Background: Families of patients are faced with stressors in the intensive care unit (ICU) that cannot be controlled sometimes. Having hope is one of the strategies for obtaining self-control in patients’ families, which deals with such situations.

Objective: The purpose of this study was to design and validate a questionnaire of hope for family members of patients hospitalized in intensive care units.

Methods: This study was conducted for family members of patients hospitalized in the intensive care units of Kurdistan and Tehran provinces, in Iran, between the years 2015-2016. In this study, 126 family members were selected using convenience sampling. The study was conducted using a questionnaire of hope scale for family members of patients hospitalized in intensive care units and demographic characteristics. During the study, construct and criterion validity of the tool was determined. The Reliability was determined using internal consistency and test-retest coefficient. Data were analyzed through factor analysis, correlation coefficient and Cronbach's alpha. Construct validity of the scale was analyzed using exploratory factor analysis (EFA). 

Results: Participants in this study included 12 family members of patients hospitalized in the intensive care units. Cronbach's alpha coefficients obtained from analysis of questionnaires completed by family members of patients was 0.916. Cronbach's alpha under the first scale (compatibility) was 0.898, Cronbach's alpha of the second subscale (self-confidence) was 87%, Cronbach's alpha under the third subscale (Sense of responsibility) was 0.770. The fourth subscale (Looking to the future) was 0.571. Pearson correlation coefficients between the scores obtained from two family members responses to the hope scale were 0.939 which showed that scale stability was average. As a result, exploratory factor analysis, four factors were found that were named according to the statements of each group. 

Conclusion: Consistency coefficients between the two tests was 0.939 that the stability over time the questionnaire was confirmed. A questionnaire of hope in the intensive care unit can measure different dimensions of hope to the families of these patients and help to improve the care of these patients. Validity and reliability of "scale for hope of families of these patients" was appropriate and it could be used to measure hope in families of these patients.

Ethics of Publishing Case Reports: Do We Need Ethics Approval and Patient Consent?

An editorial by Dr. Mehrdad Jalalian

The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.


To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here
