Borderline and schizophrenic patients: A comparison using the MCMI-II

In the present study we examined the Millon Clinical Multiaxial Inventory-II scores of psychiatric patients with a diagnosis of either borderline personality disorder (BPD;n=13) or schizophrenia (n=13). The analyses revealed that the BPD patients were significantly elevated on a number of scales in addition to the Borderline scale. The second goal of this study was to assess the discriminative validity of the Borderline and Thought Disorder Scales with both base rate (BR) cutoffs and the number of endorsed prototypic items. The Borderline scale demonstrated the most diagnostic power when using BR cutoffs, whereas the Thought Disorder scale performed poorly, no better than chance levels, with all cutoffs.This research was supported by Social Sciences and Humanities Research Council of Canada Grant 410-89-0335 and by a grant from the Department of Research and Programme Evaluation, Brockville Psychiatric Hospital.

Psycholinguistics and education: Directions and divergences

The development of reading, foreign language competence, rhetorical and communicative skills, and symbolic thought processes differs from pure psycholinguistic research as horticulture differs from botany. Correspondences between educational psycholinguistics and pure psycholinguistics lie in how each views the learner on a continuum that ranges from docile to autonomous. Language can be characterized as arbitrary or derived from possible universal symbolizing processes, and curriculum in general can be characterized on a continuum ranging from opaque to emergent. Language acquisition can be viewed as the product of intentional socialization or an outgrowth of natural processes, and educators may be said to range from instructive to eductive in their approach to methods. The divergences between education and psycholinguistics in respect to their philosophical analysis of their research strategies and their views about individual variation and central tendencies seem to presage mutually supportive research programs.

Relationships between the Beck Depression Inventory and the Hamilton Psychiatric Rating Scale for Depression in depressed outpatients

The Beck Depression Inventory (BDI) and the Hamilton Psychiatric Rating Scale for Depression (HRSD) were used with 300 outpatients diagnosed with DSM-III major depression disorders. A principal-components analysis was performed on the intercorrelations among the 21 BDI and 24 HRSD symptoms. Three orthogonal components were found and interpreted as reflecting differences in self-report and clinical rating methods for measuring the severity of depression. The importance of using both self-reports and clinical ratings for evaluating depression in psychiatric outpatients was discussed.     

Extending the Balloon Analogue Risk Task to Assess Naturalistic Risk Taking via a Mobile Platform

The Balloon Analogue Risk Task (BART) is a behavioral measure that is commonly used to assess risk taking propensity. The primary goal of the present study was to introduce a mobile version of the BART (mBART) that can be included within ambulatory assessment protocols to assess risk taking in daily life. Study 1 compared common BART indices (i.e., total money earned, adjusted average pumps, balloon explosions, and coefficient of variability [CV]) on a single administration of the laboratory BART on a computer and the mBART on a smartphone (n = 78). Results revealed generally consistent relationships between indices of risk taking propensity in both the laboratory BART and mBART. Study 2 administered the mBART as part of a 7-day ecological momentary assessment (EMA) protocol in a population of nondaily smokers (n = 51). Using multi-level models, results suggest that males have greater adjusted average pumps (p = .03), and that a participant’s average CV is negatively related to trait sensation seeking (p = .03) and positively associated with trait positive urgency (p = .04). There were within-person effects of study day (p = .05) and environment (p = .02) with respect to adjusted average pumps such that individuals took greater risks as the study progressed and were riskier when alone compared to with others. Inclusion of the mBART in EMA did not appear to significantly increase participant burden and demonstrated acceptable levels of compliance. These results offer initial evidence supporting the feasibility and utility of the mBART for ambulatory research designs.     

Toddlers' context-varying emotions, maternal responses to emotions, and internalizing behaviors

Relations of toddlers' observed negative affect in high- and low-threat contexts to maternal perceptions of their toddlers' internalizing problems and to mothers' responses to emotions (RTE) for fear and sadness were examined. Child-driven, parent-driven, and reciprocal transactional models across 1 year were directly compared. Two-year-old toddlers (N = 106) participated in lab-based activities to elicit distress, and their negative affect was coded. Mothers completed measures of their child's internalizing behaviors and their responses to their toddler's fear and sadness at ages 2 and 3. At age 2, only negative affect in low-threat contexts was associated with greater internalizing problems. Mothers' punishing and minimizing RTE at age 2 predicted an increase in internalizing problems across 1 year. Age 2 internalizing problems predicted an increase in mother's use of supportive RTE over time. Results highlight the importance of considering the context of toddlers' negative affective displays and supported a reciprocal conceptualization of toddlers' internalizing behaviors and mothers' RTE.
