Brief Summary

The purpose of this study is to develop a multidimensional screening tool for Work-Related Musculoskeletal Disorders (WMSDs) and to evaluate its psychometric properties. The study involves a cross-sectional survey of approximately 250 workers in the bio-pharmaceutical industry to assess the tool's structural validity, internal consistency, construct validity, and measurement invariance following COSMIN guidelines.

Conditions

Musculoskeletal Diseases; Occupational Diseases; Work-Related Musculoskeletal Disorders

Keywords

WMSDs; Musculoskeletal Pain; Screening Tool; Psychometrics; Occupational Health

Outcome Measures

Primary Outcomes (1)

• Structural Validity

  Evaluated using Confirmatory Factor Analysis (CFA). Model fit will be assessed based on stricter criteria: CFI ≥ 0.95, TLI ≥ 0.95, RMSEA ≤ 0.06, and SRMR ≤ 0.08 (Hu \& Bentler, 1999). If model fit is insufficient, modification indices (MI) will be used to adjust the model within theoretically justifiable limits.

Study Arms (1)

Bio-pharmaceutical Industry Workers

Workers currently employed at Samsung Biologics, including both office and production staff, who meet the inclusion criteria for musculoskeletal symptoms.

Other: Survey Administration

Interventions

Survey Administration OTHER

Participants will complete the newly developed multidimensional screening tool and standard validation questionnaires (e.g., OSPRO-YF, FABQ, TSK) to assess musculoskeletal symptoms and psychosocial factors.

Bio-pharmaceutical Industry Workers

Eligibility Criteria

• Age: 19 Years - 65 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

The study population consists of workers currently employed at a bio-pharmaceutical company (Samsung Biologics) in South Korea. This includes both office workers engaged in VDT tasks and production workers involved in physical tasks who report musculoskeletal symptoms.

You may qualify if:

• Current regular employees working at the study site.
• Adults aged 19 years or older who understand the study purpose and procedures and voluntarily agree to participate in writing.
• Participants capable of reading, understanding, and self-responding to the questionnaire.
• Individuals with musculoskeletal symptoms according to NIOSH standards: symptoms lasting more than one week OR recurring at least once a month in the past 12 months (symptoms include pain, aching, stiffness, burning sensation, tingling, or numbness).

You may not qualify if:

• Individuals with cognitive or mental impairments that make it difficult to understand the study or complete the survey.
• Individuals suspected of having a medical emergency or severe disease requiring immediate medical attention.
• Individuals deemed unsuitable for participation by the researcher.
