A dyadic stress induction tool for experimental investigation of adult patients with cancer and their family caregivers.
Article in Annals of behavioral medicine : a publication of the Society of Behavioral Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMedical illnesses are major stressors not only for the patients but also for their family caregivers, yet existing tools are inadequate to assess mechanistic response patterns to such stressors. PURPOSE: We sought to validate a stress induction task that pertains to close relationships and health-related concerns with adult patients with cancer and their family caregivers.
methodsPatients newly diagnosed with colorectal cancer (n = 123, 56 years old, 34% female, 60% Hispanic, 6.5 months post-diagnosis) and their family caregivers (55 years old, 66% female, 59% Hispanic) underwent an experimental session during which both individuals imagined a scenario where one person is hit by a car (patient) and the partner (caregiver) has no means to provide or seek out help for the victim. The session consisted of 6 phases: baseline, scenario provision, speech preparation, speech by caregiver, speech by patient, and recovery.
resultsResults of general linear modeling with repeated measures revealed that the task induced significant affective, stress, and cardiovascular responses in both patients and caregivers. Stress reactivity and recovery patterns, however, varied by patients versus caregivers, stress induction phases, and the types of assessment.
conclusionsFindings suggest the newly developed stress task as an acceptable tool for studying stress regulation in medical and family contexts. With further validation, this tool may help identify psychological and physiological pathways to improve the stress coping outcomes of adult patients with cancer and their family caregivers.
