Prior to hypothesis testing, a multivariate outlier was detected
using Mahalanobis distance with p < .001 (i.e., an outlier value of
39.94; see Tabachnick & Fidell, 2007). As inclusion of this outlier
changed the pattern of results substantially, this case was excluded
from the analyses. The means, standard deviations, and correlations
for the study’s variables are reported in Table 1. Significant
moderate correlations were found among the extended TPB
predictors. As expected, all extended TPB predictors were
significantly correlated with intention and behaviour. At Time 2
follow-up, the average self-rated level consumption of foods low in
saturated fats was 5.91 (SD = 1.45), reflecting a fairly high level of
consumption of foods low in saturated fats during the previous
week.
