Reliability and Validity

12.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Area of Science:

  • Behavioral Psychology
  • Clinical Psychology
  • Applied Behavior Analysis

Background:

  • Problem behavior is often maintained by specific environmental contingencies.
  • Accurate identification of these maintaining variables is crucial for effective intervention.
  • The Functional Analysis Screening Tool (FAST) was developed to aid in this identification process.

Purpose of the Study:

  • To assess the interrater reliability of the FAST.
  • To evaluate the validity of the FAST by comparing its outcomes to functional analyses.
  • To explore the utility of the FAST in clinical settings.

Main Methods:

  • Study 1: Assessed interrater reliability of the FAST with 196 problem behaviors using independent raters.
  • Study 2: Assessed the validity of the FAST by comparing its outcomes with results from 69 functional analyses.
  • Data analysis included calculating mean item-by-item agreement and comparing FAST outcomes to functional analysis conditions.

Main Results:

  • Interrater agreement for FAST items averaged 71.5%, with a range of 53.3% to 84.5%.
  • Agreement on FAST outcomes (highest totals) was 64.8%.
  • The FAST score predicted the highest rate of problem behavior in functional analysis conditions in 63.8% of cases.

Conclusions:

  • The FAST demonstrates moderate interrater reliability and predictive validity for identifying problem behavior functions.
  • The FAST can be a useful screening tool in clinical interviews to guide functional behavior assessment.
  • Further research is needed to explore its limitations and optimize its application.
