Young adulthood is a crucial period for identity development, and an unclear sense of identity has been associated with deleterious psychological and social outcomes (Kroger & Marcia, 2011). Young adults have also identified self-sufficiency, including financial independence, as an essential aspect associated with attaining adulthood (Arnett, 2000). However, current realities such as global economic uncertainty and a shift toward greater personal responsibility for financial security may threaten the successful attainment of these essential goals (Furstenberg, Rumbaut, & Settersten, 2005). Hence, I explored identity formation (Erikson, 1950, 1968) in the domain of finance. Four socialization factors (perceived parental SES, parental financial communication, formal financial education, and high school work experience) and three beliefs (attitudes, subjective norms, and perceived behavioral control) were used to predict financial identity (achievement, foreclosure, moratorium, and diffusion) in a sample of college students (N = 2,098) who were surveyed at two time points approximately 2.5 years apart. Four models were tested using structural equation modeling (SEM). First, using crossectional data, I tested the extent to which socialization factors and financial beliefs predicted financial identity. I found support for 79% of the hypothesized associations between the variables. Second, using crossectional data, I examined the degree to which financial beliefs mediated the association between socialization factors and financial identity. Findings indicated that financial beliefs partially mediated the association between parental financial communication and financial identity. Third, using longitudinal data, Time 1 (T1) socialization factors and T1 beliefs were used to predict Time 2 (T2) financial identity. As expected, T1 financial identity was the most robust predictor of T2 financial identity. After controlling for T1 financial identity, T1 variables were most predictive of changes in T2 foreclosure: Increases in foreclosure were predicted by perceived parental SES, parental communication, formal education, and subjective norms. Finally, T1 financial beliefs were allowed to mediate the association between T1 socialization factors and T2 financial identity. I found no evidence of mediation using longitudinal data. Findings from this study suggest that identity formation within the financial domain is consistent with identity formation in other recognized identity domains.

Shared social responsibility (SSR) has been increasingly promoted in sustainability research. While conceptual development has been expanded, empirical developments are still in their infancy. Extant SSR literature acknowledges that entities like industry, governments, consumers, and others must accept responsibility for achieving a common goal. However, a basic understanding of how consumers view this responsibility in the shared setting is lacking. Since collaborative efforts towards sustainability may be strategically more effective than individual efforts, this research investigates SSR from the consumers' perspective in order to determine how responsibility is assigned to the various entities involved in a specific form of sustainability, "green" product consumption. Perceptions of responsibility may influence future sustainability-minded consumer behavior; hence, this research offers relevant contributions for understanding the shared social dynamic. Utilizing elements of attribution theory, equity theory, and diffusion of responsibility, this research examined how ability, perceived consumer effectiveness, perceptions of equity, and group size influence consumer attribution of responsibility for future "green" product consumption. Three experiments were conducted; the first two used an online scenario-based approach while the third was administered primarily at the University of Arizona. Data was analyzed using various statistical techniques, including multivariate analysis of variance to address the study hypotheses. Results established that consumers share responsibility for future "green" product consumption with corporations, government, and other consumers - but this responsibility is not shared evenly. Under most of the conditions evaluated, corporations, and government to a lesser degree, were attributed significantly more responsibility than consumers assigned themselves. The amount of effort required to use a "green" product, ability to positively change the environment, and equity of an interaction between a consumer and a manufacturer did not affect consumer attribution of responsibility. Group size had some impact, such that consumers who were not made explicitly aware of being in a group and those interacting with one other entity evenly shared responsibility for future "green" product consumption with the others involved. Consumers in larger groups assigned more responsibility to corporations than to themselves. Social loafing was determined not to be a factor in how consumers assigned responsibility in groups of various sizes.

