A Structural Validation of the Brief COPE Scale among Outpatients with Alcohol and Opioid Use Disorders
Recovery from substance use disorder requires access to effective coping resources. The most widely self-reported questionnaire used to assess coping responses is the Brief COPE; however, different factorial structures were found in a variety of samples. This study aimed to examine across outpatients with substance use disorders the factor structure of the short dispositional French version of the Brief Coping Orientation to Problem Experienced (COPE) inventory. The French version of the Brief COPE was administered in a sample of 318 outpatients with alcohol or opioid substance use disorder. A clustering analysis on latent variables (CLV) followed by a confirmatory factorial analysis (CFA) was conducted to examine the factor structure of the scale. The internal consistency of the Brief COPE and its subscales were also studied. The analysis revealed a nine-factor structure with a revised 24-item version consisting of functional strategies (four items), problem-solving (four items), denial (two items), substance use (two items), social support seeking (four items), behavioral disengagement (two items), religion (two items), blame (two items), and humor (two items) that demonstrated a good fit to the data. This model explained 53% of the total variance with an overall McDonald’s omega (ω) of 0.96 for the revised scale. The present work offers a robust and valid nine-factor structure for assessing coping strategies in French outpatients with opioid or alcohol substance use disorder. This structure tends to simplify its use and interpretation of results for both clinicians and researchers
Validation of Generalized Anxiety Disorder 6 (GAD-6)—A Modified Structure of Screening for Anxiety in the Adolescent French Population
Anxiety disorders remain underdiagnosed and undertreated, especially in child and adolescent populations. This study aimed to examine the construct validity of the Generalized Anxiety Disorder Scale 7 (GAD-7) in a sample of French adolescents by combining the Classical Test Theory (CTT) and the Item Response Theory (IRT) and to assess the invariance of items. A total of 284 adolescents enrolled in school in the Lorraine region were randomly selected to participate in a cross-sectional study. A psychometric evaluation was performed using a combination of CTT and IRT analyses. The study of psychometric properties of GAD-7 revealed poor adequation to the sample population, and engendered the deletion of one item (#7) and the merger of two response modalities (#2 and #3). These modifications generated the new GAD-6 scale, which had a good internal consistency reliability (Cronbach α = 0.85; PSI = 0.83), acceptable goodness-of-fit indices (χ2 = 28.89, df = 9, P = 0.001; RMSEA (90% CI) = 0.088 [0.054; 0.125]; SRMR = 0.063; CFI = 0.857), and an acceptable convergent validity (r = –0.62). Only one item (#5) had a consistent Differential Item Functioning (DIF) by gender. This study evaluated the structure of the GAD-7 scale, which was essentially intended at discriminating adolescent patients with high levels of anxiety, and adapted it to a population of adolescents from the general population. The GAD-6 scale presents better psychometric properties in this general population than the original GAD-7 version

Association between increased EEG signal complexity and cannabis dependence
International audienceBoth acute and regular cannabis use affects the functioning of the brain. While several studies have demonstrated that regular cannabis use can impair the capacity to synchronize neural assemblies during specific tasks, less is known about spontaneous brain activity. This can be explored by measuring EEG complexity, which reflects the spontaneous variability of human brain activity. A recent study has shown that acute cannabis use can affect that complexity. Since the characteristics of cannabis use can affect the impact on brain functioning, this study sets out to measure EEG complexity in regular cannabis users with or without dependence, in comparison with healthy controls. We recruited 26 healthy controls, 25 cannabis users without cannabis dependence and 14 cannabis users with cannabis dependence, based on DSM IV TR criteria. The EEG signal was extracted from at least 250 epochs of the 500ms pre-stimulation phase during a visual evoked potential paradigm. Brain complexity was estimated using Lempel-Ziv Complexity (LZC), which was compared across groups by non-parametric Kruskall-Wallis ANOVA. The analysis revealed a significant difference between the groups, with higher LZC in participants with cannabis dependence than in non-dependent cannabis users. There was no specific localization of this effect across electrodes. We showed that cannabis dependence is associated to an increased spontaneous brain complexity in regular users. This result is in line with previous results in acute cannabis users. It may reflect increased randomness of neural activity in cannabis dependence. Future studies should explore whether this effect is permanent or diminishes with cannabis cessation

Measuring COVID-19 related stress and its associated factors among the parents of school-aged children during the first lockdown in France
