The Behavioural Outcomes of Anxiety scale (BOA): A preliminary validation in stroke survivors

© 2014 The British Psychological Society. Objectives To determine the psychometric properties of an observational scale of anxiety.Design A cross-sectional and longitudinal survey with stroke survivor-carer dyads.Methods Eighty-nine dyads recruited in community stroke groups completed: a demographic questionnaire; the Behavioural Outcomes of Anxiety scale (BOA), survivor-rated (survivor BOA) and carer-rated (carer BOA) versions; the anxiety scale of the Hospital Anxiety and Depression Scales (HADS-A), also in carer and survivor versions. Twenty-seven survivors and carers repeated the BOA after 1 week.Results Correlations between the carer BOA and the survivor HADS-A (r =.55, p <.001) and the survivor BOA (r =.73, p <.001) demonstrated construct validity. Cronbach's alpha for the carer BOA was.81; item statistics did not identify any items for exclusion. The test-retest coefficient at 1 week was 0.83. Receiver operating characteristic analysis against the survivor HADS-A and BOA produced areas under the curve of 0.75 and 0.88, respectively. At a cut-off score of 13/14 sensitivity and specificity against the HADS-A were 0.77 and 0.58, respectively, and 0.86 and 0.68 against the survivor BOA. The impact of stroke on memory was associated with elevated anxiety. Scores for both BOA versions were independent of demographic variables.Conclusions The carer BOA has acceptable psychometric properties and is independent of survivor demographic variables such as age. It identifies self-reported cases with acceptable sensitivity and specificity. It has potential for use with persons unable to self-report anxiety. Further validation is recommended, but its continuing use is supported. © 2014 The British Psychological Society

Mixed Methods Evaluation of State Targeted Response to the Opioid Crisis in Ohio

Background: In 2017, the Substance Abuse and Mental Health Services Administration awarded State Targeted Response (STR) grants through the 21st Century Cures Act to help states address the opioid crisis. While there are publications that discuss how each state allocated their STR grant awards, there is a paucity of evaluations illustrating the impact of STR grant activities on clients of opioid use disorder (OUD) treatment, family members of persons living with OUD, community professionals whose work involves addressing OUD, as well as impacts on local communities. This longitudinal qualitative study assessed the impact of STR grant-funded projects on communities in Ohio particularly hard hit by the opioid epidemic. Methods: Data were collected through a mixed research methodology from November 2017 through April 2019. Epidemiologists conducted focus groups and administered surveys in 4 geographically different areas of the state. Study objectives included assessments of community messaging related to opioids, level of perceived stigma for OUD, knowledge of available services and processes for accessing them, and perception of community treatment service needs. Results: A total of 940 respondents participated in 3 cycles (6 months each) of focus groups. Key findings included increased naloxone knowledge and experience, increased proportion of persons living with OUD receiving medication-assisted treatment (MAT), and a 2.5 time increase in the number of reported positive observations of community change. While the level of perceived stigma for OUD remained consistent (moderate) throughout the study, respondents throughout cycles observed an increasing number of community approaches, such as public awareness campaigns and recovery rallies, to impart knowledge, change attitudes, and reduce stigma. Conclusion: Evaluations of STR funded activities and programs could help illustrate the value that additional funding might have over time in reducing stigma related to OUD and increasing knowledge of available treatment services in communities

Infant and Toddler Programs: Recommendations for a Stimulating Learning Environment

Recommendations for practices that strengthen early childhood programs are proposed based on findings from two studies. The Infant-Toddler Environment Rating Scale-Revised is widely used to assess infant a toddler classrooms. A total of 102 infant and toddler classrooms in Missouri were observed for these studies and provide the basis for information in this recommended practices document. Items from the Environment Rating Scale that were consistently rated as below average were divided into three program components: room/furniture design, displayed materials, and play materials. Specific recommendations for improving programs are outlined

Infant and Toddler Programs: Recommendations for Quality Child-Teacher Interactions

Recommendations for practices that strengthen early childhood programs are proposed based on findings from two studies. In one study, researchers in the Midwest Child Care Research Consortium conducted a study to assess program quality. In the second study, observations were conducted using the Environment Rating Scales as part of the Missouri Quality Rating System Pilot Study. The Infant-Toddler Environment Rating Scale-Revised is widely used to assess infant and toddler classrooms. Items from the Environment Rating Scale that were consistently rated as below average are divided into four program components: displayed materials, block play, pretend play, and free play. Specific recommendations for improving programs are outlined

