BACKGROUND Psychological distress is frequently observed, however, it is underestimated in cancer patients. The aim of this study is to develop a simple battery for screening for psychological distress, adjustment disorder and major depressive disorder in Japanese cancer patients. METHODS One hundred and twenty-eight cancer patients were interviewed by(More)
BACKGROUND Few studies have investigated the predictive value of central serotonin transporter (SERT) availability for treatment response to serotonin reuptake inhibitors (SSRIs). This study used brain imaging to examine the relationship between pretreatment brain SERT availability and transporter occupancy by SSRIs with treatment response in two(More)
Few studies have demonstrated in vivo alterations of human serotonin and dopamine transporters (SERTS and DATS) during antidepressant treatment. The current study measured these transporter availabilities with [(123)I]beta-CIT single photon emission computed tomography (SPECT) during administration of selective serotonin reuptake inhibitors (SSRIs) or a(More)
BACKGROUND To the authors' knowledge, there had been no evidence for the efficacy of psychosocial intervention among Japanese cancer patients. The objective of this study was to determine the effect of a psychosocial group intervention in reducing psychologic distress and enhancing coping in this population in a randomized controlled trial. METHODS The(More)
We herein describe the development and validation of the Cancer Fatigue Scale (CFS) for assessment of fatigue in cancer patients. We designed this scale specifically to reflect the nature of fatigue experienced by cancer patients, by using factor analysis; the CFS is a 15-item scale composed of 3 subscales (physical, affective, and cognitive subscales).(More)
 Fatigue is one of the most frequent symptoms in cancer patients. However, the precise causes of this fatigue are still unknown, and this situation makes it difficult to combat the problem. The present study was conducted to investigate factors correlated with fatigue in disease-free breast cancer patients. A group of 134 randomly selected ambulatory breast(More)
The monoamine theory has implicated abnormalities in serotonin and norepinephrine in the pathophysiology of major depression and bipolar illness and contributed greatly to our understanding of mood disorders and their treatment. Nevertheless, some limitations of this model still exist that require researchers and clinicians to seek further explanation and(More)
BACKGROUND Major depression is more prevalent in women than men. The present study evaluated if previous findings that demonstrated decreased 5-hydroxytryptamine (5-HT) transporter availability in depressed patients would be confirmed in a larger sample and also evaluated sex differences. METHODS Depressed (n = 32) and healthy subjects (n = 32), including(More)
This paper describes a study of the psychometric properties of the Japanese version of the mental adjustment to cancer (MAC) scale developed in England. The scale was completed by 455 Japanese cancer patients. The internal consistency was similar to that of the original version (Cronbach's alpha coefficients for the subscales ranged from 0.60 to 0.78) and(More)
High levels of psychological distress, especially depressed mood, has been discussed in relation to head and neck cancer. Patients with head and neck cancer face functional impairment and disfigurement caused by cancer and/or its treatment. Psychosocial factors that predict depressed mood in this population have not been well elucidated. The aim of this(More)
