Studies examining the structure and function of mindfulness in individuals with schizophrenia spectrum disorders including those at clinical high risk for psychosis
Integrating Mindfulness Into The Extended Process Model Of Emotion Regulation: The Dual-Mode Model Of Mindful Emotion Regulation
Extensive research has been conducted regarding how people manage their emotions. Within this research, there has been growing attention towards the role of mindfulness in emotion regulation. While prior reviews have discussed mindfulness in the context of emotion regulation, they have not provided a thorough integration using the prevailing models of emotion regulation or mindfulness. The present review discusses the Extended Process Model of Emotion Regulation and Monitoring and Acceptance Theory of mindfulness in order to propose a novel integrated framework, the Dual-mode Model of Mindful Emotion Regulation (D-MER). This model proposes two “modes” of mindfulness: Implementation and facilitation. Implementation posits that mindfulness skills can be used as emotion regulation strategies through attentional deployment and cognitive change. Facilitation posits that mindfulness as a state or trait affects emotion generation and regulation through effects on cognitive processes and positive or negative valence systems. Further, the D-MER posits that mindfulness experience can improve the efficiency of mindfulness-based emotion regulation strategies (implementation) while effects of mindfulness on emotion regulation processes become increasingly trait-like and automatic over time (facilitation). Empirical and theoretical support for this model are discussed, specific hypotheses to guide further research are provided, and clinical implications are presented. Use of this model may identify mechanisms underlying the interaction between mindfulness and emotion regulation which can be used in ongoing affective and clinical research
Ambulatory audio and video recording for digital phenotyping in schizophrenia: Adherence & data usability
Ambulatory audio and video recording provides a wealth of information which can be used for a broad range of applications, including digital phenotyping, telepsychiatry, and telepsychology. However, these technologies are in their infancy, and guidelines for their use and analysis have yet to be established. The current project used ambulatory assessment data from individuals with schizophrenia (N = 52) and controls (N = 55) over a week to assess factors influencing sufficiency and useability of video and audio data. Logistic multilevel models examined the effect of relevant variables on video provision and video quality. There was no difference by group in video provision or quality. Videos were less likely to be provided later in the study and later in the day. Video quality was lower later in the day, particularly for controls. Participants were more likely to provide videos if alone or at home than in other settings. Black participants were less likely to have analyzable video frames than White participants. These results suggest potential racial disparities in camera technologies and/or facial analysis algorithms. Implications of these findings and recommendations for future study development, such as instructions to provide to participants to optimize video quality, are discussed

Remote digital phenotyping in serious mental illness: Focus on negative symptoms, mood symptoms, and self-awareness
The serious mental illness (SMI) phenotype is marked by several different symptom domains and biomedical challenges. The nature of SMI renders in-person assessment challenging, due to problems in event recall, response biases, lack of experience in real-world functional domains, and difficulties identifying informants. Digital strategies offer a promising alternative to in-person assessments and allow for remote delivery of cognitive and social cognitive assessments in addition to continuous momentary assessment of activities, moods, symptoms, expressions, experiences, and psychophysiological variables. Remote assessments of mood, emotion, behavior, cognition, and self-assessment have been successfully collected across various SMI conditions. Both active (paging and triggered observations of facial and vocal expressions) and passive (global positioning, actigraphy) methods have been deployed remotely, similarly to in-person assessments previously conducted in the laboratory. Advanced strategies in data analysis are used to examine this information and to guide the development of newer advances in assessment of phenotypic variation in SMI
Reinforcement learning profiles and negative symptoms across chronic and clinical high-risk phases of psychotic illness
Background: Negative symptoms are prominent in individuals with schizophrenia (SZ) and youth at clinical high-risk for psychosis (CHR). In SZ, negative symptoms are linked to reinforcement learning (RL) dysfunction; however, previous research suggests implicit RL remains intact. It is unknown whether implicit RL is preserved in the CHR phase where negative symptom mechanisms are unclear, knowledge of which may assist in developing early identification and prevention methods. Methods: Participants from two studies completed an implicit RL task: Study 1 included 53 SZ individuals and 54 healthy controls (HC); Study 2 included 26 CHR youth and 23 HCs. Bias trajectories reflecting implicit RL were compared between groups and correlations with negative symptoms were examined. Cluster analysis investigated RL profiles across the combined samples. Results: Implicit RL was comparable between HC and their corresponding SZ and CHR groups. However, cluster analysis was able to parse performance heterogeneity across diagnostic boundaries into two distinct RL profiles: a Positive/Early Learning cluster (65% of participants) with positive bias scores increasing from the first to second task block, and a Negative/Late Learning cluster (35% of participants) with negative bias scores increasing from the second to third block. Clusters did not differ in the proportion of CHR vs. SZ cases; however, the Negative/Late Learning cluster had more severe negative symptoms. Conclusions: Although implicit RL is intact in CHR similar to SZ, distinct implicit RL phenotypic profiles with elevated negative symptoms were identified transphasically, suggesting distinct reward-processing mechanisms can contribute to negative symptoms independent of phases of illness

How do social factors relate to blunted facial affect in schizophrenia? A digital phenotyping study using ambulatory video recordings
Clinical interviews and laboratory-based emotional induction paradigms provide consistent evidence that facial affect is blunted in many individuals with schizophrenia. Although it is clear that blunted facial affect is not a by-product of diminished emotional experience in schizophrenia, factors contributing to blunted affect remain unclear. The current study used a combination of ambulatory video recordings that were evaluated via computerized facial affect analysis and concurrently completed ecological momentary assessment surveys to assess whether blunted affect reflects insufficient reactivity to affective or contextual factors. Specifically, whether individuals with schizophrenia require more intense affective experiences to produce expression, or whether they are less reactive to social factors (i.e. being in the presence of others, social motivation). Participants included outpatients with schizophrenia (n = 33) and healthy controls (n = 31) who completed six days of study procedures. Multilevel linear models were evaluated using both Null-Hypothesis Statistical Testing and Bayesian analyses. Individuals with schizophrenia displayed comparable expression of positive and negative emotion to controls during daily life, and no evidence was found for a different intensity of experience required for expression in either group. However, social factors differentially influenced facial expression in schizophrenia compared to controls, such that individuals with schizophrenia did not modulate their expressions based on social motivation to the same extent as controls. These findings suggest that social motivation may play an important role in determining when blunting occurs
