Research Design Standards and Guidelines

What Works Clearinghouse APA Division 12 Task Force on Psychological Interventions APA Division 16 Task Force on Evidence-Based Interventions in School Psychology National Reading Panel The Single-Case Experimental Design Scale (Tate et al., 2008) Ecological Momentary Assessment (Stone & Shiffman, 2002)
1. Experimental manipulation (independent variable; IV) The independent variable (i.e., the intervention) must be systematically manipulated as determined by the researcher Need a well-defined and replicable intervention for a specific disorder, problem behavior, or condition Specified intervention according to the Institute of Medicine’s (1994) classification system Specified intervention Scale was designed to assess the quality of interventions; thus, an intervention is required Manipulation in EMA is concerned with the sampling procedure of the study (see Measurement and Assessment table for more information)
2. Research designs
 General guidelines At least 3 attempts to demonstrate an effect at 3 different points in time or with 3 different phase repetitions Many research designs are acceptable beyond those mentioned The stage of the intervention program must be specified (see Rossi & Freeman, 1993) The design allows for the examination of cause and effect to demonstrate efficacy EMA is almost entirely concerned with measurement of variables of interest; thus, the design of the study is determined solely by the research question(s)
 Reversal (e.g., ABAB) Minimum of 4 A and B phases (Mentioned as acceptable. See Analysis table for specific guidelines) Mentioned as acceptable N/A Mentioned as acceptable N/A
 Multiple baseline/combined series At least 3 baseline conditions At least 3 different, successive subjects Both within and between subjects
Considered the strongest because replication occurs across individuals
Single-subject or aggregated subjects Mentioned as acceptable N/A
 Alternating treatment At least 3 alternating treatments compared with a baseline condition or two alternating treatments compared with each other N/A Mentioned as acceptable N/A Mentioned as acceptable N/A
 Simultaneous treatment Same as for alternating treatment designs N/A Mentioned as acceptable N/A Mentioned as acceptable N/A
 Changing/shifting criterion At least 3 different criteria N/A N/A N/A N/A N/A
 Mixed designs N/A N/A Mentioned as acceptable N/A N/A N/A
 Quasi-experimental N/A N/A N/A Mentioned as acceptable N/A
3. Baseline (see also Measurement and Assessment Standards) Minimum of 3 data points Minimum of 3 data points Minimum of 3 data points, although more observations are preferred No minimum specified No minimum (“sufficient sampling of behavior occurred pretreatment”) N/A
4. Randomization specifications provided N/A N/A Yes Yes N/A N/A
