Net greenhouse gas balance of fibre wood plantation on peat in Indonesia.

Tropical peatlands cycle and store large amounts of carbon in their soil and biomass1-5. Climate and land-use change alters greenhouse gas (GHG) fluxes of tropical peatlands, but the magnitude of these changes remains highly uncertain6-19. Here we measure net ecosystem exchanges of carbon dioxide, methane and soil nitrous oxide fluxes between October 2016 and May 2022 from Acacia crassicarpa plantation, degraded forest and intact forest within the same peat landscape, representing land-cover-change trajectories in Sumatra, Indonesia. This allows us to present a full plantation rotation GHG flux balance in a fibre wood plantation on peatland. We find that the Acacia plantation has lower GHG emissions than the degraded site with a similar average groundwater level (GWL), despite more intensive land use. The GHG emissions from the Acacia plantation over a full plantation rotation (35.2 ± 4.7 tCO2-eq ha-1 year-1, average ± standard deviation) were around two times higher than those from the intact forest (20.3 ± 3.7 tCO2-eq ha-1 year-1), but only half of the current Intergovernmental Panel on Climate Change (IPCC) Tier 1 emission factor (EF)20 for this land use. Our results can help to reduce the uncertainty in GHG emissions estimates, provide an estimate of the impact of land-use change on tropical peat and develop science-based peatland management practices as nature-based climate solutions.

Trauma resident exposure in Canada and operative numbers (TraumaRECON): a national multicentre retrospective review of operative and nonoperative trauma teaching.

BACKGROUND: General surgeons play an important role in the provision of trauma care in Canada and the current extent of their trauma experience during training is unknown. We sought to quantify the operative and nonoperative educational experiences among Canadian general surgery trainees. METHODS: We conducted a multicentre retrospective study of major operative exposures experienced by general surgery residents, as identified using institutional trauma registries and subsequent chart-level review, for 2008-2018. We also conducted a site survey on trauma education and structure. RESULTS: We collected data on operative exposure for general surgery residents from 7 programs and survey data from 10 programs. Operations predominantly occurred after hours (73% after 1700 or on weekends) and general surgery residents were absent from a substantial proportion (25%) of relevant trauma operations. The structure of trauma education was heterogeneous among programs, with considerable site-specific variability in the involvement of surgical specialties in trauma care. During their training, graduating general surgery residents each experienced around 4 index trauma laparotomies, 1 splenectomy, 1 thoracotomy, and 0 neck explorations for trauma. CONCLUSION: General surgery residents who train in Canada receive variable and limited exposure to operative and nonoperative trauma care. These data can be used as a baseline to inform the application of competency-based medical education in trauma care for general surgery training in Canada.

Psychometric properties of the Spanish version of the Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM) in Chile.

OBJECTIVE: To examine the psychometric properties of the Spanish version of the 34-item Clinical Outcomes in Routine Evaluation-Outcome Measure questionnaire (CORE-OM). METHOD: Psychometric exploration was conducted in two samples: non-clinical (n = 706) and clinical (n = 420) participants. The non-clinical sample comprised a subgroup of community members (n = 308) and students (n = 398). The clinical sample consisted of self-reported patients (n = 209) and outpatients (n = 211). The analysis included both internal and test-retest reliability, convergent validity, and principal component analysis. A reliable change index and clinical cut-off scores were established for assessing clinically significant change. RESULTS: The Spanish CORE-OM demonstrated good internal consistency and test-retest reliability, along with satisfactory convergent validity against the 45-item Outcome Questionnaire (OQ-45.2). There were strong differentiations between the clinical and non-clinical samples and the four sample subsets. The outpatient group reported the highest scores, while the community group exhibited the lowest scores. There were no marked gender effects. All observed patterns aligned closely with the established Spanish referential data. CONCLUSION: Our findings provide support for the utilization of the Spanish CORE-OM as a measure for tracking psychotherapeutic progress in the context of Chile.

Routine Outcome Monitoring from Psychotherapists' Perspectives: A Framework Analysis Study of Expected Benefits and Difficulties.

