Perceived Spirituality,Mindfulness and Quality of Life in Psychiatric Patients

There is some evidence of the relationship between spirituality and quality of life, but there are few bibliographic references on these constructs for patients suffering from mental illness; thus, this study was aimed at revealing the possible role of spiritual outlooks as a protective factor in these individuals. The sample consisted of 96 Portuguese psychiatric patients, selected from a psychiatric hospital and assessed based on parameters for quality of life, spirituality and mindfulness. The data support some theories about the nature of the spirituality. Spiritual beliefs are poorly correlated with the quality of life index, and there is a moderate association between these beliefs and some aspects of mindfulness. It is suggested that a spiritual outlook of psychiatric patients should be taken into account in psychological interventions.     

Training kindergarten students lockdown drill procedures using behavioral skills training

During situations in which a gunman is present on a school campus, lockdowns are initiated until the threat is removed. However, there are no data demonstrating an effective teaching strategy to increase students’ correct responding during a lockdown. We evaluated the effectiveness of behavioral skills training (BST) to teach three groups of kindergarten students how to respond during lockdown drills. Results showed that participant groups displayed increases in correct steps and decreases in noise levels after BST was implemented; these effects maintained following training.     

The transfer of Crel contextual control (same,opposite, less than,more than) through equivalence relations

According to Relational Frame Theory (RFT) C_rel denotes a contextual stimulus that controls a particular type of relational response (sameness, opposition, comparative, temporal, hierarchical etc.) in a given situation. Previous studies suggest that contextual functions may be indirectly acquired via transfer of function. The present study investigated the transfer of C_rel contextual control through equivalence relations. Experiment 1 evaluated the transfer of C_rel contextual functions for relational responses based on sameness and opposition. Experiment 2 extended these findings by evaluating transfer of function using comparative C_rel stimuli. Both experiments followed a similar sequence of phases. First, abstract forms were established as C_rel stimuli via multiple exemplar training (Phase 1). The contextual cues were then applied to establish arbitrary relations among nonsense words and to test derived relations (Phase 2). After that, equivalence relations involving the original C_rel stimuli and other abstract forms were trained and tested (Phase 3). Transfer of function was evaluated by replacing the directly established C_rel stimuli with their equivalent stimuli in the former experimental tasks (Phases 1 and 2). Results from both experiments suggest that C_rel contextual control may be extended via equivalence relations, allowing other arbitrarily related stimuli to indirectly acquire C_rel functions and regulate behavior by evoking appropriate relational responses in the presence of both previously known and novel stimuli.     

Transgressing Motherhood: Media Reports on Infanticide

This article seeks to understand the discourses on motherhood elicited by media in news articles dealing with infanticide. Applying thematic analysis, we studied news and online comments of a Portuguese newspaper. The analysis of infanticidal mothers reports two different images of these mothers both constructed and profiled by the media and the readers. Women are more penalized based on their perversity, living in better economic conditions, being employed and married, whether by the media or by the readers. They are absolved in accordance with their mental illnesses or poor social and economic backgrounds.     

Factor structure and psychometric properties of the Brief Symptom Inventory-18 in women: a MACS approach to testing for invariance across racial/ethnic groups

This study used data from 3 sites to examine the invariance and psychometric characteristics of the Brief Symptom Inventory-18 across Black, Hispanic, and White mothers of 5th graders (N = 4,711; M = 38.07 years of age, SD = 7.16). Internal consistencies were satisfactory for all subscale scores of the instrument regardless of ethnic group membership. Mean and covariance structures analysis indicated that the hypothesized 3-factor structure of the instrument was not robust across ethnic groups. It provided a reasonable approximation to the data for Black and White women but not for Hispanic women. Tests for differential item functioning (DIF) were therefore conducted for only Black and White women. Analyses revealed no more than trivial instances of nonuniform DIF but more substantial evidence of uniform DIF for 3 of the 18 items. After having established partial strong factorial invariance of the instrument, latent factor means were found to be significantly higher for Black than for White women on all 3 subscales (somatization, depression, anxiety). In conclusion, the instrument may be used for mean comparisons between Black and White women.     