Home-Based Programs: Recommendations to Improve Program Quality

Recommendations for practices that strengthen early childhood programs are proposed based on findings from two studies. The Family Day Care Rating Scale is widely used to assess program quality. A total of 223 home-based programs in Missouri were observed for these studies and provide the basis for information in this recommended practices document. Items from the Environment Rating Scale that were consistently rated as below average were divided into two program components: health and safety issues and programming. Specific recommendations for improving programs are outlined

Preschool Classrooms: Recommendations to Improve the Quality of Early Childhood Programs

Recommendations for practices that strengthen early childhood programs are proposed based on findings from two studies. The Early Childhood Environment Rating Scale-Revised is widely used to assess preschool classrooms. A total of 191 preschool classrooms in Missouri were observed for these studies and provide the basis for information in this recommended practices document. Items from the Environment Rating Scale that were consistently rated as below average were divided into two program components: health and safety issues and programming/curriculum.

Evaluating efficacy of a ballast water filtration system for reducing spread of aquatic species in freshwater ecosystems

Biological invasions by non-indigenous species are considered a leading threat to biodiversity, with prevention being a key management strategy. Consequently, numerous commercial ballast water treatment systems have been, or are being, developed to prevent future aquatic invasions. However, most treatment systems are being designed for the many vessels undertaking long transoceanic voyages in marine waters rather than the relatively few vessels operating on short voyages in freshwater, such as those in the Laurentian Great Lakes. Here we conduct testing of the biological efficacy of a 40 µm ballast water filtration unit through shipboard trials. We test the hypotheses that i) filtration will significantly reduce abundance of zooplankton greater than 50 µm in size but not phytoplankton 10 to 50 µm in size; ii) filtration will reduce zooplankton abundances in ballast water below International Maritime Organization discharge standards, but not those of phytoplankton; and iii) filtration will alter the community composition of zooplankton, non-randomly reducing invasion risk of larger taxa. During the summer of 2012, three shipboard trials were conducted. Ballast water samples were collected using a before-after experimental design. Our study showed that filtration significantly reduced abundance of copepods and cladocerans, but not of juvenile dreissenid veligers and rotifers. Contrary to our expectation, phytoplankton densities were also significantly lower after the treatment. Overall, ballast water treated during our tests would not meet proposed international discharge standards. Filtration altered relative abundance of zooplankton, but did not reduce introduction risk of any taxonomic group due to the small juvenile stages and dormant eggs which passed through the treatment. While we do not rule out filtration as a ballast water treatment option for zooplankton in the future, our tests indicate further development is required for meaningful reduction of invasion risk

Ancient Chinese methods are remarkably effective for the preparation of artemisinin-rich extracts of Qing Hao with potent antimalarial activity.

yesAncient Chinese herbal texts as far back as the 4th Century Zhou hou bei ji fang describe methods for the use of Qing Hao (Artemisia annua) for the treatment of intermittent fevers. Today, the A. annua constituent artemisinin is an important antimalarial drug and the herb itself is being grown and used locally for malaria treatment although this practice is controversial. Here we show that the ancient Chinese methods that involved either soaking, (followed by wringing) or pounding, (followed by squeezing) the fresh herb are more effective in producing artemisinin-rich extracts than the usual current method of preparing herbal teas from the dried herb. The concentrations of artemisinin in the extracts was up to 20-fold higher than that in a herbal tea prepared from the dried herb, but the amount of total artemisinin extracted by the Chinese methods was much less than that removed in the herbal tea. While both extracts exhibited potent in vitro activities against Plasmodium falciparum, only the pounded juice contained sufficient artemisinin to suppress parasitaemia in P. berghei infected mice. The implications of these results are discussed in the context of malaria treatment using A. annua infusions

A self-determination perspective of strengths use at work: Examining its determinant and performance implications

We investigate the role of strengths use in the workplace by drawing on self-determination theory (SDT) to propose that strengths use at work can yield performance benefits in terms of task performance and discretionary helping, and that the social context, in the form of leader autonomy support, can promote employees’ strengths use. Further, consistent with an interactional psychology perspective, we contend that the relationship between autonomy support and strengths use will be stronger among individuals with strong independent self-construal. We tested the model using matched data from 194 employees and their supervisors and found evidence for the relevance of strengths use at work, even after accounting for the role of intrinsic motivation. In addition to providing practical implications on developing employee strengths use and how to do so, this study advances theory and research on workplace strength use, SDT, and positive organizational behavior
