The effects of an empowering self-management model on sense of coherence and self-efficacy among adolescent girls with internet addiction in Bushehr, Iran: a randomized controlled trial.

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
backgroundDespite the positive applications of the internet, excessive use and its associated harmful consequences, particularly internet addiction among adolescents, have attracted significant attention. The present study aimed to assess the effect of an empowering self-management model on the sense of coherence and self-efficacy among adolescent girls with internet addiction in Bushehr (Iran),2022.
methodsThis clinical trial was conducted on 80 adolescent girls with internet addiction in the first grade of secondary school in Bushehr. In a two-stage cluster sampling design, schools were randomly selected and assigned to either the intervention or control group. Participants voluntarily completed Young’s(1998) internet addiction test and were included in the study if they scored 46 or higher. Based on an empowering self-management model, the intervention group participated in a five-stage plan: (1) self-awareness of changes and understanding their personal level of performance and expectations; (2) optimal goal setting; (3) planning; (4) adjusting physical, psychological, and social structures; and (5) evaluation. Data collection instruments comprised the Antonovsky’s sense of coherence Questionnaire (SOC-13) and the Sherer’s general self-efficacy scale (GSES), administered at baseline and post-intervention to assess changes in sense of coherence and self-efficacy. Data were analyzed using SPSS 26.0 at the significance level of 0.05.
resultsThe two groups showed no significant differences in most demographic variables, except for age and having a personal room (p < 0.05). After adjusting for age and access to a personal room, a repeated-measures analysis of covariance(ANCOVA) revealed that the intervention group experienced a significantly greater improvement in sense of coherence than the control group (adjusted mean change:25.57 ± 1.1 vs. -2.67 ± 1.1; p < 0.001; partial eta squared [η²] = 0.799). Similarly, self-efficacy increased significantly more in the intervention group than in the control group (adjusted mean change:17.05 ± 0.76 vs. -2.77 ± 0.76; p < 0.001; η² = 0.807). After the intervention, severe internet addiction in the intervention group dropped to zero, with 10% of participants classified as mild, while no change was observed in the control group (p = 0.03). Accordingly, the mean change in the internet addiction score after the intervention was − 12.85 ± 0.79 in the intervention group and + 1.70 ± 0.28 in the control group (p < 0.001).
conclusionThe self-management empowerment model significantly improved the sense of coherence and self-efficacy among adolescent girls with internet addiction. However, given the several potential biases, short follow-up period and the homogeneity of participants, these findings should be interpreted with caution. Further studies involving male adolescents and more diverse samples are warranted to confirm the generalizability of the results.
