Publication Metadata only Complementing the united states household food security survey module with items reflecting social unacceptability(Elsevier B.V., 2024) Frongillo, Edward A; Bethancourt, Hilary J; Norcini Pala, Andrea; Maya, Sigal; Wu, Katherine C; Kizer, Jorge R; Tien, Phyllis C; Kempf, Mirjam-Colette; Hanna, David B; Appleton, Allison A; Merenstein, Daniel; D'Souza, Gypsyamber; Ofotokun, Igho; Konkle-Parker, Deborah; Michos, Erin D; Krier, Sarah; Stosor, Valentina; Weiser, Sheri D; Department of Psychology; Turan, Bülent; Department of Psychology; College of Social Sciences and HumanitiesBackground: Social unacceptability of food access is part of the lived experience of food insecurity but is not assessed as part of the United States Household Food Security Survey Module (HFSSM). Objectives: The objectives were as follows: 1) to determine the psychometric properties of 2 additional items on social unacceptability in relation to the HFSSM items and 2) to test whether these 2 items provided added predictive accuracy to that of the HFSSM items for mental health outcomes. Methods: Cross-sectional data used were from the Intersection of Material-Need Insecurities and HIV and Cardiovascular Health substudy of the Multicenter AIDS Cohort Study/Women's Interagency HIV Study Combined Cohort Study. Data on the 10-item HFSSM and 2 new items reflecting social unacceptability were collected between Fall 2020 and Fall 2021 from 1342 participants from 10 United States cities. The 2 social unacceptability items were examined psychometrically in relation to the HFSSM-10 items using models from item response theory. Linear and logistic regression was used to examine prediction of mental health measured by the 20-item Center for Epidemiologic Studies Depression scale and the 10-item Perceived Stress Scale. Results: The social unacceptability items were affirmed throughout the range of severity of food insecurity but with increasing frequency at higher severity of food insecurity. From item response theory models, the subconstructs reflected in the HFSSM-10 and the subconstruct of social unacceptability were distinct, not falling into one dimension. Regression models confirmed that social unacceptability was distinct from the subconstructs reflected in the HFSSM-10. The social unacceptability items as a separate scale explained more (∼1%) variation in mental health than when combined with the HFSSM-10 items in a single scale, and the social unacceptability subconstruct explained more (∼1%) variation in mental health not explained by the HFSSM-10. Conclusions: Two social unacceptability items used as a separate scale along with the HFSSM-10 predicted mental health more accurately than did the HFSSM-10 alone.Publication Metadata only Effect of biofeedback-based interventions on the psychological outcomes of pediatric populations: a systematic review and meta-analysis(Springer/Plenum Publishers, 2023) Umaç, Eyşan Hanzade; Semerci, Remziye; Graduate School of Health Sciences; School of NursingWe performed a systematic and meta-analytic review of biofeedback-based interventions on psychological outcomes among pediatric populations. The literature search for this study was conducted in eight databases, including PubMed, the Cochrane Library, Scopus, CINAHL, Embase (OVID), Web of Science, PsycINFO (all via Ovid SP), and Google Scholar. The methodological quality of the studies was assessed using the Critical Appraisal Checklists for experimental and quasi-experimental studies that was developed by the Joanna Briggs Institute. We analyzed the effects of biofeedback-based interventions on psychological outcomes in the pediatric population by following the Preferred Reporting System for Systematic Reviews and Meta-Analysis. This systematic review and meta-analysis included nine studies with a total sample size of 658 children. In this study, EEG, EMG, and heart rate variability biofeedback were utilized to treat psychological symptoms in children. All studies focused on anxiety, with only one studying depression. As a result, it was found that all types of biofeedback effectively reduced children's anxiety levels. It was recommended that biofeedback-based interventions should be used to reduce children's anxiety.Publication Metadata only A Bayesian network analysis to examine the effects of HIV stigma processes on self-concept and depressive symptoms among persons living with HIV(Wiley, 2024) Pala, Andrea Norcini; Department of Psychology; Turan, Bülent; Department of Psychology; College of Social Sciences and HumanitiesObjective: This study