Empowering self-critical perfectionistic students: A waitlist controlled feasibility trial of an explanatory feedback intervention on daily coping processes.

This study of 176 university students tested a single-session explanatory feedback intervention (EFI), derived from the perfectionism coping processes model. Participants with higher self-critical perfectionism completed daily measures of stress appraisals, coping, and affect for 7 days. A randomized control design was used to compare an EFI condition with a waitlist control condition over 4 weeks with individualized feedback delivered one-on-one by student trainees in-person or remotely through videoconferencing. The feasibility of the individualized analyses of each participant's daily data was supported by identifying daily trigger patterns, maintenance tendencies, strengths, common triggers, and best targets for reducing negative mood and increasing positive mood across several stressors for each participant. Participant ratings indicated that the comprehensive feedback was coherent and functional. Participants in the EFI condition, compared to those in the control condition, reported increases in empowerment, coping self-efficacy, and problem-focused coping, as well as decreases in depressive and anxious symptoms. Between-group effect sizes were moderate-to-large. There were reliable improvements in empowerment and depressive symptoms for 56% and 36%, respectively, of participants in the EFI condition. These findings demonstrate the broad applicability, conceptual utility, and effectiveness of the EFI for self-critical perfectionistic individuals.

Emotional and interpersonal mechanisms in community SSRI treatment of social anxiety disorder.

BACKGROUND: Affective and interpersonal behavioural patterns characteristic of social anxiety disorder show improvement during treatment with serotonin agonists (e.g., selective serotonin reuptake inhibitors), commonly used in the treatment of social anxiety disorder. The present study sought to establish whether, during community psychopharmacological treatment of social anxiety disorder, changes in positive or negative affect and agreeable or quarrelsome behaviour mediate improvement in social anxiety symptom severity or follow from it. METHODS: Adults diagnosed with social anxiety disorder (n = 48) recorded their interpersonal behaviour and affect naturalistically in an event-contingent recording procedure for 1-week periods before and during the first 4 months of treatment with paroxetine. Participants and treating psychiatrists assessed the severity of social anxiety symptoms monthly. A multivariate latent change score framework examined temporally lagged associations of change in affect and interpersonal behaviour with change in social anxiety symptom severity. RESULTS: Elevated agreeable behaviour and positive affect predicted greater subsequent reduction in social anxiety symptom severity over the following month of treatment. Elevated negative affect, but not quarrelsome behaviour, predicted less subsequent reduction in symptom severity. LIMITATIONS: Limitations included limited assessment of extreme behaviour (e.g., violence) that may have precluded examining the efficacy of paroxetine because of the lack of a placebo control group. CONCLUSION: The present study suggests that interpersonal behaviour and affect may be putative mechanisms of action for serotonergic treatment of social anxiety disorder. Prosocial behaviour and positive affect increase during serotonergic treatment of social anxiety disorder. Specifically, modulating agreeable behaviour, positive affect and negative affect in individuals' daily lives may partially explain and refine clinical intervention.

Implementation of Bar-Code Medication Administration to Reduce Patient Harm.

OBJECTIVE: To assess the impact of implementing bar-code medication administration (BCMA) technology on the rate of medication administration errors in the inpatient setting, specifically those that affect the patient and result in harm. PATIENTS AND METHODS: Implementation of the new technology began in September 2008 in a staged rollout of 4 or 5 units at a time in 11 separate waves. All corresponding medication administrations and voluntarily reported medication-related adverse events from March 1, 2007, through September 30, 2013, were included for analyses. Adherence to the use of BCMA technology and the number of adverse events were tracked and compared across the preimplementation period through follow-up. Actual errors, not potential errors, were included in the analysis. RESULTS: After the BCMA technology was introduced, reported medication administration errors decreased by 43.5%. More importantly, the rate of harmful medication errors decreased from 0.65 per 100,000 medications preintervention to 0.29 per 100,000 medications postintervention. This resulted in a 55.4% decrease in actual patient harm events. None of the errors at category E or higher was caused by BCMA factors. CONCLUSION: Consistent use of BCMA technology improves patient safety by decreasing the number of patients harmed by medication administration errors.

