You Never Get a Second Chance to Make a First Impression: Effects of Visual Complexity and Cognitive Load on User Experience and Intention to Use Internet-Delivered Interventions
Rik Crutzen*

Background: High rates of attrition (i.e., drop-out) are characteristic of the Internet, especially in Internet-delivered interventions targeting health risk behaviours related to chronic diseases (e.g., a sedentary lifestyle, high fat intake and cigarette smoking). This touches upon the critical issue in Internet-delivered interventions: how can behaviour change ever be achieved if people do not or hardly use the actual intervention? Objective: To assess the effects of visual complexity a...

Using Google Analytics as a Process Evaluation Method for Internet-delivered Interventions: a Commendable Example on Sexual Health
Rik Crutzen*

Background Process evaluation aims to disentangle the factors that ensure successful intervention outcomes and attempts to document the steps involved in achieving successful implementation of an intervention.

This study focuses on a quantitative method that can be used during process evaluation of Internet-delivered intervent...

More recently, video messages are used to decrease high attrition rates: the major drawback of web-based interventions. Adolescents in particular are easily bored and prematurely quit these interve...
