psych asess Flashcards
1
Q
- What are the four key assumptions of psychological testing?
A
- People differ, that the trait can be measured, traits are stable, and these measures relate to actual behaviour
2
Q
- What defines a test?
A
- It is a procedure or device that yiels info about behave or cog, only a sample is tested, it is standardised, and the info is quantified
3
Q
- What are the four main stages of testing?
A
- Initial referral, test selection, a formal assessment, and then feedback
4
Q
- What other assessment methods can complement testing?
A
- Interview, other people in the person’s life, behavioral observation,
5
Q
- What is the structure of an assessment report?
A
- Identifying data, referral q, history, behaviour observation, list of tests or procedures undertaken, test findings and interpretation, summary and conclusion, then recommendations,
6
Q
- Recommendations for the client should be…
A

7
Q
- Good references for looking about tests
A
- Test catalogue, test manuals, professional books, reference volumes, journals, and online databases
8
Q
- What is the premise of classical test theory?
A
- A person’s observed score in a test is the sum of the true score and error
9
Q
- What is total variability?
A
- Population variability of scores, the true variance plus error variance
10
Q
- True variance and error variance refers to what?
A
- The variation in a collection of scores
11
Q

A
- Noise levels, time of day, the environment in general
12
Q
- What is random error in testing?
A
- Error that cannot be predicted
13
Q
- What are sources of measurement error?
A
- Test construction, test administration (environment, examiner, test-taker), scoring and interpretation, sampling, methodological (test training, unstandardised, vague questions, biased questions)
14
Q
- What is reliability?
A
- The variance attributed to true variance within the total variance
15
Q
- What is a disadvantage to classical test theory?
A
- Assumes all items on tests have equal weight
16
Q
- What is the advantage of item response theory?
A
- It considers difficulty and discrimination
17
Q
- What is difficulty?
A
- The degree to which an item is hard or easy
18
Q

A
- Shows an estimate of reliability over time
20
Q
- What is a parallel form?
A
- Two versions of a test are parallel if their means and variances of test scores are equal
21
Q

22
Q
- What is a split-half reliability?
A
- Dividing a test in half and seeing whether the scores on both halves correlate with each other using spearman-brown
23
Q
- What is the kuder-richardson used for?
A
- Tests the degree to which items in a test have inter-item consistency, meaning they are measuring the same thing
24
Q
- What are intra-class and cohen’s kappa used for?
A
- Intraclass is used to rate inter-scorer reliability on continuous items and cohen’s kappa is used for categorical items

28
Q
- What is Lawshe’s content validity ratio?
A
- Expert panel elected, items are rated as essential, useful but unessential and not necessary, and the content validity formula is tehn used to calculate the score. If the cvr score is half rated essential it is zero, if it is positive more than half, and if negative less than half
29
Q
- What is uncontaminated criterion validity?
A
- If a variable is used in the test to calculate the variable, it cannot be used to compare it to
30
Q
- What is concurrent criterion validity?
A
- Degree to which the criterion is related to an outcome measured at the same time
31
Q
- What is predictive criterion validity?
A
- The extent to which a test score predicts a future outcome measured
32
Q
- What are 6 types of construct validity?
A
- Homogeneity, evidence of changing with age, evidence from pretest-post test scores, evidence from distinct groups. Convergent evidence from older tests measuring similar constructs, and descriminant evidence showing the relationship on scores that the test scores shouldn’t’ be related to
33
Q
- What is the utility of tests?
A
- The psychometric soundness (validity), the cost of time, money training, ethic wise, and the benefits of the test such as better data, reliability, good for particular groups, cutting edge and increased validity
34
Q
- What is test bias?
A
- Bias is a factor inherent in a test that systematically prevents impartial measurement
35
Q
- What is fairness in tests?
A
- Fairness is the extent to which a test is used in an impartial, just, and equitable way
36
Q
- What is a rating error?
A
- Rating error – judgement resulting from untintentional or intentional misuse of a rating scale e.g. central tendency due to avoiding extreme ratings, halo effect

41
Q
- What is the Angoff method of cut-scores?
A
- Judgments of experts averaged to yield cut-scores
42
Q
- What is the known groups method of cut scores and what is a problem with it?
A
- Find groups known to possess or not possess a trait and collect data on them on predictor of interest, then choose cut-scores based on what best discriminates between the groups. A problem is what groups to choose
43

55
Q
- Why is feedback important and what is it good for?
A
- People have a right to results and interpretations, need to know the limitations of the tests they’re taking, they need to be able to make informed decisions, beware of bias that can distort results, get clients feedback to make sure they understand, be aware of countertransferance/emotions towards patient
56

A
- Recognising culture and race as a strength and also thedifficulties and discrimination that people can face because of it, difficulties adapting, interpersonal or intergenerational conflict, impacts on their perspective, fam, friends and community perspective that can influence their experience of mental illness, and respecting their values, orientation and knowledge and practices derived from their social group
57

A
- Stages are irreversible, the sequence is invariant, and the r/s w progression through stages as chrono age increases w some variation around the average time
68
Q
- What is Jean Piaget’s theory?
A
- The sensorimotor stage which revolves around sensory input, lacking object permanence 0-2 months, preoperational is the use of words to symbolize without principles of convo 2-6, and concrete operation uses principles of conservation and rational thinking 7-12, formal operational – mature adult thinking in terms of cause and effect 12+
69
Q
- What is the information processing theory?/Luria
A
- Focuses on how info is processed, simultaneous processing – information is integrated and occurs all at once, and successive processing – info is individually processed in a logical sequence
(1) information made available by the environment is processed by a series of processing systems (e.g. attention, perception, short-term memory);
(2) these processing systems transform or alter the information in systematic ways;
(3) the aim of research is to specify the processes and structures that underlie cognitive performance;
(4) information processing in humans resembles that in computers.
