“…Outcome measures for mental health were obtained using two separate instruments: 1) the 12-item Short Form (SF-12) Health Survey, a validated measure of health status for homeless populations (Larson, 2002;Ware, Kosinski, & Keller, 1995); and 2) the Addiction Severity Index (ASI) (McGahan, Griffith, Parente, & McLellan, 1986;McLellan et al, 1992), a validated indicator for mental health, alcohol and drug problems that has been used in numerous studies (Burt, Aron, & Lee, 2001;Drake, McHugo, & Biesanz, 1995;Joyner, Wright, & Devine, 1996;Zanis, McLellan, Cnaan, & Randall, 1994). SF-12 physical component summary (PCS) and mental component summary (MCS) scores were calculated according to the publishers' specifications (Ware et al, 1995).…”

The purpose of this study was to estimate the prevalence of mental health problems among a representative sample of homeless women with and without dependent children and determine if the effects of risk factors for mental health are modified by the presence of dependent children. Homeless women (n=522) were recruited in 2004-2005 from shelters and meal programs in Toronto, Canada. Linear and logistic regression was performed to identify factors associated with mental health status. Poor mental health was associated with low perceived access to social support, physical/sexual assault in the past 12 months, presence of a chronic health condition, and presence of a drug use problem in the past month. Efforts to improve mental health in this population will need to address the associated problems of victimization, substance abuse, and lack of social supports.

“…24 We dichotomized problems as being present or absent with cut-off scores established for homeless populations. 13 These criteria included the classification of participants as having a mental health problem if their ASI mental health score was 0.25 or greater, an alcohol problem if their ASI alcohol score was 0.…”

Objectives. We examined the extent of unmet needs and barriers to accessing health care among homeless people within a universal health insurance system. Methods. We randomly selected a representative sample of 1169 homeless individuals at shelters and meal programs in Toronto, Ontario. We determined the prevalence of self-reported unmet needs for health care in the past 12 months and used regression analyses to identify factors associated with unmet needs. Results. Unmet health care needs were reported by 17% of participants. Compared with Toronto's general population, unmet needs were significantly more common among homeless individuals, particularly among homeless women with dependent children. Factors independently associated with a greater likelihood of unmet needs were younger age, having been a victim of physical assault in the past 12 months, and lower mental and physical health scores on the 12-Item Short Form Health Survey. Conclusions. Within a system of universal health insurance, homeless people still encounter barriers to obtaining health care. Strategies to reduce nonfinancial barriers faced by homeless women with children, younger adults, and recent victims of physical assault should be explored.

CMAJ ResearchBackground: We sought to determine the lifetime prevalence of traumatic brain injury and its association with current health conditions in a representative sample of homeless people in Toronto, Ontario. Methods:We surveyed 601 men and 303 women at homeless shelters and meal programs in 2004-2005 (response rate 76%). We defined traumatic brain injury as any self-reported head injury that left the person dazed, confused, disoriented or unconscious. Injuries resulting in unconsciousness lasting 30 minutes or longer were defined as moderate or severe. We assessed mental health, alcohol and drug problems in the past 30 days using the Addiction Severity Index. Physical and mental health status was assessed using the SF-12 health survey. We examined associations between traumatic brain injury and health conditions. Results:The lifetime prevalence among homeless participants was 53% for any traumatic brain injury and 12% for moderate or severe traumatic brain injury. For 70% of respondents, their first traumatic brain injury occurred before the onset of homelessness. After adjustment for demographic characteristics and lifetime duration of homelessness, a history of moderate or severe traumatic brain injury was associated with significantly increased likelihood of seizures (odds ratio [OR] 3.2, 95% confidence interval [CI] 1.8 to 5.6), mental health problems (OR 2.5, 95% CI 1.5 to 4.1), drug problems (OR 1.6, 95% CI 1.1 to 2.5), poorer physical health status (-8.3 points, 95% CI -11.1 to -5.5) and poorer mental health status (-6.0 points, 95% CI -8.3 to -3.7).Interpretation: Prior traumatic brain injury is very common among homeless people and is associated with poorer health.
