A rapid and reliable method is described in which quantitative differential thermal analysis is used to anatyse for silver carbonate in the presence of silver(II) oxide. The method is applicable quantitatively above 2070 silver carbonate and semiquantitatively above 5 700.
Background: Pediatric chronic pain is a prevalent condition that requires significant coping to encourage optimal functioning; however, relevant research is vast, heterogeneous, and difficult to interpret. To date, no attempt has been made to map and summarize the measurement and conceptualization of coping responses in the context of pediatric chronic pain.Objectives: A scoping review was conducted to map and summarize the participant characteristics, methodologies, theoretical frameworks, and measures used to assess coping responses in youth with chronic pain. The extent to which authors used definitions and examples of coping responses (conceptual clarity) as well as consistently used measures (measurement consistency) and their corresponding conceptualizations (conceptual consistency) relative to how they were intended to be used were assessed.Methods: Searches were conducted through MEDLINE (PubMed) and PsycINFO. Following title/abstract screening, full-text extractions were performed on 125 English-language publications on coping in youth with chronic pain.Results: Of the 125 studies, only 12.8% used a theoretical framework to explain the coping responses assessed, and even fewer (7.2%) used theory to guide measure selection. Conceptual clarity was rated “low/very low” (i.e., no definitions and/or examples) for 47.2% of studies. The majority of studies were conducted in the United States (67%) and a preponderance of White and female participants was sampled. The research primarily used quantitative methods (85%) and cross-sectional designs (67%). Parent- or self-report questionnaires were the most common methods for assessing coping (86%). Of the 95 studies that utilized one of the 14 questionnaires with known psychometric properties, 33.7 and 55.8% had one or more discrepancies for conceptual and measurement consistency, respectively.Conclusions: This review highlights the lack of clear descriptions and theoretical frameworks of coping responses for pediatric chronic pain. Inconsistencies in the measurement and conceptualization of coping responses limit research and clinical advancements. As a field, we need to strive toward using well-developed theory to create fewer, more well-established standardized measures with clearly defined coping responses. Opportunities for qualitative and observational research in more diverse patient populations should be considered for theory construction and measure validation.Clinical Trial Registration:https://osf.io/xvn2a/?view_only=eff04e0c0b9649be89d403b10e9ff082.
This pilot examines a self-distancing augmentation to exposure. Nine youth with anxiety (ages 11–17; 67% female) completed treatment. The study employed a brief (eight session) crossover ABA/BAB design. Exposure difficulty, engagement with exposure, and treatment acceptability were examined as primary outcome variables. Visual inspection of plots indicated that youth completed more difficult exposures during augmented exposure sessions [EXSD] than classic exposure sessions [EX] by therapist- and youth-report and that therapists reported higher youth engagement during EXSD than EX sessions. There were no significant differences between EXSD and EX on exposure difficulty or engagement by therapist- or youth-report. Treatment acceptability was high, although some youth reported that self-distancing was “awkward”. Self-distancing may be associated with increased exposure engagement and willingness to complete more difficult exposures, which has been linked to treatment outcomes. Future research is needed to further demonstrate this link, and link self-distancing to outcomes directly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
