Behavior therapy, supportive psychotherapy, imipramine, and phobias

Area of Science:

• Psychiatry
• Clinical Psychology
• Pharmacology

Background:

• Phobias represent a significant mental health challenge.
• Effective treatment strategies for diverse phobia subtypes are crucial.

Purpose of the Study:

• To compare the efficacy of behavior therapy and supportive psychotherapy combined with imipramine hydrochloride versus placebo.
• To evaluate treatment outcomes across different phobia classifications (agoraphobic, mixed, simple).

Main Methods:

• A controlled outcome study involving 111 adult patients with phobias.
• Treatment regimens included behavior therapy with imipramine hydrochloride, behavior therapy with placebo, and supportive psychotherapy with imipramine hydrochloride.
• Patients were assessed for global improvement and specific phobia subtypes.

Main Results:

• High rates of global improvement (70-86%) were observed across all treatment groups.
• Imipramine hydrochloride demonstrated significant superiority over placebo for agoraphobic and mixed phobics experiencing panic attacks.
• Behavior therapy and supportive psychotherapy yielded similar high improvement rates.
• Simple phobic patients showed high improvement regardless of treatment, with no significant drug or therapy differences.
• Long-term follow-up (1 year) showed sustained gains in 83% of improved patients, with 17% relapse.
• Eighteen percent of imipramine hydrochloride recipients experienced stimulant side effects.

Conclusions:

• Imipramine hydrochloride is effective for panic-associated phobias when combined with behavior therapy.
• Behavior therapy and supportive psychotherapy show comparable efficacy.
• Long-term maintenance of gains is common, and symptom substitution was not observed.
• Careful monitoring for stimulant side effects is warranted with imipramine hydrochloride.
