Network and Bayesian DAG Analysis of Healthy Lifestyle Beliefs, Educational Stress, and Family Relationships Among Adolescents.
Article in International journal of methods in psychiatric research, 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
backgroundHealthy lifestyle beliefs are important for adolescent health promotion, yet they are embedded within broader psychosocial contexts involving family relationships and educational stress. Although these domains are likely to interact, little is known about how their specific components are organized within a broader psychosocial system. This study examined the interrelationships among healthy lifestyle beliefs, educational stress, and family relationship quality among Bangladeshi adolescents using network analysis and directed acyclic graph (DAG) modeling.
methodsData from 501 college-attending adolescents in Bangladesh were analyzed using the Healthy Lifestyle Beliefs Scale, the Educational Stress Scale for Adolescents, and the Brief Family Relationship Scale. An undirected Gaussian graphical model was estimated to examine network structure, centrality, bridge centrality, predictability, and stability. Gender differences were assessed using the Network Comparison Test. Directed acyclic graph analyses were conducted at the subscale level to explore statistical dependency structures and edge orientations among domains.
resultsThe strongest positive edge in the network was observed between family cohesion and family expressiveness (0.520), whereas the strongest negative edge was observed between family cohesion and family conflict (-0.232). Confidence in handling problems effectively emerged as the most central node (strength = 1.325). The strongest bridge node was belief in family support for achieving goals (0.522), followed by belief in achieving personal goals and family expressiveness. Network stability was good (CS-coefficient = 0.75). Gender comparison indicated a significant difference in network structure (p = 0.003), but not in global strength (p = 0.511). DAG analyses identified dependency structures linking family relationships, educational stress, and healthy lifestyle beliefs; edge orientations were interpreted as exploratory rather than as evidence of temporal or causal ordering.
conclusionsHealthy lifestyle beliefs, educational stress, and family relationship quality were interconnected within a broader psychosocial system among adolescents. Coping-related healthy lifestyle beliefs appear central within this system, while family relational processes and academic stress showed meaningful connections with health-related beliefs. These findings may inform future longitudinal and preventive research examining coping-related beliefs alongside family communication, support, and academic stress.
