Abstract
Poverty as a cultural factor affects students' school success and outcomes. In the current literature review, we aimed at providing a comprehensive analysis of intervention research designed to support school outcomes of students aged 3 to 21 years with disabilities or at risk for developing disabilities in high-poverty contexts. Eighteen studies were included in this review (16 group designs, 1 single case design, and 1 group design with embedded single case), with a total of 1782 student participants. Results indicated that most of the research studies designed for students in poverty focused on their language skills (e.g., reading, vocabulary, literacy) with various interventions. Most of the group design studies met the quality indicators (Gersten et al., 2009) with a low standard, although all single case studies met the quality indicators by higher than 80% (Kratochwill et al., 2013). As for the analysis of cultural responsiveness, we found that most studies provided limited information reflecting culturally responsive research (Trainor & Bal, 2014). Discussion and implication for practice and research are provided.