Perirhinal cortex is necessary for acquiring,but not for retrieving object–place paired association

Remembering events frequently involves associating objects and their associated locations in space, and it has been implicated that the areas associated with the hippocampus are important in this function. The current study examined the role of the perirhinal cortex in retrieving familiar object–place paired associates, as well as in acquiring novel ones. Rats were required to visit one of two locations of a radial-arm maze and choose one of the objects (from a pair of different toy objects) exclusively associated with a given arm. Excitotoxic lesions of the perirhinal cortex initially impaired the normal retrieval of object–place paired-associative memories that had been learned presurgically, but the animals relearned gradually to the level of controls. In contrast, when required to associate a novel pair of objects with the same locations of the maze, the same lesioned rats were severely impaired with minimal learning, if any, taking place throughout an extensive testing period. However, the lesioned rats were normal in discriminating two different objects presented in a fixed arm in the maze. The results suggest that the perirhinal cortex is indispensable to forming discrete representations for object–place paired associates. Its role, however, may be compensated for by other structures when familiar object–place paired associative memories need to be retrieved.Remembering an event in space often requires associating objects and their locations. Associating object and place information into a unitary event representation is believed to be a foundation of episodic memory (Cahusac et al. 1989; Gaffan 1994; Davachi 2006). It has been suggested that the hippocampus and its associated regions in the medial temporal lobe (MTL) are essential in this cognitive process, and amnesic patients with damage in the MTL structures exhibit severe deficits in associating object and place information (Smith and Milner 1981; Vargha-Khadem et al. 1997; Stepankova et al. 2004). Animal models produced by localized lesions in the hippocampus and other MTL structures also support the idea by showing that the lesioned animals are impaired in associating objects and places (Parkinson et al. 1988; Gaffan and Parker 1996; Sziklas et al. 1998; Bussey et al. 2001; Gilbert and Kesner 2003, 2004; Malkova and Mishkin 2003; Lee et al. 2005; Bachevalier and Nemanic 2008; Kesner et al. 2008; Lee and Solivan 2008). Although the theoretical importance of the MTL structures in object–place association has been well acknowledged, specific contributions of the MTL structures in object–place associative memory are poorly understood. The current study examined the role of the perirhinal cortex, one of the extra hippocampal regions in the MTL, using a behavioral paradigm previously shown to be dependent on the intact hippocampus (Lee and Solivan 2008).The literature suggests that the role of the hippocampus in the object–place paired-associate task is to put together object and place information into a unified and distinct event representation. It has been suggested that spatial information and nonspatial information (such as object information) may be streamed into the hippocampus in a relatively segregated fashion, the former information mostly fed through the medial entorhinal cortex to the hippocampus via the postrhinal cortex and the latter being fed through the lateral entorhinal cortex via the perirhinal cortex (Mishkin et al. 1997; Suzuki et al. 1997; Burwell 2000; Fyhn et al. 2004; Witter and Amaral 2004; Hafting et al. 2005; Hargreaves et al. 2005; Furtak et al. 2007; Kerr et al. 2007). In our previous study (Lee and Solivan 2008) in which rats were required to discriminate rewarding versus nonrewarding pairs of similar object–place paired associates, the hippocampal lesioned rats demonstrated severe and irrecoverable deficits. The results from the study not only corroborate the long-held view that the hippocampus associates object and place information, but also demonstrate that the hippocampus is critical for disambiguating similar object–place paired associates. However, it requires examining functions of other upstream structures of the hippocampus to conclusively assign the role of associating object and place information to the hippocampus. If, for example, lesions produced in the perirhinal cortex produce similar deficits, it would be premature to conclude that the association between object and place information uniquely occurs in the hippocampus.To elucidate the relative contributions of the MTL structures in the hippocampal-dependent object–place paired-associate task (Fig. 1), we manipulated the perirhinal cortex in the current study, one of the regions implicated as an object-information provider to the hippocampus (Knierim et al. 2006; Eichenbaum and Lipton 2008). Here we tested whether the perirhinal cortex was involved in the acquisition of new object–place paired associations. Importantly, we also tested the perirhinal cortical contributions to retrieving learned paired associates between objects and places. In the current study, the rats needed to pay attention to both object and place information. Therefore, if the perirhinal cortex is unique in its function for providing object information to the hippocampus, it is predicted that lesions in the perirhinal cortex will produce severe deficits as seen in the hippocampal lesioned animals in our previous study. A simple object-discrimination task that did not require spatial information was also employed to further examine the role of the perirhinal cortex only in specific conditions.Open in a separate windowFigure 1.Illustration of the radial arm maze and behavioral paradigms. (A) Phase 1: Two objects (Spider-Man and LEGO block) were presented on arms 3 and 5 in gray color. Only one of the objects was rewarded in arm 3 (Spider-Man) and arm 5 (LEGO block) irrespective of its locations in the choice platform. Possible configuration of objects and appropriate choices are provided for both arms. In each trial, only one arm was open in the maze and objects were available in that open arm. (B) Phase 2: For acquisition of novel object–place paired associations, a pair of new objects (Barney and Girl) was presented on arms 3 and 5. Possible locations of the objects are shown as in A. Each object was rewarded only in a particular arm (Barney in arm 3 and Girl in arm 5) irrespective of its location in the choice platform. (C) Phase 3: Illustration of the task using only one arm (arm 4) in the maze. Two new objects (Mr. Potatohead and Cylinder) were used and the Mr. Potatohead choice was rewarded regardless of its location in the choice platform.     