The Two-Step Flow of Communication suggests that opinion leaders have a greater impact on consumers' product choices and decisions than marketers. With the advent of the Internet and e-commerce, many consumer researchers expanded the study of opinion leadership to incorporate electronic Word-of-Mouth behavior (eWOM) into the Two-Step Flow of Communication. Yet, with the recent and increasing prominence of social media, there appears to be a gap within the opinion leadership literature. Several studies have examined how the Internet and social media empower opinion leaders to instantaneously influence large crowds with eWOM. Marginally few studies, however, have considered how the production of user-generated content (UGC) among opinion leaders can further expand their peer influence. Furthermore, emergent research illustrates that social media is transforming into an enclave for celebrity culture, wherein celebrities use social media to invoke gossip and fantasy in consumers. These technological and cultural shifts within the Internet and social media necessitate an understanding of how UGC, social media and celebrity culture fit within the Two-Step Flow of Communication. In order to address these gaps, the current study probed the relationships amongst parasocial interaction, opinion leadership and willingness to participate in UGC and eWOM. Specifically, parasocial interaction is a history of interactions between a consumer and celebrity that manifest into a fantasized, personal relationship. Relevant hypotheses were developed and used to construct a theoretical model. Data were collected from a nationally representative sample (n = 555) and a Structural Equation Model was subsequently run to test the hypotheses. The findings suggest that social values, knowledge and parasocial interaction are positively related to opinion leadership. In turn, opinion leadership is positively related to willingness to participate in UGC and eWOM. Parasocial interaction, too, is positively related to willingness to participate in UGC and eWOM. A mediation effect was supported whereby opinion leadership significantly mediates the relationship between parasocial interaction and UGC, but not eWOM. The production of UGC is shown to be dependent upon parasocial interaction and opinion leadership. Nonetheless, eWOM does not seem to necessitate opinion leadership and can be produced directly from parasocial interactions.

Mexican-origin adolescent girls have some of the highest rates of unplanned teen pregnancy and births in the United States. Family ecological and feminist perspectives indicate that gender and sexual socialization processes contribute to girls' ability to promote their sexual health, yet little is known about how Mexican-origin girls develop sexual agency. In this culture, mothers are a primary socializing agent about sexuality in the family, and this study examined how mother-daughter sexual communication fostered or inhibited girls' sexual agency. The narrative method "scaffolded interviewing" was used to facilitate open talk about sexuality. Interviews were conducted with 25 girls ages 15-17 and separate interviews with mothers in a southwestern city, with a pilot study first conducted to refine the interview script. Mothers and daughters were asked reciprocal questions about what girls learned about sexuality from mothers and other contexts. The Listening Guide, a voice-based relational approach, was used to interpret the data. Analysis suggested that girls whose mothers provided more open and comprehensive sexual communication, and talked to them before puberty, felt more agentic to assert their needs for sexual safety. Girls who had infrequent, content-limited communication with mothers felt less able to manage fear-based school sex education messages and peer sexual exposure. Analysis of concordance between mothers' and daughters' narratives showed that different perceptions of what constitutes sex talk and sexual autonomy inhibited daughters' disclosure to mothers about sexual concerns. These findings suggest that mother-daughter relationships are critical for sexual health promotion. Implications for educators, practitioners, and families are discussed.

Adolescence is a unique time during the human lifespan, where children develop into reproductively competent adults, and many behavioral and psychological changes develop. The goal of this dissertation is to examine the underlying functions related to the emergence of risky adolescent "behaviors," broadly defined to include both physical risks (e.g., drinking or physical fighting) and psychological risks (e.g., anxious or depressive symptoms). In this paper I (1) present a manuscript reviewing and synthesizing the relevant evolutionary theories, which bears testable hypotheses regarding sex differences in risky adolescent behavior, and (2) empirically assess these predictions in two separate but theoretically and conceptually related studies that test for theoretically-based hypothesized relations: one specific to males, one to females. Specifically, I test the proposition that males should be more likely to engage in physically risky behavior than females, and that females should be more likely to engage in affective risks (assessed as sensitivity to social evaluation). These hypotheses are generally supported, but shed light on important environmental factors that are associated with the prevalence of risk-taking, including the degree of closeness within the family, timing of pubertal development, and social status. In general, an early pubertal development and low social status are associated with risk-taking, while closeness to family buffers against the likelihood of engaging in later risky behaviors.

