To assess the long-term effectiveness of antipsychotic medications in facilitating work functioning in patients with schizophrenia we conducted longitudinal multifollowup research on 139 initially psychotic patients. The 70 patients with schizophrenia and 69 initially psychotic mood disordered control patients were followed up 6 times over 20 years. We compared the influence on work functioning of patients with schizophrenia continuously prescribed antipsychotics with patients with schizophrenia not prescribed antipsychotics, using statistical controls for inter-subject differences...

The present study examined the relationship between temporal focus profiles and scores on psychiatric symptomatology. Participants were recruited by undergraduate students in a university in the United Kingdom (N = 372; 46% male). Five clusters emerged from hierarchical cluster analysis and were labelled, No Focus, Multi Focus, Past Focus, Future Focus, and Current Focus. The worst outcomes in terms of psychiatric symptomatology were observed for those belonging to the Past Focus cluster. These results build on the only previous study using cluster analysis of Temporal Focus Scale scores, where being past focussed was associated with lower self-esteem in adolescents...

Problems involving anger and aggression are common after military deployment, and may involve abnormal responses to threat. This study therefore investigated effects on neural activation related to threat and escapability among veterans with deployment experience. Twenty-seven male veterans with anger and aggression problems (Anger group) and 30 Control veterans performed a virtual predator-task during fMRI measurement. In this task, threat and proximity were manipulated. The distance of cues determined their possibility for escape...

Blood dyscrasias excluding agranulocytosis received limited attention in antipsychotic-treated patients during the first 18 weeks of therapy, although severe clinical conditions have been reported in a few cases. We extracted data records of 285 Caucasian patients after 18 weeks of antipsychotic treatments to investigate risk factors of blood dyscrasias. We observed a higher risk to develop both transient and persistent anemia, neutrophilia and eosinophilia in clozapine-treated patients, whereas in those treated with other atypical antipsychotics when compared to a reference group under typical antipsychotics, emerged an increased risk for transient neutrophilia and eosinophilia...

The nature and severity of semantic memory (SM) impairments in schizophrenia has been related to symptoms, mainly formal thought disorder (FTD), and other clinical factors like length of illness. Symptom-related studies in schizophrenia are often confounded by clinical factors, for example medication and hospitalisations. We completed a schizotypy analogue study to examine the relationship between SM processing and FTD using an analogue schizotypy score referred to as cognitive disorganisation. Sixty individuals without a history of mental illness (M=22...

This study examined the moderating role of parental self-efficacy of the association between spousal support and stress. Recruited through online survey, 445 Israeli parents filled out self-reported questionnaires. The moderation model explained 36.4% of the variance in parents' stress. The findings confirmed that in the presence of high parental self-efficacy, the effect of spousal support on stress was non-significant. However, the less parental self-efficacy reported, the stronger the association between spousal support and stress was found...

The aim of this study was to investigate whether cardiorespiratory fitness among outpatients with bipolar disorder is associated with health related quality of life (HRQL) and explore differences versus healthy controls. Outpatients with bipolar disorder and healthy controls matched for age, sex and body mass index completed the 36-item Short Form Health Survey, the Positive-and-Negative-Affect-Schedule (PANAS), a maximal cardiorespiratory fitness test, and wore a Sensewear Armband to measure physical activity and sedentary behavior for eight days...

Clinical observation has linked externalizing coping strategies such as substance overuse and aggressive behaviours with narcissistic personality dysfunction. This study examined the relationship between pathological narcissism and maladaptive self-regulatory behaviours among Canadian men. An online survey was distributed among a stratified, nationally representative sample of 1000 men from across Canada. The survey included brief self-report measures of pathological narcissism, maladaptive externalizing coping behaviours, and general psychological distress...

Individuals who differ markedly by sleep chronotype, i.e., morning-type or evening-type also differ on a number of psychological, behavioral, and biological variables. Among several other psychological functions, dissociation may also lead to disruption and alteration of consciousness, which may facilitate dream-like experiences. Our study was aimed at an inquiry into the effects of individual biological rhythm differences on sleep quality and daytime sleepiness in conjunction with dissociative experiences...