Expressions of emotional distress in active duty military personnel with mild traumatic brain injury: A qualitative content analysis

Service members (SMs) who sustain traumatic brain injury (TBI) during deployment have increased risk for mental health issues. Mental health treatment can be challenging in military settings where treatment seeking is often stigmatized. Adequate care relies on accurate interpretations of SMs’ verbal accounts of distress, but little is known about how SMs, embedded in a culture that values resilience and self-reliance, relay emotional distress. We performed qualitative analyses of recordings from a telephone-based intervention with 25 SMs who sustained deployment-related mild TBI (mTBI) to elucidate thematic and dialectal patterns. Consistent with our expectations, SMs rarely used explicit depressive terms while discussing their emotional distress. More prevalent was language suggestive of an overarching theme of loss of control, whereby SMs’ stress, anxiety, and anger were often attributable to SMs’ perceptions that they had incomplete jurisdiction over their own lives. This study may help mental health providers improve engagements with SMs and Veterans, preventing misunderstandings and even improper diagnoses or referrals that could result from a strict reliance on the more customary expressions of distress.     

A neurobehavioral investigation into judgmental processes: effect of bilateral motor behaviors

Two experiments were conducted in order to examine how different bilateral motor activations of the approach and avoidance motivational systems influenced participants' evaluations of valenced stimuli (figurative expressions and pictures of everyday situations). The first Study (Study 1) showed that participants judged valenced expressions according to the motor congruence model put forward by Cretenet and Dru (2004). This may depend on the compatibility of the valenced stimuli with the congruency of the bilateral motor behaviors that involved two unilateral motor behaviors that are congruent to each other. These results were duplicated in Study 2 with the use of valenced pictures taken from the International Affective Picture System. The overall results shed new light on the influence of motor behaviors on judgments, by determining the motor system as operative in evaluative mechanisms, and not merely a simple executive function of higher cognitive processes.     

Cluster randomized trials with treatment noncompliance

Cluster randomized trials (CRTs) have been widely used in field experiments treating a cluster of individuals as the unit of randomization. This study focused particularly on situations where CRTs are accompanied by a common complication, namely, treatment noncompliance or, more generally, intervention nonadherence. In CRTs, compliance may be related not only to individual characteristics but also to the environment of clusters individuals belong to. Therefore, analyses ignoring the connection between compliance and clustering may not provide valid results. Although randomized field experiments often suffer from both noncompliance and clustering of the data, these features have been studied as separate rather than concurrent problems. On the basis of Monte Carlo simulations, this study demonstrated how clustering and noncompliance may affect statistical inferences and how these two complications can be accounted for simultaneously. In particular, the effect of the intervention on individuals who not only were assigned to active intervention but also abided by this intervention assignment (complier average causal effect) was the focus. For estimation of intervention effects considering noncompliance and data clustering, an ML-EM estimation method was employed.
