Abstract:
Introduction. Surgery exposes professionals to significant physical and psychological risks, including intense exertion,
prolonged static postures, and repetitive gestures, often leading to musculoskeletal pain. International studies report prevalence
rates above 90%, linked to long procedures and poor ergonomics, alongside exposure to biological and chemical
hazards, radiation, toxic smoke, and chronic stress. In the Republic of Moldova, occupational health in the medical sector is
underexplored, with no tools tailored to surgeons. This study aims to develop and validate the first nationally standardized
questionnaire to assess these risks and support public health policies.
Material and methods. The study used a sequential mixed-methods design: a qualitative phase to identify domains and
indicators, followed by a quantitative phase for psychometric testing. Four domains were defined: working conditions,
occupational factors, general health, and psycho-emotional state. The questionnaire was refined from 70 to 47 items after
expert review and validation, with internal consistency (Cronbach’s α) and content validity (I-CVI, modified Kappa) assessed.
It was pre-tested on 52 surgeons, and data were analyzed using SPSS 27 (p<0.05).
Results. Content validation revealed S-CVI/Ave values ranging from 0.934 to 1.00 and S-CVI/UA values from 0.738 to 1.00,
with all domains exceeding the accepted threshold for relevance and clarity, except for one domain, which fell slightly
below the recommended level for unanimous agreement. I-CVI values ranged from 0.857 to 1.00 (relevance) and 0.847 to
1.00 (clarity), while κ* indices were all rated as “excellent”. Based on expert feedback, 24 questions were revised and 15
were removed. Overall internal consistency was very good (α = 0.808), with section values ranging from 0.769 to 0.864, the
highest being for “Psycho-emotional state” (α = 0.864). The pre-test sample comprised 52 surgeons, mostly male (57.7%),
with a mean age of 44.92 years, predominantly from urban areas (92.3%). Respondents generally found the questions clear
but noted some lengthy formulations, repetitiveness, and sensitive items. These observations contributed to optimizing
the final version of the instrument.
Conclusions. The final questionnaire meets the initial theoretical dimensions and shows strong psychometric properties,
with high validity and internal consistency. The tool is comparable to established instruments and suitable for assessing
surgeons’ health and occupational risks, with potential for wider use.
