Activity level: a comparison between actometer scores and observer ratings.

T M Stevens, M J Kupst, B G Suran

    Journal of Abnormal Child Psychology
    |June 1, 1978
    PubMed
    Summary

    Activity levels in boys were measured using actometers and observer ratings across different settings. Observer ratings showed context-specific correlations with measured activity, impacting hyperactivity assessments.

    Area of Science:

    • Child Psychology
    • Behavioral Science
    • Clinical Assessment

    Background:

    • Assessing activity level and hyperactivity in children is crucial for diagnosis and treatment.
    • Previous research highlights challenges in obtaining reliable and valid measures of child activity.
    • Understanding situational specificity in activity assessment is essential for accurate evaluation.

    Purpose of the Study:

    • To investigate the situation-specific relationships between actometer-measured activity and observer ratings in prepubescent boys.
    • To compare the validity of activity ratings from mothers versus clinical staff across different environments.
    • To examine interrater reliability among clinical staff in assessing children's activity levels.

    Main Methods:

    • Actometer measurements of activity were collected from 13 boys (aged 9-13) in classroom, gym, woodshop, and group therapy settings.

  • Mothers provided activity ratings using the Werry scale; clinical staff used the Davids scale.
  • Correlations were calculated between actometer data, observer ratings, and interrater reliability.
  • Main Results:

    • Clinical staff ratings significantly correlated with classroom actometer activity (r = .49 to .73).
    • Mothers' ratings significantly correlated with gym (r = .67) and woodshop (r = .77) actometer activity, and overall activity (r = .65).
    • Five of six clinical staff demonstrated significant interrater reliability (r = .58 to .83).

    Conclusions:

    • Observer ratings of child activity are situationally specific, influenced by the rater's observational context.
    • Mothers' ratings may be more sensitive to activity in less structured settings (gym, woodshop).
    • Clinical staff ratings are more aligned with activity in structured settings like the classroom, informing hyperactivity assessment strategies.
