Abstract

Measurement of mental rotation presents a serious challenge to cognitive researchers owing to the lack of a single comprehensive measure that can be applied across the developing age groups. Objective of the present study was to develop and validate a new measure of mental rotation for preadolescent and adolescent age groups. Items were conceptualized and constructed based on existing theories. Study I checked the suitability of these items among preadolescent and adolescent age groups. After revisions, Study II was done to evaluate the item properties using item response theory. Subsequently done Confirmatory Factor Analysis provided evidence for the construct validity of the new measure. Finally, Study III was done to develop the age wise and gender wise norms for preadolescent and adolescent age groups. The newly developed measure was found to have sufficient reliability and validity and hence can be widely applied for measuring mental rotation of preadolescents and adolescents.

Abstract

Tens of millions of children are exposed to Mycobacterium tuberculosisglobally every year; however, there are no contemporary estimates of the risk of developing tuberculosis in exposed children. The effectiveness of contact investigations and preventive therapy remains poorly understood.

Abstract

Cough frequency, and its duration, is a biomarker that can be used in low-resource settings without the need of laboratory culture and has been associated with transmission and treatment response. Radiologic characteristics associated with increased cough frequency may be important in understanding transmission. The relationship between cough frequency and cavitary lung disease has not been studied.

7. Socioeconomic support to improve initiation of tuberculosis preventive therapy and increase tuberculosis treatment success in Peru: a household-randomised, controlled evaluation

Author

Wingfield, Tom, Tovar, Marco A, Huff, Doug, Boccia, Delia, Montoya, Rosario, Ramos, Eric, Datta, Sumona, Saunders, Matthew, Lewis, James J, Gilman, Robert H, and Evans, Carlton A

Abstract

For the first time in the modern era of tuberculosis control, the WHO's End TB strategy specifically integrates socioeconomic support for people affected by tuberculosis with existing biomedical interventions. However, there is little evidence of the impact of this approach on tuberculosis outcomes. We designed and implemented one of the world's first tuberculosis-specific socioeconomic support interventions, assessed its impact on tuberculosis prevention measures and treatment success, and refined the support for use in the Community Randomized Evaluation of a Socioeconomic Intervention to Prevent Tuberculosis (CRESIPT) project.
