Active Coping: Interdisciplinary Program for Chronic Pain, Physiotherapy Unit (Spain)

The SF-36 measures health-related quality of life across 8 dimensions: physical function, role limitations due to physical health, bodily pain, general health, vitality, social functioning, role limitations due to emotional problems, and mental health. Scores range from 0 to 100, where 0 indicates the worst possible health state and 100 indicates the best possible health state.

The Roland-Morris Disability Questionnaire assesses the degree of functional disability caused by back pain in daily life. Scores range from 0 to 24, where 0 indicates no disability and 24 indicates the maximum level of disability.

The SPPB evaluates three aspects of physical mobility: balance, gait speed, and lower limb strength (chair stand test). Total scores range from 0 to 12, where 0 indicates the worst physical performance and 12 indicates the best physical performance.

The TUG measures the time in seconds required to stand up from a chair, walk 3 metres, return, and sit down. Scores above 13.5 seconds indicate risk of falls; below 10 seconds indicates unrestricted mobility.

The 30-second sit-to-stand test records the number of times a participant can stand from a chair without using their arms in 30 seconds. Fewer than 8 repetitions indicates fall risk. Higher scores indicate better lower limb strength and balance.

The 6-Minute Walk Test records the total distance in metres walked in 6 minutes, with perceived exertion assessed using the Modified Borg Scale ranging from 0 (no exertion at all) to 10 (maximum exertion). Greater distance indicates better exercise tolerance.

The TSK-11SV assesses fear of movement and re-injury in people with chronic pain. Scores range from 11 to 44, where higher scores indicate greater kinesiophobia

The ECD assesses the tendency to magnify, ruminate, and feel helpless in response to pain across 13 items. Scores range from 0 to 52, where higher scores indicate greater pain catastrophizing.

The CSI assesses the presence and intensity of somatic and emotional symptoms associated with Central Sensitization Syndrome across 25 items. Scores range from 0 to 100, where higher scores indicate greater central sensitization symptom burden.

Medication use is recorded through a structured registry covering oral analgesics (paracetamol, minor and major opioids, antimigraine drugs), co-adjuvant drugs (corticosteroids, anticonvulsants, anxiolytics, antidepressants), and topical analgesics. Change is assessed as the presence, type, and dose per 24 hours of each medication category at each timepoint.

Number of Primary Care consultations (both medical and physiotherapy) recorded per participant during the study period, extracted from clinical records. Higher consultation frequency indicates greater healthcare resource utilization.

The STAI assesses anxiety in two dimensions: state anxiety (momentary) and trait anxiety (stable predisposition), each scored across 20 items. Scores for each subscale range from 20 to 80, where higher scores indicate greater anxiety.

The BDI-II evaluates the severity of depressive symptoms across 21 items covering cognitive, affective, and somatic domains. Scores range from 0 to 63, where 0-13 indicates minimal depression, 14-19 mild depression, 20-28 moderate depression, and 29-63 severe depression.

The PSQI assesses subjective sleep quality and disturbances over the past month across 7 components including sleep latency, duration, efficiency, and daytime dysfunction. Global scores range from 0 to 21, where scores above 5 indicate poor sleep quality.

A 10-item true/false/unsure survey assessing knowledge of chronic pain neuroscience concepts, including the relationship between pain and tissue damage, central sensitization, and active coping strategies. Higher correct response rates indicate greater pain neuroscience knowledge.
