AB  - BACKGROUND: The somatosensory amplification scale (SSAS) is a 10-item self-report 
      instrument designed to assess a tendency to experience normal somatic and 
      visceral sensations as intense, noxious, and disturbing. OBJECTIVES: The present 
      study investigated the reliability and validity of the SSAS, developed by Barsky 
      et al. (1988), in the Iranian population. MATERIALS AND METHODS: The study was 
      carried out on 240 patients with functional gastrointestinal disorders and 30 
      healthy persons selected by convenience sampling from 2013 to 2014. The patients 
      completed the SSAS, the somatization subscale of the symptom checklist-90-revised 
      (SCL-90-R som), and the modified somatic perception questionnaire (MSPQ), whereas 
      the healthy persons completed just the SSAS. RESULTS: Exploratory factor analysis 
      indicated that the one-factor solution, accounting for 29.42% of the variance, 
      explained that the SSAS items were represented by one global dimension. The SSAS 
      had acceptable internal consistency (alpha = 0.78) and good test-retest reliability 
      (r = 0.80). The item-to-scale correlations varied from 0.17 to 0.55. Item 2 had 
      the lowest item-total score correlation (r = 0.17), and the alpha coefficient for the 
      SSAS exceeded when this item was deleted. The convergent validity of the SSAS 
      with somatization was shown with a significant correlation between the SSAS, 
      SCL-90-R som (r = 0.36), and MSPQ scores (r = 0.52). Discriminant validity 
      analysis showed no significant difference in the SSAS between the patient and 
      control groups (P > 0.05) and non-specificity of the SSAS for patients. 
      CONCLUSIONS: In sum, the SSAS has acceptable reliability and validity for the 
      Iranian population and the scale measures the same the original scale, namely 
      somatosensory amplification.