The peer group is a dynamic context within which children and adolescents have a wide range of experiences, both positive and negative. Friendships provide support and a sense of belonging; however, friendships can also be contexts within which competition and aggression occur. During childhood and adolescence, aggression and victimization are likely to occur in the school context and in situations where several members of the peer group are present and sometimes actively (or passively) participating. In the seminal work related to bullying as a group process, Salmivalli and colleagues identified distinct roles that children take when enacting aggression (Salmivalli et al., 1996). Salmivalli's work, in the area of participant roles, however, has focused on overt bullying, a specific subtype of aggression which has a specific meaning within the peer relations literature. To date, the participant roles have not been measured within the context of overt and relational aggression. The purpose of the present study is to examine the psychometric properties of the Overt Aggression Participant Role Scale (OAPRS) and the Relational Aggression Participant Role Scale (RAPRS), two new scales designed by the author, to measure the aggressor, assistant, reinforcer, defender, outsider, and victim roles during acts aggression, as opposed to bullying. Additional goals include: 1) exploring the associations among the roles, 2) examining measurement equivalence across gender and grade level, and 3) exploring associations of the participant roles with measures of sociometric status and depressive symptoms. Findings point toward the psychometric properties of the two scales being quite robust. The data fit the 12 factor model and the scales measure the constructs equivalently across gender and three grade groups. The aggressor, assistant, and reinforcer roles were strongly associated as were the aggressor and victim roles. Several relational roles were highly overlapping, suggesting reciprocity of roles. Few meaningful gender or grade level differences were found resulting in more similarity in the overt and relational roles than differences. The outsider role was the only role not associated with depressive symptoms. Implications for prevention and intervention are discussed.

Researchers must consider the role of context when examining the behavior and characteristics of an individual. An individual must alter development, characteristics, and behavior, to adequately meet the challenges presented within their ecology. The following dissertation presents three manuscripts that examine individual differences while considering the role ecological (spatial) and developmental (temporal) context plays on the individual. Each paper utilizes Life History Theory to examine and to integrate the study findings into a cohesive framework. Life history theory is an evolutionary-developmental theory that focuses on how allocation of bioenergetic and material resources to different developmental facets will have long-term implications for behavior, traits, and health. Each paper collectively highlights key contextual factors throughout the lifespan and seeks to understand how life history strategies emerge. Study I examined the role mother's behavior had on the development of the child unpredictability schema (i.e., worldview where children view their environment and others as unreliable). The study included 65 children and their mothers. Results revealed that child unpredictability schema was predicted by mother's mating and parental effort. A quadratic effect was also found, whereby child unpredictability schema became constant at lower levels of parental effort. Study II utilized retrospective reports of childhood parental effort from extended kin family, positive emotional environment, and traditional social values from a sample of 200 Mexican and Costa Rican college students. High levels of childcare assistance from patrilineal and matrilineal kin were associated with more positive family environment, and the association was partially mediated between kin care and slow life history. Positive associations were also found between matrilineal kin childcare and traditional Latin social values. Study III utilized a nationally-representative, all-female sample to test whether higher reproductive effort increases physical/mental deterioration in women. Results reveal that reproductive effort and illness were mediated by both antioxidant defenses and inflammation. The results of the three studies broadly support hypotheses generated from Life History Theory. Contextual factors during key developmental stages have an impact on how an individual will allocate time and bioenergetic resources - thus contributing to specific behavioral life history strategies.

