Research On Patients' Perceived Value On Social Media And Its Relationship With Usage Intention

Objectives:Starting from the research situation of patients using social media to obtain health information services,we summarize relevant research results at home and abroad,then construct a perceived value measurement scale tested and modified under this situation by using a combination of theory and empirical research methods.On this basis,we further explore the specific relationship between perceived value and patients' willingness to use social media,and verify it through empirical research.Methods:First,we refer to the existing mature scale of perceived value to determine the dimensions of the perceived value in the context of this study,selectively absorb some items and contextualize,and at the same time increase related items as needed to form the scale of patients' perceived value on social media.Then the questionnaire is designed based on the scale and the questionnaire survey is conducted.Cronbach ? reliability test is performed on the scale through SPSS24.0,and exploratory factor analysis is carried out to test the validity,thereby completing the correction of the scale.Then,the relationship model between patients' perception value of social media and their willingness to use in the context of this research is constructed,and related hypotheses about relationship between the dimensions of perceived value and willingness to use are proposed.Then we conduct a questionnaire survey,use the constructed scale to investigate the current patient's perceived value of social media,and use AMOS21.0 to conduct structural equation model analysis and path significance test on the survey data to verify the constructed relationship model and research hypothesis.Results:(1)The initial scale of the patient's perceived value on social media includes 5 dimensions,a total of 19 measurement items.The data analysis results show that the overall reliability coefficient of the scale is 0.869,which indicates that the reliability is high;after the factor analysis,two items whose communalities do not meet the standard are deleted.Then the factor analysis is performed again after deleting the items,and the results show that the scale has good validity.The final revised scale includes 5 dimensions and a total of 17 measurement items.(2)A questionnaire survey was conducted on 398 patients who used social media to obtain health information services during medical treatment.The survey results showed that their overall perceived value on current social media was low,with an average value of 63.794.In terms of dimensions,the average value of experience value is the highest at 3.805;the average value of emotional value is the lowest at 0.705;the average values of the three dimensions of social value,emotional value and safety value are 3.771,3.734 and 3.737 respectively.(3)The data analysis results show that the constructed model of the relationship between the perceived value of patients on social media and the willingness to use has a good fit,and the path significance test results show that the five paths in the model are all significant,that is,the five hypotheses that the five dimensions of perceived value significantly affect the willingness of patients to use have been verified.Among them,the standardized path coefficient of the influence of information value on usage intention is the largest,which is 0.671,and this path shows a high level of significance;the standardized path coefficients of affective value and experience value that influence usage intention are 0.228 and 0.364 respectively,and both show very high significance;the standardized path coefficient of social value affecting usage intention is 0.134,and this path shows a high level of significance;the standardized path coefficient of safety value affecting usage intention is 0.128,and this path shows a high level of significance.Conclusions:(1)Patients' perceived value on social media includes five dimensions: information value,social value,emotional value,experience value and safety value.The scale after tested and revised has a total of 17 measurement items.And the scale has good reliability and validity,which can be used for actual measurement.(2)The survey results show that the current patient's overall perceived value on social media is low.It shows that the health information services provided by social media cannot fully meet the needs of patients.In the future,we should start from all dimensions of perceived value and focus on enhancing the perceived value of patients on social media.(3)The empirical results show that the constructed model of the relationship between the perceived value of patients on social media and the willingness to use has a good fit,and the five dimensions of perceived value(information value,social value,emotional value,experience value and safety value)all significantly positively affect patients' willingness to use social media.And the model has a strong explanation for usage intention.