Abstract Background The COVID-19 pandemic placed important challenges on parents, as they had to meet various demands during lockdown, including childcare, work and homeschooling. Therefore, the current study aimed to investigate perceived stress levels among the parents of school-aged children and explore their association with sociodemographic, environmental and psychological factors during lockdown. Methods A cross-sectional study was conducted among the parents of school-aged children ages 8 to 18, who lived in the Grand Est region of France during the first wave of the pandemic. An online survey collected sociodemographic data, living and working conditions, and exposure to COVID-19 as well as parent’s levels of perceived stress (PSS-10), self-perceived health status (SF-12), social support (MSPSS) and resilience (BRS). Multivariable logistic regression models were conducted to evaluate the association between moderate to severe perceived stress and various factors. Results In total, 734 parents were included. The results indicated that 47% were experiencing moderate stress and 7.2% were experiencing severe stress. Factors most strongly associated with risk of moderate to severe levels of stress were lower levels of parental resilience (OR = 3.8, 95% CI: 2.2–6.6) and poor self-perceived mental health status (OR = 7.3, 95% CI: 5.0–10.8). The following risk factors were also identified: female sex; being in the age range of 35–44; difficulties isolating and contracting COVID-19, which involved hospitalization and separation or isolation from family. The support of friends (OR = 0.8, 95% CI: 0.7–1.0) and family (OR = 0.5, 95% CI: 0.3–0.8) were protective factors. Conclusions These findings suggest that supportive and preventive programs should focus on the improvement of resilience and mental health management to promote parents’ wellbeing. Research has to focus both on individuals’ inner potential for increasing resilience and the environmental resources to be activated. Building and boosting resilience among parents could serve as a protective factor against negative outcomes for them and their families
Prognostic Value of Early Therapeutic Alliance in Weight Recovery: A Prospective Cohort of 108 Adolescents With Anorexia Nervosa
International audiencePURPOSE:To determine whether patients' perception of early therapeutic alliance (TA) could predict time to achieve a target weight among adolescents undergoing treatment for anorexia nervosa.METHOD:TA was assessed in a prospective cohort recruited from both inpatient and outpatient settings by self-administered and validated questionnaires. Kaplan-Meier survival curves were compared by log rank test, and Cox regression was used to test whether patients' perception of early TA predicted time to achieve a target weight.RESULTS:In total, 108 patients were included, and 79.6% achieved a target weight. Better patient perception of early TA increased the hazard ratio (HR) of achieving a target weight (HR = 2.7, 95% confidence interval: 1.7-4.4, p < .001) such as being in the inpatient setting by 6.7. Being very severely underweight at admission decreased the HR of achieving the target weight.CONCLUSION:Patients' perception of early TA is a good predictor of achieving a target weight. Because TA is a modifiable construct, it could be a target for intervention
The effects of living and learning conditions on the health-related quality of life of children and adolescents during the COVID-19 lockdown in the French Grand Est region
International audienceIntroduction: COVID-19 lockdown measures resulted in children and adolescents staying and learning at home. This study investigated health-related quality of life (HRQoL) and its associated factors among youth during the first lockdown. Methods: A cross-sectional study was conducted among 8-to 18-year-olds from the French Grand Est region. Sociodemographic data and information on living and learning conditions were collected using an online survey. HRQoL was assessed using the KIDSCREEN-27. Multiple regression analysis was performed to explore factors related to low HRQoL in each dimension. Results: In total, 471 children from 341 households were included. Difficulties isolating at home were associated with low HRQoL in the psychological well-being (OR = 2.2, 95% CI: 1.2-4.0) and parent relations and autonomy (OR = 2.1, 95% CI: 1.2-3.8) dimensions. Conflicts with dwelling occupants were related to increased ORs in the psychological well-being (OR = 2.9, 95% CI: 1.9-4.6), parent relations and autonomy (OR = 2.2, 95% CI: 1.4-3.4) and school environment (OR = 2.4, 95% CI: 1.5-3.7) dimensions. Living in an apartment (OR = 1.8, 95% CI: 1.1-3.1), never leaving home (OR = 2.6, 95% CI: 1.2-5.9), having indoor noise at home (OR = 2.3, 95% CI: 1.2-4.6), and having a parent with high anxiety (OR = 1.8, 95% CI: 1.1-3.1) were associated with low HRQoL in the social support and peers dimension. Children working less than 1 h/day on schoolwork had an increased OR of 3.5 (95% CI: 1.4-9.0) in the school environment dimension. Conclusion: Living and learning conditions were associated with low HRQoL among children and adolescents during the COVID-19 lockdown. Prevention and intervention programs are needed to support youth by facilitating their interactions and improving their coping and to prepare for future waves
