Assessing the onset of antidepressant-induced sexual dysfunction using interactive voice response technology

Area of Science:

• Pharmacology
• Psychiatry
• Medical Technology

Background:

• Sexual dysfunction is a common, underreported symptom of major depression and a side effect of antidepressant medications.
• Validated tools like the Changes in Sexual Functioning Questionnaire (CSFQ) exist but are often underutilized in clinical settings.

Purpose of the Study:

• To evaluate the validity of using interactive voice response (IVR) technology for collecting data on sexual dysfunction via the CSFQ.
• To compare IVR-based CSFQ assessments with traditional paper-and-pencil methods.

Main Methods:

• 99 healthy male volunteers received paroxetine, CP-448,187, or placebo for 3 weeks.
• Participants completed both paper-and-pencil and IVR versions of the 14-item CSFQ at baseline and multiple follow-up points.
• IVR assessments were also conducted at home between office visits to capture earlier symptom onset.

Main Results:

• A high overall correlation (r = 0.96) was observed between paper and IVR CSFQ total scores.
• Both methods detected significant sexual dysfunction by day 8, with IVR identifying onset as early as day 4.
• IVR data showed antidepressant-related sexual dysfunction affected all CSFQ domains.

Conclusions:

• IVR assessment of sexual dysfunction using the CSFQ is highly correlated with paper-and-pencil methods.
• IVR offers a valid and user-friendly alternative for systematically collecting data on antidepressant treatment side effects.
• The frequent assessments enabled by IVR allow for more precise evaluation of sexual dysfunction symptom onset.
