Hi Kamal,

You can perform a Cronbach's alpha on dichotomous variables.

There are many similar topics in ResearchGate that might help you.

Best regards,

Julian

Z. A. Al-Hemyari

Dear Kamal,

The Cronbach's Alpha/ item reliability can be used for responses scales using Likert ratings as well as those using binary (yes-no or 1-2) answers formats.

Regards.
