Validating the Philadelphia Mindfulness Scale [PMS] for Those with Fibromyalgia
Objectives: Dispositional mindfulness [DM] has become an important construct in understanding and treating fibromyalgia. However, few DM measures exist that have been validated in those with fibromyalgia. The Philadelphia Mindfulness Scale [PMS] is a self-report of DM. In the current study, we validate the PMS within a sample of individuals with fibromyalgia. Design: This was a cross-sectional online study. This enabled the recruitment of a larger sample of individuals with experiences of fibromyalgia than may have been achieved through face-to-face assessment. A cross-sectional approach was adopted to minimise resource demands. Method: The PMS alongside measures of fibromyalgia severity [The Revised Fibromyalgia Impact Questionnaire], affect [Positive and Negative Affect Scale] and decentring [Experiences Questionnaire] were completed online by a sample of N=936 individuals with fibromyalgia. Results: Confirmatory factor analysis supported a revised three-factor structure for the PMS. This factor structure excluded items which could overlap with hypervigilance within fibromyalgia. The three supported factors were Awareness, Non-judging/Control and Non-suppression/reactivity. Concurrent validity of the subscales was partially supported via correlations with positive affect [PA] and negative affect [NA] and decentring. Conclusions: The results support the use of the PMS in individuals with fibromyalgia, and in particular the use of this measure to compare those with and without experience of meditation. The PMS may be a useful tool in evaluating mindfulness-based interventions [MBIs] within this population. Limitations: The online design prevented more in-depth assessment of fibromyalgia. As the study was cross-sectional, test re-test reliability could not be assessed
Goal fluency, pessimism and disengagement in depression
This is the final version. Available on open access from Public Library of Science via the DOI in this record.The author accepted manuscript version is also in ORE at http://hdl.handle.net/10871/24574Data Availability: All relevant data are within the paper and its Supporting Information file.Despite the development of prominent theoretical models of goal motivation and its importance in daily life, research has rarely examined goal dysregulation processes in clinical depression. Here we aimed to investigate problematic aspects of goal regulation in clinically depressed adults, relative to controls. Depressed participants (n = 42) were recruited from two Improving Access to Psychological Therapy clinics in north-west England. Control participants (n = 51) were recruited from the same region. Participants generated personal approach goals (e.g., improve my marathon time) and avoidance goals (e.g., avoid getting upset over little things) and completed self-report measures of goal attainment likelihood and depressive symptoms. Participants also completed a measure of ease of disengagement from unattainable goals and re-engagement with new goals. Compared to controls, depressed participants reported fewer approach goals (but not more avoidance goals), rated their approach goal (rewarding) outcomes as less likely to happen and avoidance goal (threatening) outcomes as more likely to happen. Depressed participants also reported greater ease of disengagement from unattainable goals and more difficulty re-engaging with new goals than controls. Our findings extend current knowledge of the psychopathology of depression from a goal regulation perspective, suggesting that pessimism around goal pursuit accompanies fewer approach goal pursuits and a general tendency to disengage when difficulties are encountered.University of Liverpoo
The structure of haemoglobin bound to the haemoglobin receptor IsdH from Staphylococcus aureus shows disruption of the native α-globin haem pocket
© 2015 International Union of Crystallography. Staphylococcus aureus is a common and serious cause of infection in humans. The bacterium expresses a cell-surface receptor that binds to, and strips haem from, human haemoglobin (Hb). The binding interface has previously been identified; however, the structural changes that promote haem release from haemoglobin were unknown. Here, the structure of the receptor-Hb complex is reported at 2.6 Å resolution, which reveals a conformational change in the α-globin F helix that disrupts the haem-pocket structure and alters the Hb quaternary interactions. These features suggest potential mechanisms by which the S. aureus Hb receptor induces haem release from Hb
A Qualitative Analysis of Problematic and Non-problematic Alcohol Use After Bariatric Surgery
Objectives
Bariatric surgery is an effective weight loss tool, but an under-communicated side effect may include the increased risk for alcohol problems. Few studies have examined contributors towards alcohol problems following surgery using a qualitative approach. Therefore, the current study aimed to generate insight informed by participants with problematic alcohol use following bariatric surgery, in comparison with participants without.
Methods
Participants (14; females, n = 9; males, n = 5) completed semi-structured interviews using questions relating to alcohol use, relationship to food, support and surgical experiences. Thematic analysis was conducted to provide insight into the factors which influenced drinking behaviours that participants engaged in following bariatric surgery, and motivations for drinking or limiting alcohol.
Results
Five core themes were identified between both participants with and without problematic alcohol use: (1) drinking motivations, (2) self-image, (3) impact of restriction on eating behaviour, (4) support needs and (5) surgical preparedness. A sixth core theme (“resilience”) was identified specifically amongst participants without problematic alcohol use. Divergent experiences, cognitions and behaviours formed sub-themes within the five core themes and highlighted the differences between participants with and without problematic alcohol use within the core themes.
