    “Doing What Matters in Times of Stress” to decrease psychological distress during Covid-19: a rammed controlled pilot trial
    (Wolters Kluwer Medknow Publications, 2022) Uygun, Ersin; Karaoğlan Kahiloğulları, Akfer; Department of Psychology; Department of Psychology; N/A; Acartürk, Ceren; Kurt, Gülşah; İlkkurşun, Zeynep; Faculty Member; Teaching Faculty; Master Student; Department of Psychology; College of Social Sciences and Humanities; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 39271; 368619; N/A
    Despite the increasing psychological distress during Covid-19, utilisation of face-to-face psychological interventions decreased profoundly. The aim of this study involving two parallel, two-armed pilot randomised controlled trials was to examine the effectiveness of a guided self-help intervention "Doing What Matters in Times of Stress" (DWM) in decreasing psychological distress in Turkish and Syrian participants. Seventy-four Turkish nationals and 50 Syrian refugee adults with psychological distress were randomly allocated to a DWM group or wait-list control group. The primary outcome measure was the Patient Health Questionnaire 9 postintervention. Secondary outcome measures were the Generalised Anxiety Disorder Scale, posttraumatic stress disorder (PTSD) Checklist for DSM-5, Generalized Self-Efficacy Scale and Acceptance and Action Questionnaire-II postintervention. Although this study was not powered to detect a significant effect for DWM postassessment between DWM and the control group, results showed a significant improvement in depression symptoms among Turkish participants in the DWM group (d = 0.46) and in PTSD symptoms among Syrian participants in the DWM group (d = 0.67) from pre- to postintervention assessment. These results indicate the potential of DWM to decrease mental health problems during the pandemic and importance of a fully powered, definitive controlled trial to examine its effectiveness both for the host community and refugees to reduce psychological distress during Covid-19.

    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 Humanities
    Objective: 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.

    A comprehensive investigation of associations of objective and subjective socioeconomic status with perceived health and subjective well-being
    (Ubiquity Press, 2020) Department of Psychology; N/A; Cemalcılar, Zeynep; Kezer, Murat; Faculty Member; Master Student; Department of Psychology; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 40374; N/A
    Socioeconomic status (SES) accounts for disparities in health and well-being. Recent studies consider the effects of individuals’ subjective standing in society (i.e., subjective SES) as well as the traditional (objective) indicators of SES (i.e., income, education, occupational status), in predominantly Western samples. This study presents a comprehensive investigation of associations of objective and subjective SES with individuals’ perceived health and well-being in a representative sample of young adults (aged 18–35; N = 3016) from a non-WEIRD (Western, Educated, Industrialized, Rich and Democratic) population (i.e., Turkey), employing polynomial regressions and plotting the results onto a three-dimensional plane. Findings confirmed the value of polynomial regression to understanding the relationship of different types of SES with perceived health and well-being. For instance, while perceived overall health was descriptively greater when objective-SES exceeded subjective-SES, the reverse was the case for happiness, one indicator of well-being. Our findings also suggest an additive effect of the two types of socioeconomic status on majority of the outcome variables; individuals’ perceptions of overall health, life satisfaction, happiness, and financial satisfaction were enhanced when they reported higher scores on both objective and subjective SES.

    A cross-cultural analysis of participative decision-making in organizations
    (Sage, 2003) Sagie, Abraham; Department of Psychology; Aycan, Zeynep; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 5798
    Despite considerable awareness about various forms and meanings of participative decision-making (PDM) in different parts of the world, there is less agreement on the causes of variation in PDM. This article argues that among other exogenous (e.g. sociopolitical, legal, historical) forces, the sociocultural context plays an important role in the observed differences among PDM approaches and practices across nations. Similarly, subcultures and organizational cultures may influence PDM within nations. Two cultural dimensions: individualism-collectivism and power distance, are linked with four widespread employee participation approaches: face-to-face PDM, collective PDM, pseudo-PDM, and paternalistic PDM. The attributes of each PDM form, including the cultural determinants, underlying beliefs, the types of decisions made, and the relationship between a specified form and other PDM meanings (e.g. self-managing teams) are elaborated.

