Background: The use of technology in psychological treatments can bring evidence-based interventions closer to more people using fewer resources. The aim of this systematic review and preliminary meta-analysis was to summarize all the available information about technology-supported psychological treatments for Adjustment Disorder (AjD) patients of all ages., Method: Eligibility criteria included studies that tested a technology-supported treatment in patients with AjD and reported data on a mental health outcome. Case studies and case series were excluded. Searches were conducted in the PubMed, Web of Science, Scopus, and PsycINFO databases. Study quality was assessed using the Cochrane RoB 2.0. tool for Randomized Controlled Trials (RCTs) and the NHLBI tool for pre-post studies., Results: Nine articles (8 RCTs and 1 pre-post study) were included, eight that tested computerised interventions and two that used virtual reality. The meta-analysis showed the superior efficacy of the intervention groups compared to control conditions in reducing mental health symptomatology and a significant improvement between pre- and post-treatment., Limitations: The small number of studies included and the high heterogeneity among them were two of the main limitations., Conclusions: These results are similar to those observed in previous systematic reviews on technology-supported treatments for other mental disorders and suggest that these interventions could be effective for patients with AjD. However, further research is needed to determine the advantages and disadvantages of these interventions for the treatment of AjD in different age populations such as children, adolescents or older adults, as well as effective means for improving treatment retention., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Background: The four-item Patient Health Questionnaire-4 (PHQ-4) is a widely used screening measure for depression and anxiety., Objectives: This study aimed to test factor structure and measurement invariance in an adult sample of the general population across seven European countries., Method: A total sample of 9230 adults, 71.3 % female, M age  = 44.35 (SD = 14.11) from seven countries (Austria, Croatia, Georgia, Germany, Lithuania, Portugal, and Sweden) participated in the study. We applied confirmatory factor analysis (CFA) to examine the factor structure and measurement invariance testing to evaluate measurement equivalence across countries, gender, and age groups., Results: The CFA yielded that a two-factor PHQ-4 model with separate depression and anxiety factors had the best fit. Partial scalar measurement invariance was established across different groups based on gender, age, and country., Conclusions: The PHQ-4 is a valid and reliable measure that can be applied to screen for depression and anxiety in the general population., Limitations: The limitation of the study includes the sampling, which resulted in the sample structure with the majority of females, predominantly of high education and from urban communities., Competing Interests: Declaration of competing interest None., (Copyright © 2023 Elsevier B.V.

Background: The recently released 11th edition of International Classification of Diseases (ICD-11) included new definitions of disorders specifically associated with stress. Complex post-traumatic stress disorder (CPTSD) was included in ICD-11 as a new trauma-related disorder which could develop following prolonged or reoccurring traumatic experiences. Research on ICD-11 PTSD and CPTSD validity and epidemiology has, so far, mostly been conducted in adult population. This is the first study to explore the construct validity of the Child and Adolescent version of International Trauma Questionnaire (ITQ-CA) as a measure of ICD-11 CPTSD symptoms., Methods: The study was based on a sample of 932 adolescents from the general population aged 12-16 (M = 14.25, SD = 1.27) years exposed to various traumatic experiences. We used confirmatory factor analysis (CFA) and latent class analysis (LCA) to test validity of the ITQ-CA scores from adolescents., Results: The best fitting measurement model included six correlated factors representing the three PTSD and three DSO symptom clusters. LCA analysis revealed four classes whose symptom profiles were reflective of 'CPTSD', 'PTSD', 'DSO only', and 'Baseline'., Conclusions: Findings of the study provide support for the construct validity of the ICD-11 PTSD and CPTSD among adolescents., Competing Interests: Declaration of Competing Interest The authors report no conflicts of interest in this work., (Copyright © 2020 Elsevier B.V.
