The document discusses foundational interpersonal skills for providers, including listening without judgment, asking open-ended questions, affirming clients, reflective listening, and summarizing. Some key skills are using open-ended questions to explore clients' thinking, affirming their strengths and positive behaviors, reflecting back what clients say to deepen understanding, and summarizing conversations to transition to new topics or get feedback. Developing these foundational skills helps providers understand clients better and move away from just giving advice.
