Ch. 11: Assessment & Treatment: Principles of Evidence-Based Practice Flashcards
Evidence Based Practice
Form of practice that ensures that clients receive services that are known to be based on reliable and valid research and sound clinical judgment.
Screening
A brief procedure that helps determine whether a client should undergo further, more detailed assessment.
Case History
Yields detailed information that helps the clinician understand the client and his or her communication disorder and associated variables. Involves gathering information about the client’s family, health, education, occupation, and other variables such as cultural and linguistic factors. Emphasis depends on the age of the client and the nature of the disorder.
Prognosis
A professional judgment made about the future course of a disorder or disease. It is a predictive statement about what might happen under various future circumstances.
Factors Influencing Prognosis
- Severity of the disorder
- Client’s general health
- The physiological course of an underlying disease
- Time of intervention
- Quantity, quality, and intensity of treatment offered
- Consistency with which treatment is received
- Family support for the client and participation in the treatment process
- Client’s motivation to work hard in treatment and outside the treatment setting
- Social reinforcement for maintaining gains made in treatment
- Client and family’s religious and cultural beliefs about the necessity for and efficacy of treatment
Hearing Screening
A quick procedure to determine whether a client can be assumed to have normal hearing or needs to be more thoroughly evaluated by an audiologist.
Orofacial Examination
An evaluation of the oral and facial structures to identify or rule out obvious structural abnormalities that affect speech production, and therefore, may require medical attention or affect communication treatment.
Interview
Involves a face-to-face exchange with the client, family members, or both to obtain additional information given on the printed case history form. Can be used to obtain data or information, to inform the clients and their families, and to provide support. Should include:
- Orienting the interviewees to the nature of the interview
- Explaining why certain information is requested
- Not making the client feel rushed
- Listening
- Using appropriate verbal and nonverbal communication
- Assuring the client of (and maintaining) confidentiality
Rapport
Respect, trust, and a harmonious relationship between the clinician and the family. Also involves recognizing and accounting for cultural and linguistic variables that might influence the interview.
Speech and Language Sample
The primary means of assessing a client’s speech and language production. Many clinicians record the sample for further listening, and some clinicians videotape the sample. More naturalistic than standardized tests. Goal is to obtain a representative sample of the client’s speech-language production in naturalistic contexts that reflect the client’s everyday communication.
Multidisciplinary Teams
Team members represent multiple disciplines, but each member conducts his or her individual evaluation, writes a separate report, and has little interaction with other team members.
Transdisciplinary Teams
Multiple specialists work together in the initial assessment, but only one or two team members provide services.
Interdisciplinary Team
Team members from multiple disciplines interact and use each other’s suggestions and information in interpreting data. The team collaboratively writes the evaluation report and intervention plan.
Standardized Test
A test that is systematic. Has explicit directions and strict controls about what the examiner must say and do. Specific stimuli are used, and there are explicit rules for scoring the test. The goal is to ensure that the behaviors being measured are not influenced by the examiner’s biases. Administration should be uniform across all examiners. Results yield quantitative information, allowing the client’s performance to be compared to peer performance that was sampled in the standardization process. A test can be standardized without being norm-referenced. Limitations include inadequate and non-diverse sampling.
Norm-Referenced Test
Purpose of this kind of test is to compare the individual client’s score to the average score of the normative group. This allows the clinician to determine if the client has a problem, if the problem is clinically significant, and whether the problem warrants intervention. The authors select tasks that they believe are valid in measuring certain behaviors and administer those tasks to groups of subjects who are thought to be representative of the population. The performance of the large sample is analyzed, resulting in normative data for specific age groups.
Norms
Represent the average performance of a typical group of people (typically children), sampled at different age levels during the standardization of a test.
Raw Scores
The actual scores earned on a test. Typically converted into a standard score.
Distributions
Yield measures of the client’s performance compared to the performance of the normative sample. Used to compare the client’s performance to that of a normative group.
Standard Deviation
The extent to which scores deviate from the mean or average score. Reflects the variability of all of the scores of the normative sample.
Percentile Ranks
Concerted scores that show the percentage of subjects who scored at or below a specific raw score. Use percentile points to express a client’s score relative to the normal sample. 50th percentile is equivalent to the mean and the median.
Age Equivalency
Scores that show the chronological age for which a raw score is the mean score in the standardization sample.
Functional Assessment
Purpose is to evaluate a client’s day-to-day communication skills in naturalistic, socially meaningful contexts. Does not depend on standardized test scores. Requires the clinician to make targets, procedures, and settings of assessment as naturalistic as possible.
Individualized/Client-Specific Procedures
Procedures that are a preferred alternative to standardized tests. Form a valid basis for developing client-specific treatments. These procedures use the evocation of speech-language samples over time, by means of culturally appropriate client-specific materials instead of standard stimuli. Baselines before starting treatment are another valid pretreatment measure of communication skills.
Criterion-Referenced Testing
A form of assessment that minimizes the role of standardized test scores in assessing skills. The performance assessed trough any means—including even standardized tests—is evaluated not against the statistical norms, but against a standard of performance selected by the clinician. This approach gives greater flexibility to the clinician to set the criterion that may be educationally and clinically meaningful, this avoiding a more rigid comparative evaluation against the test norms. Allows for more in-depth evaluation of the client.
