title: Short-Form Audit Instrument for Assessing Corner Store Healthfulness.
abstract: To develop a valid and feasible short-form corner store audit tool (SCAT) that could be used in-store or over the phone to capture the healthfulness of corner stores.
  
  
  
  Nonexperimental.
  
  
  
  Four New Jersey cities.
  
  
  
  Random selection of 229 and 96 corner stores in rounds 1 and 2, respectively.
  
  
  
  An adapted version of the Nutrition Environment Measures Survey for Corner Stores (NEMS-CS) was used to conduct in-store audits. The 7-item SCAT was developed and used for round 2 phone audits.
  
  
  
  Exploratory factor analysis and item response theory were used to develop the SCAT.
  
  
  
  The SCAT was highly correlated with the adapted NEMS-CS ( r = .79). Short-form corner store audit tool scores placed stores in the same healthfulness categories as did the adapted NEMS-CS in 88% of the cases. Phone response matches indicated that store owners did not distinguish between 2% and low-fat milk and tended to round up the fruit and vegetable count to 5 if they had fewer varieties.
  
  
  
  The SCAT discriminates between higher versus lower healthfulness scores of corner stores and is feasible for use as a phone audit tool.
