Hello Dear Colleagues,
I am here to request you. I am using a questionnaire and im not understanding an important thing in scoring of Five item physical activity questionnaire. Here im sharing the paragraph from paper attached:
To determine the physical activity level, it requires several steps. Firstly, it is necessary to obtain a score from adding their responses on the different types of physical activities, frequency, intensity, duration, and overall length of physical activity. Secondly, this was calculated by multiplying sum scores to the scaled score for the type of physical activity that the person performed. The maximum and minimum scores were “100” and “4, respectively. Thirdly, the author divided the physical activity index into five categories; “very high level”, “high level”, “acceptable level”, “low active level”, and “inactive level”. The specific cut-offs used for classification of physical activity index were “very high level (>96)”, “high level (95–64)”, “acceptable (63–36)”, “low level (35–16)”, and “inactive level (15–4)”. Higher scores indicated higher activity levels during their leisure time.
In this paragraph, i do not understand second step:
Secondly, this was calculated by multiplying sum scores to the scaled score for the type of physical activity that the person performed. The maximum and minimum scores were “100” and “4, respectively.
Kindly explain me. I have taken it from a paper (kindly see the attachment). And i am also going to attach my data excel sheet. If anyone can help with generosity, kindly apply formula there if you understand that. Kindly do me this favor. My work is stuck because of this reason. It is not difficult or long but i am not understanding "what is meant by multiplying the sum score to the scaled score for the type of physical activity.
kindly see attachment. I have calculated sum but i have left the next step.
Kindly guide me. I will be highly thankful.
Best Regards
the authors created a sum score for physical activity
the authors scaled these scores depending on the type of physical activity
the authors then multiplied these two scores.
I hope this helps.
Dear Samantha,
Thank you so much. But I still do not understand. I thought it is like:
Step-1: They added score for frequency, intensity, duration, and overall length of physical activity
Step-2: They multiply this sum score of 4 items to the score of 1st item (which is about type of activity).
Is this so?
But i am not getting if we have one total score and categorize students in 3 categories on the basis of this score. Then how can we take these three categories as 3 independent variables in AMOS for structural equation modeling.
Regards
