Which statement about combining methods is most accurate?

• A. Using multiple methods increases the risk of conflicting results.
• B. Using multiple methods provides inconsistent data.
• C. Using multiple methods can expand the evidence base and enhance interpretation.
• D. Using multiple methods is unnecessary if one tool fits all.

Answer: (C)

Using multiple methods in assessment expands the evidence base and improves interpretation. Each method brings its own strengths and limitations, so combining them allows you to cross-check findings and build a more complete picture of a client’s functioning. This approach helps you detect patterns that a single tool might miss, increases the reliability of conclusions by showing convergence across measures, and clarifies interpretations when results diverge. For instance, integrating a structured interview, standardized scales, and behavioral observations can capture different facets of symptoms, functioning, and context, leading to a more nuanced understanding. It also helps account for cultural or situational factors that a single instrument might not fully address. The other statements suggest that combining methods mainly creates conflict, inconsistency, or unnecessary work, which doesn’t align with how triangulation enhances validity and interpretation when used thoughtfully and with alignment to the referral question.
