Randomized Controlled Trial Comparative StudyOptimizing engagement with Internet-based health behaviour change interventions: comparison of self-assessment with and without tailored feedback using a mixed methods approach.
Internet-based health behaviour interventions have variable effects on health-related outcomes. Effectiveness may be improved by optimizing the design of interventions. This study examined the specific effect on engagement of providing two different design features - tailoring and self-assessment. ⋯ The acceptability of self-assessment or monitoring components may be optimized by also providing tailored feedback. Without tailored feedback, these components do not appear to be any more engaging than generic information provision. Statement of contribution What is already known on this subject? Digital interventions can be effective for improving a range of health outcomes and behaviours. There is huge variation in the success of different interventions using different combinations of design features. What does this study add? This study used a systematic experimental design to identify the effect on engagement of providing interactive intervention design features alone and in combination. Intervention engagement was better when self-assessment was provided in conjunction with tailored feedback.

Randomized Controlled TrialA pilot randomized controlled trial to increase smoking cessation by maintaining National Health Service Stop Smoking Service attendance.
The National Health Service (NHS) Stop Smoking Service (SSS) is an extremely cost-effective method of enabling smoking cessation. However, the SSS is only used by a minority of smokers. Developing interventions to maintain service attendance may help to increase the number of quitters. This study pilots an intervention aimed at maintaining attendance by (1) increasing motivation to attend through a booklet providing evidence of service effectiveness and (2) strengthening the link between motivation to attend and attendance through forming an implementation intention. ⋯ What is already known on this subject? The NHS Stop Smoking Service is an effective yet underused method of enabling smoking cessation. Low uptake levels may be due to smokers' misconception that the service will not improve their chances of quitting successfully. Improving smokers' perceptions of service efficacy may be valuable for maintaining service attendance, and subsequently improving smoking cessation levels in the United Kingdom. What does this study add? This pilot randomized controlled trial is the first to target service attendance rather than cessation levels. The results demonstrate that providing evidence of service efficacy in a simple icon array format can significantly improve service attendance.

Predicting quality of life 5 years after medical discharge for traumatic spinal cord injury.
This study tested an a priori contextual model of the mediating effects of participation on the predictive relationships of functional impairment, family satisfaction, and pain to quality of life (QoL) following traumatic spinal cord injury (SCI). ⋯ What is already known on this subject? Life satisfaction and self-rated health status are important aspects of quality of life following traumatic spinal cord injury. Functional impairment has been inconsistently predictive of these variables over time. Prospective research to date has not examined the mediating effects of participation in predicting quality of life. What does this study add? The results indicate that greater functional impairment and pain are prospectively predictive of lower participation. Greater participation, in turn, is prospectively predictive of greater quality of life. Participation appears to mediate the prospective influence of functional impairment, family satisfaction, and pain to quality of life.
