I have followed fourth-year university students for ten years, recording their attitudes to a particular lecture. The outcome is binary (good-bad). Can I use chi-square for trend using Crosstabs with each year in the rows and good-bad in the columns, looking at linear-by-linear association for a possible significant change in their attitudes? The number of responses vary from 60 to 90 depending on the year.

I understand this is perhaps a simple question, but being a novice I would very much appreciate your explanations nonetheless!
