Final answer:
In therapy sessions, the RISB is likely to be used for preference assessment, revealing subconscious aspects of the individual's personality and helping to identify adjustment problems or career counseling needs.
Step-by-step explanation:
Within the therapy sessions described, the therapist or Registered Behavior Technician (RBT) will most likely be using the Rotter Incomplete Sentence Blank (RISB) for preference assessment. This assessment tool includes 40 incomplete sentences that individuals are asked to complete promptly, revealing underlying desires, fears, and personal struggles. The RISB has different forms tailored to school-aged individuals, college students, and adults, making it a suitable and adaptable tool for sessions. Given the focus on exploring subconscious elements of personality, the RISB can be employed across therapy sessions to capture potentially evolving or emerging patterns relevant to the individual's mental health and personal development.
