Hi there,
I want to construct a scale of 'contacting government' based on the question 'Please indicate if in the past year you contacted govt about any of the following services.' --There is a list of 14 different topics. The factor analysis (result attached) shows what to me what are logical groupings of services (for instance, police and fire together, education and youth center, etc), but the Cronbach's alpha is only .592. This of course is lower than the conventionally accepted .7. I looked at the 'show alpha if item deleted' scale and nothing will increase the alpha even over .6.
Is it necessary to abandon this scale? Is there anything else I could try to make an acceptable measure? Other suggestions?
My apologies for the open ended questions. I appreciate any advice.
