development of a computer adaptive physical function instrument for social security administration disability determination
Archives of Physical Medicine and Rehabilitation, 2013Co-Authors: Pengsheng Ni, Christine M Mcdonough, Alan M Jette, Kara Bogusz, Elizabeth E Marfeo, Elizabeth K Rasch, Diane E Brandt, Mark Meterko, Stephen M HaleyAbstract:Abstract Objectives To develop and test an instrument to assess physical function for Social Security Administration (SSA) disability programs, the SSA-Physical Function (SSA-PF) instrument. Item response theory (IRT) analyses were used to (1) create a calibrated item bank for each of the factors identified in prior factor analyses, (2) assess the fit of the items within each scale, (3) develop separate computer-adaptive testing (CAT) instruments for each scale, and (4) conduct initial psychometric testing. Design Cross-sectional data collection; IRT analyses; CAT simulation. Setting Telephone and Internet survey. Participants Two samples: SSA claimants (n=1017) and adults from the U.S. general population (n=999). Interventions None. Main Outcome Measures Model fit statistics, correlation, and reliability coefficients. Results IRT analyses resulted in 5 unidimensional SSA-PF scales: Changing & Maintaining Body Position, Whole Body Mobility, Upper Body Function, Upper Extremity Fine Motor, and Wheelchair Mobility for a total of 102 items. High CAT accuracy was demonstrated by strong correlations between simulated CAT scores and those from the full item banks. On comparing the simulated CATs with the full item banks, very little loss of reliability or precision was noted, except at the lower and upper ranges of each scale. No difference in response patterns by age or sex was noted. The distributions of claimant scores were shifted to the lower end of each scale compared with those of a sample of U.S. adults. Conclusions The SSA-PF instrument contributes important new methodology for measuring the physical function of adults applying to the SSA disability programs. Initial evaluation revealed that the SSA-PF instrument achieved considerable breadth of coverage in each Content Domain and demonstrated noteworthy psychometric properties.

food allergy knowledge attitudes and beliefs of parents with food allergic children in the united states
Pediatric Allergy and Immunology, 2010Co-Authors: R Gupta, Elizabeth E Springston, Jennifer S Kim, Bridget Smith, Jacqueline A Pongracic, Xiaobin Wang, Jane L HollAbstract:Gupta RS, Springston EE, Smith B, Kim JS, Pongracic JA, Wang X, Holl J. Food allergy knowledge, attitudes, and beliefs of parents with food-allergic children in the United States. Pediatr Allergy Immunol 2010: 21: 927–934. © 2010 John Wiley & Sons A/S Parents of food-allergic children are responsible for risk assessment and management of their child’s condition. Such practices are likely informed by parental knowledge, attitudes, and beliefs of food allergy. Our objective was to characterize food allergy knowledge and perceptions among parents with food-allergic children. Parents were recruited nationally between January 2008 and 2009 to complete the validated, web-based Chicago Food Allergy Research Survey for Parents of Children with Food Allergy. Findings were analyzed to provide composite/itemized knowledge scores, describe attitudes and beliefs, and examine the effects of participant characteristics on response. A sample of 2945 parents was obtained. Participants had an average knowledge score of 75% correct (range 19–100%). Strengths were observed in each Content Domain; e.g., 95% of participants accurately identified the signs of a milk-induced reaction. Weaknesses were limited to items assessing food allergy triggers/environmental risks and perceptions of susceptibility/prevalence; e.g., 52% of parents incorrectly believed young children are at higher risk for fatal anaphylaxis than adolescents. Parental attitudes/beliefs were diverse, although 85% agreed children should carry an EpiPen at school and 91% felt schools should have staff trained in food allergy. One in four parents reported food allergy caused a strain on their marriage/relationship, and 40% reported experiencing hostility from other parents when trying to accommodate their child’s food allergy. In conclusion, parents in our study exhibited solid baseline knowledge although several important misconceptions were identified. While a broad spectrum of parental perceptions was observed, a large proportion of parents reported that their child’s food allergy had an adverse impact on personal relationships and also agreed on certain policies to address food allergy in schools.

food allergy knowledge attitudes and beliefs of primary care physicians
Pediatrics, 2010Co-Authors: R Gupta, Elizabeth E Springston, Jennifer S Kim, Bridget Smith, Jacqueline A Pongracic, Xiaobin Wang, Jane L HollAbstract:Objective To provide insight into food allergy knowledge and perceptions among pediatricians and family physicians in the United States. Methods A national sample of pediatricians and family physicians was recruited between April and July 2008 to complete the validated, Web-based Chicago Food Allergy Research Survey for Primary Care Physicians. Findings were analyzed to provide composite/itemized knowledge scores, describe attitudes and beliefs, and examine the effects of participant characteristics on response. Results The sample included 407 primary care physicians; 99% of the respondents reported providing care for food-allergic patients. Participants answered 61% of knowledge-based items correctly. Strengths and weaknesses were identified in each Content Domain evaluated by the survey. For example, 80% of physicians surveyed knew that the flu vaccine is unsafe for egg-allergic children, 90% recognized that the number of food-allergic children is increasing in the United States, and 80% were aware that there is no cure for food allergy. However, only 24% knew that oral food challenges may be used in the diagnosis of food allergy, 12% correctly rejected that chronic nasal problems are not symptom of food allergy, and 23% recognized that yogurts/cheeses from milk are unsafe for children with immunoglobulin E-mediated milk allergies. Fewer than 30% of the participants felt comfortable interpreting laboratory tests to diagnose food allergy or felt adequately prepared by their medical training to care for food-allergic children. Conclusions Knowledge of food allergy among primary care physicians was fair. Opportunities for improvement exist, as acknowledged by participants' own perceptions of their clinical abilities in the management of food allergy.
