Students frequently request concept-list study guides prior to exams, but the benefits of instructors providing such resources are unclear. Research on memory and comprehension has suggested that some challenges in learning are associated with benefits to performance. In the context of an introductory psychology course, a study was conducted to investigate the impact of providing a concept-list study guide on exam performance, as opposed to having students create a study guide. Additionally, student preferences for various types of study guides were examined. Results indicated that although students greatly prefer that the instructors provide a study guide (as opposed to making their own), providing a concept-list study guide resulted in poorer exam performance. These results call for future research on the influence of study guides on student performance.

Wikipedia is a widely used online reference work which cites hundreds of thousands of scientific articles across its entries. The quality of these citations has not been previously measured, and such measurements have a bearing on the reliability and quality of the scientific portions of this reference work. Using a novel technique, a massive database of qualitatively described citations, and machine learning algorithms, we analyzed 1,923,575 Wikipedia articles which cited a total of 824,298 scientific articles, and found that most scientific articles (57%) are uncited or untested by subsequent studies, while the remainder show a wide variability in contradicting or supporting evidence (2-41%). Additionally, we analyzed 51,804,643 scientific articles from journals indexed in the Web of Science and found that most (85%) were uncited or untested by subsequent studies, while the remainder show a wide variability in contradicting or supporting evidence (1-14%).

A common cultural norm in committed relationships is that of sexual exclusiveness. When this norm is violated, those involved are often perceived negatively. Recently, a website facilitating extradyadic relationships, AshleyMadison.com (AM), was hacked, and the personal information of the members was illegally disseminated. As a result of the large amount of accompanying media coverage, AM users have been negatively perceived and even openly mocked. The current study explored potential predictors for the negative perceptions (i.e. demonisation) of AM users using a large online sample. In a predominantly exploratory study, myriad variables were examined from both outside (e.g. just world belief) and inside the psychosexual (e.g. sociosexuality) literature. The findings indicate that the predictors of jealousy and sexual guilt both positively predict demonisation of AM users, above and beyond the other individual difference variables.

Shnabel and Nadler (2008) assessed a needs-based model of reconciliation suggesting that in conflicts, victims and perpetrators have different psychological needs that when satisfied increase the chances of reconciliation. For instance, Shnabel and Nadler found that after a conflict, perpetrators indicated that they had a need for social acceptance and were more likely to reconcile after their sense of social acceptance was restored, whereas victims indicated that they had a need for power and were more likely to reconcile after their sense of power was restored. Gilbert (2016), as a part of the Reproducibility Project: Psychology (RP:P), attempted to replicate these findings using different study materials but did not find support for the original effect. In an attempt to reconcile these discrepant findings, we conducted two new sets of replications—one using the RP:P protocol and another using modified materials meant to be more relatable to undergraduate participants. Teams from eight universities contributed to data collection ( N = 2,738). We did find moderation by protocol; the focal interaction from the revised protocol, but not from the RP:P protocol, replicated the interaction in the original study. We discuss differences in, and possible explanations for, the patterns of results across protocols.

Social support is the subject of much research, but comparatively little attention has been paid to support seeking. Moreover, what research exists on support seeking has primarily addressed in-person support seeking, despite the proliferation of new support venues (e.g., Facebook, websites, etc.). This article uses a daily diary methodology to examine the support-seeking behavior men (N = 41) and women (N = 97) exhibit in response to various types of stressors. Results indicate that (a) in-person support seeking remains the most popular form; (b) compared to achievement stressors, social stressors are more likely to result in emotional support seeking rather than instrumental support seeking; and (c) men may engage in more support seeking than has been previously suggested by the literature, particularly in electronic venues.

The relationship between religion and sexual satisfaction has long been debated. Oftentimes, previous research on the relationship between these two constructs has been directly contradictory. The current study sought to provide more detail, or perhaps clarify the way that religiosity may relate to sexual satisfaction. Past studies have shown that high religiosity is connected to lower sexual activity, lower desires, and more conservative values. Thus, the current study examined sexual guilt, resulting from sensitivity to internalized religious beliefs and teachings, as a potential mediator between the two constructs. Participants completed an online questionnaire that included measures of religious identification and internalization, sexual satisfaction, and sex guilt. Results suggest that sex guilt mediates the rela- tionship between religiosity and sexual satisfaction for unmarried individuals, but not for married individuals. We suggest calling this finding the sacred bed phe- nomenon because the difference between the models for married and unmarried samples may be due to a belief in the sacred marital bed.

The current study investigated a model explaining sexual assault victims’ severity of trauma symptoms that incorporated multiple stigma constructs. Integrating the sexual assault literature with the stigma literature, this study sought to better understand trauma-related outcomes of sexual assault by examining three levels of stigma—cultural, social, and self. Results showed self-stigma was significantly and positively related to trauma symptom severity. Thus, results revealed that the internalized aspect of stigma served as a mechanism in the relation between sexual assault severity and increased levels of trauma symptom severity, highlighting the importance of assessing self-stigma in women reporting sexual assault experiences.

The current crisis of veracity in biomedical research is enabled by the lack of publicly accessible information on whether the reported scientific claims are valid. One approach to solve this problem is to replicate previous studies by specialized reproducibility centers. However, this approach is costly or unaffordable and raises a number of yet to be resolved concerns that question its effectiveness and validity. We propose to use an approach that yields a simple numerical measure of veracity, the R-factor, by summarizing the outcomes of already published studies that have attempted to test a claim. The R-factor of an investigator, a journal, or an institution would be the average of the R-factors of the claims they reported. We illustrate this approach using three studies recently tested by a replication initiative, compare the results, and discuss how using the R-factor can help improve the veracity of scientific research.