Psychotherapists' attitudes and expectations towards routine outcome monitoring can impact the likelihood of its fruitful implementation. While existing studies have predominantly focused on Europe and North America, research in Latin America remains limited. The aim of this study is to explore therapists' expected benefits and difficulties prior to implementing a routine outcome monitoring system in a university psychotherapy service in Ecuador. An exploratory and descriptive cross-sectional qualitative study was carried out with 20 participants aged 21 to 47. Semi-structured interviews were conducted to explore participants' knowledge about routine outcome monitoring, their expectations of the difficulties, benefits, usability and risks of using a monitoring system, as well as their expectations about their role in the process. The data analysis adhered to the framework analysis methodology, leading to the identification of six overarching themes, 36 specific themes and 82 subthemes. The interviews highlighted a spectrum of positive and negative expectations at several levels: institutional/general, therapeutic process, therapists, and clients. Perceived benefits encompassed various aspects, including the availability of supplementary information, continuous adaptation of the therapeutic process, facilitation of organization and treatment planning, opportunities for professional development, and fostering patient trust and empowerment. On the other hand, anticipated difficulties comprised concerns such as discomfort among therapists and clients, increased workload, system usage and technical difficulties, and the risk of excessive quantification. Overall, participants expressed more anticipated benefits than difficulties. We present recommendations that can support and optimize the current local implementation efforts of routine outcome monitoring, both within this service and in other settings. These recommendations consider ways to meet positive expectations and address or mitigate negative ones.

Gut Microbial Perturbation and Host Response Induce Redox Pathway Upregulation along the Gut-Liver Axis during Giardiasis in C57BL/6J Mouse Model.

Apicomplexan infections, such as giardiasis and cryptosporidiosis, negatively impact a considerable proportion of human and commercial livestock populations. Despite this, the molecular mechanisms of disease, particularly the effect on the body beyond the gastrointestinal tract, are still poorly understood. To highlight host-parasite-microbiome biochemical interactions, we utilised integrated metabolomics-16S rRNA genomics and metabolomics-proteomics approaches in a C57BL/6J mouse model of giardiasis and compared these to Cryptosporidium and uropathogenic Escherichia coli (UPEC) infections. Comprehensive samples (faeces, blood, liver, and luminal contents from duodenum, jejunum, ileum, caecum and colon) were collected 10 days post infection and subjected to proteome and metabolome analysis by liquid and gas chromatography-mass spectrometry, respectively. Microbial populations in faeces and luminal washes were examined using 16S rRNA metagenomics. Proteome-metabolome analyses indicated that 12 and 16 key pathways were significantly altered in the gut and liver, respectively, during giardiasis with respect to other infections. Energy pathways including glycolysis and supporting pathways of glyoxylate and dicarboxylate metabolism, and the redox pathway of glutathione metabolism, were upregulated in small intestinal luminal contents and the liver during giardiasis. Metabolomics-16S rRNA genetics integration indicated that populations of three bacterial families-Autopobiaceae (Up), Desulfovibrionaceae (Up), and Akkermanasiaceae (Down)-were most significantly affected across the gut during giardiasis, causing upregulated glycolysis and short-chained fatty acid (SCFA) metabolism. In particular, the perturbed Akkermanasiaceae population seemed to cause oxidative stress responses along the gut-liver axis. Overall, the systems biology approach applied in this study highlighted that the effects of host-parasite-microbiome biochemical interactions extended beyond the gut ecosystem to the gut-liver axis. These findings form the first steps in a comprehensive comparison to ascertain the major molecular and biochemical contributors of host-parasite interactions and contribute towards the development of biomarker discovery and precision health solutions for apicomplexan infections.

Responsible agriculture must adapt to the wetland character of mid-latitude peatlands.

