Methods An adapted version of the SOMS-2 was filled in by persons attending a PC unit. All medically unexplained symptoms were further ascertained in a clinical interview and by contacting the patient s physicians and examining medical records attaining a final clinical symptom evaluation FCSE . An interview yielded the diagnosis of Clinical Somatization CS and the diagnosis of current depressive and anxiety disorders. Results From the eligible subjects 167 agreed to participate and 34.1 of them were diagnosed with somatization. The correlation between the number of self-reported and FCSE symptoms was 0.63. After excluding symptoms with low frequency low discriminative power and not correlated with the overall scale 29 were retained in the final version. A cut-off of 4 symptoms gave a sensitivity of 86.0 and a specificity of 95.5 on the FCSE and 56.1 and 93.6 at selfreport. Stability in the number of symptoms after 6 months was good k 0.57 .