Fanconi anaemia (FA) is a rare genetic disorder associated with bone marrow failure (BMF), congenital anomalies and cancer susceptibility. Stem cell transplantation (SCT) offers a potential cure for BMF or leukaemia, but incurs substantial risks. Little is known about factors influencing SCT decision making.The study objective was to explore factors influencing patients' with FA and family members' decision making about SCT.Using a mixed-methods exploratory design, we surveyed US and Canadian patients with FA and family members who were offered SCT.Closed-ended survey items measured respondents' beliefs about the necessity, risks and concerns regarding SCT; multivariable logistic regression was used to examine the association between these factors and the decision to undergo SCT. Open-ended survey items measured respondents' perceptions of factors important to the SCT decision; qualitative analysis was used to identify emergent themes.The decision to undergo SCT was significantly associated with greater perceived necessity (OR = 2.81, P = 0.004) and lower concern about harms of SCT (OR = 0.31, P = 0.03). Qualitative analysis revealed a perceived lack of choice among respondents regarding the use of SCT, which was related to physician influence and respondent concerns about patients' quality of life.Overall, study results emphasize the importance of the delicate interplay between provider recommendation of a medical procedure and patient/parental perceptions and decision making. Findings can help providers understand the need to acknowledge family members' perceptions of SCT decision making and offer a comprehensive discussion of the necessity, risks, benefits and potential outcomes.

In recent years, policy debates in the United States have focused heavily on rising healthcare costs and what measures can be taken to ensure greater provision of healthcare to individuals of limited means. Much of the rhetoric on this subject has taken on an explicitly moral character, and one common sentiment is that healthcare is or should be viewed as a basic human right. However, the notion of a right to healthcare has not been well articulated, and critics have failed to distinguish between legal and moral rights. Additionally, there are numerous problems inherent to viewing healthcare as a basic human right-many of which are in direct conflict with distinctly American conceptualizations of rights. The present paper reviews the debate over “rights”-both legal and natural-to healthcare, and argues that problems associated with natural rights arguments render them severely compromised. Instead, market systems commonly accepted in American society may be better suited to reducing healthcare costs and increasing access to services in the United States.

Abstract 3207 Poster Board III-144 Introduction Fanconi anemia (FA) is a primarily autosomal recessive, genetically heterogeneous disorder of chromosomal instability associated with congenital anomalies, cancer susceptibility, and progressive bone marrow failure. Currently, hematopoietic stem-cell transplantation (SCT) is the only treatment that will restore normal hematopoeisis; transplant protocols and recommendations are modified routinely due to challenges with severe toxicities in pre-transplantation conditioning regimens as well as complications related to acute and chronic graft-versus-host disease. SCT may also increase the risk of subsequent solid tumors, particularly head and neck squamous cell carcinomas, and has a significant mortality rate among FA patients. Given these potential harms, the decision-making process about SCT in FA patients is complex. The purpose of this study was to survey FA patients and their families in the United States (USA) and Canada to gain a better understanding of the factors that influence their decisions about SCT. We explored how perceptions of the need and associated risks of SCT influence the choice to undergo SCT. Patients and Methods Individuals who were members of the FA family organizations in the USA and Canada were sent a self-report survey via a two-phase blinded mailing whereby non-responders from the first mailing were sent a second questionnaire. Parents and patients were queried separately. A single respondent was selected to represent each affected individual, according to the following selection hierarchy: mother as primary respondent, followed by father, adult patient, and spouse/significant other. Survey items about decision-making were adapted from The Beliefs about Medicines Questionnaire (Horne, Weinman, & Hankins, 1999) which assesses respondents' beliefs about the necessity, associated risks, and concerns regarding a medical intervention, in this case SCT. Each of the three predictor variables (necessity, risk and concern) was measured by core items rated on a 4-point Likert scale. The necessity subscale was measured by core items which evaluated the respondents' perception of the medical need for SCT. The risk subscale measured respondents' perceived likelihood that the patient would suffer from: physical or emotional side-effects of SCT, liver disease, infection, graft-versus-host-disease, infertility, post-SCT cancer, post-SCT leukemia, graft rejection, death, or hazards to future offspring. The concern subscale consisted of respondents' evaluation of the degree to which they were concerned about: physical or emotional side-effects of SCT, short or long-term side-effects, death, uncertainty about the procedure, effect of SCT on the patient's ability to do daily activities, financial difficulties, finding an adequate donor, and conflicts with religious or ethical beliefs. Logistic regression was used to examine the direct effect of each of the three predictor variables on the outcome variable, selection or refusal of SCT. Results Respondents for 223 individuals with FA (44% of those surveyed) were included in this analysis. The median age of patients at the time of diagnosis was 4.8 years (0-41 years); the median age at the time of transplant was 9.1 years (1.7-41.2 years). The majority of respondents were mothers (85%); fathers represented 10% of the final sample. A majority of patients included in the present analysis had SCT (83%), and a smaller majority were living at the time the survey was completed (64%). The subscale items exhibited good internal consistency reliability (αa > 0.80). In bivariate analyses, only perceived necessity and risk showed significant relationships with the outcome variable, SCT (p < 0.01). However, in multivariate logistic regression analyses including all three predictor variables, only perceived necessity of SCT was significantly associated with the decision to undergo SCT. Conclusions This is the first study to explore factors related to the utilization of SCT in FA. Our results demonstrated that the majority of subjects opted for SCT and that perceived necessity and risk of SCT were significantly related to the decision, while concern related to the SCT procedure was not. The perceived necessity of SCT was the most important factor for decision-making. These results suggest areas of emphasis for future research and counseling of FA patients and their family members.
