Effectiveness of a tailored communication intervention to improve physical activity in hypertensive patients: a twelve-month randomized controlled trial.

BACKGROUND: Cardiovascular diseases (CVDs) are a leading cause of morbidity and mortality globally. Arterial hypertension is one of the main cardiovascular risk factors. Despite this, individuals with hypertension often fail to follow medical advice to counteract cardiovascular risks. A physically active lifestyle is one of the most challenging behaviors to adopt. This study aimed to preliminarily investigate the effectiveness of a tailored print message intervention to increase physical activity in patients with arterial hypertension. METHODS: A sample of 188 patients with hypertension (mean age = 63 years; SD = 10.9; 50% men) participated in a theory-based tailored health communication intervention. Participants were randomly assigned to three parallel groups: (1) the tailored group, which received tailored health brochures; (2) the non-tailored group, which received non-tailored health brochures; or (3) the usual care group, which received no informative print materials. The longitudinal physical activity trajectories (baseline, 6- and 12-month follow-ups) were examined using repeated measures ANOVA and growth curve models. RESULTS: At the baseline, 38.8% of patients achieved the target physical activity. This percentage rose to 43.0% at 6-month follow-up and 46.0% at 12-month follow-up. The descriptive statistics divided in function of the experimental group suggested differences in the longitudinal trend of the mean physical activity depending on the experimental group. However, statistical significance using repeated measures ANOVA did not support this observation. The analysis of the growth curves suggested that the tailored group showed a progressive increase in physical activity over twelve months (the model that best described the longitudinal trajectory was a linear growth model). The non-tailored group showed an increase in physical activity six months after the beginning of the intervention, followed by a decrease (free time score model). The usual care group did not change over time (no-growth model). CONCLUSIONS: Findings suggest the effectiveness of the tailored intervention proposed. However, further investigations and empirical confirmations are required. TRIAL REGISTRATION: ISRCTN13415993 ( https://doi.org/10.1186/ISRCTN13415993 ). Registration date: 08/04/2019.

Quality of life changes over time and predictors in a large head and neck patients' cohort: secondary analysis from an Italian multi-center longitudinal, prospective, observational study-a study of the Italian Association of Radiotherapy and Clinical Oncology (AIRO) head and neck working group.

PURPOSE: The present study examined the longitudinal trajectories, through hierarchical modeling, of quality of life among patients with head and neck cancer, specifically symptoms burden, during radiotherapy, and in the follow-up period (1, 3, 6, and 12 months after completion of radiotherapy), through the M.D. Anderson Symptom Inventory Head and Neck questionnaire, formed by three factors. Furthermore, analyses were conducted controlling for socio-demographic as well as clinical characteristics. METHODS: Multi-level mixed-effects linear regression was used to estimate the association between quality of life and time, age, gender, household, educational level, employment status, ECOG performance status, human papilloma virus (HPV) status, surgery, chemotherapy, alcohol intake, and smoking. RESULTS: Among the 166 participants, time resulted to be a predictor of all the three questionnaire factors, namely, general and specific related symptoms and interference with daily life. Moreover, regarding symptom interference with daily activities factor, HPV-positive status played a significant role. Considering only HPV-negative patients, only time predicted patients' quality of life. Differently, among HPV-positive patients, other variables, such as gender, educational level, alcohol use, surgery, age at diagnosis, employment status, and ECOG status, resulted significant. CONCLUSION: It was evident that quality of life of patients with head and neck cancer declined during RT, whereas it slowly improved after ending treatment. Our results clarified the role of some socio-demographic and clinical variables, for instance, HPV, which would allow to develop treatments tailored to each patient.

The self and our perception of its synchrony - Beyond internal and external cognition.

The self is the core of our mental life which connects one's inner mental life with the external perception. Since synchrony is a key feature of the biological world and its various species, what role does it play for humans? We conducted a large-scale psychological study (n = 1072) combining newly developed visual analogue scales (VAS) for the perception of synchrony and internal and external cognition complemented by several psychological questionnaires. Overall, our findings showed close connection of the perception of synchrony of the self with both internal (i.e., body and cognition) and external (i.e., others, environment/nature) synchrony being associated positively with adaptive and negatively with maladaptive traits of self. Moreover, we have demonstrated how external (i.e., life events like the COVID-19 pandemic) variables modulate the perception of the self's internal-external synchrony. These findings suggest how synchrony with self plays a central role during times of uncertainty.

