RM: Self reports Flashcards
What are self reports?
-techniques where ppts provide info about themselves (thoughts/opinions/feelings)
What is a psychometric measure?
-tests that have been assessed (statistically tested) for (internal) validity and (concurrent) reliability
Strengths of self-reports?
-ppts describe their own experiences: rich qualitative data (about complex human behaviour)
-helps explain the reasons behind behaviour
-an easy way to gather a large amount of data
-increases generalisability.
-can ask people hypothetical questions
Limitations of self-reports?
-social desirability bias- untruthful responses/lower result validity
-only useful if the ppts are willing to disclose the information
-rely on ppts to have the introspective ability to understand their thoughts/feelings.
-acquiescence bias
-ppts may misinterpret the questions (subjective)
What are questionnaires?
-ppts given a pre-set number of questions to respond to
How can questionnaires be administered?
-person
-by post
-online
-to a group of ppts simultaneously
How are questionnaires designed?
-should progress from least-> most sensitive
-more general-> more specific
-q’s should not be influenced by previous ones
What type of questions are asked in a questionnaire?
-Likert scales (strongly disagree-> strongly agree)
-rating scales (1-10)
-closed questions (yes/no)
-open questions
What are closed questions?
-only a certain number of options available to answer
What data do closed questions collect?
-quantitative data
What are open questions?
-no set answers/no restrictions on what the ppts can say
-could lead to ideas for further investigation
What data do open questions collect?
-qualitative data
What are standardised instructions?
-a set of written/recorded instructions given
-all ppts receive them in the same way
Why are standardised instructions used?
-as a control to standardise the proceduce
-increases reliability and validity of the research
What are filler questions?
-q’s put into a questionnaire/interview to disguise the study’s aim
-reduce demand characteristics
