Smoking cessation programs in pregnancy: systematically addressing development, implementation, women's concerns and effectiveness

Objectives:  To increase a review's relevance to practitioners and service users and identify the implications for systematic review methodology. Methods:  A systematic review of the effects of smoking cessation programmes implemented during pregnancy integrated process indicators and the views of maternity service users and health promotion specialists. Additional qualitative data were extracted systematically from included randomised control trials (RCTs) to determine whether the design of interventions and conclusions arising from their evaluation related to the views of service users. On completing the review we reflected on the types of observational and qualitative research it drew on, where this research was incorporated into the review, and its added value. Results:   Incorporating process indicators into the review revealed: 1) problems with implementation and transplantation of some interventions and 2) studies with more stringent quality criteria and process evaluations demonstrated greater impact (weighted mean difference in smoking). Pregnant smokers were rarely involved in the design or evaluation of the interventions. Prior observational and qualitative studies and small scale consultations influenced the criteria by which the effectiveness of the interventions were judged, and revealed to what extent these criteria are adopted in practice.
Conclusions:   Systematically abstracting data about the development and delivery of interventions revealed gaps that might be filled by the active involvement of service users.

Preventing childhood obesity : the sentinel site for obesity prevention in Victoria, Australia

In spite of greater awareness of the need for action to reduce obesity, the evidence on sustainable community approaches to prevent childhood and adolescent obesity is surprisingly sparse. This paper describes the design and methodological components of the Sentinel Site for Obesity Prevention, a demonstration site in the Barwon-South West region of Victoria, Australia, that aims to build the programs, skills and evidence necessary to attenuate and eventually reverse the obesity epidemic in children and adolescents.

The Sentinel Site for Obesity Prevention is based on a partnership between the region's university (Deakin University) and its health, education and local government agencies. The three basic foundations of the Sentinel Site are: multi-strategy, multi-setting interventions; building community capacity; and undertaking program evaluations and population monitoring. Three intervention projects have been supported that cover different age groups (preschool: 2–5 years, primary school: 5–12 years, secondary school: 13–17 years), but that have many characteristics in common including: community participation and ownership of the project; an intervention duration of at least 3 years; and full evaluations with impact (behaviours) and outcome measures (anthropometry) compared with regionally representative comparison populations.

We recommend the Sentinel Site approach to others for successfully building evidence for childhood obesity prevention and stimulating action on reducing the epidemic.

Unrealistic optimism and event threat

Individuals typically exhibit “unrealistic optimism” (UO), the belief that they are less likely than the average person to experience a negative event. This may be because, fearing the event, they try to reassure themselves by distorting their reasoning to conclude that they are at comparatively little risk. If this is so, the greater the “event threat” (i.e., the more serious the event's consequences and/or the greater the likelihood that those consequences will be experienced), the more reassurance should be required, and the greater the UO that should be observed. This prediction was tested in a study in which students (N = 148) were informed about a type of heart disease that could develop in later life due to inadequate diet when young. The risk attributable to diet was stated to be either slight (low-threat condition) or great (high-threat condition). Participants were asked to rate their own risk and that of the average student of developing the disease; question order was counterbalanced. The effects of event threat and question order were found to interact: event threat affected UO in the predicted way, but only when the question about own risk came first. The results are explained in motivational terms. Implications for health education are discussed.

Weighing it up : thinking about the implications of school based obesity prevention initiatives

In this paper we explore the tensions that exist between two health promotion discourses prevalent in school based Health Education. We use one example from a widely used curriculum resource and one classroom episode to explore discourses related to obesity prevention, often described as an obesity epidemic by media and health professionals alike. Our argument is that these discourses work to produce the 'unhealthy other' that everyone is then in danger of becoming and in the process produce moral judgements and reinforce stereotypes about overweight and obese people. In so doing they run counter to health education and other discourses that seek to promote self-esteem and body acceptance in students no matter what their shape and size.

Clinical placement and rurality of career commencement : a pilot study

This article reports on a project that aimed to discover whether rural placement can influence new graduates to take up rural positions, and what factors play a role in the decision-making. This pilot study reports the findings from a pre-survey of students (n = 110) who completed a questionnaire at the end of their rural placement in the Greater Green Triangle region, Australia. Findings are compared with matched questionnaire responses for students who subsequently completed a post-survey after graduation and who commenced work (n = 28). Rural placement appears to be associated with commencing rural practice after graduation. More graduates with an urban home address commenced rural practice than graduates with a rural home address who started their careers in the city. Longer placements may sway those with a city background to start work in a rural area.

