A single face-to-face group session of approximately 60-80 minutes provided through active participation. Five key domains will be structured from the Fear and Belief Avoidance Questionnaire that will serve as a guide for the sessions through a Powerpoint presentation. In addition, participants will be encouraged to be active by walking for 20-30 minutes 3-5 times a week and will be taught an exercise to improve transverse abdominis activation (abdominal corset or follow-through).

With the main ones, a brochure will be delivered and informative capsules will be made to which the participants will have access (5 videos of 15 minutes, one per domain). Participants will be instructed to record on a calendar the days they read the brochure and/or reviewed the information capsules to assess treatment compliance and for each domain invent a metaphor or script for how they would explain it to another person. This activity must be delivered in the second evaluation.

A pain neuroscience education session geared towards fear-avoidance beliefs

The Fear Avoidance Beliefs Questionnaire consists of two subscales: (1) a 7-item work subscale (FABQ-W) and (2) a 4-item physical activity subscale (FABQ-P). Both subscales score on a Likert-type scale from 0 to 6 points on each item. Higher scores indicate higher levels of fear-avoidance beliefs.

An algometer will be used to measure pressure pain sensitivity (SPD), which is defined as the amount of applied pressure required for a subject to report the onset of pain sensation. It will be applied three times for each moment of evaluation and the average of the three applications will be considered. The unit of measure kg/cm2/s will be used.

Cain self-efficacy questionnaire (PSEQ) consists of 10 items rated on a 7-point Likert scale from 0 ("not at all sure") to 6 ("very sure"). Higher scores indicate stronger self-efficacy beliefs, while low scores indicate a subject more focused on their pain.

participants were assigned to the lower educational level if they had not completed secondary education and to the higher educational level if they had completed secondary education or university studies