Drained, lowland agricultural peatlands are greenhouse gas (GHG) emission hotspots and a large but vulnerable store of irrecoverable carbon. They exhibit soil loss rates of ~2.0 cm yr-1 and are estimated to account for 32% of global cropland emissions while producing only 1.1% of crop kilocalories. Carbon dioxide emissions account for >80% of their terrestrial GHG emissions and are largely controlled by water table depth. Reducing drainage depths is, therefore, essential for responsible peatland management. Peatland restoration can substantially reduce emissions. However, this may conflict with societal needs to maintain productive use, to protect food security and livelihoods. Wetland agriculture strategies will, therefore, be required to adapt agriculture to the wetland character of peatlands, and balance GHG mitigation against productivity, where halting emissions is not immediately possible. Paludiculture may substantially reduce GHG emissions but will not always be viable in the current economic landscape. Reduced drainage intensity systems may deliver partial reductions in the rate of emissions, with smaller modifications to existing systems. These compromise systems may face fewer hurdles to adoption and minimize environmental harm until societal conditions favour strategies that can halt emissions. Wetland agriculture will face agronomic, socio-economic and water management challenges, and careful implementation will be required. Diversity of values and priorities among stakeholders creates the potential for conflict. Successful implementation will require participatory research approaches and co-creation of workable solutions. Policymakers, private sector funders and researchers have key roles to play but adoption risks would fall predominantly on land managers. Development of a robust wetland agriculture paradigm is essential to deliver resilient production systems and wider environmental benefits. The challenge of responsible use presents an opportunity to rethink peatland management and create thriving, innovative and green wetland landscapes for everyone's future benefit, while making a vital contribution to global climate change mitigation.

Melatonin for pre-medication in children: a systematic review.

BACKGROUND: Melatonin's effectiveness as an anxiolytic medication has been confirmed in adults; however, its efficacy in a paediatric population is unclear. A number of small studies have assessed its use in children as a pre-operative anxiolytic, with conflicting results. METHODS: We undertook a systematic review of pre-operative melatonin use in children. Four databases (MEDLINE, Embase, the Cochrane Central Register of Controlled Trials and Web of Science), and ' ClinicalTrials.gov ' were searched for ongoing and completed clinical trials of relevance. Citation tracking reference lists and relevant articles were also accessed. The review was unrestricted by comparator or outcomes. Eleven studies were judged eligible for inclusion. There were high levels of heterogeneity in melatonin administration (in terms of dose and timing). Variable outcomes were reported and included: anxiety; anaesthetic success; analgesia; sedation; post-operative recovery; and safety. Outcomes were not always assessed with the same measures. RESULTS: Evidence to support melatonin's anxiolytic properties in this setting is conflicting. Melatonin was associated with reduced sedative effects, post-operative excitement and improved emergence behaviour, compared to comparator drugs. One study reported the benefit of melatonin use on sleep disturbance at two weeks post-surgery. No adverse safety events were identified to be significantly associated with melatonin, affirming its excellent safety profile. CONCLUSION: Despite potential advantages, including improved emergence behaviour, based on current evidence we cannot confirm whether melatonin is non-inferior to current "usual care" pre-medications. Further consideration of melatonin as an anxiolytic pre-medication in paediatric surgery is needed.

Acceptability and Psychometric Properties of the Spanish Translation of the Schwartz Outcome Scale-10 (SOS-10-E) Outside the United States: A Replication and Extension in a Latin American Context.

The Schwartz Outcome Scale-10 is a 10-item measure that has proven utility for assessing well-being and mental health and measuring change over time. Although there is a Spanish translation of the measure created in the United States for the Latino population, its acceptability and psychometric properties have not been studied in unilingual Spanish speakers, nor outside the United States. The aim of the present study is to explore these properties in larger samples, clinical and non-clinical, from Latin America adding convergent validity checking and exploration of effects of gender and age on scores. A qualitative study was conducted with 11 participants to test for dialect/language issues, then a psychometric exploration of data from 886 participants in a non-clinical sample and 172 in a clinical sample. The results showed good psychometric characteristics and suggest that the SOS-10-E can be used in Latin America. A cutoff of 42.51 differentiates clinical scores from non-clinical. Future studies are needed to explore sensitivity to change and check replication in other Spanish speaking populations.

Psychological intervention change measurement in Latin America: Where from? Where to?

