In minority educational contexts, however, students' psychological need satisfaction is also shaped by broader sociocultural conditions that may create additional pressures and sources of chronic stress. Within such environments, parental support may function as a protective factor that helps students cope with educational and cultural demands. Objective: The aim of this study was to explore how parental support contributes to the satisfaction of students' basic psychological needs within a minority educational context where students from the Greek minority attend a bilingual school operating within a Turkish educational framework. Methods: A qualitative design was employed using three focus groups conducted in a minority school located in Gökçeada, Türkiye: one with parents (N = 5), one with lower secondary school students (N = 6), and one with upper secondary school students (N = 6). Interview questions were developed on the basis of Basic Psychological Needs Theory. Data were analyzed thematically by five members of the research team. Results: Findings indicated that parental support influenced students' need satisfaction through practices related to autonomy (e.g., trust, space for mistakes), competence (e.g., encouragement, comparison), and relatedness (e.g., emotional presence, empathy). However, these practices were not experienced in a uniform way. Rather, their meaning and impact were shaped by contextual conditions associated with minority status, including bilingual educational demands, limited resources, and close-knit community dynamics. Conclusions: The study suggests that in minority school settings, parental support operates not simply as a general interpersonal resource but as a contextually mediated protective process. By showing how sociocultural and institutional conditions shape the enactment and experience of autonomy, competence, and relatedness, the findings extend existing BPNT research beyond majority settings and offer a more context-sensitive understanding of students' psychological need satisfaction.Article Psychological Intimate Partner Violence Across Identities: Preliminary Psychometrics of the Multidimensional Measure of Emotional Abuse-Short Form Among Heterosexual, Lesbian, and Bisexual Samples in Türkiye(ARCHIVES OF SEXUAL BEHAVIOR, 2026) Toplu Demirtaş, Ezgi; Zurnaci, Burcu; Demirtaş, Ezgi Toplu; 06.01. Department of Guidance and Psychological Counseling; 06. Faculty of Education; 01. MEF UniversityPsychological intimate partner violence (IPV) affects individuals across diverse sexual identities and is often reinforced by romantic myths. Despite its substantial mental health consequences, psychological IPV remains under-recognized and insufficiently researched. One barrier is the scarcity of brief, inclusive, and psychometrically sound tools for assessing psychological IPV across varied populations. To address this gap, the present study aimed to validate the short form of the Turkish version of the Multidimensional Measure of Emotional Abuse (MMEA-TR). This 16-item scale evaluates four subdimensions of psychological IPV (Restrictive Engulfment, Denigration, Hostile Withdrawal, and Dominance/Intimidation) while preserving the original multidimensional framework. Data were collected from four independent samples in T & uuml;rkiye: Bisexual individuals (n = 230, M = 22.88, SD = 4.49), predominantly heterosexual women (n = 237, M = 24.30, SD = 2.51), lesbian and bisexual women (n = 178, M = 29.06, SD = 7.81), and predominantly heterosexual men (n = 160, M = 24.49, SD = 2.54). Confirmatory factor analyses across samples supported the hypothesized four-factor model and demonstrated acceptable fit indices. Subscales showed significant intercorrelations and concurrent validity was supported by theoretically consistent associations with jealousy (Study 1), anxious attachment (Study 2), internalized heterosexism (Study 3), and fragile masculinity (Study 4). Internal consistency reliability ranged from acceptable to high across groups. Overall, findings provide initial evidence for the construct validity, concurrent validity, and reliability of the MMEA-TR short form. This study contributes a brief, inclusive, and psychometrically robust instrument for assessing psychological IPV in both heterosexual and sexual minority populations.Article The Cost of Curiosity: Information-Reward Tradeoffs in Early Childhood(Elsevier Science Inc, 2026) Lucca, Kelsey; Sen, Hilal H.; 01. MEF UniversityCuriosity is a powerful engine of learning that shapes how people explore, acquire knowledge, and adapt to their environments. Though the implications of curiosity are clear, we know little about what drives curiosity. One widely-held view is that satisfying curiosity is intrinsically rewarding. Yet there is limited direct evidence supporting this claim, particularly during early childhood-a