Single-item measures, especially faces scales, offer a valid and reliable method for assessing global concepts like pain and job satisfaction. These measures are economical and reduce participant burden, making them valuable research tools.

Area of Science:

  • Psychometrics
  • Health Services Research
  • Nursing Research

Background:

  • Single-item measures provide a concise alternative to multi-item instruments in research.
  • Their application is prevalent in studies assessing pain and job satisfaction.
  • Choosing between single-item and multi-item measures is a critical decision for researchers.

Purpose of the Study:

  • To review theoretical and empirical evidence supporting single-item measures.
  • To specifically examine graphic representational (faces) scales.
  • To evaluate the utility of single-item measures in research contexts.

Main Methods:

  • A comprehensive review of theoretical and empirical studies.
  • Discussion of reliability and validity considerations for single-item measures.

  • Comparative analysis of single-item versus multiple-item measurement approaches.

    • Main Results:

    • Single-item measures, particularly faces scales, demonstrate validity and reliability for global constructs.
    • Faces scales are an economical tool for assessing affective responses.
    • Evidence supports the use of single-item measures for concepts like pain and job satisfaction.

    Conclusions:

    • Single-item measures possess significant potential across diverse research applications.
    • Their ease of administration and reduced respondent burden are key advantages.
    • Nurse researchers are encouraged to integrate single-item measures into their methodological toolkit.
