The relation betweenChildhood Abuse, Altered States of Consciousness andHypnotizability

Although the score ofhypnotizability of those who have experienced childhood abuse was greater than that of control groups（Nash, et al., 1983, it was currentlyreported that trauma has nocorrelation with hypnotizability（Putnam, et al., 1995.Altered States of Consciousness（ASC）are mental sates different from the normal awake conscious state（Ludwig, 1960）. A hypnotic state has been cited in literature as one of the ASC（Tart, 1990）, however, there hasnot been enough evidence to support this notion（Kallio & Revonsuo, 2003）.Furthermore, a 4-D model was suggested as a framework for classifying symptoms of posttraumatic stress（ex., childhood abuse）into normal waking consciousness（NWC）versus trauma-related altered states of consciousness（TRASC）（Frewen & Lanius, 2014）.Although, we can’t findstudies that have measured these three variables at the same time and examined their relation. Then, in this study, the relation between childhood abuse, ASC, and hypnotizability was examined.The university students were required to answer the Child Abuse and Trauma Scale（Sanders & Giolas, 1991; Sanders & Becker-Lauren, 1995）to measure the childhood abuse, the ASC test（Saito, 1981）to measure ASC, and Harvard Group Scale of Hypnotic Susceptibility（HGSHS; Shor and Orne, 1962）to measure hypnotizability. Consequently, each of their scores were yielded. This data of hypnotizabilty used in this study overlappedwith Nakatani, et al.（2018, 2019）and Fukui et al.（2017, 2018）. Our study has yielded more data in this field of research.