period characterized by heightened curiosity. Here, we provide an empirical test of whether satisfying curiosity is intrinsically valuable to children by asking whether they will forego hard-earned rewards to obtain information. To examine the limits of costly curiosity, we ask whether children will give up hard-earned rewards to learn something new, even when the information to be gained is unknown and offers no immediate or long-term benefit. Critically, we test what factors (i.e., age, gender, cultural background, trait curiosity, reward availability) shape children's willingness to engage in costly curiosity. In a sample of 226 children aged 3-6 years in the United States and Turkey, nearly all children (87%) gave up rewards to obtain information. However, costly curiosity was limited, most children gave up only a few rewards (i.e., the smallest amount possible), and the extent of trading varied by gender and culture: boys traded more than girls and children in the United States traded more than in Turkey. These findings provide evidence that children's curiosity is not driven by sheer impulse, but instead, a decision-making process that weighs both costs and benefits, and is shaped by broader individual and cultural factors.Article Longitudinal Norms of Frailty Measured by the Frailty Index: A Cross-National Comparison Using Data from the Survey of Health, Aging, and Retirement in Europe (SHARE)(Elsevier, 2026) Sevi, Barış; Supiyev, Adil; Muniz-Terrera, Graciela; Sevi, Baris; Massa, Fernando; Marroig, Alejandra; 04.02. Department of Psychology; 04. Faculty of Economics, Administrative and Social Sciences; 01. MEF UniversityBackground: Frailty, a geriatric syndrome commonly used to identify vulnerable older adults, is a public health priority. However, the lack of cross-national comparisons of frailty trajectories and their distribution constrains current understanding of normative changes in frailty for residents across different countries. Objective: To derive longitudinal percentiles of frailty using a consistent cross-country approach. Design: Observational study using longitudinal data from the Survey of Health, Ageing and Retirement in Europe (SHARE) between 2004 and 2020. Setting: We fit the distribution of the FI by Generalized Additive Models for Location, Scale, and Shape (GAMLSS), assessed the role of sex (male/female), education (in years), and migration status (migrant/non-migrant), and estimated the longitudinal percentiles of frailty using a consistent cross-country approach for 16 countries. Participants: Individuals aged >= 65 years (N = 42,951) at study entry. Measurements: Frailty index (FI) based on the accumulation of deficits in 40 items. Results: The results show that education is protective against frailty in all countries (a decrease of 1.1 pp. in Switzerland to 5.7 pp. in Slovenia, all p < 0.001). In most countries, women are frailer than men and migrant individuals have higher levels of frailty than non-migrants. FI trajectories showed heterogeneity across countries. The quantiles for women and migrants suggest frailer trajectories than men and non-migrants respectively. Conclusions: Findings from this cross-national comparison provide a framework within which the longitudinal norms of frailty trajectories from different countries can be interpreted.Article Robust HMM-Based Remaining Useful Life Estimation Using a Ridge-Regularized EM Algorithm(MDPI, 2026) Kucukdag, Halime Beyza; Kirkil, Gokhan; Hekimoglu, Mustafa; 01. MEF UniversityEstimating the remaining useful life (RUL) of engineering systems is crucial for maintenance planning and the reliability of complex mechanical units. Accurate RUL predictions support timely interventions and help to prevent unexpected failures. This study proposes a statistically robust framework that models degradation signals up to the end of life using a hidden Markov model (HMM) with a simple-failure structure and an absorbing terminal state. The proposed method estimates state-dependent linear emission parameters and transition probabilities using a ridge-regularized expectation-maximization (EM) algorithm. The ridge penalty stabilizes slope estimates under limited data, while a robust Huber-based scale estimator reduces sensitivity to outliers in the sensor-derived health indicator. RUL is computed as a weighted expected time to absorption, combining transient-state survival characteristics with smoothed posterior-state probabilities obtained via the forward-backward algorithm. This yields a low-variance state-aware estimator that preserves the probabilistic structure of the HMM. Simulation studies show that the proposed ridge-regularized EM significantly reduces parameter variance and improves predictive accuracy compared with the baseline weighted least squares EM (WLS-EM). A real-data case analysis demonstrates further