Area of Science:

  • Health Psychology
  • Psychometric Validation
  • Occupational Health

Background:

  • The Reduced Laffrey Health Conception Scale (RLHCS) is a key instrument for assessing health perceptions.
  • Previous research established a two-factor structure for the RLHCS in factory workers.
  • Replication is essential to confirm psychometric properties across diverse occupational groups.

Purpose of the Study:

  • To replicate the factor structure of the RLHCS in independent samples of construction workers.
  • To test the psychometric properties and factor invariance of the RLHCS across different worker populations.
  • To provide further evidence for the validity and reliability of the RLHCS in occupational health research.

Main Methods:

  • Principal components factor analysis with direct oblimin rotation was employed.

  • Structural equation modeling was used to test the equality of covariance matrices.
  • Two independent samples of construction workers (N = 697 and N = 510) participated.

    • Main Results:

    • The two-factor structure (clinical health and overall wellness) of the RLHCS was successfully replicated.
    • Factor invariance was demonstrated across the factory worker sample and the two construction worker samples.
    • The scale's structure remained consistent, supporting its cross-sample applicability.

    Conclusions:

    • The RLHCS demonstrates robust psychometric properties and a stable two-factor structure in construction worker populations.
    • Factor invariance suggests the RLHCS can be reliably used to measure health conceptions across different occupational groups.
    • This replication strengthens the evidence base for the RLHCS in occupational health and psychometric research.