Affect, interpersonal behaviour and interpersonal perception during open-label, uncontrolled paroxetine treatment of people with social anxiety disorder: a pilot study

Background: Laboratory-based research with community samples has suggested changes in affective, behavioural and cognitive processes as possible explanations for the effects of serotonergic medications. Examining the effects of serotonergic medications using an ecological momentary measure (such as event-contingent recording) in the daily lives of people with social anxiety disorder would contribute to establishing the effects of these medications on affect, behaviour and one form of cognition: perception of others' behaviour. Methods: The present study assessed changes in affect, interpersonal behaviour and perception of others' behaviour in adults with social anxiety disorder using ecological momentary assessment at baseline and over 4 months of a single-arm, uncontrolled, open-label trial of treatment with the selective serotonin reuptake inhibitor paroxetine. Results: Anxiety and concurrent depressive symptoms decreased. Participants also reported increased positive and decreased negative affect; increased agreeable and decreased quarrelsome behaviour; increased dominant and decreased submissive behaviour; and increased perception that others behaved agreeably toward them. Moreover, participants demonstrated reduced intraindividual variability in affect, interpersonal behaviour and perception of others' behaviour. Limitations: Limitations included the lack of a placebo group, the inability to identify the temporal order of changes and the restricted assessment of extreme behaviour. Conclusion: The results of the present study demonstrate changes during pharmacotherapy in the manifestation of affect, interpersonal behaviour and interpersonal perception in the daily lives of people with social anxiety disorder. Given the importance of interpersonal processes to social anxiety disorder, these results may guide future research seeking to clarify mechanisms of action for serotonergic medications.

Allostatic load and comorbidities: A mitochondrial, epigenetic, and evolutionary perspective.

Stress-related pathophysiology drives comorbid trajectories that elude precise prediction. Allostatic load algorithms that quantify biological "wear and tear" represent a comprehensive approach to detect multisystemic disease processes of the mind and body. However, the multiple morbidities directly or indirectly related to stress physiology remain enigmatic. Our aim in this article is to propose that biological comorbidities represent discrete pathophysiological processes captured by measuring allostatic load. This has applications in research and clinical settings to predict physical and psychiatric comorbidities alike. The reader will be introduced to the concepts of allostasis, allostasic states, allostatic load, and allostatic overload as they relate to stress-related diseases and the proposed prediction of biological comorbidities that extend rather to understanding psychopathologies. In our transdisciplinary discussion, we will integrate perspectives related to (a) mitochondrial biology as a key player in the allostatic load time course toward diseases that "get under the skin and skull"; (b) epigenetics related to child maltreatment and biological embedding that shapes stress perception throughout lifespan development; and

Impact of personality psychopathology on outcome in short-term cognitive-behavioral therapy for Axis I disorders.

Cognitive behavioral therapy (CBT) is efficacious for many Axis I disorders, though its effectiveness in the real world, for patients with Axis II comorbidity is less well known. This study examines the effectiveness of CBT for Axis I disorders in three groups of patients: those with personality disorders, those with personality disorder traits and those with no Axis II pathology. Consecutive referrals of patients with non-psychotic Axis I disorders were assessed for short-term CBT in a University Teaching Unit. While the acceptance rate was lower for individuals with personality disorders, there were no group differences in dropout rates. Of those who completed therapy (mean number of sessions=17.8, SD=11.2), those in the Personality Disorders group (n=45) had 4 sessions more on average than the Personality Disorder Traits group (n=42) or the No Axis II Group (n=266). All 3 groups were equally successful, whether the outcome was therapist opinion of success, the clinical global impression, or the reliable change index based on patient-reported symptom change. Intent to treat analysis results paralleled those of the completer analysis. Our findings indicate that the presence of a personality disorder does not negatively impact therapy adherence or success in short-term CBT for an Axis I disorder.

Predicting who benefits most from cognitive-behavioral therapy for anxiety and depression.

OBJECTIVES: We examined core features of patient suitability for cognitive-behavioral therapy (CBT) and their ability to predict CBT outcomes. METHOD: A sample of 256 outpatients diagnosed with depression and anxiety disorders were assessed using the Suitability for Short-Term Cognitive Therapy (SSCT) scale. Therapists rated patients' symptom severity using the Clinical Global Impression scale before and after therapy. RESULTS: A factor analysis of the SSCT scale yielded 2 factors: (a) Capacity for Participation in CBT Process and (b) Attitudes Relevant to the CBT Process. A multiple regression analysis revealed that only Capacity for Participation in CBT Process uniquely predicted improvement at termination. CONCLUSIONS: These findings highlight the importance of assessing the suitability of CBT for individual patients. Specifically, patients with greater capacity to identify and articulate thoughts and feelings and to share them in a nondefensive, focused way benefit most from CBT.

