Praxis Study Guide (Part 3) Flashcards
What is the research design in which performances of separate groups of subjects are measured and comparisons are then made between the two groups? Each subject has an equal probability of being assigned to either the experimental or control group.
Between-subject Designs
What is the research design in which performances of the same group are compared in different conditions and/or in different situations? Presentation of the experimental treatment conditions to the subjects is in random order.
Within-subject Designs
What occurs when an experimenter purposely attempts to match members of two groups based on all extraneous variables relevant to the experiment?
Subject Matching
What is the technique that enables the researcher to be able to control and measure sequencing effects by testing different participants in different orders?
Counterbalancing
What may occur when subjects participate in several conditions (i.e., subjects who participated in an earlier condition may affect their performance in subsequent)?
Sequencing Effect
In what research design is a baseline condition established, treatment of intervention to effect some sort of change is introduced, and treatment is removed to see if a return to baseline occurs?
ABA Design
In what research design is a baseline condition established, treatment of intervention to effect some sort of change is introduced, treatment is removed, and treatment is re-introduced?
ABAB Design
What is the technique of selecting individuals or a group of individuals from a population to use in research studies (probability and non-probability samples)?
Sampling Method
In which probability sample is every member of a population chosen randomly and has an equal chance?
Simple Random Sampling
In which probability sample are sample members chosen at regular intervals every nth number?
Systemic Sampling
In which probability sample is the population divided into subgroups before random selection?
Stratified Random Sampling
In which probability sample is the population divided into clusters based on demographics (e.g., location)?
Cluster Sampling
In which probability sample is every member of the population chosen randomly and has an equal chance?
Multistage Sampling
In which non-probability sample is specific individuals chosen to participate?
Purposive Sampling
In which non-probability sample do the participants depend on the ease of access and proximity?
Convenience Sampling
Internal clinical evidence, external research evidence, and patient preferences make up what?
Evidence-Based Practice
What level of evidence describes a systematic review/meta-analysis of all relevant RCTs? 3+ Good quality randomized controlled trials with similar results.
Level I
What level of evidence describes a 1+ well-designed randomized controlled trial(s)?
Level II
What level of evidence describes well-designed non-randomized quasi-experimental studies?
Level III
What level of evidence describes well-designed case-control or cohort studies?
Level IV
What level of evidence describes systematic reviews of descriptive and qualitative studies?
Level V
What level of evidence describes a single descriptive or qualitative study?
Level VI
What level of evidence describes an expert opinion and/or reports of expert committees?
Level VII
What is the classification framework used to guide clinical practice? It was developed by World Health Organization (WHO) and published in 2001. The health condition is the disorder or disease. The body functions and structures describe the anatomy and physiology. The environmental factors describe how the deficit influences the individual’s life and experiences. The activities and participation component describes how the deficit limits the individual’s activities and restricts their participation.
International Classification of Functioning, Disability, and Health (ICF)
What is the study of factors that determine the prevalence and incidence of diseases? It may provide useful information for the cause or guidance for treatment/recovery.
Epidemology
What is the term for how widespread a disorder is in the current population? It is the number of individuals with a particular disease/disorder at a given time. For example, it is an assessment of the overall burden of a condition on a population.
Prevalence
What is the term for the rate of individuals who developed a disease/disorder? It is the occurrence of new cases, typically reported within a given time. For example, it could be the number of new cases per year.
Incidence
What is the study of the cause and/or origin of disease?
Etiology
What assessment is always standardized? It compares individual performance to a group standard. It compares people that are the same age, grade, etc., and assesses individual performance to the “norm.”
Norm-Referenced
What assessment may or may not be standardized? It determines individual mastery of a particular skill(s). It identifies what a client can or can not do and there is not a group performance comparison.
Criterion-Referenced
What type of testing includes a standard set of procedures for administrating/scoring? It is usually norm-referenced.
Standardized Testing
What term indicates how many standard deviations a raw score is from the mean?
Standard “Z” Score
What is the term for the percent of people scoring at or below a certain score?
Percentile Rank
What occurs when there is no statistical difference/relationship between groups among variables?
Null Hypothesis
What is the term for the actual scores earned?
Raw Scores
What is the extent to which scores deviate from the mean or average scores?
Standard Deviation
What is the degree to which an assessment measures what it purports to measure?
Validity
What term indicates that a test looks like it assesses what is says it does?
Face Validity
