Implicit and Explicit Self-Esteem Discrepancies in Paranoia and Depression

The main purpose of the present study was to examine implicit and explicit self-esteem (SE) in patients with persecutory delusions. In samples of paranoid patients, depressed patients, and healthy controls, implicit SE was assessed using the experimental go/no-go association task, whereas explicit SE was measured using 2 self-reporting questionnaires: the self-worth subscale of the World Assumption Scale (Janoff-Bulman, 1989) and the self-acceptance subscale of the Scales of Psychological Well-Being (Ryff & Keyes, 1995). Our analysis revealed that depressed patients showed lower explicit SE than did paranoid and healthy control participants. However, participants with persecutory delusions had significantly lower implicit SE scores than did healthy controls. We interpret the discrepancies observed between overt and covert measures in the paranoid group as psychological defense mechanisms. The present study stresses the clinical and theoretical importance of the use of implicit measures in psychopathology.

Predictors of subjective well-being in patients with paranoid symptoms: Is insight necessarily advantageous?

In schizophrenia, poor insight has been associated with negative outcome. In fact, some studies have found insight to be associated with greater treatment adherence and lower levels of symptomatology, as well as better psychosocial functioning. However, others have found that insight into illness is associated with an increase in depression, low self-esteem, and possibly higher risk of suicide. We investigated the relationship between insight and well-being in a sample of 40 people presenting paranoid symptoms and diagnosed with schizophrenia or other psychotic disorder. Independent-samples t-tests revealed that compared to a paranoid group with high insight, paranoid participants with low insight had more self-acceptance, higher sense of autonomy and personal growth, and greater orientation towards gratification. Moderation analyses showed that when experiential avoidance was high, insight into paranoia had a detrimental effect on self-acceptance. Overall, our results support the need to explore which psychological variables moderate insight in patients with persecutory beliefs. We discuss the implications of these results for the research of paranoia.

Differences in emotional personality traits and stress between sustained hypertension and normotension.

This study was aimed at determining whether there are differences in emotional personality traits and psychosocial stress between hypertension and normotension. From a large community sample of adults, 14 individuals having hypertension and showing clinic blood pressures (BP) ⩾140/90 mm Hg and self-measured BPs ⩾135/85 mm Hg (sustained hypertensives) were selected and compared with a sex- and age-matched group of 14 individuals with normotension (clinic BPs <140/90 mm Hg and self-measured BPs <135/85 mm Hg) on measures of trait anxiety, trait depression, trait anger and stress derived from standardized questionnaires. There were no significant differences between hypertensives and normotensives on trait anger, but, in line with hypotheses, the sustained hypertensive group showed higher levels of trait anxiety, trait depression and stress than did the normotensive group. A discriminant analysis revealed that trait depression was the most important psychological variable to discriminate between sustained hypertension and normotension. Results provide support to the hypothesized relationship of emotional personality traits and stress with hypertension, and underscore the need to define hypertension on the basis of both clinic and home/ambulatory BP measurements and to simultaneously evaluate all relevant negative emotional constructs, when conducting research on psychological factors in hypertension.

World assumptions in psychosis: do paranoid patients believe in a just world?

The aim of this study was to examine the contents of world views held by patients with current persecutory beliefs. We examined whether these beliefs in a just world (BJW) were associated with the severity of psychopathology of participants. Our results showed that, compared with a healthy control group, the current persecutory beliefs group had weaker beliefs in a just world related to themselves (BJW-P), but there were no differences between both groups in their beliefs in general justice in the world (BJW-G). Regression analyses showed that BJW, particularly weaker beliefs in personal justice, significantly associated with more severe symptoms of depression and paranoia as well as with lower scores of psychological well-being. Our results support the relevance of the BJW framework in exploring world views in patients with persecutory beliefs. We discuss the implications of these results for the research and treatment of paranoid ideation.

