Serving You

Behavior consultation is a problem-solving, empirically driven process in which a Behavior Analyst identifies and tracks progress on behavioral goals (whether reducing disruptive behavior or teaching new skills). They develop and implement interventions designed to bring about meaningful change on those goals. The effect of these interventions is continuously assessed through direct data they collect, and the interventions are changed or kept based on their proven success. This continues with the purpose of improving clients’ lives through goal achievement.
A behavior assessment is a process through which a Behavior Analyst identifies the specific variables that cause an individual to behave a certain way. This allows the Behavior Analyst to develop an effective treatment plan. The main components of an FBA are typically: systematic direct observation, indirect assessment (questionnaires and interviews), and functional analysis (controlled experiments to determine which variables tend to increase or decrease the behavior).
Boulder Analysts is committed to bringing long-term success to our clients. This involves not only implementing effective plans ourselves, but teaching those that live with our clients every day to implement effective strategies to ensure that adaptive behavior remains long after we have gone.
