Development and Psychometric Validation of a Knowledge Assessment Tool on Radiotherapy Resistance Among Oncologists in Iraq Bassam Abdul Rasool Hassan, Ali Haider Mohammed, Ahmed Zuhair Abdulhameed Alsammarraie, Musaab Kadhim Alabboodi Journal of Cancer Education, 2026 Radiotherapy resistance (RTR) is a significant barrier in oncology, affecting treatment outcomes and clinical decision-making. Despite its importance, no standardized tool exists to measure oncologists' knowledge of RTR. This study aimed to develop and validate a comprehensive questionnaire to assess oncologists' knowledge of RTR. A 29-item questionnaire was developed following a multi-phase process. An initial pool of 45 items was refined through content and face validity assessments by a panel of 5 experts, leading to item revisions and deletions. Data were collected from 400 oncologists in Iraq. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted to establish construct validity, while Cronbach's alpha, Composite Reliability (CR), and Item Response Theory (IRT) analysis were used to assess internal consistency and item performance. EFA confirmed the eight-domain structure of the questionnaire, with factor loadings exceeding 0.70 for all items. CFA demonstrated good model fit, with indices of CFI = 0.92, TLI = 0.91, and RMSEA = 0.06. Internal consistency was high, with a Cronbach's alpha of 0.93 and a CR of 0.94 for the overall questionnaire. IRT analysis revealed that all items had acceptable difficulty, discrimination, and guessing parameters, indicating that the items effectively differentiate oncologists with varying levels of knowledge. The final 29-item questionnaire covered key RTR domains, including Conventional and Combined Therapies, Radioresistance, and Sensitivity and Resistance. The validated 29-item knowledge questionnaire demonstrated strong psychometric properties, making it a reliable tool for assessing oncologists' knowledge of RTR. This tool can support oncology education, training, and research. Future studies should focus on cross-cultural validation, test–retest reliability, and examining how RTR knowledge influences clinical decision-making. This tool is especially relevant for improving oncology training and clinical decision-making in Iraq, where systemic barriers such as limited equipment, training gaps, and uneven access to radiosensitizers challenge cancer care.
Experiential learning to advocacy: A peer-led approach to safe medication disposal in pharmacy education Jia Jia Lee, Li Ling Yeap, Ali Haider Mohammed, Chuan Sheng Yap, Bassam Abdul Rasool Hassan, et al. Plos One, 2026 Introduction Safe medication disposal is crucial for public health and environmental sustainability, yet public awareness remains limited. While educational campaigns exist, pharmacy students can serve as key advocates in promoting proper disposal practices. This study integrates experiential learning and peer-led education to enhance students’ advocacy skills. Methods A two-phase mixed-method approach was used. In Phase 1, 35 pharmacy student ambassadors underwent hands-on training at community pharmacies, actively participating in medication take-back programs. Their experiences were documented and analyzed thematically. In Phase 2, they conducted a peer-led workshop for 43 undergraduate pharmacy students. A pre- and post-test assessed knowledge improvement among workshop participants. Results The thematic analysis identified five key themes: increased awareness, recognition of environmental and health risks, sense of responsibility, motivation for advocacy, and challenges in promoting safe disposal. Knowledge among workshop participants significantly improved, increasing from mean score 6.86 to 8.44 (Z = −4.827, p < 0.001), demonstrating the effectiveness of peer-led education. Conclusion Experiential learning combined with peer-led education effectively strengthened pharmacy students’ knowledge and advocacy for safe medication disposal. Engaging students as educators not only enhanced their own competencies but also improved awareness among peers. This approach empowers future pharmacists to advocate for responsible disposal practices within their communities.
Vitamin D Deficiency in Al-Madinah Al-Munawwarah: A Cross-sectional Study of Prevalence Among Saudi and Non-Saudi Population Muhammed Hassan Nasr, Noordin Othman, Bassam Abdulrasool Hassan, Mahmathi Karuppannan, Noorizan Binti Abdulaziz, et al. Journal of Pharmacology and Pharmacotherapeutics, 2026 Background Vitamin D deficiency poses significant health risks globally, impacting bone health and immune function. In Saudi Arabia, where environmental and lifestyle factors limit sun exposure, vitamin D deficiency is especially prevalent. This study assesses vitamin D deficiency in Al-Madinah, focusing on differences between Saudi nationals and non-Saudi residents. Purpose The primary aim was to determine the prevalence of vitamin D deficiency among Saudis and non-Saudis and identify lifestyle and dietary factors contributing to deficiency. Materials and Methods Conducted from October 2017 to May 2018, this cross-sectional study included 65 non-diabetic male participants aged 18–65, divided into two groups: Saudi ( n = 33) and non-Saudi ( n = 32). Exclusion criteria included conditions affecting vitamin D metabolism. Data were collected on demographics, dietary habits, sun exposure, and anthropometric measurements. Serum 25-hydroxyvitamin D levels were measured, and logistic regression was used to identify predictors of deficiency. Results Vitamin D deficiency was significantly higher in Saudis (91%) than in non-Saudis (47%). Limited sun exposure, lower intake of vitamin D-rich foods, and occupation type were associated with higher deficiency rates among Saudis. Logistic regression revealed that occupation was a positive predictor, while liver consumption was a negative predictor of deficiency. Conclusion This study highlights the urgent need for targeted public health interventions in Saudi Arabia to address vitamin D deficiency, recommending dietary changes and vitamin D supplementation. Further research should investigate genetic and environmental factors affecting vitamin D levels across different populations in the region.
