The purpose of this study was twofold: to test the Competence Model for Normal Aging and to generate valid and reliable indices of mental health outcomes in elderly clients. A correlational descriptive design accommodated the psychometric assessment of the instruments with a causal modeling methodology. The relationship between competence and self-esteem was the primary focus. Theoretical model testing was used to test the causal relationships between competence and three estimates of cognition: causal attributions, self-efficacy, and value. Associated demographic variables, age, and gender, were included in the model. Well elders (n = 137) living independently in Tucson participated in the study by completing 9 instruments within a 40-minute testing period. The mean age of the group was 73 (sd = 7.9). A quarter of the sample was at least 80 years old. All participants were caucasian, with more than twice the number of females than males. Most participants were married or widowed. The instruments met validity and reliability criteria in varying degrees. Hypothesis 1 was supported in both the separate success and failure models and the total sample theoretical model. Self-efficacy (β = .48) and value (β = .27) predicted competence (R² = .42). The social subscale of competence was strongly predicted by the same variables (β = .53, β = .26; R² = .39). The same predictors were evident in the total sample theoretical model (β = .52; β = .25; R² = .38). Hypothesis 2 was partially supported. Self-efficacy predicted total competence (β = .49; R² = .30) and the social dimension of competence (β = .59; R² = .32). Hypothesis 2 was minimally supported in the total sample theoretical model by self-efficacy (β = .29) predicting the social component of competence (R² = .44). Hypothesis 3 was most strongly supported. Competence predicted self-esteem under multiple conditions (βs averaged .43). The associated demographic and gender variables made minimal contributions to the model, except under failure conditions. Not being married and being a male negatively impacted upon competence (β = -.21; β = -.39; R² = .31). Both theoretical and empirical model results have similar explained variances. The theoretical model provided key information regarding the process of self-esteem, and the empirical model provided a guide for clinicians to measure mental health outcomes.

Falls among elderly people have been identified as a significant and serious medical problem confronting a growing number of older people. Falls have been found to be a leading cause of disability, distress, admission to supervised care and death among older persons that pose a serious problem to public health. The purpose of this study was to determine the prevalence of and risk factors for falls in the community-dwelling elderly persons in the Umutara province of Rwanda.

Compared to the general population, diabetic patients experience a higher prevalence of depression, which can often exacerbate diabetic symptoms and complicate treatment. Studies show that religion is associated with both better physical health and better psychological functioning; however, studies incorporating religion and depression among diabetic individuals are scarce. The present study addressed this gap in the literature by examining archival data from the 2008 and 2010 data waves of the Health and Retirement Study (HRS). Cross-sectional findings confirmed that stronger religiosity was positively correlated with perceived diabetes control and positive diabetes change, and negatively correlated with total number of depressive symptoms and total number of weeks depressed. Longitudinal findings confirmed that stronger religiosity in 2008 was positively correlated with perceived diabetes change in 2010 and negatively correlated with total number of depressive symptoms in 2010. Logistic regression and multiple regression analyses were performed to test four moderation models. Results showed that religiosity significantly moderated the relationship between perceived diabetes control and total number of weeks depressed. More specifically, for diabetics with low levels of religiosity, whether they believed their diabetes was under control or not did not make a significant difference in the total number of weeks depressed. However, high levels of religiosity served as a buffer against the duration of depressive symptoms but only for diabetics who perceived to have their diabetes under control. Understanding how these constructs jointly influence diabetes management and psychological functioning is critical in that medical professionals may utilize such knowledge to enhance treatment outcomes.

This thesis examines ideas about old age in four anecdotes and their illustrations from the 1334 illustrated Mamluk volume of al-Hariri's (1054-1122) Maqamat in the context of early (1250-1382) Mamluk society. The Maqamat contains fifty short anecdotes with a common plot format and two main characters. In each anecdote, the narrator al-Harith relates an adventure of the hero Abu Zayd, an elderly beggar who travels throughout the medieval Islamic Middle East. Using his talent as an orator, Abu Zayd draws people together in a public place, performs an eloquent speech, and is rewarded with money and goods. Ideas about the status of old age in Muslim society originate in the Qur 'an and hadith. Attitudes about the elderly are expressed in other selected texts and in painting (frescoes and manuscript illustration). In the 1334 Mamluk volume, Maqamat illustrations either enhance the text or function independently of the text. Images portray old age as a vehicle for the transmission of knowledge and authority in the social roles of literary scholar, judge, religious leader, and teacher.
