Association of Social Work Boards (ASWB) Clinical Practice Exam

The method described, where a social worker gathers information from multiple sources to inform a practice decision, is known as triangulation. Triangulation involves using different methods, perspectives, or data sources to gain a more comprehensive understanding of a situation or to validate findings. This approach increases the reliability and accuracy of the information collected by allowing the comparison of data from various angles, which can help to corroborate results and reduce the risk of bias associated with relying on a single source of information.

In practice, triangulation can include combining qualitative and quantitative data, utilizing various assessment tools, or consulting multiple stakeholders, which constitutes a thorough and well-rounded approach to decision-making in social work. This method is particularly valuable in complex situations where multiple factors may influence a client's circumstances and outcomes.

The other options do not fit this context. Cooptation typically refers to a process in which individuals or groups are persuaded to support a different agenda, rather than gathering diverse information. Social exchange focuses on the cost-benefit analysis of social interactions, while twinning is often associated with partnerships or collaborations, without the specific emphasis on gathering diverse data for informed decision-making. Therefore, triangulation as a process of information gathering stands out as the most appropriate method described in the question.
