COVID-19 related knowledge and mental health: Case of Croatia

This dataset refers to the data of 1244 people, aged from 18 to 72 years. Data concerns socio-demographic and epidemiological information and results to 3 questionnaires, as follows. The authors of the study used the information available on WHO website to examine knowledge about COVID-19. Eight questions were used to examine the participants knowledge about coronavirus, 5 of them were multiple choice questions and 3 questions were true/false type questions. Various types of factor and reliability analyzes were performed to see whether a linear combination of the results could be used, but the results did not support this. It was then decided to consider each question as separate, examining their relationship to the research variables. Participants were divided in two groups for each of the 8 questions according to their answers. More specifically, if a participant scored correctly on question 2, but incorrectly on question 3 he was put in the ‘informed’ group for question 2 and the ‘uninformed’ group for question 3. The The Hospital Anxiety and Depression scale (HADS) (Zigmond and Snaith, 1983:Pokrajac-Bulian et al. 2015) is divided in the Anxiety subscale and the Depression subscale. Both subscales contain 7 items. Participants were divided into three categories according to the authors. The Optimism-Pessimism scale (OPS) (Penezić,2000) was to measure positive and negative expectations of future activities outcome. This scale consists of the Optimism subscale which has 6 items and the Pessimism subscale which has 8 items.
