In recent years, a small but growing number of psychologists have begun to examine how the quality and stability of people's romantic relationships can be influenced by people outside of those relationships. Couples' friendships with those in their social networks appear to be particularly relevant determinants of what makes for a happy and lasting relationship. However, previous studies only have indirectly addressed underlying psychological mechanisms that may explain why friendships are beneficial for couples or how such friendships arise in the first place. This dissertation examines how friendships between couples form and potential implications for within-couple processes (e.g., the effects of friendships between couples on relationship quality within a couple). Pairs of unacquainted heterosexual couples in committed dating relationships were randomly assigned to one of two conditions where they engaged in a 45-minute interaction. In one condition, couples carried out self-disclosure tasks that gradually escalated in intensity; in the other condition, couples engaged in non-emotional small talk discussions. The procedure used was a modified version of the closeness induction task developed by Aron and colleagues (Aron, Melinat, Aron, Vallone, & Bator, 1997) to generate interpersonal closeness between individual strangers--in this case modified to generate closeness between couples. One day later and one month later, participants were asked to complete brief online follow-up measures to assess long-term effects of the experimental manipulation on perceptions of the other couple, feelings of closeness toward romantic partners, and whether or not they had contacted the other couple. Those in the high-disclosure condition felt closer to the couples they interacted with and closer to their own partners after the interaction compared to those in the small talk condition. Further, couples in the high-disclosure condition were significantly more likely than those in the small talk condition to contact and meet up with the other couple they had met in the study. Mediation analyses suggested several possible processes underlying these effects. Implications for studying the interplay of social networks and romantic relationships are discussed.

Case-control studies are the traditional ways in which foodborne enteric diseases are studied and outbreaks are investigated. This method has some significant limitations and biases for diseases with low efficiency reporting rates, such as Campylobacter, a common foodborne disease. Case-case methodologies have been explored for these studies but have been implemented without any clear strategy. This dissertation aims to first, determine the common risk factors for Campylobacter in Arizona using the traditional case-control study design, second, to systematically compare case-case studies to the more common case-control studies, and third, to simultaneously compare the results of a community outbreak of Campylobacter using both case-control and case-case study designs. Results from these studies identified some unique risk factors for routine Campylobacter infection in Arizona that will be used to enhance surveillance for the disease in the state. A systematic review of case-case studies used for enteric diseases found that there are specific recommendations that can be put into place in determining what comparison cases should be selected based on the primary aims and goals of the study. Finally, the results of the simultaneous case-case and case-control studies of a Campylobacter outbreak showed that these methods may work best in conjunction with one another and in doing so, the most accurate depiction of the source of infection can be determined.

This thesis attempted to determine if there were personality characteristic differences, as measured by the MMPI, between drug abusers who left treatment prematurely and drug abusers who remained in treatment for an extended period of time. In addition, it was attempted to determine if there were personality characteristic differences between drug abusers who entered treatment voluntarily and drug abusers who were required by law to obtain treatment.The MMPI protocols of 59 male drug abusers were divided into four groups and subjected to a two by two multivariate and Univariate Analysis of Variance. Results show that no significant differences were found between drug abusers admitted voluntarily and drug abusers admitted involuntarily. Significant differences were found between drug abusers who left treatment prematurely and drug abusers who remained in treatment for an extended period of time. Drug abusers remaining in treatment scored higher on scales Two, Seven, and Eight of the WI, while drug abusers who left treatment scored higher on the Lie scale. Suggestions for future research were made.

This dissertation is a qualitative case study of three homeschooling families. Because of the relative recentness of homeschooling as a widespread educational option for parents and because of the relatively few students participating in homeschooling, educators and others interested in this approach may benefit from the close qualitative consideration of homeschooling families of differing sizes, economic statuses, educational backgrounds, and other demographic differences. The primary research methodology for this dissertation is extensive and comprehensive interviews with three practicing homeschool families selected primarily because of their willingness to participate in the intensive interview process for this dissertation. The literature reviewed and the research questions considered include information about the estimated number of homeschooled students currently in the United States, the rationale behind parents’ choice to homeschool, a review of the basic demographics of homeschoolers, the legal and professional educators’ opinions about homeschooling, the instructional methods and curricular materials of homeschoolers, the academic achievement of homeschooled students, and the eventual college and career success of homeschooled students. The dissertation found that, while homeschooling parents would agree with much of the literature available to describe them, there were emphases and challenges to homeschooling that have not been fully studied and are applicable to individual families. / Department of Educational Leadership
