Dr Joachim Diederich

Psychologist

I am a clinical psychologist with decades of experience in both psychological assessment and evidence-based therapy. Over the course of my career, I have worked with a broad range of clients across the lifespan, with a particular focus on adults presenting with Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD). I am committed to providing high-quality, comprehensive services that lead to meaningful and lasting improvements in my clients’ lives. I provide detailed and nuanced assessments for ASD and ADHD in adults. These assessments are designed to develop a clear understanding of how a person thinks, communicates, and manages everyday demands. The process typically includes an in-depth clinical interview covering developmental history and current functioning, the use of standardised diagnostic instruments and questionnaires, and, where appropriate, input from partners or family members. The outcome is not only a diagnostic opinion, but also a practical, individualised set of recommendations to guide support, workplace adjustments, and therapy planning. In addition to assessment work, I offer psychological therapy tailored to each individual’s needs and goals. My therapeutic approach is grounded in evidence-based methods, particularly Cognitive Behaviour Therapy (CBT) and Rational Emotive Therapy (RET). Therapy focuses on identifying and modifying unhelpful thinking patterns, improving emotional regulation, and supporting clients in developing effective strategies for managing daily challenges. I work collaboratively with clients to achieve clear, measurable outcomes and to build skills that promote long-term wellbeing. My practice is guided by a strong commitment to helping clients better understand themselves and to make meaningful changes in their lives. Whether through assessment or therapy, my goal is to provide a supportive, respectful, and professional environment in which clients feel heard, understood, and empowered. Currently, I conduct he following assessments: Autism assessments ADHD assessments Personality assessments Behavioural assessments Cognitive assessments Mental health assessments
