This entry reviews the uses of scales and instruments in social work practice, including scales and instruments for diagnosis and evidencing treatment necessity, as methods for monitoring client progress, and as outcomes measures of clinical significance. A resource list for locating scales and instruments is provided.

Single-system designs (SSDs) are a family of user-friendly empirical procedures that can be used to help professionals to monitor and evaluate the effectiveness of the services they provide to clients and to guide practice. SSDs can be used to evaluate interventions based on any theory or approach. Repeated measurement of the target(s) of intervention is an intrinsic and key element of SSDs. Dozens of SSDs exist, and each has its own strengths and limitations. The most basic and most widely used design is the A-B design. Data from SSDs are analyzed visually, using simple, descriptive or inferential statistics, or using criteria for practical or clinical significance.

Accurate measurement is essential for effective social work practice, but doing it well can be difficult. One solution is to use rapid assessment instruments (RAIs), which are brief scales that typically require less than 15 minutes to complete. Some are administered by practitioners, but most are self-administered on paper or electronically. RAIs are available for screening, initial assessment, monitoring of service progress, and outcome evaluation. Some require author permission, others are sold commercially, and many more are free and in the public domain. Selection of an RAI should be based first on its psychometric strength, including content, concurrent, and known-groups validity, as well as on types of reliability such as internal consistency, but practical criteria such as readability are also important. And when used in practice settings, RAIs should be part of a well-rounded measurement plan that also includes behavioral observations, client logs, unobtrusive measures, and other approaches.
Direct social work practice is the application of social work theory and/or methods to the resolution and prevention of psychosocial problems experienced by individuals, families, and groups. In this article, direct practice is discussed in the context of social work values, empowerment, diversity, and multiculturalism, as well as with attention to client strengths, spirituality, and risk and resilience influences. The challenges of practice evaluation are also considered.