examines the relationships between HIV stigma dimensions, self-related mechanisms, and depressive symptoms among persons living with HIV. Background: HIV stigma hinders the well-being of individuals living with HIV, which is linked to depressive symptoms and increased risk of poor clinical outcomes. However, the mechanisms underlying stigma's impact on depression are poorly understood. Psychosocial theories propose that experiencing HIV stigma leads to internalized stigma, impacting self-concept and mental health. Method: Using Bayesian network analysis, we explored associations among HIV stigma processes (experienced, anticipated, internalized, perceived community stigma, and HIV status disclosure) and self-related mechanisms (self-esteem, fear of negative evaluation [FNE], self-blame coping, and social exclusion), and depressive symptoms. Results: Our diverse sample of 204 individuals, primarily men, gay/bisexual, Black, and lower-middle SES, who experienced stigma showed increased anticipated, internalized, and perceived community stigma, FNE, and depressive symptoms. Internalized stigma contributed to self-blame coping and higher depressive symptoms. Anticipated and perceived community stigma and FNE correlated with increased social exclusion. Discussion: This study investigates potential mechanisms through which HIV stigma may impact depression. Identifying these mechanisms establishes a foundation for future research to inform targeted interventions, enhancing mental health and HIV outcomes among individuals living with HIV, especially from minority backgrounds. Insights gained guide evidence-based interventions to mitigate HIV stigma's detrimental effects, ultimately improving overall well-being and health-related outcomes for people with HIV.Publication Metadata only Acceptability, feasibility and potential of an intervention using secret Facebook groups to complement existing HIV prevention strategies among female sex workers in Cameroon, a randomized pilot study(Routledge Journals, Taylor & Francis Ltd, 2023) Vazquez Guillamet, Laia J.; Babey, Mary Mah; Njah, Mercy; Blake, Hassanatu; Jasani, Amy; Kyeng, Rahel; Hao, Jiaying; Long, Dustin; Tih, Pius; Turan, Janet M.; Khan, Eveline Mboh; Dionne, Jodie; Turan, Janet Molzan; School of MedicineThis randomized pilot project evaluated an intervention promoting health care literacy around HIV, pre-exposure prophylaxis (PrEP), and stigma reduction using private social media groups that complemented existing HIV prevention services among female sex workers (FSWs) in Cameroon. The intervention was 12 HIV and sexual health videos tailored to FSWs that were released over 8 weeks through a secret Facebook group platform. In-person surveys were administered before, after the intervention, and three months later. No HIV seroconversions were detected; all participants completed follow-up and agreed to recommend the intervention to a coworker. Although the intervention was assessed to be acceptable and feasible to implement, poor internet connectivity was a key barrier. In time-series analysis, the intervention group participants reported improved PrEP interest, PrEP knowledge, and condom use along with reduced PrEP and HIV-related stigma, but no impact on sex-work related stigma or social cohesion. Similar results occurred in the control group. Cross-contamination and small pilot study size might have hindered the ability to detect the differential impact of this intervention. As communications technology increases in Cameroon, it is essential to learn more about FSWs preferences on the use of social media platforms for HIV prevention strategies.Publication Metadata only Face and emotion recognition in individuals diagnosed with schizophrenia, ultra-high risk for psychosis, unaffected siblings, and healthy controls in a sample from Turkey(Elsevier, 2024) Sağdıç, Meylin; Erciş, Mete; Üçok, Alp; İzgi, Büşra; Eser, Hale Yapıcı; Kuşçu, Kemal; Graduate School of Health Sciences; School of MedicineFace and emotion recognition are crucial components of social cognition. We aimed to compare them in patients diagnosed with schizophrenia (SCZ), ultra-high risk for psychosis (UHR), unaffected siblings of schizophrenia patients (SIB), and healthy controls (HC). Methods: One hundred sixty-six participants (45 SCZ, 14 UHR, 45 SIB, and 62 HC) were interviewed with the Structured Clinical Interview for DSM-5 (SCID-5). Positive and Negative syndrome scale (PANSS), PennCNB Facial Memory (CPF), and Emotion Recognition Task (ER40) were applied. Results: In CPF, SCZ performed significantly lower than SIB and