Analyze psychometric properties of assessment tools 150 150 Nyagu

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.

Learning Objectives
Students will:
Analyze psychometric properties of assessment tools
Evaluate appropriate use of assessment tools in psychotherapy
Compare assessment tools used in psychotherapy
Note: By Day 1 of this week, the Course Instructor will assign you to an assessment tool that is used in psychotherapy.

Week 2: Assessment and Diagnosis in Psychotherapy

“A sensitively crafted intake assessment can be a powerful therapeutic tool. It can establish rapport between patient and therapist, further the therapeutic alliance, alleviate anxiety, provide reassurance, and facilitate the flow of information necessary for an accurate diagnosis and appropriate treatment plan.”

—Pamela Bjorklund, clinical psychologist

Whether you are treating patients for physical ailments or clients for mental health issues, the assessment process is an inextricable part of health care. To properly diagnose clients and develop treatment plans, you must have a strong foundation in assessment. This includes a working knowledge of assessments that are available to aid in diagnosis, how to use these assessments, and how to select the most appropriate assessment based on a client’s presentation.

This week, as you explore assessment and diagnosis in psychotherapy, you examine assessment tools, including their psychometric properties and appropriate use.

Delirium Rating Scale Revised-98

According to Lee, Ryu, Lee, Kim, Shin, Kim, &and Trzepacz (2011), delirium is an acute psychiatric syndrome characterized with impairment of consciousness with a prominent disturbance of attention and deficits of other cognitive areas, perception, language, thought, motor behavior, sleep-wake cycle, and affective control (para.1). Delirium is common among hospitalized patients that are extremely ill, affecting approximately 25% of this population (Lee et al., 2011). A significant number of morbidity and increased mortality and length of hospitalization has been attributed to delirium. Because delirium is frequently under- or misdiagnosed and associated with poor outcomes, a precise and reliable instrument for the diagnosis and repeated evaluation of delirium is needed which leads to the creation of the Delirium Rating Scale (DRS) which objectively measures symptoms severity of delirium. The DRS has some limitations for use in phenomenological and treatment research because aspects of motor presentation and cognition are each captured in a single item, therefore, the DRS was then revised as the Delirium Rating Scale-Revised-98 (DRS-R98) to compensate for the deficiencies of the DRS (Kato, Kishi, Okuyama, Trzepacz, & Hosaka, 2010).

The Delirium Rating Scale -Revised-98 (DRS-R-98) is a 16-item, clinician-rated scale, with anchored item-descriptions corresponding to both symptoms and temporal aspects of delirium. The Severity scale has 13 items, each rated from 0 to 3, where the sum has a maximum of 39 points, and where higher scores indicate greater severity of delirium (Sharma, Malhotra, Grover, & Jindal, 2017). Three additional items (rated from 0 to either 2 or 3) capture temporal course and attribution to an underlying etiology, and, when added to the sum of the 13 symptom-items, produce the DRS-R-98 Total score, which ranges from 0 to 46 (Thurber et al., 2015).

The Delirium Rating Scale -Revised-98 (DRS-R-98) can be used in evaluating phenomenology in medically ill patients. It can also be used to evaluate the efficacy of psychopharmacologic medications by assessing the severity ratings range from 0 to 3 indicating no impairment to severe impairment and higher scores indicating the higher severity of delirium (Sharma, Malhotra, Grover, & Jindal, 2017).

I agree with you that the DRS-R-98 is a revised version of the Delirium Rating Scale. According to Neefjes et al. (2019), the DRS-R-98 is the gold standard to evaluate the accuracy of the delirium observation screening scale because of its good psychometricqualitiesThe DRS-R-98 consists of 13 severity items that are scored from 0 (not present) to 3 points(severely present), and three diagnostic items are rated over the past 24 hours. The severity of the scores range from 0 to 39, and the overall scores range from 0 to 46. A skilled professional is the designated personnel that completes the DRS-R-98 questionnaire, and it takes about 10-15 minutes to complete (Neefjes et al., 2019). The severity scale of The DRS-R-98 has a significant benefit, and it can be used repeatedly to assess the response to delirium treatment. The DRS-R-98 has a well‑validated instrument with high interrater reliability, sensitivity, and specificity (Grover et al., 2019)

Geriatric Depression Scale
Collapse

The Geriatric Depression Scale is a self-report measure of depression in older adults. Users respond in a “Yes/No” format. The GDS was originally developed as a 30-item instrument. Since this version proved both time-consuming and difficult for some patients to complete, a 15-item version was developed. The shortened form is comprised of 15 items chosen from the Geriatric Depression Scale-Long Form. These 15 items were chosen because of their high correlation with depressive symptoms in previous validation studies. Of the 15 items, 10 indicate the presence of depression when answered positively while the other 5 are indicative of depression when answered negatively. This form can be completed in approximately 5 to 7 minutes, making it ideal for people who are easily fatigued or are limited in their ability to concentrate for longer periods of time (APA, 2020).

The Geriatric Depression Scale has been tested and used extensively with the elderly population. The GDS was found to have a 92% sensitivity and a 89% specificity when evaluated against diagnostic criteria. The validity and reliability of the tool have been supported through both clinical practice and research. In a validation study comparing the Long and Short Forms of the GDS for self-rating of symptoms of depression, both were successful in differentiating depressed from non-depressed adults with a high correlation. It is a useful screening tool in the clinical setting to facilitate assessment of depression in older adults especially when baseline measurements are compared to subsequent scores. The GDS may be used to monitor depression over time in all clinical settings. Any positive score above 5 on the GDS Short Form should prompt an in-depth psychological assessment and evaluation for suicidality (Greenberg, 2012).

The Geriatric Depression Scale is used in both the clinical setting and research setting to measure treatment response of geriatric patients with depression. A study by Papakostas (2015) used the Geriatric Depression Scale to obtain a baseline score and treatment follow-up for adults older than 65 starting antidepressants. The study concluded Geriatric Depression Scale scores showed duloxetine to be significantly more efficacious than placebo for improving depression. A study conducted by Luck-Sikorski et al., (2017), also used the GDS to determine depressive symptoms in adults greater than 75. The study concluded medication, psychotherapy, talking to friends and family, and exercise were the preferred treatment options for this population. Having a GDS score ≥ 6 significantly lowered the endorsement of some treatment options. Depressive symptoms influenced the preference for certain treatment options and also increase indecision in patients (Luck-Sikorski et al., 2017).
