18 Chapter 3 METHODS The importance of a meta-analysis of the current research regarding the demographics and correlational data on incarcerated youth receiving special education services is to provide a thorough review of what is known thus far. In addition, this analysis will lead to future studies and research to understand the key variables as well as the correlation of key factors, which are the predictors of incarcerated youth receiving special education. Further, researchers will be able to determine what educational practices should be developed to address the overrepresentation of this population within the United States juvenile correctional facilities. Design The design of this study was a descriptive, meta-analysis of the current research related to disability, incarcerated youth, and achievement. A meta-analysis is an integral way of taking current research, analyzing and drawing conclusions about the statistical data found (VandenBos, 2010). When conducting a meta-analysis, systematic steps are followed. An established list of criteria is determined, research studies are then reviewed based on the topic, the studies are then analyzed and synthesized, and finally an overall calculation of all the studies is derived and reported (Creswell, 2008). Criteria for Included Studies The first step was to determine the literature search procedures and selection criteria. Key terms were determined (see Table 1). The literature search was conducted using PsychINFO, EBSCO, and ERIC databases from 1976 to 2009. In addition to the 19 search descriptors shown in Table 1, multiple population descriptors such as: “incarcerated,” “delinquent,” and “at-risk,” were used to cross-search databases for relevant articles. More recent studies were also reviewed, by hand, in the following journals: Journal of Special Education and Journal of Correctional Education. Only studies published in recognized peer-reviewed journals were included. The studies included in the meta-analysis had to meet at least three of the four following established criteria. 1. The study sample. The sample consisted of research studies about the educational status of incarcerated male youths ranging in age from 12 to 21 years old. The participants needed to be incarcerated at the time of the study. Thus, studies that followed the progress of the youths as they re-entered society were excluded. The sample population must not have experience any long-term disruptions, such as court appearances, long stays within the infirmary, or acts, which lead to their punishment in isolation. Since the majority of the current research focuses on male incarcerated youth, no studies with female participants were included. 2. Comparison of incarcerated youth receiving special education services to incarcerated youth not receiving special education services. It is useful to compare the data of incarcerated youth receiving special education services with those incarcerated youth not receiving services in order to discover the differences for this population. Therefore, the studies included in this meta-analysis consisted of comparisons such as those mentioned on the following studies. 20 3. The type of disability. The studies included in this meta-analysis looked at the breakdown of the type of disability the incarcerated youth qualified for in order to receive special education services. 4. Correlation of specific variables and incarcerated youths receiving special education services. Since this review was to determine the extent of the role variables play on whether an incarcerated youth qualifies and receives special education within a juvenile correctional facility, studies included variables of age, ethnicity, disability, and/or academic achievement scores. Following the above criteria, seven studies were included in the analysis. (See Table 2 for the studies utilized for this meta-analysis.) Table 1 Search Terms used to Locate Literature Related to Incarcerated Youth Receiving Special Education Services Search Terms Incarcerated youth Youth At-risk Juvenile delinquency Troubled youth Special education disabilities Special education services Individual Education Plan (IEP) Mild disability Learning disability Mild/Moderate disability Academic Measures Two types of analyses were performed. First, a summary of the results of each study was conducted. Second, a descriptive analysis was conducted in order to combine 21 and analyze the relevant quantitative data from each study. The following demographic and correlational variables were examined from each of the primary studies: (a) percentage of incarcerated youth receiving special education services, (b) percentage of each special education category (c) ethnicity, (d) correlation between recidivism and cognitive abilities, (e) correlation between ethnicity and achievement, (f) correlation between category and achievement, (g) correlation between services prior and special education status, and (h) correlation between achievement and age. Data were then analyzed to provide an overall summary of the results.