HC. SIB was also significantly lower than HC for total correct responses. The sample size of the UHR group was small, and the statistical comparisons did not reach a significance, however, a trend towards decreased performance between the SCZ and SIB was found. In ER40, SCZ performed significantly lower than HC and SIB in all domains, except for the insignificant findings for angry ER between SIB and SCZ. SIB also performed significantly lower than HC for angry, negative, and total ER. UHR was similar to SCZ for happy and sad ER and performed significantly lower than HC for happy ER. The effect of SCZ diagnosis on the efficiency of CPF and ER40 was significant when corrected for age and education. For SCZ, PANSS also significantly affected the CPF and ER40. Conclusion: Our findings suggest varying levels of face and emotion recognition deficits in individuals with SCZ, UHR, and SIB. Face and emotion recognition deficits are promising schizophrenia endophenotypes related to social cognition.Publication Metadata only Nursing students’ views about do-not-resuscitate orders: quasi-experimental study(Sage Publications Inc., 2024) Tas Arslan, Fatma; Ozkan, Sevil; Bağçivan, Gülcan; ; School of Nursing;“Do Not Resuscitate” (DNR) order is one of the challenging issues encountered in end of life care. This study aimed to determine the effect of education about DNR on the views of senior nursing students. Students, who selected elective course of palliative care and received education about DNR formed the intervention group (n = 106) while the students who did not select the lesson were in the control group (n = 107). Data were collected using a questionnaire. It revealed that the students who had education about DNR agreed with the positive statements about DNR more than the control group. Also, intervention group students had a high agreement DNR should be a part of vocational training for health professionals. It is important and necessary to focus on the special role of nurses when a DNR order is given, and nursing education raised the awareness and views about DNR according to the data from this study. © The Author(s) 2022.Publication Metadata only Understanding patterns of accumulation: improving forecast-based decisions via nudging(Springer, 2024) Boz-Yilmaz, Hatice Zulal; Department of Psychology; Gököz, Zeynep Ayşecan Boduroğlu; Department of Psychology; College of Social Sciences and HumanitiesIn this study we investigated challenges associated with comprehension of graphical patterns of accumulation (Experiment 1) and how to improve accumulation-based reasoning via nudging (Experiment 2). On each trial participants were presented with two separate graphs, each depicting a linear, saturating, or exponential data trajectory. They were then asked to make a binary decision based on their forecasts of how these trends would evolve. Correct responses were associated with a focus on the rate of increase in graphs; incorrect responses were driven by prior knowledge and beliefs regarding the context and/or selective attention towards the early phases of the line trajectories. To encourage participants to think more critically and accurately about the presented data, in Experiment 2, participants completed a nudge phase: they either made a forecast about a near horizon or read particular values on the studied trajectories prior to making their decisions. Forecasting about how the studied trajectories would progress led to improvements in determining expected accumulation growth. Merely reading values on the existing trajectory did not lead to improvements in decision accuracy. We demonstrate that actively asking participants to make specific forecasts prior to making decisions based on the accumulation trajectories improves decision accuracy.Publication Metadata only The role of culture and semantic organization in working memory updating(Routledge Journals, Taylor and Francis Ltd, 2024) Leger, Krystal R.; Snyder, Hannah R.; Gutchess, Angela; Department of Psychology; Gököz, Zeynep Ayşecan Boduroğlu; Department of Psychology; College of Social Sciences and HumanitiesWesterners tend to relate items in a categorical manner, whereas Easterners focus more on functional relationships. The present study extended research on semantic organization in long-term memory to working memory. First, Americans' and Turks' preferences for categorical versus functional relationships were tested. Second, working memory interference was assessed using a 2-back working memory paradigm in which lure items were categorically and functionally related to