The Pre-Exposure Prophylaxis Stigma Scale: Measurement Properties of an Adaptation in German and French.

Objectives: This study aimed to adapt and validate the HIV PrEP Stigma Scale (HPSS) in French and German languages (HPSS-FR/DE) and assess its applicability across diverse linguistic and cultural contexts. Methods: The original scale was adapted to French and German and administered through an online survey in multiple European nations. A four-factor structure was extracted from the data, including negative social consequences, social pressure, self-support, and external support. The scale's construct validity, reliability, and cross-linguistic consistency were evaluated. Results: The adapted HPSS-FR/DE demonstrated robust psychometric properties, good construct validity, acceptable reliability, and consistent measurement across different languages. This adaptation enhances its utility in multicultural settings, offering a comprehensive tool to assess PrEP-related stigma. Conclusion: This study provides a suitable tool to address PrEP stigma in multicultural environments to enhance PrEP uptake and adherence among men who have sex with men. Moreover, it lays the groundwork for further investigations into PrEP stigma across diverse populations and cultural settings, enabling the development of targeted public health interventions and policies to combat this issue effectively.

Assessing health insurance literacy in Switzerland: first results from a measurement tool.

BACKGROUND: Health insurance literacy (HIL) is crucial for individuals to make informed-decisions and navigate complex choice-based health insurance systems. However, there is a lack of evidence on HIL in countries outside the US, with Switzerland no exception. METHODS: Using the HILM-CH, a survey instrument developed to measure HIL in Switzerland, this study first describes the answers to the HILM-CH. Second, the study uses ordinary least squares and quantile regressions to investigate the associations between the HIL score and demographic, socioeconomic, health, and preference factors in the German, French, and Italian Swiss regions. RESULTS: A third of the population faces difficulties in finding health insurance information. Understanding it and managing the financial aspects of the Swiss health insurance system pose the biggest barriers to the population. The HIL score significantly and positively correlates with age and financial risk, while non-Swiss individuals have lower HIL scores. No association was found between HIL, gender, education and time preference. There is a small health gradient, with more doctor visits associated with higher HIL in the lowest quantiles of the HIL score. Similarly, wealthier individuals in the Swiss German part of Switzerland have a higher HIL when choosing their health insurance. CONCLUSION: This study provides important insights into Swiss HIL and its associated factors. These findings contribute to the international literature on HIL and highlight the importance of understanding variations in HIL and various factors in choice-based health insurance systems.

The Swiss Health Insurance Literacy Measure (HILM-CH): Measurement Properties and Cross-Cultural Validation.

BACKGROUND: Most consumers face difficulties when choosing and navigating health insurance plans. Health insurance literacy (HIL) has been discussed as a critical lever to ensure efficient choices and navigation in choice-based health insurance systems. Still, existing evidence about HIL mainly comes from the US, and the only validated scale, the Health Insurance Literacy Measure (HILM), may not be adequate to measure HIL outside US samples. This paper describes the measurement properties of the Swiss Health Insurance Literacy Measure (HILM-CH), the first scale to measure HIL in Switzerland. METHODS: The items of the HILM-CH were adapted from the HILM in German, French, and Italian. A panel of experts refined it to ensure its suitability for the Swiss context. The final version of the HILM-CH contains 21 items, and other relevant measures were administered in the Swiss Health Insurance Literacy Survey to a sample of 6036 insurees. Measurement properties were investigated overall and per linguistic group. Internal reliability was determined using Cronbach's alphas. Criterion validity was examined through convergent and concurrent validity of the HILM-CH. The construct validity was assessed using factor analysis. Measurement invariance of the HILM-CH between linguistic regions was further evaluated using multiple-group confirmatory factor analyses. RESULTS: The HILM-CH had acceptable to good reliability (alphas between 0.70 and 0.91). Concurrent and convergent validity showed that HILM-CH is a good measurement of HIL. Factor analysis revealed a four-factor model and showed an acceptable fit to the data (CFI= 0.977; TLI = 0.974; RMSEA = 0.061; SRMR = 0.032). Using the established four-factor model, measurement invariance was established across Switzerland's German, French, and Italian-speaking regions. CONCLUSIONS: The HILM-CH is a reliable and valid measure of HIL across Switzerland's German, French, and Italian-speaking regions. It can be used in future research to find associations between HIL and individual characteristics.
