Beyond Symptom Deterioration: A Multidimensional Framework for Psychotherapy Safety

Psychotherapy safety is often inferred from good outcomes or the absence of symptom deterioration; however, deterioration constitutes only a subset of potentially harmful treatment trajectories. While reliable symptom deterioration is an important safety signal, it does not capture the full range of psychotherapy-related harm. This article distinguishes observed adverse outcomes from treatment-attributable harm, highlighting the need for safety assessment to address harms that are symptom-invisible, delayed, cumulative, relational, ethical, or that arise from failures to adapt treatment when benefit does not emerge. The Multidimensional Psychotherapy Safety Framework (MPSF) identifies seven domains of potential harm: symptomatic and functional deterioration; negative effects of the therapeutic process; relational and dependency-related harms; harms from inappropriate treatment selection or delivery; harms from therapeutic inertia; ethical and boundary-related harms; and systemic and contextual harms. Safety evaluation across these domains should consider causal attribution, temporal course, harm through commission versus omission, and visibility to conventional symptom monitoring. These dimensions are embedded within a recursive responsiveness cycle of monitoring, recognition, interpretation, response, and re-evaluation. This paper presents clinical implications and six testable propositions to guide prospective measurement, mixed-methods research, supervision, and routine safety monitoring.
