# ABA Literature Review Conducting rigorous literature reviews in behavior analysis requires knowledge of the field's unique publication landscape, single-subject design methodology, and specialized synthesis methods. This skill covers the complete process from search to synthesis. ## Key ABA Journals ### Tier 1: Core Behavior Analytic Journals | Journal | Abbreviation | Focus | Impact | |---------|-------------|-------|--------| | Journal of Applied Behavior Analysis | JABA | Applied research, all populations | Flagship applied journal | | Journal of the Experimental Analysis of Behavior | JEAB | Basic research, animal and human | Foundational experimental work | | Behavior Analysis in Practice | BAP | Practitioner-focused, applied | Shorter format, practice-relevant | | The Analysis of Verbal Behavior | TAVB | Verbal behavior research | Skinnerian language analysis | ### Tier 2: Related Applied Journals | Journal | Focus | |---------|-------| | Behavioral Interventions | International ABA research | | Journal of Behavioral Education | ABA in educational settings | | Journal of Organizational Behavior Management | OBM research | | Behavior Modification | Applied behavior change | | Research in Developmental Disabilities | Developmental disability research broadly | | Research in Autism Spectrum Disorders | Autism-specific research | | Journal of Autism and Developmental Disorders | Multidisciplinary autism research | ### Tier 3: Broader Related Journals - Journal of Positive Behavior Interventions - Education and Treatment of Children - Focus on Autism and Other Developmental Disabilities - Journal of Early Intervention ## Databases | Database | Strengths for ABA | Access | |----------|-------------------|--------| | **PubMed** | Medical and clinical ABA research, MeSH indexing | Free | | **PsycINFO** | Psychology and behavior analysis, controlled vocabulary | Institutional | | **ERIC** | Educational applications of ABA | Free | | **Web of Science** | Citation tracking, impact metrics | Institutional | | **Scopus** | Broad coverage, citation analysis | Institutional | | **Google Scholar** | Broadest coverage, pre-prints, gray literature | Free | ## Building Search Strategies ### PICO Framework Adapted for Single-Subject Research | Component | Standard PICO | Adapted for ABA | |-----------|--------------|-----------------| | **P** (Population) | Patient population | Participant characteristics (age, diagnosis, setting) | | **I** (Intervention) | Treatment | Independent variable (specific ABA procedure) | | **C** (Comparison) | Comparator | Baseline, alternative treatment, control condition | | **O** (Outcome) | Outcome measure | Dependent variable (behavior, skill, performance) | ### Example Search Research question: "What is the evidence for functional communication training (FCT) in reducing aggression in children with autism?" - **P**: (child* OR pediatric OR "autism spectrum disorder" OR ASD) - **I**: ("functional communication training" OR FCT) - **C**: (baseline OR "treatment as usual" OR "differential reinforcement") - **O**: (aggression OR "problem behavior" OR "challenging behavior") ### Boolean Operators - **AND**: Narrows results. All terms must be present. - **OR**: Broadens results. Any term can be present. Use for synonyms. - **NOT**: Excludes terms. Use sparingly to avoid losing relevant results. - **Quotation marks**: Exact phrase search. - **Asterisk (*)**: Truncation/wildcard. "reinforce*" captures reinforcement, reinforcer, reinforcers. ### Search Tips - Start broad, then narrow. - Search multiple databases—no single database captures all ABA literature. - Check reference lists of key articles (backward chaining). - Check "cited by" for key articles (forward chaining). - Set up alerts for new publications matching your search terms. ## Screening and Selecting Studies ### Inclusion/Exclusion Criteria Define before screening: - **Population**: Age range, diagnosis, setting. - **Intervention**: Must be the specific procedure of interest. - **Design**: Single-subject experimental designs (exclude case studies, AB-only designs without replication). - **Outcome**: Must measure the behavior of interest. - **Publication type**: Peer-reviewed journal articles (exclude dissertations, conference presentations unless conducting a comprehensive review). ### Screening Process 1. **Title/abstract screen**: Quick pass to exclude obviously irrelevant articles. 2. **Full-text review**: Read remaining articles fully against inclusion criteria. 3. **Decision documentation**: Record reasons for exclusion. 4. **PRISMA flowchart**: Document the number of articles at each stage. Use PRISMA for single-case extensions where available. ## Evaluating Single-Subject Research Quality ### What Works Clearinghouse (WWC) Standards for Single-Case Designs - Minimum of 3 data points per phase. - Minimum of 3 demonstrations of effect (replications). - Experimental design that allows at least one demonstration of effect. ### Quality Indicators (Horner et al., 2005) - **Participants and setting**: Described with sufficient detail for replication. - **Dependent variable**: Operationally defined, measured repeatedly, IOA reported. - **Independent variable**: Described with replication precision, fidelity measured. - **Baseline**: Stable, predictable pattern established before intervention. - **Experimental control**: At least 3 demonstrations of effect at 3 different time points. - **Social validity**: Clinical or social significance addressed. - **External validity**: Replicated across participants, settings, or behaviors. ## Synthesizing Findings ### Narrative Synthesis - Organize findings by theme, population, intervention variant, or outcome. - Describe the range of effects observed across studies. - Note moderating variables: what conditions produce stronger or weaker effects? - Identify gaps in the literature. - Summarize the strength of evidence using a system (e.g., strong, moderate, limited, insufficient). ### Quantitative Synthesis for Single-Subject Research - **PND (Percentage of Non-overlapping Data)**: Simple but limited. Sensitive to outliers. - **PEM (Percentage Exceeding the Median)**: More robust than PND. - **Tau-U**: Controls for baseline trend. Provides a p-value. - **Hedges' g or standardized mean difference**: Used in some meta-analyses but requires assumptions about distributional properties. - **Bayesian methods**: Emerging approaches for single-subject meta-analysis. ### Effect Size Interpretation | Metric | Small | Medium | Large | |--------|-------|--------|-------| | PND | <50% | 50–70% | >70% | | Tau-U | 0–0.20 | 0.20–0.60 | 0.60–1.00 | ## Writing the Literature Review Section ### Structure 1. **Introduction**: State the purpose and scope of the review. 2. **Search methodology**: Databases, search terms, inclusion/exclusion criteria. 3. **Results**: Organized thematically or chronologically. Summarize key findings. 4. **Discussion**: Strength of evidence, gaps, directions for future research. ### Writing Tips - Use past tense for describing what studies found. - Attribute findings to specific studies: "Smith et al. (2020) demonstrated that..." - Avoid over-generalizing from small numbers of studies. - Explicitly state the limitations of the reviewed literature. - Connect the review to the clinical or research question that motivated it. ## Key References - Horner, R.
