Comparing the housing trajectories of different classes within a diverse homeless population.

The paper presents findings from a longitudinal study identifying different classes of homeless individuals in a mid-size Canadian city based on health-related characteristics and comparing the housing trajectories of these classes 2 years later. Using data collected through in-person interviews with a sample of 329 single persons who have experienced homelessness, the paper presents results of a latent class analysis. Results found four distinct latent classes characterized by different levels of severity of health problems--i.e., a class of individuals who are "Higher Functioning" (28.7%), a second class with "Substance Abuse Problems" (27.1%), a third class with "Mental Health Substance Abuse Problems" (22.6%), and a fourth class with "Complex Physical and Mental Health Problems" (21.6%) that included having diminished physical functioning, multiple chronic physical health conditions, mental health difficulties, and in some cases substance abuse problems. Follow-up interviews with 197 of these individuals (59.9%) 2 years later showed the class of individuals with substance abuse problems experiencing the greatest difficulty in exiting homelessness and achieving housing stability. Implications of these findings for social policy development and program planning are discussed.

Factorial structure and psychometric properties of the reminiscence functions scale.

OBJECTIVES: This study reports on the psychometric properties and the factorial structure of the Reminiscence Functions Scale (RFS), a 43-item self-report instrument used to assess the frequencies of reminiscence for distinct functions. METHOD: The factorial validity (exploratory factor analysis, n = 453; confirmatory factor analysis, n = 456), the invariance of factorial structure across gender (males = 228; females = 240), and psychometric properties were examined. RESULTS: They support an eight-factor structure similar to the original one, yet question the value of a few of the items. Cronbach's alphas for the various subscales ranged from 0.76 to 0.87. Test-retest reliability ranged from r = 0.48-0.63. CONCLUSION: The RFS is confirmed as a psychometrically sound instrument for use in research on the functions of reminiscence with samples of older adults.

Exploratory factor analysis of neuropsychological tests and their relationship to the Brown-Peterson task.

The interference condition of the Brown-Peterson task and the auditory consonant trigrams test was designed to evaluate working memory in that it required a division of attentional processes to complete two cognitive tasks. However, the specific cognitive functions contributing to the performance of this interference task have yet to be determined. The objective of this study was to determine what other tasks are comparable to the Brown-Peterson task and conduct an exploratory factor analysis that included the measures from the Brown-Peterson task and other neuropsychological measures. A neuropsychological battery was administered to younger participants (n=107, mean age=20.83) and older participants (n=93, mean age=70.14). Factor analysis yielded a two-factor solution. Performance after the intervening serial subtraction task loaded on an auditory/visual working memory and complex attention factor and had common loadings with working memory subtests of the WAIS-III and the spatial span subtest of the WMS-III. Results suggest that the performance after the intervening serial subtraction task evaluates dual information processing, complex attention, and working memory.
