Guest guest Posted June 24, 2003 Report Share Posted June 24, 2003 Hey guys it's Jenn. I was fortunate enough to go on Friday to Dr. Iwata's presentation " Aggressive and Self-Injurious Behaviors- Assessment and Treatment " . ELIJA, thank you so much for the opportunity to learn from Dr. Iwata, he was just phenomenal! I never thought I could learn so much in one day, this WAS NOT a workshop to miss. This honestly is really a tough one to go over just because it is such a serious subject and the presentation was so detailed and every detail was so vital that trying to summarize it is almost impossible (not to mention Dr. Iwata urged us to go to the source-his list of references in the handout-to appropriately learn about the material he discussed with us, so if the most published author in the Journal of Applied Behavior Analysis thinks he is watered down, my notes here are REALLY far removed!) My son currently does not have any SIB or aggressive behaviors but what we learned could be applied to analyzing even stereotypic/repetitive behaviors, also having an understanding of why learning occurs ( " assumption that behavior problems are a learned phenomena " ) may help to reduce the chances of any of these behaviors being learned. What I hope to pass on to parents from my notes and Dr. Iwata's handout is a little insight on 3 methods for conducting functional analyses (purpose= " to identify what it is about the environment and Identify the variables of which behavior is a function; discover 'cause-effect' relationship " goals= understanding, treatment, and prevention) I know of a few parents that had really wanted to go to this and couldn't so here's about half of what was discussed: Dr. Iwata talked to us about why learning occurs: 1. Positive Reinforcement ( " social positive reinforcement " -attention, access to tangible materials; " automatic positive reinforcement " - sensory stimulation) 2. Negative (removal) Reinforcement ( " social negative reinforcement " - escape form demands; " automatic negative reinforcement " - pain attention) (isn't that amazing that all the behaviors ultimately boil down to these four functions?-social positive, automatic positive; social negative, automatic negative--crazy!) Through positive and negative reinforcement (except in the case of Lesch Nyan (?) Syndrome where SIB occurs as a result of a genetic disorder) inappropriate behaviors, aggression, and SIB's may have been inadvertently shaped from non-compliance (ex. given on " social negative(removal) reinforcement " ask child to point to a cup, the learner doesn't respond (non-compliance) so you prompt the child and ask point to the cup and the child now knocks everything off the table (non-compliance now shaped into destructive behavior) you put the cup back ask the child point to the cup the learner bites the teacher or hits their head on the table so you tend to the child or your injury and terminate the session (non-compliance shaped into destructive behavior shaped into aggression or SIB , the aggression or SIB has now been reinforced through " social negative reinforcement " The child has learned that to get out of a task I just have to " make someone bleed " as Dr. Iwata put it, I know that's not funny but it really was when he said it) Dr. Iwata went over (once again in great detail-and in plain english ;0) -each step below) methods for conducting functional analyses: (from hand out) 1.. ANECDOTAL (indirect methods)- GENERAL CHARACTERISTICS: *focus on circumstances under which behavior occurs * based on informant recall* *data consists of verbal report (interview, checklist, rating scale)* STRENGTHS: a. relative ease of implementation-little time and training required for administration b. does not involve risk to client c. structured method for gathering interview data d. potentially useful as initial guide to assessment LIMITATIONS: a. highly subjective data b. poor reliability and questionable validity c. insufficient for treatment development. SUGGESTIONS FOR IMPLEMENTATION: a. use as a preliminary guide only b. use multiple, relevant informants c. follow-up with direct observation (Dr. Iwata explained how this assessment is JUST A LITTLE BETTER THAN DOING NOTHING!; this type of assessment would not hold up in court but could be helpful in narrowing down the establishing operation that is maintaining the behavior) 2.. DESCRIPTIVE (naturalistic) ANALYSIS -GENERAL CHARACTERISTICS: *direct observation of circumstances under which behavior occurs* *usually conducted under naturalistic conditions in relevant contexts* *data consist of narrative, frequency, or conditional probability* PROCEDURAL VARIATIONS: scatter plot, ABC analysis, Interval and time sampling STRENGTHS:a. more reliable than indirect methods b. objective and (usually) quantitative data c. behavior sampled in relevant settings d. identifies correlational relationships e. may be sufficient for treatment development LIMITATIONS: a. often uninterpretable b. potential risk to individual c. complexity and time requirements d. may not identify effects of intermittent schedules e. irrelevant variables may mask relevant ones (try to sort relevant from irrelevant, what happens the most isn't always the most relevant!) f. caregivers may artificially suppress problem behavior, thereby masking relevant variables g. correlational relationships not equal to functional relationships SUGGESTIONS FOR IMPLEMENTATION: a. objective definitions of behavior and context b. measurement scale sensitive to changes in behavior