You're trying to figure out why your client keeps repeating the same self-sabotaging behavior, and nothing you've tried has stuck.
Maybe you've heard about the Motivation Assessment Scale (MAS) and wondered if it could help. Or you stumbled on it in a therapist's toolkit and thought, "Wait, can coaches use this?"
Here's the thing. The MAS is a well-validated tool, but it was built for a specific job. This guide walks through the 4 subscales, a step-by-step scoring example with real numbers, how the tool is used in ABA practice, and 7 motivation assessments that fit coaching work better.
What Is the Motivation Assessment Scale (MAS)?
The Motivation Assessment Scale (MAS) is a 16-item rating questionnaire that identifies why a specific problem behavior happens. It doesn't measure how motivated someone is to succeed at life. It measures which of four reinforcers is keeping a behavior going.
That distinction matters. Most people hear "motivation assessment" and picture a career-coaching worksheet. The MAS is different. It's a functional assessment used mostly in Applied Behavior Analysis (ABA), special education, and clinical psychology.
The tool asks someone who knows the individual well (a parent, teacher, or caregiver) to rate how often a behavior happens in 16 different situations. Each question maps to one of four possible functions: Sensory, Escape, Attention, or Tangible.
Once you know the function, you can design an intervention that matches the cause. A child who screams to get attention needs a different response than a child who screams to escape a loud classroom, even if the scream sounds identical from the outside.
Who Developed the Motivation Assessment Scale?
The MAS was created by Dr. V. Mark Durand and Dr. Daniel Crimmins and first published in 1988 in the Journal of Autism and Developmental Disorders. It uses 16 questions rated on a 7-point scale (0 = never, 6 = always).
Durand and Crimmins built the tool to solve a real clinical problem. Behavior analysts needed a fast, standardized way to hypothesize why a behavior was happening before designing an intervention. A full functional analysis takes hours and a trained clinician. The MAS takes about 10 minutes and can be filled out by anyone who knows the client well.
What Are the 4 Subscales of the MAS?
The MAS has four subscales, and each one is a possible reason the behavior keeps happening:
- Sensory — the behavior itself feels good or provides internal stimulation
- Escape — the behavior helps the person avoid or get out of a task, demand, or situation
- Attention — the behavior reliably gets a reaction from someone else
- Tangible — the behavior gets the person access to a specific item or activity
Each of the 16 questions on the MAS maps to one of these subscales. Four questions per subscale. Every question is rated from 0 (never) to 6 (always), so each subscale has a possible score range of 0 to 24.
Let's walk through each one.
1. Sensory
Sensory-maintained behavior happens because it feels good internally, not because of anything happening in the environment. The behavior is its own reward.
Behavior examples: hand-flapping when alone, rocking back and forth, humming repetitive sounds, skin-picking in a quiet room with no one watching.
How it shows up on the MAS: Questions like "Would the behavior occur continuously, over and over, if this person was left alone for long periods of time?" score high when sensory is the function.
Coach application: The underlying idea is useful for coaches. Some habits are self-soothing and have no external audience. If your client has a habit they want to break, ask whether it still serves them when no one's watching. Habits that persist in solitude usually need a replacement behavior, not willpower.
2. Escape
Escape-maintained behavior gets the person out of something they don't want to do. Demands, transitions, unpleasant tasks, or social situations.
Behavior examples: tantrums right before homework time, "forgetting" the assignment, headaches that appear only on meeting days, sudden shutdowns when a difficult topic comes up.
How it shows up on the MAS: "Does the behavior occur following a request to perform a difficult task?" scoring high is a strong escape indicator.
Coach application: This one translates well to coaching. How often do clients have a "work emergency" on the day of a hard session? Or suddenly reschedule when a breakthrough is near? That's escape behavior, and naming it gently ("I notice we tend to hit friction right before big decisions") can be a useful intervention.
