2. Development of the “shitsu-taikan-sho” scale ＜日本語＞
“Shitsu-taikan-sho” refers to condition of having difficulty in experiencing bodily feelings. This concept was firstly proposed by Dr. Yujiro Ikemi in 1979 as conditions commonly observed in patients with psychosomatic diseases. To date, however, there is no questionnaire to measure shitsu-tailan-sho. Therefore, based on the previous studies including ours, we developed a shitsu-taikan-sho scale (bodily awareness checklist)(ref. 1).
How we developed it: Four hundred and forty one undergraduate students completed the 44-item draft shitsu-taikan-sho scale. Two hundred and eighteen of them completed the draft scale and The Toronto Alexithymia Scale 20 item version (TAS-20). Two hundred twenty three of them completed the draft scale twice at two-week interval. Exploratory factor analyses resulted in a 23-item instrument (The shitsu-taikan-sho scale) with an adequate oblique 3-factor structure: (1) Difficulty of identifying bodily feeling subscale (nine questions), (2) Over-adaptation subscale (six questions), and (3) Lack of health management based bodily feeling subscale (eight questions). Results exhibited adequate internal consistency and test-retest reliability of total score and subscales of the shitsu-taikan-sho scale. Correlations with TAS-20 suggested acceptable construct validity for the shitsu-taikan-sho scale.
The shitsu-taikan-sho scale is the first instrument assessing the shitsu-taikan-sho.
Shitsu-taikan-sho scale enables us to conduct quantitative evaluation of shitsu-taikan-sho tendency and to conduct researches on how shitsu-taikan-sho contributes to the development of stress-related, psychosomatic diseases. If you are interested in this scale, please email me. (2012, July 28th)
