The American questionnaire SF-36 Health Survey is a worldwide tool used to assess the quality of life. It becomes increasingly popular also in Poland. Unfortunately, the existing Polish studies that used the questionnaire are not entirely reliable because different linguistic versions have been applied in the studies. The basic psychometric properties, like reliability and validity estimates of these versions have not been defined. The goal of the paper is to present the study aimed at evaluating the Polish version that has been acquired at The Qualitymetric--the unique entitled distributor of the SF-36v2--in terms of its utility for the Polish population. One thousand seventy six people took part in the study. On the basis of this study, the factor analysis, discriminant validity of the items and reliability and validity tests have been performed. The results showed that the factor structure of the Polish version of SF-36v2 differs from its original American version. However, it has been decided to maintain the original subscales in the Polish version of SF-36v2 in order to make comparisons between the Polish data and the data available abroad. The reasonable indicators of validity and reliability of the Polish version of SF-36v2 do support this decision. Nevertheless, some caution is recommended while interpreting the results of this version.

Introduction: Assessing the quality of life (QoL) in patients with various diseases is essential for understanding their well-being and guiding clinical management. Dermatological conditions, particularly those affecting the scalp, significantly impact QoL due to their visible nature, which can affect appearance and social interactions. While general QoL instruments like the Dermatology Life Quality Index (DLQI) exist, disease-specific tools like SCALPDEX are necessary for capturing the unique challenges faced by patients with scalp disorders.

Introduction: Older adults represent a growing proportion of the general population. Nonsteroidal anti-inflammatory drugs (NSAIDs) constitute a group of medicines that are both necessary, owing to their anti-inflammatory, analgesic, and cardioprotective abilities, and potentially harmful, owing to their side effects.
Objectives: This study provides a comprehensive analysis of NSAID usage patterns among Polish adults aged 60 years and older.

Objective: The aim was to establish the validity and reliability of the English version of MisoQuest, a 14-item misophonia questionnaire initially validated in the Polish language.
Design: Reliability was examined through internal consistency, measurement error, and test-retest reliability. Validity was evaluated with confirmatory factor analysis, convergent, and discriminant validity.

Purpose: Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental condition that affects approximately 5% of the pediatric population, with increased prevalence among those with type 1 diabetes (T1D). Reports suggest that unrecognized and untreated ADHD impairs T1D control and that ADHD may be underdiagnosed in the Polish population. The International Society for Pediatric and Adolescent Diabetes recommends neurodevelopmental assessments in children with T1D, but specific guidelines on procedures and implementation are lacking.
