ethical concerns w/ reversal designs
it would be unethical to remove an effective intervention that seems to be effectively reducing behaviors in a child or suicidal ideation, etc.
Sequencing effects
If you add an element or switch to a different intervention you cannot demonstrate efficacy as well, as you cannot remove the possible effects of the first intervention that you implemented (e.g., you cannot undo psychoeducation)
Analogue assessment
- Indirect measurement procedures that reflect how individuals behave in real-life situations
- Types: enactment, role play, video/audiotaped analogue, paper-pencil analogue, Behavioral Avoidance Test
- Advantages: best for screening and monitoring of treatment decisions, cost-effective, can help conceptualize
- Disadvantages: generalizability of results, procedures not standardized, instruction can produce bias
Baseline data
- purpose = use subjects performance in the absence of the IV (tx) as a basis for evaluating the effects of the IV
- allows opportunities for discovering that environmental events that control behavior (i.e. the antecedents and consequences)
- baseline data are also useful for helping to set the initial criteria for reinforcement
- ascending baseline data: can be a problem for studies in which you are trying to increase a behavior
- descending baseline data: can be a problem for students in which you are trying to decrease a behavior
- highly variable baseline: can be a problem bc typical level of behavior is unclear
functions of behavioral assessment
o Describe problem
o Identify controlling variables: ABC, SORCK - stimuli, organism, response, conseq., contingency
o Evaluate the impact on adaptive functioning
o Select treatment interventions
o Evaluate treatment outcome
methods of behavioral assessment
o Indirect: Behavioral interviews (based on idea that prob. Can be understood with learning principles—more emphasis on now), questionnaires/self-report, analogue situations (role play), self-monitoring, participant observation
• Potential problems: inaccuracy, reactivity, non-adherence
o Direct: observation in natural environment or electrophysiological (monitor couples heart rates)
• Potential problems: reactivity, reliability, comprehensiveness, cost-effectiveness
how is behavioral assessment different from traditional assessment
- traditional was idiographic (not comparing, but interpreting data, ex: Rorschach)
- behavioral assessment is now more nomothetic (compared to sample size, ex: MMPI)
behavioral case conceptualization steps
- Problem definition & formulation
- Translate problems into goals
- Identify intervention strategies
- Assess the effects of tx
why are case conceptualizations useful
o Helps to organize complex and sometimes contradictory information about a person
o Serves as a blueprint for guiding tx and a marker for change
o Represents a structure that enables the therapist to better understand the client
o May help therapist anticipate therapy-interfering events
o May help therapist develop greater empathy for client by deepening understanding of client
kinds of data needed to construct case conceptualization
o Client specific: bx, affect, cognition, biology
o Environmental: physical, social
what is a behavioral chain
- A series of discrete complex behaviors that must be performed in a certain order
- Stimuli throughout chain serve as conditioned reinforcers for the previous response and discriminative stimuli for the next response
- Forward: total task from beginning to end
- Backward chaining: starting with just put arms in shirt with shirt on, then start with shirt over head have to learn to pull down and put arms in
when is it best to intervene to break a bx chain
o Stimuli at beginning of chain are easiest to compete with because they are not reinforced as strongly; intervene with going to the store to buy cigarettes, not breathing in the lit cigarette
behavioral goals (considerations in selecting target bx)
o Select high priority goals
o For each goal identify for a given time frame: expected outcomes; more than expected outcomes and less than expected outcomes; much more than expected outcomes and much less than expected outcomes
o Most likely outcome would be considered tx success
o Can note what sources of information will be used to determine outcomes
o Challenge is to set goals that are realistic but not too easy/difficult
behavioral recording
o Event: record each instance of a bx occurring throughout day
o Interval: select period of time, divide time into smaller intervals, record presence of bx in each interval (partial, whole)
o Momentary time sampling: bx is recorded each time a signal occurs
o Narrative/structured diaries
behavioral interviews
o Operates on principle that client problems can be understood using learning principles
o Seeks to gather specific, detailed descriptions of observable events linked to problems (frequency, duration, timeline)
o Aims to delineate factors controlling bx (antecedents, consequences)
o Greater emphasis on present circumstances than distant past
o Hx of problem development is important
o Current life context
o Generate problem list
behavioral model
o Assumes that we are what we do
o Bx may be overt or covert
o Emphasis on bx rather than abstract constructs
o Human problems can be conceptualized in terms of excesses or deficits in bx
o Acknowledges role of heredity and biology
o Interest in the context in which bx occurs (ABC)
o Assumes a client needs to be taught new bx rather than have underlying psychological processes changed
o Tx procedures and techniques are ways of altering an individuals environment
o Methods and rationales can be described precisely
changing criterion design
• Conduct initial baseline observations on target behavior
• Implement a series of treatment phases
• Each treatment phase is associated with a step-wise change in the criterion for a target behavior
o Example: reinforce for 30 minutes of walking 2xs per week, switch to only reinforcing for 3 times per week
o Can be shaping like a more elaborate successive approximation or can be more frequency/intensity
o Each phase must be long enough for the behavior to stabilize
o Recommended to vary length of each
o The more times the target behavior changes to meet new criterion the stronger evidence that the behavior is under experimental control
