Given the widespread adoption and technical possibilities of mobile technology, mobile health apps could be potentially effective tools to intervene in people’s daily routines and stimulate physical activity. Self-determination theory and the motivational technology model both suggest that mobile technology can promote health behaviour change by allowing users to customize their online experience when using mobile health apps. However, we know very little about why and for whom customization is most effective. Using a between-subjects experimental design, we tested the effects of customization in mobile health apps among a convenience sample (N = 203). We assessed the effects of customization on perceived active control over mobile health apps, autonomous motivation to use mobile health apps, and intention to engage in physical activity, and tested the moderating role of need for autonomy. Structural equation modelling showed that customization in mobile health apps does not increase perceived active control, autonomous motivation, or the intention to engage in physical activity. However, an interaction effect between customization and need for autonomy showed that customization in mobile health apps leads to higher intentions to engage in physical activity for those with a greater need for autonomy, but not for those with a lesser need for autonomy. The implications for theory and practice are discussed.

Title: OCA-IV ‘How to effectively tailor website information to older colorectal cancer patients’ mode preferences: A Randomised Controlled Trial’
This project focuses on how online information should be presented to older cancer patients. In a randomised controlled trial, we investigate the effects of exposure to a website that is tailored to colorectal cancer patients’ mode preferences (offering choices between text only, text with illustrations, video or a combination of these modes) as compared to exposure to a websites presenting the information in a standardised, fixed manner. We particularly focus on differences between older (≥ 65 years) and younger (< 65 years) patients, taking into account both age and age-related factors. The primary outcomes are recall of information and distress before and after the consultations with health professionals. Secondary outcomes are communication during the consultations, patients’ evaluation of the communication, and perceived quality of the decision making process. Ultimately, we aim to establish theory- and evidence-based guidance for optimal information provision to older cancer patients.

Nadine Bol and Hao Nguyen both won the Philip C. Palm Green Top Student Paper Award at the Kentucky Conference on Health Communication 2016. They received the exact same reviewer score, and the scientific advisory board could not make a final decision between the two papers. The committee therefore decided to award them both with the award. Congratulations to both Nadine and Hao!