3. Attention
Attention-maintained behavior reliably produces a reaction from someone else. The reaction can be positive or negative. What matters is that the person gets engaged with.
Behavior examples: acting out in class, interrupting, dramatic sighing in meetings, oversharing on social media, creating low-stakes crises that pull others in.
How it shows up on the MAS: "Does this behavior occur whenever you stop attending to this person?" is the classic attention marker.
Coach application: Adult clients rarely scream for attention, but the pattern still shows up in subtle ways. The client who bombards you with check-in emails. The one who manufactures crises right before a goal deadline. Recognizing attention as a function, without judgment, can open up a conversation about unmet connection needs.
4. Tangible
Tangible-maintained behavior gets the person a specific item or activity. It's the most transactional function.
Behavior examples: a child screaming in a checkout line until they get candy, an employee throwing a mini-tantrum until they get the assignment they wanted, a teenager negotiating harder and harder until they get the phone back.
How it shows up on the MAS: "Does this behavior occur when you take away a favorite toy, food, or activity?" scoring high is a tangible signal.
Coach application: In adult coaching, the "tangible" often isn't a physical object. It's a specific outcome the client has decided they need. A promotion. A number on the scale. A specific partner. When behavior is rigidly tied to one particular reward, widening what counts as success often dissolves the pattern.
How Do You Score the MAS? Step-by-Step
Scoring the MAS is straightforward once you've seen it done. Here's the exact process, followed by a worked example with real numbers.
Step 1: Collect the responses
The rater (a parent, teacher, or caregiver who knows the individual) answers all 16 questions using this scale:
- 0 = Never
- 1 = Almost never
- 2 = Seldom
- 3 = Half the time
- 4 = Usually
- 5 = Almost always
- 6 = Always
Every question belongs to one subscale (Sensory, Escape, Attention, or Tangible). The standard MAS answer sheet groups the 4 questions per subscale, so you don't have to memorize which is which.
Step 2: Sum each subscale
Add up the four scores within each subscale. You'll end up with four subscale totals, each between 0 and 24.
Step 3: Calculate the mean
Divide each subscale total by 4 (the number of questions per subscale). This gives you a mean score between 0 and 6 for each function.
Step 4: Rank the subscales
Rank the four mean scores from highest (1) to lowest (4). The highest-ranked subscale is the primary hypothesized function of the behavior.
Step 5: Check for relative differences
The raw score matters, but so does how much the top subscale stands out from the others. A subscale that's 1.5+ points higher than the next one is a strong signal. A tight cluster (all four within half a point) usually means the behavior has multiple functions, or the rater doesn't have a clear read on it yet.
Worked Example: Scoring a MAS for "Jamie"
Say you're assessing a 9-year-old named Jamie for disruptive calling-out during class. A teacher has filled out the MAS. Raw scores:
- Sensory: 1 + 2 + 0 + 1 = 4 (mean = 1.0)
- Escape: 5 + 4 + 6 + 5 = 20 (mean = 5.0)
- Attention: 3 + 4 + 3 + 4 = 14 (mean = 3.5)
- Tangible: 1 + 0 + 2 + 1 = 4 (mean = 1.0)
Ranking: Escape (5.0), Attention (3.5), Sensory and Tangible tied at 1.0.
Interpretation: Escape is clearly the primary function. It's 1.5 points above Attention, which is a meaningful gap. Jamie's calling-out likely happens when the work feels too hard and he's trying to derail the demand. Attention may be a secondary driver, but the intervention should start with adjusting task difficulty or offering break cards. Pure attention-extinction could actually make things worse here.
How to Interpret MAS Scores
The mean score on each subscale tells you two things: how likely that function is, and how confident you can be in the result. A rough guide:
- 0.0 – 1.5: Unlikely function. Rule it out as a primary driver.
- 1.6 – 3.0: Possible function. Worth considering, especially with observation.
- 3.1 – 4.5: Likely function. Probably part of what's keeping the behavior going.
