Her comments follow First Minister Nicola Sturgeon appearing to be at odds with her predecessor Alex Salmond on whether or not independence would be a key issue.
Ms Davidson also criticised the SNP over its approach to the Common Fisheries Policy and EU membership.
She said: “This has been the SNP’s week of chaos. Nicola Sturgeon made a laughing stock of herself by claiming her campaign had nothing to do with independence.
“She was forced into a U-turn after Alex Salmond popped up to say that’s all it’s about.”