Why do medical graduates choose rural careers?

Introduction: This study is based on the metaphor of the ‘rural pipeline’ into medical practice. The four stages of the rural
pipeline are: (1) contact between rural secondary schools and the medical profession; (2) selection of rural students into medical
programs; (3) rural exposure during medical training; and (4) measures to address retention of the rural medical workforce.
Methods: Using the rural pipeline template we conducted a literature review, analysed the selection methods of Australian
graduate entry medical schools and interviewed 17 interns about their medical career aspirations.
Results: Literature review: The literature was reviewed to assess the effectiveness of selection practices to predict successful
gradation and the impact of rural pipeline components on eventual rural practice. Undergraduate academic performance is the
strongest predictor of medical course academic performance. The predictive power of interviews is modest. There are limited data
on the predictive power of other measures of non-cognitive performance or the content of the undergraduate degree. Prior rural
residence is the strongest predictor of choice of a rural career but extended rural exposure during medical training also has a
significant impact. The most significant influencing factors are: professional support at national, state and local levels; career
pathway opportunities; contentedness of the practitioner’s spouse in rural communities; preparedness to adopt a rural lifestyle;
educational opportunities for children; and proximity to extended family and social circle. Analysis of selection methods: Staff
involved in student selection into 9 Australian graduate entry medical schools were interviewed. Four themes were identified:
(1) rurality as a factor in student selection; (2) rurality as a factor in student selection interviews; (3) rural representation on student
selection interview panels; (4) rural experience during the medical course. Interns’ career intentions: Three themes were identified:
(1) the efficacy of the rural pipeline; (2) community connectedness through the rural pipeline; (3) impediments to the effect of the
rural pipeline, the most significant being a partner who was not committed to rural life
Conclusion: Based on the literature review and interviews, 11 strategies are suggested to increase the number of graduates
choosing a career in rural medicine, and one strategy for maintaining practitioners in rural health settings after graduation.

Change of perspective: a measurable and desired outcome of chronic disease self-management intervention programs that violates the premise of preintervention/postintervention assessment

Objective: To determine if participants in chronic disease self-management courses have a change of perspective of their health status (a response shift), and if this is measurable with a paper-based questionnaire.

Methods: Nine items were developed to measure potential benefits of self-management courses. These were based on the constructs of a previous questionnaire, the Health Education Impact Questionnaire (HEI-Q). Cognitive interviews elicited spontaneous statements about the reasons for paper-based answers. Sensitivity, specificity, and overall accuracy of items were calculated using the interview as a relative gold standard. Response shift can be negative (i.e., after the course, participants realize that, before the course, they were worse than they thought they were), positive (i.e., participants now realize they were better than they thought they were), or absent (no change).

Results: Interviews (n = 39) reflected that true response shift occurred in approximately half the replies to questionnaire items. Of these, 31% were negative response shift, 20% were positive response shift. Response shift was absent in 32% of replies. Presence or absence of response shift could not be determined in 17% of replies across items. Significant concordance between questionnaires and cognitive interviews (average overall accuracy 0.79) indicated that the HEI-Q Perspective questionnaire detects response shift in participants of self-management courses. The questionnaire revealed that 87% of participants had response shift in at least 1 item.

Conclusion: This study suggests that preintervention/postintervention assessments of interventions such as self-management courses are confounded by a change in perspective of a large proportion of respondents. It also indicates response shift is a valuable outcome of self-management courses that can be measured with a paper-based questionnaire.

Sexualities and gender in the classroom : changing teacher practice

Despite significant changes in policy and practice, same-sex attracted young people in Australian schools continue to experience high levels of abuse and violence.  The majority of schools are at worst openly homophobic and at least neglectful.  There is a reluctance by health education teachers to recognise and affirm gender and sexual diversity.  This book examines the challenging process teachers go through as they gain the skills needed to be more inclusive in their teaching.  In the context of anew professional learning program, the journey of 14 diverse, yet characteristic, health education teachers is documented and analysed.  The study concludes that whilst there is a range ofpersonal and structural barriers inhibiting change, teachers were nabled to implement many aspects of their professional learning through supported risk-taking.  The findings and analysis will be of itnerst to academics and professionals in health and sexuality education and to those working in health and sexuality education more broadly.