Knowledge, attitudes and practices toward skin cancer prevention among Malaysian adults: a cross-sectional online survey Ali Haider Mohammed, Bassam Abdul Rasool Hassan, Yen Jun Wong, Loh Hui Ying, Marcus Loh Boon Hong, et al. BMJ Open, 2026 Objectives To assess the levels of knowledge, attitudes and practices (KAP) toward skin cancer prevention among Malaysian adults and to examine differences in KAP across socio-demographic groups. Design Cross-sectional online survey. Setting Community-based study conducted in Malaysia using social media recruitment. Participants A total of 386 adults aged ≥18 years residing in Malaysia. Most participants were young adults (86.3%), female (55.4%) and of Chinese ethnicity (65.5%). Healthcare professionals were excluded. Primary and secondary outcome measures Primary outcomes were levels of knowledge, attitude and preventive practices toward skin cancer, measured using the validated KAP-SC-Q (Knowledge, Attitude and Practice of Skin Cancer Questionnaire) and categorised as poor, moderate or good. Secondary outcomes included differences in KAP across socio-demographic and clinical characteristics, analysed using independent t-tests and χ 2 tests. Results Over half of participants demonstrated poor knowledge of skin cancer (56.0%) and the vast majority showed inadequate preventive practices (84.2%), while attitudes toward skin cancer were predominantly positive (62.4%). Significant differences in mean KAP scores and categorical levels were observed across several socio-demographic variables. Participants with tertiary education had higher knowledge (14.32 vs 12.61) and attitude scores (20.01 vs 15.95; p<0.001) than those with lower education. Individuals with a diagnosis of skin disease had significantly higher knowledge (14.95 vs 13.03; p=0.001), attitude (20.03 vs 18.21; p=0.007) and practice scores (12.10 vs 9.72; p<0.001). Personal history of skin cancer and severe sunburn was associated with better preventive practices but poorer attitudes (p<0.001), and light-skinned participants were more likely to have poor knowledge and attitudes (p<0.05). Conclusions Malaysian adults exhibited limited knowledge and very poor preventive practices toward skin cancer despite generally positive attitudes. These findings highlight substantial gaps between awareness and behaviour and support the need for targeted public health interventions to correct misconceptions, improve risk perception especially in high-risk groups and promote effective ultraviolet protection behaviours.
Validation of the abridged version of the autism-spectrum quotient (AQ-28) in the Arabic-speaking adult general population Feten Fekih-Romdhane, Fouad Sakr, Amthal Alhuwailah, Leila Sarra Chaibi, Mai Helmy, et al. Journal of Public Health Research, 2025 Background: The field of autism research in adults has not yet emerged in Arab countries, which is in part due to the lack of valid, reliable autism measures. The objectives of this study were to assess the psychometric properties of the abridged version of the autism-spectrum quotient (AQ-28) in a sample of non-clinical Arabic-speaking adults. Methods: A cross-sectional web-based study was carried-out from February to April 2024. Adults aged over 18 years from the general population of Lebanon ( N = 1076, mean age of 27.90 ± 11.81 years, 63.8% females) were recruited using the snowball sampling technique. The AQ-28 was administered to participants, along with the relationship Questionnaire, the Patient Health Questionnaire-9, the Generalized Anxiety Disorder-7, and the Jong-Gierveld Loneliness Scale. Results: The original five-factor model of the AQ-28 had good fit to the data: RMSEA = 0.061 (90% CI: 0.059–0.064), SRMR = 0.060, CFI = 0.848, TLI = 0.831, and an excellent internal consistency (Cronbach’s α = 0.91). Measurement invariance has been established across sex. Mean sum scores observed in male participants were significantly higher than those displayed by females. Autistic traits as measured by the Arabic AQ-28 correlated positively with loneliness ( r = 0.16; p < 0.001), depression ( r = 0.17; p < 0.001) and anxiety ( r = 0.15; p < 0.001). Conclusion: Findings suggest that Arabic-language version of the AQ-28 provided by this study is valid, reliable, and suitable for use among Arabic-speaking adults to measure core trait dimensions of autism and screen for autism spectrum disorder. It is our hope that the new scale will generate interest among researchers in the yet unexplored field of autism research in Arab countries.
