EDITS: development of questionnaires for evaluating satisfaction with treatments for erectile dysfunction

Area of Science:

• Urology
• Psychometrics
• Sexual Medicine

Background:

• Treatment satisfaction is a subjective evaluation distinct from treatment efficacy.
• Assessing patient and partner satisfaction is crucial for understanding treatment outcomes in erectile dysfunction (ED).

Purpose of the Study:

• To develop and validate the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) with distinct Patient and Partner versions.
• To create a psychometrically sound instrument for measuring satisfaction with medical treatments for ED.

Main Methods:

• Generated 29 patient and 20 partner items for treatment satisfaction assessment.
• Assessed test-retest reliability, content validity, and internal consistency across two independent couple samples.
• Selected items based on response range, reliability, content validity panel ratings, and subject-partner correlation.

Main Results:

• The final Patient EDITS comprises 11 items and the Partner EDITS comprises 5 items.
• Both versions demonstrated excellent psychometric properties: internal consistencies of 0.90 (Patient) and 0.76 (Partner).
• High test-retest reliability was confirmed: 0.98 for Patient EDITS and 0.83 for Partner EDITS.

Conclusions:

• The EDITS (Patient and Partner versions) is a reliable and valid tool for assessing satisfaction with ED treatments.
• Established psychometric properties support its use in clinical practice and research.
• The EDITS can be utilized to explore the influence of patient and partner satisfaction on treatment adherence and continuation.
