Flashcards in Validity of self-report techniques questions interviews and psychological tests Deck (20):
What is a psychological test
psychological test is a set of tests that measure some aspect of human behaviour
Name five types of psychological tests
IQ, personality, new scales, attitude scales, aptitude scales
When assessing the validity what are the 4 main considerations?
Social desirability bias, interviewer bias, leading questions, and content validity
What is social desirability bias
The participant may behave in the most socially acceptable way for the purposes of the research study
Is social desirability bias a participant effect or not?
Yes it is
What effect can and interviewer bias have and how
The interviewers Behaviour may affect or bias the answers. e.g. they may subtly and unconsciously tilt his head for example to encourage the correct answer to a test item when doing a face-to-face interview
What is the problem with leading questions?
If the question contains a suggestion that the expected answer than the answers provided wouldn't truly represent the participants thoughts and feelings
What will be the impact on the validity of the data if the questions are ambiguous?
The validity of the data will be lowered
What is content validity
Has the researcher measured what he intended to measure
If the questionnaire or interview or test is not measuring the intended quantity tent then any score or data will be meaningless and the measure will be classed as lacking what?
What is the ceiling effect
If all the questions on a test are easy then everyone will do well i.e. hit the ceiling
What is the floor effect
If all the questions are too hard everyone will do poorly and hit the floor
What are the five ways of assessing the validity
Lie scale, face validity, concurrent validity, predictive validity and construct validity
What is a lie scale?
A lie scale is a way to assess whether people are telling the truth so a few questions act as truth detectors. If the answer to those questions are unnaturally positive then the live scale may have a high result and cause you to be sceptical about the answers on the rest of the questionnaire
Give an example of a truth detector?
Are you always happy? Are you always positive?
What is face validity?
Base solidity concerns the issue of whether a self-report measure looks like it is measuring what the researcher intended to measure.
What is concurrent validity
What is concurrent validity? This can be established by comparing performance on a new self-report measure with a previously validated one on the same topic - if the new measure produces a similar outcome as the older one then this demonstrates the concurrent validity of the new measure
What is predictive validity
Their score would predict success on other related measures e.g. an intelligence test. Therefore we can check this out as a means of assessing the predictive validity of a measurement
What is construct validity
This is assessed by looking at the underlying constructs of a test. For example a questionnaire on aggression would need to reflect various key theoretical views in order to be valid
