This study establishes norms for the Continuous Performance Test (CPT) in schizophrenia research. Findings highlight age, education, and sex as crucial factors for interpreting CPT performance in at-risk individuals.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Cognitive Psychology

Background:

  • The Continuous Performance Test (CPT) is a key tool for identifying schizophrenia vulnerability markers.
  • Establishing robust CPT norms is critical for accurate classification in genetic studies of schizophrenia.

Purpose of the Study:

  • To investigate the performance of adolescents and adults on the CPT under varying conditions.
  • To identify demographic factors influencing CPT performance and establish normative data.
  • To explore the relationship between CPT performance and schizotypy.

Main Methods:

  • 115 adolescents and 345 adults from the community were assessed on two CPT sessions (undegraded and 25% degraded).
  • Performance metrics including hit rate and sensitivity (d') were analyzed.

  • Demographic variables (age, education, sex) and schizotypy measures were recorded.

    • Main Results:

    • Older age correlated with lower hit rates and sensitivity (d'), while higher education showed the opposite trend.
    • Men exhibited higher hit rates and d' than women on the degraded CPT.
    • A practice effect was observed in 20-33% of participants during the second CPT session.
    • Poorer CPT performance was linked to higher scores on schizotypy measures.

    Conclusions:

    • Age, education, and sex norms are essential for interpreting CPT performance in schizophrenia research.
    • These findings provide valuable data for assessing CPT in clinical and high-risk populations.
    • Accurate normative data ensures reliable identification of schizophrenia vulnerability markers.
