Panic disorder and social anxiety disorder illustrate a shared feedback architecture with different feared outcomes and sources of apparent evidence. Treatment can share collaborative cognitive behavioral methods while changing the experiments, attentional targets and safety behaviors according to the formulation. In both, an anxiety response can become part of the perceived proof of danger. A diagnosis indicates a pattern of difficulty; it does not establish that all cases have an identical maintaining process.

In panic disorder, recurrent unexpected panic attacks are followed by concern or behavioral change related to further attacks. The cognitive account emphasizes catastrophic misinterpretation of bodily sensations: an acceleration of heart rate, dizziness or altered breathing may be interpreted as imminent collapse, loss of control or another catastrophe. The interpretation increases anxiety, which generates further sensations, reinforcing the threat interpretation. Avoidance and safety behaviors can prevent learning that the sensations would have changed without the precaution. Appropriate assessment remains necessary because a cognitive formulation does not determine the medical origin of any individual symptom.

David M. Clark's original account specifies this feedback process rather than equating panic with generally high stress. It predicts that the meaning assigned to a sensation should matter more than its physical presence alone. The same sensation could be frightening in one interpretive context and relatively unremarkable in another. This explanatory distinction is useful because it suggests testable comparisons between predictions, rather than relying solely on relaxation or a verbal assurance that nothing dangerous will occur. The original paper is a model, not itself a randomized demonstration of every link.^[ref]

Social anxiety disorder instead centers on feared scrutiny and negative evaluation. In an interaction, self-focused attention can shift processing from the actual conversation to sensations and an imagined view of oneself. A negative self-image may be treated as if it were an observer's report. Safety behaviors such as mentally rehearsing every sentence or restricting engagement can reduce spontaneity, obscure the evidence needed to test a prediction and sometimes change how the interaction develops. Post-event processing can then select apparent failures and preserve the threatening impression for the next encounter.

The disorders therefore share an interpretive loop but differ in what would count as disconfirming evidence. In panic, the feared event may concern the immediate meaning of a bodily sensation. In social anxiety, it may concern another person's appraisal, an uncertain social consequence or the belief that anxiety is visibly unacceptable. Simply remaining in a situation is not an adequate experimental description: someone may remain while attributing safety to a precaution, directing attention inward or interpreting an ambiguous response as rejection.

Experimental evidence tests this functional argument. Paul Salkovskis and colleagues manipulated safety-seeking behavior during exposure in panic disorder with agoraphobia. The study supports examining what the person does during exposure rather than treating exposure duration as its only relevant feature. It does not imply that every protective behavior is unnecessary, nor that an effect in a short task demonstrates the complete mechanism of long-term recovery. The prediction being tested and the person's explanation of the outcome remain important.^[ref]

For social anxiety, Freda McManus and colleagues first assessed safety behaviors by interview and then manipulated safety behaviors and self-focus experimentally. Greater safety behavior use characterized high social anxiety, and the manipulation supported adverse effects of the combined maintaining processes. The interview association alone would allow reverse causation; the experimental contrast provides stronger evidence of an immediate influence. Because attention and behavior were manipulated together, it is less decisive about their independent effects. Brief arranged interactions also cannot establish the magnitude of lasting treatment benefit.^[ref]

Both treatments can begin with a shared clinical formulation, specified predictions and behavioral experiments. In panic, interoceptive exposure can make relevant sensations available for testing while changing the safety behavior that would otherwise be credited with preventing catastrophe. The learning question concerns the predicted consequence and the meaning of the sensation, not merely whether anxiety eventually declines. In social anxiety, experiments can redirect attention to the interaction and test predicted evaluations while reducing relevant safety behaviors. The content is matched to social interpretation rather than transferred mechanically from a bodily-sensation exercise.

Video feedback is particularly pertinent when a person treats a negative self-image as an accurate external view. Preparing a clear prediction about appearance and then comparing it with the recording creates a more interpretable test than simply asking the person to watch themselves. A recording is still a limited sample, and the person's selective interpretation of it needs examination. Social experiments may also test how others respond to ordinary imperfections rather than making perfect performance the criterion for safety. These principles follow from the proposed maintaining process and should remain open to outcome evaluation.

Treatment comparisons provide evidence at a broader level. David M. Clark and colleagues' panic trial compared cognitive therapy, applied relaxation and imipramine, with self-exposure homework shared across conditions. The cognitive therapy findings support the package, but common homework means that differences cannot be attributed to exposure being present in one arm and absent in all others. Therapist effects, credibility, dose and follow-up are also relevant when interpreting comparative outcomes.^[ref]

In social phobia, David M. Clark and colleagues randomized participants to cognitive therapy, exposure with applied relaxation or a waiting condition. Cognitive therapy showed a stronger outcome than the exposure/relaxation package on the principal comparisons. This is evidence against treating all interventions that contain exposure as interchangeable. It does not establish that a single feature, such as video feedback, explains the difference, because the packages differ on multiple dimensions. A dismantling study or a carefully specified mediation design would be needed for that narrower causal claim.^[ref]

Treatment planning also needs the person's goals, comorbidity and constraints. A ritualized breathing strategy, inward monitoring or avoidance can serve different functions in different cases; its name does not determine its effect. Outcomes should include functioning and flexibility alongside symptom scores, and tests of maintenance should examine whether feared situations can be approached without recreating the same safety rules. This is why a transdiagnostic process can justify shared principles without requiring a single standardized sequence for everyone.

The shared targets are threatening interpretation, self-confirming attention and safety behavior that obstructs updating; the specific targets depend on whether bodily catastrophe or social evaluation organizes the difficulty. Evidence for package efficacy and evidence for a proposed mechanism answer different questions. Effective comparison requires both, with the limits of the experimental manipulation kept distinct from those of the clinical trial.
