A new 10-item scale effectively measures memory self-efficacy, showing similar validity to the original 33-item scale. This tool aids in understanding memory confidence and related psychological factors.

Area of Science:

  • Psychology
  • Gerontology
  • Cognitive Science

Background:

  • Memory self-efficacy is crucial for daily functioning and quality of life.
  • Existing measures, like the Memory Functioning Questionnaire (MFQ), can be lengthy.
  • Developing shorter, reliable scales is important for efficient assessment.

Purpose of the Study:

  • To develop and validate a concise 10-item scale for measuring memory self-efficacy.
  • To assess the reliability and construct validity of the new scale.
  • To identify predictors of memory self-efficacy.

Main Methods:

  • Utilized Rasch scaling procedures on data from 565 participants in the Long Beach Longitudinal Study.
  • Selected 10 items from the 33-item MFQ Frequency of Forgetting scale.

  • Analyzed correlations between scale scores and demographic/psychological variables.

    • Main Results:

    • A reliable 10-item scale for memory self-efficacy was successfully developed.
    • Female gender, conscientiousness, depression, and list recall predicted scores on the new scale.
    • The shortened scale demonstrated similar construct validity to the original, longer version.

    Conclusions:

    • The 10-item memory self-efficacy scale is a reliable and valid measure.
    • This shorter scale offers a practical alternative for assessing memory self-efficacy.
    • Understanding predictors like conscientiousness and depression can inform interventions.