Understanding heterogeneity in social anxiety disorder: dependency and self-criticism moderate fear responses to interpersonal cues.

OBJECTIVE: This study examined how the personality traits of self-criticism and dependency moderated the effects of situational interpersonal cues on fear during interpersonal interactions among individuals with social anxiety disorder (SAD). We hypothesized that self-criticism would moderate the fear-inducing effects of situational self-consciousness and that dependency would moderate the fear-inducing effects of situational emotional insecurity. METHODS: Forty SAD patients (Mage = 29.23) and matched community controls (Mage = 28.93) completed event-contingent record forms after each significant social interaction of over 5 min for a 20-day period. There were 20 female patients and 20 male patients in each group. RESULTS: Event-level self-consciousness was more strongly associated with elevations in fear among socially anxious patients who reported higher levels of self-criticism, while event-level emotional security was more strongly associated with decreases in fear among SAD patients who reported higher levels of dependency. These interactions were not found in the community sample. CONCLUSIONS: Findings support the application of personality-vulnerability models to understanding fear during social interactions in patients with SAD. Results also have implications for psychotherapeutic treatments of SAD.

The association between positive outcome expectancies and avoidance in predicting the outcome of cognitive behavioural therapy for major depressive disorder.

OBJECTIVES: Although cognitive behavioural therapy (CBT) is an empirically supported treatment for major depressive disorder (MDD), individual differences in the effectiveness of CBT have been observed. Preliminary evidence suggests that positive outcome expectancies for treatment predict better therapy outcomes (Constantino, Arnkoff, Glass, & Smith, 2011); however, researchers have not examined whether avoidance, an important predictor of depressive symptoms (Ottenbreit & Dobson, 2004), may play an important role in this association. In the present study, we examined whether the association between positive outcome expectancies and therapy outcome is associated with patients' levels of avoidance. DESIGN: Data were collected as part of a prospective, longitudinal study. METHODS: The sample consisted of 51 patients diagnosed with MDD who underwent CBT. Prior to treatment, clinicians rated patients on their levels of avoidance and positive outcome expectancies. A self-report rating of positive outcome expectancies was also obtained, and the Beck Depression Inventory (BDI-II; Beck, Steer, & Brown, 1996) was completed pre- and post-treatment. A hierarchical regression analysis was conducted to examine the association between positive outcome expectancies and avoidance for predicting changes in depressive symptoms after CBT. RESULTS: For patients with lower levels of positive outcome expectancies, lower levels of avoidance predicted greater improvement after CBT and higher levels of avoidance predicted poorer treatment outcomes. CONCLUSIONS: These findings suggest that the impact that lower positive outcome expectancies have on therapy outcome can be attenuated if patients do not avoid dealing with emotionally difficult material in session.

Assessing suitability for short-term cognitive-behavioral therapy in psychiatric outpatients with psychosis: a comparison with depressed and anxious outpatients.

OBJECTIVE: The Suitability for Short-Term Cognitive Therapy (SSCT) rating procedure has predicted outcome in depressed and anxious patients. This study examines its relevance in assessing patients with psychosis. METHOD: Outpatients with psychosis (n=56), depression (n=93), and anxiety (n=264) received cognitive- behavioral therapy in a university hospital teaching unit (mean number of sessions=16, SD=11). Demographic, clinical, and suitability variables were assessed as potential predictors of dropout and success as measured by the Reliable Change Index. RESULTS: Despite lower suitability scores in the psychosis group, dropout and success rates were similar across groups, although the magnitude of symptom reduction was less in the psychosis group. Across diagnoses, dropout was predicted by unemployment and by reluctance to take personal responsibility for change. In the psychosis group only, dropout was predicted by hostility. Success of completed therapy was predicted by higher baseline agoraphobic anxiety and "responsibility for change" scores. CONCLUSION: Attention to hostility early in therapy may reduce dropout in psychotic patients. Fostering acceptance of responsibility for change may improve both treatment retention and success across diagnoses. Agoraphobic fear is associated with success, possibly reflecting the effectiveness of behavioral interventions in psychosis and anxiety alike.

