In Adlerian therapy, life style is influenced by:

• A. Birth order, sibling interactions, parent interactions, and the client's sense of their position in the family.
• B. Only current symptoms.
• C. Random genetic factors.
• D. Not relevant.

Answer: (A)

In Adlerian theory, lifestyle (style of life) is shaped by the person’s early social world, especially the family environment. This includes how birth order and sibling interactions, as well as parental interactions, influence the individual, along with how the person perceives their own position in the family. This early relational context forms the unique pattern the person uses to approach life tasks and cope with feelings of inferiority.

That’s why the statement listing birth order, sibling interactions, parent interactions, and the client’s sense of their position within the family is the best fit. It reflects how Adlerian therapy emphasizes social and familial roots in personality development. The other options overlook this holistic, family- and socially-based formation and instead focus on symptoms, genetics, or deem the factor irrelevant, which don’t align with Adler’s view.
