Lotteries are any form of assigning an award where there is an element of randomness or chance.
One example is a prize-linked savings account (PLSAs). One of the earliest of these was the Million a Month Account (MAMA) in South Africa, where First National Bank offered account-holders with qualifying deposits a chance to win up to one million rand each month (along with other smaller prizes given out at random).
Lotteries may be used with non-financial rewards as well, e.g. offering tickets to a sold-out play or sporting event for employees reaching certain performance benchmarks.
Cognitive behavioral therapy (CBT) is a therapuetic approach to improving mental and behavioral health. The core philosophy is that behavior can be modified by noticing and correcting patterns in thought that influence the behavior. Modern CBT is typically associated with Albert Ellis and Alan Beck.
The structured and rules-based nature of CBT have made it a popular candidate for digital interventions and application by lightly-trained or even untrained practitioners.
ACT is a therapeutic approach originalled developed by Steven Hayes. It borrows from previous concepts like cognitive behavioral therapy and Morita therapy.
The principles of ACT are fairly systematic and lend themselves well to program design, finding empirical support in adaptations like 2morrow's smoking cessation and pain management interventions.
Motivational interviewing (MI) is a therapeutic approach that aims to influence behavior by eliciting goals, motivation, insights, and specific behavioral plans through structured dialog. It's largely associated with William Miller and Stephen Rollnick, and bears some relation to the Socratic method (as does the original cognitive therapy approach). While originally developed as part of a treatment for substance abuse, the method has been generalized and found empirical support in assisting behavior change in diet, exercise, and other areas.
Goal setting simply refers to a person choosing a specific result to aim at achieving. This might include an outcome (e.g. a goal weight) or a behavior (e.g. exercise 90 minutes 3 times a week).
Social benchmarking refers to comparing a person's behavior, trends, or status to others. Often, merely providing data on others can change behavior by leveraging social norms.
For example, letters comparing homeowners' use of electricity with peers were found to significantly reduce the amount of energy used by high-consumption households compared to non-comparison messages.
Peer mentoring refers to having individuals with a certain lived experience guide or train others facing similar ones. It is typically considered in contrast to expert coaching, formal teaching, or management guided by a clinician or doctor.
Compare, for example, a weight loss program delivered by a registered dietician vs. group sessions led by program 'graduates' like WW (formerly Weight Watchers). Note that these two approaches are not mutually exclusive.