Attachment anxiety, reflective functioning and well-being as predictors of burn-out and psychological distress among psychotherapists: A longitudinal study.

OBJECTIVE: This study aims to longitudinally investigate the effects of individual's factors on subsequent burn-out/psychological distress in a sample of mental health practitioners, testing if higher attachment anxiety and avoidance and lower reflective functioning (i.e., certainty and uncertainty of mental states) and well-being at baseline may lead to a greater psychological distress and burn-out 1 year later. METHODS: The sample consisted of 40 experienced psychotherapists (females: 72.5%; mean age: 47.40 ± 9.48 years) who completed a battery of questionnaires at baseline and 1 year later. Statistical analyses were conducted with Bayesian multiple linear regressions. RESULTS: Greater attachment anxiety and certainty about mental states and lower individual's well-being at baseline predicted greater burn-out 1 year later. Similarly, greater attachment anxiety and lower individual's well-being at baseline predicted psychological distress at 1 year follow-up. Of note, uncertainty of mental states and avoidant attachment were not associated with outcomes. CONCLUSION: These findings suggest that the levels of burn-out and psychological distress among psychotherapists may be alleviated with interventions targeting attachment insecurity, specific aspects of reflective functioning (i.e., certainty about mental states) and well-being.

Impulsivity assessed ten years earlier and sociodemographic factors predict adherence to COVID-19 related behavioral restrictions in old individuals with hypertension.

BACKGROUND: The COVID-19 pandemic has had clear and dramatic repercussions on health, the economy, and psychosocial well-being. Behavioral measures, such as wearing facemasks and maintaining distance from others, have proven crucial in fighting the contagion's spread. This study aimed to investigate Type A personality traits and sociodemographic predictors of adherence to governmental measures in a sample of frail individuals. METHODS: A sample of 105 Italians over age 60 (Mean age = 70 years; 60.6% male) affected by hypertension who participated in a previous longitudinal study were assessed through a telephone structured interview. Sociodemographic information and Type A personality traits were retrieved from the original longitudinal study. Adherence behaviors were investigated through several questions regarding the compliance with home confinement, the use of facemasks and the observance of social distancing. Repeated measures Analyses of Variance (RMANOVA), Reliable Change Index, and binomial logistic regression analysis were performed. RESULTS: Only 33.3% of the participants reported adherence to all the governmental COVID-19 measures. Being a woman (OR = 4.84; 95% CI = 1.58, 14.90; p < 0.01), being retired (OR = 4.89; 95% CI = 1.09, 21.86; p < 0.05), and suffering from hypertension for a relatively short time (OR = 4.20; 95% CI = 1.22, 14.44; p < 0.05) positively predicted adherence to the governmental measures. Impulsivity resulted in a stable personality characteristic over the last ten years (p = 0.30). Having high levels of impulsivity (OR = 2.28; 95% CI = 1.13, 4.59; p < 0.05) negatively predicted adherence. CONCLUSIONS: Our results demonstrate that impulsivity is a stable personality facet that can have a robust negative impact on adherence behaviors to health claims. Overall, results show the importance to tailor communication strategies that consider the role of sociodemographic indicators and impulsivity to achieve a high level of adherence.

COVID-19: what about pregnant women during first lockdown in Italy?

