   Question

   A group of researchers want to develop an instrument that measures how traumatized children are after experiencing a car accident. Based on existing trauma literature, they created items belonging to one of the following scales: re-experiencing, avoidance, arousal, and sleep problems. Because the children themselves are too traumatized, they are taking their 36 items from 314 parents. Because the researchers expect four subscales, they conduct a factor analysis with 4 factors. Part of the SPSS output is below.

   

   How many factors do we distinguish based on the scree plot?

   
   
   1. FALSE: 1
   2. TRUE: 2
   3. FALSE: 3
   4. FALSE: 4
   
   

   Solution

   The correct answer is 2.
