Prepmate
PrEPmate is a multicomponent mHealth intervention grounded in the information, motivation, and behavioral (IMB) theory of behavior change and developed through user-centered design. It uses SMS and interactive online content to enhance PrEP adherence among YMSM. The SMS-based adherence support component includes weekly “check in” messages asking participants how PrEP is going, and daily pill-taking reminder messages sent at a customized time consisting of fun facts and trivia for the 2 weeks after initiating PrEP, with the option to continue reminders throughout the study.

TACTICS
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.

TACTICS
Implementation Intentions
Implementation intentions are specific details for when and how a behavior should or will be performed. These are often formulated as ""if-then"" rules, such as:- "if I crave something sweet, I'll have fruit instead of candy"- "if I am in the mood for a cigarette, I'll wait 5 minutes—then, if I still want it, I can have one"Other examples include studies where flu vaccination uptake was higher in groups of people nudged to make more specific plans (i.e. picking a specific time and date, along with a mode of transport to a specific clinic). The same general effect was observed with voting behaviors. These are a generally low-cost tool to slightly improve the gap between intention and performance of a behavior.

TACTICS
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).

TACTICS
Education or Information
Education refers to empowering a person with more knowledge or training than they had previously. While providing information alone is often a suboptimal way to drive meaningful behavior change or long-term interventions, the right message at the right time can be a powerful part of a behavior change strategy.
