Developing an Evaluation System for Quality of Health Educational Short Videos on Social Media (LassVQ): Nominal Group Technique and Analytic Hierarchy Process
ABSTRACT
Background:
With the increasing use of social media platforms for health communication, the quality of health popularization videos has become a key concern. However, no standardized framework exists to evaluate the quality of health videos on social media, highlighting the need for a comprehensive evaluation system.
Objective:
The aim of this study is to identify the evaluation indicators, map them into various topics of quality of health popularization videos on social media, and finally prioritize the major indicators.
Methods:
The indicators obtained from the literature review were provided to the nominal group reference Lasswell’s 5W communication model, and the process of nominal group technique (NGT) was carried out to reach a consensus of evaluation system. The indicators were then ranked based on their significance using the analytic hierarchy process (AHP).
Results:
The primary indicators include communicator, communication content, communication channel, communication effect, along with 13 secondary indicators. Among these, communication content was found to be the most influential indicator and weighted 45.68%. Credibility, scientific, availability, and social attention were the most influential quality evaluation indicators with a priority of 56.67, 24.26, 74.62, and 39.89% in their own categories, respectively. The content validity of all the evaluation indicators was excellent.
Conclusions:
The evaluation system for quality of health popularization videos on social media (Q-HPVSM) was developed and its validity were excellent. The proposed evaluation system can be used in conjunction with qualitative methods, to gain a holistic perspective concerning the multidimensional quality of health popularization videos on social media. Clinical Trial: none
