Updates of the Status Quo of Situation-Specific Theories (2015-2025)

Situation-specific theories (SSTs) have emerged as an important approach for bridging the gap between nursing theory, research, and clinical practice. Unlike grand or middle-range theories, SSTs address specific nursing phenomena within clearly defined populations or contexts. Since their introduction, SSTs have gained prominence as tools for uniting empirical evidence, patient experience, and theoretical guidance. The purpose of this article is to provide an updated synthesis of nursing SSTs published between 2015 and 2025, mapping their purposes, target populations, theorizing methods, and linkages to research and clinical practice.

A comprehensive literature search was conducted to identify SSTs published between 2015 and 2025. Five electronic databases were systematically searched using the keywords "situation-specific theory". Only peer-reviewed, English-language primary studies describing the development, testing, or application of SSTs were included. Titles, abstracts, and full texts were reviewed against inclusion criteria, resulting in 23 eligible studies. Data were extracted into a standardized table summarizing study characteristics, purposes, target populations, theorizing methods, and practice or research linkages. Findings were synthesized narratively to identify recurring themes and methodological trends in SST development, providing an integrated overview of the current state and application of SSTs.

Five overarching themes were identified across the 23 studies: (a) Broadened Scope, (b) Purpose-Driven Theorizing, (c) Dynamic Theory Lifecycle, (d) Methodological Maturity, and (e) Integration Across Practice, Education, and Research. Based on these findings, five recommendations are proposed: (a) Creative and Innovative Methods, (b) Collaborative and Interdisciplinary Development, (c) Broad Theoretical Integration, (d) Sustain Multi-Source Synthesis, and (e) Ongoing Theory Testing and Refinement.

In summary, this review demonstrates that SSTs have evolved into dynamic, context-sensitive frameworks that unite theory, research, and practice. Continued innovation, interdisciplinary collaboration, and empirical refinement will be essential to sustain their relevance and strengthen nursing's theoretical and clinical foundations.

Utilizing SSTs in clinical settings may enhance the relevance and effectiveness of care by aligning interventions with the unique needs of particular patient populations or situations.
