Introduction: The expedited COVID-19 vaccine has challenged people’s belief and perception of its effectiveness. The purpose of this study was to identify whether knowledge related to Covid-19 and perception of effectiveness of Covid-19 vaccine would predict health-care workers’ willingness to take the vaccine. Methods: A cross-sectional design using a convenience sampling technique was used to collect data from 302 HCWs. HCWs targeted included all those working at healthcare settings in Jordan. Data collected regarding knowledge related Covid-19 and perception of effectiveness of Covid-19 vaccine. Data collected using a self-administered questionnaire. Results: HCWs have moderate to high level of knowledge related to vaccines of Covid-19 and its effectiveness. High level of willingness to take the vaccine was also observed among HCWs. Those with higher level of knowledge and positive perception of effectiveness of Covid-19 vaccine are more likely to take the vaccine (p < .05); however, not highly influential (R2 = 27%). Demographic characteristics have not been found to influence HCWs’ decision to take the vaccine. Conclusion: There is a need to enhance positive perception of effectiveness of Covid-19 vaccine among health professionals through appropriate education and procedures.

Introduction: Schizophrenia is one of the most serious and disabling psychiatric disorders which affect the overall patients’ life and predispose them to suffer from loneliness. The purpose of this study was to identify levels and correlates of loneliness among patients with schizophrenia. Methods: A cross-sectional design was applied to collect data about loneliness; social support from friends, family members, and significant others; satisfaction with life; and demographic and illness-related variables. A semi-structured interview with patients was employed to collect data from 230 in-patients with schizophrenia receiving treatment at a large psychiatric hospital. Results: Level of loneliness was 52.6 out of 80. Higher rates of patients (66.5%) were found within the category of moderate to high level of loneliness. Loneliness was found to be highly associated with low satisfaction with life, low social support from friends, and longer duration of treatment. Loneliness was higher in female patients, those living with other people in the house, and those with a history of drug/substance abuse. Conclusion: Loneliness was found to be in a moderate to high level. Therefore, there is a crucial need for interventional programs that aimed to decrease the feeling of loneliness and enhance satisfaction with life and social support from others among patients with schizophrenia.
