Evidence-Based Techniques for Online Care

Harriet Marritz brings several evidence-based approaches to online therapy that focus on practical skills and emotional regulation. Solution-focused Cognitive Behavioral Therapy emphasizes identifying specific goals and using structured, actionable strategies to change unhelpful thinking and behavior patterns - it is useful for anxiety, depression, and stress-related concerns.

Dialectical Behavior Therapy offers concrete tools for managing intense emotions, reducing self-harm behaviors, and improving interpersonal effectiveness. Motivational Interviewing supports people who are ambivalent about change by exploring values and enhancing internal motivation for healthier choices.

Finding the right approach is collaborative - Harriet works with each person to determine which combination of techniques best fits their needs, goals, and preferences, and adjusts the plan as progress is made.

Online therapy options include video calls, phone sessions, live chat, and text-based messaging, offering flexibility to fit appointments into busy schedules. These formats make it easier to access licensed professionals from home or during travel, accommodate different communication styles, and allow ongoing support between scheduled sessions when needed.
