Selected AbstractsThe influence of television on willingness to seek therapyJOURNAL OF CLINICAL PSYCHOLOGY, Issue 3 2008David L. Vogel Abstract Television portrayals of psychologists may be contributing to an unfavorable perception of mental health services. The present study (N=369) used structural equation modeling to examine the relationship between exposure to television programs, perceptions of therapy (i.e., perceived stigma, anticipated risks and benefits, and attitudes towards therapy), and intentions to seek therapy. The results demonstrated that (a) the relationship between television exposure and attitudes was fully mediated by stigma and anticipated benefits, and (b) the relationship between television exposure and intentions to seek therapy was fully mediated by attitudes, stigma, and anticipated benefits. Furthermore, 54% of the variance in attitudes and 47% of the variance in intentions was accounted for by the variables in the model. © 2008 Wiley Periodicals, Inc. J Clin Psychol. 64: 1,20, 2008. [source] Social support, psychiatric symptoms, and housing: A causal analysisJOURNAL OF COMMUNITY PSYCHOLOGY, Issue 3 2002Robert J. Calsyn This study used structural equation modeling to examine the causal relationship between social support and each of three outcome variables: depression, psychotic symptoms, and stable housing. Two measures of social support were included in the models: natural support (family and friends) and professional support. Nearly 4,000 individuals from 18 cities in the United States provided data for this study. All participants were homeless at baseline and suffered from severe mental illness. Data were collected at baseline, 3 months, and 1 year. A reciprocal effects model best explained the causal relationship between social support and psychiatric symptoms. The social causation model best explained the relationship between social support and stable housing, such that increases in social support led to increases in stable housing. © 2002 Wiley Periodicals, Inc. [source] Longitudinal Studies of Anger and Attention Span: Context and Informant EffectsJOURNAL OF PERSONALITY, Issue 2 2010Jungmeen Kim ABSTRACT This study examined stabilities of informant and context (home vs. classroom) latent factors regarding anger and attention. Participants included children from the National Institute of Child Health and Development Study of Early Child Care and Youth Development who were measured at 54 months, first grade, and third grade. Latent factors of anger and attention span were structured using different indicators based on mothers', fathers', caregivers', teachers', and observers' reports. We used structural equation modeling to examine the autoregressive effects within a context (stability), the concurrent associations between home and classroom contexts, and informant effects. The results indicated that for both anger and attention (1) there were significant informant effects that influenced stability in a context, (2) there was higher stability in home context than nonhome context, and (3) stability within a context increased over time. The findings suggested that anger was more prone to context effects and informant effects than attention. [source] The Impact of HIV on Oral Health and Subsequent Use of Dental ServicesJOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 2 2003Aram Dobalian PhD Abstract Objective: This study examined differences in health and access to dental services among a nationally representative sample of patients with HIV using Andersen's Behavioral Model of Health Services Use. Methods: This investigation is a longitudinal study that used structural equation modeling to analyze data from the HIV Cost and Services Utilization Study, a probability sample of 2,864 adults under treatment for HIV infection. Key predisposing variables included sex, drug use, race/ethnicity, education, and age. Enabling factors included income, insurance, and regular source of care. Need factors included mental, physical, and oral health. Dependent variables included whether a respondent utilized dental services and number of visits. Results: More education, dental insurance, usual source of dental care, and poor oral health predicted a higher probability of having a dental visit. African Americans, Hispanics, those exposed to HIV through drug use or heterosexual contact, and those in poor physical health were less likely to have a dental visit. Of those who visited dental professionals, older persons, those with dental insurance, and those in worse oral health had more visits. African Americans and persons in poor mental health had fewer visits. Conclusions: Persons with more HIV-related symptoms and a diagnosis of AIDS have a greater need for dental care than those with fewer symptoms and without AIDS, but more pressing needs for physical and mental health services limit their access to dental services. Providers should better attend to the oral health needs of persons with HIV who are in poor physical and mental health. [source] EXPLORING