Users’ Perceptions on a Persuasive Information System-Based Intervention for Child Healthcare: A Trial Study

Objective: This study aimed to examine users’ perception on a persuasive information system-based intervention for child healthcare through a research model that was developed using five pre-defined constructs. Methods: The study was carried out at Blinded, Oman in June 2017. Using five pre-defined constructs, a research model was developed. The constructs were used as latent variables to examine their likely impact on users’ perceptions and intentions to use a persuasive intervention for child healthcare. A structured questionnaire was validated and distributed among 150 participants to access their perceptions. Factor loadings and calculated variances were used to ensure validity and reliability of the research model. In addition, Cronbach’s Alpha was employed to measure the internal consistency and reliability. Results: Factor loadings and calculated variances for each item (per construct) were greater than 0.700 and 0.500 respectively. The Average Variance Extracted (AVE) values were above 0.635. The discriminant validity of all the correlations was below the desirable HTMT value of 0.90. Analyses of path coefficients and outer loadings indicate that Perceived Usefulness (p<0.001), Content of Intervention (p<0.050), Perceived Credibility (p<0.050) and Perceived Usefulness (p<0.050) can have a significant influence on Intention to Use the Intervention. Conclusions: The findings support the studied research model and indicate that users perceive an intervention to be persuasive given that it credible and its content is meaningful. When users perceive an intervention as being credible and useful, it develops their intention to actually use it in real life.
