Methods The study used a mixed-method design. In Phase 1, qualitative methods for developing the questionnaire were employed, including literature review, focus-group discussion, expert evaluation, and pre-testing. During Phase 2, quantitative methods were employed for establishing the construct validity of the questionnaire. In Phase 1, experts from departments like emergency medicine, medicine, obstetrics and gynecology, psychiatry, trauma, anesthesia, and critical care unit participated. For Phase 2, data were collected from 213 participants; mean age (30.48±5.95) in metropolitan cities. Results The questionnaire consists of 37 items in five domains: (A) Forms of violence, (B) Impact of violent incidences, (C) Reporting of incidence, (D) Mitigation strategies, and (E) Risk factors. The Cronbach’s alpha value of the questionnaire is 0.86, suggesting an excellent internal consistency. Conclusion A reliable and valid tool for gathering information regarding WPV in the healthcare system from around the world has been developed. The tool can be used to study the elements that may contribute to violence and its consequences, which will help policymakers curate various mitigation methods to safeguard WPV victims. Workplace violence (WPV) in the healthcare sector is a global concern and has become unfortunate in different parts of the world [1] . Several patients, doctors, organizational and society-related factors lead to verbal and physical forms of violence, causing a significant impact on healthcare workers' (HCWs) social and mental well-being. The global prevalence of WPV in healthcare is estimated to be up to 80 percent [2] . The actual figure maybe even worse, as many incidents are ignored and unreported [3, 4] . The need of the hour is to evolve mitigation strategies to reduce workplace violence and ensure safe working conditions for healthcare personnel, as a well-functioning healthcare sector is essential to enhance the quality of life of citizens anywhere in the world. Researches conducted in different parts of the world have studied different aspects of the WPV in healthcare settings. Most of them have used non-validated semi-structured interview techniques, making it challenging to compare different studies [5] . Most of the available validated questionnaires are not easy to administer and suffer from the limitation of low psychometric properties. They are unable to capture various domains comprehensively as one single scale [6] [7] [8] [9] [10] . This study was conducted to develop and validate a comprehensive, easy-to-administered tool that could 1 2 2 3 4 5 6 7 8 2 assess all relevant domains of WPV in a healthcare setting (forms of violence, impact, underreporting, mitigation strategies, and risk factors) that would help in a comprehensive evaluation. This questionnaire was developed and validated using a standard scientific approach [11] [12] [13] . This included a thorough study of the literature, in-depth interviews, focus group discussions, expert opinions, pilot testing, and validation. The study was conducted after prior approval from the Institute Ethics Committee of The All India Institute of Medical Sciences, New Delhi, India (IEC-844/06.12.2019, RP-46/2020). All subjects involved in the research provided informed consent for the same. The process of questionnaire development is given in Table 1 . Step Nature of activity Step 1: Literature Review An in-depth literature review was done by using search string (violence OR aggression) AND(doctor OR physician OR "general practitioner" OR Surgeon OR resident OR intern" OR clinicians OR "health care) AND (workplace) AND (determinants OR predictor) AND (intervention* OR strategy* OR prevent*) in PubMed and Wiley from looking for relevant studies done over the past ten years, in the English language. Five hundred fifty-three articles were screened, from which 27 relevant articles were selected. This helped identify various domains for the questionnaire like types/ forms of violence, reporting of violence, risk factors of violence, the impact of violence, and mitigation strategies under which 45 items were generated. The investigators performed five FGDs, each session having 6-8 participants. The sessions were organized over an online platform with the doctors and other healthcare workers. As per the literature review and collaboration with an expert (clinical psychologist), the FGD guide was developed, which included openended questions to help participants explore their viewpoints, practices, and issues. Active involvement was encouraged, and the discussion included topics such as types/forms of violence, reporting of violence, risk factors of violence, the impact of violence, and different mitigation strategies which can be used to reduce workplace violence. Later on, five in-depth interviews were also conducted to gain more information on this issue. The resulting data were qualitatively evaluated, and new items were added to the tool as a result. The focus groups and in-depth interviews resulted in the addition of 12 items. A set of 57 questions was created based on the literature review, focus group discussions, and in-depth interviews. The survey items were prepared in an easy-to-understand format, eliminating the double negatives. A team of eight specialists from various areas (emergency medicine, medicine, gynecology, psychiatry, clinical psychology, and nursing) validated the developed tool for critical review, content, and face validity. All elements were assessed based on their need, clarity, and relevance. The feedback made necessary adjustments to the questionnaire: 11 items were eliminated at this stage. Following the approach mentioned above, a questionnaire draft was created and pre-tested on 12 doctors and other health care workers. The participants remarked on the items' need, relevance, and clarity. Six items were eliminated based on feedback and expert consultation, and necessary adjustments were made in four items to reduce ambiguity. During expert validation, the questionnaire's content validity was examined using qualitative and quantitative approaches. An expert panel of eight participants was invited to examine the questionnaire and comment on the necessity, relevance, and clarity of items in the qualitative validity. The items were