Zusammenfassung	Goal Attainment Scaling (GAS) is a method for measuring the outcomes of an individualized intervention by writing, in advance, a small set of client-specific goals and defining for each a graded scale of possible outcomes from much worse than expected to much better than expected. After the intervention, the actual outcome on each goal is scored on this scale and the scores are combined into a single standardized index, allowing idiosyncratic, personally meaningful goals to be aggregated and compared across clients and programs. It was introduced by Thomas Kiresuk and Robert Sherman in 1968 to evaluate community mental health programs.	A single-system design is a time-series approach to evaluating practice in which a single client system — an individual, family, group, or organization — is measured repeatedly on a clearly defined target before and during (and sometimes after) an intervention. By tracking the same system over time rather than comparing a treatment group to a control group, it lets a practitioner judge whether their own intervention is associated with change in the people they actually serve. It is the methodological backbone of the 'accountable professional' tradition codified by Bloom, Fischer, and Orme.	Strengths assessment is a structured way of assessing a client that deliberately foregrounds capabilities, resources, and aspirations rather than deficits and problems. Grounded in the strengths perspective articulated by Dennis Saleebey and operationalized in Charles Rapp and Richard Goscha's strengths model, it surveys the client's life domains — such as daily living, health, finances, relationships, leisure, and spirituality — to record what is already working, what the person wants, and the personal and environmental resources available to get there. Those strengths then become the raw material for goal-setting and intervention.
