quality of assessments Flashcards
what are the conditions of an assessment?
- must be flexible (have a broad range of options beyond selecting frequency, interval, duration, and measurement strategies)
- must be rigorous (observation need to be made consistently)
what are natural vs. contrived trades, activities, and settings?
- performance is observed without intervening or structuring the situation for the client
- often not possible as who knows how long you’ll have to watch them for?
- best to select contrived tasks as it is easier to do than naturalistic
what is the natural environment vs. laboratory settings?
- naturalistic settings are real-life
- ideally, direct observations are made in a natural setting where clients normally are
- however, natural settings are often expensive
- usually real-life situations are used but something about them is contrived to allow observations to be made
what are obtrusive vs. unobtrusive assessments?
- obtrusive (clients are aware of the measurement process and that their behavior is being assessed)
- obtrusive could be reactive, meaning it could influence the performance of the client
- unobtrusive (clients are not aware of the measurement process)
- often unobtrusive assessment is not possible due to clients having to be informed of the intervention
what are human observers vs. automated recording?
- in most cases, humans assess behaviors
- with automated recording (recommended the most), humans are only involved when it comes to calibration of the machine
- often automated recording is better as it is not biased, can assess behavior more accurately, etc.
what are point-by-point agreement ratios?
- assesses whether there is an agreement of each instance of observed behavior
- uses discrete opportunities (number of trials, intervals, or correct answers)
- most useful in interval assessment
what is plotting agreement data?
- may be one observer (primary) observing the client each day and perhaps a second observer (secondary) also occurring the behavior
- usually only the data from the primary observer is plotted but data from a secondary observer may also be plotted to see similarities between them
- provides useful information about how closely the observers usually agreed in their totals for occurrences
what are conducing checks for agreement?
- agreement has to achieve an acceptable level before baseline observations are begin and has to maintain that level throughout the project
- ageeement has to be between 80-100%
- major factor of influence interconnects agreement is whether observers know that their agreement is being checked
- if they know their agreement is being checked, they may show higher agreement
what are the general guidelines for assessments?
- check agreement at least a few times in each phase (ex. baseline, intervention)
- calculate agreement during the project rather than when the project is over to see if any changes need to be made
- ensure the observers work independently from each other
- avoid conveying expectations to the observers about what the data should show
what are evaluating interventions?
- whatever measure is selected, it will need to be administered repeatedly for an ongoing basis overtime
- measure should be able to reflect change
- should reflect a continuous dimension, not binary
- measure should make sense for the assessment
what is the use of multiple measures?
- problems or subjects often have multiple components that can be measured
- different measurements can yield different results
what are the purposes of pre and post intervention assessments?
often easily obtained and can elaborate or expand on the operational definition of the observation measures.
what is a probe assessment?
- measures that are administered occasionally (rather than continuously) in other settings or at other times than those in which the intervention is conducted
- probes test whether there are other changes than those that served as the intervention focus
- probes see if whether the behavior carries over to other settings, is maintained, or whether another behavior has changed
how does one construct a recording sheet?
- look at sheets other have used
- arrange the sheets in the same way you scan or record the behavior
- use symbols or abbreviations when possible
what is observer drift?
- observers gradually depart from the original definitions of behavior
- can happen if observed become more lenient, more stringent, or less consistent in their definitions of behavior
