Habitual (i.e., average or typical) sleep duration and sleep efficiency vary widely by demographic characteristics, including age, gender, and racial/ethnic identity. Despite a wealth of studies on demographic patterns in habitual sleep, these results are often based on cross-sectional surveys, which ask participants to retrospectively recall their "typical" or "recent" sleep. Yet, sleep is a highly dynamic behavior and may fluctuate substantially from night-to-night. This intraindividual variability (IIV) in sleep/wake patterns can be captured a multitude of ways, most commonly by using formula-based calculations. Although there is growing attention on the importance of IIV in sleep, findings on demographic differences are still inconclusive, and there are no guidelines for typical values of IIV in sleep. The present study quantitatively synthesized 8 international data sets (N = 2847 participants, 29,832 total days of sleep data), focusing on examining age, gender, and racial/ethnic identity differences in IIV in sleep measured via sleep diaries, actigraphy, and electroencephalography. Sleep duration and sleep efficiency varied widely from night-to-night within people (duration: 64-119 minutes; efficiency: 5-8%). Different metrics of IIV were strongly correlated within and across sleep measurement types. Younger adults had more IIV in diary and actigraphy sleep duration. Gender differences in IIV in sleep …

There is an extensive amount of research on academic success and career development, but most of the literature has focused on the process of White participants. While some of the studies have examined samples from ethnic minority populations, the majority of studies use these populations as comparison groups, studying between-group differences as opposed to within-group differences. The literature is especially lacking in the area Latino academic success and career development. The current study examined how family and culture, specifically socioeconomic status, acculturation, and the quality of the parent-emerging adult relationship, influence the academic success and career development of Latino emerging adults. Eighty-three Latino undergraduate students ages 18 – 24 were recruited for participation in this study. Results indicated that valuing the role of work (career salience) significantly predicted the maturity and positivity of attitudes toward work (career maturity) in Latino emerging adults. Additionally, while family demographic and cultural variables did not seem to have a significant impact on academic success and career development, first-generation college student status, career salience, and conflict in the parent-emerging adult relationship lent some insight into the variation of levels of career maturity in a Latino sample. Furthermore, first-generation student status also impacted the relationship between …

In recent years, empirical research has consistently supported an association between susceptibility to affective illness and creativity at the level of eminent achievement and at the non-eminent, or "everyday creativity" level. Although this research has provided greater evidence for the existence of this link, it has simultaneously unearthed more questions about how and why such an association exists. The purpose of this research was twofold: first, to provide further analysis of the nature of the relationship between hypomanic traits and creativity by employing a longitudinal study to determine the extent to which inter-individual differences over time in creativity are predicted by hypomanic traits. Second, the purpose of the cross-sectional analysis in the present study was to further determine how developmental components such as age and expertise may help unravel the ways in which hypomanic traits contribute to creativity and to further describe inter-individual differences among these variables. The first hypothesis, which proposed that the direction of the relationship between hypomanic traits and creativity could be predicted, was not supported by these results. The second research hypothesis was partially supported: hypomanic traits predict creativity in the combined adolescent and older adult samples. However, upon further examination of the regression analyses, the …

Project SCORE: Life Skills for Future Success, is a structured, 20-lesson curriculum, designed to help students develop academic and life skills, as well as self-responsibility, commitment, optimism, respect, and excellence. The curriculum was presented during 36, 90-minute class periods over the fall semester of the students' freshmen year. The purpose of this study was to determine the effectiveness of Project SCORE at improving grades, learning strategies, self esteem and coping skills with freshmen students at an inner-city high school. In order to evaluate the program, students completed paper-pencil surveys at the beginning and end of the semester in which they were enrolled in the Project SCORE class. In addition, teachers completed evaluations on their perceptions of each student's peer relationships, classroom behavior, mood, and activity level. All teachers and students involved in the course were asked to complete an evaluation to determine their level of satisfaction with the course and areas in need of improvement. Lastly, information pertaining to grades, discipline and standardized test scores were used to determine the impact of SCORE. Participants were 333 9th grade students at a large 4A high school in Texas. Findings suggest that SCORE had a positive effect on coping resources, study skills …

There is a growing body of research on psychopathic traits in non-clinical populations. This emerging research has documented the prevalence of psychopathic traits in the general population and demonstrated that psychopathy has a similar latent structure as well as similar correlates (e.g., violent behavior, alcohol abuse, and lower intelligence) to forensic/offender samples. Relatedly, there is strong evidence insecure attachment patterns in adulthood are associated with many personality disorders, including psychopathy, but only a few studies have examined the relationship between attachment and psychopathic traits in non-clinical samples (albeit, convenience samples of college students). Thus, two aims of the current study are to: 1) describe and explore the manifestation and expression of psychopathic traits in a large, community-based sample and 2) examine associations between adult attachment disturbances and psychopathic traits in diverse sociodemographic subgroups. Using a cross-sectional design, results showed mean-level psychopathy factor score differences existed only when considering single sociodemographic factors (e.g., age), not an interaction of those factors. Psychopathy factor profiles were also consistent across groups, with higher levels of lifestyle followed by interpersonal, affective, and antisocial traits reported. Regarding the second aim, findings indicated support for the positive association between disturbed attachment patterns in adult relationships and psychopathic …

