Severity rating scales for ciguatera fish poisoning

W. R. Lange. Severity rating scales for ciguatera fish poisoning. Toxicon 31, 777–781, 1993.—Severity of ciguatera fish poisoning is often quite variable. Two symptom check list rating scales were developed for quantifying illness severity and for selectively monitoring response to therapy in patients with chronic toxicity. Content validity was ascertained, and internal consistency reliability was demonstrated by means of the Cronbach alpha correlation coefficient (alpha = 0.9475). It was concluded that these instruments were valid and reliable, and that they conveniently and accurately recorded illness severity and treatment efficacy. They should prove useful in clinical settings and epidemiologic investigations.