OBJECTIVE: Lombardy was the most affected Italian region by COVID-19. To limit the spread of infection, the government issued a national social lockdown. The obstetrical-gynaecological emergencies and essential services were guaranteed to protect pregnant women's health, and a return to a medicalised childbirth was necessary. This situation could had amplified risk factors on the psychological wellbeing of mothers-to-be. Indeed, the last trimester of pregnancy is a period of increased vulnerability itself. METHOD: For better support women who experience pregnancy during social lockdown, we explored the impact of COVID-19 on psychic wellbeing of two samples of pregnant women (40 living in Lombardy and 35 in Tuscany). RESULTS: T-test and correlations analyses revealed that women living in the Lombardy had a higher perception of the centrality of COVID-19. Further, women that considered the pandemic as a significant event, experienced a higher perinatal depressive symptom. Those symptoms also arose in women who presented a higher number of intrusion and hyperarousal symptoms and a lower ability to plan. CONCLUSION: Pregnant women should be closely monitored and supported, especially those who live in high-risk areas, such as Lombardy Region. The target intervention could be focused on improving resilience to reduce depressive symptomatology.

What determines physical, mental and emotional workloads on nurses? A cross-sectional study.

AIM: This study aimed to identify determinants of physical, mental and emotional nursing workloads. BACKGROUND: Workload has a physical, mental and emotional dimension. It influences employees' well-being and quality of care. Nevertheless, studies of specific predictors for each dimension of nurses' workload are scarce. METHODS: We used a cross-sectional prospective design based on the Job Demand-Resources theory. We asked nurses to describe workload perceived at the end of every shift over three consecutive weeks. Data were gathered from two academic hospitals, in seven medical-surgical wards. We received 259 responses and tested 2 multivariate regression models. RESULTS: Physical workload was predicted from all variables tested; mental workload was determined by patient complexity or isolation, adequacy of nurse staffing and skill-mix, and unscheduled activities; and emotional workload was predicted by all variables except adequacy of staffing and other people's education. CONCLUSIONS: Patient, nurse and workflow aspects influenced nurse's shift workload differently for each specific dimension. IMPLICATIONS FOR NURSING MANAGEMENT: Measurement and definition of predictors of workload in the work environment are essential. Recognizing the determinants of specific dimensions of workload facilitates identification of the most appropriate interventions to improve nurses' well-being in health care settings.

Psychometric Properties of the Persian Version of Cardiovascular Management Self-efficacy Scale.

BACKGROUND: Self-efficacy plays a major role in the management of cardiovascular disease (CVD). The original Cardiovascular Management Self-efficacy Scale (CMSS) was developed in 2016 in Italian patients with CVD; however, no such scale exists for Iranian patients with CVD. OBJECTIVE: We translated the CMSS into Persian and assessed its validity, reliability, and psychometric properties in Iranian patients with CVD. METHODS: This study was conducted for 4 months in 2017 on a group of consenting patients with CVD (N = 363) recruited from a cardiovascular hospital in Kermanshah, Iran. The reliability of the Persian CMSS was evaluated. We assessed validity, including face, content, construct, convergent, divergent, and discriminate validity, using the General Self-efficacy Scale, the Hospital Anxiety and Depression Scale, and the 36-item Short Form Health Survey Scale. Known-group validity was assessed among patients with high blood pressure. RESULTS: The Persian CMSS had acceptable face and content validity. No floor or ceiling effects were found for the total scale. Cronbach α was calculated as .68. Test-retest reliability was confirmed by intraclass correlation coefficient (ICC1,3 = 0.98, P < .001). Using exploratory factor analysis, 3 subscales were identified, similar to the original version. Significant correlations were found between the Persian CMSS and both the General Self-efficacy Scale (r = 0.94, P < .001) and Hospital Anxiety and Depression Scale (r = -0.35, P < .05). Self-efficacy measured using the Persian CMSS was statistically different between 2 levels of patients' health status (P < .05). Patients with hypertension had a lower level of self-efficacy than those in the healthy group (P < .05). CONCLUSIONS: The Persian version of CMSS provides a practical, reliable, and valid scale for evaluating self-efficacy in the clinical management of Persian Iranian patients with CVD.

Stroke disease-specific quality of life trajectories after rehabilitation discharge and their sociodemographic and clinical associations: A longitudinal, multicentre study.

