Overview

Validation study demonstrates the One-item Loneliness scale effectively assesses loneliness, suggesting it may replace indirect scales.

Key Points

  • The One-item Loneliness scale (1iL) reliably measures loneliness with high retest reliability (rtt = .74).
  • Analysis of multi-rater data (N = 352) shows 1iL induces no more bias than established indirect loneliness scales.
  • The 1iL correlates strongly with the Three-Item Loneliness Scale (rtrue = .97), indicating effective assessment.
  • Findings support the unidimensional nature of loneliness as distinct from social disconnection.
