Adolescent Substance Use Patterns: Testing A Multidimensional Sociogenic Model, Eric O. Johnson

Dissertations

This dissertation begins with the understanding that behavior is a product of a variegated and complex web of social factors. Bringing this approach to the subfield of adolescent substance use, both substance use itself (alcohol, cigarettes and a broad range of illicit drugs) and the factors that influence such use are viewed as existing within the complex of demographic/structural, social contextual, attitudinal, and behavioral layers of adolescents' social worlds.

The Patterns of Adolescent Substance Use Typology, developed by Stanley S. Robin and me (1992a), is used to categories the overall level and kind of substance use, over time, that adolescents …

The Link Between Psychosocial Factors And Coronary Heart Disease: A Possible Neuroendocrine Mechanism, Sheila Wang

Dissertations

Coronary heart disease continues to be the leading cause of death in the affluent world. Despite identification of several risk factors for coronary heart disease (age, sex, lipoprotein profile, hypertension, diabetes, cigarette smoking, obesity), a significant amount of variability associated with the incidence of coronary heart disease cannot be explained solely on the basis of these risk factors. The contribution of psychosocial factors to the development of coronary heart disease (type A behavior, social isolation, traumatic events, unstable social conditions) continues to be a promising area of investigation. However, a biochemical pathway linking psychosocial factors to coronary heart disease remains …

There are, however, no validated stress measures applicable to the Hispanic community as a whole.

The purpose of this study was twofold: First, to translate into Spanish the Daily Stress Inventory (DSI) (Brantley & Jones, 1989) and to validate the translation by conducting a correlation study between the the Spanish and the English versions. …

Preferred Motivators For Previously Incarcerated Criminals, Selma R. Massey

Dissertations

The issue of motivators has been studied by a number of researchers and practitioners in education, sociology, and psychology. Many of these studies have linked motivators to behavior (Coffey, 1987; Coleman, 1987; Gellerman, 1963; Gould & Sigall, 1977). Questions remain, however, as to which motivators are viewed by actors themselves as the most preferred influencers of behavior. The primary objective of the research was to compare the rank order of the most frequently cited motivators identified in research studies and the rank order of the most preferred motivators as perceived by previously incarcerated criminal respondents. A secondary objective was to …

Caring For Dementing And Nondementing Chronically Ill Elderly In Belgium: Modeling Salutogenic And Pathogenic Processes, Timothy John Gallagher

Dissertations

The predominant model in the study of stress and disease has been identified as the pathogenic orientation. The underlying assumption of this orientation is that stress is, by nature, disease causing. An alternative model is the salutogenic orientation (Antonovsky, 1979). Researchers using the salutogenic approach are concerned with explaining the origins of health. In the present study, a sample of Flemish caregivers {N = 126) to persons with chronic dementing and nondementing disorders is examined in order to detail how sense of coherence (a measure of personality disposition), the nature of patient pathology, demographic characteristics, coping resources, and perceived negative …

Requisite Managerial Leadership Behaviors: A Diagnostic Role-Set Study Of Executives Within A Fortune 500 Corporation, Prudence Labeach Pollard

Dissertations

This study examined the extent to which executives' perceptions of their managerial leadership behaviors compare to their role-set's perceptions of the same behaviors. Additionally, the difference between the perceptions was related to the identified requisite executive skills and behaviors. Executives and their role-set were informed of the developmental purpose for which they were making the ratings. An executive's role-set is comprised of superior, peers, and subordinates, who spend significant amounts of time with the executive and are best able to observe the executive's behavior.

The Management Skills Profile (MSP) was used to investigate self and each role-set group's ratings of …
