The Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) has not been explicitly tested on an adolescent population. In this study, the German version of the HGSHS:A was administered to 99 German adolescents aged 15 to 19. In contrast to other studies, the gender distribution was relatively balanced: 57% female and 43% male. Results were comparable to 14 earlier studies with regard to distribution, mean, and standard deviation. Some peculiarities in contrast to the 14 previous studies are pointed out. It is concluded that the HGSHS:A can be used as a valid and reliable instrument to measure hypnotic suggestibility in adolescent samples.
Ninety-two high school and 8 secondary school students, aged between 15 and 19 years, were tested for intelligence and for hypnotic susceptibility. No correlations could be observed for the overall sample unselected by sex because the negative correlations for male participants canceled out the positive correlations for the female subsample. These are significant for the total value of intelligence (r = .288) and highly significant for the subcategory verbal intelligence (r = .348), yet nonsignificant for the subcategories numerical intelligence and figural intelligence. Females seem to be more able to imaginatively process semantic contents induced verbally. They also seem to have a higher task motivation than males—at least during adolescence.
