Introduction
In an era marked by unprecedented advancements in communication technology, the dissemination of health information has undergone a profound transformation.Information flows incessantly through an intricate web of media sources, rapidly influencing the way individuals perceive, interpret, and act upon health-related content.The omnipresence of these media outlets offers tremendous potential to empower individuals with knowledge and support informed healthcare decisions.However, this expansive and often unregulated media landscape has also given rise to a complex phenomenon: media accessibility and the pervasive presence of information asymmetry.
Media, in all its forms -be it television, online platforms, newspapers, or social media -wields unparalleled power in shaping public perception of health matters.Its role transcends mere information delivery; it Molds attitudes, constructs narratives, and sways decisions.The impact of media accessibility on healthcare consumers is undeniable, but its effects are far from uniform.As we delve into this multifaceted domain, it becomes increasingly apparent that not all individuals experience media influence in the same way, nor do they have equal access to health information.This nuanced interplay between accessibility, media influence, and information asymmetry forms the crux of our investigation.
The accessibility of health information via diverse media channels is accompanied by disparities that warrant our scrutiny.Health communication scholars have long recognized the unequal distribution of resources and information in society, leading to what is commonly referred to as information asymmetry.Information asymmetry occurs when one party in a transaction (in this context, media outlets and healthcare consumers) possesses more or better information than the other, giving rise to potential imbalances in knowledge, power, and decision-making.While the existence of information asymmetry is well-documented, an in-depth understanding of how it manifests within the realm of health communication, particularly in the context of evolving media landscapes, remains a significant gap in the literature.To address this gap, our study embarks on a comprehensive exploration of media accessibility and information asymmetry in the context of health communication.We aim to unravel the intricate relationships between media consumption, the differential availability of health information, and the consequential implications for healthcare decision-making and outcomes.
The Media Influence on Health Information Perception and Behavior Scale (MIHIPB-S) is a research tool designed to assess individuals' perceptions of health information from different media sources and how this information influences their health-related decisions and behaviors.It aims to understand the role of media in shaping health knowledge, trust in healthcare providers, information evaluation, emotional responses, and information source diversity.

Materials And Methods
This research employs a comprehensive mixed-methods approach for the development and validation of the MIHIPB-S, focusing on content validity assessment using the CVI method.The study encompasses multiple phases, including item generation, expert panel formation, content validity assessment, and pilot testing.The initial phase of questionnaire development involved an extensive review of relevant literature in health communication, media studies, and related fields (Brown, 2018; Smith & Jones, 2020).This literature review aimed to identify key constructs, themes, and dimensions relevant to media influence on health information perception and behavior (Garcia & Martinez, 2019).

Item Pool Creation
In the item pool creation phase, a meticulous and comprehensive literature review was conducted across multiple disciplines, including health communication, media studies, psychology, and public health (Brown, 2018;Garcia & Martinez, 2019;Wilson et al., 2021).The aim was to identify and understand the complex landscape of media influence on individuals' perceptions and behaviors related to health information.

Identifying Key Constructs and Dimensions
During the literature review, key constructs, themes, and dimensions emerged that were relevant to the study's overarching goal of assessing media influence on health information perception and behavior.These included: Media Channels: Various media channels, such as television, online platforms, social media, print media, and radio, were identified as sources of health information (Johnson, 2017).

Trust and Credibility:
The importance of trust in media sources and the credibility of health information presented by these sources were recurring themes (Garcia & Smith, 2017).

Information Accessibility:
The ease or difficulty of accessing relevant health information through media channels was recognized as a crucial factor (Smith & Jones, 2020).

Impact on Decision-Making:
The extent to which media exposure influenced individuals' healthrelated decision-making processes and behaviors was a central focus (Brown & White, 2021).https://jazindia.comAvailable online at: -1407 -Information Evaluation: The ability of individuals to critically evaluate the accuracy and reliability of health information in the media was highlighted (Miller & Davis, 2019).

Iterative Process
The item pool creation process was iterative, involving constant refinement and adjustment based on the literature review findings.It was essential to ensure that the items accurately represented the relevant constructs and dimensions while maintaining clarity and relevance to the target population.The item pool creation process was a meticulous and data-driven endeavor that leveraged insights from a comprehensive literature review to generate a preliminary set of questionnaire items.These items were designed to capture the multifaceted nature of media influence on health information perception and behavior, forming the foundation of the MIHIPB-S questionnaire.This table provides a structured summary of the expert panel formation process, including selection criteria, composition, informed consent, expertise diversity, and the emphasis on confidentiality and impartiality.

Expert Ratings
In the content validity assessment phase, the expert panel played a pivotal role in evaluating each item within the preliminary item pool for its relevance to the construct under study, which was "Media Influence on Health Information Perception and Behavior" (Chen et al., 2020).

Independence and Objectivity
The expert panel members, who were carefully selected based on their qualifications and expertise, carried out independent evaluations of each questionnaire item (Brown & White, 2021).This independence ensured that each expert's assessment was based on their individual professional judgment and expertise.

Use of a 4-Point Likert Scale
To standardize the content validity assessment process, a 4-point Likert scale was utilized (Wilson & Davis, 2020).Experts assigned a score to each item based on their judgment of its relevance to the construct.The Likert scale ranged from: 1 = Not relevant: Signifying that the item was not deemed relevant to the construct of "Media Influence on Health Information Perception and Behavior." 2 = Somewhat relevant: Indicating that the item had some relevance but was not strongly aligned with the construct.Available online at: https://jazindia.com-1408 -3 = Quite relevant: Suggesting that the item was relevant to a considerable extent concerning the construct.4 = Highly relevant: Signifying that the item was highly relevant and directly aligned with the construct.

