    1. Has it been specifically tested in this age group?
    1. Next, discuss the predictive ability of the test. For instance, how do you know the test is reliable and valid? What are the reliability and validity values? What are the predictive values? Is it sensitive to measure what it has been developed to measure, for instance, HIV, or depression in older adults, or Lyme disease? Would you integrate this tool into your advanced practice based on the information you have read about the test, why or why not?

A Sample Answer For the Assignment: NR 503 Discussion Epidemiological Methods

Title: NR 503 Discussion Epidemiological Methods

Screening tools for Alcohol Misuse.

There are several tools used for detecting alcohol abuse with the most common being Alcohol Use Disorder Identification Test Consumption (AUDIT-C). AUDIT-C is a three-question test to evaluate a person’s daily alcohol use and takes about two minutes long. The questions address alcohol use, frequency, and frequency of having six or more drinks on each occasion (Higgins-Biddle et al., 2018).

AUDIT-C test was implemented by Higgins-Biddle during visits with college students during campus clinic for medical reasons. The test was used to identify alcohol misuse disorder and the students were offered resources along with counselling. With identification and interventions following the AUDIT-C test screening, it showed a decreased consumption of alcohol (Higgins-Biddle et al., 2018)

AUDIT-C test is appropriate for any group age 18 years and over and can be provided at a primary care appointment by a care provider (U.S. Preventative Service Task Force [USPSTF], 2018). When an individual is positive on the AUDIT-C test, then an Alcohol Use Disorder Identification Test (AUDIT) is administered and it consist of ten questions and take about five minutes to complete and one screening question is “How many times do you have more than 8 drinks a day for men, or more than 4 drinks/day for women or adults older than 65 years?

Predictivity Ability:

How can we tell if the test is reliable and valid? The (USPSTF) US Prevention Service Task Force claims that strong evidence of efficacy is derived from a quick behavioral change after a counselling session. The USPSTF study showed that for adults with risky or hazardous drinking habits that undergo an effective behavioral counselling support have reduced alcohol consumption and abuse. The Predictivity of the AUDIT screening and effective counselling shows improved adherence to the advised alcohol limit and a lower weekly alcohol consumption rate.

This study doesn’t provide sufficient evidence of study on how well brief behavioral counselling works for pregnant women who abuse alcohol or are alcoholic. The study has evidence on women with alcohol abuse problem that would like to get pregnant by reducing alcohol intake and stick with the counselling advice to set a drinking limit.

What are the reliability and validity values?

The intensity and interventions are defined by the USPSTF in three categories, 1. Very Brief single contact (5 minutes). 2. Brief Single contact (6-15 minutes), and 3. Brief Multiple contact (1 contact, each greater than 15 minutes). Research shows that very brief contact counselling has the list effectiveness while multi-contact with longer sessions has the strongest evidence of effectiveness. This study cannot be used to measure sensitivity compared to other studies on diseases, but it can be integrated into my advanced practice.  The study is effective for positive affect for risky and unhealthy drinking behaviors for adults and the brief behavioral counselling is most effective for the binge drinkers.

Alcoholism is a sensitive topic in society and alcohol consumption discussions are challenging especially to young adults. The practitioner should comfortably assess and treat patients at risk using the AUDIT screening since they are user-friendly and straightforward tools (Zimmerman et el, 2018).
