The mediating role of self-efficacy in the association between family support and mental health among Taiwanese adolescents and youths in low-income families: a half-longitudinal mediation model.
Article in BMC public health, 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
backgroundPrevious studies have examined the correlation between social support and adolescent mental health, as well as the mediating role of self-efficacy in this association, primarily using cross-sectional data. However, few have employed longitudinal designs, considered both positive and negative aspects of mental health, or focused specifically on adolescents from financially strained families. This study aimed to investigate the mediating role of self-efficacy in the relationship between family support and both positive and negative dimensions of mental health among Taiwanese adolescents and youths from low-income families.
methodsUsing two-wave longitudinal panel data, the study included 1,792 economically disadvantaged adolescents and youths across 23 counties and cities in Taiwan. Life satisfaction and psychological distress were used to indicate positive and negative dimensions of mental health, respectively. A half-longitudinal mediation analysis was conducted.
resultsFamily support at T1 was positively associated with self-efficacy and life satisfaction but not psychological distress at T2. Self-efficacy at T1 was significantly related to life satisfaction but not psychological distress at T2. The half-longitudinal mediation analysis further supported the mediating role of self-efficacy in the association between family support and life satisfaction.
conclusionsFamily support was predictive of positive, but not negative, aspects of mental health. In addition, self-efficacy served as a mediator in the link between family support and positive mental health. These findings underscore the importance of policies and interventions that strengthen both family support and self-efficacy while also highlighting the need for differentiated approaches to address the positive and negative dimensions of mental health among adolescents and youths from low-income families in Taiwan.
