- Emerging evidence suggests brain white matter alterations in adolescents with early-onset psychosis (EOP; age of onset <18 years). However, as neuroimaging methods vary and sample sizes are modest, results remain inconclusive. Using harmonized data processing protocols and a mega-analytic approach, we compared white matter microstructure in EOP and healthy controls using diffusion tensor imaging (DTI). Our sample included 321 adolescents with EOP (median age=16.6 years, interquartile range (IQR)=2.14, 46.4% females) and 265 adolescent healthy controls (median age=16.2 years, IQR=2.43, 57.7% females) pooled from nine sites. All sites extracted mean fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD), and axial diffusivity (AD) for 25 white matter regions of interest per participant. ComBat harmonization was performed for all DTI measures to adjust for scanner differences. Multiple linear regression models were fitted to investigate case-control differences and associations with clinical variables in regional DTI measures. We found widespread lower FA in EOP compared to healthy controls, with the largest effect sizes in the superior longitudinal fasciculus (Cohen's d=0.37), posterior corona radiata (d=0.32), and superior fronto-occipital fasciculus (d=0.31). We also found widespread higher RD and more localized higher MD and AD. We detected significant effects of diagnostic subgroup, sex, and duration of illness, but not medication status. Using the largest EOP DTI sample to date, our findings suggest a profile of widespread white matter microstructure alterations in adolescents with EOP, most prominently in male individuals with early-onset schizophrenia and individuals with a shorter duration of illness.

Psychopharmacology in children and adolescents: unmet needs and opportunities
- 2024

Research review (peer-reviewed)abstract
- Psychopharmacological treatment is an important component of the multimodal intervention approach to treating mental health conditions in children and adolescents. Currently, there are many unmet needs but also opportunities, alongside possible risks to consider, regarding the pharmacological treatment of mental health conditions in children and adolescents. In this Position Paper, we highlight and address these unmet needs and opportunities, including the perspectives of clinicians and researchers from the European College of Neuropsychopharmacology–Child and Adolescent Network, alongside those of experts by lived experience from national and international associations, via a survey involving 644 participants from 13 countries, and of regulators, through representation from the European Medicines Agency. We present and discuss the evidence base for medications currently used for mental disorders in children and adolescents, medications in the pipeline, opportunities in the development of novel medications, crucial priorities for the conduct of future clinical studies, challenges and opportunities in terms of the regulatory and legislative framework, and innovations in the way research is conducted, reported, and promoted.

Cross-cultural adaptation, validation and reliability of the spanish satisfaction with daily occupations-occupational balance (Sdo-ob) : An evaluation tool for people with mental disorders
- 2020
-
In: International Journal of Environmental Research and Public Health. - : MDPI AG. - 1661-7827 .- 1660-4601. ; 17:23

Journal article (peer-reviewed)abstract
- Occupation can be defined as all activities that occupy a person’s time. The Satisfaction with Daily Occupations and Occupational Balance instrument evaluates the perceived satisfaction with performance and the balance in time dedicated to different occupations. The main aim was to translate the original instrument to Spanish and examine and establish the psychometric properties. This is a quantitative, cross-sectional study conducted in two stages: translation and cultural adaptation (forward translation, expert panel, back-translation, second expert panel and pre-testing and cognitive interviewing) and collecting data to evaluate psychometric properties (homogeneity, construct validity, known-groups validity, and floor/ceiling effects). One hundred participants took part in the study, adults with a diagnosis of a mental health disorder and adults without any known health problems. The Spanish version showed known-groups validity, acceptable internal consistency, and construct validity, although the relationships with some of the indicators of discriminant validity were somewhat higher than expected. The instrument shows promise as a useful screening tool for assessing activity level and satisfaction with daily occupations among a Spanish speaking population.
