Brief Summary

The goal of this observational study is to learn whether pain in the temporomandibular joint is associated with pelvic pain in adults, and to explore psychosocial and pain sensitization factors that may contribute to both conditions. The main questions it aims to answer are: Is temporomandibular joint dysfunction associated with pelvic pain in the adult population? Are psychosocial factors and indicators of central pain sensitization related to the co-occurrence of these pain conditions? Participants will complete standardized, self-administered questionnaires at a single point in time that assess: Temporomandibular joint symptoms Pelvic pain symptoms Psychosocial factors and pain sensitization features No treatments or interventions will be given as part of this study.

Outcome Measures

Primary Outcomes (1)

• Co-occurrence of Chronic Pain Conditions

  The presence and degree of overlapping chronic pain conditions will be assessed using the Chronic Overlapping Pain Conditions Screener (COPC-S). This validated tool identifies co-occurring pain conditions across different body regions and will be used to classify participants into pain groups and to quantify overlap between temporomandibular and pelvic pain.

  Baseline

Secondary Outcomes (6)

• Pain Intensity

• Kinesiophobia Related to Temporomandibular Pain

Study Arms (4)

Chronic Pain

Adults with chronic pain who do not report pain in the pelvic region or the temporomandibular joint.

Temporomandibular Pain Only

Adults with chronic pain who report pain or dysfunction in the temporomandibular joint region but do not report pelvic pain.

Pelvic Pain Only

Adults with chronic pain who report pelvic pain but do not report temporomandibular joint pain.

Overlapping Pelvic and Temporomandibular Pain

Adults with chronic pain who report both pelvic pain and temporomandibular joint pain, consistent with chronic overlapping pain conditions.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Study participants will be selected from the adult general population experiencing chronic pain. The study population includes individuals aged 18 years or older who report pain in the orofacial (temporomandibular) region, the pelvic region, both regions, or chronic pain in other body areas without involvement of the temporomandibular or pelvic regions. Participants must be able to read and understand Spanish and provide informed consent.

You may qualify if:

• Age 18 years or older.
• Presence of chronic pain
• Ability to complete self-administered questionnaires.
• Signed informed consent provided prior to participation.

You may not qualify if:

• Inability to read or understand Spanish.
• Failure or refusal to provide informed consent for participation in the study.
