Cognitive Behavioural Therapy for schizophrenia - outcomes for functioning, distress and quality of life : A meta-analysis

Background: The effect of cognitive behavioural therapy for psychosis (CBTp) on the core symptoms of schizophrenia has proven contentious, with current meta-analyses finding at most only small effects. However, it has been suggested that the effects of CBTp in areas other than psychotic symptoms are at least as important and potentially benefit from the intervention. Method: We meta-analysed RCTs investigating the effectiveness of CBTp for functioning, distress and quality of life in individuals diagnosed with schizophrenia and related disorders. Data from 36 randomised controlled trials (RCTs) met our inclusion criteria- 27 assessing functioning (1579 participants); 8 for distress (465 participants); and 10 for quality of life (592 participants). Results: The pooled effect size for functioning was small but significant for the end-of-trial (0.25: 95% CI: 0.14 to 0.33); however, this became non-significant at follow-up (0.10 [95%CI -0.07 to 0.26]). Although a small benefit of CBT was evident for reducing distress (0.37: 95%CI 0.05 to 0.69), this became nonsignificant when adjusted for possible publication bias (0.18: 95%CI -0.12 to 0.48). Finally, CBTp showed no benefit for improving quality of life (0.04: 95% CI: -0.12 to 0.19). Conclusions: CBTp has a small therapeutic effect on functioning at end-of-trial, although this benefit is not evident at follow-up. Although CBTp produced a small benefit on distress, this was subject to possible publication bias and became nonsignificant when adjusted. We found no evidence that CBTp increases quality of life post-intervention.Peer reviewedFinal Published versio

Near-Infrared Constraints on the Presence of Warm Dust at Metal-Rich, Helium Atmosphere White Dwarfs

Here, we present near-infrared spectroscopic observations of 15 helium atmosphere, metal-rich white dwarfs obtained at the NASA Infrared Telescope Facility. While a connection has been demonstrated between the most highly polluted, hydrogen atmosphere white dwarfs and the presence of warm circumstellar dust and gas, their frequency at the helium atmosphere variety is poorly constrained. None of our targets show excess near-infrared radiation consistent with warm orbiting material. Adding these near-infrared constraints to previous near- and mid-infrared observations, the frequency of warm circumstellar material at metal-bearing white dwarfs is at least 20% for hydrogen-dominated photospheres, but could be less than 5% for those effectively composed of helium alone. The lower occurrence of dust disks around helium atmosphere white dwarfs is consistent with Myr timescales for photospheric metals in massive convection zones. Analyzing the mass distribution of 10 white dwarfs with warm circumstellar material, we search for similar trends between the frequency of disks and the predicted frequency of massive planets around intermediate mass stars, but find the probability that disk-bearing white dwarfs are more massive than average is not significant.Comment: AJ, in pres

Parent-mediated communication interventions for improving the communication skills of preschool children with non-progressive motor disorders

