Fattori che modulano i processi decisionali: uno studio sull’effetto framing

Lo studio prende in considerazione il cosiddetto “effetto framing”, definito come il contesto in cui l’individuo si trova a operare una scelta. Nello specifico, il modo in cui un problema decisionale è formulato influisce sulla percezione del punto di partenza del problema, rispetto al quale valutare i possibili esiti delle proprie azioni. Lo studio ha indagato l’entità e le caratteristiche dell’effetto framing in soggetti sani e in pazienti con esiti di grave cerebrolesione acquisita (GCA) ed ha esaminato le possibili relazioni tra tale effetto e alcuni processi cognitivi che si ritiene siano alla base dei processi decisionali. Sono state quindi valutate caratteristiche neuropsicologiche (working memory, funzioni attentive ed esecutive) e neuropsichiatriche (impulsività/disinibizione in particolare), ipotizzando che la presenza dell’effetto framing sia direttamente correlata a quella dei disturbi neuropsicologici e di personalità eventualmente presenti. Tutti i partecipanti sani che i pazienti sono stati esaminati mediante test neuropsicologici, scale cliniche e una prova computerizzata costruita ad hoc. I risultati hanno evidenziato la presenza degli effetti attesi, con un aumento di tale effetto nel gruppo dei pazienti con GCA, ponendo rilievo nella pratica clinica agli aspetti decisionali che incidono sulla qualità della loro vita e dell’intero sistema familiare. Questo è l’unico studio in cui una procedura che richiede di inibire attivamente le risposte automatiche, viene utilizzata per indagare i processi cognitivi coinvolti nell’effetto framing. In conclusione, raccolte insieme, le precedenti scoperte e i nostri primi risultati, forniscono evidenze convergenti a partire da paradigmi sperimentali differenti che supportano l’ipotesi secondo cui l’attivazione di un sistema esecutivo-analitico (caratterizzato da processi controllati, deliberati e cognitivi) possa influenzare i processi decisionali in condizione di framing

Pharmacological treatment of pain and agitation in severe dementia and responsiveness to change of the Italian Mobilization-Observation-Behavior-Intensity-Dementia (I-MOBID2) Pain Scale: study protocol

Up to 80% of Alzheimer's disease (AD) patients in nursing homes experiences chronic pain and 97% develops fluctuant neuropsychiatric symptoms (NPS). Agitation, associated with unrelieved pain, is managed through antipsychotics and may increase the risk of death. Evidence is accumulating in favor of analgesia for a safer, effective therapy of agitation. The Italian version of Mobilization-Observation-Behavior-Intensity-Dementia, I-MOBID2, recently validated in the Italian setting, shows: good scale content validity index (0.89), high construct validity (Spearman rank-order correlation Rho = 0.748), reliable internal consistency (Cronbach's α coefficient = 0.751), good-excellent inter-rater (intraclass correlation coefficient, ICC = 0.778) and test-retest (ICC = 0.902) reliability, and good inter-rater and test-retest agreement (Cohen's K = 0.744) with 5.8 min completion time. This study intends to identify the responsiveness of the I-MOBID2 based on COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) recommendations, assessing the a priori hypotheses of (1) the efficacy of painkillers administered to severe AD patients after proper pain assessment and (2) the effect of reduction of the Cohen-Mansfield Agitation Inventory (CMAI) score and of agitation rescue medications. This protocol is approved by Calabria Region Ethics Committee protocol No. 31/2017 and follows the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) guidelines

Language-Related Brain Potentials in Patients With Disorders of Consciousness: A Follow-up Study to Detect “Covert” Language Disorders

Background. Language disorders may occur in patients with disorders of consciousness (DoCs), and they could interfere with the behavioral assessment of consciousness and responsiveness. Objective. In this study, we retrospectively explored whether ERP N400 was eventually associated with the presence of aphasia diagnosed in those patients who had evolved into Exit-Minimally Conscious State (E-MCS) at the clinical follow-up. Methods. In this retrospective cohort study, the ERPs elicited by an auditory sentences task were retrospectively examined in a sample of 15 DoC patients diagnosed according to the Coma Recovery Scale–Revised (CRS-R). All these 15 DoC patients underwent a (at least) 1-year clinical follow-up, which included a neuropsychological evaluation to assess language function among other cognitive functions. Ten healthy individuals also underwent the same paradigm to investigate the variability of ERPs characteristics. Results. The N400 ERP component with centroparietal topography was found in 9 of 10 healthy controls in response to the ill-formed sentences. Analysis of patients’ data revealed that (1) a significant N400 component could be detected in 64% (9 of 14 patients) of the DoC patients regardless of the type of DoC; (2) no significant N400 ERP component was retrospectively detected in those E-MCS patients who showed aphasia at the follow-up; and (3) the presence/absence of the N400-ERP component was consistent with the brain lesion side and significantly predict the recovery. Conclusion. These preliminary findings indicate that the absence of N400 was significantly associated with the presence of aphasia diagnosed at the clinical follow-up in E-MCS patients

Pain and agitation treatment in severe dementia patients: The need for Italian Mobilization-Observation-Behavior-Intensity-Dementia (I-MOBID2) pain scale translation, adaptation and validation with psychometric testing

