Objectives: Assessing subjective, patient-reported outcomes such as quality of life (QoL) is essential to health care research. This study aimed to assess the properties of a QoL measure relating to pain and discomfort: the WHOQOL-Pain. Method: Chronic low back pain patients (n=133) completed the WHOQOL-Pain, SF-12, and short-form McGill Pain Questionnaire before treatment started and again 2-4 weeks later. Of these, 76 received a lumbar epidural steroid injection, and 57 were waiting to receive treatment. Results: Overall, there was no significant difference in effect of either epidural injections or no treatment on bringing about an improvement to QoL overtime. Moderate effect sizes were found for 5 facets including pain relief and uncertainty. Small effect sizes were found for 7 facets including vulnerability, fear and worry, anger and frustration. Larger effect sizes were found for those reporting the most improvement in pain. The waiting group reported no significant changes to QoL but small changes for uncertainty. Three of the four new facets were sensitive to change and test-retest reliability (stability) was confirmed in three. Discussion: Although this study was not designed to test treatment effectiveness, the WHOQOL-Pain enables patients to report changes to important aspects of QoL during many diverse interventions for relieving pain

A number of studies have shown a range of symptoms resulting from exposure to natural disasters such as flooding. Among these consequences, individuals may experience symptoms of post-traumatic stress disorder (PTSD), depression and anxiety. The aim of this study was to examine the psychological impact of flooding in the UK. A cross-sectional survey was used to investigate the psychological symptoms associated with the aftermath of the flood amongst adults living in the affected communities. A questionnaire battery including the Harvard Trauma Questionnaire (trauma and symptoms associated with PTSD), Hopkins Symptom Checklist (anxiety and depression), Coping Strategies Questionnaire and a range of questions addressing sociodemographic characteristics and factors relating to the flood was administered to households in flood-affected areas. Four hundred and forty four completed questionnaires were returned. 27.9% of participants met criteria for symptoms associated with PTSD, 24.5% for anxiety and 35.1% for depression. Females had higher mean scores on PTSD, anxiety and depression than males. Most frequently reported coping strategies were rational, detached and avoidant, with the least frequent being emotional coping. Having to vacate home following flood, previous experience of flooding and poor health were associated with greater psychological distress. Detached coping appeared to be related to less distress. Although it is not possible to determine whether the symptoms were a direct consequence of the flood, symptoms of distress are a significant issue amongst communities affected by environmental events warranting further attention to prevent chronic distress.

INTRODUCTION: A range of human factors have been shown to impact on surgical performance although little is known about the impact of training on the views of surgeons towards these factors or how receptive surgeons are to such training. SUBJECTS AND METHODS: This was an observational pilot study using a short questionnaire designed to elicit views of surgeons towards a range of human factors prior to, and immediately following, a course designed to address human factors in surgical performance. Focus groups were also conducted before and immediately after the course to elicit views. RESULTS: Of all the human factors assessed, decision-making was rated on a visual analogue scale as having the biggest impact on performance both before and after the course. In general, views of human factors changed following the course, most notably an increase in the extent to which work stress, interpersonal difficulties and personality were believed to affect performance. Three themes emerged from the focus groups: (i) personal professional development; (ii) the relationship between trainer and trainee; and (iii) the changing perspective. CONCLUSIONS: Surgeons from a range of specialties are receptive to training on the impact of human factors on performance and this study has shown that views may change following a course designed to address this. Further training to address the theory–practice gap is warranted in addition to an evaluation of its effectiveness.

Chronic pain has a considerable impact on patient-reported outcomes such as quality of life (QoL). To assess QoL in people with chronic pain, a pain and discomfort module (PDM) was developed for use with the WHOQOL-100 and its psychometric properties assessed. Sixteen items covered four facets on pain relief; anger and frustration; vulnerability, fear and worry; and uncertainty. Chronic low back pain patients (n = 133) (age 56; pain duration 85 months; 65% female) completed the WHOQOL-100 and PDM, McGill Pain Questionnaire, and SF-12. The PDM showed good internal consistency reliability (α = .88) (alphas .66–.81). Except for anger, all facets associated most strongly with their ‘parent’ domain. Pain and poorer QoL were strongly associated, supporting construct validity. The SF-12 physical health component associated strongly with pain relief, and the mental health score with other facets, indicating good concurrent validity. Discriminant validity tests showed that PDM scores distinguished between ill and well patients, and between those reporting different health statuses. The PDM has fair to good psychometric properties indicating its value as a patient-reported outcome measure for clinical trials.

