Introduction: The preparedness of families for the disasters can set auspicious grounds for the preparedness of the whole society. In Iran health system, Household Disaster Preparedness Index (HDPI) that is composed of 15 items is applied for assessing the household preparedness in disasters. This study was conducted to investigate the reliability and validity of this index.
Methods: In order to investigate the HDPI reliability, we two methods, namely internal consistency and stability determination, are. In order to investigate HDPI validity, we examined the face validity, content validity and construct validity. To do so, besides interviewing with the experts and family heads, 200 families were selected based on multistage cluster sampling method from amongst a study population that included the families in all the counties in Isfahan Province. Use has been made in content validity investigation of both qualitative and quantitative methods; and, in investigating the construct validity, exploratory factor analysis was the method of choice.
Results: The amount of HDPI internal consistency was calculated 0.786 which is in an acceptable range. HDPI stability, as well, was computed 0.98 using the test-retest method which is also in an optimal level. Therefore, it can be stated that HDPI enjoys the required reliability. Investigation of HDPI face validity indicated that the families have problems in perceiving some of the items of this index. The experts presented suggestions for improving the HDPI content validity following the qualitative investigation of the content validity. In the investigation of the content validity ratio (CVR), all the items, except the ones numbered 1, 3 and 4 were in an acceptable range; however, the investigation of the content validity index (CVI) indicated that only the validity of the items numbered 12 and 13 was acceptable in terms of all the three scales of relevancy, clarity and simplicity. To determine the construct validity, we used exploratory factor analysis to extract five factors (subscales), namely reduction of vulnerability, planning for disasters, family empowerment, procurement of resources for disasters and specialized programs. The internal consistency of these subscales indicated that only the internal consistencies of the first and the second factors were in an acceptable range.
Conclusion: The present study revealed that although HDPI was a reliable measure, it did not enjoy the required validity for assessing the household preparedness in disasters.

Background: Identification of the influencing factors of nursing students’ clinical judgment (CJ) facilitates the achievement of this important educational outcome. However, no tool is so far designed to assess it in the field of clinical education in Iran.Objectives: The current study aimed at designing sequential exploratory mixed method in 3 phases.Methods: It was a mixed method study. The 1st phase included reviewing literature, analyzing the relevant studies in Iran, and a qualitative content analysis. In the 2nd phase, validity and reliability of the tool were investigated.Results: In the study, after assessing the face, content, and construct validity, 4 factors and 38 items obtained. Content validity ratio (CVR) ranged from 0.45 to 1.00 and content validity index (CVI) ranged from 0.6 to 1.00. Internal consistency of the total scale was good with Cronbach’s alpha coefficient 0.92, and intraclass correlation coefficient (ICC) was 0.95 that indicated good stability. In the construct validity by exploratory factor analysis, the Kaiser-Meyer-Olkin (KMO) index was higher than 0.90 and also the Bartlett test of sphericity was significant (P value < 0.001). Concerning the cumulative percent of the variance, the 4 factors determined 44.8% of the total variance.Conclusions: The developed questionnaire in the current study was a suitable tool to assess the factors influencing the CJ of undergraduate nursing students.

Background: Clinical judgment (CJ) is a complex process and is one of the most important concepts in the domain of education of the nursing students. Despite the special importance of its concept in nursing, this term still has not created an equal perception in the minds of many experts in the nursing education and no study has been done in order to define and explain this concept by concept analysis of the “CJ” in the educational domain.Objectives: The current study was done with the purpose of determining dimensions and features of this concept in the domain of clinical education of nursing students in Iran.Methods: The design of this study is qualitative with concept analysis method and hybrid model approach. It was done in three phases that were described by Walker and Avant. In the theoretical stage, reviews on the related and valid articles were accomplished. The articles were assessed and analyzed in order to present the working definition. In the stage of field work, the interview was done with 17 participants including 7 nursing students, 6 teachers, and 4 clinical instructors. In the final stage, the general analysis was done and the antecedents, attributes, and the consequences of the concept were extracted.Results: According to the final analysis, CJ for the nursing students is a cognitive and reasoning process, in order to achieve which, the nursing students by guidance of teachers in a secure clinical environment, assess the patients’ needs, interpret, and evaluate the patients’ response to the clinical practice and then reflect and perform the critical evaluation of the patients’ conditions. In the meanwhile, making effective clinical decisions, increasing the trust of patient and quality of care, the necessary conditions for the promotion of their professional competence will be provided.Conclusions: In the concept analysis of CJ, some of the needed conditions for CJ in the nursing students have not been reported in the studies.
