Assessing fear of movement in kids with chronic pain just got a little easier. Researchers have validated a shortened 7-item version of the Tampa Scale of Kinesiophobia for Youth (TSK-7-Y), finding it performs on par with the original 11-item tool — without the extra questionnaire fatigue. The study, published in Pain, analyzed data from 1,252 children and adolescents aged 8–19 across three pediatric medical centers.

The TSK-7-Y captures two key dimensions: Bodily Threat Beliefs and Fear of Movement. Its predictive validity held up well against established measures of pain catastrophizing, functional disability, depression, and mobility — nearly matching the longer version across the board.

By the Numbers:

• 1,252 pediatric patients included (mean age 14.6 years; 79.2% girls)
• TSK-7-Y correlation with pain catastrophizing: r=0.51 vs. r=0.54 for TSK-11
• TSK-7-Y correlation with functional disability: r=0.35 vs. r=0.33 for TSK-11
• Rasch item difficulty values ranged from -0.65 to 0.91 logits

Why it matters: Fear of movement is a key psychological barrier in pediatric chronic pain management. A shorter, validated tool means clinicians can screen more efficiently — especially in busy clinical settings — without sacrificing the quality of assessment needed to guide treatment.
