Understanding the extent and nature of a woman's substance use disorder and its interaction with other life areas is essential for careful diagnosis, appropriate case management, and successful treatment. This understanding begins during the screening and assessment process, which helps match the client with appropriate treatment services. To ensure that important information is …
How does a therapy treatment work?
Module 3 covers the issues of clinical assessment, diagnosis, and treatment. We will define assessment and then describe key issues such as reliability, validity, standardization, and specific methods that are used. In terms of clinical diagnosis, we will discuss the two main classification systems used around the world – the DSM-5 and ICD-10.
How effective is psychotherapy and is it worth it?
There are more men than women in treatment for substance use disorders. However, women are more likely to seek treatment for dependence on sedatives such as anti-anxiety and sleep medications.14 In addition, although men have historically been more likely to seek treatment for heroin use, the rate of women seeking treatment has increased in recent decades.154
What is the difference between Phase 2 and Phase 3 clinical trials?
Phase II trials test if one type of cancer responds to the new treatment. Phase III trials test if a new treatment is better than a standard treatment. Phase IV trials find more information about long-term benefits and side effects.
How can you determine the effectiveness of a treatment?
Ways of Assessing Effectiveness. The effectiveness of a particular therapeutic approach can be assessed in three ways: client testimonials, providers' perceptions, and empirical research.
How is treatment effect size determined?
CONTINUOUS MEASURES When a trial uses a continuous measure, such as blood pressure, the treatment effect is often calculated by measuring the difference in mean improvement in blood pressure between groups. In these cases (if the data are normally distributed), a t-test is commonly used.
What is a Phase 4 clinical trial?
Phase 4 trials are conducted to determine long-term safety and effectiveness and to identify adverse effects that may not have been apparent in prior trials. Phase 4 trials usually include thousands of participants. Related Term(s) Clinical Trial. Food and Drug Administration (FDA)
How do you explain effect size?
Effect size tells you how meaningful the relationship between variables or the difference between groups is. It indicates the practical significance of a research outcome. A large effect size means that a research finding has practical significance, while a small effect size indicates limited practical applications.Dec 22, 2020
How do you interpret effect size?
Cohen suggested that d = 0.2 be considered a 'small' effect size, 0.5 represents a 'medium' effect size and 0.8 a 'large' effect size. This means that if the difference between two groups' means is less than 0.2 standard deviations, the difference is negligible, even if it is statistically significant.
How do you determine effect size?
Generally, effect size is calculated by taking the difference between the two groups (e.g., the mean of treatment group minus the mean of the control group) and dividing it by the standard deviation of one of the groups.

Understanding the extent and nature of a woman’s substance use disorder and its interaction with other life areas is essential for careful diagnosis, appropriate case management, and successful treatment.
What should providers use to ensure that important information is obtained?
To ensure that important information is obtained, providers should use standardized screening and assessment instruments and interview protocols, some of which have been studied for their sensitivity, validity, and accuracy in identifying problems with women.
What are the three critical concepts of assessment?
The assessment process involves three critical concepts – reliability, validity, and standardization . Actually, these three are important to science in general. First, we want the assessment to be reliable or consistent. Outside of clinical assessment, when our car has an issue and we take it to the mechanic, we want to make sure that what one mechanic says is wrong with our car is the same as what another says, or even two others. If not, the measurement tools they use to assess cars are flawed. The same is true of a patient who is suffering from a mental disorder. If one mental health professional says the person suffers from major depressive disorder and another says the issue is borderline personality disorder, then there is an issue with the assessment tool being used (in this case, the DSM and more on that in a bit). Ensuring that two different raters are consistent in their assessment of patients is called interrater reliability. Another type of reliability occurs when a person takes a test one day, and then the same test on another day. We would expect the person’s answers to be consistent, which is called test-retest reliability. For example, let’s say the person takes the MMPI on Tuesday and then the same test on Friday. Unless something miraculous or tragic happened over the two days in between tests, the scores on the MMPI should be nearly identical to one another. What does identical mean? The score at test and the score at retest are correlated with one another. If the test is reliable, the correlation should be very high (remember, a correlation goes from -1.00 to +1.00, and positive means as one score goes up, so does the other, so the correlation for the two tests should be high on the positive side).
When was the DSM 5 published?
