The implementation and effectiveness of Integrated Psychological Therapy (IPT) in chronic middle-aged inpatients with schizophrenia.

Introduction: Cognitive rehabilitation is essential for schizophrenia treatment since it improves function. Moreover, the relationship between cognitive rehabilitation and functioning is significantly affected by negative symptoms and social cognition. Integrated Psychological Therapy (IPT) is a promising approach that integrates interventions in neurocognition, social cognition, and functional level.

Transitivity as Skinnerian problem solving controlled by self-constructed relational stimuli.

In tests of the derivation of complex relations such as transitivity, extant cues might fail to evoke effective responding, necessitating the construction of supplemental stimuli prior to their solution. The significance of this process was investigated by within-subject manipulation of an instructional variable designed to produce different levels of construction of supplemental stimulation concerning relationships among stimulus elements of concatenated conditional discriminations. In two experimental sessions, serial training of three 5-member stimulus classes occurred, either with the instruction to simply name the component stimuli or to both name them and generate a tale serially linking the stimuli named; such constructed stimuli might be spontaneously reconstructed by precurrent acts in subsequent tests of "emergent" relations.

Episodic Visual Learning/Memory and Attentional Flexibility in Patients With Major Depressive Disorder After Clinically Effective Electroconvulsive Therapy.

Objectives: This study is a follow-up of a previous one reporting that the neuropsychological profile of pharmacoresistant patients with major depressive disorder referred for electroconvulsive therapy (ECT, ECT group) contrasted with that of their pharmacorespondent counterparts (NECT group). The NECT group exhibited severe visuospatial memory and minor executive deficits; the ECT group presented the reverse pattern. In that same ECT group, the current follow-up study examined the effects of clinically effective ECT on both cognitive domains 2 months later.

Psychological distress following wildfires disaster in a rural part of Greece: a case-control population-based study.

Psychological distress is common in the aftermath of a disaster. This study investigated psychological distress and morbidity in individuals who had experienced severe exposure to a wildfire disaster in a part of Greece. The study was a cross sectional case control of an adult population (18-65 years old).

Parental educational practices in relation to children's anxiety disorder-related behavior.

Schoolchildren reported their parents' use of aversive control and positive reinforcement contingencies in their educational interventions, as well as parental non-responsiveness to their requests for educational assistance. They also reported their own levels of six dimensions of anxiety disorder-related phenomena. Both parental use of aversive control and non-responsiveness were directly related to overall levels of child anxiety disorder-related behavior; these correlations were more robust than those observed in previous investigations of more diffuse dimensions of parenting style and trait anxiety.

Superstitious perception: response-independent reinforcement and punishment as determinants of recurring eccentric interpretations.

This study provided controlled observations of a potential mechanism for the determination of the repetitive, aberrant perceptions or interpretations of everyday events that figure prominently in a range of psychological disorders: the adventitious reinforcement of acts of cognition by the actual consequences of concurrent motor acts. Adults made a series of two-choice brightness discriminations; on 60% of trials, choosing the brighter stimulus produced a "correct" signal while errors produced an aversive sound. On 40% of trials, the choice stimuli did not in fact differ in brightness; the consequences of responding on these "identical stimuli" trials differed across blocks of trials.

Locus of control and psychopathology in relation to levels of trauma and loss: self-reports of Peloponnesian wildfire survivors.

This study investigated whether relations between beliefs about the personal controllability of reinforcing events and levels of psychopathology were differentiated with respect to levels of trauma and loss experienced in a series of devastating wildfires. In contrast with studies of combat veterans and professional firefighters, in wildfire survivors external locus of control beliefs and psychopathology were correlated only in respondents who experienced higher levels of trauma and loss; specifically, for residents of designated disaster areas (N = 409), but not for a demographically matched sample of residents of adjacent, non-fire-damaged areas (N = 391). The conflicting findings across studies are interpreted with respect to probable differences in contingencies of reinforcement for causal attributions in professionals and in novices in disaster management.

Identification of recycled water with an empirically derived symbol increases its probability of use.

The experiment described in this paper compared the effects of two systems for labeling recycled water on potential consumers' intention to use this resource; the current identifying symbol used worldwide (purple color for pipes, containers, and tanks) and a new, empirically derived and validated set of symbols that provide specific information on water quality and positive comparative information. In total, 807 face-to-face surveys were carried out. Subjects were asked to rate their intentions for using different qualities of recycled water for commercial agriculture as well as for using products and facilities irrigated with recycled water, either in the presence of the established symbol or the new, empirically derived symbols.

Structure, developmental course, and correlates of children's anxiety disorder-related behavior in a Hellenic community sample.

The generality of the DSM-IV diagnostic structure for children's anxiety disorders, as measured by the Spence Children's Anxiety Scale (SCAS) was investigated with a Greek-language version of the scale. An exploratory factor analysis produced a six-factor solution in general accord with the DSM-IV-based theoretical structure of responding. However, a generalized anxiety factor incorporated three unexpected items interpreted as representing excessive worry, including two items intended to measure obsessions, raising the question of children's ability to discriminate the intrusiveness of vexatious cognition.
