Summary

The Waring distribution best models psychiatric patient contact frequency, outperforming Poisson and negative binomial models. This offers superior analysis for comparing patient contact patterns across different psychiatric case registers.

Area of Science:

  • Epidemiology
  • Biostatistics
  • Psychiatric Research

Background:

  • Patient contact frequency is crucial for understanding psychiatric care.
  • Accurate statistical modeling is needed to analyze contact patterns in psychiatric case registers.

Purpose of the Study:

  • To evaluate three probabilistic models: Poisson, negative binomial, and Waring.
  • To determine the best model for analyzing patient contact distribution in psychiatric care.

Main Methods:

  • A longitudinal study analyzed patient contacts over 91 days.
  • Data from the South-Verona Psychiatric Case Register (1979-1991) was used.
  • Goodness-of-fit tests (chi-square) were applied to compare model performance.

Main Results:

Related Experiment Videos

  • The Waring distribution showed a non-significant chi-square result (25.31 with 19 df, p = 0.151), indicating a good fit.
  • Poisson and negative binomial distributions yielded significant results (p < 0.001), suggesting poor fit.
  • The Waring distribution's variance decomposition into random, endogenous, and exogenous factors was highlighted.

Conclusions:

  • The Waring distribution is the most suitable model for analyzing psychiatric patient contact frequency.
  • It enables detailed analysis of contact patterns and facilitates comparisons between different psychiatric registers.
  • The negative binomial model may be useful when the distribution's tail is less critical.
