What outcome do randomized controlled trials primarily help establish in counseling research?

• A. A descriptive snapshot of current practices.
• B. Non-experimental observations.
• C. Causality by controlling for confounding variables and bias.
• D. Personal preferences of therapists.

Answer: (C)

Randomized controlled trials are designed to determine whether an intervention causes a different outcome by making the comparison groups as similar as possible except for the intervention itself. Through random assignment, factors that could influence the outcome—whether measured or unmeasured—tend to be balanced across groups. This reduces bias and makes it more credible to say that differences in outcomes are due to the intervention rather than to other variables. In other words, RCTs provide stronger evidence of causality about whether a counseling approach produces the observed effects, assuming the study is well-designed and properly conducted. Descriptive snapshots describe situations as they exist without testing whether an intervention caused change, non-experimental observations lack randomization and are more prone to confounding, and personal preferences reflect individual therapist choices rather than evidence about outcomes.