AIM: To investigate the longitudinal growth trajectories of disease-specific quality of life (QoL) dimensions and their associations over 1 year. DESIGN: A longitudinal design. Data were collected between February 2015-May 2017. METHODS: Four hundred and fifteen stroke survivors (mean age 70.6 years; 81% ischaemic stroke) were recruited after discharge from rehabilitation hospitals and were followed up every 3 months for 1 year. Changes in Stroke Impact Scale (SIS) dimension scores were evaluated using hierarchical linear models (HLMs) and linear, logarithmic, quadratic, and cubic time slope. RESULTS: We observed a significant linear and quadratic increase in most SIS dimensions from the baseline to 12-month follow-up, especially in physical dimensions. The communication dimension was stable over time, while the memory dimension increased only linearly. Higher physical dimension scores were significantly associated with lower age, hypercholesterolaemia, and better physical functioning at baseline, while higher communication was associated with lower age, better physical functioning, and a diagnosis of peripheral vascular disease. Better memory was associated with lower age, married status, better physical functioning, and left-hemisphere stroke. Better participation was associated with lower age and better physical functioning. No significant associations were observed for emotion. CONCLUSIONS: This study provides important information about the trajectories of stroke survivors' specific QoL and their associated variables. IMPACT: Stroke has a great impact on stroke survivors' QoL. Disease-specific QoL significantly increases from the baseline to 12-month follow-up, especially in physical dimensions. Lower age, hypercholesterolaemia, better physical functioning, and diagnosis of peripheral vascular disease seem to be associated with better QoL. Through the analyses of associated variables, we identified stroke survivors who are more at risk and who need more tailored interventions to improve their physical, psychological, emotional, and social dimensions.

Self-reported reflective functioning mediates the association between attachment insecurity and well-being among psychotherapists.

Objective: Subjective well-being is a crucial variable for mental health practitioners. This study examines the influence of therapists' attachment dimensions and self-reported reflective functioning on their perceived well-being. Further, it examines if reflective functioning mediates the association between attachment insecurity and well-being. Method: A total of 416 experienced psychotherapists were enrolled in this cross-sectional study, and completed self-report measures of attachment insecurity, reflective functioning, and well-being. We tested the hypothesized mediation model with path analysis that examined indirect effects. Results: Both attachment anxiety and avoidance dimensions had a significant negative association with perceived well-being with small to medium effects. "Certainty" in reflective functioning had a small positive effect on therapist well-being. Reflective functioning mediated the association between insecure attachment dimensions and well-being, suggesting that therapist's lower ability to mentalize may partially account for the effects of higher attachment insecurity on lower well-being. Conclusion: The well-being of psychotherapists with greater insecure attachment may deserve special attention, and therapists' mentalizing capacities may be targeted by researchers and trainers as a core ability to be cultivated in order to preserve therapists' professional and personal resources.

The ONETEP linear-scaling density functional theory program.

We present an overview of the onetep program for linear-scaling density functional theory (DFT) calculations with large basis set (plane-wave) accuracy on parallel computers. The DFT energy is computed from the density matrix, which is constructed from spatially localized orbitals we call Non-orthogonal Generalized Wannier Functions (NGWFs), expressed in terms of periodic sinc (psinc) functions. During the calculation, both the density matrix and the NGWFs are optimized with localization constraints. By taking advantage of localization, onetep is able to perform calculations including thousands of atoms with computational effort, which scales linearly with the number or atoms. The code has a large and diverse range of capabilities, explored in this paper, including different boundary conditions, various exchange-correlation functionals (with and without exact exchange), finite electronic temperature methods for metallic systems, methods for strongly correlated systems, molecular dynamics, vibrational calculations, time-dependent DFT, electronic transport, core loss spectroscopy, implicit solvation, quantum mechanical (QM)/molecular mechanical and QM-in-QM embedding, density of states calculations, distributed multipole analysis, and methods for partitioning charges and interactions between fragments. Calculations with onetep provide unique insights into large and complex systems that require an accurate atomic-level description, ranging from biomolecular to chemical, to materials, and to physical problems, as we show with a small selection of illustrative examples. onetep has always aimed to be at the cutting edge of method and software developments, and it serves as a platform for developing new methods of electronic structure simulation. We therefore conclude by describing some of the challenges and directions for its future developments and applications.

