What is Construct validity?
Construct validity = extent to which an
operationalization adequately captures the
psychological construct of interest
➢ “Are you measuring what you think
you’re measuring?”
* Measure should make sense “on its face”
* Should be well grounded in existing
theoretical conceptions of the construct
* Should relate to other measures of
construct & predict future outcome
Ex. u can’t measure relationship compatibility via sock choice
What is a fixed-response questionnaire?
specific set of questions and possible responses predetermined by the researchers
➢ E.g., The Love Scale (Rubin, 1970
When are open-ended questions used?
Qualitative research
Another issue with memory: What is Sentiment override
global beliefs about the partner/relationship may colour perception and memory of specific interactions
➢ E.g., “how many times did your partner kiss you yesterday?”
➢ “I don’t remember, but he loves me and we have a good relationship, so must have been a lot”
Pros of self report?
Cons of self report?
Autobiographical memory is not
like a video recording
* It is, rather, a constructive process
➢ Pieces of remembered information +
current knowledge = narrative that
makes sense to us now
➢ Can leave out or amplify information to
support our current view of the partner
& relationship (memory bias)
Memories of past feelings guided by current feelings about the relationship
➢ If satisfaction in relationship improved: they’ll remember feeling more positively than they actually did
What is behavioural observation?
Gather data about relationship events without having to ask people who are
experiencing those events directly
➢ E.g., how do people in happy and distressed relationships differ in the way
they behave towards each other?
Can be anywhere (lab, at home, etc)
What is Inter-rater reliability ?
extent to which different coders agree on whether a specific behaviour has or has not occurred
A lot of behaviours require interpretation
➢ E.g., lighthearted joke vs. hostile sarcasm
Behavioural observations: Pros & cons
Pros
* Directly assess behaviours of interest
* Don’t have to rely on faulty memories
* Avoid social desirability bias
Cons
* Expensive, time and labour-intensive
* Reactivity = a change in behaviour caused
by the knowledge one is being observed
What is the threat of reactivity
a change in behaviour caused
by the knowledge one is being observed
What are Indirect measures?
reaction time = time it takes to respond a stimulus on screen
* Can be used to assess implicit attitudes = the automatic tendency to
associate a given stimulus with positive or negative feeling
IAT, What is the NEWLYWED game?
Flash partner and a positive / negative word
- Check their reaction time to both
If quicker with negative = implicit negative attitude
(These will not always align with explicit attitudes)
What happens when you run an IAT and then observe behaviour after?
Found that ppl with a more positive IAT also behaved more positively during the discussion (non-verbal behaviour= smiling / nodding)
What are the pros and cons of implicit measures?
Pros
* Avoid social desirability & reactivity problems
➢ Could be particularly useful for sensitive topics
Cons
* Big gap between construct of interest and operationalization
➢ Can we be sure that we are studying what we think we are studying
