Zhrnutie	Clinical significance analysis is a method for deciding whether an individual client's change after treatment is not only statistically reliable but also meaningful in real-world terms — specifically, whether the client has moved out of the dysfunctional range and into the range typical of a functional or non-clinical population. Formalized by Neil Jacobson and Paula Truax in 1991, it combines a reliable-change criterion with a clinical cutoff to sort each client into categories such as recovered, improved, unchanged, or deteriorated, complementing group-level statistics that say nothing about individual benefit.	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.
