The Validity Test of Anemia, Scabies and Pediculosis Capitis Screening Instruments in Students at Islamic Boarding School

Abstract

Students in Islamic boarding schools are known to have quite complex health vulnerability risks, such as the risk of infectious diseases (pediculosis capitis) and nutritional deficiency problems (anemia). Therefore, it is important to conduct screening to detect health problems early in the student population. Although several screening instruments have been used in the context of students, there has been no adequate research on the validity of these instruments. Based on these conditions, it is necessary to test the validity of existing screening instruments for pediculosis capitis and anemia in students. This study used a cross-sectional design to assess the validity of existing screening instruments. This study was conducted on 85 students aged 12-22 years in East Java. The screening tool used was a questionnaire, while anemia examination used a Hemoglobin (Hb) measuring instrument and pediculosis examination with physical examination as the gold standard method. The results of the anemia screening test showed a sensitivity value of 62% and a specificity of 91%. The scabies screening instrument showed a sensitivity of 68% and a specificity of 87%, which means it is quite good at detecting most cases of scabies, but there is still a risk of missing cases (sensitivity does not reach 100%). Pediculosis capitis screening showed a sensitivity of 78% and a specificity of 73%. A combination of a more comprehensive screening approach and interventions involving education, training, additional examinations, and collaboration with medical personnel is highly recommended.