- 4.6 – 6.0: Very likely function. Strong candidate for the primary driver.
A couple of extra rules:
The gap matters more than the absolute score. A top subscale of 4.2 that's 2 points above the next one is a clearer result than a 5.5 that's only 0.3 above the next.
Cross-check with direct observation. The MAS is informant-based. It relies on someone's memory and interpretation. It's a hypothesis generator, not a final diagnosis.
Multiple functions are common. If two subscales are within a point of each other and both above 3, the behavior likely serves more than one function depending on context.
Common Mistakes in MAS Scoring
Even experienced raters trip over the MAS. Watch for these.
1. Using it for behaviors that are too broad. The MAS assesses one specific behavior at a time. "Misbehaves" is not a behavior. "Hits peers during transitions" is. Vague targets turn every answer into a guess.
2. Rating how the behavior feels, not how often it occurs. A frustrated parent might rate everything as "always." Anchor the rater back to frequency before they start.
3. Having the wrong person rate it. The rater needs to have observed the behavior across multiple contexts. A teacher who only sees it during math can't accurately score questions about what happens when the person is alone.
4. Treating a flat profile as a failure. If all four subscales come out within half a point, that's data too. The behavior is likely multiply-maintained. Move to direct observation.
5. Stopping at the MAS. The MAS is a starting point, not the whole assessment. Pair it with direct observation, ABC data, or a full functional analysis before finalizing an intervention.
6. Confusing the MAS with the MAS-II. They're related but not identical. See the next section.
MAS vs MAS-II: What's the Difference?
You'll sometimes see the tool referred to as MAS-II. Here's the quick version.
The original MAS (Durand & Crimmins, 1988) has 16 questions, 4 subscales, and a 0–6 rating scale. It remains the standard reference in most ABA literature.
The MAS-II is a revised version that refined some question wording and updated the scoring interpretation guidelines. It still uses 16 items and the same four subscales. The changes were incremental, not structural.
For most practical purposes the two are used interchangeably. If you're publishing research or following a specific clinical protocol, check which version your institution requires. Related tools like the QABF and FAST exist as alternatives to both.
MAS in the ABA Context (and Why It Matters)
Most people searching for the Motivation Assessment Scale are ABA therapists, BCBAs, special education teachers, or students studying behavior analysis. If that's you, here's the short version.
The MAS is one of the most common indirect functional assessment tools in ABA. It's not a replacement for a functional analysis. It's a screening tool that helps you form a hypothesis before committing to a full FA or observation protocol.
In practice, ABA teams use the MAS to:
- Generate an initial hypothesis about behavior function
- Involve parents and teachers in the assessment process
- Triangulate with direct observation data
- Track whether the function of a behavior shifts after intervention
If you're a coach who ended up here by accident, welcome. This tool isn't really built for you, but plenty of motivation assessments are. Keep reading for seven that fit coaching work much better.
Can Coaches Use the Motivation Assessment Scale?
Short answer: probably not as intended.
The MAS is a clinical tool for functional behavior assessment. It's designed to identify reinforcers maintaining a problem behavior, usually in children or adults with developmental disabilities. Coaches don't diagnose or treat behavior disorders.
That said, the framework behind the MAS is genuinely useful. The idea that behavior serves a function that falls into a small number of categories can unlock a conversation that generic goal-setting can't. Knowing whether a client's stuck pattern is about avoidance, connection-seeking, self-soothing, or chasing a specific outcome changes how you respond.
7 Types of Motivational Assessments for Coaches
Here are seven motivation assessments that give you insight into your client's drivers and preferences. Use them to help clients get clear on their goals and to guide your coaching process.
Motivational Maps
Motivational Maps are built around nine key motivators, grouped into achievement, autonomy, and creativity. Your client takes it as a self-assessment questionnaire and brings the results to your session. You get a clear read on their intrinsic drivers, which helps you align their goals with the actions they'll actually take.
