Abstract

Abstract Introduction Research has begun to identify self-efficacy as a crucial variable related to positive treatment outcomes. For treatments targeting nightmares, self-efficacy related to dreaming (DSE) has been proposed to be a key mechanism of change. Additionally, a robust amount of research exists that links nightmares to suicide, suggesting that mechanisms related to trauma-related nightmares may also be related to suicide. Thus, we sought to explore the relationship between DSE and suicide in a protocol that actively attempted to increase DSE. Methods Fifteen participants completed our Targeted Dream Incubation (TDI) protocol, which includes cueing participants for dream reports once hypnogogic sleep is detected, then after dream reports giving participants the following cue, “while you try to fall asleep, try and think of a tree”. Then after the cue is given, allowing participants to continue sleeping. The protocol included a pre-nap assessment (baseline), a 1.5-hour nap, a post-nap assessment, and a one-week follow-up assessment. In all assessments, we measured DSE. Cognitions related to suicide were measured at baseline and one-week follow-up. Non-parametric mean comparison analyses and bivariate regressions were used to analyses our aims. Results Post-nap DSE scores (t = -2.11, p < 0.05) and follow-up DSE scores (t = -1.89, p < 0.05) significantly increased after the TDI protocol. Pre-nap DSE (r = -0.59), Post-nap DSE (r = -0.66) and follow-up DSE (r = -0.74) were all significantly negatively correlated with follow-up cognitions related to suicide (p < 0.05). The change of DSE between baseline and follow-up was significantly negatively predictive of cognitions related to suicide (b = -0.24, p < 005). Conclusion Our results are the first of their kind to demonstrate the DSE is both correlated with and predictive of cognitions related to suicide. Furthermore, our results highlight that changes in DSE brought about by TDI may reduce suicidal cognitions. Future research should examine DSE, suicide, and TDI under the context of a trauma-related nightmare intervention. Although statistical power was accounted for, our small sample size was small and directly impacts generalizability. Further data collection is needed to strengthen and confirm our findings.

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.
