Research has investigated testosterone and its role in biological and psychological functioning. Testosterone levels decrease as men age, and aging has been associated with declines in muscle mass and strength. Decreased functional mobility can impact quality of life. Aging has also been associated with increased vulnerability to depressive symptomatology. The purpose of this study was to investigate interrelationships among testosterone, physical functioning, quality of life, and depression in the Vietnam Era Twin Study of Aging (VETSA). The mean age of the 1,237 men in VETSA was 55.4 (+2.5). Testosterone data collection began in the third year of VETSA, yielding an available sample of 778. It was hypothesized that there would be significant associations between testosterone and physical functioning, depression, and quality of life as well as between physical functioning and depression and quality of life. Contrary to expectations, when mixed models for linear regression were used, testosterone was shown to be related only to physical functioning. As predicted, however, physical functioning was significantly related to depression and quality of life. Cholesky decompositions were conducted to address the hypothesis that there were shared genetic determinants of each phenotype. Best fitting bivariate models included additive genetic and unique environmental but not common environmental influences. Significant genetic correlations were found between physical functioning and depression, and physical functioning and the mental health component score of the Short Form Health Survey (SF-36). Contrary to expectations, while testosterone and physical functioning were significantly correlated with each other phenotypically, there was no genetic correlation between the two. Trivariate models revealed genetic influences specific to depression as well as genetic influences shared with quality of life and depression. Finally, path analysis demonstrated that testosterone had a direct impact on physical functioning. Physical functioning, but not testosterone, directly impacted depression and quality of life. As there was no genetic correlation between testosterone and physical functioning, but there was a phenotypic correlation, it may be that other factors, such as cortisol, influenced the association. In sum, in this sample, physical functioning seemed to be more important than testosterone to both depressive symptomatology and quality of life.

Demographics indicate that the United States and many other industrialized nations are currently experiencing what is called the ¡°graying¡± of the workforce (Hayslip & Panek, 1993). Today the majority of the workers in many companies are in the age groups of 40-44 and 45-49 years. However, by the year 2010, the largest proportion of workers will probably be in the age groups of 55-59 and 60-64 years (Ilmarinen, 1995). Thus, a growing concern of employers in the near future will be the assignment of older workers to specific job tasks and responsibilities (Williams & Crumpton, 1996) as well as other issues pertinent to the employment of older workers. As workers age they typically experience physiological and psychological changes which must be estimated to minimize the mismatch between their capabilities and job demands as well as to prevent work related injuries such as over exertion injuries. Early identification of declines in work ability and implementation of ergonomic interventions are key to sustaining older and more experienced workers in the workplace (Williams et al., 1996). If preventive measures are not taken, older employees are likely to experience a decline in work capacities (Ilmarinen, 1994). Therefore, reliable and valid measures of one¡¯s ability to perform physical work activities are essential for preventing work-related injuries. Hence, the focus of this research project is to develop a diagnostic tool that can be used by employers to estimate their workers¡¯ ability to perform daily work activities. Specifically, the Williams Work Estimator (W2E) is designed to provide information concerning workers¡¯ ability to perform physical work activities such as lifting, lowering, pushing, pulling, etc. A field research study involving 32 employees at a beer distribution warehousing facility was conducted to evaluate the following attributes of the W2E: (a) test-retest reliability, (b) concurrent criterion validity, and (c) predictive validity. Test-retest reliability of the W2E was assessed using Pearson correlation coefficients. The overall correlation coefficients obtained on both the task evaluation (.64) and the self-evaluation (.58) were near minimal acceptable levels (.60 or greater) for each job task evaluated. In addition, the W2E ranged from 50 to 100% accurate when identifying persons who had experienced a work-related injury within the past year. Findings of this research study suggest the W2E represents a promising new tool for assessing work capability and deserves further study to improve reliability and validity.

This study investigated the mental and physical health of early adolescents (n = 339) using a dual-factor model of mental health. When employing a dual-factor model, mental well-being is not simply assumed from the absence of negative indicators of mental health (psychopathology). Rather, assessments of positive indicators of mental health (subjective well-being) are used to determine one's level of mental wellness. The current study tested the existence of a dual-factor model of mental health by examining the separability of participants' reports of subjective well-being and psychopathology. Specifically, the researcher hypothesized that the assessment of both of these constructs would result in multiple mental health classifications, beyond that of the continuum found with only the assessment of psychopathology (i.e., low to high psychopathology). Findings from this study support the classifications of four mental health groups using measures of subjective well-being and psychopathology. In addition, significant differences in physical health outcomes were found among participants in the different mental health groups. These findings support the existence of a dual-factor model of mental health, and suggest the need for assessment of both negative and positive indicators of functioning in order to accurately estimate adolescents' physical health.

