「内田クレペリン精神検査（連続加算）」における生体ストレス指標と気分の継時的変化

Alteration of salivary α-amylase, heart rate and mood during the Uchida-Kraepelin Psychodiagnostic Test (consecutive addition)

要旨：「内田クレペリン精神検査（連続加算）」（以下，U-KT）が精神的負荷か否か人への影響の検討を目的に，女性24名，平均年齢21歳を対象に前後20分間の安静を設け計75分間実施した．この間，唾液αアミラーゼ活性（以下，Amy）と心拍の継時的測定，POMSによる気分の変化とフロー質問紙による主観的困難度を調査した結果，個人差もあるが前安静より後安静のAmy・心拍・POMSの「混乱」，「活気」が有意に低値を示し，作業中のAmyは作業前半の値は高いが，後半は前半および前安静より低値となり作業量の多い対象者ほどこの傾向が著明であった．U-KTは一概に精神的負荷とならず，それ自体がストレスを軽減し気分を改善する可能性が示唆された．

　The mental load effect of the “Uchida-Kraepelin Psychodiagnostic Test (KT)” on 24 healthy women, average age 21 years old was examined. The markers of stress activation in the subjects were measured by monitoring the alteration of salivary alpha amylase (Amy) and heart rate (H) for 75 minutes during KT, as well as during 20-minute rests before and after KT. The patients' subjective feeling and degree of difficulty using the KT were also investigated using the Profile of Mood States (POMS) questionnaire before and after the KT, and Flow questionnaire, respectively. As a result, Amy, H and “confusion”, and “vigor” of POMS during rest after the KT showed significantly lower scores than those at rest before KT. In addition, the values of those markers during the first half of the tasks tended to be high, but those in the later half were low. This trend is even more marked in subjects who made more effort. According to the above results KT may not be a mental burden in general, and may reduce stress and improve mood.