changed in response to the input. A three-point scale (-1,0,+1) was used to grade the usefulness of items. Lawshe scores were used to compute appropriate Content Validity Ratio (CVR) values. To determine the relevance, clarity and simplicity of each item, a four-point Likert scale was used. Items with a 0.7 or less Content Validity Index (CVI) were eliminated, and those between 0.7-0.79 were altered as per the expert's opinion [14] . Expert review and pilot testing were conducted to achieve face validity from doctors and other healthcare workers belonging to different departments. A cross-sectional survey was conducted to validate the questionnaire. Participants, including doctors and other healthcare staff from various departments like emergency medicine, medicine, psychiatry, nursing, obstetrics, and gynecology, were recruited during August 2021; a convenience sampling method was used to recruit the participants. After receiving written informed consent, the investigators administered the questionnaire in online and offline mode, and responses were recorded on Google forms simultaneously. The demographic information of the participants was analyzed using descriptive statistics. The Kaiser-Mayer-Olkin (KMO) measure determines the adequacy of the sample and values greater than 0.5 suggest that the data is suitable for factor analysis. To discover domains of the questionnaire and establish construct validity, exploratory factor analysis with principal component extraction and varimax rotation with Kaiser normalization were employed. The internal consistency was measured using Cronbach's alpha. Its score of greater than 0.7 suggests that it has high internal consistency. IBM® SPSS® Statistics version 24.0 was used to analyze the data. Two hundred thirteen doctors and other healthcare staff working in different departments (emergency medicine, medicine, obstetrics and gynecology, and psychiatry) participated in this survey. The participants were aged 18-65 years (Mean=30.48; SD=5.08) with a slight male predominance (60.09% males). 92% of the participants were practicing in government hospitals, out of which 79% were residents of metropolitan cities. The socio-demographic details of the participants are given in Table 3 . It was observed that approximately 35% of the HCWs experience verbal altercations at their workplace daily, and 61% have never had any experience of physical violence. Due to episodes of violence at the workplace, 47% of the HCWS did not feel like working, which had a significant negative impact on their mental and psychological well-being. 33% of the participants did not feel comfortable reporting the incidence of violence to their authorities due to a lack of organizational support and believed no action would be taken. The questionnaire has good internal consistency (Cronbach's Alpha =0.86) [15] . Multicollinearity and singularity were checked through the inter-correlation matrix. The Kaiser-Meyer-Olkin value of the questionnaire is 0.816 with a good Bartlett test of sphericity (p < 0.01), which indicates sample adequacy. The total percentage of the variance explained by the questionnaire was 67.491%, indicating good construct validity. The developed questionnaire is a comprehensive and user-friendly tool with 37 items encompassing the problems related to WPV in the healthcare sector. It has five sections to assess the burden of the problem, the associated risk factors, and provide mitigation strategies to overcome it. The tool is developed on a Likert scale, which is beneficial in conducting comparative studies and can be used in different sociocultural settings. Section A comprises two items to assess the frequency of different types of violence experienced within healthcare settings. Apart from the prevalence, the spectrum of the various forms (verbal and physical) can also be assessed in this Section. Section B, comprising eight items, tries to analyze the impact of the episodes of WPV on the sufferers. The various components of an individual's life such as personal (sleep schedule, eating pattern, personal hygiene), family (such as relationships with parents, spouse, children), social (friends/colleagues'/ religious practice), and psychological well-being (increased aggressiveness, low self-esteem) are found be to significantly impacted due to such incidences. It is found that despite the significant impact of these incidents on the physical and psychological well-being of the victim, such occurrences go unreported. Section C, comprising 11 items, tries to assess the reasons for not reporting these violent episodes. Mitigation strategies that can be used to mitigate the episodes of violence at the workplace are assessed in Section D, which consists of 12 items. Lastly, Section E comprises five items to highlight the various risk factors that contribute to violence in healthcare settings. The most commonly available validated tool is made by WHO [16] . It has failed to gain popularity among researchers due to its vast and time-consuming nature. The scale is not very useful in conducting comparative studies. It fails to suggest mitigation strategies or ways to resolve the problem of WPV, which is a characteristic unique to our tool. The developed tool has certain strengths. Firstly, it is brief and simple and may be utilized in a resourcelimited setting. Secondly, it will help assess various forms of WPV, associated risk factors, and their impact. Lastly, the result of the developed tool will give government officials and healthcare practitioners in-depth knowledge regarding WPV. It will also help in devising various mitigation strategies to reduce WPV. However, there are three limitations: the semi-quantitative nature of the study, the lack of assessment of the predictive validity, and the lack of confirmatory factor analysis, which could alter the number of significant items in a construct and the total number of factors in the questionnaire. A credible and validated tool for obtaining information about workplace violence in the health sector from numerous geographic regions of the world has been established. The study is specifically looking into variables that may lead to violence and its impact, which would assist policymakers in curating various mitigation strategies to protect the victims of WPV.
