A, 29-question, patient-reported survey measuring health-related quality of life across seven core domains: physical function, fatigue, pain interference, depression, anxiety, sleep disturbance, and social roles. Developed by the NIH, it includes a 0-10 pain intensity item and four questions per domain. Scores are transformed in a T-score with a mean of 50 and a standard deviation of 10, based on a reference population (typically the U.S. general population or a specific clinical group). A T-score above 50 indicates a better outcome than average.

A 5-item clinical tool designed to assess physical activity among populations at high risk of sedentary behaviour.T he Simple Physical Activity Questionnaire (SIMPAQ) is scored by calculating the average daily time (in hours or minutes) spent on five categories over the past week: time in bed, sedentary behavior, walking, structured exercise, and incidental activity. These five components should sum to approximately 24 hours per day, which provides a check for reporting accuracy. Time spent on physical activity is calculated by summing walking and structured exercise. The lowest score is 0 hours and the highest 24 hours. Higher scores means more time spent exercising.

This scale assesses people's motivation for engaging in their leisure activities. It assesses 7 types of motivation : intrinsic motivation toward knowledge, accomplishment and stimulation, as well as external, introjected and identified regulations and amotivation. It contains 28 items (4 items for each of the 7 sub-scales) assessed on a 7-point scale. Scores for each subscale are summed to determine which motivations (e.g., intellectual, social, competence, stimulus-avoidance) drive the behavior (ranging from 4 to 28 points). The highest scoring subscale identifies the primary reason for a person's engagement in leisure activities.

A 14-item, self-report screening tool (7 questions for anxiety, 7 for depression) used to detect emotional distress in patients with physical health conditions. It is scored by summing responses to the 14 items , each rated 0-3. Subscales (HADS-A and HADS-D) range from 0 to 21. Scores of 0-7 are normal, 8-10 mild, 11-14 moderate, and 15-21 severe. Higher scores indicate higher distress.

A self-administered questionnaire that measures a patient's functional disability caused by low back pain. It consists of 10 items assessing daily activities (e.g., pain, lifting, walking), with scores from 0-100% representing disability levels from minimal to bedbound.
