Packages of SBC interventions include community mobilization as well as programs that have multiple components (including IPC and mass media). Many SBC interventions are designed to include multiple approaches; as it's often hard to separate out the impact of each approach, the combined impact of these combinations is captured under packages.
SBC packages were found to be positively associated with all intermediate outcomes and are especially suited to improving communication between partners about family planning.
Many of the components include reaching large groups of individuals, so may be able to achieve higher scale than IPC alone.
Interpersonal communication (IPC) interventions include both individual and group efforts to exchange information and explore attitudes and norms.
IPC was found to be positively associated with all intermediate outcomes except communication with others (e.g., friends, family) about family planning. IPC is especially suited to improving attitudes on the benefits, safety and effectiveness of family planning, as well as improving intentions and self-efficacy of family planning.
Because these interventions are fairly intensive (requiring a trained individual to engage with other individuals or small groups) they may not be able to easily achieve the same level of scale as other SBC interventions.
Mass media interventions use multiple channels—including TV, radio, digital, and social media—to reach audiences with messages about healthy behaviors.
Mass media was found to be positively associated with all intermediate outcomes and is especially suited to increasing approval of family planning and communication with others (e.g., friends, family) about family planning.
By employing media channels, these interventions are able to achieve wide reach when scaled—for example, utilizing national radio stations to reach all those who regularly listen to radio.
