This investigation examined cognitive impairment as a predictor of the volume of community services used by older adults. Predictors of service volume were selected according to the modified Andersen framework and tested with 97 health care and 246 social service clients of a large multiservice agency. Results for health care clients showed that the effects of four predictors differ depending on clients' level of cognitive impairment; living arrangement, presence of secondary caregivers, client depression and task burden of the primary caregiver. No differences in predictor of social service use were observed for cognitively impaired and lucid clients.

The utility of Andersen's (1993, 1994) model of psychologic morbidity following cancer treatment for predicting PTSD symptoms in breast cancer survivors (N = 82) was examined. PTSD symptoms, physical comorbidity, social support, depression history, and pre-cancer traumatic stressors were assessed in a structured telephone interview. Multiple regression analysis indicated that Andersen model variables (physical comorbidity, education, disease stage, cancer treatment, depression history, social support) accounted for 39% of variance in PTSD symptom reports (p < .001). Addition to the model of time since treatment completion, pre-cancer traumatic stressors, age at diagnosis, and tamoxifen usage accounted for an additional 16% of variance (p < .001). Higher levels of PTSD symptoms were associated with less social support, greater pre-cancer trauma history, less time since treatment completion, and more advanced disease.

Two studies examined depressed and nondepressed perceivers' characterizations and thoughtful inferences about the behaviors of another person. In Study 1, depressed and nondepressed participants under a cognitive load or no load were asked to make either dispositional (ability) or situational (task ease) inferences about a target's videotaped performance. When cognitive resources were limited, depressed compared with nondepressed individuals made more pessimistic characterizations. No depression-related differences were found when sufficient cognitive resources were available for inferential correction. Study 2 provided evidence that the depressed-nondepressed differences in characterizations could be accounted for by schema-based future-event expectancies (S. M. Andersen, L. A. Spielman, & J. A. Bargh, 1992). Results are examined in light of previous failures to find consistent differences as a function of level of depression in inferences about others.

The objective of this paper is to identify predictors of health care utilization in the chronically ill. This paper reviews 53 studies on hospitalizations and physician visits, published between 1966 and 1997 and identified by MEDLINE and ClinPSYCH databases. Studies with both univariate and multivariate analyses were included. On the basis of the Andersen-Newman model of health care utilization, the effects of predisposing, enabling and need variables are examined. Most studies reviewed indicate that predisposing factors such as age, sex, and marital status are not predictors of hospital utilization in the chronically ill. The enabling factors income, insurance and social support have not been shown to affect health care utilization, but characteristics of the hospitals could have an effect. Need factors such as disease severity, symptom severity and complications adversely affected health care utilization in the chronically ill, while disease duration and comorbidity do not have such an effect. Quality of life and perceived health might affect hospital utilization and physician use. Finally, depression and psychological distress proved to be among the strongest predictors of hospitalizations and physician visits. In conclusion, both disease severity and psychological well-being are most important in health care utilization. Intervention programs to support depressed or psychologically distressed patients should be considered. These could both help the patient and reduce health care utilization costs.

Depression is the most common psychiatric disturbance in Parkinson's disease. We conducted a Cochrane systematic review to assess the efficacy and safety of antidepressant therapies in idiopathic Parkinson's disease. Relevant trials were identified from electronic databases, reference lists and queries to antidepressant manufacturers. Three randomised controlled trials examined oral antidepressants in 106 patients with Parkinson's disease. No eligible trials of electroconvulsive or behavioural therapy were found. In the first arm of the crossover trial by Andersen et al. (n=22), nortriptyline treated patients showed a larger improvement than placebo in a unique depression rating scale after 16 weeks although significance levels were not provided. A parallel group trial by Wermuth et al. (n=37) did not show any significant difference between citalopram and placebo in Hamilton score after 52 weeks. Rabey et al. (n=47) performed an open-label trial comparing fluvoxamine with amitriptyline. Similar numbers in each group had a 50% reduction in Hamilton score after 16 months. Major side effects including visual hallucinations and confusion were reported with fluvoxamine and amitriptyline. Insufficient data on the effectiveness and safety of antidepressant therapies in Parkinson's disease are available on which to make recommendations for their use. Large scale randomised controlled trials are urgently required.

The Future Events Scale (FES; S. M. Andersen, 1990) is an expectancy-based measure of optimism and pessimism, grounded in cognitive theories of depression, with implications for clinical practice. Although ample research has documented the utility of the FES in predicting important cognitive and behavioral outcomes, psychometric data on the scale are lacking. The current article presents multisample analyses to show that the FES has clear factor structure, good reliability, and a theoretically meaningful nomological network. The FES is shown to be distinct from the best known measure of optimism and pessimism, the Life Orientation Test (M. F. Scheier & C. S. Carver, 1985). Applications are discussed.

