概要	A genogram is a graphical map of a family across at least three generations that uses standardized symbols to record its structure, key biographical and medical events, and the quality of relationships among members. Genogram analysis is the practice of constructing such a map with a client and then interpreting it to reveal intergenerational patterns — of illness, relationships, roles, conflict, and resilience — that shape the presenting situation. Standardized by Monica McGoldrick and Randy Gerson and grounded in Bowen family-systems theory, it is a staple qualitative assessment tool in social work and family therapy.	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.