Objective: To conduct a scoping review of measure utilization in Latin America. We relate the findings to the needs of the region and give recommendations for measure usage in LA. Methods: Six electronic databases (PubMed, Web of Science, CINAHL, PsychInfo, SCOPUS, and SCIELO) were searched to identify peer-reviewed literature. In total, 207 studies using change and/or outcome measures were identified based on a priori inclusion criteria. Results: Production by country varied markedly; more than three quarters of the studies took place in just three of the 20 Latin American countries: Brazil, Chile, and Mexico. The most frequently used measures were the Outcome Questionnaire, Beck Depression Inventory-II, Hamilton Rating Scale, and Yale-Brown Obsessive-Compulsive Scale. The most common diagnosis was depression (n = 54). Conclusions: Outcome and change research in Latin America is growing rapidly but future efforts should focus more tightly on the needs of the region, as well as on forging collaborations with researchers from other regions. The use of change measures for serial assessment throughout interventions is recommended in view of its adaptability to highly diverse Latin American social realities. Dissemination of research findings and promotion of outcome and change measure use through implementation of public policy is recommended.

Impact of forest plantation on methane emissions from tropical peatland.

Tropical peatlands are a known source of methane (CH4 ) to the atmosphere, but their contribution to atmospheric CH4 is poorly constrained. Since the 1980s, extensive areas of the peatlands in Southeast Asia have experienced land-cover change to smallholder agriculture and forest plantations. This land-cover change generally involves lowering of groundwater level (GWL), as well as modification of vegetation type, both of which potentially influence CH4 emissions. We measured CH4 exchanges at the landscape scale using eddy covariance towers over two land-cover types in tropical peatland in Sumatra, Indonesia: (a) a natural forest and (b) an Acacia crassicarpa plantation. Annual CH4 exchanges over the natural forest (9.1 ± 0.9 g CH4  m-2  year-1 ) were around twice as high as those of the Acacia plantation (4.7 ± 1.5 g CH4  m-2  year-1 ). Results highlight that tropical peatlands are significant CH4 sources, and probably have a greater impact on global atmospheric CH4 concentrations than previously thought. Observations showed a clear diurnal variation in CH4 exchange over the natural forest where the GWL was higher than 40 cm below the ground surface. The diurnal variation in CH4 exchanges was strongly correlated with associated changes in the canopy conductance to water vapor, photosynthetic photon flux density, vapor pressure deficit, and air temperature. The absence of a comparable diurnal pattern in CH4 exchange over the Acacia plantation may be the result of the GWL being consistently below the root zone. Our results, which are among the first eddy covariance CH4 exchange data reported for any tropical peatland, should help to reduce the uncertainty in the estimation of CH4 emissions from a globally important ecosystem, provide a more complete estimate of the impact of land-cover change on tropical peat, and develop science-based peatland management practices that help to minimize greenhouse gas emissions.

Development and validation of the relational depth frequency scale.

Objective: The Relational Depth Frequency Scale (RDFS) was developed to measure the frequency of specific moments of profound contact and engagement in psychotherapy. Method: Following an initial process of item generation and rating, Three-Step Test Interviews were conducted with eight therapists and clients to further refine potential items. Sixteen relational depth items were then taken forward for psychometric assessment in an online sample of 336 therapists and 220 clients, each divided into separate "shortening" and "checking" subsamples. Results: Following psychometric scale shortening involving confirmatory factor analysis (CFA) and Rasch analysis, we formed a six item RDFS that could be used with both therapists and clients. The parameters of the shortened form replicated well in the independent checking subsamples with good internal consistency (Cronbach's α = .85 and .93 in therapist and clients respectively), acceptable fit statistics in CFA and Rasch analysis, and moderate to high levels of convergent validity against the Working Alliance Inventory (Short Form, Revised) and Relational Depth Inventory (RDI-R2). Conclusion: As a brief self-report measure, the RDFS can be used to further assess the relationship between relational depth and therapeutic outcomes. Further research is needed to examine the validity of the RDFS in clinical settings.

Human Immunodeficiency Virus Type 1 RNA Detected in the Central Nervous System (CNS) After Years of Suppressive Antiretroviral Therapy Can Originate from a Replicating CNS Reservoir or Clonally Expanded Cells.

