1. What is the source of the data?
The population data are from the U.S. Census Bureau 2000 Census. Indiana census data can be down loaded from the Census Bureau website located at http://www2.census.gov/census_2000/datasets/Summary_File_1/
The mortality data are from the Indiana State Department of Health. The Indiana Division of Mental Health and Addiction requested use of these data and received formal approval to use the data on this website.
The source of the arrest data is the Federal Bureau of Investigations Uniform Crime Report. The Indiana Division of Mental Health and Addiction obtained these data by request from the Indiana Criminal Justice Institute.
The treatment admission and episode data are from the Indiana Division of Mental Health and Addiction, the developer of this website.
The school suspension, expulsion and drop out data are from the Indiana Department of Education available at http://doe.state.in.us/.
The Indiana Adult Household Survey was collected in 2003 as part of the State Treatment Needs Assessment Project, with funds provided to the Indiana Division of Mental Health and Addiction from the Center for Substance Abuse Treatment’s Substance Abuse and Mental Health Services Administration.
2. Why examine treatment data according to unique clients and duplicated clients?
At this website, the treatment episode data are examined in two ways. To examine treatment according to unique clients means a client is counted only once, regardless of the number of treatment admissions or episodes in a year. The value of unique client data is that it provides a profile of clients served, in this case by county. Furthermore, treatment episodes for unique clients allow us to show the rates of clients treated, determined by the number or clients treated divided by the corresponding population base for each county.
To examine treatment according to duplicated clients’ means that each client treatment admission or episode is counted in a year. The value of duplicated client data is that it is useful for services analysis and capacity planning. Unduplicated treatment episode and admissions data show patterns and amounts of treatment services that are actually delivered, but not information on the actual capacity of programs in a service area.
3. What is treatment modality?
Treatment modality refers to the type of services the client received. The eight types of services are as follows:
1. Detoxification, 24-hour Service -Hospital Inpatient
2. Detoxification 24-hour Service --Free-Standing Residential
3. Rehabilitation/Residential –Hospital (other than detoxification)
4. Rehabilitation/Residential --Short Term (30 days or fewer)
5. Rehabilitation/Residential --Long Term (more than 30 days)
6. Ambulatory –Intensive Outpatient
7. Ambulatory --Non-Intensive Outpatient
8. Ambulatory –Detoxification
4. What is a state fiscal year?
The state fiscal year begins July 1 and ends June 30. For instance, SFY 2001 began July 1, 2000 and ended June 30, 2001.
5. What is the difference between a frequency, percentage and a rate?
A frequency is an actual count of the number of cases. Percentage is the occurrence of an event expressed per 100 cases. For example, 25% refers to 25 out of 100 cases. Rate is the occurrence of an event expressed per unit of size of the population, which it is observed. For instance, death or mortality rates are usually expressed per 100,000, over a given period, usually 1 year.
6. What is primary and secondary drug of abuse?
Primary drug of abuse is the drug type that caused the most dysfunction, and secondary drug is the drug type (if any) that has resulted in a lesser degree of dysfunction than the primary drug of abuse. The drugs of abuse categories are alcohol, marijuana/hashish, cocaine/crack, opiates, amphetamines, sedatives, inhalants, hallucinogens, over-the-counter drugs, and others.
Crude rate is the occurrence of an event per the total size of the population.
Almost all causes of death occur at different rates in different age groups. Thus, the age distribution will determine what the most common causes of death in a community will be. Age-adjustment changes the amount that each age group contributes to the overall rate in each community, so that the overall rates are based on the same age distribution. This is done by multiplying age-specific rates per 100,000 by age-specific weights, which are proportions of the 2000 U.S. population within each age-group. Finally, the weighted rates are summed across the age groups to give the age-adjusted rate. 1
9. How are age adjusted rates used?
Age adjusted rates are standardized so that the relationship between age and particular causes of death has been statistically eliminated. These rates allow communities with different age distributions to compare causes of death. Age –adjusted rates should be viewed as relative indexes rather than actual measures of occurrence. 2
