Discussion postSubstance use screening

DQ 1 :What are the advantages and disadvantages of using standardized instruments to assess and diagnose clients?

Two lists are wanted and the second one is harder. Anchor both to named instruments, and separate screening from diagnosis, because most posts lose marks by treating an AUDIT score as a diagnosis.

Screening is not diagnosis, and PCN 501 is testing that

The prompt hands you a two-sided list and the sides are not equally difficult. Advantages come easily: standardisation, comparability across clients and across time, reduced reliance on a counsellor's impression, a defensible record, brevity that fits a first session, and a common language with referring physicians and payers. Write them, but write them attached to instruments you can name, because a post that says instruments are reliable and valid without naming one is indistinguishable from every other post in the forum. The AUDIT, the DAST, the CAGE, the ASSIST and the CRAFFT for adolescents are the obvious candidates, and each has a published cut-off and a known population it was normed on. Naming the norming population is what turns a generic advantage into a specific one, because it is also the hinge of the disadvantage half. The CAGE, for instance, was developed on hospital inpatients and asks about lifetime experience, which is why it performs poorly as a measure of current severity.

The disadvantages are where the marks are, and there is one distinction the assessor is almost certainly listening for. A screening instrument tells you whether to look further. It does not diagnose. Diagnosis under the DSM requires the clinical criteria applied by a qualified clinician, and a positive AUDIT is a reason to conduct that interview rather than a substitute for it. Around that, build the rest: cut-offs derived on populations unlike your client, self-report distorted by shame, minimisation or a mandated referral, cultural and language mismatch, literacy demands, a false sense of precision from a number, and the risk that a score becomes the client's label in the chart. Close on the practical resolution, which is that instruments belong inside a clinical interview rather than in place of one, and say who is qualified to make the diagnosis they point toward. In most agencies that is a licensed clinician and not the intake counsellor who administered the screen.

Likely learning objectives

Name specific screening instruments and the populations they were normed on.
Distinguish screening from diagnostic assessment.
Explain how self-report conditions distort instrument results.
State where a standardized instrument belongs in an intake process.

I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you. Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted. If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations. Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements. Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week. I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!