The goal of this dissertation is to examine minority stress in the lives of gay and lesbian individuals and couples. To do this I conducted three separate, but empirically and conceptually related studies using data from 68 self-identified gay men and lesbians. Of these, 38 participants were coupled (n = 19 couples). All three studies were informed by minority stress theory. In the first study I examined individual (N = 68) and partner (n = 38) correlates and associations with concern for safety because of sexual orientation and harassment because of sexual orientation. Comfort with homosexuality was the strongest negative predictor of concern for safety because of sexual orientation. Further, involvement with gay related activities was found to be the strongest positive predictor of harassment because of sexual orientation. In the next two studies I examined the daily influence of minority stress for same-sex couples (n = 19). In the second study I examined how daily public displays (PDA) of affection are associated with daily relationship satisfaction, daily concern for safety because of sexual orientation, and daily harassment because of sexual orientation. I found daily PDA to be positively associated with concurrent and lagged relationship satisfaction, positively associated with concurrent and lagged concern for safety, and concurrent, lagged, and prospective increases in harassment because of sexual orientation. In the third and final study I examined the moderating effect of daily relationship satisfaction on the relationships between daily concern for safety and harassment in predicting daily physical health and well-being. I find that daily concern for safety and harassment are not associated with daily physical health suggesting that the negative effects of minority stress on physical health are more cumulative and do not fluctuate from day-to-day. I also find that daily relationship satisfaction does moderate the relationship between daily concern for safety and harassment and their daily well-being in unexpected ways. Collectively, this dissertation illustrates the complex influence of minority stress in the lives of gay and lesbian individuals and couples in two ways: first, as it pertains to how personal characteristics and behaviors (e.g. involvement with gay related activities and engagement in PDA) are associated with minority stress overall and on a daily basis; second, by illustrating the daily influence of minority stress on daily physical health and well-being. In conclusion, in these studies I highlight the complexity of life and how minority stress, stress that is unique to gay men and lesbian individuals and couples, complicates otherwise beneficial behaviors. Further, I illustrate the long and short term ramifications minority stress has on gay men and lesbian individuals and couples.

Estimates suggest that 40% of the food grown in the United States ends up in landfills. Household losses are the highest contributor to volume of waste overall, and individual households are estimated to discard around 15% of their total acquired food inventory. Consumers are generally waste averse and a vast majority have been shown to object to wasting food in particular, yet almost all consumers discard a substantial volume of potentially edible food each year. This exploratory qualitative study sought to uncover underlying psychological mechanisms behind this discrepancy between attitude and behavior by exploring the decision-making processes that consumers engage in as they acquire, prepare, consume and discard food. By exploring the patterns of thinking that shape household provisioning practices through an initial in-depth interview, a two-week long household food diary and a follow-up interview with 17 diverse consumers, a grounded theory emerged to explain this counter-intuitive behavior pattern. Extending research from behavioral economics and decision making literature, data from this study suggests the following: 1) people evaluate cost of goods based on incomplete value estimations that fail to account for the costs associated with discarding potentially edible foods; 2) costs associated with the act of shopping are salient and encourage less frequent provisioning trips; 3) people do not adequately account for costs associated with overbuying and storing food; and 4) consumer strategies aimed at maximize efficiency in food acquisition through less frequent shopping trips may actually result in increased inefficiency in the form of greater waste and higher overall cost of goods. Based on emergent findings, a strategy for waste avoidance is presented along with managerial implications.

Counterfeit consumption is becoming widespread, developing into a problem of international significance. In an attempt to develop a refined understanding of the motivations and decision-making processes of consumers' deliberate counterfeit-consumption behavior, this empirical study not only integrates the theory of planned behavior and insights from self-regulatory theories, but also extends these theories by re-conceptualizing the relationships among key constructs with the inclusion of action desire. This research also introduces and integrates a new construct, namely consumers' Perceived Counterfeit Detection (PCD) by important others.Using a combination of qualitative and quantitative methods consisting of in-depth interviews and a self-administered paper questionnaire, this research empirically tested a proposed goal-striving model for deliberate counterfeit-consumption behavior, using structural equations modeling. Results demonstrated PCD's existence and supported a refined goal-striving model, based upon which effective strategies to decrease consumer's counterfeit consumption are discussed.