    A cross-cultural study of explicit and implicit motivation for long-term volunteering
    (Sage, 2016) Bender, Michael; Chasiotis, Athanasios; van de Vijver, Fons J. R.; Cemalcilar, Zeynep; Chong, Alice; Yue, Xiaodong; Department of Psychology; Cemalcılar, Zeynep; Aydınlı, Arzu; Faculty Member; PhD Student; Department of Psychology; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 40374; N/A
    We propose a model of volunteering and test its validity across four cultural groups. We hypothesize that individuals' explicit prosocial motivation relates positively to sustained volunteering, which is conceptualized as a latent factor comprising activity as a volunteer, service length, service frequency, and hours of volunteering. Moreover, we introduced implicit prosocial motivation and hypothesized that the relationship between explicit prosocial motivation and sustained volunteering would be amplified by implicit prosocial motivation. Data were collected from samples in China, Germany, Turkey, and the United States. Results confirmed our expectation that, across cultures, sustained volunteering was associated with explicit prosocial motivation and that the relationship between explicit prosocial motivation and sustained volunteering was strongest when implicit prosocial motivation was also high. By including implicit prosocial motivation, our study offers a novel approach to identifying sustained volunteer involvement, which can be of particular relevance for recruitment activities of voluntary organizations across various cultural contexts.

    A decision model of timing
    (Elsevier Science Bv, 2016) Simen, Patrick; Department of Psychology; Balcı, Fuat; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 51269
    The fundamental assumption of pacemaker accumulator models of interval timing is that timed behavior relies on the accumulation of brain-derived clock signals. Following this theoretical tradition, a recent series of interval timing models has formulated the processing dynamics of timing behavior within the drift-diffusion decision theoretic framework, which has been traditionally applied to explain accuracy and response times in perceptual decision making. The generative processes assumed by these models and their key features can be implemented by neural populations given simple assumptions, and their predictions have received recent support from electrophysiological studies. This paper discusses the conceptual links of the diffusion model of interval timing to other prominent timing models and interprets recent electrophysiological evidence in relation to its predictions.

    A longitudinal study of the adaptation of international students in the united states
    (Sage, 2008) Falbo, Toni; Department of Psychology; Cemalcılar, Zeynep; Faculty Member; Department of Psychology; College of Social Sciences and Humanities; 40374
    The authors conducted a longitudinal study of international students (N = 90) attending a U. S. university to examine the effects of the initial cross-cultural transition on their psychological well-being and social and academic adaptations. The results indicate a significant decline in self-reports of psychological well-being, increased identification with the host culture, and stable identification with home cultures. Students who exhibit a separation strategy previous to their sojourn have the lowest level of social adaptation to the host culture.

    In a now-classic study by Srull and Wyer (1979), people who were exposed to phrases with hostile content subsequently judged a man as being more hostile. And this “hostile priming effect” has had a significant influence on the field of social cognition over the subsequent decades. However, a recent multi-lab collaborative study (McCarthy et al., 2018) that closely followed the methods described by Srull and Wyer (1979) found a hostile priming effect that was nearly zero, which casts doubt on whether these methods reliably produce an effect. To address some limitations with McCarthy et al. (2018), the current multi-site collaborative study included data collected from 29 labs. Each lab conducted a close replication (total N = 2,123) and a conceptual replication (total N = 2,579) of Srull and Wyer's methods. The hostile priming effect for both the close replication (d = 0.09, 95% CI [-0.04, 0.22], z = 1.34, p =.16) and the conceptual replication (d = 0.05, 95% CI [-0.04, 0.15], z = 1.15, p =.58) were not significantly different from zero and, if the true effects are non-zero, were smaller than what most labs could feasibly and routinely detect. Despite our best efforts to produce favorable conditions for the effect to emerge, we did not detect a hostile priming effect. We suggest that researchers should not invest more resources into trying to detect a hostile priming effect using methods like those described in Srull and Wyer (1979).
