The effects of self-hypnosis for children with cystic fibrosis: a pilot study.

This pilot study assessed the effects of self-hypnosis on psychological and physiological functioning of children ages 7 to 18 with Cystic Fibrosis (N = 12). The study used a pre- and posttest design, repeated measures, and control group. Control and experimental groups were matched for age and clinical severity. The experimental group demonstrated significant changes in locus of control, health locus of control, and self-concept. State anxiety scores did not differ significantly, but changes in trait anxiety distinguished the experimental group from the control group. The experimental group also demonstrated significant increase in peak expiratory flow rates using an air flow meter immediately after self-hypnosis when compared to the control group. Generalizability of the results is discussed in terms of the small sample size. Recommendations are offered for future studies with larger samples and variations in procedure.
