SIEDY Scale 3, a new instrument to detect psychological component in subjects with erectile dysfunction - Abstract

Introduction: We previously developed and validated a structured interview (SIEDY) dealing with the organic (Scale 1), relational (Scale 2), and psychological (Scale 3) components of erectile dysfunction (ED).

Aim: To identify a pathological threshold for SIEDY Scale 3 and to analyze Scale 3 score with biological and psychological correlates in subjects with sexual dysfunction.

Method: A pathological threshold of SIEDY Scale 3 score in predicting subjects with a medical history of psychopathology and using psychiatric drugs was identified through receiver operating characteristic (ROC) curve analysis in a sample of 484 patients (Sample A).

Main Outcome Measure: Sensitivity and specificity, along with possible interactions with biological and psychological (Middlesex Hospital Questionnaire, MHQ-score) correlates were verified in a further sample of 1,275 patients (Sample B).

Results: In sample A, 39 (8%) and 60 (12.4%) subjects reported a positive medical history for psychiatric disturbances or for the use of psychotropic medication, respectively. The association with both conditions was present in 28 (5.8%) subjects. ROC curve showed that SIEDY Scale 3 score predicts psychopathology with an accuracy of 69.5 ± 5.9% (P < 0.002), when a threshold of 3 was chosen. When the same threshold was applied in Sample B, it identified a higher ranking in MHQ-A (free-floating anxiety), MHQ-S (somatized anxiety) and MHQ-D (depressive symptoms) subscales, even after adjustment for age and Σ-MHQ (a broader index of general psychopathology). In the same sample, we also confirmed that pathological Scale 3 score was related to a higher risk of psychopathology at medical history or to the use of psychotropic drugs as well as with risky lifestyle behaviors, including smoking and alcohol abuse, and elevated BMI.

Conclusions: SIEDY represents an easy tool for the identification of patients with a relevant intra-psychic component who should be considered for psychological/psychiatric treatment.
