Group Contingency
Study: Lambert et al. (2015)

Describe how students were selected to participate in the study:

Students were selected based on their enrollment in a participating classroom. Pre-baseline observation data indicated that the classroom was exhibiting disruptive behavior in 30% of intervals.

Describe how students were identified as being at risk for academic failure (AI) or as having emotional/behavioral difficulties (BI):

The students in the classroom were not identified as having an emotional or behavioral disorder though the classrooms could be characterized as having high rates of disruptive behavior. Some of the student did have a disability

ACADEMIC INTERVENTION: What percentage of participants were at risk, as measured by one or more of the following criteria:

• below the 30th percentile on local or national norm, or
• identified disability related to the focus of the intervention?

%

BEHAVIORAL INTERVENTION: What percentage of participants were at risk, as measured by one or more of the following criteria:

• emotional disability label,
• placed in an alternative school/classroom,
• non-responsive to Tiers 1 and 2, or
• designation of severe problem behaviors on a validated scale or through observation?

Please describe the study design:

The research design combined elements of both an ABAB design and multiple baseline in which the intervention was withdrawn within and applied within each of the classroom cases and as well as with a staggered implementation across classrooms.

Clarify and provide a detailed description of the treatment in the submitted program/intervention:

The group contingency consisted of establishing a criterion goal for positive comments to be made about positive classmate behavior for their peers. If the class met the threshold, they received a reward. There was a limit on the number of positive comments that each student could submit.

Clarify what procedures occurred during the control/baseline condition (third, competing conditions are not considered; if you have a third, competing condition [e.g., multi-element single subject design with a third comparison condition], in addition to your control condition, identify what the competing condition is [data from this competing condition will not be used]):

It appears as though the instructional tasks did not vary from baseline to intervention and that the implementation of the group contingency and positive comment procedures were the only difference.

Please describe how replication of treatment effect was demonstrated (e.g., reversal or withdrawal of intervention, across participants, across settings)

The ABAB provided a sufficient number of replication attempts to evaluate the effects of the intervention. The added multiple baseline element provided another check against threats to internal validity.

Please indicate whether (and how) the design contains at least three demonstrations of experimental control (e.g., ABAB design, multiple baseline across three or more participants).

There were a total of four opportunities for the intervention effect to be demonstrated.

If the study is a multiple baseline, is it concurrent or non-concurrent?

Study measures are classified as targeted, broader, or administrative data according to the following definitions:

• Targeted measures
  Assess outcomes, such as competencies or skills, that the program was directly targeted to improve.
  • In the academic domain, targeted measures typically are not the very items taught but rather novel items structured similarly to the content addressed in the program. For example, if a program taught word-attack skills, a targeted measure would be decoding of pseudo words. If a program taught comprehension of cause-effect passages, a targeted measure would be answering questions about cause-effect passages structured similarly to those used during intervention, but not including the very passages used for intervention.
  • In the behavioral domain, targeted measures evaluate aspects of external or internal behavior the program was directly targeted to improve and are operationally defined.
• Broader measures
  Assess outcomes that are related to the competencies or skills targeted by the program but not directly taught in the program.
  • In the academic domain, if a program taught word-level reading skill, a broader measure would be answering questions about passages the student reads. If a program taught calculation skill, a broader measure would be solving word problems that require the same kinds of calculation skill taught in the program.
  • In the behavioral domain, if a program taught a specific skill like on-task behavior in one classroom, a broader measure would be on-task behavior in another setting.
• Administrative data measures apply only to behavioral intervention tools and are measures such as office discipline referrals (ODRs) and graduation rates, which do not have psychometric properties as do other, more traditional targeted or broader measures.