Quarrelsome behavior in borderline personality disorder: influence of behavioral and affective reactivity to perceptions of others.

We examined how the amplification of 3 within-person processes (behavioral reactivity to interpersonal perceptions, affect reactivity to interpersonal perceptions, and behavioral reactivity to a person's own affect) accounts for greater quarrelsome behavior among individuals with borderline personality disorder (BPD). Using an event-contingent recording (ECR) methodology, individuals with BPD (N = 38) and community controls (N = 31) reported on their negative affect, quarrelsome behavior, and perceptions of the interaction partner's agreeable-quarrelsome behavior in interpersonal events during a 20-day period. Behavioral reactivity to negative affect was similar in both groups. However, behavioral reactivity and affect reactivity to interpersonal perceptions were elevated in individuals with BPD relative to community controls; specifically, individuals with BPD reported more quarrelsome behavior and more negative affect during interactions in which they perceived others as more cold-quarrelsome. Greater negative affect reactivity to perceptions of other's cold-quarrelsome behavior partly accounted for the increased quarrelsome behavior reported by individuals with BPD during these interactions. This pattern of results suggests a cycle in which the perception of cold-quarrelsome behavior in others triggers elevated negative affect and quarrelsome behavior in individuals with BPD, which subsequently led to more quarrelsome behavior from their interaction partners, which leads to perceptions of others as cold-quarrelsomeness, which begins the cycle anew.

Understanding heterogeneity in borderline personality disorder: differences in affective reactivity explained by the traits of dependency and self-criticism.

This study examined whether the personality traits of self-criticism and dependency respectively moderated the effects of perceived inferiority and emotional insecurity on negative affect during interpersonal interactions in individuals with borderline personality disorder (BPD). A sample of 38 patients with BPD and matched community comparison participants completed event-contingent record forms after each significant interaction for a 20-day period. Multilevel models showed that, controlling for baseline levels of depressive symptoms and neuroticism, as well as lagged negative affect, event-level elevations in perceived inferiority and emotional insecurity were related to more negative affect in both groups. Event-level perceived inferiority was more strongly associated with negative affect in patients with BPD who reported higher levels of self-criticism, while event-level perceived emotional insecurity was more strongly associated with negative affect in patients with BPD who reported higher levels of dependency. No significant interactions emerged for the comparison group. These findings further our understanding of differences among patients with BPD and support the application of personality-vulnerability or diathesis-stress models in predicting negative affect in BPD. Results have implications for the design of therapies for patients with BPD.

Affect dysregulation in individuals with borderline personality disorder: persistence and interpersonal triggers.

We hypothesized that affect dysregulation among individuals with borderline personality disorder (BPD) would involve greater persistence of negative affect between interpersonal events and heightened reactivity to stimuli indicating risk of rejection or disapproval, specifically perceptions of others' communal (agreeable-quarrelsome) behaviors. A total of 38 participants with BPD and 31 controls collected information about affect and perceptions of the interaction partner's behavior during interpersonal events for a 20-day period. Negative and positive affect persisted more across interpersonal events for individuals with BPD than for controls. In addition, individuals with BPD reported a greater increase in negative affect when they perceived less communal behavior and a smaller increase in positive affect when they perceived more communal behavior in others. Findings indicate the importance of interpersonal perceptions in the affect dysregulation of individuals with BPD.

Synthesis and properties of Zn-Mg heterobimetallic carbamates. Crystal structures of the first reported single source precursors for Zn(x)mg(1-x)O thin films.

The first mixed-metal Zn-Mg carbamates have been synthesised using a novel strategy of co-reaction between zinc and magnesium alkylamido intermediates. The complexes were structurally characterised by single-crystal X-ray diffraction; the nuclearity of these carbamato core subunits was found to vary from tetrameric to octameric with respect to the level of magnesium incorporated. The presence of magnesium in the predominantly zinc carbamato lattice was confirmed by refinement of the site occupancies of the metal atoms during the crystal data analysis, and it was found that displacement of up to 7.8% of zinc sites by magnesium atoms could be achieved before breakdown of the structure. Characterisation of the complexes' physicochemical properties revealed that they were suitable for use as single-source chemical vapour deposition (SSCVD) precursors in the deposition of Zn(x)Mg(1-x)O thin films, an emerging material with promising band-gap engineering prospects.