RELATIONS BETWEEN TYPICAL AND MAXIMUM PERFORMANCE RATINGS AND THE FIVE FACTOR MODEL OF PERSONALITYPERSONNEL PSYCHOLOGY, Issue 4 2001ROBERT E. PLOYHART The study tests the distinction between typical and maximum criteria with ratings of transformational leadership performance, and examines whether the criterion-related validities of the five factor model differ for the two types of criteria. Using an East Asian military sample (n= 1,259) where multiple ratings of typical and maximum performance were obtained from different sources, we used structural equation modeling to test the typical/maximum performance distinction. Results found that typical and maximum performance are different latent constructs and that this distinction is present even after considering rating method factors (i.e., rater source, time). The importance of this distinction is shown by the fact that validities for the personality constructs were not equally predictive of both criteria: Openness was most predictive of maximum performance, Neuroticism was most predictive of typical performance, and Extroversion was predictive of both. By distinguishing typical from maximum performance constructs, relationships between personality and transformational leadership were found to be stronger than previous research suggested. [source] Mediating Pathways Explaining Psychosocial Functioning and Revictimization as Sequelae of Parental Violence Among Adolescent MothersAMERICAN JOURNAL OF ORTHOPSYCHIATRY, Issue 2 2009Taryn Lindhorst PhD Adolescent mothers are at high risk for negative life events, such as previous childhood physical abuse, impaired psychosocial functioning, and young adulthood revictimization. However, little is known about the potential pathways in these events; hence, little is known about opportunities for intervention. This study used structural equation modeling to investigate mediators of the effects of parental child abuse on later psychosocial functioning and revictimization (in the form of intimate partner violence and sexual violence) among adolescent mothers, with longitudinal data spanning 2.4 years. On psychological distress in the final time period, parental physical child abuse had an early and then maintained effect but also effects mediated by earlier psychological distress and revictimization. Psychological distress rather than substance use appeared as the primary psychosocial factor mediating the effects of parental violence on both future distress and revictimization. For prevention of further psychosocial impairment and revictimization, these findings indicate the need for early intervention with adolescent mothers who come from abusive families and who display higher levels of psychological distress. [source] Work Hours and Caseload as Predictors of Physician Burnout: The Mediating Effects by Perceived Workload and by AutonomyAPPLIED PSYCHOLOGY, Issue 4 2010Arie Shirom We tested a model in which perceived workload and autonomy were hypothesised to mediate the effects of work hours and caseload on physician burnout. The study was based on data provided by 890 specialists representing six medical specialties. We used structural equation modeling to test our hypotheses. Controlling for the effects of gender, seniority, and the specialists' academic affiliation, we found that the study data fit the hypothesised model,reflecting these hypotheses,quite well. As expected, workload predicted higher levels of global burnout and physical fatigue, while autonomy predicted lower levels of global burnout. Work hours and caseload predicted global burnout only indirectly, via their effects on either perceived workload or autonomy. These findings suggest that public policies, designed to reduce physician work hours in order to reduce burnout and improve patients' safety, should take into account physician perceived workload and autonomy. Nous avons mis à l'épreuve un modèle centré sur l'hypothèse selon laquelle la charge de travail perçue et l'autonomie régulaient l'impact de la durée du travail médical et administratif sur le burnout des médecins. La recherche a exploité des données fournies par 890 spécialistes relevant de six spécialités médicales. On a fait appel à une modélisation en équations structurales pour valider nos hypothèses. En contrôlant l'action du genre, de l'âge et du type de spécialité, il est apparu que les données correspondaient parfaitement au modèle hypothétique. Comme prévu, la charge de travail prédisait des niveaux plus élevés de burnout global et de fatigue physique, alors que l'autonomie débouchait sur des niveaux plus faibles de burnout global. La durée du travail ne prédisait qu'indirectement le burnout global, par l'entremise des retombées sur la charge de travail perçue et l'autonomie. Ces résultats montrent que la réglementation publique qui envisage de réduire le temps de travail des médecins dans le souci d'atténuer le burnout et d'améliorer la sécurité des malades devrait prendre en considération la charge de travail perçue et l'autonomie des médecins.
