In this video I demonstrate how to obtain and use Hayes' OMEGA macro with SPSS to estimate scale reliability. This macro can be downloaded at: afhayes.com/spss-sas-and-r-macros-and-code.html
A copy of the Excel spreadsheet I use in the video can be obtained here: drive.google.com/file/d/19Ydy5E0_alQpcVyrqhyx82sYITu-Lfni/view?usp=sharing

Dear viewers: I was made aware (and have experienced myself) a few issues with using the menus interface with SPSS version 27 (the most recent version). Version 26 is what I used in this video. I was recently informed by Professor Hayes of an alternative approach to generating McDonald's omega that can be used with SPSS version 27 (or any for that matter), which can be an effective stop-gap, until the programming issue gets resolved on the drop-down menu approach. I just put together a video on a solution here: youtu.be/xscn5M5iLKQ . That video is less conceptual than the video here, so I still encourage you to watch this one for more details!
