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?

Content validity


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


How do you improve the validity

The test would need to be revised to produce a better match between scores on the new test and an established one
