The dependent measure was the number of sad words in a story continuation. For all analyses, the significance level was set at .05. Then, go through each main effect. If you had a prediction, mention it. Explain the results with respect to the prediction.
Predictions really help the reader because they structure what can be a very complicated write-up.
If you have only a few levels of the IVs, list the means in the text. If you have a really complicated analysis, consider a table of means. Structure it thusly. If the mood hypothesis were correct, then we would expect a main effect for mood. In particular, the number of sad words in the continuation should decrease from sad to happy.
