Convergent Validity for the Music in Everyday Life Assessment Tool

Area of Science:

• Music therapy research
• Autism spectrum disorder assessments
• Psychometric validation

Background:

• Further research is needed on music therapy's impact on daily life for individuals with autism.
• The psychometric validity of music therapy assessments requires robust evaluation.

Purpose of the Study:

• To explore the convergent validity of the Music in Everyday Life (MEL) assessment.
• To examine the relationship between MEL subscales (MEL-JAM, MEL-RAM) and established autism measures (ADOS, SRS).

Main Methods:

• Convergent validity was assessed using Spearman Rank Correlation.
• Data were collected from 106 participants across four countries.
• Relationships between MEL, Autism Diagnostic Observation Schedule (ADOS), and Social Responsiveness Scale (SRS) scores were analyzed.

Main Results:

• A low to moderate positive correlation was found between MEL subscales and Autism Diagnostic Observation Schedule (ADOS) scores.
• No significant correlations were observed between MEL subscales and Social Responsiveness Scale (SRS) scores.
• The clinical meaningfulness of correlations between MEL and ADOS requires further investigation due to assessment heterogeneity.

Conclusions:

• The convergent validity of the Music in Everyday Life (MEL) assessment requires further investigation.
• Future research should explore other validity measures, such as factor analysis, for the MEL assessment.
• The relevance of symptom severity diagnostic assessments in validating music therapy tools needs consideration.
