Effectiveness of aversion therapy for procrastination Pavlok is a product which is essentially a shock bracelet for Aversion Therapy. It markets itself as an intervention for a range of habits, including procrastination and nail-biting.

Is there any evidence that giving yourself a shock, when you catch yourself procrastinating or when someone else catches you procrastinating, will give you an aversion to the activities used for procrastination? Is it possible the person who receives the feedback would just find new activities?
From a 2014 review article on procrastination that doesn't mention aversive therapy at all, but has this to say about treatment(s) of procrastination in general:


  Even though procrastination can contribute to many adversities among those afflicted, research concerning treatment interventions is currently scarce. (Pychyl &amp; Flett, 2012) In terms of clinical trials investigating different
  treatment interventions, there is insufficient knowledge regarding their usefulness (Rozental &amp; Carlbring,
  2013). The research also lacks validated outcome measures, randomization, and long-term follow-ups, complicating
  the results. Treatment interventions stemming from cognitive behavior therapy (CBT) are often considered
  suitable for addressing problems of procrastination—interventions such as stimulus cues, time management,
  goal-setting techniques, learned industriousness, automaticity, stimulus control, modeling, performance
  accomplishments, implementation intentions, success spirals, and fusing (Steel, 2007)—but the evidence for
  their efficacy is still unclear (Pychyl &amp; Flett, 2012).
