Abstract
Diagnostic innovations in public health are commonly evaluated through measures of technical accuracy and clinical validity. While such first-order evaluations are necessary, they offer limited insight into why diagnostic tools that perform well under controlled conditions are often unevenly adopted or resisted in psychiatric and addiction care. Implementation outcomes are strongly influenced by professional meaning-making, stigma, and contextual factors that shape how diagnostic practices are understood and enacted in everyday clinical work.
The aim of this article is to examine diagnostic innovation in psychiatric and addiction care from a second-order perspective, focusing on how diagnostic practices are experienced, interpreted, and made meaningful by clinicians. The article adopts a theory-informed qualitative review design, using phenomenography as an analytical framework to synthesize existing phenomenographic and closely related qualitative research from psychiatry, addiction care, and health services research.
The review demonstrates substantial variation in how diagnostic innovations are conceptualized in practice. Diagnostic tools may be understood as mechanisms of control and surveillance or, alternatively, as resources for dialogue, support, and patient engagement. These differences are closely linked to stigma, professional role conceptions, and organizational context. By structuring these variations into phenomenographic outcome spaces, the review highlights how diagnostic practices are embedded in dynamic configurations connecting professional understanding, patient experience, and implementation processes.
The findings suggest that the success of diagnostic innovation in psychiatric and addiction care cannot be explained by technical performance alone. A second-order, phenomenographic perspective provides critical insight into the meaning structures shaping implementation and offers a foundation for more context-sensitive educational, organizational, and policy strategies aimed at improving diagnostic innovation in complex clinical settings.
