Objectives: The objective of this manuscript is to translate, adapt, and validate an Arabic version of the Diabetes Eating Problem Survey—Revised (DEPS-R) questionnaire to assess disordered eating behaviors (DEBs) in adolescents with T1D in Saudi Arabia. Additionally, the study sought to estimate the prevalence of DEBs and analyze its associations with glycemic control and diabetes-related complications. Methods: A cross-cultural validation study was conducted following the COSMIN guidelines. The DEPS-R questionnaire was translated into Arabic through forward and backward translation involving expert panels, including psychiatrists, diabetologists, and linguists. A sample of 409 people with type 1 diabetes (PwT1D) (58.4% females) aged 12–20 years was recruited from outpatient diabetes clinics in the five main regions of Saudi Arabia. Participants completed the Arabic DEPS-R and the validated Arabic version of the SCOFF questionnaire. Sociodemographic, anthropometric, and biochemical data were collected, and statistical analyses, including confirmatory factor analysis (CFA) and internal consistency tests, were conducted. Results: The Arabic DEPS-R exhibits strong internal consistency (Cronbach’s alpha = 0.829) and high test–retest reliability (ICC = 0.861), with a CFA supporting a three-factor structure, namely body weight perception, disordered eating behaviors (DEBs), and bulimic tendencies. Notably, higher DEPS-R scores are significantly linked to elevated HbA1c levels, increased BMI, and more frequent insulin use. Alarmingly, 52.8% of participants show high-risk DEB, which is directly associated with poor glycemic control (HbA1c ≥ 8.1%) and a heightened risk of diabetic ketoacidosis (DKA). Conclusions: The Arabic DEPS-R is a valid and reliable tool for screening DEBs among Saudi adolescents with T1D. Findings underscore the necessity for early identification and intervention to mitigate the impact of EDs on diabetes management and overall health outcomes.

Background: Migraine is a highly prevalent neurological disorder and a leading cause of disability, particularly among working-age adults. Although the Work Productivity and Activity Impairment (WPAI) questionnaire is widely used to assess the functional impact of health conditions, no validated Arabic version specific to migraine is currently available. This study was conducted to validate the Arabic version of the WPAI:Migraine questionnaire among Arabic-speaking migraine patients in Saudi Arabia. Methods: A cross-sectional psychometric validation study was conducted at a tertiary headache clinic between June 2023 and January 2024. Adult patients diagnosed with episodic or chronic migraine, based on the International Classification of Headache Disorders, 3rd edition (ICHD-3), completed the Arabic version of the WPAI:Migraine and the validated Arabic version of the Migraine Disability Assessment Scale (MIDAS). Test–retest reliability was assessed after two weeks. Psychometric properties, including reliability, criterion validity, and known-group validity, were evaluated using intraclass correlation coefficients (ICCs), Pearson’s and Spearman’s correlations, and one-way ANOVA. Results: Eighty-two patients completed the study (76.8% female; mean age 38 ± 11 years). The Arabic WPAI:Migraine questionnaire demonstrated substantial-to-almost-perfect test–retest reliability (ICC range: 0.68–0.84). WPAI:Migraine domain scores correlated significantly with MIDAS scores—particularly for activity impairment (r = 0.576), presenteeism (r = 0.526), and absenteeism (r = 0.522)—and increased consistently across MIDAS disability grades, supporting validity. Conclusions: The Arabic WPAI:Migraine questionnaire is a valid and reliable instrument for assessing work productivity and activity impairment among Arabic-speaking migraine patients, suitable for clinical and research use.
