This letter provides an overview of a strategic argument of sustainability of treatment effects at follow-up. The argument that some psychotherapy orientations produced more sustainable outcomes at follow-up than others contributed to the split of the psychotherapy community into different camps. The sleeper effect as a lasting theoretical claim has survived over the past 100 years. The sleeper effect might be thought of as a strategic effect in the sense that the dominant and most powerful orientations in this time are 'pulled' to claim sustainability of their own approach; maybe in the hope of further decades of data collection to get an empirical proof of the claims.
