The validity and reliability of an instrument to assess nursing competencies in spiritual care

Aim. This study contributes to the development of a valid and reliable instrument, the spiritual care competence scale, as an instrument to assess nurses’ competencies in providing spiritual care. Background. Measuring these competencies and their development is important and the construction of a reliable and valid instrument is recommended in the literature. Design. Survey. Method. The participants were students from Bachelor‐level nursing schools in the Netherlands (n = 197) participating in a cross‐sectional study. The items in the instrument were hypothesised from a competency profile regarding spiritual care. Construct validity was evaluated by factor analysis and internal consistency was estimated with Cronbach’s alpha and the average inter‐item correlation. In addition, the test–retest reliability of the instrument was determined at a two‐week interval between baseline and follow‐up (n = 109). Results. The spiritual care competence scale comprises six spiritual‐care‐related nursing competencies. These domains were labelled:
1 assessment and implementation of spiritual care (Cronbach’s α 0·82)
2 professionalisation and improving the quality of spiritual care (Cronbach’s α 0·82)
3 personal support and patient counseling (Cronbach’s α 0·81)
4 referral to professionals (Cronbach’s α 0·79)
5 attitude towards the patient’s spirituality (Cronbach’s α 0·56)
6 communication (Cronbach’s α 0·71). These subscales showed good homogeneity with average inter‐item correlations >0·25 and a good test–retest reliability. Conclusion. This study conducted in a nursing‐student population demonstrated valid and reliable scales for measuring spiritual care competencies. The psychometric quality of the instrument proved satisfactory. This study does have some methodological limitations that should be taken into account in any further development of the spiritual care competence scale. Relevance to clinical practice. The spiritual care competence scale can be used to assess the areas in which nurses need to receive training in spiritual care and can be used to assess whether nurses have developed competencies in providing spiritual care.     

Posttraumatic stress disorder in first-time myocardial infarction patients

OBJECTIVES: The objectives of this study were to investigate the prevalence of posttraumatic stress disorder in patients with a first myocardial infarction compared with a random sample of healthy controls and to determine variables associated with the disorder. DESIGN: A questionnaire was distributed to 112 consecutive patients 4 to 6 weeks after infarction and to 115 healthy controls selected randomly from the general population. Objective clinical measures were obtained from the patients' medical records. RESULTS: Twenty-five (22%) patients qualified for a diagnosis of posttraumatic stress disorder (PTSD) compared with 8 (7%) controls with patients being more than a three-fold (OR: 3.84; 95% CI: 1.65 to 8.94) risk of having the disorder. When adjusting for other variables, the risk was reduced to above a two-fold risk (OR: 2.71; 95% CI: 0.99-7.41). In patients and controls, depression and neuroticism were associated with a diagnosis of PTSD adjusting for other variables. In patients, anxiety was associated with a diagnosis of PTSD adjusting for other variables. Left ventricular ejection fraction and symptoms of angina pectoris were not related to a diagnosis of PTSD in the patient group. CONCLUSIONS: Given that previous research has shown that persons with PTSD are at increased risk of cardiovascular diseases, cardiac patients with the disorder may be at a higher risk of recurrent cardiac events. Although longitudinal studies are needed to confirm such a relationship, this disorder should not be overlooked because of its potential role in reinfarctions and mortality.     

Maintenance of PtdIns45P2 pools under limiting inositol conditions,as assessed by liquid chromatography-tandem mass spectrometry and PtdIns45P2 mass evaluation in Ras-transformed cells

Inositol-containing molecules are involved in important cellular functions, including signalling, membrane transport and secretion. Our interest is in lysophosphatidylinositol and the glycerophosphoinositols, which modulate cell proliferation and G-protein-dependent activities such as adenylyl cyclase and phospholipase A₂. To investigate the role of glycerophosphoinositol (GroPIns) in the modulation of Ras-dependent pathways and its correlation to Ras transformation, we employed a novel liquid chromatography-tandem mass spectrometry technique to directly measure GroPIns in cell extracts. The cellular levels of GroPIns in selected parental and Ras-transformed cells, and in some carcinoma cells, ranged from 44 to 925 μM, with no consistent correlation to Ras transformation across all cell lines. Moreover, the derived cellular inositol concentrations revealed a wide range (150 μM to 100 mM) under standard [³H]-inositol-loading, suggesting a complex relationship between the inositol pool and the phosphoinositides and their derivatives. We have investigated these pools under specific loading conditions, designing a further HPLC analysis for GroPIns, combined with mass determinations of cellular phosphatidylinositol 4,5-bisphosphate. The data demonstrate that limiting inositol conditions identify a preferred pathway of inositol incorporation and retention into the polyphosphoinositides pool. Thus, under conditions of increased metabolic activity, such as receptor stimulation or cellular transformation, the polyphosphoinositide levels will be maintained at the expense of phosphatidylinositol and the turnover of its aqueous derivatives.     

