Final answer:
The deinstitutionalization movement that began in the 1960s was indeed one of the first building blocks of inclusion.
Step-by-step explanation:
The statement that deinstitutionalization movement that began in the 1960s was one of the first building blocks of inclusion is True.
Deinstitutionalization refers to the process of closing down large, state-run psychiatric hospitals and transitioning individuals with mental illness into community-based care. This movement aimed to integrate individuals with mental illness into society and provide them with community-based support systems rather than isolating them in institutional settings. This shift towards inclusion and community support was a significant step towards destigmatizing mental illness and promoting inclusion.
