Development of a structured interview for the modified version of the Beth Israel Hospital psychosomatic questionnaire for alexithymia
For Japanese young adults, the m-SIBIQ is a reliable and valid instrument for overcoming weaknesses of the self-reported procedures by bringing to light the alexithymia construct and principal dimensions

Neural correlates of body comparison and weight estimation in weight-recovered anorexia nervosa
BACKGROUND: The neural mechanisms underlying body dissatisfaction and emotional problems evoked by social comparisons in patients with anorexia nervosa (AN) are currently unclear. Here, we elucidate patterns of brain activation among recovered patients with AN (recAN) during body comparison and weight estimation with functional magnetic resonance imaging (fMRI). METHODS: We used fMRI to examine 12 patients with recAN and 13 healthy controls while…

Psychometric properties of the eating disorder examination-questionnaire in Japanese adolescents
BACKGROUND: Although the Eating Disorder Examination Questionnaire version 6.0 (EDE-Q) is one of the most widely used questionnaires for eating disorders in Western countries, no research has addressed the psychometric properties of the EDE-Q in a Japanese sample. METHODS: We explored the factor structure of the EDE-Q and examined the internal consistency of the derived scales for Japanese participants (Study I), the convergent validity with othe…
Predictors of successful long-term weight loss maintenance
BACKGROUND: Weight regain is a common problem following weight loss intervention, with most people who seek treatment for obesity able to lose weight, but few able to sustain the changes in behavior required to prevent subsequent weight regain. The identification of factors that predict which patients will successfully maintain weight loss or who are at risk of weight regain after weight loss intervention is necessary to improve the current weigh…
Factors associated with caregiving burden and mental health conditions in caregivers of patients with anorexia nervosa in Japan
BACKGROUND: There are no studies about the caregiving burdens in families of patients with eating disorders in Japan, and only limited studies on the role of caregivers' stress coping, social support, and mental health. This study examines caregiving burdens, mental health conditions, and associated factors in caregivers of anorexia nervosa (AN) patients in Japan. METHODS: Seventy-nine principal caregivers (70 mothers, 5 fathers, 3 spouses and 1 …
The outcome of treatment for anorexia nervosa inpatients who required urgent hospitalization
BACKGROUND: This study was done to determine which psychosocial factors are related to the urgent hospitalization of anorexia nervosa patients (AN) due to extremely poor physical condition and to evaluate their outcome after inpatient treatment. METHODS: 133 hospitalized AN patients were classified into an urgent hospitalization (n = 24) or a planned hospitalization (n = 109) group. Multiple regression analysis was done of clinical features, body…
Neuroimaging studies of alexithymia
Alexithymia refers to difficulty in identifying and expressing one's emotions, and it is related to disturbed emotional regulation. It was originally proposed as a personality trait that plays a central role in psychosomatic diseases. This review of neuroimaging studies on alexithymia suggests that alexithymia is associated with reduced neural responses to emotional stimuli from the external environment, as well as with reduced activity during im…
Diurnal variation of tension-type headache intensity and exacerbation
BACKGROUNDS: Tension-type headache is a common psychosomatic disease. However, diurnal variation of headache is yet to be clarified, perhaps due to the lack of an appropriate method to investigate it. Like other painful diseases, it would be helpful to know if there is diurnal variation in tension-type headaches, both for managing headaches and understanding their pathophysiology. The aim of this study was to determine if there is diurnal variati…
The reliability and validity of the Japanese version of the Levels of Emotional Awareness Scale (Leas-J)
BACKGROUND: The Levels of Emotional Awareness Scale (LEAS) was developed to assess five levels of emotional awareness: bodily sensations, action tendencies, single emotions, blends of emotion, and combinations of blends. It is a paper and pencil performance questionnaire that presents 20 emotion-evoking scenes. We developed a Japanese version of the LEAS (LEAS-J), and its reliability and validity were examined. METHODS: The LEAS-J level was indep…
Does sleep aggravate tension-type headache
BACKGROUND: Both insufficient sleep and oversleeping have been reported as precipitating and aggravating factors of tension-type headache (TTH). However, previous studies relied on recalled self-reports, and the relationship has not been confirmed prospectively and objectively in a daily life situation. Recently, ecological momentary assessment (EMA) using electronic diaries, i.e., computerized EMA, is used to record subjective symptoms with the …
Validity issues in the assessment of alexithymia related to the developmental stages of emotional cognition and language
OBJECTIVE: We examined developmental aspects of the emotional awareness of adolescents by evaluating their responses to a self-reported questionnaire based on the Toronto Alexithymia Scale-20 (TAS-20). METHODS: The items of the TAS-20 were modified to make them more understandable by adolescents, and nine new items related to a limited capacity for imagination were added. The Japanese Linguistic Ability Test and the multi-dimensional empathy scal…

Psychological and weight-related characteristics of patients with anorexia nervosa-restricting type who later develop bulimia nervosa
BACKGROUND: Patients with anorexia nervosa-restricting type (AN-R) sometimes develop accompanying bulimic symptoms or the full syndrome of bulimia nervosa (BN). If clinicians could predict who might change into the bulimic sub-type or BN, preventative steps could be taken. Therefore, we investigated anthropometric and psychological factors possibly associated with such changes. METHOD: All participants were from a study by the Japanese Genetic Re…
Age and gender effect on alexithymia in large, Japanese community and clinical samples
BACKGROUND: The construct validity of alexithymia and its assessment using the 20-item Toronto Alexithymia Scale (TAS-20) in Japan is unknown. Low reliability has been found for the third factor of the TAS-20 in some cultures, and the factor structure for psychosomatic disorder patients has not been adequately investigated. Although alexithymia most likely has certain developmental aspects, this has infrequently been investigated. METHODS: The ne…
Development of the Overt-Covert Aggression Inventory
The expression of anger in Japanese people is different from that of other races. We developed a new brief inventory, the Overt-Covert Aggression Inventory, to assess aggressive behavior ofJapanese people by focusing on their uniqueness and examined its reliability and validity. This inventory, the Center for Epidemiological Studies Depression scale, the Japanese version of the Buss-Perry Aggression Questionnaire, and the Picture-Frustration Stud…
Pancreatic abnormalities in patients with eating disorders
In patients with eating disorders, we evaluated pancreatic abnormalities using serum elastase 1 measurement by RIA and the 50 g oral glucose tolerance test (50 g OGTT). Twenty-one patients had anorexia nervosa (AN) with bulimia and vomiting (AN-B group), 30 had AN without bulimia or vomiting (AN-R group), and 25 had bulimia with normal body weight (B group). The serum elastase 1 level was determined on admission and repeated after body weight gai…
