  1. a Item 20 on the Environment subscale did not load onto its assigned scale, but had a high loading onto a second factor.
  2. b The following items had very low communalities: item 10 on the child control subscale, item 41 on the Modeling subscale, and item 39 on the Teaching nutrition subscale.
