Emotion regulation strategies in daily life: mindfulness, cognitive reappraisal and emotion suppression. - Cognitive behaviour therapy
Most empirical studies of emotion regulation have relied on retrospective trait measures, and have not examined the link between daily regulatory strategies and every day emotional well-being. We used a daily diary methodology with multilevel modelling data analyses (nÂ =Â 187) to examine the influence of three emotion regulation strategies (mindfulness, cognitive reappraisal and emotion suppression) on the experience of daily negative and positive affect. Our results suggested that daily mindfulness was associated with lower negative and higher positive affect whereas the converse pattern was found for daily emotion suppression; cognitive reappraisal was related to daily positive, but not negative affect. When daily mindfulness, suppression and reappraisal were included in the same models, these strategies predicted unique variance in emotional well-being. Random slope analyses revealed substantial variability in the utility of these strategies. Indeed the presumably "adaptive" cognitive reappraisal strategy seemed to confer no benefit to the regulation of negative affect in approximately half the sample. Additional analyses revealed that age moderates the effect of cognitive reappraisal on daily negative affect: Higher use of reappraisal was associated with more negative affect for adolescents (aged 17 to 19) but became associated with less negative affect with increasing age. We interpret these results in line with a contextual view of emotion regulation where no strategy is inherently "good" or "bad".
Schema modes in eating disorders compared to a community sample. - Journal of eating disorders
The aim of this study was to examine the association between eating disorders (ED) and schema modes, and identify which specific schema modes are associated with particular eating disorders, including anorexia nervosa (AN), bulimia nervosa (BN) and other specified feeding or eating disorder (OSFED).A total of forty seven women with eating disorders and 89 women from the community participated in this study. Eating disorder diagnosis was determined by a clinician treating the eating disorder and was confirmed on the basis of Body Mass Index (BMI) and the Eating Disorder Examination Questionnaire (EDE-Q). The Schema Mode Inventory (SMI) was used to explore the association between schema modes and eating disorder diagnostic status.A series t-tests revealed that when compared to the community sample, the ED group scored significantly higher on 10 out of 12 maladaptive schema modes, and significantly lower on both adaptive schema modes. A series of planned contrasts revealed that the AN, BN, and OSFED groups each scored significantly higher than the community sample group in the majority of maladaptive schema modes, with slight variations between groups. Further, AN, BN, and OSFED groups each scored significantly lower than the community sample group for the two SMI scores categorized as adaptive. All Cohen's d that reached significance ranged 0.55-2.24.The current study shows a tendency for females with eating disorders to rely on maladaptive schema modes more frequently, and more adaptive schema modes less frequently compared to a community sample. These findings provide initial empirical support for a schema mode model of eating disorders.
Psychometric Properties of Two Brief Versions of the Voices Acceptance and Action Scale (VAAS): Implications for the Second-wave and Third-wave Behavioural and Cognitive Approaches to Auditory Hallucinations. - Clinical psychology & psychotherapy
Despite a steep rise in the evidence base for third-wave cognitive and behavioural therapy approaches over the past decade, a scarcity of change measures relevant to these therapies as applied to psychosis is arguably slowing empirical progress in the area. The Voices Acceptance and Action Scale (VAAS), a measure of acceptance of voice experiences, is a notable exception. However, there are no published data on its psychometric properties outside of that provided by the scale developers. The current study explored the psychometric properties of two brief versions of the VAAS in a sample of psychotic voice hearers in a routine outpatient mental health service. Evidence from the current study suggests that both brief versions are robust measures of acceptance of voice experiences. Some limited support for the shortened VAAS-9 as being a marginally improved scale over the original brief VAAS-12 was also found. The current study found acceptance of voices to be highly related to depression, anxiety, stress and general negative affect and to predict unique variance in depression and general negative affect beyond that attributable to negative beliefs about voices and thought suppression. It was also found that acceptance was positively related to the use of reappraisal, indicating that the distinctiveness of acceptance from appraisal processes may be less pronounced in this context than what was has been reported previously. Implications for future research, as well as the practice of second-wave and third-wave cognitive and behavioural approaches to psychosis, are discussed.Two brief versions of the VAAS instrument were found to be robust measures of acceptance of psychotic voice experiences. The construct of acceptance of voices is highly related to indices of well-being and negative appraisal processes in psychosis and appears to offer an alternative route to therapeutically addressing the toxic effects of negative beliefs about voices. The recent focus on acceptance-based techniques within cognitive and behavioural approaches to psychosis was supported.Copyright Â© 2014 John Wiley & Sons, Ltd.
Spiral dynamics of pulsating methane-oxygen flames on a circular burner. - Chaos (Woodbury, N.Y.)
A premixed flame stabilized on a circular porous plug burner produces a uniform, steady luminous flame front. Throughout much of the parameter range hydrocarbon-oxygen mixtures form spiral-shaped fronts. In methane-oxygen flames at low pressure, the flame exhibits a sequence of states as a control parameter is decreased. These states include periodic rotation of a spiral front; precession of the spiral front in a direction opposite to its rotation, corresponding to doubly periodic petals-out meandering; and nonperiodic states with intermittent jumps associated with linear excursions of the tip, which occur after the spiral front has reached the boundary of the circular burner. We use Karhunen-Loeve (KL) analysis to find the coefficients of the dominant KL spatial eigenfunctions. Their phase space portraits and power spectra provide a description of the dynamics as flow rates are reduced and the system destabilizes. We discuss how these experimental results relate to previous theoretical studies that assume Euclidean symmetry for the experimental configuration.(c) 2004 American Institute of Physics
