The value of mixed-method research with families of children with autism spectrum disorder: a grounded theory protocol

This study emphasizes the value of mixed-method research methodologies in research with families of children with Neurodevelopmental Disorders (NDD), specifically Autism Spectrum Disorder (ASD). The category of NDD in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) includes Intellectual Developmental Disorders, Communication Disorders, Autism Spectrum Disorder (ASD), Attention-Deficit/Hyperactivity Disorder (ADHD), Specific Learning Disorder, and Motor Disorders. NDD affect not only the child, but the family as well. Limited research has utilized a qualitative or a mixed-methods approach to explore the experiences, stressors, and resilience of parents of children with ASD in non-Western contexts. Providing an example of a mixed-methods design, this paper illustrates a multiple-phase doctoral study on Autism Spectrum Disorder (ASD). The study’s objective is to conduct an embedded design, mixed-method analysis using grounded theory to better understand parents’ (mothers and fathers) experiences, stressors, well-being and resilience in the Malaysian cultural context. Integrating and blending the approaches together allows for deeper analysis and theory development, while allowing rich cultural data to be shared in research areas where limited information is present. Revealing the family system, cultural, and contextual processes, the findings have important implications for professionals and researchers to develop more meaningful, culturally-tailored, and evidenced-based interventions

Wellbeing of mothers of children with “A-U-T-I-S-M” in Malaysia: an interpretative phenomenological analysis study

Background: This qualitative study aimed to explore how mothers gave meaning to their experiences of raising a child with autism spectrum disorder (ASD) in Malaysia. Methods: Using interpretative phenomenological analysis, semistructured interviews were conducted with 8 Malaysian mothers from different ethnic backgrounds (4 Chinese, 3 Malays, and 1 Indian). Results: Three themes for the mothers’ adaptation and wellbeing development were identified, including Problem realisation within the context: Learning to spell A-U-T-I-S-M in Malaysia, WE are living with autism, and Resilient overcoming: Climbing Mount Kinabalu. The mothers viewed their child’s ASD symptoms and behaviour problems (e.g., hyperactivity and sleep difficulties) as taking a toll on wellbeing. However, coping strategies, including acceptance, proactive mindset, character growth, spirituality, and parent support networks, fostered wellbeing. Conclusion: Both intrapersonal and interpersonal protective processes were important. The findings suggested that Seligman’s (2011) PERMA framework may be applicable to understanding parental wellbeing. Clinical, policy, and research suggestions were discussed

Sociocultural values, attitudes and risk factors associated with adolescent cyberbullying in East Asia: a systematic review

Cyberbullying amongst adolescents is a rapidly growing and alarming global phenomenon that can significantly harm their well-being. Studying cyberbullying in East Asia is especially important, where peer pressure based on collectivistic ideals and rigid cultural scripts for social interactions remain strong. Furthermore, the countries represented in this review are amongst the top globally for internet usage, suggesting that adolescents in East Asia are likely to be excessive users of social media communication and be more exposed to various forms of cyberbullying. This systematic review summarizes findings from peer-reviewed journal articles and book chapters on cyberbullying amongst adolescents between the ages of 10 and 19 in East Asian countries (N = 21). SCOPUS, Google Scholar, and PsycINFO databases were searched for relevant work published between 2008 and 2020. Search strategies involved using keywords related to cyberbullying, adolescents, East Asia, and the name of each country represented in the region (China, South Korea, Japan, Hong Kong and Taiwan). Key factors associated with cyberbullying specific to adolescents in this region are identified and discussed in this review, such as gender socialization patterns and literacy with digital media communication, emphasis on academic achievement and school factors, urban-rural digital divide, relationship with parents and teachers, and collectivistic values. The present review highlights the need to pay further attention to the sociocultural context in future cyberbullying research and calls for more context-specific cyberbullying prevention programs and awareness initiatives

Associations between cardiorespiratory fitness, physical activity and clustered cardiometabolic risk in children and adolescents: the HAPPY study

