RESUMO

Background: Worldwide over a billion people live with a disability including 400,000 people in Ecuador. People with disabilities (PWD) face barriers to full participation in society. Barriers are generated by negative attitudes created through socio-cultural experiences. Awareness about disability can be facilitated through disability awareness training (DAT). Studies examining outcomes on DAT exist in high-resourced countries but are nonexistent in Ecuador. Study purposes:1) create a DAT using community input and conduct the training; 2) examine the impact of the DAT on attitudes toward and awareness of PWD; and 3) explore community perceptions regarding the impact of the DAT on action. Methods: Community-based participatory evaluation was employed to design and assess the impact of a DAT with 60 community members from Latacunga, Ecuador. The DAT incorporated a multi-modal approach (interactive discussion, problem-solving, hands-on activities) and was informed by the theory of planned behavior. Data sources were the Multidimensional Attitudes Scale (MAS) (Spanish version) administered pre- and post-DAT and interviews conducted with nine DAT participants. Results: Mann Whitney U revealed significant changes in two of four MAS constructs: emotion p = .005 and cognition p = .003. Five themes emerged from the interviews: 1) view of disability; 2) contact; 3) attitude; 4) training impact; and 5) action. Conclusion: In the short-term DAT may increase awareness of and decrease negative attitudes associated with disability. Effective strategies highlighted for raising awareness and improving attitudes were contact with PWD and education. Education leads to more positive perceptions of the barriers PWD face and their ability to participate in society.

RESUMO

PURPOSE: To develop and test decision tree (DT) models to classify physical activity (PA) intensity from accelerometer output and Gross Motor Function Classification System (GMFCS) classification level in ambulatory youth with cerebral palsy (CP) and compare the classification accuracy of the new DT models to that achieved by previously published cut points for youth with CP. METHODS: Youth with CP (GMFCS levels I-III) (N = 51) completed seven activity trials with increasing PA intensity while wearing a portable metabolic system and ActiGraph GT3X accelerometers. DT models were used to identify vertical axis (VA) and vector magnitude (VM) count thresholds corresponding to sedentary (SED) (<1.5 METs), light-intensity PA (LPA) (≥1.5 and <3 METs) and moderate-to-vigorous PA (MVPA) (≥3 METs). Models were trained and cross-validated using the "rpart" and "caret" packages within R. RESULTS: For the VA (VA_DT) and VM DT (VM_DT), a single threshold differentiated LPA from SED, whereas the threshold for differentiating MVPA from LPA decreased as the level of impairment increased. The average cross-validation accuracies for the VC_DT were 81.1%, 76.7%, and 82.9% for GMFCS levels I, II, and III. The corresponding cross-validation accuracies for the VM_DT were 80.5%, 75.6%, and 84.2%. Within each GMFCS level, the DT models achieved better PA intensity recognition than previously published cut points. The accuracy differential was greatest among GMFCS level III participants, in whom the previously published cut points misclassified 40% of the MVPA activity trials. CONCLUSIONS: The GMFCS-specific cut points provide more accurate assessments of MVPA levels in youth with CP across the full spectrum of ambulatory ability.
