This study introduces the K-SF-42, a new 42-item short form of the Arizona Life History Battery (ALHB). It offers a psychometrically validated alternative for cross-cultural research on life history strategies.

Area of Science:

  • Psychology
  • Evolutionary Psychology
  • Cross-Cultural Psychology

Background:

  • The Arizona Life History Battery (ALHB) is a comprehensive 199-item measure.
  • Existing short forms, like the Mini-K, have limitations for cross-cultural application.
  • Life history strategy is a key concept in understanding human behavior, including aggression.

Purpose of the Study:

  • To develop and validate a new, shorter version of the ALHB, named the K-SF-42.
  • To ensure the K-SF-42 demonstrates optimal psychometric performance across diverse cultural contexts.
  • To provide a tool for valid comparisons with the widely used Mini-K short form.

Main Methods:

  • Secondary data analysis of a five-nation cross-cultural survey using the ALHB.
  • Item selection based on the Cross-Sample Geometric Mean criterion for cross-cultural validity.
Keywords:
cross-cultural researchlife history theorypsychometrics

Related Experiment Videos

  • Focus on data collected across all five cultural replications for robust analysis.

    • Main Results:

    • Successful development of the K-SF-42, a 42-item short form derived from the original ALHB.
    • The K-SF-42 is designed for optimal performance across the sampled cultures.
    • The novel item selection method supports the cross-cultural validity of the new scale.

    Conclusions:

    • The K-SF-42 is a psychometrically sound and culturally adaptable alternative to existing short forms of the ALHB.
    • This new scale facilitates robust cross-cultural research on life history strategies and related behaviors.
    • The K-SF-42 has the potential to generalize to other modern industrial societies.