Clustering of cardiometabolic risk factors can occur during childhood and predisposes individuals to cardiometabolic disease. This study calculated clustered cardiometabolic risk in 100 children and adolescents aged 10-14 years (59 girls) and explored differences according to cardiorespiratory fitness (CRF) levels and time spent at different physical activity (PA) intensities. CRF was determined using a maximal cycle ergometer test, and PA was assessed using accelerometry. A cardiometabolic risk score was computed as the sum of the standardised scores for waist circumference, blood pressure, total cholesterol/high-density lipoprotein ratio, triglycerides and glucose. Differences in clustered cardiometabolic risk between fit and unfit participants, according to previously proposed health-related threshold values, and between tertiles for PA subcomponents were assessed using ANCOVA. Clustered risk was significantly lower (p < 0.001) in the fit group (mean 1.21 ± 3.42) compared to the unfit group (mean -0.74 ± 2.22), while no differences existed between tertiles for any subcomponent of PA. Conclusion These findings suggest that CRF may have an important cardioprotective role in children and adolescents and highlights the importance of promoting CRF in youth

Composite Higgs Sketch

The coupling of a composite Higgs to the standard model fields can deviate substantially from the standard model values. In this case perturbative unitarity might break down before the scale of compositeness is reached, which would suggest that additional composites should lie well below this scale. In this paper we account for the presence of an additional spin 1 custodial triplet of rhos. We examine the implications of requiring perturbative unitarity up to the compositeness scale and find that one has to be close to saturating certain unitarity sum rules involving the Higgs and the rho couplings. Given these restrictions on the parameter space we investigate the main phenomenological consequences of the spin 1 triplet. We find that they can substantially enhance the Higgs di-photon rate at the LHC even with a reduced Higgs coupling to gauge bosons. The main existing LHC bounds arise from di-boson searches, especially in the experimentally clean channel where the charged rhos decay to a W-boson and a Z, which then decay leptonically. We find that a large range of interesting parameter space with 700 GeV < m(rho) < 2 TeV is currently experimentally viable.Comment: 37 pages, 12 figures; v4: sum rule corrected, conclusions unchange

Cognitive and behavioral predictors of light therapy use

Objective: Although light therapy is effective in the treatment of seasonal affective disorder (SAD) and other mood disorders, only 53-79% of individuals with SAD meet remission criteria after light therapy. Perhaps more importantly, only 12-41% of individuals with SAD continue to use the treatment even after a previous winter of successful treatment. Method: Participants completed surveys regarding (1) social, cognitive, and behavioral variables used to evaluate treatment adherence for other health-related issues, expectations and credibility of light therapy, (2) a depression symptoms scale, and (3) self-reported light therapy use. Results: Individuals age 18 or older responded (n = 40), all reporting having been diagnosed with a mood disorder for which light therapy is indicated. Social support and self-efficacy scores were predictive of light therapy use (p's<.05). Conclusion: The findings suggest that testing social support and self-efficacy in a diagnosed patient population may identify factors related to the decision to use light therapy. Treatments that impact social support and self-efficacy may improve treatment response to light therapy in SAD. © 2012 Roecklein et al

A novel emergency department based prevention intervention program for people living with HIV: evaluation of early experiences

<p>Abstract</p> <p>Background</p> <p>HIV prevention is increasingly focused on people living with HIV (PLWH) and the role of healthcare settings in prevention. Emergency Departments (EDs) frequently care for PLWH, but do not typically endorse a prevention mission. We conducted a pilot exploratory evaluation of the first reported ED program to address the prevention needs of PLWH.</p> <p>Methods</p> <p>This retrospective observational cohort evaluation reviewed program records to describe the first six months of participants and programmatic operation. Trained counselors provided a risk assessment and counseling intervention combined with three linkage interventions: i) linkage to health care, ii) linkage to case management, and iii) linkage to partner counseling and referral.</p> <p>Results</p> <p>Of 81 self-identified PLWH who were approached, 55 initially agreed to participate. Of those completing risk assessment, 17/53 (32%, 95 CI 20% to 46%) reported unprotected anal/vaginal intercourse or needle sharing in the past six months with a partner presumed to be HIV negative. Counseling was provided to 52/53 (98%). For those requesting services, 11/15 (73%) were linked to healthcare, 4/23 (17%) were coordinated with case management, and 1/4 (25%) completed partner counseling and referral.</p> <p>Conclusion</p> <p>Given base resources of trained counselors, it was feasible to implement a program to address the prevention needs for persons living with HIV in an urban ED. ED patients with HIV often have unmet needs which might be addressed by improved linkage with existing community resources. Healthcare and prevention barriers for PLWH may be attenuated if EDs were to incorporate CDC recommended prevention measures for healthcare providers.</p

