    Development and psychometric validation of the pre-earthquake illusion of control perception scale
    (Bmc, 2026) Celebi, Ismet; Gokkaya, Emrah; Demirbilek, Omer
    Background Earthquakes are highly destructive, and their impact depends largely on prior preparedness. Beyond knowledge and experience, psychological perceptions-especially the illusion of control, the unrealistic belief that one can influence uncontrollable events-can reduce motivation to prepare and weaken disaster readiness. This study aimed to develop a valid and reliable instrument to measure adults' pre-earthquake illusion of control. Methods The scale development process followed established psychometric procedures, including content validation, item analysis, Exploratory Factor Analysis (EFA), and Confirmatory Factor Analysis (CFA). Data were collected from 406 participants aged 18 and older. Result EFA revealed a two-factor structure explaining 59.56% of the total variance, consisting of Perceived Control and Preparedness and Avoidance of Earthquake-Related Anxiety. CFA supported this structure with acceptable fit indices (CFI = 0.944, RMSEA = 0.072). Reliability analyses demonstrated high internal consistency for the total scale (alpha= 0.886) and both subdimensions. Conclusion The resulting 12-item scale demonstrates promising psychometric properties within the present sample and provides an initial instrument for assessing pre-disaster control illusion perceptions in the context of earthquakes. The scale may provide a useful tool for future research examining cognitive factors influencing disaster preparedness and risk communication.

    Effect of Disaster Awareness Education on General Disaster Preparedness Beliefs: A Quasi-Experimental Study
    (Cambridge Univ Press, 2025) Demirbilek, Omer; Aslan, Ramazan
    Objective This study examines the impact of a disaster awareness education program on general disaster preparedness beliefs in T & uuml;rkiye, utilizing the Health Belief Model as a theoretical framework.Methods A quasi-experimental, single-group design with pre-test, post-test, and follow-up measurements was employed. Participants were enrolled in a Disaster Awareness Education course at a Public Education Center. Data were gathered using a demographic questionnaire and the General Disaster Preparedness Belief (GDPB) Scale. Repeated measures ANOVA was conducted to assess changes over time.Results Significant improvements were observed in perceived susceptibility, perceived severity, perceived barriers, cues to action, and self-efficacy following the intervention. While male participants showed no significant changes, female and middle-income participants experienced substantial improvements. Perceived susceptibility initially increased but reverted to baseline at follow-up. Perceived severity decreased and remained low, whereas perceived barriers declined post-education but were not sustained. Cues to action showed a steady increase, suggesting ongoing motivation. Self-efficacy improved significantly and was maintained over time.Conclusions Disaster education has a positive impact on general disaster preparedness beliefs. Tailored interventions may be especially beneficial for specific demographic groups such as males and lower-income individuals. It is recommended that future studies investigate the mechanisms underlying demographic disparities in educational impact, particularly among male and low-income participants.

    Emotional disturbances and psychological resilience among earthquake survivors in temporary shelters: assessing the role of life satisfaction
    (Springernature, 2026) Gokkaya, Emrah; Topal, Mehmet Hanefi; Demirbilek, Omer; Baydemir, Muhammed Bedir
    Objective This study aims to examine the levels of emotional disturbances, psychological resilience, and life satisfaction among earthquake survivors residing in temporary shelters in Hatay province following the 2023 Kahramanmara & scedil;-centred earthquakes. Additionally, it seeks to identify the critical role of life satisfaction. Methodology This study employs a quantitative, correlational research design with data collected from 408 participants selected through purposive sampling. Participants range in age from 18 to 70 years. Data collection utilizes face-to-face surveys administered through a demographic information form, the Brief Psychological Resilience Scale (BPRS), the Satisfaction with Life Scale (SWLS), and the Depression Anxiety Stress Scales-21 (DASS-21). Analyses are performed using JASP (v.0.19.3.0), incorporating descriptive statistics, independent samples t-tests, ANOVA, mediation, and moderation analyses. Findings The results reveal that female and younger earthquake survivors report significantly higher levels of emotional disturbances. Emotional disturbances negatively predict psychological resilience, whereas life satisfaction positively predicts psychological resilience. No meaningful relationship emerges between emotional disturbances and life satisfaction. Moderation analyses demonstrate that life satisfaction significantly moderates the relationship between stress, anxiety, depression, and psychological resilience. However, mediation analyses indicate that neither life satisfaction nor emotional disturbances mediate the relationship between psychological resilience and the other Variables. Conclusion According to the research findings, depression, anxiety and stress negatively affect psychological resilience, while life satisfaction plays a role in increasing vulnerability rather than fulfilling its expected buffering function; it shows that groups such as women, younger generations, and single individuals exhibit higher levels of mood disorders and lower levels of psychological resilience; and that the relationship between educational level and psychological resilience is shaped by cultural context. Therefore, in disaster management processes, rather than focusing solely on increasing life satisfaction, developing goal-oriented psychosocial interventions aimed at reducing mood disorders, community solidarity programs, and psychological support services integrated into the insurance system are critical for sustainable disaster resilience. This study highlights a crucial paradox for post-disaster mental health: life satisfaction, rather than buffering the impact of emotional distress, can unexpectedly increase psychological vulnerability.

    Operational Movement Strategies of Volunteer Search and Rescue Teams: February 6, 2023 Kahramanmaras Earthquakes Experience
    (Afet ve Acil Durum Yonetimi Baskanligi (AFAD), 2025) Kocer, Musab Suleyman; Demirbilek, Omer
    Disasters are sudden and devastating events that require effective search and rescue (SAR) activities to reduce loss of life and property. This study examines the factors influencing volunteer SAR teams’ decisions to stay, relocate, or withdraw from operational areas during the 2023 Kahramanmaraş earthquakes. Using a phenomenological design, semi-structured interviews were conducted with 13 team leaders from seven NGOs, and the data were thematically analyzed. Findings indicate that these decisions are shaped not only by operational needs but also by psychological factors, organizational structure, team dynamics, and environmental threats. The study contributes to understanding volunteer decision-making, strengthening coordination, and enhancing professionalization in disaster volunteerism. © (2025), (Afet ve Acil Durum Yonetimi Baskanligi (AFAD)).

    The Macroeconomic Effects of Earthquakes in Turkey and Sustainable Economic Resilience: A Time Series Analysis, 1990-2023
    (Mdpi, 2025) Ulger Danaci, Ozlem; Gokkaya, Emrah; Yavuz, Kemal; Demirbilek, Omer
    This study examines the macroeconomic impacts of major earthquakes in T & uuml;rkiye using annual data from 1990 to 2023. Despite growing global interest in disaster economics, evidence on how large seismic events shape national economic performance over extended periods remains limited, particularly in emerging economies. Using data from the World Bank, the Central Bank of the Republic of T & uuml;rkiye, and the Disaster and Emergency Management Authority, the analysis incorporates real gross domestic product, gross fixed capital formation, consumer prices, and export capacity. A dummy variable identifies years with high-fatality earthquakes. After confirming stationarity, Johansen cointegration and a Vector Error Correction Model were applied. Results indicate that earthquakes exert a statistically significant negative influence on long-term economic growth. Based on the log-level specification, the long-run equilibrium level of real gross domestic product in earthquake years is approximately 45 percent lower than in non-earthquake years. Investment, price stability, and trade capacity support long-term growth. Model diagnostics confirm stability, normality, and no autocorrelation. These findings highlight the structural economic vulnerabilities created by major earthquakes and underscore that disaster risk reduction and resilient infrastructure policies must be integral components of sustainable growth strategies. The study contributes updated national time-series evidence from a structurally fragile context.
