THE PSYCHIATRIC EVALUATION AND EVIDENCE-BASED RATING SCALES

Assessment tools have two primary purposes: 1) to measure illness and diagnose clients, and 2) to measure a client’s response to treatment. Often, you will find that multiple assessment tools are designed to measure the same condition or response. Not all tools, however, are appropriate for use in all clinical situations. You must consider the strengths and weaknesses of each tool to select the appropriate assessment tool for your client. For this Discussion, as you examine the assessment tool assigned to you by the Course Instructor, consider its use in psychotherapy.

• Review this week’s Learning Resources and reflect on the insights they provide regarding psychiatric assessment and diagnosis.
• Consider the elements of the psychiatric interview, history, and examination.
• Consider the assessment tool assigned to you by the Course Instructor.

Post a brief explanation of three important components of the psychiatric interview and why you consider these elements important. Explain the psychometric properties of the rating scale you were assigned. Explain when it is appropriate to use this rating scale with clients during the psychiatric interview and how the scale is helpful to a nurse practitioner’s psychiatric assessment. Support your approach with evidence-based literature.

Three Important Components of a Psychiatric Interview

  1. Mental Status Examination (MSE): The MSE assesses an individual’s current mental state, including mood, affect, thought processes, speech patterns, behavior, and perception. It provides a snapshot of the person’s current functioning and helps identify potential mental health disorders (American Psychiatric Association, 2020).

Why it’s Important: The MSE is crucial for establishing rapport, gathering vital information about the presenting concerns, and identifying potential risks (suicide, self-harm). It allows the practitioner to tailor the interview and further assessment tools accordingly.

  1. History of Present Illness (HPI): The HPI delves into the details of the current presenting concern. It includes the onset, duration, severity, and any aggravating or alleviating factors.

Why it’s Important: Understanding the HPI helps determine the context of the presenting problem and identify potential triggers or contributing factors. It aids in differential diagnosis by narrowing down potential causes.

  1. Past Psychiatric History (PPH): The PPH explores any past mental health diagnoses, treatments, and hospitalizations. It also gathers information about family history of mental illness and substance use.

Why it’s Important: The PPH provides valuable context for understanding the current situation. It can reveal patterns or vulnerabilities that might contribute to the current issues.

Psychometric Properties of a Rating Scale (Replace with Your Assigned Tool)

Here, replace “[assigned rating scale]” with the specific tool your instructor assigned. Research the psychometric properties of that scale, including:

  • Reliability: This refers to the consistency of the scale’s scores. Does the scale produce similar results when administered repeatedly to the same individual?
  • Validity: This refers to the accuracy of the scale in measuring what it is supposed to measure. Does the scale effectively assess the intended construct (e.g., depression, anxiety)?
  • Standardization: This refers to whether the scale has established norms based on a representative population. Does the score on the scale have a clear meaning compared to a reference group?

When to Use the Rating Scale During a Psychiatric Interview

  • After the MSE and HPI: Once you have a basic understanding of the client’s situation, the rating scale can provide a more quantitative assessment of specific symptoms.
  • To Track Progress: The scale can be used at regular intervals during treatment to monitor response and adjust interventions as needed.

How the Scale is Helpful for a Nurse Practitioner’s Assessment

  • Provides Objective Data: The scale offers a standardized measure, complementing the subjective information gathered in the interview.
  • Improves Diagnostic Accuracy: Quantitative data from the scale can support clinical judgment in differential diagnosis.
  • Tracks Treatment Progress: The scale helps monitor symptom severity over time, informing treatment decisions and providing evidence of effectiveness.

Evidence-Based Support:

  • American Psychiatric Association. (2020). Diagnostic and statistical manual of mental disorders (5th ed.). [Text Revision].

Remember to replace the bracketed information with the details specific to your assigned assessment tool. By incorporating this information, you can build a strong response that demonstrates your understanding of the psychiatric interview, the importance of psychometric properties, and the utility of rating scales in the context of a nurse practitioner’s assessment.
