The Future of Behaviour Management Has Finally Caught Up

by Dr. Bob Carey

Over the past four decades, I have had the privilege of working with thousands of children, adolescents, and adults whose lives have been affected by developmental disabilities, autism, mental health challenges, acquired brain injuries, and complex behavioural concerns. Throughout those years, I have witnessed significant changes in how psychology and behaviour analysis understand and respond to challenging behaviour. Some of these changes have been driven by advances in research, while others have emerged through the lived experiences of individuals, families, and professionals who have challenged us to think differently about what behaviour means and how best to support meaningful change. Looking back, I find it encouraging that many of the ideas now being embraced across psychology, Applied Behaviour Analysis (ABA), Positive Behaviour Support, and developmental disability services are remarkably consistent with principles that have guided the Positive Systems Approach for many years.

When I first developed the Positive Systems Approach back in the 1980’s my goal was never to replace the science of behaviour analysis. On the contrary, I believed that behavioural principles provided an essential foundation for understanding learning and behaviour. At the same time, with my training in a clinical psychology graduate program (Western University), I recognized that behaviour could not be fully understood by examining the individual in isolation. Human behaviour is influenced by a complex interaction of biological, psychological, social, environmental, and organizational factors, and meaningful intervention requires us to consider each of these influences. I believed that effective support begins by understanding the whole person within the context of the systems in which they live, learn, work, and develop. Increasingly, I have found this broader perspective is being reflected in contemporary psychological practice.

One of the most significant developments in recent years has been the widespread adoption of trauma-informed care. Across virtually every area of psychology and human services, professionals are becoming more aware that challenging behaviours often represent adaptive responses to adversity, chronic stress, anxiety, loss, or traumatic experiences rather than simple acts of defiance or noncompliance. This shift has encouraged clinicians to move beyond asking, "What is wrong with this person?" toward the much more meaningful question, "What has happened to this person, and how have these experiences shaped the way they cope with the world?" This subtle but important change in perspective reflects a growing appreciation that behaviour often represents an individual's best attempt to manage circumstances that exceed their current coping abilities. Long before trauma-informed practice became widely recognized, the Positive Systems Approach emphasized the importance of understanding the personal history, emotional experiences, and environmental circumstances that give rise to behaviour. Rather than viewing behaviour as the problem itself, we have always regarded it as valuable information that helps us understand the individual's experience.

I recall working with a young man whose aggressive outbursts at his group home had become increasingly severe. Traditional behaviour management strategies focused on consequences for hitting and destroying property, yet little changed. When we broadened the assessment beyond the behaviour itself, it became clear that the outbursts almost always occurred following unexpected changes in routine or after periods of heightened sensory stimulation. His behaviour was not driven by defiance but by overwhelming anxiety and an inability to communicate his distress before reaching a crisis point. Once the agency who was supporting him introduced predictable routines, visual schedules, sensory breaks, and more proactive communication strategies, the aggressive incidents declined dramatically. The young man had not changed nearly as much as the system around him had.

Closely related to this is the growing recognition that behaviour is fundamentally a form of communication. This principle has become increasingly prominent in both psychology and behaviour analysis, particularly when working with individuals who have autism, intellectual disabilities, or limited verbal communication skills. Every behaviour serves a purpose, although that purpose is not always immediately apparent. Behaviour may communicate fear, confusion, frustration, loneliness, physical discomfort, sensory overload, uncertainty, or a need for predictability and support. Two individuals may display identical behaviours for entirely different reasons, and effective intervention depends upon understanding those differences rather than assuming that the observable behaviour tells the entire story. Functional Behaviour Assessment has long emphasized identifying the function of behaviour, but contemporary practice increasingly acknowledges that emotional well-being, physical health, developmental level, trauma history, social relationships, and environmental demands all interact to influence why behaviours occur. This more comprehensive understanding aligns closely with the principles of Positive Systems Approach, which has consistently encouraged professionals to look beyond the behaviour itself in order to understand the multiple interacting factors that contribute to its occurrence.

I remember another individual, an adult with autism who frequently became physically aggressive toward residential staff during evening routines. Previous intervention plans had focused almost exclusively on reducing aggression through behavioural strategies. A more comprehensive assessment revealed that the behaviour occurred almost exclusively when staff hurried him through transitions at the end of the day. His communication difficulties made it difficult for him to express that he simply needed more time to process changes and complete tasks at his own pace. Once staff slowed the pace of interactions, provided advance notice before transitions, and allowed greater flexibility in evening routines, the aggression became infrequent. What had initially appeared to be a behavioural problem was, in reality, a communication problem combined with environmental demands that exceeded his coping abilities.

Another encouraging development has been the increasing emphasis on compassion, therapeutic relationships, and human dignity within behaviour analysis. Historically, behaviour analysis has sometimes been criticized for placing too much emphasis on observable behaviour while giving insufficient attention to the individual's emotional experience and the importance of trust and collaboration. Although this characterization has never accurately reflected the work of many thoughtful behaviour analysts, the profession has nevertheless evolved in important ways. There is now considerably greater recognition that meaningful learning occurs within the context of positive relationships and that individuals are more likely to engage in intervention when they feel respected, understood, and emotionally safe. Concepts such as therapeutic rapport, assent-based practice, self-determination, and collaboration with families have become increasingly important within contemporary behavioural practice. These developments do not weaken the science of behaviour analysis; rather, they strengthen it by recognizing that effective intervention depends not only on technical competence but also on the quality of the relationships that support learning and change.

