Autism, Assertiveness and Self-Esteem: Why So Many Autistic People Struggle to Speak Up for Themselves

At our clinic, we meet many autistic children, teenagers and adults who are not only managing the challenges associated with autism itself, but are also struggling with something far less recognised: a profound lack of self-assurance.
Many autistic people tell us:
“I don’t know how to explain what I need.”
“I just go along with things.”
“I feel guilty saying no.”
“I worry people will think I’m rude.”
“I don’t trust my own decisions.”
“I freeze when someone challenges me.”
These difficulties are often misunderstood as “shyness,” “avoidance,” or “low confidence.” In reality, they can stem from years of misunderstanding, invalidation, anxiety, trauma, social confusion and unmet needs.
Assertiveness is not about being confrontational. It is about understanding your rights, recognising your needs, communicating safely, and believing that your voice matters.
For many autistic people, this does not come naturally — not because they are incapable, but because they may never have been taught how.
Why Do Many Autistic People Struggle With Assertiveness?
Autistic individuals often grow up in environments where they are repeatedly corrected, misunderstood or expected to adapt to a world that does not accommodate their differences.
Over time, this can affect self-esteem and identity development.
Common contributing factors include:
Being told they are “too sensitive,” “dramatic,” or “difficult”
Repeated social rejection or bullying
Difficulty interpreting social intentions or hidden meanings
Fear of conflict or confrontation
Masking autistic traits to fit in
Past experiences of humiliation or exclusion
Being ignored when expressing distress
Dependency on others to interpret the world
Anxiety about “getting it wrong”
Limited opportunities for supported decision-making
Trauma from school, relationships, workplaces or family environments
Many autistic people develop a pattern of people-pleasing, compliance or shutdown because it feels safer than risking conflict or rejection.
Unfortunately, this can leave individuals vulnerable to:
Exploitation
Coercive relationships
Workplace difficulties
Burnout
Anxiety disorders
Depression
Emotional dependency
Loss of identity
Chronic self-doubt
Autism and the Difficulty Understanding Rights
Another challenge is that autistic individuals may not automatically understand the unwritten rules surrounding boundaries, consent, fairness and personal rights.
If someone has spent years being told they are “wrong,” they may struggle to recognise when others are treating themunfairly.
Some autistic people:
Accept poor treatment because they believe they must adapt
Struggle to identify emotional manipulation
Find authority figures intimidating
Do not realise they are entitled to accommodations
Fear complaining or “causing trouble”
Do not know how to challenge decisions respectfully
This is particularly concerning in:
Education settings
Employment
Healthcare
Relationships
Social care systems
Autistic individuals are often expected to self-advocate without ever being explicitly taught how.
Anxiety and Assertiveness Are Closely Linked
When somebody does not feel able to express their needs safely, anxiety often increases.
The nervous system begins to remain in a constant state of vigilance:
“What if I upset someone?”
“What if they reject me?”
“What if I misunderstand?”
“What if I’m wrong?”
Over time, avoidance becomes a coping strategy.
Some autistic people avoid:
Phone calls
Appointments
Meetings
Asking questions
Sending emails
Making complaints
Returning items
Discussing problems
Requesting accommodations
What looks like “avoidance” is often fear rooted in past negative experiences.
Self-Esteem Is Built Through Experience
Self-esteem does not develop simply because someone is told they are “good enough.”
It develops through:
Being heard
Feeling safe
Having choices respected
Experiencing success
Being understood
Learning boundaries
Developing competence
Receiving appropriate support
Many autistic people have had the opposite experience.
Repeated failures in communication, social relationships or education can create an internal belief of:
“I can’t cope.”
“Other people know better than me.”
“I shouldn’t speak up.”
“My needs are a burden.”
These beliefs can become deeply ingrained.
What Can Help?
The good news is that assertiveness can be taught.
Self-advocacy is a skill — not a personality trait.
With the right support, autistic individuals can learn to:
Understand their rights
Recognise unhealthy dynamics
Communicate boundaries
Build confidence
Reduce anxiety
Make informed decisions
Advocate for accommodations
Trust their instincts more effectively
Practical Tools That May Help Autistic Individuals
1. Explicit Teaching of Human Rights and Neurodiversity
Many autistic people benefit from direct teaching around:
Consent
Boundaries
Equality rights
Workplace accommodations
Educational rights
Disability protections
Emotional safety
Reasonable adjustments
Understanding:“I am allowed to need support”can be life-changing.
Teaching should be concrete, visual and repeated regularly.
2. Assertiveness Courses
Assertiveness training can be incredibly valuable when adapted appropriately for autistic learners.
Helpful areas include:
Saying no safely
Using clear communication
Requesting support
Handling disagreements
Managing criticism
Recognising manipulation
Setting boundaries
Understanding tone and body language
Email and workplace communication
Role play, scripts and real-life examples are often more effective than abstract discussion.
Some autistic individuals may require:
Smaller groups
Longer processing time
Reduced sensory demands
Written material beforehand
One-to-one support
3. Advocacy Support
Advocates can play a vital role.
An advocate may:
Attend appointments
Help interpret information
Support communication
Ensure the autistic person’s wishes are heard
Reduce overwhelm
Assist with complaints or disputes
For some individuals, advocacy is not about dependency — it is about accessibility.
Supportive advocacy can help build confidence gradually over time.
4. Therapy That Understands Autism
Traditional therapy can sometimes miss the underlying reasons for low self-esteem in autistic people.
Helpful therapeutic approaches may include:
Trauma-informed therapy
Autism-informed CBT
Compassion-focused approaches
Psychoeducation
Identity-focused work
Emotional literacy support
Importantly, therapy should not focus solely on “fixing behaviour,” but on understanding lived experience.
5. Teaching Decision-Making Skills
Some autistic people struggle with decision-making because:
They fear consequences
They overanalyse possibilities
They seek certainty
They lack confidence in judgement
They have previously been criticised for mistakes
Breaking decisions into manageable steps can help:
What are my options?
What information do I need?
What feels safe?
What are the risks?
Who can support me?
Decision-making is a skill that improves with practice and support.
6. Building Safe Relationships
Healthy relationships are fundamental to confidence.
Autistic people benefit from relationships where:
Communication is clear
Needs are respected
Boundaries are accepted
Mistakes are tolerated
Differences are understood
Unfortunately, many autistic individuals have experienced relationships where they felt controlled, criticised or misunderstood.
Learning what healthy relationships look like is essential.
7. Supporting Self-Advocacy Early
Children should not have to wait until adulthood to learn self-advocacy.
We should be teaching autistic young people:
How to ask for help
How to express discomfort
How to identify emotions
How to disagree respectfully
How to recognise unsafe situations
That their voice matters
When children are consistently spoken for rather than spoken with, confidence can be unintentionally reduced.
You Can Do Something About It
Many autistic people have spent years believing:
They are the problem
Their needs are unreasonable
Their feelings are invalid
They should stay quiet
This is not an autism problem alone. It is often the result of environments that have not understood or supported autistic communication and emotional needs effectively.
Confidence can be rebuilt.
Assertiveness can be learned.
Self-worth can grow.
With the right support, autistic individuals can develop the skills needed to:
express needs clearly,
understand their rights,
navigate relationships more safely,
reduce anxiety,
and participate in the world with greater confidence and autonomy.
Every autistic person deserves to feel heard, respected and safe enough to use their voice.
The Centre for Clinical Interventions (CCI) has an excellent free self-help workbook called “Assert Yourself”, which many autistic adults may find useful when learning about boundaries, communication and self-advocacy.
