Pain Catastrophizing as Amplified Pain Wrong Attractor: Rumination, Magnification, and Helplessness as Basin-Deepening Mechanisms in the Chronic Pain Landscape

We apply the Displacement Framework to Pain Catastrophizing (Sullivan's Pain Catastrophizing Scale, 1995), formalizing it as W_cat — a three-component wrong attractor that amplifies D(ξ_pain) beyond nociceptive signal through synergistic basin-deepening mechanisms. The proportionate pain processing ground state S⁰_pain is defined with functional descending inhibitory control (PAG-RVM) enabling calibrated pain responses.

W_cat is maintained by three independently and synergistically deepening mechanisms: rumination (inability to disengage attention from pain, constituting an attentional amplifier of D(ξ_pain)), magnification (threat appraisal inflation of worst-case pain meaning), and helplessness (perceived inability to modulate pain removing coping agency and self-confirming through learned helplessness).

Nine formal propositions cover: S⁰_pain definition (P1), W_cat three-component architecture (P2), rumination as attentional amplifier (P3), magnification as threat appraisal distortion (P4), helplessness as return-path blocking (P5), the catastrophizing-central sensitization bidirectional cycle (P6), the Vlaeyen/Linton fear-avoidance cascade from catastrophizing through kinesiophobia, avoidance, disuse, and deconditioning (P7), psychological interventions as return paths — CBT targeting magnification, ACT/mindfulness targeting rumination, pain neuroscience education as landscape reconceptualization (P8), and surgical outcome prediction — W_cat must be addressed pre-surgically as it predicts post-surgical pain independently of surgical success (P9).

Catastrophizing in fibromyalgia, chronic low back pain, pediatric pain, and opioid use are analyzed.
