Psychometrics of the autonomy and relatedness inventory in persons with type 2 diabetes.
Article in BMC psychology, 2025. 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
backgroundSocial support is essential for the self-management of type 2 diabetes mellitus (T2DM); no specific measure of the quality of social support has been designed and tested for people with T2DM. Having a validated questionnaire that is culturally and linguistically appropriate in this field would nurture research in this area and contribute to better patient health outcomes.
aimsThis study investigated the psychometric features of the Autonomy in Relatedness Inventory (ARI) among individuals with T2DM in Jordan. METHODOLOGY: We used a secondary dataset on self-management and outcomes of individuals with T2DM to examine the psychometric properties of the ARI. The ARI's items' overall reliability was assessed using internal consistency (Cronbach's alpha). Exploratory Factor Analysis (EFA) was used to evaluate the validity of the ARI. Confirmatory factor analysis (CFA) was performed using structural equation modeling (SEM) to test the yielded factors.
resultsThe ARI demonstrated high reliability (Cronbach's alpha value was 0.90) and validity in T2DM patients. Convergent validity of the ARI was established. The findings showed that ARI was strongly correlated with functional social support (r = .61, p < .001), in addition to negative correlations with depression (r= -.26, p < .001), anxiety (r= -.18, p < .001), and stress (r= -.24, p < .001). Regarding the factor structure of ARI, two latent factors were determined using a scree plot and EFA.
conclusionARI provides a psychometrically sound method for measuring autonomy and relatedness in T2DM patients in Jordan. CLINICAL TRIAL NUMBER: Not applicable.