c. adequate sampling of activities, settings, etc. d. use of repeated observation 3.. FUNCTIONAL (experimental) ANALYSIS-GENERAL CHARACTERISTICS: *direct and quantitative observation of behavior *conditions of observation are controlled *comparison between at least one test and one control condition* PROCEDURAL VARIATIONS: a. single v. multiple variable assessment b. antecedent and/or consequence manipulations c. design (multielment, reversal, combined) d. length of assessment (behavior or time referenced) e. data analysis STRENGTHS: provides clear demonstration of a functional relationship b. high degreee of environment control (can isolate multiple, intermittent, or subtle variables) c. suggests short-term strategies for behavior management d. provides clear basis for treatment development LIMITATIONS: potential risk to individual b. complexity and time requirements c. requires control over assessment context d. may not reveal all relevant environmental correlates SUGGESTIONS FOR IMPLEMENTATION: a. conduct risk assessment b. obtain informed consent c. gather preliminary assessment information (my note--utilizing INDIRECT and DESCRIPTIVE analysis) d. make conditions highly discriminable e. begin with an " easy " case f. videotape sessions for training and to monitor procedural fidelity Number 3., Functional Analysis is the most precise and flexible although also the most complex. Problem behavior maintained by automatic negative reinforcement (pain attention) cannot be assessed (since it is usually a medical condition, discomfort, etc. ex. headache) some treatment options include: alleviate the condition (noncontingent reinforcement) ,pain reduction, behavioral replacement (establish alternative pain reduction response) ****REINFORCEMENT-BASED APPROACHES TO BEHAVIOR REDUCTION**** *eliminate the behavior's establishing operation (deprivation or aversive stimulation)* --noncontingent reinforcement NCR *eliminate the behavior's maintaining contingency* --extinction EXT (planned ignoring) ~(see note at bottom of this post please)~ *replace the behavior with an alternative response* --Differential reinforcement ***TREATMENT PROTOCOLS FOR BEHAVIOR PROBLEMS MAINTAINED BY ATTENTION*** --Noncontingent Reinforcement (NCR rationale: the purpose of this procedure is to decrease problem behavior by providing free access to reinforcers on a scheduled basis) --Extinction (EXT rationale: the purpose of this procedure is to decrease problem behavior maintained by social reinforcement (ie attention, access to preferred items, etc) --Functional Communication Training (rationale: the purpose of this procecdure is to teach an alternative response to gain access to positive reinforcement) **TREATMENT PROTOCOLS FOR BEHAVIOR PROBLEMS MAINTAINED BY ESCAPE** --Compliance Training (with extinction and behavioral momentum components. Rationale: the purpose of this procedure is to reduce problem behavior maintained by escape and to increase compliance --Functional Communication Training: escape from instructions/tasks (with extinction) Rationale: the purpose of this procedure is to teach an alternative escape response **TREATMENT PROTOCOLS FOR BEHAVIOR PROBLEMS MAINTAINED BY AUTOMATIC REINFORCEMENT** --Noncontingent Reinforcement: Access to alternative reinforcers (rationale: the purpose of this procedure is to decrease problem behavior by providing free access to alternative activities that directly produce their own reinforcers --Sensory Extinction: rationale- the purpose of this procedure is to decrease problem behavior by attenuating reinforcement directly produced by the response --Differential Reinforcement of Alternative Behavior (DRA): Strengthening leisure item manipulation (Rationale: the purpose of this procedure is to teach alternative responses that directly produce their own reinforcers. It should be used with individuals who engage in little or no independent object manipulation~ie individuals for whom noncontingent access to leisure items produces no therapeutic effect) As you can see this conference was PACKED with vital information. What I've provided above is a very chopped up version and only part of what was presented to us by Dr. Iwata. Obviously if you are in a situation where aggression and SIB is occurring you will first provide protection from harm to you and the learner and to contact the proper professionals for assessment and treatment but I hope these notes will help parents get a little insight on what it is the professionals are doing or if they are doing enough (not just restraining and medicating, not saying anyone says that's all they do and there may be situations where that is appropriate, but I wonder if ABA is utilized enough. I know in dealing with my pediatrician in the past she always suggests medication before considering ABA, I understand she's only trying to help) Again, just an amazing day. Thank you so much for that rare opportunity. take care, Jennica EXTINCTION: I think it's really important to note that when you use extinction (planned ignoring,--sounds so simple that way doesn't it?) keep in mind that the behavior you are ignoring is going to increase in magnitude, frequency, and variation (Extinction Burst) so it is critical to be VERY careful when you are using extinction, consider all the variations of the behavior and make sure you CAN follow through (otherwise you may accidentally reinforce a behavior that is MUCH WORSE than the one you are trying to get rid of now), there are situations where an extinction procedure IS NOT an option.
