Employing the theory of planned behaviour to design an e-cigarette education resource for use in secondary schools.

BACKGROUND: An extended version of the theory of planned behaviour (TPB) was used to inform the design of a framework for an educational resource around e-cigarette use in young people. METHODS: A sequential exploratory design was employed. In Phase 1, elicited behavioural, normative and control beliefs, via 7 focus groups with 51 participants, aged 11-16 years, identified salient beliefs around e-cigarette use. These were used to construct a questionnaire administered to 1511 young people aged 11-16 years, which determined predictors of e-cigarette use and ever use. In Phase 2, sociodemographic variables, e-cigarette knowledge, access, use, marketing and purchasing of e-cigarettes and smoking behaviour were also gathered. The composite findings from Phase 1 and 2 informed the design of a post primary educational resource in Phase 3 around e-cigarette use. RESULTS: Current e-cigarette use was 4%, with almost 23% reporting ever use, suggesting current use is stable but experimentation may be increasing in this cohort. Sociodemographic variables, knowledge of e-cigarettes, smoking behaviour and TPB variables (direct and indirect measures of attitudes, subjective norm, and perceived behavioural control) accounted for 17% of the variance in current e-cigarette use, with higher intentions to use e-cigarettes within the next month, having the strongest impact on use (p < 0.001), followed by self-efficacy (p = 0.016). Sociodemographic and TPB variables accounted for 65% of the variance in intentions to use e-cigarettes in the next month; current e-cigarette use (p < 0.001), more positive attitudes (p < 0.001), stronger social influence (p < 0.001), higher self-efficacy (p < 0.001), higher control beliefs (p < 0.001) and greater motivation to use e-cigarettes (p < 0.001) were the main predictors of intentions. Phases 1 and 2 informed the mapping of key predictors of intentions and use of e-cigarettes onto the Theoretical Domains Framework, which identified appropriate intervention functions and behaviour change techniques. CONCLUSIONS: This paper is the first to bridge the theoretical-practice gap in an area of significant public health importance through the development of a framework for a novel theory driven school-based educational resource aimed at reducing experimentation and uptake of e-cigarette use in young people.

Translation research: 'Back on Track', a multiprofessional rehabilitation service for cancer-related fatigue.

OBJECTIVES: To assess the effectiveness and acceptability of an individually tailored rehabilitation intervention for patients with cancer-related fatigue (CRF). METHODS: Eighteen individuals, (16 female, two male, aged 40-83 years), who self-reported CRF (above four on a 10-point Likert scale) took part in an 8 week physical activity intervention weekly review and optional gym-based support. Fifteen participants had a primary diagnosis of breast cancer and along with the other participants had multiple myeloma, colorectal or prostate cancer. All participants took part in a goal-oriented walking and muscle strengthening programme with dietary advice and psychological support based on the Transtheoretical Model (TTM) of behaviour change. Effectiveness was assessed by physical and psychological outcomes. Focus groups with participants and individual interviews with the professionals delivering the intervention explored the feasibility and acceptability of the intervention. RESULTS: Statistically significant improvements were seen in the primary outcome of fatigue and on the secondary outcomes of physical function, depression and in triceps skin fold thickness reduction. Participants endorsed the intervention as being highly acceptable, holistic and as important as medical treatments for cancer. The importance of team working was highlighted as key to service delivery and success. CONCLUSIONS: A multidisciplinary home-based tailored intervention with optional weekly gym attendance is acceptable to people with CRF, improving physical and psychosocial outcomes. Study limitations and suggestions for further research are discussed.

Exercise and nutrition interventions in advanced lung cancer: a systematic review.

