An Internet-Based Compassion-Focused Intervention for Increased Self-Criticism: A Randomized Controlled Trial

Increased levels of self-criticism and a lack of self-compassion have been associated with the development and maintenance of a range of psychological disorders. In the current study, we tested the efficacy of an online version of a compassion-focused intervention, mindfulness-based compassionate living (MBCL), with guidance on request. A total of 122 self-referred participants with increased levels of self-criticism were randomly assigned to care as usual (CAU) or the intervention group (CAU + online intervention). Primary endpoints were self-reported depressive, anxiety and distress symptoms (DASS-21) and self-compassion (SCS) at 8 weeks. Secondary endpoints were self-criticism, mindfulness, satisfaction with life, fear of self-compassion, self-esteem, and existential shame. At posttreatment, the intervention group showed significant changes with medium to large effect sizes compared to the control group regarding primary outcomes (Cohen’s d: 0.79 [DASS] and -1.21 [SCS]) and secondary outcomes (Cohen’s ds: between 0.40 and 0.94 in favor of the intervention group). The effects in the intervention group were maintained at 6-months postrandomization. Adherence measures (number of completed modules, self-reported number of completed exercises per week) predicted postintervention scores for self-compassion but not for depressive, anxiety, and distress symptoms in the intervention group. The current study shows the efficacy of an online intervention with a transdiagnostic intervention target on a broad range of measures, including depressive and anxiety symptoms and self-compassion.     

Neural correlates of adaptive decision making for risky gains and losses

Do decisions about potential gains and potential losses require different neural structures for advantageous choices? In a lesion study, we used a new measure of adaptive decision making under risk to examine whether damage to neural structures subserving emotion affects an individual's ability to make adaptive decisions differentially for gains and losses. We found that individuals with lesions to the amygdala, an area responsible for processing emotional responses, displayed impaired decision making when considering potential gains, but not when considering potential losses. In contrast, patients with damage to the ventromedial prefrontal cortex, an area responsible for integrating cognitive and emotional information, showed deficits in both domains. We argue that this dissociation provides evidence that adaptive decision making for risks involving potential losses may be more difficult to disrupt than adaptive decision making for risks involving potential gains. This research further demonstrates the role of emotion in decision competence.     

Learning and memory deficits in mice lacking protease activated receptor-1

The roles of serine proteases and protease activated receptors have been extensively studied in coagulation, wound healing, inflammation, and neurodegeneration. More recently, serine proteases have been suggested to influence synaptic plasticity. In this context, we examined the role of protease activated receptor 1 (PAR1), which is activated following proteolytic cleavage by thrombin and plasmin, in emotionally motivated learning. We were particularly interested in PAR1 because its activation enhances the function of NMDA receptors, which are required for some forms of synaptic plasticity. We examined several baseline behavioral measures, including locomotor activity, expression of anxiety-like behavior, motor task acquisition, nociceptive responses, and startle responses in C57Bl/6 mice in which the PAR1 receptor has been genetically deleted. In addition, we evaluated learning and memory in these mice using two memory tasks, passive avoidance and cued fear-conditioning. Whereas locomotion, pain response, startle, and measures of baseline anxiety were largely unaffected by PAR1 removal, PAR1-/- animals showed significant deficits in a passive avoidance task and in cued fear conditioning. These data suggest that PAR1 may play an important role in emotionally motivated learning.     

Assessing the Structural and Psychometric Properties of a New Personality Measure for Use With Military Personnel in the French Armed Forces

We evaluated the measurement properties of a new personality scale for use with military personnel in the French Navy (N = 1,266). Principal components analyses indicated a five-factor structure assessing emotional stability, ascendancy, openness, agreeableness, and conscientiousness. Each factor comprised two facets that included 7 items per facet for a total of 70 items. Reliability analyses indicate that the factors and corresponding facets were internally consistent and temporally stable. Validity analyses indicate that the TAMI-P was significantly correlated with comparable measures of personality—correlations ranged from .53 to .68 with the Revised NEO Personality Inventory and the Big Five Questionnaire.     

Level of emotional awareness in the general French population: Effects of gender,age, and education level

The Levels of Emotional Awareness Scale (LEAS) developed by Lane et al. ( 1990 1990) measures the ability of a subject to discriminate his or her own emotional state and that of others. The scale is based on a cognitive‐developmental model in which emotional awareness increases in a similar fashion to intellectual functions. Because studies performed using North American and German populations have demonstrated an effect of age, gender, and level of education on the ability to differentiate emotional states, our study attempts to evaluate whether these factors have the same effects in a general French population. 750 volunteers (506 female, 244 male), who were recruited from three regions of France (Lille, Montpellier, Paris), completed the LEAS. The sample was divided into five age groups and three education levels. The results of the LEAS scores for self and others and the total score showed a difference in the level of emotional awareness for different age groups, by gender and education level. A higher emotional level was observed for younger age groups, suggesting that emotional awareness depends on the cultural context and generational societal teachings. Additionally, the level of emotional awareness was higher in women than in men and lower in individuals with less education. This result might be explained by an educational bias linked to gender and higher education whereby expressive ability is reinforced. In addition, given the high degree of variability in previously observed scores in the French population, we propose a standard based on our French sample.     

Chunking by colors: assessing discrete learning in a continuous serial reaction-time task

Chunk learning (the process by which a sequence is learned and retrieved from memory in smaller, decomposed units of information) has been postulated as the main learning mechanism underlying sequence learning (Perruchet & Pacton, 2006). However, the evidence for chunk formation has been elusive in the continuous serial reaction-time task, whereas other continuous, statistical processes of learning account well for the results observed in this task. This article proposes a new index to capture segmentation in learning, based on the variance of responding to different parts of a sequence. We assess the validity of this measure by comparing performance in a control group with that of another group in which color codes were used to induce a uniform segmentation. Results showed that evidence of chunking was obtained when the color codes were consistently coupled to responses, but that chunking was not maintained after the colors were removed.     

Genetic testing for hereditary cancer: effects of alexithymia and coping strategies on variations in anxiety before and after result disclosure

This study assessed the impact of the results of genetic testing for hereditary cancer from a multifactorial health psychology perspective, considering that emotional expression plays a key role in psychological adjustment. Measures of dispositional and transactional coping strategies, anxiety and alexithymia were filled out by 77 participants in a longitudinal study design. Statistical analyses were performed using general linear models and partial least squares path modelling, low-constraint methods that are particularly useful in the behavioural sciences. While anxiety levels prior to the result announcement were predictive of the distress experienced by noncarriers, considerable variability was observed for mutation carriers. Some subjects who had lower anxiety levels before the test displayed greater anxiety afterwards, but others seemed to anticipate the distress they would experience with the result that they showed a decrease in anxiety. The mutation carriers behaved as though their adaptive functioning were reshaped by the test result, independent of their disposition and previous emotional state, except in the case of alexithymia. Difficulty expressing emotions prior to genetic testing contributed to a similar difficulty after receiving the result, adding to the latter's emotional impact by promoting emotion-focused coping strategies and increasing distress.