What hypertensive patients want to know [and from whom] about their disease: a two-year longitudinal study.

BACKGROUND: This study explored both the evolution of the information needs and the perceived relevance of different health information sources in patients with essential hypertension. It also investigated the relationships between information needs and the perceived relevance of information sources with socio-demographic and clinical variables. METHODS: Two hundred and two patients with essential arterial hypertension were enrolled in the study and evaluated at baseline and during three follow-ups at 6, 12 and 24 months after baseline. Patients had a mean age of 54.3 years [range 21-78; SD = 10.4], and 43% were women. Repeated measures ANOVA, Bonferroni post hoc tests, and Cochran's Q Test were performed to test differences in variables of interest over time. RESULTS: It was observed a significant reduction in all the domains of information needs related to disease management except for pharmacological treatment and risks and complications. At baseline, patients reported receiving health information primarily from specialists, general practitioners, relatives, and television, but the use of these sources decreased over time, even if the decrease was significant only for relatives. Multiple patterns of relationships were found between information needs and the perceived relevance of sources of information and socio-demographics and clinical variables, both at baseline and over time. CONCLUSIONS: The findings showed a general decrease in both the desire for information and the perceived relevance of different information sources. Hypertensive patients appeared to show little interest in health communication topics as their disease progressed. Understanding patients' information needs and the perceived relevance of different information sources is the first step in implementing tailored communication strategies that can promote patients' self-management skills and optimal clinical outcomes.

ARCUATE NERVE FIBER LAYER CHANGES AFTER INTERNAL LIMITING MEMBRANE PEELING IN IDIOPATHIC EPIRETINAL MEMBRANE.

PURPOSE: To analyze the relationship between swelling of the arcuate nerve fiber layer (SANFL) and long-term decrease of retinal nerve fiber layer thickness after internal limiting membrane peeling for idiopathic epiretinal membrane, and to investigate if SANFL is related to a mechanical surgical damage. METHODS: Prospective, interventional consecutive case series of 46 eyes that underwent combined epiretinal membrane/internal limiting membrane peeling for idiopathic epiretinal membrane. Infrared, blue autofluorescence, color fundus imaging and measurement of retinal nerve fiber layer thickness in six peripapillary sectors by spectral-domain optical coherence tomography were performed preoperatively and at 2 weeks, 1, 3, 6, and 12 months after surgery. The presence of SANFL was checked postoperatively on infrared and blue autofluorescence fundus imaging, and the extent of each SANFL was measured on infrared fundus images. RESULTS: Areas of SANFL were identified in 39 eyes (84.8%) at 2-week follow-up. Retinal nerve fiber layer thickness significantly decreased in the temporal sectors at 1, 6, and 12 months (P < 0.0001). The linear extent of SANFL was significantly correlated with the percentage of reduction in retinal nerve fiber layer thickness in the temporal (R = 0.45; P < 0.0001) and infero-temporal (R = 0.23; P = 0.0008) sectors at 12 months of follow-up. Correspondence between sites of surgical grasping and the points of origin of SANFL was demonstrated on blue autofluorescence fundus images superimposed on intraoperative surgical frames. CONCLUSION: Early postoperative SANFL is correlated with late focal retinal nerve fiber layer thinning in the temporal sectors. Intraoperative surgical grasping seems to be a leading factor for the onset of SANFL.

Trajectories of Self-Care Confidence and Maintenance in Adults with Heart Failure: A Latent Class Growth Analysis.

