The initial meeting with an individual seeking rehabilitation services sets the foundation for a recovery-oriented, person-centered relationship. The CPRP Exam Blueprint (Domain I: Interpersonal Competencies) emphasizes building trust and rapport as the primary objective to engage individuals effectively (Task I.B.3: "Adapt communication strategies to build trust and engagement"). Option D (establishing a trusting relationship) aligns with this, as trust is essential for fostering collaboration, understanding the individual’s needs, and ensuring future engagement in rehabilitation planning.

Option A (creating the rehabilitation plan) is premature, as planning requires trust and assessment (Domain IV). Option B (reducing symptoms) is a clinical goal, not the focus of an initial meeting in psychiatric rehabilitation. Option C (determining the diagnosis) is outside the scope of rehabilitation practitioners, who focus on functional goals, not diagnostic assessment. The PRA Study Guide underscores trust-building as the cornerstone of initial interactions, supporting Option D.
