Behavior change and behavior design models

Tactics that change behavior

Acceptance and Commitment Therapy (ACT)
Acceptance and Commitment Therapy (ACT)

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.

Behavior Substitution
Behavior Substitution

Behavior substitution refers to attempting to eliminate a problematic behavior by replacing it with another one.

Often, the substituted behaviors are intended to have similar sensory qualities (e.g. drink flavored sparkling water instead of soda). The goal is typically to disassociate the original behavior from its cue, enabling the more positive behavior to be triggered automatically.

Social Norms
Social Norms

Social norms are shared expectations on how people within a certain group will or should behave. They are often considered as unwritten rules that govern behavior and tend to be very influential.

Influencing behavior using social norms can take a variety of forms. For example, some studies aim to correct misunderstandings around descriptive norms (what people in a group actually do). One trial involving the UK Behavioural Insights Team increased tax compliance by emphasizing that the vast majority of people pay their taxes on time, which influenced non-compliers to become more like the majority. People generally do not like to deviate from the norm, which may explain the success of this tactic.

Other approaches involve attempting to change social norms or create new social norms, which is substantially harder. One prominent example was the promotion of the ""designated driver"" (DDs) in the US during a period of high automobile fatalities. Public health officials influenced Hollywood producers to include the designated driver in film and television scenes, which caused viewers to: 1) likely believe the use of DDs was much more common than it actually was, and 2) likely consider using a DD was what they ""should"" do (i.e. the injunctive norm). Following the public health campaign, awareness and compliance with the DD protocol rose substantially, and auto fatalities dropped precipitously.

Coaching or Counselling
Coaching or Counselling

Coaching or counselling here refers to having a trained person provide guidance to someone attempting a behavior. Many mental health and lifestyle programs utilize coaching in various forms, including phone calls, video chat, text messaging, or in-person sessions. Some programs have replaced some or all of these traditionally human-delivered touchpoints with AI or rules-based interactions.

Gamification
Gamification

Gamification refers to leveraging mechanics and other experiential elements typically associated with games in non-game contexts.

These can be fairly subtle (e.g. a progress bar for filing out a health risk questionnaire), moderate (e.g. achievements given for reaching personal finance goals, contests for steps walked as a team in a workplace wellness competition), or extreme (e.g. an augmented reality experience to treat chronic pain). At the extreme end, the distinction between a gamified experience and an actual game may be considered almost academic.

Group Incentives
Group Incentives

Group incentives refer to structure where an individual's likelihood or size of reward is influenced by others. The intention is to leverage positive peer pressure by causing compliant participants to influence less compliant participants to improve their behavior.

For example, sales teams may be offered a bonus based on an office's collective revenue generation or provided all individuals meet a baseline level of performance. Similarly a multi-site franchise may offer an incentive for whichever location improves their performance the most over the prior month.

Micro-Incentives
Micro-Incentives

Micro-incentives refers to small rewards, typically frequent and cash-based, given out on a per-behavior basis.

A prominent example is Wellth, a program for people with chronic illness delivered via app. Some participants are given around $2 each time they take a medication or measure their blood pressure and submit a photo.

In related studies, e.g. Petry et al. (2015), participants' compliance with these behaviors was significantly higher than those who did not receive the incentives, and the behaviors persisted several months after incentives were removed.

Micro-incentives can be layered with other reward approaches such as lotteries and non-financial incentives.