Alcohol in a social context: findings from event-contingent recording studies of everyday social interactions.

BACKGROUND: Data concerning the effects of alcohol on social interaction in everyday life are limited. METHODS: Healthy volunteers in 4 studies of social behaviors and mood were instructed to complete record forms immediately after a social interaction had occurred, a method known as event-contingent recording. Record forms asked questions about quarrelsome, agreeable, dominant, and submissive behaviors; about aspects of mood; and, in 3 studies, about perceptions of others. Each form also contained a question about alcohol consumption prior to a social interaction. For the present report, only social interactions taking place in the evening and outside the work setting were included. Only individuals who consumed alcohol at least once in these circumstances were included (n = 171). RESULTS: Social interactions involving alcohol were primarily characterized by higher levels of agreeable behaviors, by perceptions of greater agreeableness in others, and by more positive mood. Alcohol consumption was not associated with higher levels of quarrelsomeness. CONCLUSIONS: Alcohol consumption in a social context may have predominantly positive effects, an observation which is at odds with most alcohol-induced aggression experiments performed in laboratory settings. Drinking in everyday life may be less likely to result in aggression because, unlike in most laboratory experiments, individuals can choose among a variety of behaviors in response to social cues and the alcohol dose consumed is usually lower. Event-contingent recording provides a new approach for the study of alcohol's effects in everyday life and the conditions in which alcohol might result in interpersonal aggression.

Stability and variability of affective experience and interpersonal behavior in borderline personality disorder.

This study examined both mean levels and intraindividual variability in the mood and interpersonal behavior of individuals with borderline personality disorder (BPD) and nonclinical control participants over a 20-day event-contingent recording period. Individuals in the BPD group experienced more unpleasantly valenced affect and were less dominant, more submissive, more quarrelsome, and more extreme in overall levels of behavior than control participants. In addition to these mean-level differences, individuals with BPD also reported more intraindividual variability in overall affect valence and in pleasantly valenced affect; displayed greater variability in dominant, quarrelsome, and agreeable behaviors; and exhibited an increased tendency to "spin" among interpersonal behaviors relative to nonclinical control participants. The findings document behavioral and affective manifestations of BPD in the context of naturally occurring interpersonal situations.

Growth mechanism of textured MgO thin films via SSCVD.

Magnesium oxide thin films have been deposited with use of single source chemical vapor deposition (SSCVD). The resultant films were examined by using transmission electron microscopy, X-ray texture analysis, and pole figure analysis. Due to the nature of the chemical reactions occurring at the surface during SSCVD growth, which result in a high growth rate/low flux environment, films of (111) orientation have been achieved without an amorphous underlayer, an unusual result for films of this orientation. Moreover the films have a strong degree of biaxial texturing in the x-y plane as found with X-ray texture analysis. These findings have important implications for buffer layers in perovskite thin film devices. The mechanism producing these structures has been revealed by using TEM and is discussed here.

Effects of dairy products naturally enriched with cis-9,trans-11 conjugated linoleic acid on the blood lipid profile in healthy middle-aged men.

BACKGROUND: Interest in the development of dairy products naturally enriched in conjugated linoleic acid (CLA) exists. However, feeding regimens that enhance the CLA content of milk also increase concentrations of trans-18:1 fatty acids. The implications for human health are not yet known. OBJECTIVE: This study investigated the effects of consuming dairy products naturally enriched in cis-9,trans-11 CLA (and trans-11 18:1) on the blood lipid profile, the atherogenicity of LDL, and markers of inflammation and insulin resistance in healthy middle-aged men. DESIGN: Healthy middle-aged men (n = 32) consumed ultra-heat-treated milk, butter, and cheese that provided 0.151 g/d (control) or 1.421 g/d (modified) cis-9,trans-11 CLA for 6 wk. This was followed by a 7-wk washout and a crossover to the other treatment. RESULTS: Consumption of dairy products enriched with cis-9,trans-11 CLA and trans-11 18:1 did not significantly affect body weight, inflammatory markers, insulin, glucose, triacylglycerols, or total, LDL, and HDL cholesterol but resulted in a small increase in the ratio of LDL to HDL cholesterol. The modified dairy products changed LDL fatty acid composition but had no significant effect on LDL particle size or the susceptibility of LDL to oxidation. Overall, increased consumption of full-fat dairy products and naturally derived trans fatty acids did not cause significant changes in cardiovascular disease risk variables, as may be expected on the basis of current health recommendations. CONCLUSION: Dairy products naturally enriched with cis-9,trans-11 CLA and trans-11 18:1 do not appear to have a significant effect on the blood lipid profile.

