International Development of Applied Behavior Analysis as a Profession

Mueller (2025) looked at how ABA is growing outside the United States.

The paper tells the story of new ABA groups forming in many countries.

Each group builds its own rules, training, and local culture.

ABA is no longer just a branch of psychology.

It is turning into a stand-alone world profession.

Different nations shape the field to fit their own cultures.

Kazdin (1975) first showed ABA ideas spreading into nine different fields.

Mueller now shows the same spread, but across whole countries.

Mazefsky (2015) cheered ABA for leaving U.S. psychology groups.

Mueller scales that idea worldwide, showing many nations doing the same.

Graber et al. (2025) warn that too many reform brands could split the field.

Mueller’s view answers that fear: many local brands can coexist under one global profession.

Delgado et al. (2024) give a tool for blending client goals with cultural values.

Mueller’s call for culturally tailored pathways fits that tool perfectly.

If you train staff, lobby for licensure, or write policies, think bigger than U.S. boards.

Help build local credentials that honor your region’s language, values, and laws.