BACKGROUND: Human immunodeficiency virus type 1 (HIV-1) populations are detected in cerebrospinal fluid (CSF) of some people on suppressive antiretroviral therapy (ART). Detailed analysis of these populations may reveal whether they are produced by central nervous system (CNS) reservoirs. METHODS: We performed a study of 101 asymptomatic participants on stable ART. HIV-1 RNA concentrations were cross-sectionally measured in CSF and plasma. In participants with CSF HIV-1 RNA concentrations sufficient for analysis, viral populations were genetically and phenotypically characterized over multiple time points. RESULTS: For 6% of participants (6 of 101), the concentration of HIV-1 RNA in their CSF was ≥0.5 log copies/mL above that of plasma (ie, CSF escape). We generated viral envelope sequences from CSF of 3 participants. One had a persistent CSF escape population that was macrophage-tropic, partially drug resistant, genetically diverse, and closely related to a minor macrophage-tropic lineage present in the blood prior to viral suppression and enriched for after ART. Two participants (1 suppressed and 1 not) had transient CSF escape populations that were R5 T cell-tropic with little genetic diversity. CONCLUSIONS: Extensive analysis of viral populations in 1 participant revealed that CSF escape was from a persistently replicating population, likely in macrophages/microglia, present in the CNS over 3 years of ART. CSF escape in 2 other participants was likely produced by trafficking and transient expansion of infected T cells in the CNS. Our results show that CNS reservoirs can persist during ART and that CSF escape is not exclusively produced by replicating CNS reservoirs.

Zones of influence for soil organic matter dynamics: A conceptual framework for data and models.

Soil organic matter (SOM) is an indicator of sustainable land management as stated in the global indicator framework of the United Nations Sustainable Development Goals (SDG Indicator 15.3.1). Improved forecasting of future changes in SOM is needed to support the development of more sustainable land management under a changing climate. Current models fail to reproduce historical trends in SOM both within and during transition between ecosystems. More realistic spatio-temporal SOM dynamics require inclusion of the recent paradigm shift from SOM recalcitrance as an 'intrinsic property' to SOM persistence as an 'ecosystem interaction'. We present a soil profile, or pedon-explicit, ecosystem-scale framework for data and models of SOM distribution and dynamics which can better represent land use transitions. Ecosystem-scale drivers are integrated with pedon-scale processes in two zones of influence. In the upper vegetation zone, SOM is affected primarily by plant inputs (above- and belowground), climate, microbial activity and physical aggregation and is prone to destabilization. In the lower mineral matrix zone, SOM inputs from the vegetation zone are controlled primarily by mineral phase and chemical interactions, resulting in more favourable conditions for SOM persistence. Vegetation zone boundary conditions vary spatially at landscape scales (vegetation cover) and temporally at decadal scales (climate). Mineral matrix zone boundary conditions vary spatially at landscape scales (geology, topography) but change only slowly. The thicknesses of the two zones and their transport connectivity are dynamic and affected by plant cover, land use practices, climate and feedbacks from current SOM stock in each layer. Using this framework, we identify several areas where greater knowledge is needed to advance the emerging paradigm of SOM dynamics-improved representation of plant-derived carbon inputs, contributions of soil biota to SOM storage and effect of dynamic soil structure on SOM storage-and how this can be combined with robust and efficient soil monitoring.

Dynamic Modeling and Target Loads of Sulfur and Nitrogen for Surface Waters in Finland, Norway, Sweden, and the United Kingdom.

The target load concept is an extension of the critical load concept of air pollution inputs to ecosystems. The advantage of target loads over critical loads is that one can define the deposition and the point in time (target year) when the critical (chemical) limit is no longer violated. This information on the timing of recovery requires dynamic modeling. Using a well-documented dynamic model, target loads for acidic deposition were determined for 848 surface waters across Finland, Norway, Sweden, and the United Kingdom for the target year 2050. In the majority of sites ( n = 675), the critical ANC-limit was predicted to be achieved by 2050; however, for 127 sites, target loads were determined. In addition, 46 sites were infeasible, i.e., even a reduction of anthropogenic deposition to zero would not achieve the limit by 2050. The average maximum target load for sulfur was 38% lower than the respective critical load across the study lakes ( n = 127). Target loads on a large regional scale can inform effects-based emission reduction policies; the current assessment suggests that reductions beyond the Gothenburg Protocol are required to ensure surface water recovery from acidification by 2050.

