This study aims to explore the relationships between knowledge about pain, coping strategies, and sexual function in adults with chronic pelvic pain. Chronic pelvic pain is a persistent condition that can affect physical health, emotional wellbeing, and daily life. Research suggests that understanding of pain and coping responses may influence how people experience chronic pain and its impact on quality of life.

Participants will be adults diagnosed with chronic pelvic pain who attend hospital outpatient clinics. Those who agree to participate will complete a set of questionnaires assessing knowledge about pain, coping strategies, sexual function, and basic demographic and pain-related information. Participation is voluntary and anonymous and involves a single assessment session lasting approximately 10-15 minutes. No treatments or interventions are provided as part of this study.

The results will contribute to understanding how knowledge about pain, coping strategies, and sexual function interact in people with chronic pelvic pain and may inform future educational and clinical approaches.

Chronic pelvic pain (CPP) is defined as persistent or recurrent pelvic pain lasting at least six months and is associated with substantial physical, psychological, and social consequences. Beyond pain intensity, cognitive and emotional factors such as knowledge about pain mechanisms, pain-related beliefs, and coping strategies play an important role in the experience of chronic pain. Sexual function is frequently affected in people with CPP, and this impairment may be influenced not only by nociceptive factors but also by cognitive and affective variables.

The primary objective of this study is to analyze the associations between knowledge about pain, coping strategies, and sexual function in adults with chronic pelvic pain. Secondary objectives include describing these variables in the study population and examining differences according to sex and educational level.

This is an observational, analytical, cross-sectional study. Adult participants (≥18 years) with a clinical diagnosis of chronic pelvic pain will be recruited from hospital outpatient clinics. Exclusion criteria include current pregnancy, recent major pelvic surgery, active pelvic infection or neoplasm, inability to understand Spanish, or cognitive impairment preventing completion of questionnaires.

After providing written informed consent, participants will complete a set of self-administered questionnaires during a single assessment session. Data collected will include sociodemographic variables (age, sex, educational level), pain duration, pain intensity measured by a visual analogue scale, level of knowledge about pain assessed through a brief ad hoc questionnaire developed for this study with content validation, coping strategies assessed using the Pain Catastrophizing Scale (PCS), and sexual function assessed using the Arizona Sexual Experience Scale (ASEX). No intervention or modification of usual clinical care is involved.

Data analysis will include descriptive statistics and appropriate comparative and correlational analyses to explore relationships between knowledge, coping strategies, and sexual function. The study involves minimal risk to participants and guarantees voluntary participation, anonymity, and confidentiality of data. Ethical approval will be obtained from the Research Ethics Committee of the Principality of Asturias prior to study initiation.
