A user-centred approach to developing bWell, a mobile app for arm and shoulder exercises after breast cancer treatment.

Purpose: The study aim was to develop a mobile application (app) supported by user preferences to optimise self-management of arm and shoulder exercises for upper-limb dysfunction (ULD) after breast cancer treatment.

Methods: Focus groups with breast cancer patients were held to identify user needs and requirements. Behaviour change techniques were explored by researchers and discussed during the focus groups.

Using qualitative methods within a mixed-methods approach to developing and evaluating interventions to address harmful alcohol use among young people.

Objective: This article illustrates how qualitative methods can be used in the development and evaluation of behavior change interventions. Although many campaigns advise young people to drink responsibly, few clarify how to convert this general advice into specific behavioral strategies. Resilience-based approaches argue that treating young non-drinkers and moderate drinkers as "experts" in responsible alcohol use may facilitate co-creation of acceptable interventions that focus on how to change behavior.

Validation of an iPad visual analogue rating system for assessing appetite and satiety.

The study aimed to validate appetite ratings made on a new electronic device, the Apple iPad Mini, against an existing but now obsolete electronic device (Hewlett Packard iPAQ). Healthy volunteers (9 men and 9 women) rated their appetite before and 0, 30, 60, 90 and 120 minutes after consuming both a low energy (LE: 77 kcal) and high energy (HE: 274 kcal) beverage at breakfast on 2 non-consecutive days in counter-balanced order. Rated hunger, desire to eat and how much participants could consume was significantly lower after HE than LE on both devices, although there was better overall differentiation between HE and LE for ratings on iPad.
