1/9 Identification of "meaningful change" is a key area when working w patient-reported outcomes. Nevertheless, this seems to be another area of applied #psychometrics / #statistics where rituals may have replaced understanding & deliberate practice.

2/9 w QLR's special issue on "Methodologies & Considerations for Meaningful Change" (under #peerreview) we wanted to initiate a more deliberate approach, now rolled out to any paper submitted aiming to make a methodological contribution to this area👇

3/9 An area of concern are discussions around different indices, in particular for classifying intra-individual change: depending on interpretation/ use case, they are all likely not appropriate as they are based on between-indiv variation.
Progress is then not even incremental.

Your personal details will not be required - just basic demographic on gender and age. Report pdf can be downloaded after completing the test. Time needed: 5 mins.
Basic factors used are the 5 from the FFI. Statistically Valid tool, tried and tested, strong construct validity.

Don't over analyse the report. Take what's useful for u fm in there. There r strong correlations of some of the factors from the 5 to propensity for affective disorders - but those are indicative AND NOT CLINICAL. So restrict the interpretation to propensities [not diagnostics]
Here's my internship paper with Francis Tuerlinckx on #measurement/#psychometrics of affect & #ESM using graded-response #IRT.
The main finding:
The state & trait latent constructs of affect—contrary to the common belief—are essentially different.

Nonergodicity has been heavily ignored in psychology. In the intro we give an extensive historical overview of how this has troubled our idiographic (person-centered) and nomothetic (~individual differences) understanding in psychology—and the way people have tried to fix it.

In #ESM, sum-scores of PANAS-like positive & negative items are used as constructs of affect—but is that a valid decission?
To account for non-normality (& to allow nonlinearity & check latent nonmonotonicity), we used graded-response item response theory for factor analysis.

Last year, @NIMH_RDoC @NIMH commissioned a report from us @McLeanHospital (w/ @DanielGDillon @JustinBakerMD @laurenrutterr) re digital cognitive assessments for field test use, from >300k TestMyBrain participants. That report is now available! psyarxiv.com/dcszr/
Key findings: First, (1) *RELIABILITY IS A MAJOR ISSUE*, particularly for tasks from basic science / experimental traditions, built for detecting within person diffs and where reliability for between person is rarely reported. #psychometrics <- probably not trending
Second, (2) measures of negative valence / emotion (e.g. threat processing) and positive valence (e.g. reward sensitivity) usually not built for large-scale mobile assessment: technically, psychometrically, or re engagement - important for projects like @AllofUsResearch