Ein Blick Down Under. Selbstmanagementinitiativen und Patientenschulungen in Australien

The growing burden of chronic disease and the current nature of healthcare systems which are structurally ill-equipped to cater to the complex needs of patients with chronic conditions has led to governments and healthcare providers seeking alternative ways to improve patients own capacity to actively self-manage their chronic condition. In Australia, there has been a focus on patient education and self-management programs within the healthcare system to achieve this. These programs aim to empower patients through providing information and teaching skills and techniques to improve self-care and doctor-patient interaction with the ultimate goal of improving quality of life. Patient education and self-management programs have been supported through several national government initiatives and implemented within the healthcare setting. This paper describes the current position of patient education and self-management within the Australian healthcare system. It further describes a new collaboration project between an Australian and a German research team which aims at translating an assessment questionnaire used in Australia for the evaluation of self-management programs, the “Health Education Impact Questionnaire” (“heiQ”); this instrument is expected to be of significant use in the German rehabilitative system.

Tests of measurement invariance failed to support the application of the "then-test"

Objective
The use of then-test (retrospective pre-test) scores has frequently been proposed as a solution to potential confounding of change scores because of response shift, as it is assumed that then-test and post-test responses are provided from the same perspective. However, this assumption has not been formally tested using robust quantitative methods. The aim of this study was to compare the psychometric performance of then-test/post-test with traditional pre-test/post-test data and assessing whether the resulting data structures support the application of the then-test for evaluations of chronic disease self-management interventions.

Study Design and Setting
Pre-test, post-test, and then-test data were collected from 314 participants of self-management courses using the Health Education Impact Questionnaire (heiQ). The derived change scores (pre-test/post-test; then-test/post-test) were examined for their psychometric performance using tests of measurement invariance.

Results
Few questionnaire items were noninvariant across pre-test/post-test, with four items identified and requiring removal to enable an unbiased comparison of factor means. In contrast, 12 items were identified and required removal in then-test/post-test data to avoid biased change score estimates.

Conclusion
Traditional pre-test/post-test data appear to be robust with little indication of response shift. In contrast, the weaker psychometric performance of then-test/post-test data suggests psychometric flaws that may be the result of implicit theory of change, social desirability, and recall bias.

Weight, physical activity and dietary behavior change in young mothers : short term results of the HeLP-her cluster randomized controlled trial

Background
Preventing weight gain rather than treating established obesity is an important economic and public health response to the rapidly increasing rates of obesity worldwide. Treatment of established obesity is complex and costly requiring multiple resources. Preventing weight gain potentially requires fewer resources to reach broad population groups, yet there is little evidence for successful interventions to prevent weight gain in the community. Women with children are an important target group because of high rates of weight gain and the potential to influence the health behaviors in family members.

Methods
The aim of this cluster randomized controlled trial was to evaluate the short term effect of a community-based self-management intervention to prevent weight gain. Two hundred and fifty mothers of young children (mean age 40 years ± 4.5, BMI 27.9 kg/m2 ± 5.6) were recruited from the community in Melbourne, Australia. The intervention group (n = 127) attended four interactive group sessions over 4 months, held in 12 local primary schools in 2006, and was compared to a group (n = 123) receiving a single, non-interactive, health education session. Data collection included self-reported weight (both groups), measured weight (intervention only), self-efficacy, dietary intake and physical activity.

Results
Mean measured weight decreased significantly in the intervention group (-0.78 kg 95% CI; -1.22 to -0.34, p < 0.001). Comparing groups using self-reported weight, both the intervention and comparison groups decreased weight, -0.75 kg (95% CI; -1.57 to 0.07, p = 0.07) and -0.72 kg (95% CI; -1.59 to 0.14 p = 0.10) respectively with no significant difference between groups (-0.03 kg, 95% CI; -1.32 to 1.26, p = 0.95). More women lost or maintained weight in the intervention group. The intervention group tended to have the greatest effect in those who were overweight at baseline and in those who weighed themselves regularly. Intervention women who rarely self-weighed gained weight (+0.07 kg) and regular self-weighers lost weight (-1.66 kg) a difference of -1.73 kg (95% CI; -3.35 to -0.11 p = 0.04). The intervention reported increased physical activity although the difference between groups did not reach significance. Both groups reported replacing high fat foods with low fat alternatives and self-efficacy deteriorated in the comparison group only.

Conclusion
Both a single health education session and interactive behavioral intervention will result in a similar weight loss in the short term, although more participants in the interactive intervention lost or maintained weight. There were small non-significant changes to physical activity and changes to fat intake specifically replacing high fat foods with low fat alternatives such as fruit and vegetables. Self-monitoring appears to enhance weight loss when part of an intervention.