A previous study on spray-drying demonstrated that it could promote the solubility of poorly water-soluble drugs using water-soluble polymers. Here, the preparation of composite particles of salbutamol sulfate (Sb) with water-insoluble polymers, such as Eudragit RS (RS) or Eudragit RL (RL) as a carrier, was examined. Despite the water insolubility of both polymers, the permeability of water was low in the former but high in the latter. We attempted to prepare controlled release composite particles by exploiting the characteristics of these carriers. The composite particles of the three components (Sb, RS, and RL) were prepared using a 4-fluid nozzle spray-dryer, and their physico-chemical and dissolution properties were compared with physical mixtures. Examination of particle morphology by scanning electron microscopy (SEM) revealed that the particles from the spray-drying process had atomized to several microns and were spherical. Analysis by X-ray diffraction and differential scanning calorimetry revealed that diffraction peaks and heat of fusion of Sb in the spray-dried samples decreased, indicating that the drug was amorphous and formed a solid dispersion. FT-IR analysis suggested that the amino group of Sb and a carbonyl group of the polymers formed a hydrogen bond. A dissolution test of Sb-RS-RL particles prepared using the 4-fluid nozzle spray-drying method showed that release rates were depressed significantly compared to the physical mixture at pH 1.2 and 6.8, and the depression was greater when RS was used instead of RL, presumably because of the permeability difference. The compression of these particles into tablets revealed that desirable controlled released dosage forms could be prepared. In addition, Sb was used to simulate an anti-asthmatic drug. For this an Andersen cascade impactor for dry powder inhalers was used to investigate delivery to the lungs.

The present study examined the attitudes toward mental health services held by younger (aged 20-45, n = 209) and older (aged 60 and older, n = 462) groups of Korean Americans. Following Andersen's (1968; A behavioral model of families' use of health service, Center for Health Administration Studies) behavioral health model, predisposing (age, gender, marital status and education), need (anxiety and depressive symptoms) and enabling (acculturation, health insurance coverage and personal experience and beliefs) variables were considered. In the mean-level assessment, younger and older adults were found to hold a similar level of positive attitudes toward mental health services. In the multivariate analysis, culture-influenced beliefs were shown to have a substantial contribution to the model of attitudes toward mental health services in both age groups. The belief that depression is a medical condition was found to be a common predictor of positive attitudes across the groups. In the older adult sample, more negative attitudes were observed among those who believed that depression is a sign of personal weakness and that having a mentally ill family member brings shame to the whole family. Our findings show that older adults are not only more subject to cultural misconceptions and stigma related to mental disorders, but also their attitudes toward service use are negatively influenced by the cultural stigma. The findings provide important implications for interventions targeted to improve access to mental health care among minority populations. Based on the similarities and differences found between young and old, both general and age-specific strategies need to be developed in order to increase effectiveness of these programs.

Executive functions and social cognition develop through childhood into adolescence and early adulthood and are important for adaptive goal-oriented behavior (Apperly, Samson, & Humphreys, 2009; Blakemore & Choudhury, 2006). These functions are attributed to frontal networks known to undergo protracted maturation into early adulthood (Barker, Andrade, Morton, Romanowski, & Bowles, 2010; Lebel, Walker, Leemans, Phillips, & Beaulieu, 2008), although social cognition functions are also associated with widely distributed networks. Previously, nonlinear development has been reported around puberty on an emotion match-to-sample task (McGivern, Andersen, Byrd, Mutter, & Reilly, 2002) and for IQ in midadolescence (Ramsden et al., 2011). However, there are currently little data on the typical development of social and executive functions in late adolescence and early adulthood. In a cross-sectional design, 98 participants completed tests of social cognition and executive function, Wechsler Abbreviated Scale of Intelligence (Wechsler, 1999), Positive and Negative Affect Schedule (Watson, Clark, & Tellegen, 1988), Hospital Anxiety and Depression Scale (Zigmond & Snaith, 1983), and measures of pubertal development and demographics at ages 17, 18, and 19. Nonlinear age differences for letter fluency and concept formation executive functions were found, with a trough in functional ability in 18-year-olds compared with other groups. There were no age group differences on social cognition measures. Gender accounted for differences on 1 scale of concept formation, 1 dynamic social interaction scale, and 2 empathy scales. The clinical, developmental, and educational implications of these findings are discussed.

This study adapted Andersen's Health Belief Model to examine the predictors of mental health services utilization among Korean American (KA) immigrants. A cross-sectional survey was used to gather data on 363 KA immigrants 18 years and older residing in New York City. Predisposing factors included gender, age, marital status, education, length of stay in the US, and religion; the need factor was depression; and enabling factors included health insurance, English proficiency, income, and perceived need for help. Approximately 8.5 % of participants reported having utilized mental health services, while 23 % reported having depressive symptoms. Shorter duration of residence in the US, lower income, and the presence of perceived need for help were significantly related to use of mental health services. The perceived need for help mediated the relationship between depression and mental health service utilization. Failure to perceive the need for psychological help continues to be a major reason that KA immigrants do not use mental health services.
