PURPOSE: to test of the reliability and validity of the Disabled's Motivation for Rehabilitation Scale. which was developed in 2002. METHOD: An experimental version of the scale was distributed to a sample of 441 disabled with ages above 18 and below 80 years. The subjects of the test-retest were 60 disabled. RESULTS: revealed a satisfactory level of test-retest and internal consistency. The overall fit of the factor model to the data was good. Correlation among the subscales revealed a simple pattern that, in general. provides support for the self- determination continuum and the construct validity. In testing concurrent, criterion-validity, there was a positive correlation between the motivation scores for rehabilitation and the Health-Related Hardiness scores and a negative correlation between the motivation scores for rehabilitation and the Learned Helplessness scores. CONCLUSION: The Disabled's Motivation for Rehabilitation Scale revealed a useful instrument with a high degree of reliability and validity. In this sense, this instrument can be effectively utilized in rehabilitative nursing for the disabled.

Although diabetes mellitus (DM) is treatable, it is still not curable. Its chronicity is associated with a high prevalence of psychiatric disorders, especially depression in type 2 DM and learned helplessness in type 1 DM. In turn, this depression and helplessness may affect a patient's adherence to medical appointments, compliance to treatment, and effective doctor-patient relationships, which are vital to promising outcomes. This study reviews the existing literature regarding the interactional relationships between depression, DM and the doctor/patient relationship, and also suggests certain aspects of the doctor/patient relationship which can contribute to more successful treatment outcomes.

Depression is one of the most common disease, but the pathophysiologic mechanism of depression remains elusive. To elucidate the cellular and molecular mechanisms of depression, animal models of depression have been developed, and these models were used successfully to predict the clinical efficacy of new antidepressant drugs. However, it is not likely that current animal models imitate all aspects of depression and are reliable, because we can not evaluate emotional state of rodents verbally and rodents have very different behavioral responses compared with ours. Despite these difficulties, understanding the benefits and limitations of animal models is very important for an advance in basic and clinical research of depression. The first part of the review evaluates animal models of depression in relation with stress that may contribute, in part, to development of depression: chronic mild stress, chronic unpredictable stress, maternal separation. The second part describes the most widely used animal models to screen for potential antidepressant: learned helplessness model and forced swimming test.

The purpose of this study was to identify the degree of learned helplessness and self-care agency in dialysis patients and the relationship between learned helplessness and self-care agency. The subjects were 168 dialysis patients who were undergoing hemodialysis and peritoneal dialysis from 1 university hospital, 1 hospital, 1 hemodialysis center in Seoul, 1 hospital in Incheon, Korea. The data were collected with two interview questionnaires which were Learned Helplessness Scale (LHS) and Self-as-Carer Inventory (SCI). The collected data were analyzed by descriptive statistics and t-test, One-way ANOVA and Pearson Correlation with SPSSWIN program. Results were obtained as follows : 1) The mean scores of learned helplessness were 45.93(range 20-80). The mean learned helplessness scores of peritoneal dialysis patient and hemodialysis (HD) patient were not different significantly. However by the aging process, the mean scores of learned helplessness has a tendency to get higher and who had a job were likely to low score of learned helplessness. 2) The mean scores of self-care agency were 142.48 (range 33-198). The mean self-care agency scores of peritoneal dialysis (PD) patient much higher than the score of it with hemodialysis. The score of self-care agency were significantly different between peritoneal dialysis patient and hemodialysis patient. The patients who have job were likely to be higher score of self-care agency than other groups. 3) There was significant relationship between the score of learned helplessness and self-care agency. In conclusion, there was an inverse relationship between learned helplessness and self-care agency in dialysis patients. Considering this, the high level of learned helplessness of dialysis patients should be intervened by nurse with a well developed edicational program or cognitive behavioral therapy.

BACKGROUND/AIMS: Although studies using conventional animal models have shown that specific stressors cause irritable bowel syndrome (IBS), it is unclear whether depression itself causes IBS. Our aim was to establish a rat model to determine if depression itself promotes the onset of IBS and to elucidate the role of gut microbiota in brain-gut axis pathogenesis during coincident depression and IBS. METHODS: Rat models of depression were induced using our shuttle box method of learned helplessness. Visceral hypersensitivity was evaluated by colorectal distension (CRD) to diagnose IBS. Gut microbiota compositions were analyzed using high-throughput sequencing. In the subanalysis of rats without depression-like symptoms, rats with posttraumatic stress disorder (PTSD) were also examined. RESULTS: The threshold value of CRD in depressed rats was significantly lower than that in control rats. Microbial community analysis of cecal microbiota showed that the relative abundance of Clostridiales incertae sedis, the most prevalent microbe, was significantly lower in depressed rats than in control rats. The distribution pattern of the microbiota clearly differed between depressed rats and control rats. Neither visceral hypersensitivity nor the composition of gut microbiota was altered in rats with PTSD-like phenotypes. CONCLUSIONS: Our rat model of depression is useful for clarifying the effect of depression on IBS and suggests that depression itself, rather than specific stressors, promotes the onset of IBS. Further, we provided evidence that various psychiatric diseases, viz., depression and PTSD, are associated with unique gut microbiota profiles, which could differentially affect the onset and progression of coincident IBS.

To investigate the behavioral and biomolecular similarity between neuralgia and depression, a trigeminal neuralgia (TN) mouse model was established by constriction of the infraorbital nerve (CION) to mimic clinical trigeminal neuropathic pain. A mouse learned helplessness (LH) model was developed to investigate inescapable foot-shock-induced psychiatric disorders like depression in humans. Mass spectrometry was used to assess changes in the biomolecules and signaling pathways in the hippocampus from TN or LH mice. TN mice developed not only significant mechanical allodynia but also depressive-like behaviors (mainly behavioral despair) at 2 weeks after CION, similar to LH mice. MS analysis demonstrated common and distinctive protein changes in the hippocampus between groups. Many protein function families (such as cell-to-cell signaling and interaction, and cell assembly and organization,) and signaling pathways (e.g., the Huntington's disease pathway) were involved in chronic neuralgia and depression. Together, these results demonstrated that the LH and TN models both develop depressive-like behaviors, and revealed the involvement of many psychiatric disorder-related biomolecules/pathways in the pathogenesis of TN and LH.
