“…Self-report questionnaires are the most common method for collecting information about pain, and pain intensity is the most common domain assessed by clinicians and researchers (Jensen, 2011). Pain intensity measures that have been used in youths with physical disabilities include the Wong-Baker FACES Pain Rating Scale (FACES) (e.g., Ramchandren et al , 2014; Tüzün et al , 2010), the 0 – 10 Numerical Rating Scale (NRS-11) (e.g., Jóźwiak et al , 2011; Suokas et al , 2012; Tieleman et al , 2011), and the Visual Analogue Scale (VAS) (e.g., Vles et al , 2008; Wen et al , 2013). Another straightforward option for assessing pain intensity is the (categorical) Verbal Rating Scale (VRS), which asks the respondent to select the word or phrase from a list (e.g., None, Mild, Moderate, Severe) that best represents his or her pain intensity level (Jensen & Karoly, 2011).…”
