AMOS Query

[Kollipara, Kiran]

Hi All,

 

One of our sales consultants have a pre sale query about functionality of AMOS, I have been pointed to this email address to get some help, please suggest where can I get some information about this below query.

 

 

 

Query :--

 

 

I would like to ask about whether AMOS has a certain functionality to help me decide if the program is appropriate for my research.

 

I am investigating the structure of emotional responses over time, based on self-ratings provided by respondents on 16 items, measured at 4 time points (i.e. 64 ratings per respondent). I expect to conduct several confirmatory factor analysis (CFA) models to test for potential structures of these responses. More specifically, I want to conduct multi-level CFAs to assess both between-person and within-person variation in scores. I have been informed this is possible with AMOS.

 

However, my question is whether AMOS has the functionality to also control for auto-correlations that may be present in such repeated measures data? That is, I expect stronger correlations between responses at:

 

Time 1 <--> Time 2

Time 2 <--> Time 3

Time 3 <--> Time 4

 

Responses given closely in time would reasonably be correlated. And I'd expect weaker correlations between responses at other times (e.g. Time 1 <--> Time 4). Can AMOS account for this auto-correlated data structure? If so, how could I find out how to enable this in AMOS?