The aim of this study is to investigate the relationship between the risk of muscle dysmorphia and psychopathological symptoms in an Italian sample of male bodybuilders. METHOD: The sample was recruited online (145 men with a mean age of 30.0 years) and participants were asked to fill out the Muscle Dysmorphic Disorder Inventory (MDDI), Symptom Cheklist-90-R (SCL-90-R), Dissociative Experiences Scale (DES-II), and to provide other socio-demographic data. Bodybuilders at risk of muscle dysmorphia display greater global psychopathology and present higher scores on all SCL-90-R dimensions when compared to bodybuilders not at risk of muscle dysmorphia...

This study explored specificity and visual perspective of mental time travel in schizophrenia. Fifteen patients with schizophrenia and 18 controls were recruited. Participants were asked to recall or imagine specific events according to cue words. Results showed that schizophrenia patients generated fewer specific events than controls, the recalled events were more specific than imagined events. Schizophrenia adopted less field perspective and more observer perspective than controls. These results suggested that patients with schizophrenia were impaired in mental time travel both in specificity and visual perspective...

The brain-derive neurotrophic factor (BDNF) may play an important role in the course of depression. We aimed to study the associations between peripheral whole blood BDNF levels in healthy individuals with and without a family history of depression. BDNF levels were significantly increased in healthy individuals with (n = 76), compared with healthy individuals without (n = 39) a family history of depression and persisted after adjustment for age and gender differences. Higher BDNF levels were associated with increasing age and seasonality...

To examine whether acute changes in cognitive empathy might mediate the impact of light therapy on mood, we assessed the effects of a single light-therapy session on mood and cognitive empathy in 48 premenstrual women, including 17 who met Premenstrual Symptoms Screening Tool criteria for moderate-to-severe premenstrual syndrome / premenstrual dysphoric disorder (PMS/PMDD). Using a participant-blind between-groups design, 23 women underwent 30min of morning light therapy (5,000lx; blue-enriched polychromatic light, 17,000K) while 25 women had a sham session (200lx, polychromatic light, 5,000K)...

Borderline personality disorder (BPD) is characterized by difficulties in emotional regulation and impulse control. In this study, we presented a novel picture-based emotional go/no-go task with distracting emotional faces in the background, which was administered to 16 patients with BPD and 16 age-matched healthy controls. The faces displayed different emotional content (angry, neutral, or happy). Results showed differences in sensitivity between patients and the control group, with patients exhibiting less sensitivity in the task, and also showed influences of emotional content represented in the distracting faces in both groups...

Tobias Teichert
Amplitudes of auditory evoked potentials (AEP) increase with the intensity/loudness of sounds (loudness-dependence of AEP, LDAEP), and the time between adjacent sounds (time-dependence of AEP, TDAEP). Both, blunted LDAEP and blunted TDAEP are markers of altered auditory function in schizophrenia (SZ). However, while blunted LDAEP has been attributed to altered serotonergic function, blunted TDAEP has been linked to altered NMDA receptor function. Despite phenomenological similarities of the two effects, no common pharmacological underpinnings have been identified...

This study explored the influence of attachment on psychiatric treatment by considering attitudes towards and the use of psychotropic medication and psychotherapy in patients with depressive and anxiety disorders. Adults referred to a psychiatrist completed self-report measures and participated in a diagnostic interview based on DSM-IV criteria. Those with depressive, anxiety or adjustment disorders were included (n = 124). Patients reported the types and dosage of current psychotropic medication as well as number of different psychiatrists and psychologists/counselors they had seen in the past 10 years...

Desire thinking and mindfulness have been associated with craving. The aim of the present study was to validate the French version of the Desire Thinking Questionnaire (DTQ) and to investigate the relationship between mindfulness, desire thinking and craving among a sample of university students. Four hundred and ninety six university students completed the DTQ and measures of mindfulness, craving and alcohol use. Results from confirmatory factor analyses showed that the two-factor structure proposed in the original DTQ exhibited suitable goodness-of-fit statistics...

Facial affect recognition (FAR) accuracy is impaired in schizophrenia and, to a lesser extent, in individuals at-risk for psychosis. Reduced reaction time and negative bias on FAR tasks are also evident in schizophrenia, though few studies have examined these measures in at-risk samples. Social dysfunction is associated with FAR deficits in schizophrenia and at-risk individuals. We aimed to elucidate the nature of FAR and social functioning among individuals from a non-clinical population reporting a range of schizotypal traits (i...
