Abstract

fetched live from OpenAlex

OBJECTIVE: Two recent randomized double-blind placebo controlled clinical trials of interferon beta-1a in multiple sclerosis have obtained hopelessness ratings using the Beck Hopelessness Scale (BHS). One of these studies, the PRISMS trial, evaluated interferon beta-1a in relapsing remitting multiple sclerosis (RRMS). Another, the SPECTRIMS trial, evaluated the same medication in secondary progressive (SP) MS. The objective of this analysis was to compare levels of hopelessness in persons with RRMS and SPMS, and to describe changes over time in the clinical trial participants. METHOD: Raw data from each clinical trial was obtained from the sponsor of the trials (Serono). Median BHS ratings, and the proportions at or above the BHS cut-point of 10 were calculated over a two (PRISMS) or three (SPECTRIMS) year period. RESULTS: The analysis included n = 532 clinical trial participants. Ratings of hopelessness were higher in SPMS clinical trial participants (SPECTRIMS) than in the RRMS group (PRISMS) at baseline (Fisher's exact test, p = 0.0035). Furthermore, ratings of hopelessness were higher during follow-up than at baseline, in the SPMS group (McNemar's exact probability,p = 0.0015), but not in the RRMS group (McNemar's exact probability,p = 0.65). Depression was strongly associated with hopelessness in both RRMS (z = 4.13, p < 0.001) and SPMS (z = 5.24, p < 0.001). CONCLUSIONS: Hopelessness is associated with SPMS, and may increase over time in this group. Hopelessness may influence suicide risk in people with MS and may potentially have an impact on coping and quality of life. Additional research is necessary to define the clinical implications of hopelessness in persons with this condition.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
