The Agitated Behavior Scale (ABS) measures agitation in brain injury recovery. Agitation has three factors: aggression, disinhibition, and lability, with levels varying by time of day.

Area of Science:

  • Neuroscience
  • Rehabilitation Psychology
  • Clinical Psychology

Background:

  • The Agitated Behavior Scale (ABS) is a validated tool for assessing agitation in acute brain injury recovery.
  • Previous research supports the ABS's reliability, internal consistency, and concurrent validity.
  • The current study aims to further elucidate the factor structure of agitation and its temporal patterns.

Purpose of the Study:

  • To investigate the underlying factor structure of the Agitated Behavior Scale (ABS).
  • To examine the influence of time-of-day on the occurrence of agitation and its components.
  • To provide a more nuanced understanding of agitation in the context of acquired brain injury recovery.

Main Methods:

  • Confirmatory factor analysis was employed to determine the factor structure of the ABS.

Related Experiment Videos

  • Data were collected from 212 patients with acquired brain injury exhibiting agitation.
  • Agitation levels were analyzed across different nursing shifts to assess time-of-day effects.

    • Main Results:

    • Confirmatory factor analysis supported a one-factor model with three underlying dimensions: Aggression, Disinhibition, and Lability.
    • Overall agitation levels were lowest during the night shift.
    • The relationship between time-of-day and the specific factors of agitation showed variations, deviating from the overall pattern.

    Conclusions:

    • Agitation in acquired brain injury can be conceptualized as a general construct with distinct underlying factors.
    • Objective measurement and careful consideration of time-of-day are crucial when assessing and sampling agitated behaviors.
    • Findings inform clinical practice and future research on managing agitation during brain injury rehabilitation.