improvements in RUL estimation accuracy and smoother, more reliable prediction trajectories. Overall, the framework provides a robust and interpretable approach for practical prognostics applications.Article Mice Extrapolate Temporal Information Based on Previously Learned Spatiotemporal Mappings: An Asymmetrical Case(Springer, 2026) Gur, Ezgi; Duyan, Yalcin A.; Toptas, Pinar; Balci, Fuat; 01. MEF UniversityOne of the computational affordances of isomorphic magnitude representations is the extrapolation of temporal information based on previously experienced spatiotemporal pairings. We initially trained mice on the association of two intervals (10 s and 30 s) with two hoppers (H2 and H4, counterbalanced) in a five-choice nose-poke box with the following setup. One of the three novel hoppers (H1) neighbored H2 only, the other novel hopper (H5) neighbored H4 only, and the third novel hopper (H3) neighbored H2 and H4 (H1Novel -> H2Trained -> H3Novel -> H4Trained -> H5Novel). During test trials, one of the five hoppers was illuminated. We estimated the trial time at which the anticipatory response rate was maximal (peak time) separately for each hopper. Mice extrapolated temporal information only in a forward fashion; the peak time for H5 was longer than that for H4. Mice did not extrapolate temporal information backward; the timed response curves in H1 and H3 were closely similar to those in H2. Thus, our findings suggest that mice can extrapolate temporal information, but also indicate that the computations underlying this process are directionally constrained. We discuss the possible reasons behind asymmetrical extrapolation.Article Citation - WoS: 2Citation - Scopus: 2Gender Differences in Cyber Dating Violence Among Adolescents and Young Adults: A Systematic Review and Meta-Analysis(Wiley, 2025) Toplu Demirtaş, Ezgi; Metin, Ahmet; Zencir, Tolga; Boranli, Ece Nur; Demirtas, Ezgi Toplu; Sen, Sedat; 01. MEF University; 06.01. Department of Guidance and Psychological Counseling; 06. Faculty of EducationDespite the growing body of research on cyber dating violence, a comprehensive understanding of gender differences in cyber-violent behaviors across developmental stages remains limited. The main purpose of this meta-analytic review was to estimate the direction and magnitude of gender differences in cyber dating violence perpetration and victimization by synthesizing results from various studies. The second purpose of this study was to examine the effect of potential moderators (i.e., continent, age, grade level, time frame, method of survey administration, the metric of the outcome, study design, publication status, and publication year) on these differences. Various databases were used to identify relevant studies, including PubMed, Web of Science (WoS), Scopus, PsycINFO, ERIC, and ProQuest. Eighty-one individual studies with a total sample of 70,233 participants, ranging in age from 10 to 30 years (M = 18.94), were included based on the inclusion and exclusion criteria in the present study. Most studies were conducted in North America and Europe with the largest proportions from the United States and Spain. Results indicated that there were no statistically significant gender differences (women vs. men; girls vs. boys) in perpetration and victimization of cyber dating violence. Moderator analyses showed that grade level and sample age were statistically significant moderators of gender differences in cyber dating violence victimization. However, other moderators (continent, time frame, method of survey administration, the metric of the outcome, study design, publication status, and publication year) were not statistically significant. This study contributes to understanding gender differences in cyber-violent behaviors during adolescence and emerging adulthood and highlights the importance of some moderators when developing targeted prevention and intervention strategies.Article Big-5 Personality Traits as Predictors of Allostatic Load in Latino Americans: A Longitudinal Study(Oxford Univ Press Inc, 2025) Sevi, Barış; Supiyev, Adil; Gutierrez, Angela; Graham, Eileen K.; Mroczek, Daniel K.; Muniz-Terrera, Graciela; 01. MEF University; 04. Faculty of Economics, Administrative and Social Sciences; 04.02. Department of PsychologyObjectives Allostatic load (AL) refers to the measure of cumulative wear and tear resulting from chronic stress and life events. AL presents adverse consequences for a diverse range of health conditions, and Latino populations show a high risk for elevated AL. This study aimed to test the Big-5 personality traits as possible predictors of AL in Latinos.Methods Using data from the Health and Retirement Study, we examined the Big-5 and AL connection through three time points in 8 years (Time 1 = 2006/2008; Time 2 = 2010/2012; Time 3 = 2014/2016). Only self-identified Latinos