Summary

Clomipramine effectively improved subthreshold mood symptoms like irritability and anxiety in healthy volunteers without diagnosed psychopathology. This suggests psychopharmacological agents can address subclinical complaints.

Area of Science:

  • Psychopharmacology
  • Clinical Psychology

Background:

  • Subthreshold symptoms can impact well-being despite absence of diagnosed psychopathology.
  • Investigating interventions for these subclinical complaints is clinically relevant.

Purpose of the Study:

  • To evaluate the efficacy of clomipramine in improving subthreshold non-specific symptoms in individuals without diagnosed psychopathology.
  • To assess clomipramine's effects on mood, irritability, and anxiety in a healthy volunteer population.

Main Methods:

  • Double-blind, cross-over controlled trial involving clomipramine (10-40 mg/day) and propanthelinet (active placebo).
  • Study duration was 5 weeks, conducted in nine normal volunteers.
  • Participants were screened to exclude established psychopathology using psychiatric interviews and standardized questionnaires.

Main Results:

  • Clomipramine demonstrated significant improvements in mood assessments compared to placebo.
  • Specifically, decreased irritability and anxiety were consistently reported by both subjects and observers.
  • Improvements were noted despite the small sample size and low initial symptom levels.

Conclusions:

  • Psychopharmacological agents like clomipramine may be effective in improving subclinical mood complaints.
  • The findings raise questions regarding the mechanisms of action for such treatments.
  • This study highlights potential implications for managing subclinical psychological distress.
