title: [A study of relationships among solvent inhalation, personality and expectancy; especially on affinity to hallucination, sensation seeking and neurotic tendency].
abstract: 94 delinquents in two homes for resocialization were surveyed to elucidate the relationship among the status of volatile solvent inhalation, expectancy and personality. The subjects were classified into solvent-inhalation group and non-solvent-inhalation group, and the former was divided into solvent dependence group and abuse group according to DSM-III-R. Each group was given personality tests; general health questionnaire (GHQ), sensation seeking scale (SSS), the vividness of visual imagery (VVIQ), test of visual imagery control (TVIC) and Yatabe-Guilford test (YG). In addition we investigated expectancy and mental symptoms caused by inhalation in it. The results are summarized as follows; 1. Inhalation group scored higher on SSS than non-inhalation group. 2. Compared with abuse group, dependence group presented with 1) higher GHQ score meaning neurotic tendency; 2) higher TVIC score meaning imagery-control-ability; 3) a higher incidence of day-dream and hallucination, especially egosyntonic type; 4) higher expectancy of "enhancement of positive affection", "reduction of negative affection" and "hallucination seeking"; 5) lower expectancy of "association with friends". 3. Higher scored inhalers on TVIC showed visual hallucinations, especially egosyntonic type more frequently than lower ones. 4. Significant correlations were recognized between GHQ score and expectancy of "reduction of negative affection", and between lack of objectiveness score of YG subscale and "hallucination seeking" expectancy. These results suggested that 1) beginning of inhalation is associated with sensation seeking trait, 2) progression to solvent dependence is correlated with three expectancies, i.e., seeking egosyntonic hallucinations paralleling high imagery-control-ability and subjectivity, reducing negative affection paralleling neurotic tendency, and enhancing positive affection. According to the findings, indulgence to drug induced positive imagery led delinquents into splitting of personality. In their treatment we need to help them to integrate high imagery ability and sensation seeking for recovery.
