Abstract
Heart failure not only affacts the patients but also their families and social networks. This study was conducted to evaluate the development & psychometric properties of the Social Dignity Questionnaire (SDQ) in heart failure patients. This study is an exploratory research of questionnaire design type. Twenty two patients with class II to IV heart failure (New York Heart Association Functional Classification) were chosen through purposive sampling from selected hospitals of Tehran, and semi-structured interviews were conducted with them. Qualitative content analysis was performed to analyze the interviews. The primary items were developed based on the findings obtained from the interviews, literature and designed questionnaires about social dignity. Content validity and construct validity were determined in 130 patients with heart failure. The data were analyzed using SPSS version 19. Through face validity and content validity analysis, 16 out of 101 primary items were removed. As a result of exploratory factor analysis, 2 items with factor loading less than 0.5 were deleted, and 6 were removed due to inclusion in other factors. The following five factors were extracted: family communication and support, social communication and support, health care communication and support, burden to others (physical, emotional and social), and burden to others (economic). Reliability of the Social Dignity Questionnaire (SDQ) was calculated to be 0.97 by using Cronbach’s alpha coefficient, and 0.99 by using split-half method.Considering the acceptable validity and reliability of the questionnaire in the present study, its application can be useful in planning support for patients and improving their treatment and care. The questionnaire may also be helpful in conducting further research related to dignity in different patients

Abstract
Respect for the inherent dignity of human beings means respecting their basic rights in different environments, and this has an important role in studies and discussions about health care. This study was conducted on the development and psychometric properties of the Inherent Dignity Questionnaire (IDQ) in heart failure patients. The present study is a methodological research for designing a questionnaire. First, 22 patients with class II to IV heart failure were chosen by purposive sampling from patients of Hazrate Rasoule Akram, Imam Hossein and Shariati hospitals of Tehran, and semi-structured interviews were conducted on ethical issues until data saturation was achieved. A qualitative content analysis was carried out to analyze the interviews. Then, based on the findings obtained from the interviews, literature, and the designed questionnaires about inherent dignity, 39 items associated with inherent dignity in heart failure patients were developed. The face validity of the questionnaire was determined. To measure the content validity of the questionnaire, opinions of 12 experts were used considering Content Validity Index (CVI), Content Validity Ratio (CVR) and Lawshe table. To assess construct validity of the IDQ, exploratory factor analysis and to determine the reliability of the questionnaire, internal consistency with Chronbach’s alpha coefficient and split-half method were used on 130 patients with heart failure. The data were analyzed using SPSS version 19.Through face validity and content validity analysis, 4 out of the 39 primary items were removed, leaving 35 items. Through exploratory factor analysis, 11 items with factor loading less than 0.5 were removed and the IDQ was created with 24 items and three factors (9 items on the first factor, 8 items on the second factor and 7 items on third factor). These factors were: "inherent dignity in family", "inherent dignity in the community" and "inherent dignity in health care environments". Reliability of the Social Dignity Questionnaire (SDQ) was calculated to be 0.94 by using Cronbach's alpha coefficient, and 0.96 by using split-half method.Results of this study showed that the IDQ is adequately valid and reliable. Therefore, using this questionnaire can be beneficial to planning support for patients and improving their treatment and care and doing further research related to dignity in different patients.

Abstract
Faculty members and researchers bear the greatest responsibility for producing scientific research outputs due to the nature of their profession and mission. Given the role of ethical principles in ensuring evidence-based research, their impact on research utilization in society, and the importance of scientific evaluations, this study was conducted to design and psychometrically evaluate a questionnaire on factors related to unethical research practices among researchers. This cross-sectional study was conducted in 2024 among faculty members and researchers at medical sciences universities in Iran. Based on a preliminary qualitative study, 40 items were initially generated for the questionnaire. The validity of the questionnaire was assessed through face validity, content validity (CVR, CVI), and criterion validity (divergent and convergent). Besides, exploratory factor analysis (EFA) and reliability testing (Cronbach's alpha) were performed. Data were analyzed using descriptive statistics, Pearson correlation coefficient, and Student's t-test. During the content validity assessment, 11 researchers evaluated the items. Applying cutoff scores of 0.59 for CVR and 0.79 and above for CVI, 16 out of 40 items were removed, retaining 24 items. Exploratory factor analysis revealed five key factors, including “researchers’ irresponsible and unprofessional behaviors and beliefs”, “inefficient basis for competition and career advancement among researchers”, “lack of awareness and up-to-date knowledge among researchers”, “inefficient organizational culture and policies”, and “lack of supervision over researchers and research”. Descriptive findings indicated significant differences in the mean scores of factors associated with unethical research practices of researchers by gender (P=0.002) and organizational position (P=0.004), but not by education level. The findings from this study confirmed the strong psychometric properties of the questionnaire on factors related to unethical research practices.
