Like with many things, every assessment will present strengths and weaknesses. In addi-tion to it’s internal consistency, the strengths of the DAST assessment includes it’s low cost, short time to administer, variation of ways it can be administered, and it’s known to be valid and reliable (Giguère, 2017). The reliability, validity and different options for administering make theassessment useful for diverse populations. On the other hand, some of the weaknesses consist of the client not being honest about their use because of the way the questions are worded, and the possibility of the results being misinterpreted (The Gale Group Inc, 2001).The CAGE questionnaire is another useful screening tool for substance abuse. Initially, the CAGE instrument was used primarily for alcohol dependence, but the CAGE-AID was Adapted to Include Drug Use (AID). The four questions that are asked during the assessment consist of: “Have you ever tried to cut down on your drinking or drug use? Have people annoyedyou about your drinking or drug use? Have you ever felt guilty about your drinking or drug use? Have you ever had a drink or used drugs first thing in the morning to steady your nerves or to getrid of a hangover?” (Basu,Hazari & Parakh, 2016). The CAGE-AID is quick and easy to admin-ister, found to be a valid when diagnosing for substance abuse and substance dependence. A
Addiction Treatment Planweakness would be that the CAGE tends to focus in on alcohol or opioid users, which leaves a lot of the general population unable to use the instrument.When screening Marifel for co-occuring mental health issues, the counselor would use the Minnesota Multiphasic Personality Inventory Test, MMPI or the Post Traumatic Stress Disor-der.Post Traumatic Stress Disorder, PTSD “is the most prevalent psychopathological conse-quence of exposure to traumatic events“ (Lango, 2017). The individual constantly has thoughts or dreams about their traumatic experience. In Marifel’s case PTSD could be co-occurring with her substance abuse with opiates (Lango et al., 2017)). One of the best known treatments for PTSD is cognitive behavioral therapy. “Cognitive behavioral therapy revisits distressing ele-ments of the traumatic events and consequent avoidance and cognitive distortions” (Lewis, 2014). One of the great things about using CBT with Marifel is that it’s one of the best therapy for individuals that come from diverse backgrounds. For example, CBT doesn't emphasize shar-ing of feelings or expression of emotion because those are activities that clients may shy away from given their cultural or ethnic backgrounds (Lewis, 2014).The MMPI is one of the most used personality instruments. It’s used to help make psychi-atric diagnosis and decisions, to assist the psychologist with their overall view and perception of the clients personality, and to aid in coming up with a hypothesis about the clients challenges (Lewis, 2014). It consists of 567 questions, that require the client to answer using true or false.
