Hi Everyone, I have a statistical query that I wonder if you could help me with me. I have 35 participants and each participant has completed 3 questionnaires during chemotherapy and the same three questionnaires after chemotherapy. The results of the questionnaires are inputted into SPSS as scale data (calculated from adding up Likert-scale responses). One questionnaire has 5 subscales and the other two have two subscales. In order to test for a difference between questionnaire and subscale responses during and after chemo, would I carry out a PAIRED T-TEST on each participant subscale total (i.e. subscale total during chemo --> subscale total after chemo)? I am pretty sure a paired t-test is appropriate, but someone has recommended an ANOVA. However, when I attempt an ANOVA on SPSS, it doesn't seem appropriate for my data since I only have two conditions (i.e. two independent variables; during and after chemo). Saying that, they know more about stats than me! Any help would be greatly appreciated. Thank you for your help.
