The question-behaviour effect in risk behaviours

The question-behaviour effect (QBE) refers to the finding that asking individuals questions about their cognitions and/or behaviour or to predict future behaviour, can influence subsequent behaviour performance. Health risk behaviours are those behaviours that should be discouraged to produce favourable health outcomes such as smoking, excessive alcohol use and unhealthy eating. The current thesis aimed to investigate the influence of the QBE over health risk behaviours. It provides an original contribution to the literature in its focus on the QBE in these types of health behaviour. A comprehensive systematic review of the QBE literature demonstrated a small, significant effect of the QBE in general, however only 16 previous studies had been conducted investigating health risk behaviours and the majority of these focused on assessing behaviour at baseline. These previous studies produced a non-significant reduction in health risk behaviours as a result of the QBE. The systematic review identified a number of moderators of the QBE including setting. Seven empirical studies are presented here, conducted in a range of settings (field, online, and lab). The data presented show mixed evidence of the QBE for risk behaviours. A mini meta-analysis of the studies presented demonstrated an overall small and non-significant effect of the QBE on risk behaviours. The individual studies demonstrated that the QBE has the potential to increase and reduce these behaviours. Three lab studies demonstrated an increase in unhealthy snacking as a result of questioning intentions relating to behaviour. This was also supported in one of the online studies, where smoking tended to be greater in individuals questioned on this behaviour compared to control, although the difference in conditions was not significant in all measures of behaviour. However one online study demonstrated a significant reduction in multiple health behaviours (risk and protection), when the QBE was combined with a dissonance manipulation. The QBE has the potential to have a small influence over health risk behaviours and the studies presented here demonstrate that asking about these behaviours has the potential to increase them. The QBE may need to be combined with further manipulation focusing on motivation or dissonance to reduce these behaviours consistently

Parental age influences offspring telomere loss

1. The age of the parents at the time of offspring production can influence offspring longevity, but the underlying mechanisms remain poorly understood. The effect of parental age on offspring telomere dynamics (length and loss rate) is one mechanism that could be important in this context. 2. Parental age might influence the telomere length that offspring inherit or age-related differences in the quality of parental care could influence the rate of offspring telomere loss. However, these routes have generally not been disentangled. 3. Here, we investigated whether parental age was related to offspring telomere dynamics using parents ranging in age from 2 to 22 years old in a free-living population of a long-lived seabird, the European shag (Phalacrocorax aristotelis). By measuring the telomere length of offspring at hatching and towards the end of the post-natal growth period, we could assess whether any potential parental age effect was confined to the post-natal rearing period. 4. There was no effect of maternal or paternal age on the initial telomere length of their chicks. However, chicks produced by older mothers and fathers experienced significantly greater telomere loss during the post-natal nestling growth period. We had relatively few nests in which the ages of both parents were known, and individuals in this population mate assortatively with respect to age. Thus, we could not conclusively determine whether the parental age effect was due to maternal age, paternal age, or both; however, it appears that the effect is stronger in mothers. 5. These results demonstrate that in this species, there was no evidence that parental age was related to offspring hatching telomere length. However, telomere loss during nestling growth was reduced in the offspring of older parents. This could be due to an age-related deterioration in the quality of the environment that parents provide, or because parents that invest less in offspring rearing live to an older age

Rethinking Preventing Homelessness amongst Prison Leavers

The Wales (Housing) Act 2015 introduced a preventative approach to addressing homelessness that impacted on prison leavers in Wales. Since the same changes will take effect in England from October 2018, this paper provides early insight into how new preventative duties have been implemented in Wales. Drawing on interviews with 114 stakeholders and 75 prison leavers, we report that the promise associated with a preventative agenda is presently not fully realised. We contend that resettlement activity might be improved if it was better incentivised and facilitated inside the prison wall. However, we also suggest the time has come for more radical options to be pursued to address homelessness amongst prison leavers. We argue against short prison sentences, which are so often causative of homelessness, and for providers of probation services to be better incentivised and resourced to take a more active role in meeting accommodation needs

Preventing homelessness among women prison leavers in Wales

Under the Housing (Wales) Act 2014, prison leavers are among those who are no longer considered a priority need. This paper draws on interviews conducted with 17 women prison leavers and ten professionals that formed part of a Welsh Government funded evaluation of homelessness services to adults in the secure estate. The findings in this study lend support to previous research that indicates women who come into contact with the criminal justice system often have multiple and complex needs. The need for gender specific services and more availability of supported accommodation to ensure the effective resettlement of women prison leavers is also identified

The question-behaviour effect: a theoretical and methodological review and meta-analysis

Research has demonstrated that asking people questions about a behaviour can lead to behaviour change. Despite many, varied studies in different domains, it is only recently that this phenomenon has been studied under the umbrella term of the question-behaviour effect (QBE) and moderators of the effect have been investigated. With a particular focus on our own contributions, this article: (1) provides an overview of QBE research; (2) reviews and offers new evidence concerning three theoretical accounts of the QBE (behavioural simulation and processing fluency; attitude accessibility; cognitive dissonance); (3) reports a new meta-analysis of QBE studies (k = 66, reporting 94 tests) focusing on methodological moderators. The findings of this meta-analysis support a small significant effect of the QBE (g = 0.14, 95% CI = 0.11, 0.18, p < .001) with smaller effect sizes observed in more carefully controlled studies that exhibit less risk of bias and (4) also considers directions for future research on the QBE, especially studies that use designs with low risk of bias and consider desirable and undesirable behaviour separately

