How Debates About Masking Influence Choices Between ABA Therapy and Relationship-Based Alternatives for Autism?
Masking has become one of the most important ideas shaping modern autism discussion. Many autistic people describe masking as hiding their natural traits in order to fit in socially. The National Autistic Society explains that masking is a strategy some autistic people use “to appear non-autistic in order to blend in”.
NHS services also recognise the pressure masking creates. Some children can appear regulated at school but experience a meltdown at home because they have been holding everything in throughout the day.
As families become more aware of masking, they often ask how it should influence choices between ABA therapy and relationship-based developmental approaches such as DIR/Floortime or Naturalistic Developmental Behavioural Interventions. This blog brings together what is known, what is not known and how UK guidance frames the issue.
Masking, mental health and lived experience
Research from autistic people and peer-reviewed studies shows that masking is linked to significant mental health risks. One study found that “more masking was associated with a concurrent higher level of perceived stress” (Sage Journals). Autistic-led qualitative research describes masking as exhausting and even harmful. Participants in one study said that the effort of hiding their autistic traits contributed to burnout and suicidal thoughts (PMC).
A systematic review concluded that camouflaging appears to be a risk factor for anxiety and depression in autistic adults without intellectual disability (PMC). NAS summarises the issue clearly: autistic people who mask frequently tend to experience more anxiety and depression and may be at greater mental health risk.
Although the evidence is strong on mental health outcomes, UK clinical guidance from NHS and NICE does not yet directly address masking in the context of autism therapies.
Does ABA encourage masking? What the evidence does and does not show
Some autistic adults worry that certain ABA practices may encourage children to suppress natural autistic behaviours such as stimming, eye looking or sensory regulation, which can feel similar to masking. These concerns appear in autistic-led blogs and community discussions.
However, there are no randomised trials or empirical studies showing that ABA increases masking. There are also no studies showing that ABA reduces masking. One ABA industry article distinguishes ABA from masking but does not provide research that connects the two (Daytastic ABA).
NICE guidance for autistic adults and children does not mention masking in discussions of behavioural interventions or psychosocial interventions. This creates an evidence gap. Many autistic adults report that they felt pressured to behave in neurotypical ways during childhood interventions, but these experiences have not yet been systematically studied.
Relationship-based alternatives and masking
Relationship-based therapies such as DIR/Floortime take a different stance. They emphasise emotional safety, coregulation, shared enjoyment and child-led interaction. DIR/Floortime is described as promoting “relationships and emotional connections” rather than trained performance of specific behaviours (Floortime overview).
Because these approaches focus on acceptance and connection, many families feel they are less likely to create masking pressure. But there are no peer-reviewed studies measuring whether DIR/Floortime, NDBIs or parent-mediated interventions reduce masking.
NICE guidelines recommend play-based, relationship-focused social communication interventions, but do not discuss masking or compare interventions in relation to masking risk. So relationship-based therapies may philosophically align with reducing masking, but empirical evidence is still missing.
How UK guidance frames behaviour, communication and wellbeing
While masking is not explicitly referenced, UK clinical guidance already aligns more closely with interventions that promote emotional safety and acceptance.
NHS recommends supporting communication through simple language, visual supports and emotional regulation rather than correcting behaviours.
NICE CG170 recommends early social communication interventions involving play, shared attention and reciprocal engagement rather than compliance drills.
NICE NG11 emphasises understanding the reasons behind behaviour, including sensory and emotional triggers, and using functional, supportive strategies rather than punishment or suppression.
NAS strongly encourages non-coercive, rights-based support and warns against approaches that aim to make someone appear “less autistic”.
Together, these guidelines promote approaches that reduce the need to mask even though they do not use the word “masking”.
Takeaway
Masking has major implications for mental health, identity and long-term wellbeing. Although no research directly compares how ABA or relationship-based interventions affect masking, autistic-led accounts suggest that therapies focused on compliance or behaviour normalisation may increase pressure to hide autistic traits. Relationship-based interventions emphasise emotional safety and acceptance, which aligns with autistic-affirming values, but they also lack direct masking data.
UK guidance from NHS, NICE and NAS leans toward approaches that prioritise emotional regulation, communication support, sensory understanding and respectful behavioural intervention. For families deciding between ABA and developmental alternatives, the most meaningful question may be: which approach helps the child feel safest being their authentic self?
