This dynamic, while necessary, risks relegating the essence of care: humanization and the therapeutic relationship. This article aims to critically analyze the role of nursing in the care of people with addictions, highlighting the importance of humanized care in highly vulnerable contexts.</p> Ursula Elisa Elias Bravo Copyright (c) 2026 Revista Internacional de Investigación en Adicciones https://creativecommons.org/licenses/by-nc/4.0 2026-09-04 2026-09-04 12 2 10.28931/riiad.2026.455 https://riiad.org/index.php/riiad/article/view/442 <p><strong>Introduction:</strong> family structure and parental monitoring styles have been identified as relevant factors associated with adolescent substance use.<br /><br /><strong>Objective:</strong> to examine the associations among family structure, parental monitoring styles, and substance use among Mexican adolescents, as well as to evaluate the mediating role of parental monitoring using structural equation modeling.<br /><br /><strong>Method:</strong> a cross-sectional study was conducted with a non-probabilistic sample of 3,572 upper secondary school students from eleven Mexican cities. Structural equation modeling was used to analyze the direct and indirect relationships among family structure, parental monitoring styles, and substance use. Family structure was recoded into dummy variables using nuclear families as the reference category.<br /><br /><strong>Results:</strong> adolescents from single-parent, reconstituted, and extended families reported lower levels of parental rule-setting (<span class="CharOverride-3" lang="es-ES">β = -.25, β = -.41, and β = -.52, respectively) and parental supervision (β = -.37, β = -.40, and β = -.76, respectively). Only single-parent families showed a significant association with higher levels of parental coldness-rejection (β = .27, <span class="CharOverride-6">p &lt; .001). Parental supervision was negatively associated with both licit (β = -.03) and illicit substance use (β = -.03), whereas parental coldness–rejection was positively associated with licit (β = .02) and illicit substance use (β = .01). Indirect effects suggested a partial mediating role of parental monitoring in the association between family structure and adolescent substance use.<br /><br /><strong>Discussion and conclusions:</strong> the findings highlight that specific parental monitoring styles are significantly associated with adolescent substance use. These results underscore the importance of family-based prevention strategies aimed at promoting consistent supervision, clear rule-setting, and positive parent-adolescent relationships.</span></span></p> Bertha L.

The study used the short version of the Internet Gaming Disorder Scale (IGDS9-SF), the Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS), and the Passion Scale. A mediation model was tested regarding the influence of passion on the association between basic psychological needs satisfaction and frustration and PVG.<br /><br /><strong>Results:</strong> results show that obsessive passion has a mediating effect on the indirect impact of autonomy frustration and competence frustration on PVG.<br /><br /><strong>Discussion and conclusions:</strong> the findings suggest that the frustration of certain basic psychological needs may lead to PVG, and if the person also develops an obsessive passion toward games, a maladaptive usage pattern may emerge.</p> Sebastian Risco Silvana Romero Saletti Copyright (c) 2026 Revista Internacional de Investigación en Adicciones https://creativecommons.org/licenses/by-nc/4.0 2026-09-04 2026-09-04 12 2 10.28931/riiad.2026.446