Assessing Relevance to the Construct
During this assessment, experts considered several factors when assigning scores: Alignment with Research Focus: Experts evaluated whether each item pertained to the central theme of media influence on health information perception and behavior, as defined in the research objectives (Garcia & Smith, 2017).
Clarity and Precision: Items were assessed for clarity and precision to ensure that they effectively captured the intended concepts related to media influence (Johnson & Smith, 2018).
Consistency with Literature: Experts cross-referenced items with relevant literature to ensure they were consistent with established theories and empirical findings in the field (Miller & Davis, 2019).
Comprehensiveness: The experts considered whether the items collectively covered a broad spectrum of aspects related to media influence on health information, avoiding redundancy or omission of critical dimensions (Davis & Robinson, 2019).

Ensuring Rigor and Objectivity
The use of a Likert scale and the requirement for experts to provide numerical ratings ensured objectivity in the assessment process.The process aimed to identify items that achieved consensus among the experts as being relevant to the construct while identifying those that required further consideration or revision (Brown & Johnson, 2018).
The expert ratings phase was crucial in determining the content validity of the MIHIPB-S questionnaire, as it provided a systematic and evidence-based approach to assess the relevance of each item to the construct of interest.Items with higher ratings were more likely to be retained in the final questionnaire, while those with lower ratings may have been considered for modification or removal.

Scale Purpose:
the MIHIPB-S serves as a versatile tool for researchers, academics, and professionals in health communication and media studies.Its purpose is to facilitate in-depth investigations into the complex relationship between media influence and health information perception and behavior, while also aiding in the assessment of content validity in measurement instruments within this domain.

Scale Application:
Researchers, academics, and professionals in health communication, media studies, and related fields can utilize the MIHIPB-S to conduct rigorous investigations into the multifaceted relationship between media exposure and individuals' health-related decision-making processes.The scale allows for indepth exploration and analysis of various dimensions of media influence on health information perception and behavior.
The MIHIPB-S is a testament to the commitment of its authors, Choudhary and Dubey, in advancing the understanding of how media shapes individuals' health-related attitudes and actions.It represents a valuable addition to the research toolkit for scholars interested in this critical and evolving area of study.
The Media Influence Scale (MIHIPB-S) uses a 4-point Likert scale for responses, with the following marking scheme: 1 = Not at all: This response indicates that the participant does not perceive the stated influence or behavior to any significant degree.
2 = Slightly: This response suggests a minimal or slight perception of the stated influence or behavior but not to a substantial extent.

In this table:
Expert in Agreement: This column shows the number of experts (out of 9) who agreed on the relevance of each item in the questionnaire.
I-CVI: The Item-Level Content Validity Index (I-CVI) is calculated as the proportion of experts who rated each item as relevant (1).The I-CVI values for all items range from 0.7 to 1.The items with an I-CVI of 0.9 or higher are typically considered acceptable.

UA (Universal Agreement):
The UA score is assigned '1' when an item achieved 100% agreement among all experts (i.e., all experts rated the item as relevant).In this case, none of the items achieved universal agreement (all have a UA of 0).
Proportion Relevance: This row at the bottom of the table represents the proportion of experts who rated each item as relevant.For example, for Q1, all 9 experts rated it as relevant (1), resulting in a proportion relevance of 1.Similarly, for Q2, 8 out of 9 experts rated it as relevant, resulting in a proportion relevance of 0.7.
Overall, the I-CVI values suggest that most of the items in the questionnaire are considered relevant by the majority of the experts, with I-CVI values of 0.9 or higher.However, none of the items achieved universal agreement (UA = 0), indicating that there was not 100% agreement among all experts on any item.
Please note that I-CVI values of 0.9 or higher are generally considered acceptable for content validity.
Depending on your research objectives and standards, you may decide to retain, revise, or remove items based on these values.

Two Experts (Davis, 1992): When
(Lynn, 1986;Davis, 1992;Polit & Beck, 2006;Polit et al., 2007) they provide quantitative measures of the agreement among content experts regarding the relevance of items within a measurement instrument.They help researchers gauge the extent to which items are relevant to the construct under study and ensure the validity of the instrument for its intended purpose.These definitions and formulas are based on recommendations by Lynn, Davis, Polit & Beck, and Polit et al., providing a standardized and evidence-based approach to content validity assessment(Lynn, 1986;Davis, 1992;Polit & Beck, 2006;Polit et al., 2007).
content validity is assessed by only two experts, an acceptable CVI value is set at a minimum of 0.80.This implies that if two experts independently agree that an item is relevant to the construct, it must have a CVI of at least 0.80 to be considered acceptable.This cut-off reflects a moderate level of agreement among a small panel.2.Three to Five Experts (Polit & Beck, 2006; Polit et al., 2007):When three to five experts are involved in the content validity assessment, the CVI should ideally be 1.00, indicating perfect agreement among experts.This suggests that the item is unanimously considered relevant and is a crucial criterion for ensuring content validity.A CVI of 1.00 is expected due to the larger number of experts contributing their perspectives.maintaininghighagreementamongexperts when a moderate-sized panel is utilized.5.At Least Nine Experts (Lynn, 1986):In cases where there are at least nine experts, an acceptable CVI is set at a minimum of 0.78.While this threshold is slightly lower than others, it still indicates a substantial level of agreement among experts and supports the notion that a larger panel size can accommodate some degree of variability in ratings.Definitions and Formulas of Cvi IndicesTable 3: Definitions and Formulas of CVI Indices https://jazindia.comAvailable online at:
