    About a third of all marine fish in the world are caught in Small-Scale Fisheries (SSF). SSF are increasingly recognised as essential for food security and livelihoods for vulnerable and economically fragile communities globally. Although individual SSF vessels are usually perceived as having little impact on the ecosystem, the cumulative impact of gear type and number of vessels may be substantial. Bottom trawling is a common fishing method that can greatly influence the marine ecosystem by damaging the seafloor and generating high levels of discards. However, appropriate sampling coverage using on-board observer programmes to collect these data from SSF are rare, as they are expensive and pose logistical constraints. A mobile App was used to assess whether self-reporting by fishers could provide reliable fine-scale information on fishing effort and discards over time in an illegal shrimp trawling fishery in northern Peru. Maps depicting the spatial distribution of trawling effort and the proportion of discards from observers and fishers were compared using the Similarity in Means (SIM) Index, which ranges from 0 when spatial patterns differ completely to 1 when spatial patterns are very similar. High levels of agreement between spatio-temporal patterns of effort (SIM Index = 0.81) and discards (0.96) were found between fisher and observer maps. Moreover, far greater spatial coverage was accomplished by fishers, suggesting that self-reporting via an App represents a useful approach to collect reliable fisheries data as an initial step for effective monitoring and management of these fisheries.

    Recent scientific literature shows evidence that social media addiction negatively impacts people's mental health. In this sense, network models offer a methodological framework that naturally allows the study of mental health disorders' complexity. Therefore, the study aims to study the psychometric properties of CARS-R from the perspective of psychometric networks. A sample of 1,719 adults of both sexes (38.3% men and 61.7% women) between the ages of 18 and 59 years (M = 21.9; SD = 6.13) was collected. The EGA analysis showed that the items form a single community composed of nine nodes with large network loading values (>.35). The UVA analysis showed that all items are relevant to the network. Evidence was also found on the reliability of the scale, where the items are stable and systematically organized into a single community 100% of the time. Furthermore, bootEGA analysis showed that CARS-R is invariant across sex, age, and hours of use. The nodes were also found to have positive relationships, and the centrality index identified nodes C2, C9, and C7 as the most influential in terms of strength. A new definition of the construct is proposed based on the results found. It is concluded that the results of this study show solid evidence of the functioning of CARS-R and allow us to propose a new definition of social media addiction.

    BACKGROUND: Depression and anxiety are two of the most prevalent and disabling mental disorders worldwide, both in the general population and in outpatient clinical settings. OBJECTIVE: This study aimed to analyze the psychometric properties of the Patient Health Questionnaire-4 (PHQ-4) based on network analysis metrics. METHODS: A total of 911 Paraguayans (23.71% women and 76.29% men; mean age 31.25 years, SD = 10.63), selected by non-probabilistic convenience sampling, participated in the study. Network analysis was used to evaluate the internal structure, reliability, and measurement invariance between men and women. RESULTS: The results revealed that the PHQ-4 is a unidimensional measure through Exploratory Graph Analysis (EGA). Reliability, through structural consistency, identified that 100% of the time, only a single dimension was obtained, and all items remained stable, as they were always replicated within the empirical dimension. The unidimensional structure has shown evidence of configural invariance; therefore, the network structure functioned equally among the different sex groups. CONCLUSION: The PHQ-4 presented optimal preliminary evidence of validity based on its internal structure, reliability, and invariance between sexes. Therefore, it may be useful as an accurate and brief measure of anxiety and depressive symptoms in the Paraguayan context.

    Global drug use has increased substantially in recent years, accompanied by a rise in substance use disorders and related mental and behavioral conditions. Although the Drug Abuse Screening Test (DAST-10) has shown adequate psychometric properties in various countries, no validated version is currently available for the Peruvian clinical context, highlighting the need for robust psychometric tools to assess substance abuse. Therefore, this study aimed to evaluate the psychometric properties of the DAST-10 within the Peruvian context through a network psychometric approach. The sample included 212 service users at addiction rehabilitation centers (159 men and 53 women; mean age = 29.1 years, SD = 9.5), selected by non-probabilistic convenience sampling. Network analysis was used to evaluate the internal structure and reliability of the instrument. The Exploratory Graph Analysis showed that 5 items (1, 2, 6, 8, 9) presented a one-dimensional measure. Reliability, assessed by structural consistency, identified that one dimension was obtained 100% of the time, and items remained stable by consistently replicating within the empirical dimension. This study provides the first psychometric evidence of the DAST-10 in Peru using a network analysis approach, yielding a refined five-item version (DAST-5) with a stable one-dimensional structure, strong reliability, and alignment with DSM-5-TR criteria, highlighting its clinical relevance.

    El presente estudio tuvo como objetivo analizar la estructura interna y determinar el grado de fiabilidad del Self-Compassion Scale–Short Form (SCS-SF) en adolescentes peruanos. Para ello se contó con una muestra de 365 adolescentes de un rango de edad de 12 a 18 años (M = 15.22; DE = 1.29). Los resultados del análisis factorial confirmatorio evidencian adecuados índices de ajuste en el modelo de dos factores con correlaciones en los ítems 5,10,11 y 12(CFI = .92, TLI = .90, RMSEA = 0.062, SRMR = .060). Asimismo, los valores de fiabilidad fueron aceptables para la dimensión autocompasión(α=.71; H=.75) y autocriticismo (α=81; H=.83).Se concluye que la SCS-SF es un instrumento breve y útil que presenta adecuadas evidencias psicométricas para medir el grado de comprensión y calidez de las personas consigo mismas cuando experimentan situaciones de sufrimiento y fracaso.
