What are psychological tests?
standardised device for examining a person’s responses to specific stimuli, usually questions or problems.
What are norms?
the scores and corresponding percentile ranks of A large and representative sample from the population by which the test was designed.
What is random selection and random assignment? What validity is each?
Random selection – how you draw the sample of people for your study from the population as a whole. External validity (generalizability) of results i.e. it reflects how representative your sample is of the population it has been drawn.
Random assignment – how you assign the sample to different groups or treatments in your study. Internal validity (design of study), ensuring experimental groups are equivalent prior to the treatment.
What is reliability and validity?
Reliability – consistency of test scores. The ability of a test to yield same score for same individual through repeated testing.
Validity - ability of teat to measure and predict only what it is supposed to.
What is behavioural observation used for?
to measure the target behaviours of concern that have been established in the interview (target behaviours need to be clearly and objectively defined)
What is anecdotal observation?
observer records behaviours of interest, the antecedent conditions and consequences related to the clients’ natural environment
What is the interview structure / key components?
- Purpose of assessment
- Concerns of client
- Importance of concerns
- Present behaviour
- Antecedents of behaviours
- Consequences of behaviours
- Previous approaches
- Coping skills and resources
- Client’s perception of problem behaviour and distress
What are the important factors of unstructured interviews?
interviewer’s expression of warmth, sincerity, acceptance, and understanding.
What are sources of bias?
o Information variance – variation in the amount and type of info obtained due to different questions being asked.
o Halo effect- attribution of unrelated attributes from the impression gained.
o Confirmatory bias – tendency to ask qs to confirm a psychodynamic explanation
What is reactivity in self-monitoring?
Reactivity – act of self observation leading to behaviour change
o Level of reactivity increases with higher motivation, strong alignment of behaviour with goals, greater visibility of recording devices and higher freq of self recording.
What are the 6 steps for self monitoring?
- Intro to rationale for strategy
- Defining the response clearly
- Clearly defining how and when to record responses
- Charting responses so it can be seen visually
- Deciding where and how to display results (public may provide reinforcement from others but need for confidentiality and shame to be considered).
- Analyzing the data – discuss in therapeutic context to link goals and gains
