The writer, the cooperative, the student, the raters and every score are composite and illustrative; the articles cited are real.
Why Start with Questions
Kou screams and sometimes hits staff during transitions at his elementary school, a two-room building in a valley south of Missoula. Before observing him systematically, my supervisor asked me to gather indirect assessment data from the adults who know him best. Indirect assessments are questionnaires, rating scales and interviews completed by people familiar with the person. They are quick, safe and cheap, which is why they are so widely used, and they can identify the situations and consequences to examine more closely.
I used two closed-ended tools and one open-ended interview. The raters were his classroom teacher, the paraprofessional who walks him to the bus, and his grandmother, with a trained interpreter for her responses.
The Motivation Assessment Scale
Durand and Crimmins (1988) developed the Motivation Assessment Scale, a sixteen-item questionnaire in which an informant rates how often a behavior occurs in specific situations. Items are grouped into four functions: sensory, escape, attention and tangible. The function with the highest mean score is taken as the likely maintaining variable. In their original study with children who engaged in self-injury, ratings showed good reliability and predicted behavior in analog conditions.
For Kou, the teacher's ratings pointed most strongly to escape: she noted that screaming was most likely when he was asked to stop an activity. The paraprofessional's ratings pointed to tangible: she noted that he often screamed when an item he was carrying had to be left behind. His grandmother's ratings pointed to attention, because at home he screamed when she was busy with his younger cousins.
Each rater was describing a real pattern; the scale simply could not tell me which pattern mattered at school.
The Functional Analysis Screening Tool
Iwata et al. (2013) evaluated the Functional Analysis Screening Tool, a sixteen-item checklist on which informants answer yes or no to statements about the conditions surrounding a behavior. They examined agreement between pairs of informants and compared the tool's results with those of functional analyses. Agreement between informants was moderate at best, and the tool's predictions matched functional analysis outcomes in a majority of cases but far from all. The authors concluded that the tool can help structure interviews and identify conditions to test, but its results alone cannot settle what maintains a behavior.
The teacher's and paraprofessional's answers on the screening tool agreed on most items, but both answered yes to items for escape and for tangible items. That overlap was informative: it suggested that the transitions where Kou screamed might involve both ending a preferred activity and giving up a preferred item, which were the same event from two angles.
Why Informants Disagree
Several factors explain the disagreement. Informants see the behavior in different settings: his grandmother sees him at home, where the routines and people are different. They see different parts of the same event: the teacher sees the demand to stop, and the paraprofessional sees the item being taken away. They also remember behavior selectively, recalling vivid episodes rather than typical ones. And closed-ended items require informants to judge how often something happens in conditions they may never have observed separately. None of this makes the informants wrong; it makes rating scales a poor tool for deciding function.
An Open-Ended Interview
Hanley (2012) argued that closed-ended indirect tools are often less useful than an open-ended interview in which informants describe specific episodes, what happens just before, what they do afterward and what seems to stop the behavior. He suggested that such interviews can identify the combination of conditions to test in a functional analysis, including the possibility that several reinforcers operate together.
I interviewed the teacher and the paraprofessional together and his grandmother separately with the interpreter. The joint interview produced a detailed description of a typical episode. At 11:50, the class lines up for lunch in the gym, which is loud. Kou is asked to put away the toy truck he carries from the morning circle, and the paraprofessional takes his hand to walk him. He screams, drops to the floor and sometimes hits. The episode usually ends when he is allowed to carry the truck to the gym, or when the class leaves and the room goes quiet.
His grandmother described a different picture at home: screaming when she turned to his cousins, ending when she picked him up. The interpreter noted that she used a Hmong word that means both crying out and calling for someone.
Interviewing Across Languages
The interview with Kou's grandmother needed more care than the school interview. Rating scale items such as "occurs when demands are placed" do not translate cleanly, and the interpreter warned me that some items would sound like accusations of poor parenting. We dropped the rating scale for her after the first attempt and kept to the open-ended questions, asking her to tell us about the last time Kou screamed at home and what happened next. Her answers were long and specific. She described the room, who was present and what she did with her hands. That detail would have been lost in a column of numbers, and it gave the team its only picture of Kou's behavior outside school. I also learned to schedule twice as long for an interpreted interview.
Turning Data into Hypotheses
Taken together, the indirect data supported three hypotheses for testing. At school, screaming during transitions may be maintained by keeping the preferred item, by avoiding the loud gym, or by both. At home, screaming may be maintained by attention from his grandmother. The school hypotheses would be examined first, through descriptive data and then, if needed, a functional analysis with my supervisor present.
Limits and Cautions
Indirect tools have a place. They are safe, involve the people who know the student, and can be completed in an afternoon. They also give families a voice early in the process, which matters for Kou's grandmother, who had never been asked about his behavior at school. But the evidence reviewed by Iwata and colleagues shows that their results should be treated as hypotheses. The danger is a plan built on a rating scale that happens to be wrong.
Conclusion
Three informants completing the same rating scale named three different functions for Kou's screaming. Durand and Crimmins's scale and the screening tool evaluated by Iwata and colleagues both reflected real patterns but could not settle which one maintained the behavior at school. Hanley's open-ended interview identified a combined hypothesis, keeping the toy and avoiding the noisy gym, which the next units would test directly.

The Purdue Global BA430 Unit 4 instructions
In Unit 4, BA430 asks you to evaluate indirect functional assessment tools and use them with a case. Choose at least two tools, such as a rating scale and a screening checklist, and describe how each works. Report results from more than one informant, real or composite, and explain why informants may disagree. Summarize research on the reliability and validity of indirect tools. Add an open-ended interview and show how it refines the closed-ended results. End with testable hypotheses rather than a conclusion about function, and say how they will be tested. Write roughly five pages in APA style. Composite clients and informants only. Note any language needs. State which informant saw which setting.
Inside the BA430 Unit 4 example
The paper opens with three raters naming three functions for Kou's screaming. A section describes the sixteen-item rating scale and each rater's pattern, under a highlighted line that every rater described a real pattern the scale could not rank. A section summarizes Iwata and colleagues' evaluation of the screening tool and treats overlapping answers as a clue. A section explains why informants disagree. A section reports an open-ended interview with a detailed lunch-line episode, and another describes interviewing his grandmother through an interpreter. The paper ends with school and home hypotheses and the limits of indirect tools, then a conclusion naming the combined hypothesis to test next.
Where the points sit in the BA430 Unit 4 rubric
Those grading this paper look for indirect results treated as hypotheses, not as proof of function. Comparing informants and explaining their disagreement shows an understanding of the tools' limits. Accurate use of research on reliability and agreement with functional analyses earns credit. An open-ended interview that adds detail, such as a specific episode with antecedents and consequences, often distinguishes strong papers. Cultural and language considerations in interviewing families add depth. Final hypotheses should be specific enough to test in later units. Cite the rating scale's developers, the screening tool's evaluators and the interview approach in APA format, and keep every informant composite. Clear tables of each rater's scores help.
BA430 Unit 4 help from the desk
Indirect assessment papers often report the highest-scoring function from one rating scale as the answer. Others present several informants without explaining why they disagree. Students frequently overstate the reliability of rating scales or omit the research entirely. Open-ended interviews are commonly skipped in favor of checklists. Families who speak another language are sometimes interviewed through a child or not at all. Before submitting, check that your conclusion is phrased as a hypothesis and names how it will be tested. Explain each informant's vantage point. Add one detailed episode from an interview. If a family needs an interpreter, say who interpreted and why. Keep all details composite. Then cut any sentence that claims a function is proven.