The most effective pharmacological treatments for depression inhibit the transporters that reuptake serotonin (Selective Serotonin Reuptake Inhibitors – SSRIs) and noradrenaline (Noradrenaline Reuptake Inhibitors – NaRIs) into the presynaptic terminal. There is evidence to suggest that noradrenaline and serotonin enhancing drugs work through separate mechanisms to produce their clinical antidepressant action. Although most of the current evidence suggests there is little difference in overall efficacy between SSRIs and NaRIs, there are patients who respond to one class of compounds and not another. This suggests that treatment response could be predicted by genetic and/or clinical characteristics. Firstly, this study aims to investigate the influence of a polymorphism (SLC6A4) in the 5HT transporter in altering response to SSRI medication. Secondly, the study will investigate whether those with more severe depression have a better response to NaRIs than SSRIs. The GenPod trial is a multi-centre randomised controlled trial. GPs referred patients aged between 18–74 years presenting with a new episode of depression, who did not have any medical contraindications to antidepressant medication and who had no history of psychosis or alcohol/substance abuse. Patients were interviewed to ascertain their suitability for the study. Eligible participants (with a primary diagnosis of depression according to ICD10 criteria and a Beck Depression Inventory (BDI) score > 14) were randomised to receive one of two antidepressant treatments, either the SSRI Citalopram or the NaRI Reboxetine, stratified according to severity. The final number randomised to the trial was 601. Follow-up assessments took place at 2, 6 and 12 weeks following randomisation. Primary outcome was measured at 6 weeks by the BDI. Outcomes will be analysed on an intention-to-treat basis and will use multiple regression models to compare treatments. The results of the trial will provide information about targeting antidepressant treatment for individual patients; in turn this may increase prescribing efficacy, thereby speeding recovery and reducing the cost to the NHS. It will also help to understand the different roles that noradrenaline and serotonin might play in the biology of depression. The trial is expected to report in the autumn of 2008. ISRCTN 31345163

This article reports the development of a pain and discomfort module (PDM) designed to assess the full impact of quality of life (QoL) relating to chronic pain, which could be used with the generic World Health Organisation Quality of Life Assessment (WHOQOL). First, cognitive interviewing was completed with nine participants with chronic pain, for 108 items representing 10 pain-specific facets of QoL. Sixty-eight QoL items and 16 importance questions on pain were relevant, comprehensive, comprehensible and acceptable to users, and were confirmed to assess their purported concepts. Secondly, these items were pilot tested using a cross-sectional survey of 216 people with chronic pain, to investigate the preliminary psychometric properties of the PDM, and reduce its items statistically. All new facets were important to those with chronic pain. Sixteen items within four facets of pain relief, anger and frustration, vulnerability/fear/worry, and uncertainty were retained, and demonstrated acceptable to good internal consistency reliability (α = 0.77–0.85). The PDM is a self-administered, multidimensional subjective assessment of pain-related QoL, with potential to evaluate pain-relieving interventions, identify sufferer's needs, and for survey use.

Objectives Whether individuals with chronic low back pain (CLBP) are willing to accept their pain, is of interest to pain management, but how far is the acceptance of pain related to a good quality of life (QoL)? Recently available measures now enable this question to be investigated; these are (1) the Chronic Pain Acceptance Questionnaire (CPAQ) and a revised version, here described as a short-form (SF-CPAQ), and (2) the World Health Organization Quality of Life Assessment (WHOQOL)-Pain, which is composed of the generic WHOQOL-100 profile (25 facets in 6 domains), and 4 additional facets within a specific pain and discomfort module (PDM). Method Eighty-six CLBP outpatients (62.8% female, mean age 54.3 y, mean pain duration 69.4 mo) completed the CPAQ and WHOQOL-Pain, mailed 2 weeks before a pain clinic appointment. Results General QoL was positively associated with overall acceptance of pain (CPAQ: r=0.376, P=0.003; SF-CPAQ: r=0.582, Pr=0.455, Pr=0.493, Pr=−0.349, P=0.002). Pain level was important in explaining QoL relating to the physical and social domains and pain-related facets assessed by the PDM. Overall, acceptance contributed to explain QoL in the level of independence and environment domains and for pain-related QoL assessed by the PDM. However, pain and acceptance only made a modest contribution to explaining psychologic and social dimensions of QoL. Discussion The results indicate that present pain level and whether or not pain is accepted play an important role in the QoL of patients with chronic pain. Additionally, the results provide construct validity for the WHOQOL-Pain and SF-CPAQ measures, especially dimensions of pain willingness and activities engagement. The findings have implications for the way health care is delivered, particularly for the role of acceptance-based treatments for individuals with CLBP.

Objective. To investigate the perceived barriers among GPs towards introducing participation in randomized controlled trials (RCTs) to patients presenting with depression during consultations. Methods. Qualitative study using semi-structured interviews. Interviews were recorded using a digital voice recorder, transcribed verbatim and analysed using the Framework Approach. The participants were 41 GPs from five primary care trusts in the South West who were collaborating with the University of Bristol on an RCT recruiting patients with depression. Results. Three themes were identified: (i) concern about protecting the vulnerable patient and the impact on the doctor–patient relationship; (ii) the perceived lack of skill and confidence of GPs to introduce a request for research participation within a potentially sensitive consultation; and (iii) the priority given to clinical and administrative issues over research participation. These themes were underpinned by GPs' observations that consultations with people about depression differed in content, style and perceived difficulty compared to other types of consultations. Conclusion. Depressed patients were often viewed as vulnerable and in need of protection and it was seen as difficult and intrusive to introduce research. Patients were not always given the choice to participate in research in the same way that they are encouraged to participate in treatment decision making. A lack of skills in introducing research could be addressed with training through the new Primary Care Research Network. A more radical change in clinician attitudes and policy may be needed in order to give research a higher priority within primary care.
