A systematic program to enhance clinician group skills in an inpatient psychiatric hospital

This article describes the collaborative effort of a team of discipline directors, administrators, and academicians to create a systematic program to enhance the group competencies of a large clinical staff working at a state hospital. The effects of the program were tested by a quasi-experimental field study. Quantitative measures of group process provided limited support for program effectiveness. Stronger support came from qualitative inquiry. The development and effectiveness of the program is examined within a larger context of group programs housed in large health care organizations.     

Impaired social functioning and symptoms of personality disorders assessed by peer and self-report in a nonclinical population

Data regarding the connection between personality disorders (PDs) and impaired social functioning are often difficult to interpret because both sets of variables are influenced by depressed mood and both are usually assessed using self-report instruments. We studied PD symptoms in a nonclinical population and examined whether these symptoms are associated with social dysfunction, after controlling for current mental state. Participants were 577 undergraduate students who completed self-report measures of social functioning, PD symptoms, depression, and anxiety, as well as a peer-report PD inventory. As expected, self-reported PD scores and social dysfunction were both correlated with current levels of anxiety and depression. Both self- and peer-reported PD symptoms contributed to the prediction of level of social functioning above and beyond the influence of depressed mood. Overall, our results complement those from clinical samples and provide further evidence that there is an association between PD traits and impaired social functioning.     

The Schedule for Nonadaptive and Adaptive Personality (SNAP): temporal stability and predictive validity of the diagnostic scales

The authors investigated the test-retest reliability and predictive validity of the diagnostic scales from the Schedule for Nonadaptive and Adaptive Personality (SNAP). Participants were identified from a sample of 240 undergraduates who completed the SNAP and the Social Adjustment Scale (SAS-SR) at Time 1. The authors selected 50 people who met criteria for a personality disorder (PD) based on the SNAP and 50 who did not qualify for a diagnosis. Eighty-three of these people completed the SNAP and the SAS-SR for a second time approximately 9 months after initial screening. SNAP PD scales were relatively stable over time. Test-retest correlation coefficients ranged from .58 to .81. Scores on diagnostic scales for paranoid, schizoid, and schizotypal PD were inversely related to self-reported levels of adjustment for social roles concerned with work as a student, leisure activities, and relationships with family. The results provide some evidence for the validity of the SNAP     

The reliability of the DRM paradigm as a measure of individual differences in false memories

Despite considerable research on the Deese—Roediger-McDermott (DRM) false memory paradigm, little attention has been paid to the reliability of the paradigm as a measure of individual differences. In the present research, we examined the reliability of the DRM paradigm in a 2-week test-retest design. This analysis showed that the false memories produced in the paradigm were quite stable across the 2-week period and that this stability had both global (cross-list) and list-specific components. In contrast, correct memories showed only global stability across the testing period.     

Age-related impairment in the 250-millisecond delay eyeblink classical conditioning procedure in C57BL/6 mice

In this study we tested 4-, 9-, 12-, and 18-month-old C57BL/6 mice in the 250-msec delay eyeblink classical conditioning procedure to study age-related changes in a form of associative learning. The short life expectancy of mice, complete knowledge about the mouse genome, and the availability of transgenic and knock-out mouse models of age-related impairments make the mouse an excellent species for expanding knowledge on the neurobiologically and behaviorally well-characterized eyeblink classical conditioning paradigm. Based on previous research with delay eyeblink conditioning in rabbits and humans, we predicted that mice would be impaired on this cerebellar-dependent associative learning task in middle-age, at ~9 months. To fully examine age differences in behavior in mice, we used a battery of additional behavioral measures with which to compare young and older mice. These behaviors included the acoustic startle response, prepulse inhibition, rotorod, and the Morris water maze. Mice began to show impairment in cerebellar-dependent tasks such as rotorod and eyeblink conditioning at 9 to 12 months of age. Performance in hippocampally dependent tasks was not impaired in any group, including 18-month-old mice. These results in mice support results in other species, indicating that cerebellar-dependent tasks show age-related deficits earlier in adulthood than do hippocampally dependent tasks.     

Sex and Age Differences in the Risk Threshold for Delinquency

This study examines sex differences in the risk threshold for adolescent delinquency. Analyses were based on longitudinal data from the Pittsburgh Youth Study (n?=?503) and the Pittsburgh Girls Study (n?=?856). The study identified risk factors, promotive factors, and accumulated levels of risks as predictors of delinquency and nondelinquency, respectively. The risk thresholds for boys and girls were established at two developmental stages (late childhood: ages 10–12 years, and adolescence: ages 13–16 years) and compared between boys and girls. Sex similarities as well as differences existed in risk and promotive factors for delinquency. ROC analyses revealed only small sex differences in delinquency thresholds, that varied by age. Accumulative risk level had a linear relationship with boys’ delinquency and a quadratic relationship with girls’ delinquency, indicating stronger effects for girls at higher levels of risk.     

Differentiation and infinitesimal relatives in peirce’s 1870 paper on logic: A new interpretation

The process of ‘logical differentiation’ was introduced by Peirce in 1870. Directly analogous to mathematical differentiation, it uses logical terms instead of mathematical variables. Here, this mysterious process receives new interpretations which serve to clarify Peirce’s use of logical terms. I introduce the logical terms, the operation of multiplication, the logical analogy to the binomial theorem, infinitesimal relatives, the concepts of numerical coefficients and the number associated with each term. I also analyse the algebraic development of ‘logical differentiation’ and consider in depth one application of the process     

A Case Study Exploring the Influence of a Gardening Therapy Group on Well-Being

In a climate of improving health-care quality and understanding, this study explored how participation in a gardening group, facilitated through a mental health service in Ireland, influenced well-being. A case study used semi-structured interviews and participant observation to explore explicit and tacit aspects of group participation. Thematic analysis clarified that gardening group participation had a positive influence on well-being for all gardeners and group facilitators. This was through promoting coping, facilitating change, and developing skills. The setting, site ethos and tasks were important in assisting people to make lifestyle changes and to develop skills in order to experience well-being.
