Development and initial validation of the determinants of physical activity questionnaire

Background: Physical activity interventions are more likely to be effective if they target causal determinants of behaviour change. Targeting requires accurate identification of specific theoretical determinants of physical activity. Two studies were undertaken to develop and validate the Determinants of Physical Activity Questionnaire. Methods In Study 1, 832 male and female university staff and students were recruited from 49 universities across the UK and completed the 66-item measure, which is based on the Theoretical Domains Framework. Confirmatory factor analysis was undertaken on a calibration sample to generate the model, which resulted in a loss of 31 items. A validation sample was used to cross-validate the model. 20 new items were added and Study 2 tested the revised model in a sample of 466 male and female university students together with a physical activity measure. Results: The final model consisted of 11 factors and 34 items, and CFA produced a reasonable fit χ2 (472) = 852.3, p < .001, CFI = .933, SRMR = .105, RMSEA = .042 (CI = .037-.046), as well as generally acceptable levels of discriminant validity, internal consistency, and test-retest reliability. Eight subscales significantly differentiated between high and low exercisers, indicating that those who exercise less report more barriers for physical activity. Conclusions: A theoretically underpinned measure of determinants of physical activity has been developed with reasonable reliability and validity. Further work is required to test the measure amongst a more representative sample. This study provides an innovative approach to identifying potential barriers to physical activity. This approach illustrates a method for moving from diagnosing implementation difficulties to designing and evaluating interventions

Tracking Evidence Use in the Policy Process Methodological Summary

This is the outline of a novel method for tracking evidence use in the policy process. The aim of this method is that it be practical for all institutions, both small and large, context relevant, easy to use, and efficient in time and labour resources. The method follows three simple stages: This method: provides statistical data on evidence source preferences; tracks use and defines characteristics of those evidence sources with highest preference score; focuses on the individual preferences of policy actors, aggregated across the policy system; provides classification criteria which can be adjusted to suit the context and concerns of each research impact assessment

Knowledge and capabilities for products/services development: the UK spin-off firms context

Purpose – This article explores and investigates the skills and capabilities required in developing products and services within UK university spin-offs (USOs) by considering the model of products/services development (Verona, 1999). Design/methodology approach – mixed methods of 20 in-depth interviews and questionnaire survey with 204 founders of USOs. Findings – The findings contribute in filling the literature gap by demonstrating key knowledge and capabilities required to develop products/services within the unique and non-commercial context, in which USOs are created by academics who do not necessarily have entrepreneurial or business experience. Originality/value – This research contributes to studies of product/service development by adapting and modifying elements within the existing theoretical model to be applicable to the specific firm and country context, such as USOs in the UK. Further, the study extends knowledge on the interplay between knowledge management and product development. The applications of the findings are that they can inform academic entrepreneurs on the capabilities significant in the development process. They can also act as indicators to Technology Transfer Office (TTOs) in what is needed for the provision of appropriate support and training to academic founders/entrepreneurs in order to foster and enhance other entrepreneurial activities

Conductance quantization and snake states in graphene magnetic waveguides

We consider electron waveguides (quantum wires) in graphene created by suitable inhomogeneous magnetic fields. The properties of uni-directional snake states are discussed. For a certain magnetic field profile, two spatially separated counter-propagating snake states are formed, leading to conductance quantization insensitive to backscattering by impurities or irregularities of the magnetic field.Comment: 5 pages, 4 figures, final version accepted as Rapid Comm. in PR

Role of affective attitudes and anticipated affective reactions in predicting health behaviors

Objective: Two measures of affect-affective attitude (AA) and anticipated affective reaction (AAR)- have frequently been used individually, but rarely simultaneously, in correlational studies predicting health behaviors. This research assessed their individual and combined impact in predicting intention and action for a range of health behaviors, controlling for theory of planned behavior (TPB) variables. Method: Self-reported intentions and performance of health behaviors were the main outcome measures. Design: Study 1 is a meta-analysis of published studies (k = 16) measuring the relevant variables. In Study 2, adults (N = 426) completed questionnaires assessing TPB variables, past behavior, AA, AAR, and subsequent behavior for a range of health behaviors. Results: Across both studies, AA and AAR were only moderately intercorrelated, although both had significant correlations with both intentions and behavior. AA was a significant predictor of intentions and behavior after controlling for TPB variables (Studies 1 and 2) plus past behavior (Study 2). In Study 1, AAR was a significant predictor of behavior, but not intentions, when controlling for TPB variables. In Study 2, AAR was a significant predictor of intentions when controlling for both TPB variables plus past behavior (Study 2), but was not a significant predictor of behavior when controlling for either of these variables. Several relationships were moderated by health-behavior category. Conclusions: Both AA and AAR are important predictors of health behaviors and can have independent effects on intentions and action. Studies manipulating both variables to test their independent and combined effects on behavior change are required

Written versus verbal consent: a qualitative study of stakeholder views of consent procedures used at the time of recruitment into a peripartum trial conducted in an emergency setting.

BACKGROUND: Obtaining prospective written consent from women to participate in trials when they are experiencing an obstetric emergency is challenging. Alternative consent pathways, such as gaining verbal consent at enrolment followed, later, by obtaining written consent, have been advocated by some clinicians and bioethicists but have received little empirical attention. We explored women's and staff views about the consent procedures used during the internal pilot of a trial (GOT-IT), where the protocol permitted staff to gain verbal consent at recruitment. METHODS: Interviews with staff (n = 27) and participating women (n = 22). Data were analysed thematically and interviews were cross-compared to identify differences and similarities in participants' views about the consent procedures used. RESULTS: Women and some staff highlighted benefits to obtaining verbal consent at trial enrolment, including expediting recruitment and reducing the burden on those left exhausted by their births. However, most staff with direct responsibility for taking consent expressed extreme reluctance to proceed with enrolment until they had obtained written consent, despite being comfortable using verbal procedures in their clinical practice. To account for this resistance, staff drew a strong distinction between research and clinical care and suggested that a higher level of consent was needed when recruiting into trials. In doing so, staff emphasised the need to engage women in reflexive decision-making and highlighted the role that completing the consent form could play in enabling and evidencing this process. While most staff cited their ethical responsibilities to women, they also voiced concerns that the absence of a signed consent form at recruitment could expose them to greater risk of litigation were an individual to experience a complication during the trial. Inexperience of recruiting into peripartum trials and limited availability of staff trained to take consent also reinforced preferences for obtaining written consent at recruitment. CONCLUSIONS: While alternative consent pathways have an important role to play in advancing emergency medicine research, and may be appreciated by potential recruits, they may give rise to unintended ethical and logistical challenges for staff. Staff would benefit from training and support to increase their confidence and willingness to recruit into trials using alternative consent pathways. TRIAL REGISTRATION: This qualitative research was undertaken as part of the GOT-IT Trial (trial registration number: ISCRTN 88609453 ). Date of registration 26/03/2014
