Likert items are rarely very discrepant from interval level of measurement.

Do you know or do you have a guess why some items have missing values?

How was the questionnaire administered?  You may want to consider how to improve the quality of administration in future work.

If you scatterplot the results of the two approaches in my reply to your other post what do you see?

Are the scales from previous work that established the psychometric qualities of the scales?  OR Did you write the scale items your self specifically for this study?

Recall that a scale can be considered a summary of several imperfect repeated measures of a construct that is used as representing what is common to the set of items.  The summary is considered more representative of the underlying construct.
