A systematic review of three approaches for constructing physical activity messages: What messages work and what improvements are needed?
<p>Abstract</p> <p>Background</p> <p>To motivate individuals to adhere to a regular physical activity regime, guidelines must be supplemented with persuasive messages that are disseminated widely. While substantial research has examined effective strategies for disseminating physical activity messages, there has been no systematic effort to examine optimal message content. This paper reviews studies that evaluate the effectiveness of three approaches for constructing physical activity messages including tailoring messages to suit individual characteristics of message recipients (message tailoring), framing messages in terms of gains versus losses (message framing), and targeting messages to affect change in self-efficacy (i.e., a theoretical determinant of behavior change).</p> <p>Methods</p> <p>We searched the MEDLINE, PsycINFO, EMBASE and CINAHL databases up to July 2008. Relevant reference lists also were searched. We included intervention trials, field experiments, and laboratory-based studies that aimed to test the efficacy or effectiveness of tailored messages, framed messages and self-efficacy change messages among healthy adults. We used a descriptive approach to analyze emerging patterns in research findings. Based on this evidence we made recommendations for practice and future research.</p> <p>Results</p> <p>Twenty-two studies were identified. Twelve studies evaluated message tailoring. In 10 of these studies, tailored messages resulted in greater physical activity than a control message. Six studies evaluated framed messages. Five of these studies demonstrated that gain-framed messages lead to stronger intentions to be active compared to a control message. Moreover, a gain-frame advantage was evident in three of the four studies that assessed physical activity. Four studies evaluated self-efficacy change messages. The two studies that used an experimental design provide a clear indication that individuals' beliefs can be affected by messages that incorporate types of information known to be determinants of self-efficacy. Overall, strong evidence to support definitive recommendations for optimal message content and structure was lacking.</p> <p>Conclusions</p> <p>Additional research testing the optimal content of messages used to supplement physical activity guidelines is needed. Tailored messages, gain-framed messages, and self-efficacy change messages hold promise as strategies for constructing physical activity messages and should be a focus of future research.</p
Cohort profile: the Right to Care Clinical HIV Cohort, South Africa
PURPOSE: The research objectives of the Right to Care Clinical HIV Cohort analyses are to: (1) monitor treatment outcomes (including death, loss to follow-up, viral suppression and CD4 count gain among others) for patients on antiretroviral therapy (ART); (2) evaluate the impact of changes in the national treatment guidelines around when to initiate ART on HIV treatment outcomes; (3) evaluate the impact of changes in the national treatment guidelines around what ART regimens to initiate on drug switches; (4) evaluate the cost and cost-effectiveness of HIV treatment delivery models; (5) evaluate the need for and outcomes on second-line and third-line ART; (6) evaluate the impact of comorbidity with non-communicable diseases on HIV treatment outcomes and (7) evaluate the impact of the switch to initiating all patients onto ART regardless of CD4 count.
PARTICIPANTS: The Right to Care Clinical HIV Cohort is an open cohort of data from 10 clinics in two provinces within South Africa. All clinics include data from 2004 onwards. The cohort currently has data on over 115 000 patients initiated on HIV treatment and patients are followed up every 3–6 months for clinical and laboratory monitoring.
FINDINGS TO DATE: Cohort data includes information on demographics, clinical visit, laboratory data, medication history and clinical diagnoses. The data have been used to identify rates and predictors of first-line failure, to identify predictors of mortality for patients on second-line (eg, low CD4 counts) and to show that adolescents and young adults are at increased risk of unsuppressed viral loads compared with adults.
FUTURE PLANS: Future analyses will inform national models of HIV care and treatment to improve HIV care policy in South Africa

How trainee physical education teachers in England write, use and evaluate lesson plans
Traditionally, all physical education initial teacher training (PEITT) courses in England, and in many other countries, require trainee teachers to complete detailed lesson plans for each lesson they teach in their school-based practicum and then to evaluate those lessons. However, there has been a limited amount of research on lesson planning in PEITT generally or in England specifically. The purpose of this study therefore was to gain an initial insight into how trainee physical education teachers write, use and evaluate lesson plans. Two-hundred-and-eighty-nine physical education trainees in England completed a questionnaire about lesson planning after finishing a block school-based practicum. Frequencies and percentages were calculated for the limited-choice questions on the questionnaires and open-ended questions were analysed using thematic analysis. Results showed mixed responses, with no one method followed by all trainees. Some trainees stated they planned and/or evaluated lessons as taught. Some stated they completed the plan and/or evaluation proforma to ‘tick a box’. The highest percentage of trainees stated it took between half an hour and one-and-a-half hours to plan each lesson. Although most trainees stated they found the plan useful in the lesson, others stated they found it too detailed to use. Some stated they did not deviate from the plan in the lesson, whereas others adapted the plan. The majority of trainees stated that evaluation enabled them to see if objectives had been achieved. Results are discussed in relation to teaching trainees how to plan lessons in PEITT in England
