This long-term follow-up recruited participants from an earlier IEI-EMF provocation trial and re-administered the same questionnaire by telephone. Of 70 completers (35 IEI-EMF patients and 35 referents), 62.9% of patients reported recovery after an average of 1.8 years, with most recoveries described as spontaneous.…
Exposure Perception and Symptom Reporting in Idiopathic Environmental Intolerance Attributed to Electromagnetic Fields Using a Co-Designed Provocation Test

This co-designed provocation study in IEI-EMF volunteers evaluated whether perceived exposure and symptom reporting tracked actual EMF exposure under double-blind conditions. The abstract reports no consistent alignment between perceived exposure certainty or symptoms and true exposure status at the group level, with…
Chicken or egg? Attribution hypothesis and nocebo hypothesis to explain somatization associated to perceived RF-EMF exposure

This longitudinal cohort study examined the temporal relationship between somatization and perceived RF-EMF exposure, comparing the attribution hypothesis with the nocebo hypothesis. Using AMIGO questionnaire data from 2011 and 2015, regression analyses suggested the attribution hypothesis more often explained…

This paper re-analyzes data from two prior double-blind provocation studies involving RF base station signals and sham exposures. Symptoms and reduced well-being were more strongly associated with participants' belief that the base station was "on" than with the exposure condition itself. The authors conclude that a…
Does precautionary information about electromagnetic fields trigger nocebo responses? An experimental risk communication study.

This experimental study tested whether providing precautionary information about EMF from WLAN devices increases symptom reporting during an alleged exposure situation. In a sham-exposure design (N=137), participants received either basic information about current WLAN exposure limits or additional precautionary…
