Abstract:
Introduction. Osteoporosis remains a major public health issue, particularly affecting the elderly, and is characterized
by decreased bone mass and deterioration of bone structure, increasing the risk of severe fractures. The development of
specific and precise tools that allow for the identification and estimation of the influence of modifiable factors on the development of osteoporosis is an important step in early intervention for at-risk individuals.
Material and methods. The initial version of the questionnaire was created to identify modifiable factors contributing to
the development of osteoporosis, including the type and frequency of drinking water consumption, water quality, knowledge about its mineral composition, dietary preferences, alcohol and tobacco use, physical activities, and stressful situations.
The questionnaire initially contained 65 questions, organized into three sections. Five experts reviewed the content validity,
evaluating the clarity, cultural and linguistic relevance, structure, and coherence of the questions. The feedback led to adjustments, reducing the questionnaire to 52 questions. A pre-test was conducted with 30 adults from the Republic of Moldova,
confirming the validity and internal consistency of the questionnaire, with a Cronbach’s Alpha coefficient of 0.768.
Results. To ensure content validity, experts evaluated the questionnaire, and based on their comments and suggestions, semantic and syntactic reformulations and modifications were made. As a result, 13 questions were eliminated, reducing the
second version of the questionnaire to 52 questions. During the pre-testing stage, the order and content of the questions
were deemed appropriate by the respondents. The average time required to complete the questionnaire was 14.19 minutes (SD ± 1.567), with a minimum of 11.90 minutes and a maximum of 17.33 minutes. The sample used in the pre-testing
stage included 30 respondents, the majority of whom (93.3%) were women. The respondents’ ages ranged from 25 to 72
years, with a mean age of 50.37 ± 2.6 years. The distribution of respondents was balanced between urban (53.3%) and
rural (46.7%) areas. Regarding education level, 56.6% had higher education, 26.7% had secondary vocational education,
and 16.7% had no higher education.
Conclusions. The study demonstrated that the new questionnaire is a valid and reliable instrument for assessing the
impact of modifiable risk factors on morbidity due to osteoporosis. Ongoing research is necessary to refine and further
validate the questionnaire within the broader population.
