Chronic Pain, Emotions and Professional Football
調査の概要
詳細な説明
Chronic pain is now widely recognized as a complex biopsychosocial condition rather than a purely physical phenomenon. The International Association for the Study of Pain (IASP) defines pain as an "unpleasant sensory and emotional experience," and neuroimaging studies reveal that chronic pain involves shifting brain activation from nociceptive to cognitive and emotional circuits over time. This evolving understanding underscores the role of emotions, cognitions, and psychosocial factors in shaping the pain experience and contributes to the clinical difficulty of managing chronic pain.
Psychological factors-including fear-avoidance, catastrophizing, and depression-are known to strongly influence pain severity and disability. While these constructs are often tied to biomedical explanations (e.g., structural imaging findings), such explanations may increase fear or negative expectations and do not fully account for pain severity in many individuals. Social factors also interact with psychological processes to shape pain experiences, yet they remain understudied. One such social factor may be the emotional impact of a chronic pain sufferer's favorite sports team performance.
Sports fandom research demonstrates that strong fan identification provides psychological benefits such as belonging, self-esteem, and life satisfaction. Neuroimaging evidence suggests that sports-related wins activate reward networks, while losses trigger introspective and negative emotional states. Despite these findings, the potential link between weekly sports team performance and symptom fluctuations in people living with chronic pain has not been directly investigated.
This longitudinal observational study will examine whether weekly changes in the performance of participants' preferred NFL football team correlate with changes in self-reported chronic pain intensity (Numeric Pain Rating Scale), depressive symptoms (PHQ-2), and pain catastrophization (Pain Catastrophizing Scale). Participants will be adults aged 18 or older with chronic pain lasting more than one year and who meet predefined criteria for being avid fans of a current NFL team.
Following informed consent, participants will complete baseline demographic and clinical questionnaires. Each week throughout the NFL regular season, participants will receive a brief online survey assessing their pain and depressive symptoms. Independent of participant responses, the research team will document whether the participant's team played, whether they won or lost, and the performance of the team's primary rival.
Data will be analyzed descriptively and through inferential statistics to determine whether emotional changes associated with team performance are associated with clinically meaningful weekly changes in pain, depression, or catastrophizing. This study aims to generate preliminary evidence regarding the interaction between sports-related emotional experiences and chronic pain, potentially identifying a novel social component relevant to understanding pain variability.

Cohort 1: Avid NFL Fans with Chronic Pain
Participants in this cohort are adults aged 18 or older who have experienced chronic pain for more than one year and meet predefined criteria for being avid fans of an active U.S. professional football (NFL) team. All participants will complete baseline demographic and clinical questionnaires and will provide weekly self-reported measures of pain intensity (NPRS) and depressive symptoms (PHQ-2) throughout the NFL regular season. Team performance variables (game played, win/loss outcome, rival results) will be collected by the research team. Study Activities: Baseline demographic and football-related fan profile questionnaire Baseline Pain Catastrophizing Scale (PCS) Weekly NPRS and PHQ-2 surveys End-of-season PCS Research team documentation of weekly team performance and rival performance Purpose: To evaluate whether weekly NFL team performance is associated with fluctuations in pain intensity, depressive symptoms, and catastrophizing in individuals living with chronic pain |

メジャーの説明 |
時間枠 |
|---|---|---|
|
Pain Intensity (Numeric Pain Rating Scale - NPRS)
時間枠:Weekly assessments from study enrollment through the end of the NFL regular season (approximately September 2025 to January 2026).
|
Self-reported musculoskeletal pain intensity will be measured using the 0-10 Numeric Pain Rating Scale (NPRS), where 0 indicates "no pain" and 10 indicates "worst pain imaginable."
Participants will report their average pain over the past week.
|
Weekly assessments from study enrollment through the end of the NFL regular season (approximately September 2025 to January 2026).
|
|
Depressive Symptoms (Patient Health Questionnaire-2 - PHQ-2)
時間枠:Weekly assessments from study enrollment through the end of the NFL regular season (approximately September 2025 to January 2026).
|
Depressive symptoms will be measured using the 2-item PHQ-2, assessing anhedonia and depressed mood.
Each item is rated 0 (not at all) to 3 (nearly every day), generating a score from 0-6.
|
Weekly assessments from study enrollment through the end of the NFL regular season (approximately September 2025 to January 2026).

Pain Catastrophizing (Pain Catastrophizing Scale - PCS)
時間枠:Weekly assessments from study enrollment through the end of the NFL regular season (approximately September 2025 to January 2026).
|
The PCS is a 13-item questionnaire assessing rumination, magnification, and helplessness related to pain.
Each item is rated 0-4, with total scores ranging from 0-52.
Higher scores indicate greater catastrophizing.
|
Weekly assessments from study enrollment through the end of the NFL regular season (approximately September 2025 to January 2026).

|
Correlation Between Weekly Team Performance and Symptom Changes
時間枠:Weekly assessments from study enrollment through the end of the NFL regular season (approximately September 2025 to January 2026).
|
Team performance will be operationalized as: Win, Loss, or Did Not Play, Rival team win/loss, Margin of victory/defeat. These variables will be analyzed against weekly NPRS and PHQ-2 scores to determine associations between sports-related emotional events and chronic pain symptoms. |
