The reform movement demonstrated that the environment can cause mental illness.

The belief that the environment can cause mental illness is supported by various research findings and theories in psychology and psychiatry. The reform movement was significant in addressing the treatment of individuals with mental illnesses, highlighting how external factors, such as living conditions, social support, and access to resources, can impact mental health.

Under this movement, there was a push for improved treatment conditions, recognizing that a positive environment could lead to better outcomes for individuals with mental health issues. This perspective emphasizes the importance of both environmental influences and individual circumstances in understanding mental health.

Choosing false disregards the substantial evidence and historical context that recognizes environmental impact as a crucial factor in mental health. The reform movement itself was fundamentally about acknowledging and improving these external conditions, suggesting that environments have a role in either exacerbating or alleviating mental health challenges.
