Illness Perception and Treatment Expectations in Lateral Elbow Pain (LEP-IPTE)
2026年7月20日 更新者：Hasan Gerçek、Acibadem University
Determining the Predictors of Illness Perception and Treatment Expectations in Individuals With Lateral Elbow Pain: A Cross-Sectional Study
This cross-sectional, correlational study aims to determine the predictors of illness perception and treatment expectations in adults with chronic lateral elbow pain.
Sociodemographic characteristics, clinical findings (pain intensity, pain duration, elbow-specific function) and psychosocial variables (pain self-efficacy, fear-avoidance beliefs, pain catastrophizing) will be examined as candidate predictors of two patient-centred constructs: illness perception, measured with the Brief Illness Perception Questionnaire, and treatment expectation, measured with the Treatment Expectation Questionnaire.
Data will be analysed using hierarchical multiple linear regression in three predictor blocks.
The study is reported according to the STROBE statement.

Adults with chronic lateral elbow pain
Adults aged 18 years or older, diagnosed with lateral epicondylalgia or lateral elbow pain by an orthopaedic surgeon or physiatrist, with pain of at least 4 out of 10 on the Numeric Rating Scale lasting 12 weeks or longer.
Participants complete a single battery of self-report questionnaires; no intervention is applied.

研究衡量的是什么？
主要结果指标
结果测量 |
措施说明 |
大体时间 |
|---|---|---|
|
Illness perception (Brief Illness Perception Questionnaire, B-IPQ)
大体时间：Single assessment at enrollment (Day 1)
|
The B-IPQ is a 9-item self-report instrument assessing cognitive and emotional representations of illness.
Eight items are rated on a 0 to 10 numeric scale covering consequences, timeline, personal control, treatment control, identity, concern, coherence and emotional representation; the ninth item is open-ended and asks about perceived causes.
The total score ranges from 0 to 80, with higher scores indicating a more threatening perception of the illness.
|
Single assessment at enrollment (Day 1)
|
|
Treatment expectation (Treatment Expectation Questionnaire, TEX-Q)
大体时间：Single assessment at enrollment (Day 1)
|
The TEX-Q assesses expectations of an upcoming treatment.
Fifteen scored items are rated on an 11-point scale from 0 (no expectation at all) to 10 (expecting complete recovery from treatment); six additional items are not included in scoring.
Higher scores indicate higher treatment expectation.

Single assessment at enrollment (Day 1)

次要结果测量
结果测量 |
措施说明 |
大体时间 |
|---|---|---|
|
Pain intensity (Numeric Rating Scale, NRS)
大体时间：Single assessment at enrollment (Day 1)
|
Self-reported lateral elbow pain intensity rated from 0 (no pain) to 10 (worst imaginable pain).
Higher scores indicate greater pain intensity.
|
Single assessment at enrollment (Day 1)
|
|
Pain self-efficacy (Pain Self-Efficacy Questionnaire, PSEQ)
大体时间：Single assessment at enrollment (Day 1)
|
Ten items rated on a 7-point Likert scale (0 = not at all confident, 6 = completely confident), giving a total score of 0 to 60. Higher scores indicate greater confidence in performing activities despite pain.
|
Single assessment at enrollment (Day 1)
|
|
Fear-avoidance beliefs (Fear-Avoidance Beliefs Questionnaire, FABQ)
大体时间：Single assessment at enrollment (Day 1)
|
Sixteen items rated on a 7-point Likert scale from 0 (completely disagree) to 6 (completely agree), assessing beliefs about the effect of physical activity and work on pain.
Higher scores indicate stronger fear-avoidance beliefs.
|
Single assessment at enrollment (Day 1)
|
|
Pain catastrophizing (Pain Catastrophizing Scale, PCS)
大体时间：Single assessment at enrollment (Day 1)
|
Thirteen items with helplessness, magnification and rumination subscales, each rated from 0 (never) to 4 (all the time), giving a total score of 0 to 52.
Higher scores indicate greater pain catastrophizing.
|
Single assessment at enrollment (Day 1)
|
|
Elbow pain and function (Patient-Rated Tennis Elbow Evaluation, PRTEE)
大体时间：Single assessment at enrollment (Day 1)
|
Fifteen items covering pain (5 items) and function (6 specific activity items and 4 usual activity items) over the past week.
The total score ranges from 0 to 100, with higher scores indicating greater pain and loss of function.
|
Single assessment at enrollment (Day 1)
