Weight Loss Strategies Associated With BMI in Overweight Adults With Type 2 Diabetes at Entry Into the Look AHEAD (Action for Health in Diabetes) Trial

OBJECTIVE—Intentional weight loss is recommended for those with type 2 diabetes, but the strategies patients attempt and their effectiveness for weight management are unknown. In this investigation we describe intentional weight loss strategies used and those related to BMI in a diverse sample of overweight participants with type 2 diabetes at enrollment in the Look AHEAD (Action for Health in Diabetes) clinical trial

Interactive acquisition and sharing: Understanding the dynamics of HIV/AIDS information networks

HIV/AIDS information is an important resource for people affected by the disease, particularly information that they obtain from other people. Although existing studies reveal that people with HIV/AIDS (PHAs) rely extensively on personal relationships for HIV/AIDS information, they explain little about how this happens as a social process. To investigate how PHAs and their friends/family members acquire and share network-mediated HIV/AIDS information, semistructured, in-depth interviews were conducted in three rural regions of Canada. Interviews were carried out with 114 PHAs, their friends/family members, and health care and service providers. A network solicitation and chain-referral recruitment procedure was used to delineate HIV/AIDS information networks for participants. Interview data were analyzed qualitatively and compared to Haythornthwaite's ( 1996 ) concepts of network-mediated information processes and Talja and Hansen's ( 2006 ) collaborative information behavior framework. Findings revealed that participants obtained HIV/AIDS information from their networks through five interactive processes: joint seeking, tag-team seeking, exposure, opportunity, and legitimation. The results of this study advance information behavior theory by pointing to the interactive character of information behavior and introducing new concepts to describe everyday life collaborative information behavior. This research also demonstrates the extensive interplay between health information exchange and the sharing of emotional support. The insights emanating from this study suggest that health information practice might benefit from a focus on program strategies such as building information network capacity, developing collaborative information retrieval systems and relationship-building, in addition to the more traditional library-related concerns of reference encounters, collections, and institutional Web sites.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/64304/1/21151_ftp.pd

Internet-based treatment for older adults with depression and co-morbid cardiovascular disease: protocol for a randomised, double-blind, placebo controlled trial

<p>Abstract</p> <p>Background</p> <p>Depression, cardiovascular disease (CVD) risk factors and cognitive impairment are important causes of disability and poor health outcomes. In combination they lead to an even worse prognosis. Internet or web-based interventions have been shown to deliver efficacious psychological intervention programs for depression on a large scale, yet no published studies have evaluated their impact among patients with co-existing physical conditions. The aims of this randomised controlled trial are to determine the effects of an evidence-based internet intervention program for depression on depressive mood symptoms, cognitive function and treatment adherence in patients at risk of CVD.</p> <p>Methods/Design</p> <p>This study is an internet-based, double-blind, parallel group randomised controlled trial. The trial will compare the effectiveness of online cognitive behavioural therapy with an online attention control placebo. The trial will consist of a 12-week intervention phase with a 40-week follow-up. It will be conducted in urban and rural New South Wales, Australia and will recruit a community-based sample of adults aged 45 to 75 years. Recruitment, intervention, cognitive testing and follow-up data collection will all be internet-based and automated. The primary outcome is a change in severity of depressive symptoms from baseline to three-months. Secondary outcomes are changes in cognitive function and adherence to treatment for CVD from baseline to three, six and 12-months.</p> <p>Discussion</p> <p>Prior studies of depression amongst patients with CVD have targeted those with previous vascular events and major depression. The potential for intervening earlier in these disease states appears to have significant potential and has yet to be tested. Scalable psychological programs using web-based interventions could deliver care to large numbers in a cost effective way if efficacy were proved. This study will determine the effects of a web-based intervention on depressive symptoms and adherence to treatment among patients at risk of CVD. In addition it will also precisely and reliably define the effects of the intervention upon aspects of cognitive function that are likely to be affected early in at risk individuals, using sensitive and responsive measures.</p> <p>Trial registration</p> <p>Australian New Zealand Clinical Trials Registry (ANZCTR): <a href="http://www.anzctr.org.au/ACTRN12610000085077.aspx">ACTRN12610000085077</a></p

Performance Milestones in the Development of Expertise: Are They Critical?