Deep instability of deforested tropical peatlands revealed by fluvial organic carbon fluxes.

Tropical peatlands contain one of the largest pools of terrestrial organic carbon, amounting to about 89,000 teragrams (1 Tg is a billion kilograms). Approximately 65 per cent of this carbon store is in Indonesia, where extensive anthropogenic degradation in the form of deforestation, drainage and fire are converting it into a globally significant source of atmospheric carbon dioxide. Here we quantify the annual export of fluvial organic carbon from both intact peat swamp forest and peat swamp forest subject to past anthropogenic disturbance. We find that the total fluvial organic carbon flux from disturbed peat swamp forest is about 50 per cent larger than that from intact peat swamp forest. By carbon-14 dating of dissolved organic carbon (which makes up over 91 per cent of total organic carbon), we find that leaching of dissolved organic carbon from intact peat swamp forest is derived mainly from recent primary production (plant growth). In contrast, dissolved organic carbon from disturbed peat swamp forest consists mostly of much older (centuries to millennia) carbon from deep within the peat column. When we include the fluvial carbon loss term, which is often ignored, in the peatland carbon budget, we find that it increases the estimate of total carbon lost from the disturbed peatlands in our study by 22 per cent. We further estimate that since 1990 peatland disturbance has resulted in a 32 per cent increase in fluvial organic carbon flux from southeast Asia--an increase that is more than half of the entire annual fluvial organic carbon flux from all European peatlands. Our findings emphasize the need to quantify fluvial carbon losses in order to improve estimates of the impact of deforestation and drainage on tropical peatland carbon balances.

Trajectories of change of youth depressive symptoms in routine care: shape, predictors, and service-use implications.

Depression is one of the main reasons for youth accessing mental health services, yet we know little about how symptoms change once youth are in routine care. This study used multilevel modeling to examine the average trajectory of change and the factors associated with change in depressive symptoms in a large sample of youth seen in routine mental health care services in England. Participants were 2336 youth aged 8-18 (mean age 14.52; 77% females; 88% white ethnic background) who tracked depressive symptoms over a period of up to 32 weeks while in contact with mental health services. Explanatory variables were age, gender, whether the case was closed, total length of contact with services, and baseline severity in depression scores. Faster rates of improvement were found in older adolescents, males, those with shorter time in contact with services, closed cases, and those with more severe symptoms at baseline. This study demonstrates that when youth self-report their depressive symptoms during psychotherapy, symptoms decrease in a linear trajectory. Attention should be paid to younger people, females, and those with lower than average baseline scores, as their symptoms decrease at a slower pace compared to others.

A good practice guide for translating and adapting hearing-related questionnaires for different languages and cultures.

OBJECTIVES: To raise awareness and propose a good practice guide for translating and adapting any hearing-related questionnaire to be used for comparisons across populations divided by language or culture, and to encourage investigators to publish detailed steps. DESIGN: From a synthesis of existing guidelines, we propose important considerations for getting started, followed by six early steps: (1) Preparation, (2, 3) Translation steps, (4) Committee Review, (5) Field testing and (6) Reviewing and finalising the translation. STUDY SAMPLE: Not applicable. RESULTS: Across these six steps, 22 different items are specified for creating a questionnaire that promotes equivalence to the original by accounting for any cultural differences. Published examples illustrate how these steps have been implemented and reported, with shared experiences from the authors, members of the International Collegium of Rehabilitative Audiology and TINnitus research NETwork. CONCLUSIONS: A checklist of the preferred reporting items is included to help researchers and clinicians make informed choices about conducting or omitting any items. We also recommend using the checklist to document these decisions in any resulting report or publication. Following this step-by-step guide would promote quality assurance in multinational trials and outcome evaluations but, to confirm functional equivalence, large-scale evaluation of psychometric properties should follow.

Adaptation and psychometric properties of the spanish version of the yp-core (Young Person's Clinical Outcomes in Routine Evaluation).