UNLABELLED: In this systematic review, we sought to evaluate the effect of physical activity or nutrition interventions (or both) in adults with advanced non-small-cell lung cancer (nsclc). METHODS: A systematic search for relevant clinical trials was conducted in 6 electronic databases, by hand searching, and by contacting key investigators. No limits were placed on study language. Information about recruitment rates, protocol adherence, patient-reported and clinical outcome measures, and study conclusions was extracted. Methodologic quality and risk of bias in each study was assessed using validated tools. MAIN RESULTS: Six papers detailing five studies involving 203 participants met the inclusion criteria. Two of the studies were single-cohort physical activity studies (54 participants), and three were controlled nutrition studies (149 participants). All were conducted in an outpatient setting. None of the included studies combined physical activity with nutrition interventions. CONCLUSIONS: Our systematic review suggests that exercise and nutrition interventions are not harmful and may have beneficial effects on unintentional weight loss, physical strength, and functional performance in patients with advanced nsclc. However, the observed improvements must be interpreted with caution, because findings were not consistent across the included studies. Moreover, the included studies were small and at significant risk of bias. More research is required to ascertain the optimal physical activity and nutrition interventions in advanced inoperable nsclc. Specifically, the potential benefits of combining physical activity with nutrition counselling have yet to be adequately explored in this population.

What can we learn from the personal insights of individuals living and coping with multiple sclerosis?

PURPOSE: The aim of this qualitative study was to explore the personal accounts of individuals with Multiple Sclerosis (MS). Hence the study presents individuals experiences of living with MS to date and the effective self-management strategies employed to cope in day-to-day life. METHODS: Thematic analysis was used to explore the personal narratives of thirteen individuals with MS in two focus group discussions. RESULTS: Participants in both groups identified similar themes related to the experiences of living and coping with MS. These were: Learning something was wrong (before diagnosis); getting a name (diagnosis); lack of professional support; unchanging family relationships, adjustments to employment circumstances and social life; challenges; successful coping via proactivity, perspective and control (self-management techniques); advice for others, and recommendations as to how services could be improved and developed. CONCLUSION: The most salient finding is that there is a need for a formal approach to the management of psychosocial problems and challenges associated with MS. This will require both users and health professionals working together to further the development of clinical guidelines and services for this population.

Psychosocial interventions in people with multiple sclerosis: a review.

BACKGROUND: Upon diagnosis individuals with Multiple Sclerosis (MS) must cope with both day to day and disease-related stressors in addition to unpredictable, fluctuating and confusing symptoms. Furthermore, disease progression may interfere with employment, family life, relationships and social activities. Psychosocial interventions aim to help individuals manage these psychological, social and emotional challenges. However, there are no specific guidelines available regarding the most effective intervention content, format or delivery. Therefore, a review of the research that has utilised these interventions, specifically those which, by definition, aimed to improve quality of life (QoL) and/or well-being in people with MS, was considered essential in order to identify which aspects of these interventions may help alleviate the psychosocial challenges associated with MS. OBJECTIVES: To identify all randomised controlled trials (RCTs), quasi-experimental, cohort, case control and case series studies that have investigated psychosocial interventions in people with MS which aimed to improve QoL and/or well-being, to establish the methodological quality of such studies, and to determine the effectiveness of the interventions. SEARCH STRATEGY: Searches were carried out using computerised databases with predefined search terms; this was supplemented by manual searches of reference lists of all retrieved articles. Relevant journals were also hand searched. SELECTION CRITERIA: Studies written in English and published before January 2006, investigating the effectiveness of psychosocial interventions on QoL and/or well-being in people with MS, were eligible for inclusion. DATA COLLECTION AND ANALYSIS: Methodological quality was independently assessed by two reviewers using the Downs and Black quality scoring checklist. The qualitative and quantitative characteristics of studies were extracted using a data extraction sheet. MAIN RESULTS: Thirty-three studies fulfilled the inclusion criteria; however, interventions varied widely in content, delivery and duration. Furthermore, failure to report full methodological details, as well as weaknesses in study design, reduced the strength of inferences that could be drawn from these studies. These notwithstanding, there were three studies of sufficient quality to provide some evidence regarding the value of education/information, goal setting, homework assignments, exercise, discussion forums and multidisciplinary team support. Thus, this review has identified the potential benefit of the aforementioned activities in the psychosocial management of this population. However, further well designed clinical trials are warranted to determine, definitively, the effectiveness, or otherwise, of these components.

