Seven items measure how committed and emotionally attached a consumer feels toward a particular service provider, as well as their intention to recommend and remain connected to it. Nitzan and Ein-Gar (2019) used the scale in Study 5 with 282 Prolific participants. The scale appears to have been developed by the authors drawing on existing commitment and attachment measures.
