Background: Ghosting, the sudden cessation of communication without explanation, is a growing phenomenon in digital interactions. Objective: This study translated and validated the Ghosting Questionnaire (GHOST) into French to address the lack of a culturally appropriate tool for French-speaking populations. Methods: Using a cross-sectional design, we followed rigorous translation protocols, including forward and back translation, expert review, and pilot testing. A diverse group of 274 French-speaking adults participated in a multisite study in Bahrain and Tunisia by completing the French language GHOST and the Romantic Ghosting Scale (RG-C). Results: Psychometric analyses revealed strong reliability (Cronbach’s α = 0.880, test–retest ICC = 0.920) and a unidimensional structure (CFI = 0.963, RMSEA = 0.058). Convergent validity was confirmed through significant correlations with RG-C subscales: Role of Aggressor (r = 0.899), Role of Victim (r = 0.829), and Emotional Impact (r = 0.632, all p < 0.001). Item response theory analysis demonstrated proper category functioning and meaningful item hierarchy across ghosting severity levels. Conclusions: The French GHOST offers a robust instrument for researchers and clinicians to explore ghosting’s psychological impacts in French-speaking communities.

The rapid digitalization of healthcare has led to the widespread availability of mobile health (mHealth) applications, including those aimed at mental health and well-being. The present study followed the PRISMA guidelines and systematically reviewed English and/or German mental health apps available in the Google Play Store to evaluate their functional quality and behavior-change potential. It utilized the Mobile App Rating Scale (MARS) to assess app quality, including engagement, functionality, esthetics, and information quality, and the App Behavior Change Scale (ABACUS) to evaluate the potential for behavior change by inclusion of behavior change techniques (BCTs). A total of 77 apps were reviewed, with findings indicating an average functional quality and moderate behavior-change potential, as the reviewed apps only utilized a limited amount of BCTs. Notably, only a small fraction of apps had been evaluated in randomized controlled trials (RCTs). Further analysis showed that MARS and ABACUS scores had limited predictive power regarding app popularity as measured by stars awarded by users and number of user ratings in the Google Play Store. The study highlights the need for more rigorous testing of mHealth apps and suggests that factors beyond those measured by MARS and ABACUS may influence app popularity. In addition to the scientific value, this review provides insights for both users interested in mental health support via apps and developers aiming to enhance the quality and impact of mental health applications.

Autism spectrum disorder (ASD) and intellectual disability (ID) frequently coexist and share heterogeneous cognitive manifestations, yet their specific performance patterns on Wechsler scales remain poorly systematized. This meta-analysis synthesized data from 31 studies using the WISC-IV, WISC-V, WAIS-III, and WAIS-IV to compare cognitive index profiles in individuals with ASD, ID and ASD+ID. Standardized mean differences (Hedges’ g) were calculated using random-effects models, adopting a normative reference of mean 100 and SD 15. Results showed a distinct profile for ASD, with greater impairments in the Processing Speed Index (PSI) and Working Memory Index (WMI), while the Vocabulary Comprehension Index (VCI), Perceptual/Fluid Reasoning Index (PRI/FRI), and Visual Processing Index (VPI) remained close to normative scores. In contrast, ID and ASD+ID exhibited generalized deficits across all indices, with the lowest scores in Full-Scale IQ (FSIQ) and broad effects above g = −2.5. No significant differences emerged between Wechsler versions or age-based test types. Heterogeneity was high in ASD and ID across outcomes, but negligible in ASD+ID due to reduced k. These findings reinforce that ASD presents a specific cognitive pattern, whereas ID and ASD+ID display diffuse impairment, and that Wechsler scales are consistent across versions for identifying these profiles.
