"One of the most important elements in any service delivery system is the identification of needs, risks and strengths of children, youth and families. The accurate screening and assessment of these individuals and family systems are necessary to develop appropriate, individualized service packages. The use of valid screening and assessment tools will assure that safety risks (either to the public or the youth) are identified accurately and appropriate interventions are implemented, that urgent needs are recognized and dealt with quickly, and that services provided will likely result in positive outcomes ... Specifically, the decision to include each instrument is based on the following: 1) The instrument must be directly related to behavioral health, trauma and/or risk classification; and 2) The instrument must be age and developmentally appropriate; and 3) The instrument must be quantitative; and 4) The instrument must be researched-based; and 5) The instrument must have empirical evidence that supports its utility. All screening and assessment instruments in this reference guide have acceptable reliability and validity data associated with them and all have, to some degree, been independently evaluated" (p. 4). There are 12 juvenile screening instruments and 11 juvenile assessment instruments described. Information provided for each instrument is: a brief description of the instrument; the Colorado agency using it; the juvenile population being targeted; the instrument's purpose; when the instrument is administered; the decisions that can be made using the instrument; skills needed by those who give the assessment or screening; training required by this person; cost; and contact information with website (if available).