3.2.2.1. A brief history of the DSM. The DSM-5 was published in 2013 and took the place of the DSM IV-TR (TR means Text Revision; published in 2000), but the history of the DSM goes back to 1944 when the American Psychiatric Association published a predecessor of the DSM which was a “statistical classification of institutionalized mental patients” and “…was designed to improve communication about the types of patients cared for in these hospitals” (APA, 2013, p. 6). The DSM evolved through four major editions after World War II into a diagnostic classification system to be used psychiatrists and physicians, but also other mental health professionals. The Herculean task of revising the DSM began in 1999 when the APA embarked upon an evaluation of the strengths and weaknesses of the DSM in coordination with the World Health Organization (WHO) Division of Mental Health, the World Psychiatric Association, and the National Institute of Mental Health (NIMH). This collaboration resulted in the publication of a monograph in 2002 called A Research Agenda for DSM-V. From 2003 to 2008, the APA, WHO, NIMH, the National Institute on Drug Abuse (NIDA), and the National Institute on Alcoholism and Alcohol Abuse (NIAAA) convened 13 international DSM-5 research planning conferences “to review the world literature in specific diagnostic areas to prepare for revisions in developing both DSM-5 and the International Classification of Disease, 11th Revision (ICD-11)” (APA, 2013).
What is clinical diagnosis?
Clinical diagnosis is the process of using assessment data to determine if the pattern of symptoms the person presents with is consistent with the diagnostic criteria for a specific mental disorder outlined in an established classification system such as the DSM-5 or I CD-10 (both will be described shortly). Any diagnosis should have clinical utility, meaning it aids the mental health professional in determining prognosis, the treatment plan, and possible outcomes of treatment (APA, 2013). Receiving a diagnosis does not necessarily mean the person requires treatment. This decision is made based upon how severe the symptoms are, level of distress caused by the symptoms, symptom salience such as expressing suicidal ideation, risks and benefits of treatment, disability, and other factors (APA, 2013). Likewise, a patient may not meet the full criteria for a diagnosis but require treatment nonetheless.

How does shock wave lithotripsy work?
Extracorporeal shock wave lithotripsy. All shock wave lithotripsy machines deliver shock waves through the skin to the stone in the kidney. Most but not all of the energy from the shock wave is delivered to the stone. Stone size is the greatest predictor of ESWL success. Generally:
What is the first step in a kidney stone evaluation?
If your symptoms suggest kidney stones, imaging is often the first step in an evaluation. For many years the standard of care was a type of abdominal x-ray called an intravenous pyelogram (IVP). In most medical centers, this has been replaced by a type of computed tomography (CT) called unenhanced helical CT scanning.
How long does it take for a ureteral stent to be removed?
A ureteral stent often minimizes any problems associated with steinstrasse. The stent is removed in a few days or weeks. A small percentage of patients undergoing ESWL develop hypertension, although the mechanism is not well understood.
What are the complications of ESWL?
The possible complications of ESWL include: 1 Injury to kidney tissue, such as bruising (hematoma), can occur in a small number of cases, but usually heals without additional treatment. 2 Fragmented stones may accumulate in the ureter and form an obstruction. This is known as a steinstrasse (“street of stones”). A ureteral stent often minimizes any problems associated with steinstrasse. The stent is removed in a few days or weeks. 3 A small percentage of patients undergoing ESWL develop hypertension, although the mechanism is not well understood. 4 An increased risk of diabetes mellitus following ESWL has also been reported. However, these results were not confirmed by a large population study done at the same institution.
What is the SSD for ESWL?
The urologist will calculate the skin-to-stone distance (SSD) to help determine whether this treatment is likely to be effective. The possible complications of ESWL include: Injury to kidney tissue, such as bruising (hematoma), can occur in a small number of cases, but usually heals without additional treatment.
How long does a postoperative stent last?
A postoperative stent can be placed for a few days at the discretion of the urologist. Complications are infrequent, but may include injury to or narrowing of the ureter, as well as sepsis.
How do you get kidney stones out of your kidney?
Using ultrasound or fluoroscopic guidance, a surgeon gains access to kidney stones through a small incision in the lower back during percutaneous nephrolithotripsy. A power source, such as ultrasound or laser, breaks the stones into fragments, which are flushed out of the kidney through an external tube or internal stent.
