    Turkish sign language adaptation of the Turkish Health Literacy Scale-32
    (NLM (Medline), 2022-09-15) Ataseven Bulun, Mehtap; Çepni, Selden; Ermez, Yusuf
    Sign language speakers are at a disadvantage in terms of health literacy due to the lack of health education materials in sign languages. Deaf and hard of hearing (DHH) individuals are excluded from health literacy research due to the lack of measurement tools in their language of excellent f luency. This study aims to provide the literature with a tool that allows the measurement of health literacy among DHH individuals. The Turkish Health Literacy Scale (THLS)-32 was translated into Turkish Sign Language (TSL). After the THLS-32 was translated into TSL in video format, it was tested for validity and reliability. The translated version of the scale was administered to participants from a DHH association in Turkey who are f luent in TSL. Subsequently, a study was conducted with 207 DHH individuals. The study group was assessed in terms of their mean index scores and evaluated to have “limited health literacy” according to the THLS-32 classification. We conclude that the THLS-32 in TSL is suitable to measure health literacy in DHH individuals and to assess the impact of the health education system.

    A stochastic risk-averse framework for blood donation appointment scheduling under uncertain donor arrivals
    (Springer, 2020-12) Yalçındağ, Semih; Baş Güre, Seda; Carello, Giuliana; Lanzarone, Ettore
    Blood is a key resource in all health care systems, usually drawn from voluntary donors. We focus on the operations management in blood collection centers, which is a key step to guarantee an adequate blood supply and a good quality of service to donors, by addressing the so-called Blood Donation Appointment Scheduling problem. Its goal is to employ appointment scheduling to balance the production of blood units between days, in order to provide a reasonably constant supply to transfusion centers and hospitals, and reduce non-alignments between physicians' working times and donor arrivals at the collection center. We consider a two-phase solution framework taken from the literature, in which a deterministic linear programming model preallocates time slots to different blood types and a prioritization policy assigns the preallocated slots to the donors when they make a reservation. However, the problem is stochastic in nature and requires consideration of the uncertain arrivals of non-booked donors. In this work, to include the uncertain arrivals, we propose three stochastic counterparts of the preallocation model based on a risk-neutral objective and two risk-averse objectives, respectively, where the Conditional Value-at-Risk is considered as the risk measure in the last two methods. The resulting stochastic frameworks have been tested considering the historical data of one of the largest Italian collection centers, the Milan Department of the "Associazione Volontari Italiani Sangue" (AVIS). Results show the effectiveness of the stochastic models, especially the mean-risk one, and the need to include the uncertainty of arrivals in order to better balance the production of blood units.

    Imagined contact facilitates acculturation, sometimes: contradicting evidence from two sociocultural contexts
    (Educational Publishing Foundation-American Psychological Assoc, 2019-10) Bağcı Hemşinlioğlu, Sabahat Çiğdem; Piyale, Zeynep Ecem; Stathi, Sofia
    Objective: Imagined intergroup contact has been shown to be an effective tool to improve intergroup relationships in various settings, yet the application of the strategy among minority group members and across cultures has been scarce. The current research aimed to test imagined contact effects on minority group members' acculturation strategies (contact participation and culture maintenance), perceived discrimination, feelings of belongingness, and social acceptance across three studies conducted in the United Kingdom (Study 1) and Turkey (Studies 2 and 3). Method: The sample consisted of Eastern Europeans in Study 1 (N = 63) and Kurds in Study 2 and 3 (N = 66 and 210, respectively). Participants were randomly assigned to 1 of 2 conditions (control vs. imagined contact) and completed measures of acculturation, perceived discrimination, general belongingness, and social acceptance. Results: Findings showed that while imagined contact significantly reduced perceived discrimination and culture maintenance, and increased contact participation and social acceptance among Eastern Europeans (Study 1), it reduced social acceptance and contact participation among Kurds recruited from a conflict-ridden homogeneous setting (Study 2). With a larger and more heterogeneous sample of Kurds (Study 3), these effects occurred only among those with higher ingroup identification. Moreover, in all studies social acceptance mediated the effects of imagined contact on contact participation and perceived discrimination. Discussion. Findings offer important insights about the use of the imagined contact strategy among minority group members and imply the need to take into account the context-dependent nature of contact strategies.

