Assessments and the Role of the Registered Behavior Technician
Skills Assessments
- Assess a client's or student's skill repertoire within specific skill areas or domains.
- Can focus on one specific skill area (e.g., reading, math) or multiple areas (e.g., academic, social, language, play, daily living, motor skills).
- Purpose: to gather information about a client's current skill set to determine teaching goals.
- Conducted at regular intervals to measure progress and growth over time.
Skill Areas Included:
- Daily living skills: Zipping, using a microwave, pouring a drink.
- Language skills: Making requests, using pronouns, imitating sounds.
- Academic skills: Counting, reading, writing.
- Self-care skills: Putting on a shirt, brushing hair, and tooth brushing.
- Social skills: Greetings, eye contact, conversational skills.
- Motor skills: Stacking blocks, throwing, and kicking.
- Assessment of challenging behaviors.
Methods of Conducting Skills Assessments:
- Interview: Involves questioning the client's teacher and primary caregiver about the student's skills.
- Direct Observation: Assessor observes the client during their normal routine.
- Direct Assessment: Assessor sets up opportunities for the client demonstrate specific skills.
- The assessor does not help the student during the assessment.
Examples of Skills Assessments:
- Vineland Adaptive Behavior Scales: Caregiver and/or teacher based assessment.
- Assessment of Basic Language and Learning Skills Revised (ABLEs): Conducted through direct assessment and observation, covering five skill domains.
- Verbal Behavior Milestones Assessment and Placement Program (VB-MAP): Primarily assesses language skills, based on Skinner's analysis of verbal behavior.
- Assessment of Functional Living Skills (AFLS): Focuses on daily living skills across different environments (home, school, community, vocational settings).
Functional Behavior Assessment (FBA)
- Provides information about the circumstances under which a client demonstrates challenging behavior.
- Helps to hypothesize the function of the challenging behavior.
- Function of a behavior: Refers to the reinforcer that keeps the behavior occurring.
- Identifying the function is critical for developing an effective behavior reduction plan.
Types of FBA Methods:
- Indirect Assessment Methods: Do not involve direct observation, information is obtained from people familiar with the client.
- Forms: Interviews, questionnaires, and checklists.
- Quick to conduct, but may have subjectivity.
- Descriptive Assessment Methods: Involve direct observation of the client during their normal routine, repeated over a number of days to identify patterns and hypothesize function.
- More accurate than indirect assessments but more time intensive.
- Types: ABC recording and scatterplot analysis.
- ABC Recording: Observer writes down what happens before (antecedent) and after (consequence) the target behavior.
- Scatterplot Analysis: The observation period is broken into small intervals, using symbols to indicate the extent to which the target behavior occurred in each interval.
- Empty interval: Zero instances of the target behavior.
- "x": Target behavior occurred.
- Black: Target behavior occurred four or more times.
- Functional Analysis: Involves Experimental assessment during which the potential antecedents and consequences for the challenging behavior are manipulated systematically in a controlled environment.
- Yields the most precise results, but is the most time-intensive.
Preference Assessments
- Used to find out what types of items and activities may function as reinforcers during teaching.
- Informal assessments: Presenting a choice to the client before teaching.
- Formal assessments: collecting items and activities that can be tested in a formal preference assessment, or asked to collect data as your supervisor implements the assessment.
Role of the RBT in Assessments
- Assessments are conducted under guidelines, only individuals with specific training should conduct assessments.
- RBTs do not conduct assessments.
- RBTs can assist supervisors with certain aspects of assessments:
- Participate in reporting and describing behavior.
- Record data for the assessment.
- Assist with inter-observer agreement (IOA) data.
- Assist with certain parts of implementation.
- Reporting and Describing Behavior:
- Filling out questionnaires or participating in interviews.
- Describing challenging behaviors and specific skills.
- Report only what you observed, not personal opinions or what others have said.
- Recording Data:
- Taking data during skills assessments and functional behavior assessments (ABC, scatterplot).
- Taking data during functional analysis sessions.
- Inter-Observer Agreement (IOA):
- Two independent observers take data on the same skill or behavior.
- Ensures the accuracy of collected data.
- Understand the data collection procedure and ask question if needed.
- Assisting with Implementation:
- Setting up materials needed for the assessment.
- Arranging the environment in a certain way.
- Testing for certain skills during sessions, following specific instructions from the supervisor.
