Substance Abuse

Pertaining to assessments and tools, please provide the concepts of validity, reliability, specificity and sensitivity as well as validity and discuss why each is so important to proper diagnosis and treatment planning. Give three different assessment or screening tools or devices that you might use in your work as a professional, and compare and contrast these measures on the dimensions of validity, reliability, specificity, sensitivity and validity. With those dimensions (Validity etc..) given the three tools you discussed, which one do you feel is stronger and why? How could you use the assessment tools you discussed in different types of settings? please include a discussion of the ethical, legal, individual and socio-cultural implications of screening and assessment to consider when selecting an appropriate tool.
