I am very much concerned with following;
Cronbach's reliability test > .7
Correlation among variables >0.2-0.8
Basically I am using variables from two base articles to compile a new adapted questionnaire. What preventive measures should i use to refrain from negative Cronbach's alpha or BELOW 0.7 test results. Also, Correlation matrix exhibit either weak or moderate correlation among all variables.
Is there a software that can help me factor by factor analysis to develop a new questionnaire based on previous research, etc.
Please help, all of you PhD doctors.
Currently I am working on this file, it has almost 80 observations. Cronbach;s alpha is 0.42.
Through the confirmatory factorial analysis you can determine the indicators of the factors with factorial loads greater than .40, also I recommend to realize McDonald's omega reliability that takes into account the correlations of the variables for what it estimates with better precision, these must be greater than .70. You can perform through statistical software such as JAMOVI or JASP, the latter includes SEM analysis that allows you to estimate more accurately your factor analysis because it estimates the measure of error.
Any combining of questionnaires should proceed with comprehensive construct validation procedures.
Hope this helps
Matt
