Ethnic differences in clinical presentation of depression in adult women

This study examined ethnic differences in self-report and interviewer-rated depressive symptoms and estimated the contributions of sociodemographic and psychosocial factors in predicting severity of depression. One hundred twenty-five clinically depressed African American (n = 46), Caucasian (n = 36), and Latina (n = 43) women were recruited. After controlling for differences in socioeconomic status, African American women reported more symptoms of distress and Latinas were rated as significantly more depressed than the other groups. However, these ethnic differences were not moderated by either education or employment. Finally, hierarchical regression analysis indicated that severity of depression was predicted by low education, being single, being Latina, high perceived stress, and feelings of hopelessness. Additional research is needed to validate these results and to investigate their clinical significance.     

Regulating the interpersonal self: strategic self-regulation for coping with rejection sensitivity

People high in rejection sensitivity (RS) anxiously expect rejection and are at risk for interpersonal and personal distress. Two studies examined the role of self-regulation through strategic attention deployment in moderating the link between RS and maladaptive outcomes. Self-regulation was assessed by the delay of gratification (DG) paradigm in childhood. In Study 1, preschoolers from the Stanford University community who participated in the DG paradigm were assessed 20 years later. Study 2 assessed low-income, minority middle school children on comparable measures. DG ability buffered high-RS people from interpersonal difficulties (aggression, peer rejection) and diminished well-being (e.g., low self-worth, higher drug use). The protective effect of DG ability on high-RS children's self-worth is explained by reduced interpersonal problems. Attentional mechanisms underlying the interaction between RS and strategic self-regulation are discussed.     

Procedural learning in schizophrenia: further consideration on the deleterious effect of neuroleptics

Deficits in procedural learning remain a controversial issue in schizophrenia. This may be related to the nature of the neuroleptic treatment of schizophrenic patients as conventional neuroleptics may be more deleterious than new atypical neuroleptics. However, there is no comparative study on the effect of specific neuroleptics on procedural learning. In this study, three groups of patients treated with different neuroleptics were compared to normal controls on two procedural learning tasks. In a visuo-motor task, patients and controls showed similar learning rates, although schizophrenic patients showed generally lower performances than normal controls. However, patients treated with a conventional neuroleptic, but not those treated with the atypical neuroleptics, showed many fluctuations during the initial learning phase. In a problem-solving task, all groups were comparable in performance and learning fluctuations, but learning rates were lower in patients treated with the neuroleptic showing the higher incidence of extrapyramidal symptoms. This suggests that procedural learning abilities may be significantly affected by neuroleptics in schizophrenia, although the effect may differ between tasks and the specific neuroleptics. Fluctuations in the initial learning phase of the visuo-motor task probably results from a frontal dysfunction while reduced learning rates, such as those observed in the problem solving task, may be attributed to a striatal dysfunction. This is concordant with the differential pharmacological actions of the conventional and atypical neuroleptics in these two cerebral areas.     

Family or friends: who plays a greater supportive role for Latino college students?

This study compared the relative contribution of perceived family and friend support to psychological well-being and distress and examined whether family or friend support moderated the effects of stress on psychological adjustment in 338 Latino (228 Mexican American, 110 Central American) college students from a predominantly Latino university. Two multiple regressions, controlling for gender, socioeconomic level, acculturation level, and stresses (generic college, acculturative, and minority status), showed that friend support made a slightly greater contribution to well-being than family support, and friend support and not family support protected against psychological distress. Neither family nor friend support moderated the effects of stress on psychological adjustment. Further examination of these variables that assess common-specific stresses within a culture-specific theoretical framework is recommended.     

Epidemiology of trauma and posttraumatic stress disorder in Mexico

Prevalence rates of trauma and posttraumatic stress disorder (PTSD) were estimated from a probability sample of 2,509 adults from 4 cities in Mexico. PTSD was assessed according to Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 1994) criteria using the Composite International Diagnostic Interview (CIDI; WHO, 1997). Lifetime prevalence of exposure and PTSD were 76% and 11.2%, respectively. Risk for PTSD was highest in Oaxaca (the poorest city), persons of lower socioeconomic status, and women. Conditional risk for PTSD was highest following sexual violence, but nonsexual violence and traumatic bereavement had greater overall impact because of their frequency. Of lifetime cases, 62% became chronic; only 42% received medical or professional care. The research demonstrates the importance of expanding the epidemiologic research base on trauma to include developing countries around the world.     

Cross-modal correlation of auditory and visual language laterality tasks: a serendipitous finding

Two experiments were conducted to investigate whether auditory and visual language laterality tasks test the same brain processes for verbal functions. In the first experiment, 48 undergraduate students (24 males, 24 females) completed both an auditory monitoring task and a visual monitoring task, with the Waterloo Handedness Questionnaire administered between the two tasks. The visual task was an analogue of the dichotic listening task used. It was hypothesized that a significant cross-modal correlation would be found, indicating that the dichotic listening task and the visual analogue task do, in fact, test the same brain processes for verbal functions. Results revealed a right ear advantage in the auditory task, a left visual field advantage (LVFA) in the visual task, and a cross-modal correlation of asymmetries of -.09. The LVFA observed in the visual task was replicated in Experiment 2, thus establishing its legitimacy. Results are discussed in relation with the type of processing that might produce such an unexpected finding on the visual task.     

