Abstract:
Medical Fear Survey (MFS) was designed to assess the fear of medical treatments and related factors through five dimensions including fears of injections and blood draws, sharp objects, blood, mutilation, medical examination and physical symptoms. We analysed the factor structure and validity of a short version of MFS in Hungarian, on a large sample (2631 participants; 558 men, 2067 women) focusing on possible age and gender differences (aged Mean = 30.4, SD = 13.4), which were not reported for the original version. Furthermore, using discriminant analysis, potential screening function of the MFS-short was examined. Results supported construct and convergent validity and scale-reliability for the five-factor structure of the MFS-short. Further analyses demonstrated excellent discriminatory power for four subscales, while one subscale had acceptable power. Our findings provide implications for the utility of MFS-short as a screening measure in assessing the severity of medical fears controlling for gender differences and age-biases.
Insights
The Medical Fear Survey-short (MFS-short) effectively screens for medical fears in adults, showing good validity and reliability across different ages and genders. This tool helps assess the severity of medical anxieties.
Area of Science:
- Psychological Assessment
- Medical Psychology
- Health Psychology
Background:
- Medical fears are common and can impact healthcare engagement.
- Existing measures may not adequately capture the nuances of medical-related anxieties.
- The Medical Fear Survey (MFS) was developed to address these fears across multiple dimensions.
Purpose of the Study:
- To analyze the factor structure and validity of a short version of the MFS (MFS-short) in a Hungarian sample.
- To investigate potential age and gender differences in medical fears using the MFS-short.
- To examine the screening utility of the MFS-short via discriminant analysis.
Main Methods:
- A large sample of 2631 Hungarian adults (558 men, 2067 women) completed the MFS-short.
- Factor analysis was used to assess the scale's structure.
- Discriminant analysis evaluated the screening power of the MFS-short subscales.
Main Results:
- The MFS-short demonstrated strong construct and convergent validity and scale reliability.
- A five-factor structure was confirmed for the MFS-short.
- Four subscales showed excellent discriminatory power, with one exhibiting acceptable power for screening medical fears.
Conclusions:
- The MFS-short is a reliable and valid instrument for assessing medical fears.
- It can be utilized as a screening measure, accounting for gender and age variations.
- Findings support its application in clinical and research settings for understanding medical anxieties.
