The Effect of Nudging on Compliance with Individual Prevention Measures against Covid-19
Nudging has often been suggested as a means to promote health care efficiency and effectiveness by influencing behavior without restricting choice; its usefulness, however, has not been adequately assessed. We examined the effect of an altruistically framed awareness message about the novel coronavirus on the intention to comply with individual prevention measures against infection. A total of 425 Greek postgraduate students, which were randomly …

Determining dimensions of job satisfaction in healthcare using factor analysis
Job satisfaction is a multidimensional construct that encompasses different facets of satisfaction. There is a lack of consensus as to which factors are more important and a researcher may find satisfaction with some factors while at the same time dissatisfaction with others. Our findings are significant for improving our understanding of the nature and assessment of job satisfaction in the Greek healthcare context, providing a more stable ground…

The analysis includes descriptive and inferential statistics, reliability and validity tests, as well as structural equation modeling to evalua…
Health-Related Quality of Life of the Roma in Greece
The aim was to assess the health-related quality of life (HRQL) of the Roma and further to detect the significant determinants that are associated with their HRQL. The cross-sectional study involved 1068 Roma adults living in settlements (mean age 36). HRQL was measured by the Greek version of SF-36 Health Survey and further socio-demographic characteristics (sex, age, marital status, education, permanent occupation etc.) and housing conditions (…
Investigating Unmet Health Needs in Primary Health Care Services in a Representative Sample of the Greek Population
Unmet health care needs are determined as the difference between the services judged necessary and the services actually received, and stem from barriers related to accessibility, availability and acceptability. This study aims to examine the prevalence of unmet needs and to identify the socioeconomic and health status factors that are associated with unmet needs. A cross-sectional study was conducted in Greece in 2010 and involved data from 1,00…
Comparative validation of the Womac osteoarthritis and Lequesne algofunctional indices in Greek patients with hip or knee osteoarthritis
Psychometric and factor analytic evaluation of the 15D health-related quality of life instrument
Terrorism, Talking and Transformation
Objectives. In this prospective study, we intend to establish the psychometric properties of ICOAP for its use in studies involving the Hellenic population. Methods. SF-36 Health Survey was used as a standard against ICOAP scores from a sample of 89 patients (mean age: 71.07, 69 females) with hip and knee OA pain who underwent 2 treatment cycles of 4 intra-articular injections of sodium hyaluronate, separated by a 12-week medication-free time int…
Physician Consultations According to Different BMI Levels of the Greek General Population
Obesity constitutes a global epidemic which is rapidly becoming a major public health problem in many parts of the world, threatening peoples' health and quality of life. The aim of our study was to estimate the prevalence and impact of overweight and obesity on physician consultations and frequency of use and furthermore, to investigate whether physician consultations in each of the groups defined by BMI level correspond to the need for care imp…
Do place of residence and ethnicity affect health services utilization? evidence from greece
Although health care needs were the main determinant of health services utilization in both the urban and rural population, socio-economic and ethnic differences also seem to contribute to the inequities observed in some types of health services use, favouring the better-off. Such findings provide important information to policy makers, which attempt to reduce inequalities in health care according to place of residence and ethnicity
Self-efficacy and Oral Hygiene Beliefs about Toothbrushing in Dental Patients
Building on previous research on psychosocial variables associated with oral hygiene behavior, this study examined the ability of Health Belief Model variables (perceived benefits, barriers, susceptibility, severity) and self-efficacy beliefs about toothbrushing to inform prevalence of dental caries and toothbrushing frequency. To accomplish this goal, a sample of 125 dental patients completed self-report questionnaires and provided data on demog…
Socioeconomic inequalities in general and psychological health among adolescents
Socioeconomic inequalities exist in this period of life but are more easily demonstrated with more subjective socioeconomic indicators, especially for the psychological dimension of health
Factors Affecting Use of Preventive Tests for Cardiovascular Risk among Greeks
Data from a Greek national representative sample was used to investigate socio-demographic, self-perceived health, and health risk factors that determine the use of cardiovascular preventive tests (blood pressure, cholesterol and blood glucose). Chi-square and logistic regression analyses were used (p < 0.05). Older age, marriage, regular family doctor and chronic diseases increased the likelihood of receiving preventive tests, whereas low educat…

Comparing SF-6D and EQ-5D utilities across groups differing in health status
Predictors of health-related quality of life in type II diabetic patients in Greece
The findings could have implications for health promotion in rural medical practice in Greece. In order to preserve a good HRQOL, it is obviously important to prevent diabetes complications and properly manage concomitant chronic diseases. Furthermore, the gender difference is interesting and requires further elucidation. Modifying screening methods and medical interventions or formulating educational programs for the local population appear to b…
