Understanding ABA Therapy: What Parents Need to Know
Applied Behaviour Analysis (ABA) is often recommended for autistic children, but many parents don't fully understand what it involves.
What Is ABA Therapy?
The Basics
ABA is a type of therapy based on the science of learning and behaviour. It focuses on:
- Increasing helpful behaviours (communication, social skills, daily living)
- Decreasing challenging behaviours (tantrums, aggression, self-injury)
- Teaching new skills by breaking them into manageable steps
The Evidence Base
ABA is the most researched autism intervention:
- 40+ years of peer-reviewed studies
- Recognized as effective by:
- Surgeon General of the United States
- American Academy of Pediatrics
- National Institute of Mental Health
- Ontario Ministry of Children, Community and Social Services
How Does ABA Work?
Assessment
Every ABA program starts with assessment:
- Skill assessment: What can your child do now?
- Behaviour assessment: Why is challenging behaviour happening?
- Preference assessment: What motivates your child?
Goal Setting
Based on assessment, the team sets SMART goals:
- Specific: Clear and defined
- Measurable: Can observe and count progress
- Achievable: Realistic for your child
- Relevant: Important for your child's life
- Time-bound: Clear target date
Teaching Methods
Common ABA teaching strategies:
- Discrete Trial Training (DTT): Structured, repeated practice
- Natural Environment Training (NET): Learning during play and daily activities
- Pivotal Response Training (PRT): Child-directed learning
- Verbal Behavior (VB): Focus on communication
Data Collection
Progress is tracked through:
- Daily session notes
- Skill tracking charts
- Behaviour frequency counts
- Parent feedback
What Does ABA Look Like?
Typical Session
A typical ABA session might include:
- Warm-up (5-10 min): Relationship-building, preferred activities
- Skill building (30-60 min): Working on specific goals
- Breaks: As needed for regulation
- Practice in natural contexts
- Parent wrap-up (5-10 min): Review progress and homework
Intensity Levels
Research supports 10-40 hours per week depending on:
- Your child's age
- Current skill levels
- Family goals
- Other therapies/services
Finding a Quality ABA Provider
Red Flags
⚠️ Avoid providers who:
- Use punishment or aversive strategies
- Won't let parents observe sessions
- Don't track progress with data
- Make guarantees about "cure"
- Won't collaborate with other professionals
Green Flags
✓ Look for providers who:
- Use positive reinforcement primarily
- Encourage parent involvement
- Share data regularly
- Individualize programs
- Continuously train their staff
- Are Board Certified Behavior Analysts (BCBA) or supervised by one
Important Considerations
The Controversy
Some autistic adults criticize historical ABA practices. Modern ABA emphasizes:
- Assent (child agrees to participate)
- Individualized goals (not compliance for its own sake)
- Quality of life outcomes
- Neurodiversity-affirming approaches
Your Role as Parent
You are essential to your child's success:
- Collaborate on goal setting
- Practice skills between sessions
- Provide feedback to the team
- Advocate for your child's needs
