The Individual Music-Centered Assessment Profile for Neurodevelopmental Disorders (IMCAP-ND) is a method for observing, listening, and rating musical emotional responses, cognition and perception, preferences, perceptual efficiency, and self-regulation in individuals with neurodevelopmental disorders. Within musical-play, and a developmental and relationship-based framework, the IMCAP-ND focuses on how clients perceive, interpret, and create music with the therapist as the first step in formulating clinical goals and strategies for working with clients. The IMCAP-ND includes three easy to use rating scales that evaluate clients at various developmental levels and chronological ages from children to adults. In addition, it provides the therapist with musical procedures and protocols as well as guiding principles for facilitating the in-session assessment process. The IMCAP-ND clinical manual includes protocols, supportive intervention procedures, rating scales, intake forms, and an assessment/evaluation report template. The IMCAP-ND may be used: • to develop clinical goals and treatment plan • to musically guide the therapist in working with the client • to communicate information to parents and healthcare professionals • as pre- and posttest measures to evaluate client progress
