Therapist Proficiency Index (TPI) or Therapist's effectiveness scale

TPI is developed by Professors Wongpakaran and Wongpakaran. This questionnaire is designed to evaluate the therapist’s effectiveness based on 14 key attributes of an effective psychotherapist. These attributes include interpersonal skills, knowledge, adaptability, and the ability to build trust and rapport with clients. Your responses will help identify strengths and areas for improvement.

The list is based on the best available evidence (see e.g., Anderson, Ogles, Patterson, Lambert, & Vermeersch, 2009; Baldwin, Wampold, & Imel, 2007; Duncan, Miller, Hubble, & Wampold, 2010; Lambert, Harmon, Slade, Whipple, & Hawkins, 2005; Norcross, 2011; Wampold, 2007) as well as theory and policy (e.g., APA Presidential Task Force on Evidence-Based Practice, 2006).