Vascular responses of the extremities to transdermal application of vasoactive agents in Caucasian and African descent individuals

This is an accepted manuscript of an article published by Springer in European Journal of Applied Physiology on 04/04/2015, available online: https://doi.org/10.1007/s00421-015-3164-2 The accepted version of the publication may differ from the final published version.© 2015, Springer-Verlag Berlin Heidelberg. Purpose: Individuals of African descent (AFD) are more susceptible to non-freezing cold injury than Caucasians (CAU) which may be due, in part, to differences in the control of skin blood flow. We investigated the skin blood flow responses to transdermal application of vasoactive agents. Methods: Twenty-four young males (12 CAU and 12 AFD) undertook three tests in which iontophoresis was used to apply acetylcholine (ACh 1 w/v %), sodium nitroprusside (SNP 0.01 w/v %) and noradrenaline (NA 0.5 mM) to the skin. The skin sites tested were: volar forearm, non-glabrous finger and toe, and glabrous finger (pad) and toe (pad). Results: In response to SNP on the forearm, AFD had less vasodilatation for a given current application than CAU (P = 0.027–0.004). ACh evoked less vasodilatation in AFD for a given application current in the non-glabrous finger and toe compared with CAU (P = 0.043–0.014) with a lower maximum vasodilatation in the non-glabrous finger (median [interquartile], AFD n = 11, 41[234] %, CAU n = 12, 351[451] %, P = 0.011) and non-glabrous toe (median [interquartile], AFD n = 9, 116[318] %, CAU n = 12, 484[720] %, P = 0.018). ACh and SNP did not elicit vasodilatation in the glabrous skin sites of either group. There were no ethnic differences in response to NA. Conclusion: AFD have an attenuated endothelium-dependent vasodilatation in non-glabrous sites of the fingers and toes compared with CAU. This may contribute to lower skin temperature following cold exposure and the increased risk of cold injuries experienced by AFD.Published versio

Cosmic Flows on 100 Mpc/h Scales: Standardized Minimum Variance Bulk Flow, Shear and Octupole Moments

The low order moments, such as the bulk flow and shear, of the large scale peculiar velocity field are sensitive probes of the matter density fluctuations on very large scales. In practice, however, peculiar velocity surveys are usually sparse and noisy, which can lead to the aliasing of small scale power into what is meant to be a probe of the largest scales. Previously, we developed an optimal ``minimum variance'' (MV) weighting scheme, designed to overcome this problem by minimizing the difference between the measured bulk flow (BF) and that which would be measured by an ideal survey. Here we extend this MV analysis to include the shear and octupole moments, which are designed to have almost no correlations between them so that they are virtually orthogonal. We apply this MV analysis to a compilation of all major peculiar velocity surveys, consisting of 4536 measurements. Our estimate of the BF on scales of ~ 100 Mpc/h has a magnitude of |v|= 416 +/- 78 km/s towards Galactic l = 282 degree +/- 11 degree and b = 6 degree +/- 6 degree. This result is in disagreement with LCDM with WMAP5 cosmological parameters at a high confidence level, but is in good agreement with our previous MV result without an orthogonality constraint, showing that the shear and octupole moments did not contaminate the previous BF measurement. The shear and octupole moments are consistent with WMAP5 power spectrum, although the measurement noise is larger for these moments than for the BF. The relatively low shear moments suggest that the sources responsible for the BF are at large distances.Comment: 13 Pages, 7 figures, 4 tables. Some changes to reflect the published versio
