Behavior “You can observe a lot by just watching.” Yogi Berra
Behavior • What people do • How people move and what they say, think, and feel • Not what people have (e.g., depression, anxiety, self-esteem)
Overt Behavior • Can be observed by others, at least theoretically • e.g., binge eating; bullying; illegal drug use; spousal abuse; time spent with child or spouse; time spent interacting by nursing home residents number of completed Tx tasks; number of times a parent compliments his or her child
Covert Behavior • Occurs within the individual and can not be observed directly by others • e.g., positive, self-deprecating, or irrational thoughts; time spent feeling anxious, under stress, or overwhelmed; time spent craving alcohol or drugs; time spent ruminating about some concern
Direct Observation Observation of overt behavior by outside observers
Self-Monitoring Systematic observation and recording by a person of his or her behavior or other experiences, either covert or overt • Thought records and similar forms that you can download and use in your practice: http://www.getselfhelp.co.uk/freedownloads2.htm
Ideal Characteristics of Behavioral Observation • Conducted in real-time • Conducted in the natural environment • Conducted repeatedly over time
Purposes • Pinpoint and define behaviors targeted for intervention • Explore and clarify the dynamic contexts in which targeted behaviors occur • Measure and monitor client progress
Decide What Dimension of Behavior to Measure • Counts (frequency) • Number of times a behavior occurs, usually within some time period (e.g., hour, day), ignoring the duration of the behavior • Duration • Length of time a behavior occurs
Counts • Used when the number of times a behavior occurs needs to be increased or decreased • Behavior must have a clear beginning and ending, and different occurrences must last about the same duration
Rate • Count per unit of time • Rate used if observation times differ • count / time
Duration • Used when the time a behavior occurs needs to be increased or decreased • Behavior must have a clear beginning and ending
Rate • Duration per unit of time • Rate used if observation times differ • duration / time
Additional Dimensions of Behavior • Response latency • Time it takes for a behavior to occur in relation to the occurrence of some stimulus • Interresponse time • Time between occurrence of two instances of the same response • Magnitude • Strength, intensity, or force of a behavior
Behavior Products • Effects or results of behaviors • e.g., urine toxicology analysis for drugs; completed school assignments; number of child safety risks in a home
Decide Whether to Collect Contextual Information • Clarify environmental conditions that cause or maintain behavior • Develop interventions based on environmental conditions that cause or maintain behavior
Decide When and Where to Observe Behavior • Samples used when not practical or efficient to observe continuously • Samples provide estimates of the frequency, duration, or other dimensions of a behavior • Accuracy of estimates depends on how similar the sampled observations are to observations made at other times and in different circumstances
Time Samples • Behavior observed during selected fixed or random times believed to be representative of the behavior • Typically involves recording all instances of a behavior, but only for selected periods of time • Useful when behavior occurs at a high frequency, or observer only available at limited times • Samples can be fixed or random, but should be consistent over time
Situation Samples • Typically involves recording all instances of a behavior, but only in selected situations • Useful when behavior only occurs in a limited number of situations • Selected situations should be consistent over time
Analog Situations • Contrived situations designed to elicit representative samples of behaviors • Paper-and-pencil • Role-play • Enactment
Paper-and-Pencil Analog Client asked to respond orally or in writing to a situation presented in written form
Role-Play Client asked to visualize a situation in the natural environment and his or her response to it, or to act out situations with the practitioner or others (e.g., in group therapy) role-playing relevant people
Enactment Analog Client interacts in the agency or clinical setting with people he or she has difficulty interacting with in the natural environment
Instruments for Recording Behavior • Keep it simple, unobtrusive, likely to be used • e.g., golf score counters, pedometers, small notebooks or cards, stopwatch • Google “behavioral observation” and “smartphone” to see what’s new
Ensure Accurate Observations • Define target behaviors clearly and specifically • Select representative times and situations if samples are used • Record behavior immediately after its occurrence • Train and retrain observers
Ensure Accurate Observations (cont’d) • Monitor observers • Make observers as inconspicuous as possible to minimize reactivity • Don’t inform relevant others or independent observers of expected changes in clients’ behavior, if possible
Verifying Reliability Check interobserver reliability, if possible and practical
Reliability • Counts • smaller count / larger count • Duration • smaller duration / larger duration
Verifying Validity • Compare observations to a standard (criterion validity) • Compare observations to other measured variables, if predicted relationships
Minimizing Reactivity in Direct Observation • Observers should be as unobtrusive as possible • Observers’ presence should be explained to those being observed in simple, matter-of-fact language • Observers should follow all formal and informal rules of the observational setting
Minimizing Reactivity in Direct Observation (cont’d) • Observers should enter the setting during the least disruptive time, such as before, rather than during, a session • Observers should spend time in the setting before data collection, so that everyone is accustomed to their presence
Set Goals and Objectives • Relatively straightforward: • e.g., eliminating self-injurious thoughts and behaviors; smoking; enuresis; panic attacks; binge eating or purging; bullying, migraine headaches, truancy; theft; spousal abuse, sexual abuse, animal abuse, or other forms of violence; illegal drug use; binge drinking or other forms of excessive alcohol consumption; or driving while intoxicated
Set Goals and Objectives (cont’d) • Matter of degree and need to be more individualized: • e.g., time spent sleeping; exercising; reading or talking with children; doing homework or studying; interacting with family or friends; feeling anxious, under stress, or overwhelmed; or ruminating about some concern
Set Goals and Objectives (cont’d) • Products of behavior change: • e.g., maintaining a healthy blood glucose level or blood pressure, avoiding psychiatric hospitalization, losing or gaining weight, getting good grades, having more friends, or getting a full-time job
Advantages of Behavioral Observation • Sensitive measure of change • Avoids recall biases associated with retrospective reports • Useful for measuring outcomes with young children and others with limited verbal ability • Less subject to rater biases
Precautions in Using Behavioral Observation • Observer’s presence may produce an unrepresentative sample of behavior • Sometimes difficult to observe in the natural environment • Observation in the natural environment may be costly and impractical
