Introduction.  The Clinical Global Impression of Change (CGIC) measures have high utility in clinical practice. However, it is unknown whether the CGIC is valued for assessing premature ejaculation (PE) symptoms and/or the relationship between CGIC and other validated PE patient-reported measures.

Aim.  The study aims to assess the validity of the patient-reported CGIC measure in men with PE and to examine the relationship between CGIC ratings and assessments of control, satisfaction, personal distress, and interpersonal difficulty.

Methods.  Data from a randomized, double-blind, 24-week phase 3 trial in 1,162 men with PE who received dapoxetine (30 mg or 60 mg) or placebo on demand provided the basis for the analysis. Patients were ≥18 years, in a stable monogamous relationship for ≥6 months, met the Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition-Text Revision criteria for PE for ≥6 months, and had an intravaginal ejaculatory latency time (IELT) ≤2 minutes in ≥75% of intercourse episodes.

Main Outcome Measures.  The CGIC asked patients to rate improvement or worsening of their PE compared with the start of the study using a 7-point response scale; other patient-reported measures were control over ejaculation, satisfaction with sexual intercourse, interpersonal difficulty, and personal distress related to ejaculation. Stopwatch-measured IELT was recorded. Associations between CGIC and change in other measures at study end point were assessed.

Results.  The magnitude of IELT increased for each category of improvement on the CGIC: 1.63, 4.03, and 7.15 minutes for slightly better, better, and much better, respectively. Higher CGIC ratings were correlated with greater improvement in control (r = 0.73), satisfaction (r = 0.62), greater reduction in distress (r = −0.52), and interpersonal difficulty (r = −0.39). Total variance accounted for was 57.4%: control (48.7%), satisfaction (4.5%), IELT (2.8%), and distress (1.15%).

Conclusions.  The analyses support the validity of the CGIC measure in men with PE. The CGIC can provide clinicians in practice with a valid and brief outcome assessment of their patient's condition.
