How much is enough? Considering minimally important change in youth mental health outcomes
Abstract
To make decisions in mental health care, service users, clinicians, and administrators need to make sense of research findings. Unfortunately, study results are often presented as raw questionnaire scores at different time points and regression coefficients, which are difficult to interpret with regards to their clinical meaning. Other commonly reported treatment outcome indicators in clinical trials or meta-analyses do not convey whether a given change score would make a noticeable difference to service users. There is an urgent need to improve the interpretability and relevance of outcome indicators in youth mental health (aged 12-24 years), in which shared decision making and person-centred care are cornerstones of an ongoing global transformation of care. In this Personal View, we make a case for considering minimally important change (MIC) as a meaningful, accessible, and user-centred outcome indicator. We discuss what the MIC represents, how it is calculated, and how it can be implemented in dialogues between clinician and researcher, and between youth and clinician. We outline how use of the MIC could enhance reporting in clinical trials, meta-analyses, clinical practice guidelines, and measurement-based care. Finally, we identify current methodological challenges around estimating the MIC and areas for future research. Efforts to select outcome domains and valid measurement instruments that resonate with youth, families, and clinicians have increased in the past 5 years. In this context, now is the time to define demarcations of changes in outcome scores that are clinically relevant, and meaningful to youth and families. Through the use of MIC, youth-centred outcome measurement, analysis, and reporting would support youth-centred therapeutic decision making.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