Breakups within emerging adulthood (EA) are associated with heightened distress because of individuals' tendency to be preoccupied by and prioritize romantic relationships. Global narrative scoring systems, such as Boals et al.'s meaning making (MM) and Feffer et al.'s interpersonal decentering, can be a useful for analyzing the activated cognitive processing in narratives about stressful events and have been linked to positive adjustment from those events. Attachment may moderate the benefits of processing a breakup. While avoidantly-attached people report lower breakup distress because of their tendency to suppress attachment-related thoughts and emotions, anxiously-attached individuals report prolonged distress due to their tendency to ruminate about the past relationship and to experience continued attachment to their ex-partner. The current study assessed the cross-sectional effects of MM and decentering on depression and breakup non-acceptance, as well as how attachment moderates the relationship between decentering and breakup adjustment. Results found higher MM was associated with higher depression and non-acceptance. More mature decentering was related to lower non-acceptance, but was unrelated to depression. Initial MM efforts may evoke more distress as individuals focus on distressing thoughts or emotions previously avoided. Initial decentering maturity may help with breakup adjustment as one effectively reflects on their own and …

The purpose of this study was to examine the extent to which levels of individuation and separation in adulthood would predict adjustment to the empty nest transition. Two-hundred and twenty-seven adults (M age = 48) who had experienced the empty nest within the last year completed a battery of scales assessing individuation from family of origin, spouse, and children as well as measures of adjustment, role strain, coping, and sex role attitudes. MANOVAS and hierarchical regression analyses suggested that levels of individuation from one's family of origin, spouse, and children differentially affect one's adjustment to, and coping with, the experience of launching of the youngest child from the home. Empty nest parents who are less differentiated from their own parents, from their spouses, and from their children reported a more negative impact of the empty nest in terms of more overall stress and role strain, more negative mood, and less life satisfaction than did empty nest parents who were more differentiated with regard to parents, spouse, and children. Results regarding the impact of individuation on empty nest adjustment regarding sex role attitudes were less clear cut, and may reflect cohort differences in work role opportunities for women and a parallel …

Having a secure attachment to God may act as a buffer against stress. Secure attachment to God has been positively associated with adaptive outcomes following stress, such as higher levels of stress-related growth and fewer maladaptive symptoms including depression, prolonged grief, and traumatic distress. However, relatively few studies have empirically tested the relationship between attachment to God and resilience and posttraumatic growth. Thus, the current study explored the potential associations and pathways through which attachment to God is associated with resilience and posttraumatic growth in a sample of 303 suddenly and/or traumatically bereaved individuals. The current study found that (a) God attachment avoidance is a unique negative predictor of resilience and posttraumatic growth even when controlling for adult attachment, (b) self-compassion and meaning-making mediate the association between God attachment anxiety and resilience/posttraumatic growth, (c) secure attachment to God is associated with higher levels of resilience than insecure attachment styles, but not with posttraumatic growth, and (d) an increased number of secondary losses is associated with lower levels of resilience. I conclude by discussing my findings in light of the extant literature on attachment to God, resilience, and posttraumatic growth. By better understanding attachment to God and how it may relate …

The purpose of this study was to explore the relationship of separation-individuation during late adolescence and obstacles to career decision making.

Physical activity has been demonstrated in the literature as an effective way to reduce the risk for development of chronic disease. The Transtheoretical Model (TTM) of behavior change has been developed as a means to predict and facilitate movement into healthier lifestyle behaviors. The model is centered on "stages of change", which describe a continuum of readiness to engage in a health behavior change. Stages contain temporal, qualitative, and quantitative characteristics. This was a six-month study that evaluated the effectiveness of stage-matched (theorized to be pertaining only to the maintenance stage of change) vs. generic (theorized to be pertaining to anyone, regardless of stage) newsletters in assisting subjects to attain the Maintenance stage of change. It also sought to identify further qualitative characteristics that can differentiate between the Action and Maintenance stages of change. Results indicated that monthly stage-matched newsletters were no more effective in helping subjects reaching Maintenance than were the generic newsletters. Exerciser self-schema was related to stages of change, but those relationships differed from baseline to six-month follow-up, indicating development of exerciser self-schema during the study period. Implications of this are discussed. Other concepts discussed included "structure" of change process, in that three new scores were developed …
