Validation of the Japanese version of the 8-item Chronic Pain Acceptance Questionnaire (CPAQ-8).

This study aimed to examine the reliability and validity of the Japanese version of the Chronic Pain Acceptance Questionnaire (CPAQ-8J). A total of 108 outpatients with chronic pain completed the CPAQ-8 questionnaire, along with the Acceptance and Action Questionnaire-II, Hospital Anxiety and Depression Scale, Pain Disability Assessment Scale, Numerical Rating Scale, and EuroQol 5 dimensions 5-level. Confirmatory factor analyses examined the factor structure.

Pilot study of a basic individualized cognitive behavioral therapy program for chronic pain in Japan.

Background: Chronic pain is a major health problem, and cognitive behavioral therapy (CBT) is its recommended treatment; however, efforts to develop CBT programs for chronic pain and assess their feasibility are remarkably delayed in Asia. Therefore, we conducted this pilot study to develop a basic individualized CBT for chronic pain (CBT-CP) and assessed its feasibility for use in Japan.

Methods: Our study was an open-labeled before-after trial without a control group conducted cooperatively in five Japanese tertiary care hospitals.

Visual Perception of Moisture Is a Pathogen Detection Mechanism of the Behavioral Immune System.

The behavioral immune system (BIS) includes perceptual mechanisms for detecting cues of contamination. Former studies have indicated that moisture has a disgusting property. Therefore, moisture could be a target for detecting contamination cues by the BIS.

Intraday Activity Levels May Better Reflect the Differences Between Major Depressive Disorder and Bipolar Disorder Than Average Daily Activity Levels.

It is important to establish an objective index to differentiate mood disorders (i.e., bipolar disorder; BD and major depressive disorder; MDD).

Factor Structure, Reliability, and Validity of the Japanese Version of the Disgust Propensity and Sensitivity Scale-Revised.

The Disgust Propensity and Sensitivity Scale-Revised is one of the most widely used measures of individual differences for the emotion of disgust. It consists of 2 subscales: disgust propensity and disgust sensitivity. This study examined the factor structure, reliability, and validity of the Japanese version of the revised Disgust Propensity and Sensitivity Scale.

Psychological Basis of the Relationship Between the Rorschach Texture Response and Adult Attachment: The Mediational Role of the Accessibility of Tactile Knowledge.

This study clarifies the psychological basis for the linkage between adult attachment and the texture response on the Rorschach by examining the mediational role of the accessibility of tactile knowledge. Japanese undergraduate students (n = 35) completed the Rorschach Inkblot Method, the Experiences in Close Relationship Scale for General Objects (Nakao & Kato, 2004) and a lexical decision task designed to measure the accessibility of tactile knowledge. A mediation analysis revealed that the accessibility of tactile knowledge partially mediates the association between attachment anxiety and the texture response.

Telephone cognitive-behavioral therapy for subthreshold depression and presenteeism in workplace: a randomized controlled trial.

Background: Subthreshold depression is highly prevalent in the general population and causes great loss to society especially in the form of reduced productivity while at work (presenteeism). We developed a highly-structured manualized eight-session cognitive-behavioral program with a focus on subthreshold depression in the workplace and to be administered via telephone by trained psychotherapists (tCBT).

Methods: We conducted a parallel-group, non-blinded randomized controlled trial of tCBT in addition to the pre-existing Employee Assistance Program (EAP) versus EAP alone among workers with subthreshold depression at a large manufacturing company in Japan.

Spindle epithelial tumor with thymus-like differentiation (SETTLE) of the thyroid.

Background: Tumors of the so-called intrathyroidal epithelial thymoma type are a rare group of thyroid neoplasm tumors. Of this type of tumor, spindle epithelial tumor with thymus like differentiation (SETTLE) has been reported only 17 times in English literature.

Methods: An 18-year-old woman was initially seen with a 6-cm left thyroid mass that was resected with a left thyroidectomy.