were included in the analysis sample (N = 319). Big-5 and demographics were obtained at baseline, and AL scores were computed for each time point.Results First, separate longitudinal linear mixed-effect models examined the effects of each Big-5 personality trait on AL change over time, then a fully adjusted longitudinal linear mixed-effect model was tested entering the Big-5 personality traits simultaneously. All models controlled for sociodemographic factors. Conscientiousness emerged as the only consistent significant predictor, for the separate and the simultaneous models. In baseline associations, higher conscientiousness was associated with lower AL. For predicting change in AL over time, none of the personality traits had significant associations in any of the models.Discussion The findings bolster prior evidence that conscientious can be a protective factor against elevated AL. Conscientiousness is a possible protective factor and improving related traits can be a path to achieve better health in Latino Americans.Article Citation - WoS: 2Citation - Scopus: 2The Shadows of Internalized Bisexual Myths: Jealousy and Psychological Intimate Partner Violence Perpetration Among Bisexual Plus Individuals in Turkiye(SAGE Publications Inc, 2025) Toplu Demirtaş, Ezgi; Demirtas, Ezgi Toplu; Toplu Demirtaş, Ezgi; 01. MEF University; 06.01. Department of Guidance and Psychological Counseling; 06. Faculty of EducationBisexual+ (bi+) individuals may face unique challenges stemming from the internalization of myths related to their sexual orientation. This internalization may make individuals more sensitive to perceived threats in their relationships, which can increase feelings of jealousy. In turn, internalized bisexual myths and heightened jealousy may contribute to the perpetration of psychological intimate partner violence (IPV) within bi+ relationships. Thus, in this study, we aimed to examine the parallel mediating roles of cognitive and emotional jealousy in the association between internalized bisexual myths and psychological IPV perpetration. A sample of 230 bi+ individuals from Türkiye completed the (Internalized) Bisexual Myths Scale, the Multidimensional Jealousy Scale, and the Multidimensional Measure of Emotional Abuse Short Form. Overall, 94.3% of bi+ individuals reported perpetrating at least one act of psychological IPV against their partners within the past 6 months. Results from the parallel mediation analyses revealed that both cognitive and emotional jealousy mediated the relationship between internalized bisexual myths and psychological IPV perpetration. These findings suggest that bi+ individuals who internalize bisexual myths and exhibit higher levels of emotional and cognitive jealousy may be more susceptible to perpetrating psychological IPV against their partners. This study underscores the need for further research to better understand psychological IPV perpetration among bi+ individuals, highlighting the value of qualitative and longitudinal methods for gaining deeper insights.Article Citation - WoS: 1Longitudinal Relations Between Early Prosocial Behaviors Toward Parents and Later Prosocial and Aggressive Behaviors in Turkish Early Adolescents(Amer Psychological Assoc, 2025) Gulseven, Zehra; Selçuk, Ayşe Bilge; Carlo, Gustavo; Maiya, Sahitya; Sayil, Melike; Selcuk, Bilge; 01. MEF University; 04. Faculty of Economics, Administrative and Social Sciences; 04.02. Department of PsychologyBecause Turkish early adolescents learn and practice many essential prosocial behaviors (i.e., helping, sharing) within the family context, it is important to examine whether early adolescents' prosocial behaviors toward parents at age 10 (Time 1) were related to their later prosocial and aggressive behaviors at age 13 (Time 3) via perceived parental psychological control at age 12 (Time 2). Participants were 355 early adolescents (M-age = 9.89 years, SD = 0.32; 51% girls) from Türkiye at Time 1. Early adolescents reported their prosocial behaviors toward mothers and fathers at age 10, perceived maternal and paternal psychological control at age 12, and prosocial and aggressive behaviors at age 13. Mediation analyses showed that early adolescents' greater prosocial behaviors toward parents were significantly related to less perceived psychological control, which, in turn, was related to less altruistic and reactive prosocial behaviors but related to greater reactive and proactive aggressive behaviors. Importantly, these associations were robust across boys and girls, and all indirect effects were statistically significant. The findings inform theories that suggest interindividual stability in youth's levels of prosocial behavior and reciprocal relations between parenting and youth behaviors but extend such findings to a non-Western, relatively collectivist-oriented, predominantly Muslim culture.
