Group contingency types ABA teams may discuss are independent, dependent, and interdependent. In an independent arrangement, each member's own performance determines their outcome. In a dependent arrangement, one person or subgroup's performance determines a group outcome. In an interdependent arrangement, a combined or all-member criterion determines the group outcome. Families should ask who controls delivery, who carries risk, which supports apply, and how peer effects are monitored.
Compare group contingency types ABA uses
Write the eligible members, individual response, group criterion, observation period, outcome, and recipient for each arrangement. The same shared activity can contain different types. A group label alone cannot reveal whose performance controls access.
See the responsibility pattern
Independent arrangements preserve individual outcome control while sharing a common rule. Dependent arrangements place group access on selected members. Interdependent arrangements connect the group outcome to a combined rule. Each design can create different collaboration, privacy, blame, sabotage, and implementation risks.
Use concepts within scope
The conceptual analysis describes the three arrangements and notes that group members may add social consequences to influence one another. The BACB outline lists group-contingency procedures as examination content. Neither source selects a plan for one group.
Protect participation and communication
The Ethics Code addresses understandable communication, client involvement, consent and assent when applicable, risk, and evaluation. ASHA supports continuous AAC access. Every member needs an accessible way to understand the rule, request help, report peer effects, decline where allowed, or leave an unsafe interaction.
A practical example
A makerspace has four members. Under an independent rule, each person who returns their own tools chooses a closing activity. Under a dependent rule, everyone receives the activity if one selected member completes the check. Under an interdependent rule, all four must meet the criterion. The team compares responsibility before selecting any plan.
Questions families can use
Whose performance sets the criterion? Who receives the outcome? Can one person lose access for others? Which individual supports stay? How are peer pressure and opt-outs monitored?
