Background/Objectives: Interparental conflict, with its multiple dimensions, represents a risk factor for youth mental health, triggering a series of cascading processes. Despite recent evidence highlighting that psychological inflexibility is a risk factor for adolescents’ psychopathology after stressful events, a limited number of studies have investigated its role in family conflicts. This study aims to investigate whether psychological inflexibility mediates the impact of conflict characteristics (intensity, frequency, and resolution) and threat appraisal of interparental conflict on the psychological difficulties of adolescent offspring. Methods: A sample of 195 adolescents aged between 15 and 19 years old completed the Children’s Perception of Interparental Conflict Scale, the Strengths and Difficulties Questionnaire, and the Avoidance and Fusion Questionnaire for Youth on Google Forms. Results: The findings revealed that adolescents living in a family environment characterized by high levels of perceived interparental conflicts exhibit a wide spectrum of psychological difficulties, either emotional or behavioral, partially mediated by their psychological inflexibility. However, when conflict between parents is interpreted as threatening, adolescents’ inflexibility appears to mediate the relationship between conflict and psychological difficulties. Conclusions: While future studies are needed to better understand this association, psychological flexibility might represent a relevant treatment target in adolescents exposed to interparental conflict.

Tic disorders (TDs) are neurodevelopmental conditions which affect 0.3–0.9% of individuals aged < 18 years. Although tics often improve or resolve spontaneously over time, treatment is often recommended. Pharmacological approaches are widely used as primary interventions. However, their side effects encouraged the development and the interest in nonpharmacological approaches, whose efficacy in pediatric populations remains poorly understood. This systematic review aimed to evaluate the efficacy of nonpharmacological treatments for children and adolescents with TDs. A literature review was performed using PubMed, EBSCOhost, and JABA databases up to 16 May 2024. Eligible articles were randomized controlled trials, written in English and published in peer-reviewed journals, investigating the efficacy of nonpharmacological treatments in pediatric populations diagnosed with TDs. Significant evidence supported the efficacy of behavioral interventions such as the Comprehensive Behavioral Intervention for Tics (CBIT), its reduced version the Habit Reversal Therapy (HRT), and the Exposure and Relapse Prevention (ERP) in reducing tics and tic-related impairment among young people, as assessed through the Yale Global Tic Severity Scale. Behavioral interventions were generally effective in reducing tics, although some studies reported higher effects on motor tics when compared to vocal tics. High level of efficacy was observed for both face-to-face and online treatments. While future studies are needed to improve treatment effects, especially on vocal tics, as well as to have a better understanding of treatment components and modalities, taken together, the present findings support the use of nonpharmacological intervention for TDs in youth.