Fifty-seven female netballers completed a training history profile to examine whether the achievement of performance milestones and/or accumulation of sport-specific practice were indicative of an athlete&#039;s level of expertise. Similar to previous research, results revealed that expert and developmental athletes accumulated a greater number of hours in netball-specific practice relative to the recreational participants, but did not differ in the number of sports played or hours accumulated in non-netball specific practice. Interestingly, some performance milestones were achieved by the expert and developmental athletes earlier than the recreational participants, however, the developmental athletes achieved a number of milestones at an earlier age than the experts. These findings are discussed in relation to contemporary models of skill development, namely deliberate practice (Ericsson, Krampe, &amp; Tesch-Römer, 1993) and the developmental model of sport participation (Côté, 1999) and the underpinning socio-environmental factors that may influence sport participation and subsequent development of expertise

How specific is domain specificity: Does it extend across playing position?

The current study examined positional specificity effects within the sport of netball. Netball is a relatively unique sport because players are zoned in the areas into which they can move (goaler, centre court and defence). Thus if specificity effects do occur, they would be expected in a sport such as netball as players typically only play within one region of the court and do so from a relatively early stage of their career. Skilled and novice netballers completed a video-based decision making task that presented scenarios they would commonly experience in their own position as well as the other remaining playing areas (goaler, centre court and defence). It was hypothesised, in line with previous research, that the skilled players would have greater decision making accuracy than the novice participants due to their greater netball specific experiences.14 Additionally, it was hypothesised that the skilled athletes would demonstrate a position specificity bias and consequently be most accurate on the scenarios from which they are most familiar with, namely their own positional area due to the development of specific memory representations for the task,7 whereas the novice participants would show no positional biases due to their limited netball experience

Discriminating talent-identified junior Australian football players using a video decision-making task

This study examined if a video decision-making task could discriminate talent-identified junior Australian football players from their non-talent-identified counterparts. Participants were recruited from the 2013 under 18 (U18) West Australian Football League competition and classified into two groups: talent-identified (State U18 Academy representatives; n = 25; 17.8 ± 0.5 years) and non-talent-identified (non-State U18 Academy selection; n = 25; 17.3 ± 0.6 years). Participants completed a video decision-making task consisting of 26 clips sourced from the Australian Football League game-day footage, recording responses on a sheet provided. A score of &quot;1&quot; was given for correct and &quot;0&quot; for incorrect responses, with the participants total score used as the criterion value. One-way analysis of variance tested the main effect of &quot;status&quot; on the task criterion, whilst a bootstrapped receiver operating characteristic (ROC) curve assessed the discriminant ability of the task. An area under the curve (AUC) of 1 (100%) represented perfect discrimination. Between-group differences were evident (P &lt; 0.05) and the ROC curve was maximised with a score of 15.5/26 (60%) (AUC = 89.0%), correctly classifying 92% and 76% of the talent-identified and non-talent-identified participants, respectively. Future research should investigate the mechanisms leading to the superior decision-making observed in the talent-identified group

But I can’t pass that far! The influence of motor skill on decision making

Objectives: The influence of motor skill on perceptual-cognitive and perceptual-motor decision making has been theorised but not verified empirically. Method: Expert (n = 19), developmental (n = 20), and lesser-skilled netballers (n = 19) completed tests designed to evaluate three different components of domain-specific expertise: (i) motor skill-execution; (ii) perceptual-cognitive decision making; and (iii) perceptual-motor decision making. Results: Each of the three measures was found to improve commensurate with domain-specific skill. Decisions requiring movements (perceptual-motor) elicited more accurate decision making than simple verbal responses (perceptual-cognitive), irrespective of participant skill. Although motor skill was found to be related to the successful execution of a most appropriate movement in a game situation, it was not found to limit the nature of the decision made by participants. No evidence was found to support the supposition that lesser-skilled participants bias their perceptual-cognitive decisions towards ones supported by their motor ability. Conclusions: Results fail to comprehensively support the contemporary models for the development of perceptual-cognitive and perceptual-motor skill in sport