Background: Children with motor disorders can have difficulties in producing accurate and consistent movements for speech, gesture or facial expression (or a combination of these), making their communication difficult to understand. Parents may be offered training to help recognise and interpret their child's signals and to stimulate their children's development of new communication skills. Objectives: To assess the effectiveness of parent-mediated communication interventions, compared to no intervention, treatment as usual or clinician-mediated interventions, for improving the communication skills of preschool children up to five years of age who have non-progressive motor disorders. Search methods: We searched CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, 12 other databases and three trials registers in July 2017. We also searched the reference lists of relevant papers and reviews, and contacted experts working in the field to find unpublished studies. Selection criteria: We included studies that used randomised or quasi-randomised designs; compared a parent-mediated communication intervention with no treatment, treatment as usual or clinician-mediated therapy; and included children with non-progressive motor disorders up to five years of age. Data collection and analysis: We used the standard methodological procedures expected by Cochrane. Main results: This review included two randomised controlled trials involving 38 children (20 boys, 18 girls), aged 15 to 96 months, and their mothers. All children had developmental disabilities; 10 had motor disorders, but it was unclear if these motor disorders affected their gestural, vocal or verbal communication. Mothers attended eight group training sessions over 11 to 12 weeks and received two or three home visits. Outcomes were assessed immediately after training. We found no report of longer-term follow-up. One study took place at an intervention centre in Canada and the other in South Korea. Both studies recruited small numbers of participants from single centres. Since it is not possible to blind participants attending or therapists providing training to group allocation, we considered both studies to be at high risk of performance bias. We also rated one study at high risk of attrition bias, and both studies at low risk of reporting bias. There was very low-quality evidence for all outcomes assessed. There was no evidence of an effect of training for children's initiation of conversation or engagement in joint attention during interaction with their mothers. Mothers who received training became more responsive to their children's communication, but there were no differences in the extent to which they controlled conversation by directing their children. Missing data meant that we were unable to evaluate the effects of training on children's frequency of communication, frequency of spoken language in conversation, speech production, or receptive or expressive language development. There were no effects on maternal stress. We found no reports of the effects of parent training on children's use of individual communication skills, such as asking questions or providing information, on their generic participation or adverse outcomes. Neither did we find reports of mothers' satisfaction with treatment, its acceptability or their compliance with it. Authors' conclusions: There is only limited, very low quality evidence that parent-mediated communication interventions may be associated with improvements in interaction between mothers and their preschool children who have motor disorders. The indirectness of the study samples and high risk of bias in the included the studies significantly limits our confidence in the evidence, as do issues with study design and lack of detail in results. It is not clear if training has been tested with children whose motor disorders limit the consistency and accuracy of movements underpinning spoken or gestural communication. Some speech and language therapists currently provide communication training for parents. Further research, with larger numbers of children whose movement disorders affect their speech and gestures, coupled with detailed reporting of children's baseline skills, is needed to test whether communication training for parents can help them to promote the communication development of their young children with movement disorders

Obesity prevention in early life: An opportunity to better support the role of Maternal and Child Health Nurses in Australia

© 2015 Laws et al.; licensee BioMed Central. Background: Because parents with young children access primary health care services frequently, a key opportunity arises for Maternal and Child Health (MCH) nurses to actively work with families to support healthy infant feeding practices and lifestyle behaviours. However, little is known regarding the extent to which MCH nurses promote obesity prevention practices and how such practices could be better supported. Methods: This mixed methods study involved a survey of 56 MCH nurses (response rate 84.8%), 16 of whom participated in semi-structured qualitative interviews. Both components aimed to examine the extent to which nurses addressed healthy infant feeding practices, healthy eating, active play and limiting sedentary behavior during routine consultations with young children 0-5 years. Key factors influencing such practices and how they could be best supported were also investigated. All data were collected from September to December 2013. Survey data were analysed descriptively and triangulated with qualitative interview findings, the analysis of which was guided by grounded theory principles. Results: Although nurses reported measuring height/length and weight in most consultations, almost one quarter (22.2 %) reported never/rarely using growth charts to identify infants or children at risk of overweight or obesity. This reflected a reluctance to raise the issue of weight with parents and a lack of confidence in how to address it. The majority of nurses reported providing advice on aspects of infant feeding relevant to obesity prevention at most consultations, with around a third (37 %) routinely provided advice on formula preparation. Less than half of nurses routinely promoted active play and only 30 % discussed limiting sedentary behaviour such as TV viewing. Concerns about parental receptiveness and maintaining rapport were key barriers to more effective implementation. Conclusion: While MCH nurses are well placed to address obesity prevention in early life, there is currently a missed public health opportunity. Improving nurse skills in behaviour change counseling will be key to increasing their confidence in raising sensitive lifestyle issues with parents to better integrate obesity prevention practices into normal MCH service delivery

A mixed methods study to explore the effects of program design elements and participant characteristics on parents' engagement with an mHealth program to promote healthy infant feeding: The growing healthy program