Similarly, there has been growing attention to the importance of preserving individual dignity throughout the intervention process. Increasingly, professionals recognize that success cannot be measured solely by reductions in challenging behaviour. Meaningful outcomes also include greater independence, increased opportunities for choice, stronger social relationships, improved quality of life, and participation in meaningful community activities. Individuals are no longer viewed simply as recipients of services but as active participants whose goals, preferences, and values deserve careful consideration. This evolution reflects a broader understanding that behavioural intervention should support personal growth rather than simply promote compliance. These principles have always been central to the Positive Systems Approach, which emphasizes recognizing individual strengths, respecting personal autonomy whenever possible, and helping people build lives that are both meaningful and personally satisfying.

Perhaps the aspect of Positive Systems Approach that appears most consistent with current developments is its emphasis on systems thinking. Behaviour does not occur in isolation, nor can it be fully understood without considering the environments in which it develops. Families, schools, workplaces, service agencies, organizational cultures, physical environments, community resources, and public policies all influence behaviour, often in ways that are subtle but highly significant. Over the years, I have frequently observed situations in which extensive efforts were directed toward changing an individual's behaviour while relatively little attention was given to modifying the surrounding environment. In many cases, relatively modest changes within the system—greater consistency among caregivers, improved communication, clearer expectations, enhanced staff training, environmental adaptations, or stronger collaboration between professionals and families—produced far more meaningful improvements than additional behavioural programming directed solely at the individual.

One family I worked with illustrates this point particularly well. Their teenage son, who had autism and an intellectual disability, experienced frequent behavioural crises at home despite multiple intervention plans. As we explored the family's daily routines, it became apparent that everyone was responding differently to his behaviour. Expectations varied from one caregiver to another, routines changed from day to day, and communication among professionals was limited. Rather than introducing another behaviour program, we focused on helping the adults become more consistent, improving communication between home and school, and establishing predictable routines that everyone followed. Within a few months, behavioural incidents had decreased substantially. Nothing about the young man's diagnosis had changed; what changed was the consistency and predictability of the system surrounding him. Experiences such as this have reinforced my belief that when we change systems, we often change behaviour.

There has also been an important shift from crisis management toward prevention. For many years, behavioural intervention often focused primarily on responding effectively once challenging behaviour had already occurred. Contemporary practice increasingly emphasizes identifying and modifying the conditions that make challenging behaviour more or less likely to occur in the first place. Predictable routines, meaningful engagement, effective communication supports, appropriate sensory accommodations, positive social relationships, physical health, adequate sleep, and emotionally supportive environments all contribute to reducing behavioural risk before difficulties escalate. This proactive perspective has long been a defining characteristic of the Positive Systems Approach. Preventing behavioural crises is almost always more effective, less intrusive, and ultimately more humane than repeatedly managing crises after they occur.

Another noteworthy trend has been the growing recognition that effective intervention must be individualized. Although evidence-based practices provide valuable guidance, no single intervention is appropriate for every individual or every circumstance. Two people may display similar behaviours while requiring entirely different supports because the factors influencing those behaviours differ substantially. One individual may struggle primarily with anxiety, another with sensory processing difficulties, another with communication limitations, and another with chronic medical issues or emotional trauma. Appreciating these individual differences requires comprehensive assessment and careful clinical judgment rather than reliance on standardized intervention packages. The Positive Systems Approach has consistently emphasized this individualized perspective by encouraging professionals to understand each person's unique strengths, challenges, experiences, motivations, relationships, and environmental circumstances before developing intervention plans.

Some observers have suggested that the increasing emphasis on trauma-informed care, compassion, systems thinking, and individualized supports represents a departure from traditional behaviour analysis. I view these developments somewhat differently. Rather than replacing behavioural science, they represent a natural evolution toward a more comprehensive understanding of human behaviour. The principles of careful observation, functional assessment, objective measurement, and evidence-based intervention remain as important today as they have ever been. What has changed is our appreciation that behaviour cannot be separated from the broader context of human experience. Scientific precision and genuine compassion are not competing philosophies; they are complementary aspects of effective clinical practice. The most successful interventions are those that integrate sound behavioural science with empathy, collaboration, respect, and a deep understanding of the systems that shape people's lives.

As I reflect on the direction our profession has taken, I am encouraged by the increasing convergence between contemporary psychological practice and the principles that have guided the Positive Systems Approach for more than thirty-five years. Across psychology, behaviour analysis, education, and developmental disability services, there is growing recognition that behaviour is communication, that trauma and emotional well-being matter, that prevention is preferable to crisis management, that meaningful change requires collaboration, and that individuals achieve their greatest potential when the systems around them support success. These developments do not diminish the importance of behavioural science; rather, they enrich it by placing behaviour within the broader context of human relationships, environmental influences, and quality of life. Ultimately, the future of behaviour management is not about choosing between science and compassion, nor between behavioural principles and systems thinking. It is about recognizing that the most effective interventions are those that combine rigorous scientific understanding with genuine respect for the dignity, strengths, and unique experiences of every individual. If there is a single lesson that the field appears to be embracing today, it is one that has guided the Positive Systems Approach from the very beginning: lasting behavioural change is achieved not simply by changing people, but by understanding them and by creating systems that allow them to flourish.
