You Have Developed a New Form of Behavioral Therapy for People

Essay

You have developed a new form of behavioral therapy for people with various conduct disorders, and you think it is a relatively robust treatment. Specifically, the therapy has been successful when it was practiced in your private clinical office and in a public park, and it has been successful across various age groups (e.g., children, teens, middle-age, seniors). However, whenever another researcher tries to replicate your treatment implementation, or when individuals attempt to reproduce what they have seen you do on television, no one seems to be able to achieve the same levels of success that you do (and your argument is that others have less success because "they aren't doing it right"). That is not to say your results are fabricated; indeed, your therapy works, just only when you administer it.
In this example, how would you classify the validity and generalizability of your behavioral therapy? Is it an externally valid therapeutic technique if only you can implement it successfully? How generalizable is it?
