Reliability and Validity01:29

Reliability and Validity

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.

Summary

The Sitting Balance Scale (SBS) is a new 11-item tool developed to assess sitting balance in frail, nonambulatory older adults. It demonstrates good reliability and validity for this population.

Area of Science:

  • Gerontology
  • Rehabilitation Science
  • Clinical Assessment

Background:

  • Frail older adults, particularly those who are nonambulatory, often experience challenges with sitting balance.
  • Existing balance measures may not adequately assess the functional abilities of this population, potentially leading to floor effects.

Purpose of the Study:

  • To develop and validate the Sitting Balance Scale (SBS) as a clinically useful tool for assessing sitting balance in frail, nonambulatory older adults.
  • To generate and refine items representing functional sitting balance abilities.
  • To establish the reliability and validity of the refined assessment.

Main Methods:

  • A multi-phase approach combining qualitative and quantitative methodologies.
  • Content development involved nominal group process, expert narratives, and literature review.
  • Item reduction utilized practical considerations, expert opinion, and statistical analysis, including internal consistency analysis of a 19-item version.

Main Results:

  • The final 11-item SBS demonstrated good internal consistency (α = 0.762).
  • Excellent intrarater reliability (ICC(3,1) = 0.96–0.99) and good interrater reliability (ICC(2,1) = 0.87) were established.
  • Construct and concurrent validity were confirmed through analysis of 156 scores.

Conclusions:

  • The 11-item SBS is a reliable and valid tool for assessing sitting balance in frail, primarily nonambulatory older adults.
  • The SBS addresses a gap in balance assessment for individuals with lower functional abilities, potentially avoiding floor effects.
  • Further validation with diverse and larger samples is recommended.