    Reciprocal relations between the trajectories of mothers’ harsh discipline, responsiveness and aggression in early childhood
    (Springer New York LLC, 2018-01-01) Akçinar Yayla, Berna; Baydar, Nazlı
    Theoretical advances in the study of the development of aggressive behaviors indicate that parenting behaviors and child aggression mutually influence one another. This study contributes to the body of empirical research in this area by examining the development of child aggression, maternal responsiveness, and maternal harsh discipline, using 5-year longitudinal data from a nationally representative sample of Turkish children (n = 1009; 469 girls and 582 boys). Results indicated that: (i) maternal responsiveness and harsh discipline at age 3 were associated with the subsequent linear trajectory of aggression; (ii) reciprocally, aggressive behaviors at age 3 were associated with the subsequent linear trajectories of these two types of parenting behaviors; (iii) deviations from the linear trajectories of the child and mother behaviors tended to be short lived; and, (iv) the deviations of child behaviors from the linear trajectories were associated with the subsequent changes in mother behaviors after age 5. These findings are discussed in the cultural context of this study.

    Pedestrian crossing behavior at midblock crosswalks
    (Elsevier Ltd, 2019-12) Tezcan, Hüseyin Onur; Elmorssy, Mahmoud; Aksoy, Göker
    Introduction: This study investigated the pedestrian crossing behavior at midblock crosswalks, in Istanbul. Method: Data were compiled from field studies at four selected crosswalks that were on one-way streets. Three of the crosswalks were located on three-lane streets while the other one was on a two-lane street. By using two-hour video recordings at each crosswalk, information was collected about pedestrian crossing preferences, pedestrian platoons both at curbside and during the crossing, traffic characteristics including volume, crosswalk occupancy and illegal parking, and pedestrian characteristics comprising age, gender and distraction status. These data were stratified with respect to the number of lanes and two multinomial logit models for platooning and individual crossing behavior was estimated for each stratum. Results: The results showed that the likelihood of platooning increases as the traffic volume and platoon size increase. Moreover, pedestrians who waited for little or no at the curbside and started to cross when one or more lanes were occupied generally lost time during the crossing. In terms of policy, the formation of platoons should be prevented by enforcement or demand-responsive traffic signals with push-to-walk buttons, etc. Overall, the study revealed that the presence of midblock crosswalks is questionable.

    Attentional bias and training in social anxiety disorder
    (Turkish Neuropsychiatric Society, 2015-03) Fıstıkçı, Nurhan; Saatçioğlu, İbrahim Ömer; Keyvan, Ali; Topçuoǧlu, Volkan
    Cognitive behavioral therapy (CBT) is one of the most effective treatment modalities for social anxiety disorder (SAD), showing a high level of clinical evidence supporting its effectiveness. On the other hand, lack of the desired benefit from this treatment in some patients causes continuation of the search for new techniques. Recent research studies have focused on attentional bias and attention training in SAD. Attention processes in SAD have been a major target of interest and investigation since the introduction of the first cognitive models explaining SAD. In the first model, it was highlighted that attention was self-focused. The relationship between threatening stimuli and attention was considered in the subsequent models. Attentional bias towards threat may take place in several ways, such as facilitated processing of threat, difficulty in disengaging attention from the threat and avoidance of attention from the threat. After these descriptions regarding the phenomenology of the disorder, treatments to modify attention, processes were developed. In spite of conflicting results, investigations on attentional training are promising. Attention processes, attentional bias and attentional training in SAD are discussed in this review.

    Anti-tobacco control industry strategies in Turkey
    (BioMed Central Ltd, 2018-02-26) Keklik, Seda; Gültekin Karakas, Derya
    Background: Transnational tobacco companies (TTCs) penetrated the Turkish cigarette market due to trade and investment liberalization in the post-1980 period and eventually secured full control. Despite tobacco control policies put in place in reaction to accelerating consumption, TTCs reinforced their market power through a variety of strategies. This paper explores industry strategies that counteract tobacco control policies in Turkey. Methods: The study employs both qualitative and quantitative analyses to explore industry strategies in Turkey. Besides the content analyses of industry and market reports, descriptive analyses were conducted for the sub-periods of 1999-2015. The analyses focus on the market strategies of product innovation, advertisement-promotion, cost management and pricing. Results: Rising sales of low tar, ultra-low tar, slim, super-slim and flavoured cigarettes indicate that product innovation served to sustain consumption. Besides, the tobacco industry, using its strong distribution channels, the Internet, and CSR projects, were found to have promoted smoking indirectly. The industry also rationalized manufacturing facilities and reduced the cost of tobacco, making Turkey a cigarette-manufacturing base. Tobacco manufacturers, moreover, offered cigarettes in different price segments and adjusted net prices both up and down according to price categories and market conditions. In response to the successful effect of shifts in price margins, the market share of mid-priced cigarettes expanded while those within the economy category maintained the highest market share. As a result of pricing strategies, net sales revenues increased. Aside from official cigarette sales, the upward trends in the registered and unregistered sales of cigarette substitutes indicate that the demand-side tobacco control efforts remain inadequate. Conclusions: The Turkish case reveals that the resilience of the tobacco industry vis-a-vis mainstream tobacco control efforts necessitates a new policy perspective. Rising market concentration by TTCs and the global nature of industry strategies require that the highly profitable manufacturing and trade of tobacco products should be discouraged on a basis of international collaboration. To reduce and eventually eradicate tobacco consumption, supply-side tobacco control measures are needed along with demand-side policies.

