An ISTDP Guide to Recognizing the Three Anxiety Pathways


In Intensive Short-Term Dynamic Psychotherapy (ISTDP), anxiety is assessed by observing how it is expressed in the body. Rather than relying only on what patients report, therapists look for specific physiological patterns that reveal a person’s current capacity to regulate emotion.

  • Somatomotor (Striated Muscle): Muscular tension follows a characteristic sequence through the body and is generally the most adaptive pathway.
  • Sympathetic: Dry mouth, sweating, cold hands, blushing, increased heart rate, and shivering reflect sympathetic activation.
  • Parasympathetic: Nausea, diarrhoea, dizziness, urinary urgency, fainting, drowsiness, and jelly legs indicate reduced anxiety tolerance.
  • Cognitive & Perceptual Disruption: When anxiety exceeds the patient’s capacity, thinking and perception become disrupted, signaling the need to regulate anxiety before further emotional exploration.
  • Clinical Pearl: Assess which channel predominates, how quickly anxiety rises, how widely it spreads, how long it lasts, and how quickly it subsides. These observations guide the pace of therapy.