INTRODUCTION: Given the increasing prevalence of mental health problems in the general population, it is indispensable to use assessment tools aimed to assess the outcome of therapeutic interventions in order to refine the process of psychological rehabilitation. METHOD: We describe the process of adaptation into Spanish and a first psychometric study of the Young Person's- Clinical Outcomes in Routine Evaluation (YP-CORE), an instrument designed to measure the outcome in terms of general distress of therapeutic interventions in young people (11-16 years). 104 adolescents participated in the clinical and 131 in the non-clinical samples. RESULTS: Analyses showed good levels of acceptability, adequate internal consistency and acceptable test-retest stability, with moderately high correlations between administrations. In addition, the instrument yielded significant correlations with all dimensions of the Youth Self Report, the highest being between both total scores. Crucially, discriminated between clinical and non-clinical samples and showed a small effect of age but a larger effect of gender, with higher scores for females. The Principal Component Analysis replicates the original structure. Cut-off scores to calculate the reliable and clinically significant change are provided. CONCLUSIONS: These results support initial use of the instrument though there are certain limitations that indicate the need for more research with larger and more representative samples, in which the psychometric properties of the instrument should be verified.

The Finnish Clinical Outcome in Routine Evaluation Outcome Measure: psychometric exploration in clinical and non-clinical samples.

The Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM) is a 34-item self-report measure designed to monitor changes in psychiatric patients. It has been translated into 25 languages, including Finnish. This is the first psychometric exploration of Finnish CORE-OM data. The aim of the study is to examine acceptability, internal consistency and convergent validity of the Finnish CORE-OM scores. Translation of the CORE-OM from English to Finnish was undertaken according to recommended protocols. Psychometric exploration was conducted in two samples: psychiatric patients (N = 201) and non-clinical participants (N = 209). Participation was voluntary and involved completion of all scales. Convergent validity was tested in terms of the mean score differences between clinical and non-clinical samples and correlations against the Beck Depression Inventory (BDI) and the Symptom Checklist (SCL-90). Among the clinical sample, all domains showed good or acceptable internal reliability. In the non-clinical sample, the alphas of domains were good or acceptable, with only the alphas of the Risk domain registering as low. There were no marked gender or age effects. CORE-OM scores correlated strongly with both the BDI and SCL-90, particularly in patients' data. Some possible effects of Finnish language were found. The Finnish translation of the CORE-OM is psychometrically sound and can be recommended for use in Finnish mental health and clinical settings. However, further investigation in larger and different samples will clarify the generalizability its psychometric properties. Clinical services are encouraged to contribute to the creation of a collaborative Finnish CORE practice research network.

Psychometric properties of the Finnish version of the Young Person's Clinical Outcomes in Routine Evaluation (YP-CORE) questionnaire.

BACKGROUND: An increasing need exists for suitable measures to evaluate treatment outcome in adolescents. YP-CORE is a pan-theoretical brief questionnaire developed for this purpose, but it lacks studies in different cultures or languages. AIMS: To explore the acceptability, factor structure, reliability, validity, and sensitivity to change of the Finnish translation of YP-CORE. METHODS: The study was conducted at the Department of Adolescent Psychiatry, Helsinki University Central Hospital. A Finnish translation was prepared by a team of professionals and adolescents. A clinical sample of 104 patients was asked to complete the form together with BDI-21 and BAI, and 92 of them filled the forms again after a 3-month treatment. Analysis included acceptability, confirmatory factor analysis, internal and test-re-test reliability, concurrent validity, influence of gender and age, and criteria for reliable change. RESULTS: YP-CORE was well accepted, and the rate of missing values was low. Internal consistency (α = 0.83-.92) and test-re-test reliability were good (r = 0.69), and the results of CFA supported a one-factor model. YP-CORE showed good concurrent validity against two widely used symptom-specific measures (r = 0.62-0.87). Gender had a moderately strong effect on the scores (d = 0.67), but the effect of age was not as evident. The measure was sensitive to change, showing a larger effect size (d = 0.55) than in the BDI-21 and BAI (d = 0.31-0.50). CONCLUSIONS: The results show that the translation of YP-CORE into Finnish has been successful, the YP-CORE has good psychometric properties, and the measure could be taken into wider use in clinical settings for outcome measurement in adolescents.
