Which of the following is NOT a guideline for a successful LOUD Crowd program?

The correct answer highlights that allowing anyone with speech difficulties to join is not in line with the guidelines for a successful LOUD Crowd program. The LOUD Crowd program is specifically designed for individuals diagnosed with Parkinson's disease and related disorders who may experience speech difficulties due to their condition. The focus on this specific population ensures that the program effectively addresses the unique challenges faced by these individuals.

Involving only patients with Parkinson's-related disorders ensures that the exercises, goals, and community aspects of the program are tailored to their needs. Other options, such as completing all six SPEAK OUT! components during each session or requiring participants to have completed SPEAK OUT!, maintain the structure and effectiveness of the program by ensuring consistency and a shared experience among participants, which are critical for achieving the desired outcomes in speech improvement and communication skills.
