Background While mindfulness apps have received growing clinical attention, their integration within health systems has received limited empirical investigation. In this study, we evaluated a mindfulness app as a low-intensity treatment option for adults waiting for psychological services. A non-randomized clinical trial was conducted with a 4-week...

Background Borderline personality disorder (BPD) is considered a disorder of emotion regulation resulting from the expression of a biologically determined emotional vulnerability (that is, heightened sensitivity to emotion, increased emotional intensity/reactivity, and a slow return to emotional baseline) combined with exposure to invalidating envi...

Monitoring sleep and activity through wearable devices such as wrist-worn actigraphs has the potential for long-term measurement in the individual’s own environment. Long periods of data collection require a complex approach, including standardized pre-processing and data trimming, and robust algorithms to address non-wear and missing data. In this...

BACKGROUND People with alcohol and substance use disorders (SUDs) often have underlying difficulties in regulating emotions. While dialectical behavioral therapy (DBT) is effective for SUDs, it is often difficult to access. Self-guided, Internet-delivered DBT (iDBT) allows for expanded availability, but few studies have rigorously evaluated it with...

Background: Biases in social reinforcement learning, or the process of learning to predict and optimize behavior based on rewards and punishments in the social environment, may underlie and maintain some negative cognitive biases that are characteristic of social anxiety. However, little is known about how cognitive and behavioral interventions ma...

Background: Rumination is strongly associated with depressive symptom severity and course. However, changes in rumination during outpatient cognitive behavioral therapy (CBT), and their links to baseline features such as distress tolerance and clinical outcomes, have received limited attention. Methods: 278 outpatients with depression received g...

Background: People with depression select avoidant emotion regulation (ER) strategies more often than engagement strategies. While psychotherapy improves ER strategies, examining the week-to-week changes in ER and their relationship to clinical outcomes is warranted to understand how these interventions work. This study examined the changes in six...

Long periods of data collection require a complex approach, including standardized pre-processing and data trimming, and robust algorithms to address non-wear and missing data. In this...

Unlabelled: Most research on emotion regulation has focused on understanding individual emotion regulation strategies. Preliminary research, however, suggests that people often use several strategies to regulate their emotions in a given emotional scenario (polyregulation). The present research examined who uses polyregulation, when polyregulation...

BACKGROUND Biases in social reinforcement learning, or the process of learning to predict and optimize behavior based on rewards and punishments in the social environment, may underlie and maintain some of the negative cognitive biases that are characteristic of social anxiety. However, little is known about how cognitive and behavioral interventio...

Introduction: The current studies examined how smartphone-assessed contextual features (i.e., location, time-of-day, social situation, and affect) contribute to the relative likelihood of emotion regulation strategy endorsement in daily life. Methods: Emotion regulation strategy endorsement and concurrent contextual features were assessed either pa...

Difficulties in applying emotional regulation (ER) skills are associated with depression and anxiety symptoms, and are common targets of treatment. This meta-analysis examined whether improvements in ER skills were associated with psychological treatment outcomes for depression and/or anxiety in youth. A multivariate, random-effects meta-analysis w...

Although definitions of emotion dysregulation infer difficulties in selecting and implementing emotion regulation (ER) strategies, surprisingly few studies have examined the relationship between trait emotion dysregulation and a wide range of specific ER strategies. The present study used a data-driven approach to assess trait- and state-related ER...

Although impulsivity has been implicated in cannabis and alcohol use, its role in alcohol and cannabis co-use behavior requires further study. We examined the moderating role of self-report and behavioral measures of impulsivity in the daily-level relationships between cannabis use and both (a) likelihood of same-day alcohol use and (b) the number...

Objectives: Poor emotion regulation (ER) has been implicated in many mental illnesses, including social anxiety disorder. To work towards a scalable, low-cost intervention for improving ER, we developed a novel contextual recommender algorithm for ER strategies. Design: N = 114 socially anxious participants were prompted via a mobile app up to s...

Background The coronavirus disease 2019 (COVID-19) pandemic has caused global disruptions with serious psychological impacts. This study investigated the emergence of new psychiatric symptoms and the worsening of pre-existing mental disorders during the COVID-19 pandemic, identified factors associated with psychological worsening, and assessed chan...

Background The extent to which a person believes they can change or control their own emotions is associated with trait-level symptoms of mood and anxiety-related psychopathology.Method The present study examined how this belief relates to momentary and daily self-reports of affect, emotion regulation tendencies, and perceived effectiveness of emot...

Summary This study aimed to evaluate changes in sleep during the COVID‐19 outbreak, and used data‐driven approaches to identify distinct profiles of changes in sleep‐related behaviours. Demographic, behavioural and psychological factors associated with sleep changes were also investigated. An online population survey assessing sleep and mental heal...

Introduction The negative impacts of COVID-19 have rippled through every facet of society. Understanding the multidimensional impacts of this pandemic is crucial to identify the most critical needs and to inform targeted interventions. This population survey study aimed to investigate the acute phase of the COVID-19 outbreak in terms of perceived t...

To work towards a scalable, low-cost intervention for improving ER, we developed a novel contextual recommender algorithm for ER strategies. Design: N=114 socially anxious participants were prompted via a mobile app up to six ti...

We examined how anxiety sensitivity - the fear of symptoms of anxiety due to their perceived harmful effects - and gender are associated with treatment trajectory and outcomes in a large outpatient sample (N = 278) who received 14-weeks of cognitive-behavioral group therapy (CBGT) for depression. Three dimensions of anxiety sensitivity (cognitive,...

