Error in Multiple Imputation PASW 17?

I have tried the Multiple imputation procedure in PASW 17 for analyzing a data set with missing values. The procedure is quite user-friendly. However, when using the procedure I discovered some strange things about the pooled results in the output. The pooled significance tests from a regression model sometimes have p-values that are exactly equal to 1. I find it hard to believe that these results are correct since the p-values of the 5 imputed datasets vary around 0.20. I can imagine that SE's increase due to the extra uncertainty because of the missing data, but I can't imagine that this p-value increases exactly to one. Thus far, I have only seen this occur within the procedure Mixed models so I don't know if it occurs in other procedures as well. For people who want to see what I mean, I can send the data and the syntax file that generated these results, on request.

Best regards,

Joost van Ginkel
