Introduction & Theoretical Background
This is a Cognitive Behavioral Model Of Persistent Postural Perceptual Dizziness (PPPD: previously termed ‘chronic subjective dizziness’) adapted from Whalley & Cane (2017). PPPD is a form of persistent dizziness which is maintained by psychological factors. The model bears similarities to other models of health anxiety, and can be considered a specific implementation of such a model. It identifies key maintenance mechanisms which serve to prolong dizziness in PPPD. These include appraisals of balance symptoms, behavioral adaptation strategies (including avoidance and safety behaviors), and attentional adaptation strategies (including vigilance, checking, and some involuntary processes).
