The introduction of smartphones has enhanced communication, creating a phenomenon known as nomophobia, which is characterised by the fear of being without mobile phone access. "Nomophobic Behavioural Identification Scale” was developed to investigate nomophobia and measure the anxieties among mobile phone users. This tool comprises 24 items and was tested on 110 randomly selected students. Validity was assessed using correlation methods, while reliability was established with a Cronbach's alpha of 0.834, indicating strong internal consistency. The scale measures nomophobia on a range from 20 to 115, where higher scores reflect greater levels of nomophobia.
