Diabetes Text-Message Self-Management Support Program (SMS4BG): A Pilot Study
JMIR mHealth and uHealth 2015; 3(1):e32
Our team has developed a self-management support programme delivered by text messages for those with poorly controlled diabetes. The programme is based on behaviour change theory and techniques, and aims to improve motivation and self-efficacy for better control. This pilot study showed a dramatic reduction in HbA1c levels in those who provided before/after results, and overwhelmingly positive feedback from participants. A large national RCT is now underway.

Dr Whittaker spent some time in the U.S. where she led this review of text4baby – a national text message health information programme for pregnant women. This review examined the first >100,000 enrollees, and described the journey of establishing possibly the largest national text messaging health programme.

Based on their experience, our team has described a process for the development of mHealth and text messaging-based health interventions. This stresses the importance of the involvement of the target audience from the start, a theoretical basis, and consideration of how the intervention will be rolled out and implemented.

MEMO: living in a positive space. Development and post-program satisfaction in a randomized controlled trial of a mobile phone intervention
JMIR 2012: 14(1); e13
Our team worked with Prof Merry’s team to develop a multimedia depression prevention programme for all adolescents. The intervention used video, cartoons and key messages – all delivered to teens via text messages – based on cognitive behavioural therapy. A large randomized trial was conducted across 15 high schools in Auckland, with the results still to be published.
A randomised controlled trial of mobile (cell) phone text messaging smoking cessation support: txt2stopLancet 2011; 378(9785):49-55.
Our team worked with the London School of Hygiene and Tropical Medicine to deliver our world first text messaging smoking cessation intervention to 5800 trial participants in the UK. The team at LSHTM conducted a high quality RCT with very high rates of follow-up and verification of quitting. This confirmed the doubling of quit rates with the intervention compared with the control group that we had previously seen in NZ. This paper won the RCGP Paper of the Year award.

Smoking cessation using mobile phone text messaging is as effective in Maori as non-Maori
New Zealand Medical Journal 2005;118; 1216.
This is one of the original papers on STOMP – NIHI’s seminal text message smoking cessation intervention developed by Prof Rogers (previous Director of NIHI) as the first ever trial published on a health intervention delivered solely by text message. This paper demonstrated that STOMP was as effective for Maori participants as it was for non-Maori participants in helping them to stop smoking.
