The Relation Between Short-Term Emotion Dynamics and Psychological Well-Being: A Meta-Analysis

Not only how good or bad people feel on average, but also how their feelings fluctuate across time is crucial for psychological health. The last 2 decades have witnessed a surge in research linking various patterns of short-term emotional change to adaptive or maladaptive psychological functioning, often with conflicting results. A meta-analysis was performed to identify consistent relationships between patterns of short-term emotion dynamics-including patterns reflecting emotional variability (measured in terms of within-person standard deviation of emotions across time), emotional instability (measured in terms of the magnitude of consecutive emotional changes), and emotional inertia of emotions over time (measured in terms of autocorrelation)-and relatively stable indicators of psychological well-being or psychopathology. We determined how such relationships are moderated by the type of emotional change, type of psychological well-being or psychopathology involved, valence of the emotion, and methodological factors. A total of 793 effect sizes were identified from 79 articles (N = 11,381) and were subjected to a 3-level meta-analysis. The results confirmed that overall, low psychological well-being co-occurs with more variable (overall ρ̂ = -.178), unstable (overall ρ̂ = -.205), but also more inert (overall ρ̂ = -.151) emotions. These effect sizes were stronger when involving negative compared with positive emotions. Moreover, the results provided evidence for consistency across different types of psychological well-being and psychopathology in their relation with these dynamical patterns, although specificity was also observed. The findings demonstrate that psychological flourishing is characterized by specific patterns of emotional fluctuations across time, and provide insight into what constitutes optimal and suboptimal emotional functioning.

Unraveling Affective Dysregulation in Borderline Personality Disorder: A Theoretical Model and Empirical Evidence

Although emotion dysregulation has consistently been conceptualized as a core problem of borderline personality disorder (BPD), a comprehensive, and empirically and ecologically validated model that captures the exact types of dysregulation remains absent. In the present article, we combine insights from basic affective science and the biosocial theory of BPD to present a theoretical model that captures the most fundamental affective dynamical processes that underlie BPD and stipulates that individuals with BPD are characterized by more negative affective homebases, higher levels of affective variability, and lower levels of attractor strength or return to baseline. Next, we empirically validate this proposal by statistically modeling data from three electronic diary studies on emotional responses to personally relevant stimuli in personally relevant environments that were collected both from patients with BPD (N = 50, 42, and 43) and from healthy subjects (N = 50, 24, and 28). The results regarding negative affective homebases and heightened affective variabilities consistently confirmed our hypotheses across all three datasets. The findings regarding attractor strengths (i.e., return to baseline) were less consistent and of smaller magnitude. The transdiagnostic nature of our approach may help to elucidate the common and distinctive mechanisms that underlie several different disorders that are characterized by affective dysregulation.

Emotional Inertia and External Events: The Roles of Exposure, Reactivity, and Recovery

Increased moment-to-moment predictability, or inertia, of negative affect has been identified as an important dynamic marker of psychological maladjustment, and increased vulnerability to depression in particular. However, little is known about the processes underlying emotional inertia. The current article examines how the emotional context, and peoples responses to it, are related to emotional inertia. We investigated how individual differences in the inertia of negative affect (NA) are related to individual differences in exposure, reactivity, and recovery from emotional events, in daily life (assessed using experience sampling) as well as in the lab (assessed using an emotional film-clip task), among 200 participants commencing their first year of tertiary education. This dual-method approach allowed us to assess affective responding on different timescales, and in response to standardized as well as idiographic emotional stimuli. Our most consistent finding, across both methods, was that heightened NA inertia is related to decreased NA recovery following negative stimuli, suggesting that higher levels of inertia may be mostly driven by impairments in affect repair following negative events.

The Emotion Regulation Function of Nonsuicidal Self-Injury: A Momentary Assessment Study in Inpatients With Borderline Personality Disorder Features.

Studies using retrospective self-report or proxies of nonsuicidal self-injury (NSSI) in the lab have shown that NSSI is often preceded by intense negative emotions and followed by a decrease in negative emotions/tension, suggesting an emotion regulation function of NSSI. To investigate this emotion regulation function of NSSI in a more ecologically valid way, we used experience sampling methods to examine the temporal relationship between NSSI behavior and emotional experiences throughout the day in 30 inpatients currently staying in psychiatric hospitals. Because NSSI is especially prevalent and severe in patients with a borderline personality disorder (BPD), we focused on patients with high levels of BPD symptomatology. Results confirmed that high levels of negative emotion prospectively predicted a higher probability of engaging in NSSI in the next time interval. However, the occurrence of NSSI itself was related to concurrent increases in negative emotion and decreases in positive emotion, and even prospectively predicted an increase in negative emotion in the consecutive time interval. These preliminary results show that on a time scale of hours, instead of resulting in emotional relief, NSSI seems to be associated with a further increase in negative emotionality, shedding light on the cyclic nature of NSSI.