The 97% of dementia patients develops fluctuant neuropsychiatric symptoms often related to under-diagnosed and unrelieved pain. Up to 80% severe demented nursing home residents experiences chronic pain due to age-related comorbidities. Patients lacking self-report skills risk not to be appropriately treated for pain. Mobilization-Observation-Behavior-Intensity-Dementia (MOBID2) is the sole pain scale to consider the frequent co-occurrence of musculoskeletal and visceral pain and to unravel concealed pain through active guided movements. Accordingly, the Italian real-world setting can benefit from its translation and validation. This clinical study provides a translated, adapted and validated version of the MOBID2, the Italian I-MOBID2. The translation, adaptation and validation of the scale for non-verbal, severe demented patients was conducted according to current guidelines in a cohort of 11 patients over 65 with mini-mental state examination ≤ 12. The I-MOBID2 proves: good face and scale content validity index (0.89); reliable internal consistency (Cronbach's α = 0.751); good to excellent inter-rater (Intraclass correlation coefficient, and test-retest (ICC = 0.902) reliability. The construct validity is high (Rho = 0.748 p < 0.05 for 11 patients, Spearman rank order correlation of the overall pain intensity score with the maximum item score of I-MOBID2 Part 1; rho=0.895 p < 0.01 for 11 patients, for the overall pain intensity score with the maximum item score of I-MOBID2 Part 2) and a good rate of inter-rater and test-retest agreement was demonstrated by Cohen's K = 0.744. The average execution time is of 5.8 min, thus making I-MOBID2 a useful tool suitable also for future development in community setting with administration by caregivers

Psychosocial factors and major adverse cardiac and cerebrovascular events after cardiac surgery

Our aim was to prospectively examine the association of psychosocial factors with adverse outcome after cardiac surgery. One hundred and eighty cardiac surgery patients were enrolled and contacted annually by mail. Depression [Beck depression inventory (BDI)], anxiety [state anxiety subscale in Spielberger State-Trait Anxiety Inventory (STAI-S) and trait anxiety subscale in Spielberger State-Trait Anxiety Inventory (STAI-T)] were investigated annually, social support, negative affectivity, social inhibition (SI), illness intrusiveness, self-rated health and sleeping disorders were investigated by standardized tests at the second and fifth year. The end-point was the major adverse cardiac and cerebrovascular event (MACCE) including death. Twenty-eight (15.5%) patients died by the end of the fifth year. At the end of the second and fifth years, 146 (81.1%) and 118 (65.5%) patients fulfilled the tests, respectively. At the end of the second year after adjustment for medical and perioperative factors worse self-rated health [adjusted hazard ratio (AHR): 0.67, P=0.006], sleeping disorders (AHR: 1.14, P=0.001), higher illness intrusiveness (AHR: 1.03, P=0.018), higher BDI (AHR: 1.12, P=0.001), STAI-S (AHR: 1.09, P=0.001) and higher STAI-T scores (AHR: 1.08, P=0.002) showed higher risk for MACCE. Significant individual elevation in scores of sleeping disorders, illness intrusiveness and SI were observed over the three-year period in the MACCE group. Assessment of psychosocial factors could help in identifying patients at high-risk for MACCE after cardiac surgery

Racism in organizations: The case of a county public health department

Racism is part of the foundation of U.S. society and institutions, yet few studies in community psychology or organizational studies have examined how racism affects organizations. This paper proposes a conceptual framework of institutional racism, which describes how, in spite of professional standards and ethics, racism functions within organizations to adversely affect the quality of services, the organizational climate, and staff job satisfaction and morale. Grounded in systems theory and organizational empowerment, the framework is based on data that describe how racism was made manifest in a county public health department. The findings highlight the importance of understanding how organizations are influenced by external forces and can negatively affect clients, communities, and their own staff members. © 2007 Wiley Periodicals, Inc.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/55998/1/20149_ftp.pd

Perceived Stress Scale: Reliability and Validity Study in Greece

Objective: To translate the Perceived Stress Scale (versions PSS-4, -10 and -14) and to assess its psychometric properties in a sample of general Greek population. Methods: 941 individuals completed anonymously questionnaires comprising of PSS, the Depression Anxiety and Stress scale (DASS-21 version), and a list of stress-related symptoms. Psychometric properties of PSS were investigated by confirmatory factor analysis (construct validity), Cronbach’s alpha (reliability), and by investigating relations with the DASS-21 scores and the number of symptoms, across individuals’ characteristics. The two-factor structure of PSS-10 and PSS-14 was confirmed in our analysis. We found satisfactory Cronbach’s alpha values (0.82 for the full scale) for PSS-14 and PSS-10 and marginal satisfactory values for PSS-4 (0.69). PSS score exhibited high correlation coefficients with DASS-21 subscales scores, meaning stress (r = 0.64), depression (r = 0.61), and anxiety (r = 0.54). Women reported significantly more stress compared to men and divorced or widows compared to married or singled only. A strong significant (p < 0.001) positive correlation between the stress score and the number of self-reported symptoms was also noted. Conclusions: The Greek versions of the PSS-14 and PSS-10 exhibited satisfactory psychometric properties and their use for research and health care practice is warranted
