Treatment is delivered via individual therapy, group therapy, day treatment programs, and remote video sessions through the NPI Online platform (launched 2022), with specialized programs for youth ages 16-23 and pregnant/postpartum women.

The organization employs approximately 200 specialized clinicians including psychiatrists, clinical psychologists, psychotherapists, GZ-psychologists, and social psychiatric nurses, many of whom serve as trainers and supervisors in professional education programs. NPI holds TOPGGz certification (since 2016, recertified 2020 and 2024) and HKZ quality certification, indicating highly specialized care combined with scientific research and knowledge dissemination.

Clients cannot self-refer; they must be referred by general practitioners, medical specialists, or other recognized healthcare professionals through the Central Login of Arkin (CAA). The organization also provides consultation services to referring practitioners, second opinions for complex cases, and family support programs in partnership with Arkin's Prevention Department. NPI is not independently funded through venture capital or public investment and operates entirely within the Dutch healthcare funding system.