The role of personality variables and social support in distress and perceived health in patients following myocardial infarction

Objectives: (1) To investigate whether patients with low versus high social support and satisfaction with support report less distress and health complaints following a first myocardial infarction (MI). (2) To examine whether personality traits mediate social support and its effect on distress and health complaints. Methods: A questionnaire was distributed to 112 consecutive patients with a first MI 4–6 weeks postinfarction. Objective clinical measures were obtained from the patients' medical records. Results: Patients with low social support were at increased risk of depression and posttraumatic stress disorder (PTSD). Patients less satisfied with support were at increased risk of anxiety, depression, PTSD, and reported more health complaints. Generally, larger effect sizes were found for satisfaction with support compared with social support per se in relation to distress and health complaints. Neuroticism was identified as an independent predictor of all types of distress and health complaints when including both traits and social support variables in multivariable analyses, adjusted for demographic and clinical variables. Satisfaction with support only remained an independent predictor of depression. Conclusion: These results suggest that personality traits may mediate social support and its effect on distress and health complaints. Hence, it may be important to include personality variables when investigating social support in relation to distress and health. In clinical practice, screening for particular personality traits could identify patients at risk of distress and recurrent cardiac events.     

Neurofeedback improves executive functioning in children with autism spectrum disorders

Seven autistic children diagnosed with autism spectrum disorders (ASD) received a neurofeedback treatment that aimed to improve their level of executive control. Neurofeedback successfully reduced children's heightened theta/beta ratio by inhibiting theta activation and enhancing beta activation over sessions. Following treatment, children's executive capacities were found to have improved greatly relative to pre-treatment assessment on a range of executive function tasks. Additional improvements were found in children's social, communicative and typical behavior, relative to a waiting list control group. These findings suggest a basic executive function impairment in ASD that can be alleviated through specific neurofeedback treatment. Possible neural mechanisms that may underlie neurofeedback mediated improvement in executive functioning in autistic children are discussed.     

Socioeconomic inequalities in quality of life and psychological outcomes among cardiac patients

Objectives:  The aim of this article is to explore socioeconomic inequalities in the psychological characteristics (psychological well-being, perceived mental health status) and perceived quality of life among cardiac patients. Methods:  A structured interview was conducted with 362 patients (32% women, mean age 56 ± 7.3 years) referred for coronary angiography. The GHQ-28 was used to measure psychological well-being, the SF-36 for perceived mental health status. Income and education indicated socioeconomic position. Logistic regressions were employed, adjusted for age, gender, functional status and severity of disease. Results:  Patients with low income or education had a higher probability of having poor psychological well-being compared to participants with high income or education (OR 5.5,CI 2.32-12.80; OR 3.1,CI 1.52-6.37 resp.), and were also more likely to have worse mental health status (OR2.9,CI 1.02-8.51;OR 4.8,CI 1.36-16.99 resp.), and low quality of life (OR 2.9,CI 1.02-8.51; OR 4.8,CI 1.36-16.99 resp.). Conclusions:  Socioeconomic status was found to be negatively associated with the psychological outcomes and quality of life among cardiac patients. Socioeconomic inequalities should be taken into account when designing suitably-adapted interventions focusing on psychosocial factors among cardiac patients.

Neuroticism and extraversion in association with quality of life in patients with Parkinson’s disease

Purpose  Personality traits appear as determinants of quality of life (QoL) in most chronic diseases. The aim of this study is to explore whether neuroticism and extraversion contribute to the variance in QoL in patients with Parkinson’s disease (PD) when controlled for age, functional status and disease duration. Methods  The Parkinson’s Disease Quality of Life Questionnaire (PDQ-39) was used to assess QoL and the Unified Parkinson’s Disease Rating Scale (UPDRS) for disease severity. Neuroticism and extraversion were measured with the Eysenck Personality Questionnaire (EPQR-A). Multiple linear regression analysis was then used to assess the contribution of neuroticism and extraversion to QoL. Results  The sample consisted of 153 PD patients (48.4% women; 67.9 ± 9.3 years; mean disease duration 7.5 ± 5.8 years). Neuroticism was, after disease severity, the second most important variable associated with QoL in PD patients, in particular for domains associated with psychological processes: emotional well-being, social support, stigma and communication. A higher score in extraversion was significantly associated with better emotional well-being in males, but surprisingly, with worse emotional well-being in females. Conclusions  After functional status, personality traits were clearly associated with QoL in PD patients. Therefore, they should be taken into account by health-care professionals in their appraisal of patient complaints.     

Vaccine-elicited Human T Cells Recognizing Conserved Protein Regions Inhibit HIV-1

Virus diversity and escape from immune responses are the biggest challenges to the development of an effective vaccine against HIV-1. We hypothesized that T-cell vaccines targeting the most conserved regions of the HIV-1 proteome, which are common to most variants and bear fitness costs when mutated, will generate effectors that efficiently recognize and kill virus-infected cells early enough after transmission to potentially impact on HIV-1 replication and will do so more efficiently than whole protein-based T-cell vaccines. Here, we describe the first-ever administration of conserved immunogen vaccines vectored using prime-boost regimens of DNA, simian adenovirus and modified vaccinia virus Ankara to uninfected UK volunteers. The vaccine induced high levels of effector T cells that recognized virus-infected autologous CD4⁺ cells and inhibited HIV-1 replication by up to 5.79 log₁₀. The virus inhibition was mediated by both Gag- and Pol- specific effector CD8⁺ T cells targeting epitopes that are typically subdominant in natural infection. These results provide proof of concept for using a vaccine to target T cells at conserved epitopes, showing that these T cells can control HIV-1 replication in vitro.
