A Comparison of Descriptive and Functional Analyses of Inappropriate Mealtime Behavior.

In recent years, rather than being used to assess the potential function of a response, descriptive assessment methods have been applied to evaluate potential consequences or contingencies for problem behavior (Borrero, Woods, Borrero, Masler, & Lesser in Journal of Applied Behavior Analysis, 43, 71-88. doi: 10.1901/jaba.2010.43-71, 2010) or to assist with designing baseline conditions to approximate caregiver behavior (Casey et al. in Behavior Modification, 33, 537-558. doi: 10.1177/0145445509341457, 2009). It has been shown that descriptive assessments of some forms of problem behavior (e.g., self-injury, aggression) are not good indicators of behavioral function and should not be used exclusively when conducting functional behavior assessments (Thompson & Iwata in Journal of Applied Behavior Analysis, 40, 333-338. doi: 10.1901/jaba.2007.56.06/epdf, 2007). However, the extent to which descriptive assessments of inappropriate mealtime behavior can predict behavioral function is not yet clear. We conducted descriptive assessments of inappropriate mealtime behavior and compared the results to functional analyses for ten children with severe food refusal. Results showed that, for 71 % of participants, the descriptive and functional analyses matched. These results suggest that the correspondence between descriptive and functional analyses, at least for inappropriate mealtime behavior, may be higher than that for other forms of problem behavior.

Descriptive analyses of pediatric food refusal and acceptance.

Functional analyses of inappropriate mealtime behavior typically include conditions to determine if the contingent delivery of attention, tangible items, or escape reinforce food refusal. In the current investigation, descriptive analyses were conducted for 25 children who had been admitted to a program for the assessment and treatment of food refusal to determine if the consequences commonly delivered during functional analyses were observed during parent-conducted meals. The conditional probabilities for the delivery of attention, tangible items, and escape following food refusal and acceptance were compared to the unconditional probabilities of each event. Results showed that attention and escape most frequently followed refusal and differed depending on the topography of refusal. Implications for further evaluations of food refusal using similar methods are discussed.

Descriptive analyses of pediatric food refusal: the structure of parental attention.

Mealtime observations were conducted and occurrences of appropriate and inappropriate mealtime behavior and various forms of parental attention (e.g., coaxing, reprimands) were recorded for 25 children admitted to an intensive feeding program and their parents. Using the data from the observations, lag sequential analyses were conducted to identify changes in the probability of child appropriate and inappropriate mealtime behavior before and after various forms of parental attention. A combination of univariate and repeated measures ANOVAs using frequency of child behavior were also conducted to corroborate conclusions drawn from the visual analysis of individual participant data. Results showed that parental attention was frequently followed by temporary decreases in inappropriate mealtime behavior and increases in bite acceptance. Moreover, various forms of parental attention resulted in statistically significant changes in child behavior, which supports the clinical utility of these data.
