[AMOS] Structural Equation Modelling
Hi there!
I was wondering whether you might be able to help me. I'm currently looking at creating a model to analyse some results from a study.
Data responses have been collected on the Pain Catastrophising Scale (PCS). A 13 item scale asking the degree to which individuals think various thoughts and feelings whilst in pain using a 5-point scale. These items are then summed to produce three subscale scores (rumination, helplessness and magnification). Higher scores indicate higher levels of catastrophizing.
I've made a model but AMOS won't run, I cannot for the LIFE of me figure out which part of the model is wrong. I've spent hours looking over it and re-drawing it to try and figure it out.
I've attached a print screen of the model so far, can anyone suggest what my problem might be preventing it from running? I've tried changing the rumination, magnification and helplessness to squares as they can become observed variables when I sum the scores for those particular subscales but that still doesn't work. I've also tried with and without error on those subscales. I've also tried changing the direction of the arrors from those subscales to the catastrophizing.....
I'm certain there is something obvious and I just can't figure it out!
