title: Medicaid provisions and the US mental health industry composition.
abstract: BACKGROUND
  Medicaid is the largest payer for mental health (MH) services.
  
  
  OBJECTIVE
  This study examines associations between Medicaid provisions and the MH industry composition.
  
  
  METHODS
  Medicaid data derived from the Centers for Medicare and Medicaid Services. MH facility gross payroll and occupational employment data derived from the Bureau of Labor Statistics. State fixed-effects regression models are performed to examine associations.
  
  
  RESULTS
  In the 1999-2009 period, per-capita gross payroll gains are largest for residential MH and substance abuse (SA) facilities and MH practitioner offices, followed by MH clinics and physician offices. Likewise, occupational employment gains per 100 000 people are largest for MH and SA social workers and MH counselors, followed by psychiatrists and psychologists. The Medicaid beneficiary rate is related with gross payroll gains at residential MH and SA facilities (p < 0.001) and MH clinics (p < 0.001), and with employment gains for MH and SA social workers (p < 0.001) and MH counselors (p < 0.001). Smaller effect sizes exist with MH physician offices (p < 0.05) and psychiatric hospitals' (p < 0.01) gross payroll. No statistically significant relationship exists between the Medicaid beneficiary rate and psychiatrist and psychologist employment.
  
  
  CONCLUSIONS
  Medicaid provisions are related with the MH industry composition. An imbalanced MH industry may lead to inadequate management of MH disorders.
