This study aims to develop and validate a novel Turkish-language self-report instrument, the Kinesiophobia Severity Scale in Urinary Incontinence (KSS-UI), to assess movement avoidance and fear of movement associated with concerns about urinary leakage in individuals with urinary incontinence. Following scale development, its validity and reliability will be evaluated through psychometric analyses in accordance with the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) recommendations.
This methodological study aims to develop and evaluate the validity and reliability of the Kinesiophobia Severity Scale in Urinary Incontinence (KSS-UI), a novel Turkish-language self-report instrument designed to assess fear of movement and movement avoidance associated with concerns about urinary leakage.
The study will include individuals with urinary incontinence, including stress, urgency, and mixed urinary incontinence. Participants will be recruited exclusively from individuals reporting urinary incontinence among relatives of patients attending the Physical Therapy and Rehabilitation Center. Individuals who meet the eligibility criteria and voluntarily agree to participate will be enrolled in the study. Written informed consent will be obtained from all participants before data collection.
Initially, an item pool was developed through a comprehensive literature review, semi-structured interviews with 15-20 individuals with urinary incontinence, and recommendations from experts in relevant clinical disciplines. Following ethical approval, the items will undergo content validity assessment by a multidisciplinary panel of at least 10 experts. Item relevance, clarity, simplicity, and necessity will be evaluated using the Content Validity Ratio (CVR), Content Validity Index (CVI), and modified kappa statistics.
Subsequently, face validity and comprehensibility will be assessed through cognitive interviews with 8-12 individuals. Items will be revised based on participant feedback. Pilot testing will be conducted to examine item distributions, floor and ceiling effects, corrected item-total correlations, internal consistency, and item discrimination.
Following these preliminary evaluations, the revised scale will be administered to eligible participants during a single assessment session. Questionnaire completion is expected to take approximately 15-20 minutes.
Psychometric analyses will be performed to evaluate the validity and reliability of the scale. Based on the findings, the final scale will be established, and a scoring and interpretation guide will be developed.
The study is expected to provide a valid and reliable instrument for assessing urinary incontinence-related kinesiophobia and contribute to the evaluation of movement-related fear and avoidance behaviors in individuals with urinary incontinence.
Ahi Evran University Education and Research Hospital is the lead sponsor of 39 studies on the registry; 4 are open to participants now.
Counted across the registry records on this site, refreshed daily.
The study population will consist of adults aged 18 years or older who report urinary incontinence, including stress, urgency, and mixed urinary incontinence. Participants will be recruited from among relatives of patients attending the Physical Therapy and Rehabilitation Center. Eligible individuals who report urinary leakage at least once per week during the past three months, are able to read and understand Turkish, and voluntarily agree to participate will be included in the study. Individuals with active lower urinary tract infections or conditions that prevent independent completion of the questionnaires will be excluded.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

This group will consist of individuals with urinary incontinence, including stress, urgency, and mixed urinary incontinence, who are recruited from among relatives of patients attending the Physical Therapy and Rehabilitation Center. Eligible participants who voluntarily agree to participate will complete the newly developed Kinesiophobia Severity Scale in Urinary Incontinence (KSS-UI) to assess fear of movement and movement avoidance associated with concerns about urinary leakage. The scale will undergo psychometric evaluation to assess its validity and reliability. No therapeutic intervention will be administered as part of the study.
Content Validity of the Kinesiophobia Severity Scale in Urinary Incontinence (KSS-UI)
The content validity of the newly developed scale will be evaluated by a multidisciplinary panel of at least 10 experts. Item relevance, clarity, simplicity, and necessity will be assessed using the Content Validity Ratio (CVR), Item-level Content Validity Index (I-CVI), Scale-level Content Validity Index (S-CVI), and modified kappa statistics.
Time frame: During the initial expert evaluation, before participant recruitment for the main validation study.
Internal Consistency of the KSS-UI
The internal consistency of the KSS-UI will be evaluated using Cronbach's alpha coefficient and corrected item-total correlations. The contribution of individual items to scale reliability will also be examined.
Time frame: Baseline (single assessment session; approximately 15-20 minutes).
Item Discrimination and Item Performance of the KSS-UI
Item performance will be evaluated by examining item distributions, floor and ceiling effects, and corrected item-total correlations. Item discrimination will be assessed by comparing item scores between the upper and lower 27% of participants based on total scale scores.
Time frame: Baseline (single assessment session; approximately 15-20 minutes).
Plan to share: No — Individual participant data will not be shared to protect participants' privacy and confidentiality, given the sensitive nature of urinary incontinence-related health information. Study findings will be reported in aggregate form.
