Hypnotic inductions with deaf and hearing subjects--an initial comparison: a brief communication

Area of Science:

• Psychology
• Hypnotherapy Research
• Sensory Impairment Studies

Background:

• Hypnotic suggestibility research has primarily focused on hearing populations.
• Understanding potential differences in hypnotic experiences for deaf individuals is crucial for inclusive therapeutic practices.

Purpose of the Study:

• To compare hypnotic suggestibility and related experiences between deaf and hearing volunteers.
• To investigate differences in objective and subjective hypnotic measures, including rapport, resistance, and trance experience.

Main Methods:

• A 2x2 ANOVA design was used to compare 17 deaf and 18 hearing participants.
• Participants were assessed using the Stanford Hypnotic Clinical Scale (SHCS) and the Indirect Suggestion Scale (ISS).
• Dependent measures included objective and self-report scores, rapport, resistance, and subjective trance ratings.

Main Results:

• No significant differences were found in objective hypnotic suggestibility scores (SHCS behavioral items) between deaf and hearing groups or between direct/indirect induction methods.
• Deaf participants reported significantly higher resistance to the hypnotist compared to hearing participants.
• No significant differences were observed in self-report scores, rapport, or overall subjective trance ratings.

Conclusions:

• While hypnotic suggestibility may not differ significantly based on hearing status, resistance levels do.
• Communication modality or the hearing status of the hypnotist may influence resistance in deaf individuals during hypnosis.
• Further research is needed to explore the implications of these findings for therapeutic applications of hypnosis with deaf populations.