A workplace Acceptance and Commitment Therapy (ACT) intervention for improving healthcare staff psychological distress : a randomised controlled trial

The levels of psychological distress and burnout among healthcare staff are high, with negative implications for patient care. A growing body of evidence indicates that workplace programmes based on Acceptance and Commitment Therapy (ACT) are effective for improving employees’ general psychological health. However, there is a paucity of research examining the specific psychological and/or behavioural processes through which workplace ACT programmes transmit their beneficial effects. The aim of this randomised controlled trial was to investigate the outcomes and putative processes of change in a 4-session ACT training programme designed to reduce psychological distress among healthcare staff (n = 98). Ninety-eight employees of a healthcare organisation were randomly allocated to the ACT intervention or to a waiting list control group. Study measures were administered on four occasions (baseline, mid-intervention, post-intervention, and follow-up) over a three-month evaluation period. Results showed that the ACT intervention led to a significant decrease in symptoms of psychological distress and a less pronounced reduction in burnout. These effects were mediated primarily via an improvement in mindfulness skills and values-based behaviour and moderated by participants’ initial levels of distress. At four-week post-intervention, 48% of participants who received the ACT intervention showed reliable improvements in psychological distress, with just under half of the aforementioned improvements (46.15%) meeting criteria for clinically significant change. The results advance ACT as an effective stress management intervention for healthcare staff. The findings should be confirmed in a large scale randomised controlled trial with longer follow-up and cost-effectiveness analyses

Imaginary homelessness prevention with prison leavers in Wales

Despite a move towards more preventative practices, we have reported that policy objectives to help prison leavers find accommodation on release in Wales have not translated into improved outcomes for this group. In this article we engage in a critical examination of why this might be and how local authority Housing Solutions staff in Wales, newly placed centre stage in the process, go about preventing homelessness amongst prison leavers. Drawing on Carlen’s concept of ‘imaginary penalities’, we suggest that practice with this group is performed only ritualistically. Drawing on Ugelvik’s notion of ‘legitimation work’ we suggest this state of affairs is legitimised by focusing on prison leavers’ responsibility for their homelessness over their rights to housing, and public protection over promoting resettlement. In response we advocate for less-punitive justice and housing policies, underpinned by the right to permanent housing for all and wherein stable accommodation is understood as the starting point for resettlement for prison leavers. The analysis presented in this article provides insights to how homelessness policies could play out in jurisdictions where more joint working between housing and criminal justice agencies are being pursued and/or preventative approaches to managing homelessness are being considered

In Vivo Water Dynamics in Shewanella oneidensis Bacteria at High Pressure

Abstract: Following observations of survival of microbes and other life forms in deep subsurface environments it is necessary to understand their biological functioning under high pressure conditions. Key aspects of biochemical reactions and transport processes within cells are determined by the intracellular water dynamics. We studied water diffusion and rotational relaxation in live Shewanella oneidensis bacteria at pressures up to 500 MPa using quasi-elastic neutron scattering (QENS). The intracellular diffusion exhibits a significantly greater slowdown (by −10–30%) and an increase in rotational relaxation times (+10–40%) compared with water dynamics in the aqueous solutions used to resuspend the bacterial samples. Those results indicate both a pressure-induced viscosity increase and slowdown in ionic/macromolecular transport properties within the cells affecting the rates of metabolic and other biological processes. Our new data support emerging models for intracellular organisation with nanoscale water channels threading between macromolecular regions within a dynamically organized structure rather than a homogenous gel-like cytoplasm

Decision regret in men living with and beyond nonmetastatic prostate cancer in the United Kingdom: A population‐based patient‐reported outcome study

Objective: Clinical options for managing nonmetastatic prostate cancer (PCa) vary. Each option has side effects associated with it, leading to difficulty in decision‐making. This study aimed to assess the relationship between patient involvement in treatment decision‐making and subsequent decision regret (DR), and quantify the impact of health‐related quality of life (HRQL) outcomes on DR. Methods: Men living in the United Kingdom, 18 to 42 months after diagnosis of PCa, were identified from cancer registration data and sent a questionnaire. Measures included the Decision Regret Scale (DRS), Expanded Prostate cancer Index Composite short form (EPIC‐26), EQ‐5D‐5L, and an item on involvement in treatment decision‐making. Multivariable ordinal regression was utilized, with DR categorized as none, mild, or moderate/severe regret. Results: A total of 17 193 men with stage I‐III PCa completed the DRS: 36.6% reported no regret, 43.3% mild regret, and 20.0% moderate/severe regret. The odds of reporting DR were greater if men indicated their views were not taken into account odds ratio ([OR] = 6.42, 95% CI: 5.39‐7.64) or were involved “to some extent” in decision‐making (OR = 4.63, 95% CI: 4.27‐5.02), compared with men who were “definitely” involved. After adjustment, including for involvement, men reporting moderate/big problems with urinary, bowel, or sexual function were more likely to experience regret compared with men with no/small problems. Better HRQL scores were associated with lower levels of DR. Conclusions: This large‐scale study demonstrates the benefit of patient involvement in treatment decision‐making for nonmetastatic PCa. However, men experiencing side effects and poorer HRQL report greater DR. Promoting engagement in clinical decision‐making represents good practice and may reduce the risk of subsequent regret
