A longitudinal network analysis of pain, psychological processes and psychological and sexual distress in women with endometriosis.
Article in British journal of health psychology, 2026. 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
objectivesPrevious studies in endometriosis have linked the experience and impact of pain to psychological distress and sexual dysfunction. However, little is known about how these factors interact over time or how underlying cognitive-emotional processes contribute to their complex interconnections.
designThis study followed a Longitudinal Network Approach and explored the interconnections over time between pain (intensity and impact), psychopathological symptoms, sexual distress, and cognitive-emotional processes (cognitive fusion and difficulties in emotion regulation) in adult women with endometriosis.
methodsData was collected in a sample composed of N = 210 Portuguese cisgender women with endometriosis in a three-wave online assessment spanning 12 months.
resultsUsing multilevel vector autoregressive network analysis, results showed significant temporal pathways in which pain intensity and pain impact predicted future increases in cognitive fusion, depression, and somatization, indicating a directional cascading effect of physical symptoms on psychological processes. Higher sexual distress over time was associated with decreases in cognitive fusion. Results also found strong positive associations among pain, anxiety, depression, and somatization at each time point, as well as between-subjects asymmetrical relationships, with anxiety and somatization more strongly predicting sexual distress than the reverse.
conclusionsOverall, these findings highlight the importance of targeting transdiagnostic cognitive-emotional processes in interventions to improve pain, mental health, and sexual outcomes in women with endometriosis.
