Table 2 Subscale names, item numbers, factor loadings, communalities, internal consistency coefficients (Cronbach's alpha), and variance explained by the first factor (%) for the individual CFPQ subscales

From: Validation of the Comprehensive Feeding Practices Questionnaire with parents of 10-to-12-year-olds

Subscale name (item numbers) Factor loadings, min-max Communalities, min-max Cronbach's alpha Variance explained by first factor

Restriction for weight (item 16, 25, 27, 31, 32, 33, 38, 42) 0.43-0.80 0.44.0.73 0.83 47%
Teaching nutrition (item 23, 29, 39) 0.45-0.81 0.20b -0.65 0.44 50%
  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.
