Article Citation - WoS: 2Citation - Scopus: 2Effects of Covid-19 Lockdowns on Social Distancing in Turkey(Oxford University Press, 2022) Bilgel, FıratThis paper elucidates the causal effect of lockdowns on social distancing behaviour in Turkey by adopting an augmented synthetic control and a factor-augmented model approach for imputing counterfactuals. By constructing a synthetic control group that reproduces pre-lockdown trajectory of mobility of the treated provinces and that accommodates staggered adoption, the difference between the counterfactual and actual mobility of treated provinces is assessed in the post-lockdown period. The analysis shows that in the short run following the onset of lockdowns, outdoor mobility would have been about 17–53 percentage points higher on average in the absence of lockdowns, depending on social distancing measure. However, residential mobility would have been about 12 percentage points lower in the absence of lockdowns. The findings are corroborated using interactive fixed effects and matrix completion counterfactuals that accommodate staggered adoption and treatment reversals.Article Citation - WoS: 3Citation - Scopus: 3Effects of Vaccination and the Spatio-Temporal Diffusion of Covid-19 Incidence in Turkey(John Wiley and Sons Inc, 2022) Bilgel, Fırat; Karahasan, Burhan CanThis study assesses the spatio-temporal impact of vaccination efforts on Covid-19 incidence growth in Turkey. Incorporating geographical features of SARS-CoV-2 transmission, we adopt a spatial Susceptible–Infected–Recovered (SIR) model that serves as a guide of our empirical specification. Using provincial weekly panel data, we estimate a dynamic spatial autoregressive (SAR) model to elucidate the short- and the long-run impact of vaccination on Covid-19 incidence growth after controlling for temporal and spatio-temporal diffusion, testing capacity, social distancing behavior and unobserved space-varying confounders. Results show that vaccination growth reduces Covid-19 incidence growth rate directly and indirectly by creating a positive externality over space. The significant association between vaccination and Covid-19 incidence is robust to a host of spatial weight matrix specifications. Conspicuous spatial and temporal diffusion effects of Covid-19 incidence growth were found across all specifications: the former being a severer threat to the containment of the pandemic than the latter.Conference Object Interpersonal Factors and Suicidal Behavior During Covid-19 in Young Adults in Turkey(Hogrefe, 2023) Çalışkan, Neslihan; Şahin, Banu Çankaya; Caine, Eric D....Article Citation - WoS: 44Citation - Scopus: 45Population Density Index and Its Use for Distribution of Covid-19: a Case Study Using Turkish Data(Elsevier, 2020) Başer, OnurSince March 2020, many countries around the world have been experiencing a large outbreak of a novel coronavirus (2019-nCoV). Because there is a higher rate of contact between humans in cities with higher population weighted densities, Covid-19 spreads faster in these areas. In this study, we examined the relationship between population weighted density and the spread of Covid-19. Using data from Turkey, we calculated the elasticity of Covid-19 spread with respect to population weighted density to be 0.67 after controlling for other factors. In addition to the density, the proportion of people over 65, the per capita GDP, and the number of total health care workers in each city positively contributed to the case numbers, while education level and temperature had a negative effect. We suggested a policy measure on how to transfer health care workers from different areas to the areas with a possibility of wide spread.Article Citation - WoS: 2Citation - Scopus: 2Social Connectedness and Mental Health Before and During the Covid-19 Pandemic in a Community Sample in Korea(Public Library of Science, 2023) You, Sungeun; Moon, Hyejoo; Lee, Sojung; Şahin, Banu Çankaya; Caine, Eric; Ko, JisuThis study compared social connectedness patterns and examined the relationships between objective or subjective social connectedness and mental health before and during the COVID-19 pandemic among community dwelling adults in South Korea. An identical online survey was administered at two time points, in 2019 prior to the onset and again in 2021. Objective (network diversity and network size) and subjective (thwarted belongingness and perceived burdensomeness) social connectedness were measured along with positive and negative indices of mental health (depression, suicidal behavior, happiness, and life satisfaction). The results indicated that among social connectedness indices perceived burdensomeness were significantly higher during the COVID-19 pandemic compared to the prior period, while network size was smaller. Subjective social connectedness was associated with all aspects of mental health consequences, either positive or negative. Among objective social connectedness, only network diversity was significantly associated with increased happiness and life satisfaction, and objective social connectedness was not associated with depression and suicidal behavior. These associations did not differ across the two time periods. The findings, both before and during the pandemic, indicated that network diversity is an important factor for positive indices of mental health and that efforts to increase subjective social connectedness are needed to decrease the risk of depression and suicidal behavior.Article Citation - WoS: 8Citation - Scopus: 10Workers' Individual and Dyadic Coping With the Covid-19 Health Emergency: a Cross Cultural Study(Sage, 2022) Donato, Silvia; Brugnera, Agostino; Manzi, Claudia; Reverberi, Eleonora; Aksu, Ayça; Molgora, Sara; Adorni, RobertaThe aim of this study was to examine workers' psychological distress during the COVID-19 pandemic as a function of their individual coping, dyadic coping, and work-family conflict. We also tested the moderating role of gender and culture in these associations. To achieve this aim, we run HLM analyses on data from 1521 workers cohabiting with a partner, coming from six countries (Italy, Spain, Malta, Cyprus, Greece, and Russia) characterized by various degrees of country-level individualism/collectivism. Across all six countries, findings highlighted that work-family conflict as well as the individual coping strategy social support seeking were associated with higher psychological distress for workers, while the individual coping strategy positive attitude and common dyadic coping were found to be protective against workers' psychological distress. This latter association, moreover, was stronger in more individualistic countries.
