Difficulties in everyday life activities are core features of persons diagnosed with schizophrenia and in particular during multitasking activities. However, at present, patients' multitasking capacities have not been adequately examined in the literature due to an absence of suitable assessment strategies. We thus recently developed a computerized real-life activity task designed to take into account the complex and multitasking nature of certain everyday life activities where participants are required to prepare a room for a meeting. Twenty-one individuals diagnosed with schizophrenia and 20 matched healthy controls completed the computerized task. Patients were also evaluated with a cognitive battery, measures of symptomatology and real world functioning. To examine the ecological validity, 14 other patients were recruited and were given the computerized version and a real version of the meeting preparation task. Results showed that performance on the computerized task was significantly correlated with executive functioning, pointing to the major implication of these cognitive processes in multitasking situations. Performance on the computerized task also significantly predicted up to 50% of real world functioning. Moreover, the computerized task demonstrated good ecological validity. These findings suggest the importance of evaluating multitasking capacities in patients diagnosed with schizophrenia in order to predict real world functioning. [less ▲]

This study investigated patients with Bipolar Disorder’s abilities to generate specific past and future events in response to positive and negative cues words as well as emotional intensity related to these ones. The relationships between the number of generated specific events cognitive functioning, interpersonal problems and the ability to problem solving were investigated. Nineteen BD and nineteen healthy controls completed a French version of the AMT to evaluate the past and future events recall, in function of their valence, and emotions related. Furthermore, they completed the Optional Thinking Test, the Inventory of Interpersonal Problems and the neuropsychological measures. Compared to healthy controls, BD recollected (1) fewer specific past negative events and (2) fewer future specific positive and negative events furthermore, (3) they felt more emotional intensity related to future events. These results were explained in the light of theoretical models. Finally, specific past memories deficits in BD were linked with issues in problem solving but not with levels of distress arising from interpersonal problems. In view of AM functions in everyday life, all types of deficits should be taken into consideration, and AM remediation envisaged. [less ▲]

Identity results from interlock of two systems which are a set of abstracted representations about oneself and a phenomenological self. Literature highlights identity disturbance in schizophrenia that affects each of both systems. In the same vein, the present study investigates the stability and the quality of traits self-knowledge, a component of abstracted representations of self, in schizophrenia patients. Sixty-eight patients with schizophrenia and 68 healthy control subjects completed a short version of a personality scale (LABEL). This scale is composed of two versions (A and B), each comprising 50 adjectives that correspond to synonymous adjectives in the alternate list. Participants indicated how these adjectives described themselves and completed both versions of the scale on two separate occasions, one month apart. The findings showed that schizophrenic patients presented an unstable identity and change in identity quality compared with healthy subjects. However, this identity disturbance was weaker than expected. These results are discussed in a part of autobiographical memory disturbances in schizophrenia, illness duration and the decompensation stage. [less ▲]

Persons diagnosed with bipolar disorder often suffer from cognitive impairments. However, little is known concerning how these cognitive deficits impact their real world functioning. We developed a computerized real-life activity task, where participants are required to shop for a list of grocery store items. Twenty one individuals diagnosed with bipolar disorder and 21 matched healthy controls were administered the computerized shopping task. Moreover, the patient group was assessed with a battery of cognitive tests and clinical scales. Performance on the shopping task significantly differentiated patients and healthy controls for two variables: Total time to complete the shopping task and Mean time spent to consult the shopping list. Moreover, in the patient group, performance on these variables from the shopping task correlated significantly with cognitive functioning (i.e. processing speed, verbal episodic memory, planning, cognitive flexibility, and inhibition) and with clinical variables including duration of illness and real world functioning. Finally, variables from the shopping task were found to significantly explain 41% of real world functioning of patients diagnosed with bipolar disorder. These findings suggest that the shopping task provides a good indication of real world functioning and cognitive functioning of persons diagnosed with bipolar disorder. [less ▲]

Several studies have explored the link between depression and personality with classical personality questionnaires like the Revised NEO Personality Inventory and the Temperament and Character Inventory (TCI). However, no studies have been conducted with the revised form of the TCI (TCI-R). Moreover, since a few studies conducted on normal subjects suggest that Emotional Intelligence (EI) would be lower in depression, but that the concept has not been explicitly measured in patients with major depressive disorder, EI was assessed here with the modified version of Schutte's scale among a group of depressive patients. In addition, both personality and EI measures were carried out during the clinical state of depression and after the remission to assess the state versus trait aspect. The study was conducted on 54 major depressive inpatients (20 in remission) and 54 matched controls. As expected, depressive patients exhibited higher score on harm avoidance (HA), and lower scores on persistence (P), self-directedness (SD), cooperativeness (C), optimism/emotional regulation subscore, and total EI score as compared with controls. In the period of remission, patients again had elevated scores on HA, and lower scores on SD. In contrast, the total EI score did not differ between controls and depressive patients in remission. The results confirm that some personality dimensions are dependent on both state and trait aspects of depression, and suggest that EI only seems to be affected during the clinical state. [less ▲]

The current main neurochemical theories of the biological correlates of suicidal behavior involve serotonergic and, to a lesser extent, dopaminergic systems. Few data are available about the possible implication of the noradrenergic function. In the present study, we assessed the growth hormone response to clonidine, a selective alpha 2-adrenergic agonist, in 15 DSM-III-R major depressive inpatients with a history of suicide attempts, compared with 15 age- and gender-matched major depressive inpatients without a history of suicidal behavior. Mean (+/- SD) growth hormone peak responses to clonidine were significantly lower in the group of suicide attempters than in the control group: 2.93 +/- 3.01 ng/ml vs. 8.28 +/- 8.15 ng/ml. Therefore, these results suggest that a blunted growth hormone response to clonidine could be a biological correlate of suicidal behavior. [less ▲]
