The modified Stroop paradigm as a measure of selective attention towards pain-related information in patients with chronic low back pain.
The present study assessed, by means of a modified Stroop paradigm, whether highly fearful patients with chronic low back pain pay selective attention to words related to movement and injury. Two groups of patients (High Fear and Low Fear) were included based on their scores on the Tampa Scale of Kinesiophobia (TSK), a measure of fear of movement or (re)injury. A control group was recruited by means of advertisement in a local newspaper. Repeated-measures analysis of variance was conducted to examine whether highly fearful pain patients pay more selective attention to movement and injury words, compared to patients with low pain-related fear and controls. The results from the present study do not support the proposition that highly fearful patients with chronic low back pain selectively pay attention to words related to injury and movement. Limitations of the modified Stroop paradigm are discussed as well as the need for the application of alternative methods such as the dot-probe paradigm.