Conclusion
This study is the first to qualitatively assess themes relating to the development of problematic alcohol use after bariatric surgery while additionally using a comparison group without problematic alcohol use. The findings highlight key features which contribute to problematic alcohol use, as well as experiences and cognitions that may be helpful in preventing this phenomenon in bariatric populations
Rumination selectively mediates the association between actual-ideal (but not actual-ought) self-discrepancy and anxious and depressive symptoms
This is the author accepted manuscript. The final version is available from Elsevier via the DOI in this record.Actual-ideal and actual-ought self-discrepancies have been theorised to be independently
associated with depressive and anxious symptoms respectively. This study tested this
prediction and extended it to consider whether rumination mediates these relationships. One
hundred and thirty-eight students (48 males, 90 females) listed four adjectives describing how
they would ideally hope to be and four adjectives describing how they ought to be.
Participants then rated how distant they perceived themselves to be from each of their ideal
and ought selves, as well as the importance of each ideal and ought self. Finally, participants
self-reported levels of negative rumination, anxious and depressive symptoms. Actual-ideal
self-discrepancy was independently associated with both anxious and depressive symptoms,
whereas actual-ought self-discrepancy was independently associated with anxious symptoms
only. Rumination mediated the independent relationships between actual-ideal selfdiscrepancy and anxious and depressive symptoms. Actual-ought self-discrepancy retained an
independent association with anxious symptoms that was not mediated through rumination.
Anxious and depressive symptoms both have independent associations with actual-ideal selfdiscrepancies, whereas anxious symptoms are uniquely associated with actual-ought selfdiscrepancies. We reveal further evidence for rumination as a cognitive-motivational
transdiagnostic process linking self-regulatory difficulties with anxious and depressive
symptoms

Self-regulatory goal motivational processes in sustained New Year resolution pursuit and mental wellbeing
This is the final version. Available on open access from MDPI via the DOI in this recordData Availability Statement:
Anonymous data was collected and saved on an SPSS datafile. This SPSS dataset is deposited at Edith Cowan University’s data repository: https://ro.ecu.edu.au/datasets/57/Recent research suggests people typically “give up” pursuing their New Year resolutions within the first month. The present study investigated goal features proposed to be implicated in promoting both mental wellbeing and sustained New Year resolution pursuit. Australian and UK participants (n = 182) took part in an online longitudinal study, including four timepoints over a two-month period. At baseline, participants listed the New Year resolution to which they were most committed, and completed self-report measures to assess mental wellbeing, goal flexibility and tenacity. At the follow-up surveys, participants completed the wellbeing measure and their New Year resolution commitment, effort and stickability. As predicted, flexibility predicted wellbeing across time, however, tenacity did not. Counter to prediction, neither flexibility nor tenacity reported at baseline predicted “sticking” with one’s New Year resolution. The predicted interaction between flexibility and tenacity was not significant. New Year resolutions focused predominantly on “diet” and “exercise” were predominantly the same resolutions previously pursued and tended to be relatively abstract. Although goal flexibility predicted greater wellbeing, the findings overall tend to support the view that people are not particularly good at sticking with their New Year resolutions. Implications of the findings are discussed
Women’s Experiences of Vulvodynia: An Interpretative Phenomenological Analysis of the Journey Toward Diagnosis
Vulvodynia is the experience of idiopathic pain characterized by burning, soreness, or throbbing in the external female genitalia or vulva and is estimated to be experienced by 4–16% of the female population, yet only half of women seek help regarding their symptoms. Of the women who do seek help, only around 2% obtain a diagnosis. Therefore, the aim of the current study was to explore the experiences of women with vulvodynia on their journey toward diagnosis, by using semi-structured interviews and an interpretative phenomenological analysis (IPA) methodology. Eight women were interviewed, and their experiences were analyzed and interpreted into three master themes, each with constituent sub-themes: (1) The Journey Is a Battle, (2) “What Is Vulvodynia?”: Ambivalence Toward Diagnosis, and (3) Patriarchy, Women, and Sex. Overall, women perceived a healthcare system which was dismissive and shaming, with an inadequate knowledge of vulvodynia. This in turn impacted on women’s psychological well-being. Psychological understanding, one-to-one therapy, and consultation and training for healthcare professionals may help to improve the psychological well-being of women with vulvodynia
Diagnosing Dementia in the Clinical Setting: Can Amyloid PET Provide Additional Value Over Cerebrospinal Fluid?
Cerebrospinal fluid (CSF) measures of amyloid and tau are the first-line Alzheimer's disease biomarkers in many clinical centers. We assessed if and when the addition of amyloid PET following CSF measurements provides added diagnostic value. Twenty patients from a cognitive clinic, who had undergone detailed assessment including CSF measures, went on to have amyloid PET. The treating neurologist's working diagnosis, and degree of diagnostic certainty, was assessed both before and after the PET. Amyloid PET changed the diagnosis in 7/20 cases. Amyloid PET can provide added diagnostic value, particularly in young-onset, atypical dementias, where CSF results are borderline and diagnostic uncertainty remains
