Abstract
Engagement and retention of suicide attempters in clinical research: Challenges and solutions
Gibbons, C.J., Stirman, S.W., Brown, G.K., & Beck, A.T.
Background
High attrition rates in longitudinal research can limit study generalizability, threaten internal validity, and decrease statistical power. Research has demonstrated that there can be significant differences between participants who complete a research study and those who drop out prematurely, and that treatment outcomes may be dependent on retention in a treatment protocol.
Aims
The current paper describes the challenges encountered when implementing a randomized controlled trial of cognitive therapy for the prevention of suicide attempts and the solutions developed to overcome these problems.
Methods
Problems unique to suicide attempters are discussed, and strategies successfully implemented to boost retention rates are provided.
Results
The methods implemented appeared to increase retention rates in the randomized controlled trial.
Conclusions
Many steps can be taken to work with this difficult population, and researchers are encouraged to be as involved and flexible with participants as possible.
