An Analysis of Behavioral Health Service Encounters by the White Mountain Apache and the Navajo Nation in the American State of Arizona
This research investigated the utililization of behavioral health servies by the White Mountain Apache and Navajo tribal nations, as compared to non-tribal local populations.
An analysis of the utilization of service encounters, program eligibility and the penetration ratio of publically funded behavioral and mental health care services for the rural northern tier of the American state of Arizona was conducted. The focus was on comparing and contrasting the usage of services by members of the White Mountain Apache and of the Navajo Nation through the tribal behavioral health care authorities with the non-tribal authority.
The Apache and the Navajo had median penetration scores of 1.8% and 0.7% for combined services, as compared to the non-tribal authority rate of 14.12% (p=0.000). Analysis showed that there were statistically important differences (p=0.000) in service encounters, eligibility and penetration between the tribal and non-tribal behavioral health care recipients. Similarities were found in comparing the Apache and the Navajo in the treatment categories of serious mental illness (p=0.18) and substance abuse (p=0.41) although the actual penetration rates were quite low (<1%). The median child care penetration ratios were very low and statistically different when the Apache (1.46%) and Navajo (0.30%) were compared.
Additionally, the effect of raising the public mental health care eligibility rules on July 7, 2011, were clearly observable, showing a 27.14% drop in adult eligibility over a 18 month period.
