Integrating CBT and Mindfulness for Online Care

Dr. Mattes commonly draws from Cognitive Behavioral Therapy to help people identify and change unhelpful thinking and behavior patterns, offering structured tools for anxiety, depression, panic, and executive functioning challenges. Acceptance and Commitment Therapy complements CBT by encouraging values-based action and learning to relate differently to difficult thoughts and feelings, which can be useful for chronic stress, caregiver strain, and life purpose questions. Client-centered techniques provide a supportive, collaborative stance that centers the client's experience and goals while building self-acceptance and motivation.

Choosing the right approach is part of the therapeutic process, and she works collaboratively with clients to determine what methods best match their needs, preferences, and progress. Treatment plans may blend elements across approaches and are adjusted over time based on what is most helpful for each individual.

Online sessions are offered via video calls, phone sessions, live chat, or text-based messaging to increase flexibility and access. These options make it easier to fit therapy into busy schedules, support continuity of care across locations within Indiana, and allow clients to use formats that suit their communication style and daily life.
