Current and Past Project
  • The autogenic training (AT) is a psychotherapy that has been described as a non-drug therapy in "The Treatment and Treatment Guidelines for Sleep Disorders" (Second Edition). Gradually repeat self-intention, create a relaxed state, and promote sleep by releasing mind and body tension. Thus, although it is described that it is effective for insomnia, there are few studies that demonstrated its mechanism of effect expression from the physiological aspect. It is known that autonomic nervous function differs between daytime and nighttime, and it differs greatly in the first half and the second half while sleeping.
    In this study, we aim to clarify how AT changes nighttime autonomic nervous activity and promotes sleep using 24-hour Holter ECG.

The aim of this study was to identify which aspects of the burden of chronic pain patients are associated with Self/illness separation (SIS), an indicator of the magnitude of suffering. We also examined the effectiveness of PRISM for evaluating changes in the relationships between patients and their medical care and significant others due to our inpatient treatment. METHODS: Seventy-two patients with chronic pain who were outpatients or admitted to the Department of Psychosomatic Medicine completed PRISM, depression and anxiety scales, and three types of pain-related self-assessment questionnaires (Brief Pain Inventory, Short-form McGill Pain Questionnaire, and Pain Catastrophizing Scale). Outpatients were queried at the time of outpatient visits and inpatients at the time of admission. In addition to PRISM disks related to illness, we asked each patient to place disks related to things important to them and their medical care. Of the inpatients, 31 did PRISM at the time of discharge. Among the reported important factors, which significant other was placed at the time of admission and discharge was evaluated. The distances of self/medical care separation (SMcS) and self/significant others separation (SSoS) were measured. RESULTS: Of the 21 scales measured, 10 showed a significant correlation with SIS. Factor analysis of these 10 scales extracted three factors, Life interferences, Negative affects, and Pain intensity. The SMcS and SSoS distances were shorter at discharge than at admission. CONCLUSIONS: PRISM for patients with chronic pain is an integrated evaluation method that reflects three aspects of pain. By adding medical care and significant others to the usual method of placing only illness on the sheet it became possible to assess changes in the quality of interpersonal relationships..

Methods: The English SCL-90-R was translated to Japanese and the Japanese version confirmed by back-translation. To determine the factor validity and internal consistency of the nine primary subscales, 460 people from the community completed SCL-90-R(J). Test-retest reliability was examined for 104 outpatients and 124 healthy undergraduate students. The convergent-discriminant validity was determined for 80 inpatients who replied to both SCL-90-R(J) and the Minnesota Multiphasic Personality Inventory (MMPI). Results: The correlation coefficients between the nine primary subscales and items were .26 to .78. Cronbach's alpha coefficients were from .76 (Phobic Anxiety) to .86 (Interpersonal Sensitivity). Pearson's correlation coefficients between test-retest scores were from .81 (Psychoticism) to .90 (Somatization) for the outpatients and were from .64 (Phobic Anxiety) to .78 (Paranoid Ideation) for the students. Each of the nine primary subscales correlated well with their corresponding constructs in the MMPI. Conclusion: We confirmed the validity and reliability of SCL-90-R(J) for the measurement of individual distress. The nine primary subscales were consistent with the items of the original English version. © 2008 Tomioka et al

1. 富岡 光直, 須藤 信行, Image-exposure during autogenic training alleviates physical symptoms in patients with anxiety disorder., The 17th Asian Congress on Psychosomatic Medicine, 2016.08, Objective: Patients with anxiety disorder often show not only emotional symptoms but also physical symptoms following exposure to external stimuli. In vivo exposure to such external stimuli has been established as a useful treatment option; however, whether image-exposure exerts positive effects on anxiety-induced physical symptoms is inconclusive.
Methods: We treated two patients with anxiety disorder using image-exposure therapy. After the introduction of autogenic training (AT), patients were asked to imagine anxiety-evoking scenes and retain the scenes in their mind for 1 min; they then performed a 30 second AT. They did the image-exposure three times per visit.
Results: At the first trial, the patients complained about anxiety-related physical symptoms such as chest oppression, congested feeling, thirst, and palpitations. Their physical symptoms and anxiety levels in daily life decreased after repeated image-exposure trials.
Conclusion: Image exposure during AT was effective for reducing anxiety-related physical symptoms in patients with anxiety disorder..
