Final answer:
Alison is most likely engaging in client-centered or person-centered therapy, a non-directive form of psychotherapy where the therapist provides support and reframes concerns without giving directive advice.
Step-by-step explanation:
Alison and her therapist's approach, where the therapist reframes Alison's concerns to help her focus her thoughts more effectively, and where Alison controls the length and frequency of her sessions, is indicative of a client-centered or person-centered therapy.
This therapeutic modality, developed by Carl Rogers, emphasizes the therapist providing a supportive environment in which the client leads the process of their own healing. The therapist offers unconditional positive regard, empathetic understanding, and congruence (authenticity), rather than directive advice or interpretations.
Considering other psychotherapeutic approaches like cognitive-behavioral therapy, which focuses on cognitive processes and behaviors, or more directive therapies such as Freudian psychoanalysis, which delves into childhood experiences and subconscious thoughts, Alison's therapy style is markedly aligned with the principles of client-centered therapy.
