Diversity in intervention adds difficulty to the already complicated planning in an intervention. Introducing diversity means to be especially sensitive to populations that vary in values, life styles, or situations. The first two components of the interpersonal styles that are in our society are acculturation and bi-cultural individuals.

Acculturated individuals mostly identify with the white society class. Examples of acculturated individuals are African Americans and Latinos, who typically fit in with the white middle class in America. These African Americans and Latinos would be living in white neighborhoods, be friends with white adults, and have mainly white colleagues. The spouse of the acculturated individual, however, may not identify or describe his/or her spouse as having acculturated into white society to the extent that is correct. Also, involving the extended family into the treatment plan is not as important with an acculturated individual.

Bi-cultural is the other component of intervention with diverse individuals. The bi-cultural individual is slightly more immersed in his/or her own culture than the acculturated individual. However, he/or she will still have a relatively easy time interacting with white society. The life of the bi-cultural individual will be integrated in all areas including work, living environment, and entertainment. Their friends will integrate with them as well, mixing between white to Latino to African American to Native Americans. When treating these individuals, involving the extended family in the process becomes more significant. In fact, it is beneficial for the entire treatment to be integrated in many areas to ensure the individual's maximum comfort.
