Development and Validation of a Turkish Hypnotic Suggestibility Scale

To construct a scale for testing hypnotic suggestibility for Turkish-speaking adults that may be quick and convenient, and to test its reliability and validity.

The study was conducted at the hypnotherapy outpatient clinics of Atatürk University Acupuncture and Complementary Medicine Application and Research Centre. Erzurum, Turkey, from June to August 2017, and comprised aged 18-60 years. As the first step in the preparation of the scale, a panel of 15 experts was founded. The draft was pilot-tested. Incomprehensible suggestion templates in the pilot study were abolished, and the templates were reduced to four which were put to test as the Tastan Suggestibility Scale. Stanford Hypnotic Clinic Scale was also used on the same subjects, and the results were analysed using SPSS. .

Of the 61 subjects, 38(62.3%) were females and 23(37.7%) were males. The overall mean age was 34.21±9.9 years. Cronbach alpha internal reliability coefficient of the scale was calculated to be 0.53. Correlation between the Tastan Suggestibility Scale and Stanford Hypnotic Clinic Scale total scores was high (p<0.001). Mean duration of the application of the scale was 5.0±1.2 minutes.

Tastan Suggestibility Scale was found to be a new, reliable, and rapidly applicable scale.