Copyright © 2019 Taki, Russell, Lymer, Laws, Campbell, Appleton, Ong and Denney-Wilson. Purpose: Mobile health (mHealth) interventions have great potential to promote health. To increase consumer engagement in mHealth interventions it is necessary to address factors that influence the target demographic. The Growing healthy (GH) program is the first obesity prevention program delivered via a smartphone app and website offering evidence-based information on infant feeding from birth until 9 months of age. This sub-study aimed to explore how the design features, quality of the app and participant characteristics influenced parents' engagement with the GH app. Methods: A sequential mixed methods design was used. The GH app participants (225/301) were considered for this sub-study. Participant app engagement was measured through a purpose-built Engagement Index (EI) using app metrics. Participants were categorized as low, moderately or highly engaged based on their EI score upon completing the 9 months program and were then invited to participate in semi-structured telephone interviews. Participants who used the app program, given an EI score and expressed interest to participate in these interviews were eligible. The interviews explored factors that influenced app engagement including delivery features and quality. Thematic analysis networks was used for analysis. Results: 108/225 expressed interest and 18 interviews were conducted from low (n = 3), moderately (n = 7), or highly (n = 8) engaged participants based on purposeful sampling. Participants defined as highly engaged were likely to be a first-time parent, felt the app content to be trustworthy and the app design facilitated easy navigation and regularly opened the push notifications. Participants defined as having low or moderate engagement were likely to have experience from previous children, felt they had sufficient knowledge on infant feeding and the app did not provide further information, or experienced technological issues including app dysfunction due to system upgrades. Conclusions/Implications: This study demonstrated a novel approach to comprehensively analyse engagement in an mHealth intervention through quantitative (Engagement Index) and qualitative (interviews) methods. It provides an insight on maximizing data collected from these programs for measuring effectiveness and to understand users of various engagement levels interaction with program features. Measuring this can determine efficacy and refine programs to meet user requirements

The impact of a team-based intervention on the lifestyle risk factor management practices of community nurses: outcomes of the community nursing SNAP trial

BackgroundLifestyle risk factors like smoking, nutrition, alcohol consumption, and physical inactivity (SNAP) are the main behavioural risk factors for chronic disease. Primary health care is an appropriate setting to address these risk factors in individuals. Generalist community health nurses (GCHNs) are uniquely placed to provide lifestyle interventions as they see clients in their homes over a period of time. The aim of the paper is to examine the impact of a service-level intervention on the risk factor management practices of GCHNs.MethodsThe trial used a quasi-experimental design involving four generalist community nursing services in NSW, Australia. The services were randomly allocated to either an intervention group or control group. Nurses in the intervention group were provided with training and support in the provision of brief lifestyle assessments and interventions. The control group provided usual care. A sample of 129 GCHNs completed surveys at baseline, 6 and 12 months to examine changes in their practices and levels of confidence related to the management of SNAP risk factors. Six semi-structured interviews and four focus groups were conducted among the intervention group to explore the feasibility of incorporating the intervention into everyday practice.ResultsNurses in the intervention group became more confident in assessment and intervention over the three time points compared to their control group peers. Nurses in the intervention group reported assessing physical activity, weight and nutrition more frequently, as well as providing more brief interventions for physical activity, weight management and smoking cessation. There was little change in referral rates except for an improvement in weight management related referrals. Nurses’ perception of the importance of ‘client and system-related’ barriers to risk factor management diminished over time.ConclusionsThis study shows that the intervention was associated with positive changes in self-reported lifestyle risk factor management practices of GCHNs. Barriers to referral remained. The service model needs to be adapted to sustain these changes and enhance referral

How well do police specialists risk assess Registered Sexual Offenders?

This study examined 91 Active Risk Management System (ARMS) assessments from four police areas across England and Wales. ARMS is a tool that guides criminal justice practitioners to assess and develop formal risk management plans based on the risks and strengths of individual clients convicted of sexual offending. This present study is particularly concerned with the application of this new tool and the quality of subsequent risk assessment as a result of police practitioner assessment. Findings indicate the quality of ARMS assessments were not to the expected standard. The study found while there were acceptable levels of detail and evidence documented by practitioners across individual areas; overall, assessor risk ratings and risk management plans were poor. This paper provides an outline of these findings, making suggestions for areas of improvement, along with recommendations for policy, practice, and research

High phytoplankton growth and production rates in oligotrophic Hawaiian coastal waters

Plankton biomass, material fluxes, e.g. 14C uptake, and specific growth rates are related quantities. In the course of comparing various methods of measuring these properties in September 1982 off Oahu, Hawaii, we found specific growth rates of 1–2·d−1. Such rates approach the maximum expected values observed in laboratory cultures
