The reliability and validity of in-person and remote behavioural screening tools for people with amyotrophic lateral sclerosis. | LitMetric

AI Article Synopsis

  • The study evaluated the effectiveness of various behavioral screening tools for people with ALS, examining their internal consistency and inter-relationships.
  • A total of 84 informants participated, completing both paper and online versions of the screenings, with results showing significant predictive relationships among most tools.
  • Overall, while the tools varied in psychometric qualities, the method of administration (online vs. paper) did not significantly influence total scores.

Article Abstract

Objective: This study aimed to assess the psychometric properties of and relationships between total scores on different screening tools assessing behavioural change for people with amyotrophic lateral sclerosis (ALS), and whether administering the screens as online questionnaires (rather than on paper, in-person) influences total scores.

Methods: The behavioural component of the Edinburgh Cognitive and Behavioural ALS Screen (ECASb); the behavioural component of the ALS Cognitive Behavioural Screen (ALS-CBSb), the ALS-Frontotemporal Dementia Questionnaire (ALS-FTD-Q), the Beaumont Behavioural Inventory (BBI), and the Motor Neuron Disease Behavioural Instrument (MiND-B) were administered to 35 informants on paper. Online questionnaire versions of the behavioural screens were administered to 49 informants. Forward stepwise linear regressions were conducted to assess whether scores on behavioural screens were predicted by scores on the other behavioural screens and to assess whether total scores were predicted by the mode of administration (paper or online) of the screens.

Results: Behavioural screening tools, except the ECASb, had good internal consistency but mixed item-total correlations. All regression models assessing whether behavioural screen scores predict other behavioural screen scores were significant. The BBI performed best and the ECASb performed worst in terms of their predictive relationships with other screening tools. The administration mode of the questionnaires did not significantly affect total scores.

Conclusions: The psychometric properties of the scales varied. The scales predicted each other's scores, supporting convergent validity. Online and paper versions performed similarly, and demographics did not predict scores.