PURPOSE: Heart failure (HF) affects up to 14% of the elderly population and its prevalence is increasing. Self-care is fundamental to living successfully with this syndrome, but little is known about how self-care evolves over time. The present study aimed to (a) identify longitudinal trajectories of self-care confidence and maintenance among HF patients, (b) investigate whether each trajectory is characterized by specific sociodemographic and clinical patients' characteristics, and (c) assess the association between the self-care confidence and maintenance trajectories. METHOD: We conducted a prospective descriptive study of 225 HF patients followed for 6 months with data collected at baseline and 3 and 6 months. Latent class growth analysis (LCGA) was used to identify longitudinal trajectories. ANOVA and contingency tables were used to characterize trajectories and investigate their association. RESULTS: Three self-care confidence (persistently poor, increasingly adequate, and increasingly optimal) and three self-care maintenance (persistently poor, borderline but improving, and increasingly good) trajectories were identified. Married individuals were less likely to be in the persistently poor trajectory of self-care confidence. Patients with persistently poor self-care maintenance took fewer medications than patients with one of the better self-care maintenance trajectories. The two sets of trajectories were significantly and meaningfully associated. CONCLUSION: Patients in a poor self-care trajectory (confidence or maintenance) are at high risk to stay there without improving over time. These results can be used to develop tailored and potentially more effective health care interventions.

A longitudinal study on the information needs and preferences of patients after an acute coronary syndrome.

BACKGROUND: Research has shown that the provision of pertinent health information to patients with cardiovascular disease is associated with better adherence to medical prescriptions, behavioral changes, and enhanced perception of control over the disease. Yet there is no clear knowledge on how to improve information pertinence. Identifying and meeting the information needs of patients and their preferences for sources of information is pivotal to developing patient-led services. This prospective, observational study was aimed at exploring the information needs and perceived relevance of different information sources for patients during the twenty-four months following an acute coronary syndrome. METHODS: Two hundred and seventeen newly diagnosed patients with acute coronary syndrome were enrolled in the study. The patients were primarily men (83.41 %) with a mean age of 57.28 years (range 35-75; SD = 7.98). Patients' needs for information and the perceived relevance of information sources were evaluated between 2 and 8 weeks after hospitalization (baseline) and during three follow-ups at 6, 12 and 24 months after baseline. Repeated measures ANOVA, Bonferroni post hoc tests and Cochran's Q Test were performed to test differences in variables of interest over time. RESULTS: Results showed a reduction in information needs, but this decrease was significant only for topics related to daily activities, behavioral habits, risk and complication. At baseline, the primary sources of information were specialists and general practitioners, followed by family members and information leaflets given by physicians. Relevance of other sources changed differently over time. CONCLUSION: The present longitudinal study is an original contribution to the investigation of changes in information needs and preferences for sources of information among patients who are diagnosed with acute coronary syndrome. One of the main results of this study is that information on self-disease management is perceived as a minor theme for patients even two years after the event. Knowledge on how patients' information needs and perceived relevance of information sources change over time could enhance the quality of chronic disease management, leading health-care systems to move toward more patient-tailored care.

Social support and adherence to treatment in hypertensive patients: a meta-analysis.

BACKGROUND: It is important to examine factors associated with patient adherence to hypertension control strategies. PURPOSE: A meta-analysis was conducted to examine whether social support was related to adherence to healthy lifestyle and treatment medication in hypertensive patients. METHODS: Journal articles were searched in medical (CINAHL, MEDLINE), psychological (PsycINFO, PsycARTICLES), and educational (ERIC) electronic databases; in reference lists of selected papers; and in the reference list of a previous review. RESULTS: Findings of a set of meta-analyses indicated that (a) structural social support was not significantly related to overall adherence, (b) functional social support was significantly and positively related to overall adherence, (c) these findings were further confirmed in meta-analyses conducted on specific types of adherence, and (d) most results were characterized by heterogeneity across studies that was partially explained by moderator analyses. CONCLUSIONS: Functional social support, but not structural social support, was associated with adherence in hypertensive patients.

Cardiovascular Management Self-efficacy: Psychometric Properties of a New Scale and Its Usefulness in a Rehabilitation Context.

