Behavior change and behavior design models

Tactics that change behavior

Social Support
Social Support

Social support refers to the perception or reality that other people will provide assistance in a given context. It is a key component of several behavior models and plays an important role in mediating behavior change.

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.

Skill Coaching
Skill Coaching

Skill coaching simply refers to guiding a person to acquire a new behavior or set of behaviors, often by scaling the information and challenge level with their growing ability.

Examples of this might include teaching someone to cook healthy foods or training them in various self-regulation techniques from cognitive behavioral therapy. This coaching may be done by an individual or automated through digital experiences.

Reminders, Cues, or Prompts
Reminders, Cues, or Prompts

Reminders, cues, and prompts are simply methods to cause someone to perform a behavior by calling their attention to it with a timely message. People have limited attention and memory, so these types of influences can be very effective when done skillfully.

The cue need not consist of written or spoken language; for example, it could be a certain melody, symbol, or pattern of lights on a connected home device. It might also be a bracelet or pattern of vibrations from a wearable device. Provided the cue or prompt is associated with the behavior, almost any sensory stimuli that is reliably perceived and interpreted may be used. That said, verbal reminders can be effective since they may be personalized with additional semantic information related to the person's context or leverage other effects (e.g. identity priming or framing effects).

Self-Monitoring or Tracking
Self-Monitoring or Tracking

Self-monitoring or tracking simply refers to a person measuring their behavior, experiences, cognition, or other data points over time.

Often, merely tracking a behavior can influence the likelihood or frequency with which a person performs the behavior or related ones. For example, many pedometer studies increase walking activity merely by improving awareness, and many interventions that merely consist of rewarding someone for weighing themselves result in weight loss. Similarly, when cognitive behavioral therapy patients track which cues or environments are associated with undesired behaviors or thoughts, they may begin to avoid them.

Unfortunately, people often find tracking behaviors tedious and lose interest after a short period, so behavior designers should seek to reduce the burden of self-monitoring by collecting information automatically or doing so in a low-effort way.

Lotteries
Lotteries

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.

Checklists
Checklists

Checklists are an age-old tactic for remembering to do certain tasks. Checklists are sometimes used to measure behaviors that should take place with a certain frequency, e.g. every day or X times per week, and other times, to ensure certain steps are followed every time a person does a complex behavior.

For behavior designers, the challenges of checklists often entail choosing the right behaviors, breaking them down to the correct level of granularity for a given population, and serving them up in the proper context or sometimes with personalization. They are likely underutilized and consistently improve the performance of even experts, like pilots and surgeons.

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.