Background Understanding the multifaceted impacts of the Coronavirus-19 (COVID-19) outbreak as it unfolds is crucial to identify the most critical needs and to inform targeted interventions. Methods This population survey study presents cohort characteristics and baseline observations linked to the acute-mid phase of the COVID-19 outbreak in terms...

Background Reducing one’s tendency to interpret ambiguous situations negatively can improve symptoms of social anxiety. This study examines the effectiveness of a 1-week period of online Cognitive Bias Modification for Interpretations (CBM-I) for socially anxious individuals. In addition to measuring intervention effectiveness through traditional t...

Although definitions of emotion dysregulation infer difficulties in selecting and implementing emotion regulation (ER) strategies, surprisingly few studies have examined the relationship between trait emotion dysregulation and a wide range of ER strategies. The current study used a data-driven approach to assess ER strategies in 99 women (aged 18-5...

Few studies have examined how trait emotion dysregulation relates to momentary affective experiences and the emotion regulation (ER) strategies people use in daily life. In the current study, 112 college students completed a trait measure of emotion dysregulation and completed experience sampling and end-of-day surveys over a two- to three-week per...

Socially anxious individuals typically select more avoidant emotion regulation (ER) strategies than non-anxious individuals, contributing to interpersonal difficulties. The present study utilized smartphone-delivered experience sampling over 14 days to assess how actual and desired social situations predicted reports of ER strategy use in 115 under...

Emotion dysregulation is often considered a core characteristic of individuals with borderline personality disorder (BPD). With the development and strength of a contemporary affective-science model that encompasses both healthy emotion regulation (ER) and emotion dysregulation, this model has increasingly been used to understand the affective expe...

Background Borderline personality disorder (BPD) is characterized by a heterogeneous clinical phenotype that emerges from interactions among genetic, biological, neurodevelopmental, and psychosocial factors. In the present family study, we evaluated the familial aggregation of key clinical, personality, and neurodevelopmental phenotypes in probands...

Mental health problems are a leading cause of disease burden and disability worldwide. Social anxiety and depression are highly prevalent among college students. The current methods for detecting symptoms are based on client self-report via questionnaires and interviews in traditional clinical settings, but self-report is subject to recall bias and...

Individuals with borderline personality disorder (BPD) report using cognitive reappraisal less often than healthy individuals despite the long-term benefits of the emotion regulation strategy on emotional stability. Individuals with BPD, mixed anxiety and/or depressive disorders (MAD), and healthy controls (HC) completed an experimental task to inv...

Individuals with borderline personality disorder (BPD) have difficulties regulating emotions, which may be a consequence of using less effective emotion regulation (ER) strategies to lessen the intensity of their negative emotions. It is not yet known whether people with BPD utilize particular ER strategies to modulate specific mood states and if t...

Background: Although difficulties in emotion regulation (ER) are considered a core feature of borderline personality disorder (BPD), the specific strategies that individuals with BPD most commonly use, their diagnostic specificity, and their associations with harmful behaviors have not been firmly established. Sampling and methods: Individuals w...

Negative affect is a proxy for mental health in adults. By being able to predict participants' negative affect states unobtrusively, researchers and clinicians will be better positioned to deliver targeted, just-in-time mental health interventions via mobile applications. This work attempts to personalize the passive recognition of negative affect...

Significant research exists exploring goal orientation in the context of emotionally-relevant variables, such as depression and self-esteem. However, almost no research exists examining the relationship between goal orientation and emotion regulation. Further, the interaction between goal orientation as a situational variable (imposed orientation)...

Although appearance-based cues can help to diagnose physical illness, visual manifestations of mental disorder may be more elusive. Here, we investigated whether individuals could distinguish women with a serious mental disorder (borderline personality disorder) from demographically- and IQ-matched non-psychiatric controls. Participants rated menta...

Risk for potentially lethal self-injurious behavior in borderline personality disorder (BPD) may be associated with deficits in neuropsychological functions and social cognition. In particular, individuals with BPD engaging in more medically damaging self-injurious behaviors may have more severe executive function deficits and altered emotion perce...

A well-documented dissociation between memory encoding and retrieval concerns the role of attention in the two processes. The typical finding is that divided attention (DA) during encoding impairs future memory, but retrieval is relatively robust to attentional manipulations. However, memory research in the past 20 years had demonstrated that retri...

Individuals with borderline personality disorder (BPD) have biases in facial emotion recognition, which may underlie many of the core features of this disorder. Although they are known to misperceive specific prototypic expressions of emotion (i.e., those displayed at full emotional intensity), patients with this disorder may also show biases in th...

Background. Emotion dysregulation represents a core symptom of borderline personality disorder (BPD). Deficits in emotion perception are thought to underlie this clinical feature, although studies examining emotion recognition abilities in BPD have yielded inconsistent findings. Method. The results of 10 studies contrasting facial emotion recogniti...

To examine whether disgust recognition deficits are present and specific to obsessive-compulsive disorder (OCD), and the extent to which this deficit, if present, can be reduced in cognitive-behavioural therapy (CBT). Responses to the Pictures of Facial Affect (POFA) were examined in patients with Diagnostic and Statistical Manual of Mental Disorde...

The acoustic startle reflex is strongly inhibited by a moderate-intensity acoustic stimulus that precedes the startling stimulus by roughly 10-1000 ms (prepulse inhibition, PPI). At long interstimulus intervals (ISIs) of 100-1000 ms, PPI in rats is reduced by the muscarinic receptor antagonist scopolamine. Here, we studied the role of GABA receptor...
