Use Normal style for bulleted or numbered lists - Select this option to base list styles on the Normal paragraph style instead of the Paragraph List style.

Unless you have selected the "Use Normal style for bulleted or numbered lists" option in Word Options, Advanced category, Word applies the List Paragraph para style to each paragraph to which you apply numbering or bullet formatting. Therefore, you can affect the line spacing and spacing before/after by modifying the List Paragraph style.
