The measurement of optimism and pessimism

Procedures employed in the development and validation of a new Optimism & Pessimism Scale are described, and information about test-retest reliability is reported. Internal consistency analyses and other data suggest that optimism and pessimism are not polar opposites and bring up questions about the intrerelatedness of the cognitive and affective realms. The magnitude of the correlation between pessimism and measures of anxiety suggests a link between this measure and the Negative Affectivity construct, and the potential relationships among optimism, pessimism, the Pollyanna Principle, and Positive and Negative Affect are discussed. Conceptually, it appears that optimism and pessimism may aid in psychological defense by helping to bind anxiety. This report was based on theses submitted separately by the second and third authors to the Division of Graduate Studies and Research of the University of Cincinnati, both in partial fulfillment of the requirements for the Master of Arts degree.

Worlds within worlds: a strategy for using interpretative phenomenological analysis with focus groups

There is increasing interest in applying interpretative phenomenological analysis (IPA) to focus group data and in developing appropriate strategies for doing so. These strategies should exploit the unique features of focus groups, which provide a rich canvas of experiences not seen in individual interviews, while remaining true to the personal, phenomenological perspective of IPA. We present a four-stage approach with specific group focused analytical strategies: looking for “groupness,” clustering reoccurring group interactions, identifying interactional relationships, and incorporating group elements into an analysis. These stages are illustrated with worked examples developed while working with data from focus groups of women with gynaecological cancer discussing a yoga intervention, and explain how these can enrich our understanding of participants’ lived experiences. This approach demonstrates a suggested framework for developing IPA themes from focus group data by analysing and interpreting the group setting. We discuss links to psychological concepts, potential applications and limitations. This empirically based methodology is presented as a practical guide for other researchers grappling with this type of data.     

Bicuspid Aortic Valve: a Review with Recommendations for Genetic Counseling

Bicuspid aortic valve (BAV) is the most common congenital heart defect and falls in the spectrum of left-sided heart defects, also known as left ventricular outflow tract obstructive (LVOTO) defects. BAV is often identified in otherwise healthy, asymptomatic individuals, but it is associated with serious long term health risks including progressive aortic valve disease (stenosis or regurgitation) and thoracic aortic aneurysm and dissection. BAV and other LVOTO defects have high heritability. Although recommendations for cardiac screening of BAV in at-risk relatives exist, there are no standard guidelines for providing genetic counseling to patients and families with BAV. This review describes current knowledge of BAV and associated aortopathy and provides guidance to genetic counselors involved in the care of patients and families with these malformations. The heritability of BAV and recommendations for screening are highlighted. While this review focuses specifically on BAV, the principles are applicable to counseling needs for other LVOTO defects.     

Selective spatial enhancement: Attentional spotlight size impacts spatial but not temporal perception

An important but often neglected aspect of attention is how changes in the attentional spotlight size impact perception. The zoom-lens model predicts that a small (“focal”) attentional spotlight enhances all aspects of perception relative to a larger (“diffuse” spotlight). However, based on the physiological properties of the two major classes of visual cells (magnocellular and parvocellular neurons) we predicted trade-offs in spatial and temporal acuity as a function of spotlight size. Contrary to both of these accounts, however, across two experiments we found that attentional spotlight size affected spatial acuity, such that spatial acuity was enhanced for a focal relative to a diffuse spotlight, whereas the same modulations in spotlight size had no impact on temporal acuity. This likely reflects the function of attention: to induce the high spatial resolution of the fovea in periphery, where spatial resolution is poor but temporal resolution is good. It is adaptive, therefore, for the attentional spotlight to enhance spatial acuity, whereas enhancing temporal acuity does not confer the same benefit.     

Beyond Abstinence: An Examination of Psychological Well-Being in Members of Narcotics Anonymous

While a growing body of literature supports the role of mutual help organizations in helping members achieve abstinence, fellowships other than Alcoholics Anonymous and outcomes beyond abstinence have been studied far less often. The current study examined recovery-related correlates of psychological well-being in a sample of Narcotics Anonymous (NA) members. Participants (N = 128) were self-identified NA members from across the United States who completed an online survey assessing an array of psychosocial outcomes. Hierarchical regression models assessed whether abstinence duration and other recovery-related variables accounted for significant incremental variance in psychological well-being, over and above several covariates. As a block, abstinence duration and the recovery predictors accounted for significant incremental variance in three of four psychological well-being domains. As a complement to studies on short-term benefits of mutual help organizations, these data suggest ongoing recovery involvement may be positively associated with subjective psychological well-being in NA members.     

Longing for Ex‐Partners out of Fear of Being Single

This research investigated whether people who fear being single have a more difficult time letting go of ex‐partners following a romantic breakup. Data were collected in a cross‐sectional study (N = 209, 64% women, M_age = 30 years old) as well as a 1‐month daily experience study of individuals who just went through a romantic breakup (N = 117, 44% women, M_age = 27 years old). Findings from both studies revealed that those with stronger fear of being single (Spielmann et al., 2013) reported greater longing for their ex‐partners. Pre‐ to post‐breakup analyses revealed that fear of being single increased after a breakup, regardless of who initiated the breakup. Within‐day analyses revealed that longing for an ex‐partner and attempts to renew the relationship were greater on days with stronger fear of being single. Lagged‐day analyses provided support for the conclusion that fear of being single increased longing and renewal attempts over time, but longing and renewal attempts did not influence fear of being single. These findings suggest that fear of being single is a particularly useful construct for understanding the romantic detachment process.     

Exploring the Relationship between Adolescent Activities and Choice of Graduate School Discipline: Implications for Creativity Development

The relationship between adolescent extra‐curricular activities and choice of graduate‐education field was examined among students from three fields of study, science (n = 12), art (n = 12), and education (n = 14), using qualitative and quantitative methods. Results of profile analysis indicated that the different majors participated in stereotypically varying activities when they were adolescents. Science majors generally participated in mathematics and science activities during adolescence. Art majors generally participated in theater and music activities, and education majors tended to have participated in social leadership and educational activities. Interviews with the participants supported these findings and provided a more comprehensive discussion of these tendencies. While in high school, the participants had many influences when determining a field of study. Using personal happiness as a guide, the participants chose activities and ultimately graduate‐level majors that reflected their interests. It was concluded that adolescent extra‐curricular activities are important in the development of interest in creatively talented individuals and may lead to graduate field selection.     

Identifiability of Diagnostic Classification Models

Diagnostic classification models (DCMs) are important statistical tools in cognitive diagnosis. In this paper, we consider the issue of their identifiability. In particular, we focus on one basic and popular model, the DINA model. We propose sufficient and necessary conditions under which the model parameters are identifiable from the data. The consequences, in terms of the consistency of parameter estimates, of fulfilling or failing to fulfill these conditions are illustrated via simulation. The results can be easily extended to the DINO model through the duality of the DINA and DINO models. Moreover, the proposed theoretical framework could be applied to study the identifiability issue of other DCMs.