No / The objective of this article was to evaluate the effectiveness of pharmacist-led medication review in chronic pain management. Six electronic databases (Medline, Embase, PsycInfo, CINHAL, CENTRAL, International Pharmaceutical Abstracts) reference lists of retrieved articles and relevant websites were searched for randomized controlled trials published in the English language involving adults with chronic pain. Studies were included if one of the intervention arms had received pharmacist-led medication review independently or as part of a multidisciplinary intervention. Risk of bias was assessed for all the included studies. The search strategy yielded 583 unique articles including 5 randomized controlled trials. Compared with control, meta-analysis showed that participants in the intervention group had: a 0.8-point reduction in pain intensity on a 0 to 10 numerical rating scale at 3 months [95% confidence interval (CI), -1.28 to -0.36] and a 0.7-point reduction (95% CI, -1.19 to -0.20) at 6 months; a 4.84 point (95% CI, -7.38 to -2.29) and -3.82 point (95% CI, -6.49 to -1.14) improvement in physical functioning on a 0- to 68-point function subscale of Western Ontario and McMaster Universities Osteoarthritis Index at 3 and 6 months, respectively; and a significant improvement in patient satisfaction equivalent to a "small to moderate effect." Pharmacist-led medication review reduces pain intensity and improves physical functioning and patient satisfaction. However, the clinical significance of these findings remain uncertain due to small effect size and nature of reported data within clinical trials that limits recommendation of wider clinical role of pharmacist in chronic pain management.

Two instruments were developed and administered to fifteen female and three male rheumatoid arthritics (mean age 44) previously hospitalized for allergy treatment by ecological methods. The Physical Functioning Ability Scale assessed functional capacity according to common daily activities, and the Rehabilitation Questionnaire surveyed adjustment problems subjects encountered after hospital discharge. ANOVA was performed on the functionality scale comparing dimensions of dependence, pain, and difficulty with categorical activities of mobility, work, and personal care, Significant F values (p(.05) were obtained for interaction and dimensions, but not for categories. Functional independence from human/mechanical assistance was particularly noted. Recommendation for future research concerns replicating this study using a control group of rheumatoid arthritics treated by traditional medical approaches.

Doctor of philosophy (PhD) / Abstract As one of the most culturally diverse countries in the world, Australia has a high proportion of minority communities. However, its ageing population, particularly within these ethnic minorities, faces a range of barriers or difficulties in gaining access to and using health and aged care services. This study aims to identify the acculturation factors that affect the health status of Iranian-born elderly immigrants to Australia and their utilisation of health and community aged care services. The results of this study will be of value to Iranian elders, their families, and Australian aged health care service providers. The findings could also contribute towards enriched multicultural policy and improved social fairness, access to services, and equity for the aged from different ethnic backgrounds. 302 Iranian migrants aged 65 years who had lived in the Sydney Metropolitan area for at least six months were surveyed via a written questionnaire, face-to-face interviews, and telephone interviews. The results were analysed using SPSS and then compared to the findings from a 1999 survey of NSW elderly. The results indicate that Iranian migrants suffer higher levels of psychological distress and are more limited in their physical functioning than the general population of older Australians. They are in greater need of assistance with activities of daily living, have a lower sense of wellbeing, and are far less likely to utilise aged care services. Iranian migrant who do not speak English at home experience these disadvantages to an even greater extent English language proficiency was the only acculturation factor found to affect whether Iranian elderly utilised health and community aged care services, while ability to engage in activities of daily living (ADL) was the only health variable associated with their utilisation of community supportive aged care services. This variable did not predict the use of community aged care services in the broader sample of NSW respondents. Since limited proficiency in English placed elderly Iranian migrants at greater health risk and impeded their access to necessary assistance, the findings suggest that they would clearly benefit from English classes and from access to health and community care services and information regarding these services in the Farsi language.