    Olanzapin kullanımına bağlı çekilme diskinezisi ve süpersensitivite psikozu
    (Turkish Neuropsychiatric Society, 2016-06) Karaş, Hakan; Güdük, Mehmet; Saatçioğlu, İbrahim Ömer
    Tardive dyskinesia (TD) usually appears after years of antipsychotic drug use and appears to be related to the total lifetime medication dose. In withdrawal-emergent dyskinesia (WE-D), which is considered to be a subtype of TD, dyskinetic symptoms often appear shortly after a rapid reduction in antipsychotic drug dose or sudden discontinuation of the drug. Supersensitivity psychosis, which is frequently observed along with TD and is considered to have a similar etiology as TD, is a psychotic relapse phenomenon that occurs after the withdrawal of an antipsychotic drug or a rapid reduction in the drug dosage. In general, atypical antipsychotics tend to be associated with less propensity to cause TD when compared with typical antipsychotics. Furthermore, olanzapine and clozapine may have a therapeutic potential in improving or totally curing TD. In this study, a case of WE-D because of discontinuing olanzapine use and supersensitivity psychosis is discussed.

    One size does not fit all in psychotherapy: Understanding depression among patients of Turkish origin in Europe
    (Turkish Neuropsychiatric Society, 2016-03) Balkır Neftçi, Nazlı; Barnow, Sven
    Over the last decades, Europe has become an immigration country hosting an estimated 56 million international immigrants. Yet, a large amount of literature suggests that migration is associated with a higher risk of common mental disorders, such as depression and anxiety. As representatives of one of the largest immigrant groups in Europe, various studies have shown that Turkish immigrants exhibit a higher prevalence of depression and anxiety disorders than do the background population. Nevertheless, it is also well demonstrated that this particular patient group is more likely to terminate treatment prematurely and displays lower rates of treatment compliance than their native counterparts. This reluctance for service utilization might be partially because of the fact that people from non-Western ethnocultural backgrounds (e.g., Turkey) often have a different notion and comprehension of mental health and illness as compared with those of the people from Western societies. Such mismatch often results in discrepancies between the needs and expectations of immigrant patients and clinicians, which attenuate the communication and effectiveness of treatment and lead to unexplained high dropout rates. To provide continued provision of culture-sensitive, high quality, evidence-based mental health care, the advancement of researches exploring such sociocultural differences between the patients’ and the clinicians’ notions of mental health must occur. In response to these problems, the current review aims to explore the interplay between culture and mental processes that associate with the etiology, maintenance, and management of depression among Turkish immigrant patients. This is to inform clinicians regarding culturespecific correlates of depression among Turkish patients to enable them to present interventions that fit the needs and expectations of this particular patient group.

    Independent contributions of early positive parenting and mother-son coercion on emerging social development
    (Springer, 2018-06) Akçinar Yayla, Berna; Shaw, Daniel S.
    In the current study, we explored associations between parent-child coercion and positive parenting in the toddler period in relation to children's social-behavioral development during the school-age period. The data were drawn from the Pitt Mother & Child Project, a sample of 310 low-income, ethnically diverse boys. Drawing on tenets of both attachment and social learning theory, it was hypothesized that coercive mother-son interaction would lead to reductions in positive maternal parenting in the toddler period, and that both positive parenting and mother-son coercion in the toddler period would contribute to children's conduct problems at school entry and lower social skills and peer rejection in middle childhood. The results were largely confirmed, such that mother-son coercive interaction at 18 months was related to decreases in positive parenting at 24 months. Additionally, mother-son coercive interaction and positive parenting at 24 months were linked to child conduct problems at age 5, which in turn predicted child social skills and peer rejection during middle childhood. In addition to indirect effects through child conduct problems, mother-son coercion continued to be independently related to school-age peer rejection. The findings are discussed with respect to the importance of early coercive interactions in the growth of child social-behavioral development from early to middle childhood.
