C4™ leads to higher attainment of health behavior goals and maintenance of health behaviors for longer periods.

The most important impediments to individuals achieving their health goal are factors related to the healthcare environment and other social and structural barriers. The demands and complexities of health and social service work can also affect motivation of agency staff.

C4™ moves beyond focus on the client as the sole target for health behavior change, towards engaging staff in re-creating their environments into ones that facilitate healthy behavior change and positive psychological well-being for their clients. It is an evidence-based approach supported through rigorous research on the effect of autonomy support on health behavior outcomes. It is culturally responsive, theoretically grounded and designed to support clients across the continuum of health care—from prevention through treatment.

The C4™ approach will help your staff support growth, motivation and connections that clients need to address social drivers of health.
