The Motivation Assessment Scale (MAS) reliably identifies factors maintaining self-injurious behavior in individuals with developmental disorders. This validated tool aids in understanding and managing challenging behaviors.

Area of Science:

  • Behavioral Psychology
  • Developmental Psychology
  • Clinical Psychology

Background:

  • Self-injurious behavior (SIB) is a significant challenge for individuals with autism and developmental disorders.
  • Identifying the maintaining variables of SIB is crucial for effective intervention.
  • Existing functional analyses can be time-consuming and resource-intensive.

Purpose of the Study:

  • To report reliability and validity data for the Motivation Assessment Scale (MAS).
  • To establish the MAS as a tool for identifying situational determinants of SIB.
  • To offer an alternative or adjunct to formal functional analyses.

Main Methods:

  • The study involved a reliability assessment with 50 teachers of individuals with developmental disabilities.

  • A validity study was conducted with 8 subjects, assessing MAS ratings against behavior in analogue situations.
  • The MAS is a 16-item questionnaire assessing situational factors of SIB.

    • Main Results:

    • High interrater and test-retest reliability were found for the MAS.
    • MAS ratings accurately predicted SIB in specific analogue situations (e.g., low attention, high demands, restricted access, unstructured settings).
    • The MAS demonstrated predictive validity for understanding SIB triggers.

    Conclusions:

    • The Motivation Assessment Scale (MAS) is a reliable and valid instrument for identifying variables maintaining self-injurious behavior.
    • The MAS can aid clinicians and educators in understanding the function of SIB in individuals with developmental disorders.
    • The MAS provides a practical tool for guiding behavioral interventions.
