might help schedule interviews or pass on questionnaire information, and they should share caregiver reports with the supervisor objectively.
Example and non-example
| Example | A supervisor interviews a client's parent about when head-banging happens, and the parent completes a rating scale about likely reasons for the behavior. |
|---|---|
| Non-example | An RBT recording each head-banging episode and what happened before and after it during sessions is descriptive assessment, because the behavior is observed directly. |
Don't confuse it with
| Descriptive assessment | Indirect assessment relies on others' reports; descriptive assessment directly observes the behavior in the natural setting. |
|---|---|
| Functional analysis | Indirect assessment asks about the behavior; functional analysis directly tests variables to show what maintains it. |

Question 1A supervisor asks a caregiver to fill out a questionnaire about which dressing and grooming skills their teenager does without help at home. What kind of skill assessment method is this?
Show answer
C: An indirect assessment. Questionnaires, interviews and rating scales collect information from people who know the client instead of observing the client directly. These are indirect methods.
- A: Direct observation means watching the client perform the skill and recording it.
- B: A functional analysis tests the function of problem behavior by arranging conditions.
- D: Permanent product recording measures a lasting outcome of behavior, such as completed worksheets.

Question 2A caregiver reports that their child dresses without help at home. During direct assessment at the clinic, the child needs physical prompts for most dressing steps. What should the RBT do?
Show answer
C: Record what was observed and tell the supervisor about both reports. Differences between caregiver report and direct observation are useful information. The RBT records what they saw and reports both to the supervisor, who interprets them.
- A: Direct observation showed prompts were needed, so scoring mastery would ignore the data.
- B: The child may do the skill differently at home; the RBT should not judge the report.
- D: The RBT was asked to record direct observation, so leaving it out loses key data.

Question 3Which list names the three general types of functional assessment methods?
Show answer
A: Indirect assessment, descriptive assessment and functional analysis. Functional assessment includes indirect methods (interviews, rating scales), descriptive methods (direct observation in the natural setting, such as ABC data) and functional analysis (testing conditions directly).
- B: These are other kinds of assessments, not functional assessment methods.
- C: These are continuous measurement procedures.
- D: These are phases of intervention, not assessment methods.
