Health-promoting lifestyle in cardiac patients: The mediating role of cognitive flexibility in the relationship between intimate relationships and distress tolerance.

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
backgroundThe present study aimed to determine the predictive model of health-promoting lifestyle in cardiovascular patients based on intimate relationships and distress tolerance, mediated by cognitive flexibility.
methodsThe research design was a cross-sectional correlational study using structural equation modeling. The statistical population included cardiovascular patients in 2025 who referred to three specialized cardiology clinics for outpatient examination. A total of 265 individuals were selected as the sample using convenience sampling. Standard questionnaires for health-promoting behaviors (Walker et al.), social intimacy (Miller and Lefcourt), distress tolerance (Simons and Gaher), and cognitive flexibility (Dennis and Vander Wal) were used. Statistical data analysis was performed using the Pearson correlation coefficient and path analysis with bootstrap testing, employing AMOS 24 and SPSS 26 software.
resultsThe results of path analysis and bootstrap testing showed that the proposed model had a good statistical fit (χ²/df = 2.94, RMSEA = 0.071, CFI = 0.939, GFI = 0.990). The indirect effect of intimate relationships on health-promoting lifestyle through cognitive flexibility (β = 0.1148, p = 0.001) and the indirect effect of distress tolerance on health-promoting lifestyle through cognitive flexibility (β = 0.0924, p = 0.001) were confirmed.
conclusionThe structural model, with good fit, explained the mediating role of cognitive flexibility in the relationship between intimate relationships and distress tolerance with health-promoting lifestyle in cardiovascular patients. These findings provide an operational framework for psychotherapy interventions based on strengthening distress tolerance and interpersonal relationships to improve cardiovascular health.