Patients with head and neck cancer prefer individualized cognitive behavioural therapy.

Cognitive behaviour therapy (CBT) is a widely practiced and approved form of psychotherapy for many psychosocial difficulties. As the efficacy of CBT is recognized, its demand has increased and today exceeds the availability of qualified practitioners. Therefore, the effectiveness of delivering CBT using less labour-intensive modes than individualised therapy has been explored. These include group therapy, bibliotherapy and computer assisted therapy. Given the UK Government's impetus towards patient choice and involvement in the planning of healthcare, it was thought essential to ascertain the preferred delivery mode of patients with head and neck cancer for a CBT based intervention. Therefore, a small retrospective cohort (n= 28) of patients following treatment for head and neck cancer were sent postal questionnaires to ascertain their preferences on mode of CBT delivery. Simultaneously, the views of accredited cognitive behaviour therapists (n= 14) were determined on the optimal mode of CBT delivery to these patients. Findings indicated that patients preferred the more individualized mode of CBT delivery, namely one-to-one therapy, followed closely by bibliotherapy, with group format being the least preferred option. Professionals concurred with patients, in that one-to-one interaction was considered an optimal mode of CBT delivery, but professionals considered it equal to group therapy.

Measuring disability in multiple sclerosis: is the Community Dependency Index an improvement on the Barthel Index?

The Community Dependency Index (CDI) was developed due to concerns that the Barthel Index (BI) was limited as a measure of physical function in community settings. However, no studies have compared the two rating scales within multiple sclerosis (MS). The aim of this study was to determine whether, in a community-based sample of people with MS, the CDI is a better measure than the BI. BI and CDI data were collected from 90 people with MS. Four measurement properties were compared: scaling assumptions (item mean scores, corrected item-total correlations), acceptability (score distributions, floor/ceiling effects), reliability (Cronbach's alpha) and validity (concurrent, discriminant, group differences, relative validity). Both scales satisfied recommended criteria for scaling assumptions (indicating it was legitimate to report a summed score) and internal consistency reliability (alpha > 0.85). The scales were highly correlated (r = 0.96), indicating they measured the same construct. Both scales demonstrated good group differences validity, but the BI was marginally superior. Notable ceiling effects (BI > CDI) were demonstrated for both scales, particularly in those less disabled. This study sample had relatively minor levels of disability, with over 70% still being independently mobile. In this sample of people with MS, the measurement properties of the BI and CDI examined were very similar, suggesting the CDI does not appear to have achieved its goal of better measurement.

Color or brightness effects on grip strength?

Research into the effects of color on grip strength has produced inconsistent results, but studies show methodological problems, for example, the non-standardised reporting of stimulus colours, differing intertrial rests, and the neglect of warm-up effects. The present study was designed to replicate the 1989 work by Hasson, et al. and also to examine potential brightness effects of stimuli on grip strength. Analysis indicated brightness effects might confound potential to produce Type I errors.

Grip strength and intertrial rest.

This experiment illustrates that the 1991 Montazer and Thomas conclusion that grip strength declines over time is incomplete 15 men performed 4 grip-strength trials with intertrial rests of 120 sec. Analysis showed that performance did not decrease over the 4 trials, on the contrary, the pattern was that of a learning curve, with a significant difference across the 4 trials, i.e., on Trial 1 grip strength was lower than on successive trials. Such a result points to the importance of 'warming-up' the muscle to obtain optimum functioning. Also, subjects should be familiar with the task and the equipment to reduce the chance of a Type I error. Implications for research are discussed.

Thoughts on perceptual influences of colored paper.

Much of the material one reads is in black and white. It is proposed that the color of paper may influence perception and performance on pen-and-paper tasks.

Methodological consideration in color research.

Color can influence physical and emotional variables, but the evidence is equivocal. Replications are often hampered by inadequate specification of colored stimuli. It is proposed that a standardized method for reporting colored stimuli should be employed to facilitate empirical testing of the effects of color, namely, the CIE chromaticity coordinates x and y or Munsell values, for both allow translation from one to the other.