BACKGROUND: Self-efficacy beliefs have been shown to affect various effective health-promoting behaviors in patients. Unfortunately, availability of reliable and valid measures of self-efficacy in cardiovascular diseases (CVDs) is still very limited. PURPOSE: The aims of this study were to present a new scale measuring self-efficacy beliefs in managing CVD and to examine its psychometric properties. METHODS: The study involved 172 patients (mean age = 66.4 years; SD = 9.99 years; 76.2% men) undergoing cardiovascular rehabilitation. Various psychological factors and CVD severity indicators were collected. RESULTS: An Exploratory Structural Equation Model showed that the Cardiovascular Management Self-efficacy Scale has three factors: Cardiac Risk Factors, Adherence to Therapy, and Recognition of Symptoms. They all showed high internal consistency, and good convergent, discriminant, and predictive validity. Furthermore, these factors showed significant relations with CVD severity indicators. CONCLUSIONS: The Cardiovascular Management Self-efficacy Scale could be a helpful instrument to monitor differences during interventions to improve good disease management.

Smoking behavior: a cross-sectional study to assess the dimensionality of the brief Wisconsin inventory of smoking dependence motives and identify different typologies among young daily smokers.

INTRODUCTION: The present study aims to investigate the dimensionality of the brief version of the Wisconsin Inventory of Smoking Dependence Motives (B-WISDM) and identify different smoking motivational profiles among young daily smokers (N = 375). METHODS: We tested 3 measurement models of the B-WISDM using confirmatory factor analysis, whereas cluster analysis was used to identify the smokers' motivational profiles. Furthermore, we compared clusters toward dependence level and the number of cigarettes smoked per day using analysis of variance tests. RESULTS: The results confirmed that the B-WISDM measures 11 first-order intercorrelated factors. The second-order model, originally proposed for the longer version of the questionnaire, showed adequate fit indices but fitted the data significantly worse than the first-order model. Five motivational clusters were identified and differed in terms of tobacco addiction and the number of cigarettes smoked per day. Although each cluster had specific features, 2 main smoker groups were distinguished: Group A (composed of 3 clusters), which was mainly characterized by high levels of secondary dependence motives, and Group B (composed of 2 clusters), in which the primary and secondary dependence motives reached similar levels. In general, the clusters of Group B were more addicted to cigarettes than Group A clusters. CONCLUSIONS: Using the B-WISDM to identify different smoking motivational profiles has important practical implications because they might help characterize addiction, which represents the first step to help an individual quit smoking.

The influence of illness severity on health satisfaction in patients with cardiovascular disease: the mediating role of illness perception and self-efficacy beliefs.

The importance of psychological factors in improving conditions of cardiovascular disease (CVD) patients is stressed by the guidelines for their prevention and rehabilitation, but little is known about the impact of illness severity on patients' well-being, and on the psychosocial variables that may mediate this association. The aim of this study was to investigate the role of illness perception and self-efficacy beliefs on the relationship between illness severity and health satisfaction in 75 CVD patients undergoing rehabilitation (80% men; mean age = 65.44) at the St. Luca Hospital, Istituto Auxologico Italiano, Milan, Italy. Illness severity was measured in terms of left ventricular ejection fraction; psychological factors were assessed at the beginning and end of rehabilitation. Results from path analyses showed that the relationships among CVD severity and health satisfaction were mediated by illness perception and self-efficacy beliefs. Findings underscored the importance of considering illness representations and self-efficacy beliefs to improve well-being in CVD patients.

Brief report: Assessing dispositional optimism in adolescence--factor structure and concurrent validity of the Life Orientation Test--Revised.

Dispositional optimism is an individual difference promoting psychosocial adjustment and well-being during adolescence. Dispositional optimism was originally defined as a one-dimensional construct; however, empirical evidence suggests two correlated factors in the Life Orientation Test - Revised (LOT-R). The main aim of the study was to evaluate the dimensionality of the LOT-R. This study is the first attempt to identify the best factor structure, comparing congeneric, two correlated-factor, and two orthogonal-factor models in a sample of adolescents. Concurrent validity was also assessed. The results demonstrated the superior fit of the two orthogonal-factor model thus reconciling the one-dimensional definition of dispositional optimism with the bi-dimensionality of the LOT-R. Moreover, the results of correlational analyses proved the concurrent validity of this self-report measure: optimism is moderately related to indices of psychosocial adjustment and well-being. Thus, the LOT-R is a useful, valid, and reliable self-report measure to properly assess optimism in adolescence.