Differences in personality between sustained hypertension, isolated clinic hypertension and normotension

The aim of this study was to determine whether there are differences in personality between hypertension and normotension. Forty‐two male patients with essential hypertension were divided into two groups after self‐assessment of blood pressure, 18 with sustained hypertension and 24 with isolated clinic (white coat) hypertension, and were compared with 25 men with normotension on Spielbergers State‐Trait Anxiety Inventory and the Jenkins Activity Survey. In line with hypotheses, the sustained hypertensive group showed higher levels of trait anxiety, Type A behaviour pattern, and hard‐driving behaviours/competitiveness than the normotensive group, whereas isolated clinic hypertensives occupied an intermediate position between those two groups. Results provide support to the hypothesised relationship between personality and hypertension and stress the need of distinguishing sustained hypertension from isolated clinic hypertension.

Can blood pressure measurements taken in the physician's office avoid the 'white coat' bias?

ObjectiveObtaining an accurate blood pressure (BP) reading is vital for diagnosing hypertension. However, BP measures taken in the physician’s clinic (CBP) are subject to the ‘white coat’ bias. Measurements taken outside the office using ambulatory (ABP) and home (HBP) monitoring are superior predictors of cardiovascular diseases compared with CBP, but ABP remains underutilized because of the effort and expense involved. Unfortunately, HBP has limitations, including questionable device validity and patient compliance. Thus, it is important to identify feasible alternative techniques to measure BP in the office that will increase the accuracy of the diagnosis. MethodsAuscultatory BP was measured in 249 patients in a nonclinical setting by trained technicians (NCBP); on the following day, patients were taken to their physician (CBP). They were also given an HBP monitor, and a 36 h ABP monitoring. Because ABP is considered the gold standard for prediction of cardiovascular disease, these readings were used as the criterion in a statistical model in which CBP, HBP, and NCBP were entered as predictors. The level of agreement between measurements was estimated. ResultsMultiple regression analysis showed that HBP and NCBP (P<0.001) explained 94 and 87% of the variance in systolic and diastolic ABP, respectively. The agreement between NCBP and ABP was greater than that between CBP and ABP or between HBP. ConclusionWhen ABP monitoring and HBP monitoring are not options, the NCBP at the clinic can avoid the white coat bias and therefore improve diagnosis.

Recovery style and stigma in psychosis: the healing power of integrating

ABSTRACT Introduction. Persecutory delusions are a very common symptom in psychotic disorders and represent a considerable cost for both patients and for society. The way in which a person faces their psychotic disorder (i.e., recovery style) has impact on their recovery. The impact of coping style as a moderator in the course of their illness has not been studied sufficiently in persecutory delusions. In addition, internalised stigma is a common process in psychosis that not only might affect emotional distress, but might also shape recovery style. The goal of this study was to examine the moderator role of recovery style between internalised stigma and emotional distress in people with persecutory delusions. Methods. All 50 people with persecutory beliefs were assessed by the Recovery Style Questionnaire, the Beck Anxiety Inventory, Beck Depression Inventory, Second Edition, and Internalised Stigma of Mental Illness. Results. Moderation analysis showed that participants with a sealing-over recovery style had high levels of depression when they experienced internalised stigma and low levels of depression only when internalised stigma was low. However, participants with an integration recovery style presented similar levels of depression regardless of the level of their internalised stigma. Conclusions. Findings suggest the moderator role of recovery style between internalised stigma and depression in people with persecutory delusions.

Stress induced by the socially evaluated cold-pressor test cause equivalent deficiencies of sensory gating in male subjects with schizophrenia and healthy controls

It is known that patients with schizophrenia show a deficiency in the prepulse inhibition reflex (PPI). These patients display abnormalities in autonomic nervous system and hypothalamic-pituitary-adrenal function and may have an altered sensitivity to stress. To date, no studies have been carried out to determine the effect of acute stress on the PPI. We investigated whether there was a differential response in reactivity to acute stress caused by the socially evaluated cold-pressor test (SECPT) in a sample of 58 chronic male patients with schizophrenia and 28 healthy control subjects. PPI, salivary cortisol and heart rate (HR) were measured. The patients were evaluated in two sessions (with and without the SECPT) 72 h apart and basal measurements were carried out and 30 min post-startle probe. We found an increase in salivary cortisol levels and the HR with SECPT condition in both groups and a significantly lower PPI% in patients with schizophrenia. The most relevant findings of this study are that the impairment of the PPI is increased by stress. Stress-induced increase in cortisol in both groups, mainly in healthy control group which allows us to hypothesize that at least such deterioration may be due to the hypercortisolemia caused by the SECPT.
