Effects of Naltrexone on Repressive Coping and Disclosure of Emotional Material: A Test of the Opioid-Peptide Hypothesis of Repression and Hypertension
Bibliographic record
Abstract
Objective: The present study was designed to assess the role of endogenous opioids in the relationship of hypertension to repressive coping. Methods: Ten hypertensive and 8 normotensive males were given either the opioid antagonist naltrexone or placebo in a randomized, double-blind fashion over the course of four laboratory sessions. Measures of repression and disclosure were completed and blood pressure was assessed during a laboratory stressor protocol. Results: Opioid antagonism reduced repression and increased disclosure only in the hypertensive group. Also, opioid antagonism increased stress-related systolic blood pressure only in the hypertensive group. Conclusion: The results support the hypothesis that endogenous opioid dysregulation underlies both hypertension and repressive phenomena. DBP = diastolic blood pressure; SBP = systolic blood pressure; POMS = Profile of Mood States; LCC = Life Concerns Checklist; MAS = Taylor Manifest Anxiety Scale; MCSDS = Social Desirability Scale; TAS = Toronto Alexithymia Scale.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
