Designing Experiments for Triadic Interventions

Evaluate and prioritize manipulable factors (e.g., activity types, communication protocols, disclosure levels) based on expected effect size and feasibility.

Design a within-triad factorial experiment to study the effects of lifestyle activities and communication strategies on jealousy and guilt.

Design a between-triad experiment comparing different jealousy and guilt management strategies across multiple triads.

Construct appropriate randomization schemes for within-triad and between-triad experimental designs.

Conduct a power analysis to determine the required sample size for detecting actor, partner, and relationship effects in a triadic experiment.

Integrate ethical considerations (e.g., consent, privacy, coercion) into the experimental design protocol.

Evaluate the trade-offs between experimental control and ecological validity when designing studies on intimate relationship behaviors.
