Hi,
I am here to ask a question that can we use different scales for SEM in AMOS.
I am here to request you if you have seen any article using 3-point likert scale for SEM in AMOS,, kindly refer me to that. I am not finding any paper where 3-point likert has been used. I will be highly grateful to you.
Further, I have another problem. I am using International physical activity questionnaire for assessing physical activity (IPAQ) of students. According to scoring protocol, i can also use categorical score.
But I want to use 3 factors of IPAQ (Vigorous, moderate, walking) as separate independent variables. Now the problem is when we use IPAQ categorical scale, it gives only one single item (see attachment) which tells us about level of high, medium and low physical activity. But there is no criteria upon how much time is prescribed to low, medium and vigorous PA and so is for others. But I want to use it as high, medium and low level of all the three factors having 3 modes for each:
Vigorous: high, medium, low
Moderate: High, medium, low
Walking: high, medium, low
So, I am confused how can i rate them on 3-point Likert scale this way if there is no criteria to specify how three factors can have 3 modes.
and one more thing is that how continuous data can be used in AMOS. if i want to use continuous score of IPAQ, can I do analysis in AMOS? Kindly answer with reference.
I will be highly grateful to you.
Best Regards
