Abstract
We have presented in our previous study the possibility of classifying technostress syndrome into 5 types based on clinical observation. In the present study, we investigated the possibility of classifying the syndrome based on Hayashi's quantification theory. In quantification III, objects could be devided into two types by factor I whether they exhibited somatic symptoms or mental symptoms. And objects also could be devided into two types by factor II according to clinical courses. Then we could see 4 types of internal structure by quantification III. In quantification II, we could divide 5 clinical subtypes (anxiety type, techno-centered type, somaticpersonality type, passive-adaptive type, immature type) into 5 different groups by evaluating 3 factors. As to classification, personality trait is the most attributable factor and cardiovascular symptoms and anxiety are also important. Consequently, the technostress syndrome is classified into the following types which are somewhat proper statistically. Each with its own characteristics as described below. 1. Anxiety type. This type is closely related to persons with typus melancholicus, anxiety disorder. Its response to drugs and prognosis are favorable. 2. Techno-centered type. This type is closely related to males with a long professional career. The personality trait is closely related to cluster A (DSM-III-R), suppressive symptoms mood disorders. 3. Somatic-personality type. Its personality trait is closely related to cluster C (DSM-III-R). This type is often diagnosed as somatoform disorder or psychosomatic disease. Its symptoms tend to be persistent. 4. Passive-adaptive type. Its personality trait is closely related to cluster C (DSM-III-R). This clinical course often becomes chronic but its social adjustment is good. In the present study, it is difficult to distinguish this type from other types. 5. Immature type. This type is closely related to females with a short professional career. From these findings, I came to the conclusion that it is important to evaluate technostress symdrome totally from the point of its longitudinal course, for example response to treatment, prognosis, as well as to pay attention to the onset situation.