Incorporation of cis-9, trans-11 conjugated linoleic acid and vaccenic acid (trans-11 18 : 1) into plasma and leucocyte lipids in healthy men consuming dairy products naturally enriched in these fatty acids.

The present study investigated whether consuming dairy products naturally enriched in cis-9, trans-11 (c9,t11) conjugated linoleic acid (CLA) by modification of cattle feed increases the concentration of this isomer in plasma and cellular lipids in healthy men. The study had a double-blind cross-over design. Subjects aged 34-60 years consumed dairy products available from food retailers for 1 week and then either control (0.17 g c9,t11 CLA/d; 0.31 g trans-vaccenic acid (tVA)/d) or CLA-enriched (1.43 g c9,t11 CLA/d; 4.71 g tVA/d) dairy products for 6 weeks. After 7 weeks washout, this was repeated with the alternate products. c9,t11 CLA concentration in plasma lipids was lower after consuming the control products, which may reflect the two-fold greater c9,t11 CLA content of the commercial products. Consuming the CLA-enriched dairy products increased the c9,t11 CLA concentration in plasma phosphatidylcholine (PC) (38 %; P = 0.035), triacylglycerol (TAG) (22 %; P < 0.0001) and cholesteryl esters (205 %; P < 0.0001), and in peripheral blood mononuclear cells (PBMC) (238 %; P < 0.0001), while tVA concentration was greater in plasma PC (65 %; P = 0.035), TAG (98 %; P = 0.001) and PBMC (84 %; P = 0.004). Overall, the present study shows that consumption of naturally enriched dairy products in amounts similar to habitual intakes of these foods increased the c9,t11 CLA content of plasma and cellular lipids.

Effects of cis-9,trans-11 and trans-10,cis-12 conjugated linoleic acid on immune cell function in healthy humans.

BACKGROUND: Animal studies have suggested that conjugated linoleic acid (CLA), a natural component of ruminant meat and dairy products, may confer beneficial effects on health. However, little information on the effects of CLA on immune function is available, especially in humans. Furthermore, the effects of individual isomers of CLA have not been adequately investigated. OBJECTIVE: This study investigated the effects of supplementing the diet with 3 doses of highly enriched cis-9,trans-11 CLA (0.59, 1.19, and 2.38 g/d) or trans-10,cis-12 CLA (0.63, 1.26, and 2.52 g/d) on immune outcomes in healthy humans. DESIGN: The study had a randomized, double-blind, crossover design. Healthy men consumed 1, 2, and 4 capsules sequentially that contained 80% of either cis-9,trans-11 CLA or trans-10,cis-12 CLA for consecutive 8-wk periods. This regimen was followed by a 6-wk washout and a crossover to the other isomer. RESULTS: Both CLA isomers decreased mitogen-induced T lymphocyte activation in a dose-dependent manner. There was a significant negative correlation between mitogen-induced T lymphocyte activation and the proportions of both cis-9,trans-11 CLA and trans-10,cis-12 CLA in peripheral blood mononuclear cell lipids. However, CLA did not affect lymphocyte subpopulations or serum concentrations of C-reactive protein and did not have any consistent effects on ex vivo cytokine production. CONCLUSION: CLA supplementation results in a dose-dependent reduction in the mitogen-induced activation of T lymphocytes. The effects of cis-9,trans-11 CLA and trans-10,cis-12 CLA were similar, and there was a negative correlation between mitogen-induced T lymphocyte activation and the cis-9,trans-11 CLA and trans-10,cis-12 CLA contents of mononuclear cells.
