Aim Many studies have reported that the prevalence of mental illness and cognitive disability is higher among homeless individuals compared to the general population, and the rates of mental illness among the homeless population have recently increased. This study: (i) compares causes of homelessness or barriers to escaping homelessness for people with/without mental illness/cognitive disability; (ii) reveals problems with the Japanese homeless policy; and (iii) proposes an effective and necessary support system. Methods The participants were 114 homeless individuals. A psychiatric diagnostic interview and the Wechsler Adult Intelligence Scale, version III were used to measure participants' mental health and cognitive abilities. A questionnaire was administered comprising 17 items related to the causes of their homelessness and barriers to escaping from it. Participants were divided into four groups - with/without mental illness or cognitive disability - and Fisher's exact test was used to compare the questionnaire results. Results Individuals with cognitive disabilities considered bad relationships with their family members to be the cause of their homelessness. Conversely, normal individuals considered their homelessness to be the result of debt more so than did individuals with mental problems. Individuals with mental illness had more difficulties escaping homelessness than did either normal individuals or individuals with cognitive disability. This tendency was observed most strongly among individuals with both mental illness and cognitive disability. Conclusion Most homeless individuals considered economic problems to be the cause of their homelessness; however, difficulties with human relationships were also important factors and were more difficult for participants to acknowledge. Furthermore, these difficulties were exacerbated among those individuals with mental problems. [ABSTRACT FROM AUTHOR]

Aim While it has been reported that the prevalence of mental illness is higher in homeless people than in the national population, few studies have investigated the prevalence of intellectual and developmental disability among the homeless. In this study, we conducted a survey to comprehensively assess these mental problems among homeless people in Nagoya, Japan. Methods The subjects were 18 homeless men. Mental illness was diagnosed with semi-structured interviews conducted by psychiatrists. We used the Wechsler Adult Intelligence Scale III to diagnose intellectual disability. Discrepancies between Wechsler Adult Intelligence Scale III subtest scores were used as criteria for developmental disability. Results Eleven of the 18 participants were diagnosed with mental illness: six with mood disorder, two with psychotic disorder, and six with alcohol problems. The mean IQ of all subjects was 83.4 ± 27.4. The 95% confidence interval ( CI) was 96.2-69.1. Seven participants were found to have intellectual disability. Three men showed discrepancies of more than 10 between subtest scores, and all of them were diagnosed with a mental illness. We divided the participants into four groups: those with mental illness only; those with intellectual disability only; those with both problems; and those without diagnosis. The men with intellectual disability only were significantly younger and had been homeless since a younger age than the other groups. Participants diagnosed with a mental illness had been homeless for longer than those without mental health problems. Conclusion Although the sample size was limited, this study revealed the high prevalence of mental illness and intellectual disability, 61% (95% CI, 35-83%) and 39% (95%CI, 17-64%), respectively, in homeless people in Nagoya, Japan.

Aims: The relationship between suicide and disaster is an important problem but it's not clear. We conducted this study to determine whether a natural disaster affects suicide rates. Methods: We collected data on suicides during the 84 months before and the 60 months after the earthquake and compared the suicide rate in Kobe to that in Japan as a whole. We also examined what groups were significantly affected. Results: Compared with Japan as a whole, the suicide rates in Kobe significantly decreased in the 2 years after the earthquake. Conclusions: An influence on suicide rate after the disaster clearly appeared in middle-aged men. [ABSTRACT FROM AUTHOR]
