   Question

   Matthijs administered a questionnaire on depression to 100 respondents. He measured depression using 15 items, but he suspects that subscales might be present. He is testing this with a factor analysis. Part of the SPSS output is below.

   

   Would you reduce the number of factors based on the information in the output?

   
   
   1. TRUE: Yes, because only 1 item loads very high on factor 3 and the kink in the screeplot is above 2
   2. FALSE: Yes, because the factors have negative loadings and the Eigenvalues are small
   3. FALSE: No, because the explained variance with three factors is good and the pattern matrix shows 3 factors
   4. FALSE: No, because the interfactor correlations are too small to start reducing
