What is the purpose of the Client Oriented Scale of Improvement (COSI)?

  1. To provide post-fitting assessments

  2. To evaluate the safety of hearing aids

  3. To provide pre-fitting assessment of hearing loss

  4. To analyze the audio frequency range

The correct answer is: To provide pre-fitting assessment of hearing loss

The Client Oriented Scale of Improvement (COSI) is primarily designed to assess the specific needs and expectations of individuals with hearing difficulties before they receive any interventions, such as hearing aids. By focusing on individual goals, COSI gathers information on how clients perceive their hearing challenges and what they wish to improve. This pre-fitting assessment allows audiologists to tailor their approach and recommendations based on the unique circumstances and desires of each client. In contrast, the other options do not accurately capture the essence of COSI. Post-fitting assessments are typically aimed at measuring the effectiveness of a fitting, while evaluating safety concerns of hearing aids falls under different types of assessments that are not the core purpose of COSI. Analyzing the audio frequency range is more technical and related to the measurement of sound, rather than understanding client-specific concerns and improvements in hearing quality. Therefore, the distinctive aim of COSI as a pre-fitting assessment highlights its role in client-centered care in audiology.