CliftonStrengths
CliftonStrengths (previously known as StrengthsFinder) identifies your client's top strengths from 34 talent themes. Use it to help clients recognize and apply their strengths so they can work with their natural ability instead of against it.
VIA Character Strengths Assessment
The VIA Character Strengths Assessment looks at 24 character strengths, like kindness, perseverance, and leadership. Use it to help clients understand their core virtues and values, so their choices line up with who they actually are.
DISC Personality Assessment
The DISC Personality Assessment sorts people into four main personality types: Dominance, Influence, Steadiness, and Conscientiousness. It surfaces your client's work preferences and interpersonal dynamics, so they can communicate their style to loved ones, teammates, and supervisors, and handle conflict better.
Myers-Briggs Type Indicator (MBTI)
The Myers-Briggs Type Indicator (MBTI) assesses personality across four dichotomies, which produces 16 personality types. The results tell you a lot about what naturally drives someone at work and in relationships. Use it to help clients understand their tendencies, what gives them meaning, and how they make decisions.
Ikigai
Ikigai is a Japanese concept for the intersection of what you love, what you're good at, what the world needs, and what you can be paid for. Use reflective exercises in your sessions to help your client find their ikigai and get a clearer sense of purpose and direction.
The Wheel of Life
The Wheel of Life visually represents different areas of your client's life: career, health, relationships, and so on. Add 8–12 segments to see what they prioritize and how balanced each area feels.
This tool gives you a concrete basis for talking about satisfaction and fulfillment. Clients can see where things feel out of balance, work out what's driving it, and set goals that actually line up with what matters to them.

Frequently Asked Questions
How do you score the Motivation Assessment Scale?
Add up the four question scores within each subscale (Sensory, Escape, Attention, Tangible), divide each total by 4 to get a mean score between 0 and 6, then rank the four means from highest to lowest. The highest-ranked subscale is the primary hypothesized function of the behavior. A gap of 1.5+ points between the top subscale and the next is a strong signal.
What are the 4 subscales of the MAS?
The four subscales are Sensory (behavior feels good internally), Escape (behavior avoids a demand or situation), Attention (behavior gets a reaction from others), and Tangible (behavior produces access to an item or activity). Each subscale has 4 questions, for a total of 16 items on the assessment.
Is the Motivation Assessment Scale reliable?
Research on the MAS has produced mixed results. It shows good internal consistency and can be a useful screening tool, but inter-rater reliability varies. Different raters assessing the same person sometimes land on different primary functions. Because of this, the MAS is best used as a hypothesis generator and paired with direct observation or a full functional analysis before finalizing an intervention.
What's the difference between the MAS and the MAS-II?
The original MAS (1988) and the MAS-II both use 16 items and the same four subscales. The MAS-II is a revised version with refined wording and updated scoring interpretation, but the underlying structure is the same. In most practical settings the two are used interchangeably. If you're publishing research or following a clinical protocol, check which version your institution requires.
Can coaches use the Motivation Assessment Scale?
The MAS is a clinical tool designed for functional behavior assessment in ABA, special education, and psychology settings. Coaches typically don't use it directly because they don't diagnose or treat behavior disorders. Coaches who want to assess client motivation will find tools like Motivational Maps, CliftonStrengths, DISC, MBTI, VIA Character Strengths, Ikigai, and the Wheel of Life much better suited to their work.
Build the Coaching Practice of Your Dreams
The MAS is a powerful tool in the right hands. If you're a BCBA or ABA therapist, you probably already know that. If you're a coach, the subscales are still worth understanding as a lens, even if the tool itself isn't part of your daily work.
Whichever motivation assessment you end up using with your clients, the admin side of your practice shouldn't get in the way of the work that actually changes lives.
That's where Paperbell comes in. It's an all-in-one client management tool that handles your bookings, contracts, payments, client portal, and more, so you can focus on your clients instead of your inbox.