targets. Next, a mediation model tested direct effects of culture and semantic organization on working memory task behaviour, and the indirect effect, whether semantic organization mediated the relationship between culture and working memory interference. Whereas Americans had slower response times to correctly rejecting functional lures compared to categorical lures, conditions did not differ for Turks. However, semantic organization did not mediate cultural difference in working memory interference. Across cultures, there was evidence that semantic organization affected working memory errors, with individuals who endorsed categorical more than functional pairings committing more categorical than functional errors on the 2-back task. Results align with prior research suggesting individual differences in use of different types of semantic relationships, and further that literature by indicating effects on interference in working memory. However, these individual differences may not be culture-dependent.Publication Metadata only The flashbulb-like nature of memory for the first Covid-19 case and the impact of the emergency. A cross-national survey(Routledge Journals, Taylor and Francis Ltd, 2024) Lanciano, Tiziana; Alfeo, Federica; Curci, Antonietta; Marin, Claudia; D'Uggento, Angela Maria; Decarolis, Diletta; Oner, Sezin; Anthony, Kristine; Barzykowski, Krystian; Bascon, Miguel; Benavides, Alec; Cabildo, Anne; de la Mata-Benitez, Manuel Luis; Filip, Katarzyna; Gofman, Alena; Janssen, Steve M. J.; Kai-bin, Zhao; Markostamou, Ioanna; Matias-Garcia, Jose Antonio; Nourkova, Veronika; Oleksiak, Sebastian; Santamaria, Andres; Szpunar, Karl; Taylor, Andrea; Watson, Lynn Ann; Zheng, Jin; Department of Psychology; Ergen, İrem; Department of Psychology; College of Social Sciences and HumanitiesFlashbulb memories (FBMs) refer to vivid and long-lasting autobiographical memories for the circumstances in which people learned of a shocking and consequential public event. A cross-national study across eleven countries aimed to investigate FBM formation following the first Covid-19 case news in each country and test the effect of pandemic-related variables on FBM. Participants had detailed memories of the date and others present when they heard the news, and had partially detailed memories of the place, activity, and news source. China had the highest FBM specificity. All countries considered the Covid-19 emergency as highly significant at both the individual and global level. The Classification and Regression Tree Analysis revealed that FBM specificity might be influenced by participants' age, subjective severity (assessment of Covid-19 impact in each country and relative to others), residing in an area with stringent Covid-19 protection measures, and expecting the pandemic effects. Hierarchical regression models demonstrated that age and subjective severity negatively predicted FBM specificity, whereas sex, pandemic impact expectedness, and rehearsal showed positive associations in the total sample. Subjective severity negatively affected FBM specificity in Turkey, whereas pandemic impact expectedness positively influenced FBM specificity in China and negatively in Denmark.Publication Metadata only Autobiographical phenomenology of memories of fiction(Routledge Journals, Taylor and Francis Ltd, 2024) Department of Psychology; Çetin, Osman Görkem; Gülgöz, Sami; Department of Psychology; Graduate School of Social Sciences and Humanities; College of Social Sciences and HumanitiesMost autobiographical memories are based on real-life experiences, but memories of fiction have many similarities to real-life autobiographical memories. However, the phenomenological nature of this similarity, the potential differences between media types, and the role of individual differences need further investigation. Based on previous findings, we expected differences between media types on emotional intensity, sensory vividness, and confidence about the recall. To provide insight into these issues, we collected one real-life autobiographical memory and one memory of fiction (book, film, or video game) from 291 participants. We asked them to rate their memories phenomenologically. The participants also provided information regarding their motivations for engaging with fictional stories. Our results show phenomenological differences in several dimensions between media types and differences in the similarity of media types to real-life memories. While absorption seems to be a good predictor for immersion, escapism tendency is a motivation to engage with fiction frequently.