A descriptive analysis of baseline and equivalence-class performances under many-to-one and one-to-many structures

The purpose of the present experiment was to describe responding as a function of One-to-Many (OTM) and Many-to-One (MTO) training structures and identify baseline performances correlated with the accuracy level in tests for equivalence class formation. Participants were 42 adults assigned to either the MTO or the OTM groups, trained on 24 baseline relations, and assessed on the emergence of three 9-member equivalence classes. Participants in the MTO group presented similar frequencies of responses to each of the comparisons throughout baseline training. Also, the number of trials required to meet the baseline mastery criterion was negatively correlated with test accuracy. Participants in the OTM group presented more variable frequencies of responses to each of the comparisons (participants tended to select some of the comparisons less often than others at the beginning of the training). In addition, the number of reinforced responses to the node presented as a sample during training was positively correlated with the number of correct responses during testing for the OTM group. The experiment contributed to an in-depth stimulus control analysis of baseline and test performances, and its results have implications for understanding potential sources of variability between the training structures.     

The effects of type of instruction,animacy cues,and dimensionality of objects on the shape bias in 3‐ to 6‐year‐old children

Robust evidence exists for the shape bias, or children's tendency to extend novel names and categorize objects more readily on the basis of shape than on other object features. However, issues remain about the conditions that affect the shape bias and its importance as a linguistic device. In this research, we examined how type of instruction (common noun naming, proper noun naming, same kind, and goes with), animacy of objects (animate, inanimate), and dimensionality of objects (two‐dimensional, three‐dimensional) affect the shape bias in 3‐ to 6‐year‐old children. Overall, all children showed strong use of the shape bias with categorization (same kind, goes with) instructions, the former in line with the shape‐as‐cue theory. Additionally, the shape bias was quite robust in the inanimate condition, regardless of type of instruction or dimensionality of objects. However, in the animate condition, a proper noun naming instruction coupled with an animate object cue reduced the shape bias across both two‐ and three‐dimensional objects. Implications of these findings are presented.

Highlights

• This study assessed the “shape bias,” a linguistic strategy young children routinely use when confronted with the task of extending a novel name from one object to another.
• Novel name extension and categorization tasks were used in this study.
• Shape bias was affected by the type of instructions, animacy of objects, and dimensionality of objects.

     

Clinical Supervision Dilemmas Related to Child Abuse in Wraparound Treatment

We conducted two separate, exploratory studies to evaluate the differences between the supervision of wraparound (in-home) and outpatient (office) child treatment interventions. Study one (n = 96) examined the structure and norms of supervision between groups as well as rates of general disclosure to direct supervisors. Study two (n = 116) specifically examined the frequency of child abuse and neglect encountered in each intervention setting, and the level of disclosure in supervision of these mandatory reporting events. Findings from the first study suggest that wraparound clinicians received significantly less individual supervision and colleague consultation than their office-based counterparts. Additionally, wraparound clinicians were significantly more likely to withhold information about client cases from their direct supervisors. In the second study, wraparound clinicians endorsed significant increases for observed child abuse, observed child neglect, and verbally reported child neglect compared to their office-based counterparts. In regards to mandatory reporting issues with children, wraparound clinicians were found to be significantly less likely to disclose issues pertaining to child neglect to their direct supervisors than office-based clinicians. Our studies show preliminary evidence for a needed increase of individual supervision in wraparound practice, in addition to a greater focus on clinician disclosures related to incidents of child abuse and neglect.     

Time perspective,socioeconomic status,and psychological distress in chronic pain patients

Time perspective (TP) is a fundamental dimension of the psychological construction of time. It refers to a subjective experience and can be defined as the relationship that individuals and groups have with the present, past, and future. Studies have shown that it is interesting to take into account TP in the field of health, especially for the study of the psychological distress (PD) of individuals faced with aversive situations. We conducted a research, which aimed to explore the relationship between TP and PD in patients with chronic pain. A total of 264 first-time patients (72.3% women; mean age = 49 years) at CHU Timone (Marseille) pain center answered a questionnaire included TP, socioeconomic status, pain beliefs (PB), pain characteristics, and sociodemographic characteristics. Using hierarchical regression analyses adjusted to the characteristics of pain, sociodemographic characteristics, and PB, we can observe significant relationships between different components of TP, socioeconomic status, and PD. These results emphasize the importance of TP as psychosocial variable in the analysis of PD in patients with chronic pain. These results also lead us to point out the role of the socioeconomic status that predicts levels of PD.
