Geochemistry and paleoceanographic setting of Central Nevada bedded barites

Journal ArticleThe bedded barite deposits of central Nevada are hosted by rocks of the Roberts Mountains allochthon and constitute the largest barite reserves in North America. Detailed geochemical studies of three barite deposits in the Devonian Slaven Chert indicate that rocks surrounding the barite have elevated concentrations of carbon and phosphorousr elative to nonbarite-bearing rocks. Rare earth element data suggest that the barites were deposited in oxygenated seawater far from a spreading center. Ratios of Al, Ti, Fe, and Mn indicate that hydrothermal input to the sediment was minor relative to detrital input. The assembled data suggest a biogenic rather than a hydrothermal origin for the barite deposits. A model is proposed in which the barites were deposited at the O2-H2S transition of a coastal upwelling system in the Late Devonian ocean. This model is consistent with recent paleoceanographica nalyses of rocks in the Roberts Mountains allochthon, and studies indicating that the Late Devonian marked the transition from an anoxic to an oxic deep ocean

The Cognitive Behaviour Therapy Scale for Children and Young People (CBTS-CYP): development and psychometric properties

Background: There is increased interest in developing training in cognitive behaviour therapy (CBT) with children and young people. However, the assessment of clinical competence has relied upon the use of measures such as the Cognitive Therapy Scale-Revised (CTSR: Blackburn et al., 2001) which has been validated to assess competence with adults. The appropriateness of this measure to assess competence when working with children and young people has been questioned. Aim: This paper describes the development and initial evaluation of the Cognitive Behaviour Therapy Scale for Children and Young People (CBTSCYP) developed specifically to assess competence in CBT with children and young people. Method: A cross section of child CBT practitioners (n = 61) were consulted to establish face validity. Internal reliability, convergent validity and discriminative ability were assessed in two studies. In the first, 12 assessors independently rated a single video using both the Cognitive Behaviour Therapy Scale for Children and Young People (CBTS-CYP) and Cognitive Therapy Scale-Revised (CTS-Revised: Blackburn et al., 2001). In the second, 48 different recordings of CBT undertaken with children and young people were rated on both the CBTS-CYP and CTS-R. Results: Face validity and internal reliability of the CBTS-CYP were high, and convergent validity with the CTS-R was good. The CBTS-CYP compared well with the CTSR in discriminative ability. Conclusion: The CBTS-CYP provides an appropriate way of assessing competence in using CBT with children and young people. Further work is required to assess robustness with younger children and the impact of group training in reducing interrater variations

Making sense of child and adolescent mental health services (CAMHS):An audit of the referral journey and the use of routine outcome measures (ROMS)

Background: There is increased emphasis on the national reporting of Routine Outcome Measures (ROMS) as a way of improving Child and Adolescent Mental Health Services (CAMHS). This data needs to be viewed in context so that reasons for outcome completion rates are understood and monitored over time. Method: We undertook an in-depth prospective audit of consecutive referrals accepted into the Bath and North East Somerset, Swindon and Wiltshire (BSW) CAMHS service from November 2017 to January 2018 (n = 1074) and April to September 2019 (n = 1172). Results: Across both audits 90% of those offered an appointment were seen with three quarters completing baseline ROMS. One in three were not seen again with around 30% still being open to the service at the end of each audit. Of those closed to the service, paired ROMS were obtained for 46% to 60% of cases. There were few changes in referral problems or complexity factors over time. Conclusion: Understanding the referral journey and the reasons for attrition will help to put nationally collected data in context and can inform and monitor service transformation over time.</p

Acceptability, Use, and Safety of a Mobile Phone App (BlueIce) for Young People Who Self-Harm: Qualitative Study of Service Users’ Experience

Background: Self-harm is common among adolescents and is associated with a number of negative psychosocial outcomes including a higher risk of suicide. Recent reviews highlight the lack of research into specific interventions for children and young people who self-harm. Developing innovative interventions that are coproduced with individuals with lived experience and that reduce self-harm are key challenges for self-harm prevention. Objective: The aim of this study was to explore the acceptability, use, and safety of BlueIce, a mobile phone app for young people who self-harm and who are attending child and adolescent mental health services (CAMHS). Methods: This study is part of a mixed methods phase 1 trial of BlueIce. Young people aged 12-17 years attending specialist CAMHS were recruited. Clinicians were invited to refer young people who were self-harming or who had a history of self-harm. On consent being obtained and baseline measures taken, participants used BlueIce as an adjunct to usual care for an initial familiarization period of 2 weeks. If after this time they wanted to continue, they used BlueIce for a further 10 weeks. Semistructured interviews were conducted at postfamiliarization (2 weeks after using BlueIce) and postuse (12 weeks after using BlueIce) to assess the acceptability, use, and safety of BlueIce. We undertook a qualitative analysis using a deductive approach, and then an inductive approach, to investigate common themes. Results: Postfamiliarization interviews were conducted with 40 participants. Of these, 37 participants elected to use BlueIce, with postuse interviews being conducted with 33 participants. Following 6 key themes emerged from the data: (1) appraisal of BlueIce, (2) usability of BlueIce, (3) safety, (4) benefits of BlueIce, (5) agency and control, and (6) BlueIce less helpful. The participants reported that BlueIce was accessible, easy to use, and convenient. Many highlighted the mood diary and mood lifter sections as particularly helpful in offering a way to track their moods and offering new strategies to manage their thoughts to self-harm. No adverse effects were reported. For those who did not find BlueIce helpful, issues around motivation to stop self-harming impeded their ability to use the app. Conclusions: BlueIce was judged to be a helpful and safe way of supporting adolescents to manage thoughts of self-harming. Adolescents reported numerous benefits of using BlueIce, and all would recommend the app to other young people who were struggling with self-harm. These preliminary findings are encouraging and provide initial support for the acceptability of BlueIce as a self-help intervention used in conjunction with the traditional face-to-face therapy

Psychometric properties of the Cognitive Behaviour Therapy Scale for Children and Young People (CBTS-CYP) in a Turkish sample

BACKGROUND: Cognitive behavioural therapy (CBT) training is highly demanded by clinicians; however, a standardized competence assessment for professionals working with children and young people (CYP) can be problematic. Psychometric tools used for this purpose are typically adult oriented measures. AIM: The present study provides psychometric properties of the Cognitive Behaviour Therapy Scale for Children and Young People (CBTS-CYP) derived from a comparative analysis with the Cognitive Therapy Scale (CTS). METHOD: The CBTS-CYP was used alongside CTS in a CBT supervision training course, consisting of a cohort of 51 therapists. A total of 36 audio/video recorded full CBT sessions were assessed for the purpose of determining CBT competence and adherence to the theory and model. The training involved a total of 80 hours of supervision in 10 meetings via an online videoconferencing platform between July 2020 and February 2021. RESULTS: Face validity and inter-rater reliability of CBTS-CYP were high, with the intraclass correlation values being good (0.60-0.74) or excellent (0.74 and above); the correlations of each CBTS-CYP and CTS items were significant; internal consistency of the scale showed that Cronbach alpha values for total-scale and its two subdimensions were above .93. For a cut-off score of 55 out of 90, sensitivity reached 90.73% and specificity 90.73%. A score of 2 points or above from any single item could be considered as the second minimum criterion for competence. CONCLUSIONS: CBTS-CYP offers a valid and reliable scale to evaluate the competence and adherence quality of CBT sessions with children and adolescents.</p