Sad and alone: Social expectancies for experiencing negative emotions are linked to feelings of loneliness

Western culture has become obsessed with happiness, while treating negative emotions like sadness, depression, or anxiety as pathological and nonnormative. These salient cultural norms communicate social expectations that people should feel “happy” and not “sad.” Previous research has shown that these “social expectancies” can increase feelings of sadness and reduce well-being. In this study, we examined whether these perceived social pressures might also lead people to feel socially disconnected—lonely—when they do experience negative emotions? Drawing on a large stratified sample prescreened for depressive symptoms and utilizing both trait measures and moment-to-moment “experience sampling” over a 7-day period, we found that people who felt more negative emotions and also believe that others in society disapprove of these emotions reported more loneliness. Our data suggest that social pressures to be happy and not sad can make people feel more socially isolated when they do feel sad.

The specificity of emotional switching in borderline personality disorder in comparison to other clinical groups

In an attempt to better understand the nature of emotion dysregulation in the daily lives of persons with a borderline personality disorder (BPD), Houben et al. (2016) recently identified emotional switching, which refers to the tendency to make large changes between positive and negative emotional states over time, as a possible defining characteristic of the emotion dynamics observed in BPD. The goal of this study was to examine the specificity of these previous findings in 2 samples by comparing BPD patients (N = 43 in sample 1; N = 81 in sample 2) to patients with bulimia nervosa (N = 20), posttraumatic stress disorder (N = 28), or healthy controls (N = 28) in sample 1, and to patients with depressive disorder (N = 50) in sample 2, with respect to measures of emotional switching. Analyses of these 2 experience sampling datasets revealed that contrary to expectations, BPD patients did not differ from the clinical groups regarding their mere tendency to switch between positive and negative emotional states on consecutive moments over time and regarding the magnitude of such changes between positive and negative emotional states over time. However, all clinical groups did differ from healthy controls regarding all switch measures in dataset 1. These results indicate that emotional switching, similar to other more traditional indicators of overall changes in emotional intensity in daily life, might reflect a feature of emotional responding characterizing a range of disorders with mood disturbances.

Emotional Switching in Borderline Personality Disorder: A Daily Life Study

Despite large efforts to understand emotional instability in borderline personality disorder (BPD), it is still unclear exactly how this is manifested in the daily lives of people suffering from the disorder. Building on theoretical and clinical observations of BPD, we propose that the emotional instability in BPD particularly consists of the occurrence of strong changes between positive and negative emotional states from 1 moment to the next, labeled emotional switching. We tested this proposal by means of an experience sampling study in which 30 BPD patients and 28 healthy controls reported in their daily lives the level of pleasantness/unpleasantness of their emotional states 10 times a day for 8 consecutive days using handheld palmtops. Results showed that although BPD patients did not differ from healthy controls regarding their overall tendency to switch from a positive to a negative emotional state or vice versa, the size of such changes between positive and negative states was found to be significantly larger in BPD patients. In contrast, the magnitude of emotional changes that remained within the negative emotional range or positive emotional range was not particularly larger for BPD patients compared with healthy participants. These findings imply that the emotional instability in BPD is particularly characterized by larger changes from positive to negative states and vice versa, rather than overall larger changes in intensity, providing insight into possible processes underlying emotion dysfunction in BPD.

The bipolarity of affect and depressive symptoms.

People differ in the extent to which they experience positive (PA) and negative affect (NA) rather independently or as bipolar opposites. Here, we examine the proposition that the nature of the relation between positive and negative affect in a person’s emotional experience is indicative of psychological well-being, in particular the experience of depressive symptoms, typically characterized by diminished positive affect (anhedonia) and increased negative affect (depressed mood). In three experience sampling studies, we examine how positive and negative affective states are related within people’s emotional experience in daily life and how the degree of bipolarity of this relation is associated with depressive symptom severity. In Study 1 and 2, we show both concurrently and longitudinally that a stronger bipolar PA–NA relationship is associated with, and in fact is predicted by, higher depressive symptom severity, even after controlling for mean levels of positive and negative affect. In Study 3, we replicate these findings in a daily diary design, with the two conceptually related main symptoms of depression, sadness, and anhedonia, as specific manifestations of high NA and low PA, respectively. Across studies, additional analyses indicate these results are robust across different time scales and various PA and NA operationalizations and that affective bipolarity shows particular specificity toward depressive symptomatology, in comparison with anxiety symptoms. Together, these findings demonstrate that depressive symptoms involve stronger bipolarity between positive and negative affect, reflecting reduced emotional complexity and flexibility.

The relationship between non-suicidal self-injury and alexithymia in borderline personality disorder: “Actions instead of words”

INTRODUCTION Borderline personality disorder (BPD) is a serious mental illness that centers on the inability to effectively regulate emotions. A large amount of BPD patients engage in non-suicidal self-injury (NSSI). Given the NSSI contributes to serious health risks, it is important to know why some BPD patients engage in NSSI and others do not. A possible associated factor of NSSI in BPD may be alexithymia, which reflects difficulties in identifying and communicating feelings. Therefore the aim of the present study was to investigate whether NSSI was associated with alexithymia and whether this association still stood when controlling for gender and depression. METHODS The current study explored the relationship between NSSI and alexithymia in 185 BPD patients by means of the Self-Injury Questionnaire-Treatment Related and the Toronto Alexithymia Scale-20 (TAS). RESULTS Of the 185 BPD inpatients, 82.7% reported life-time NSSI, of whom 52.9% were still engaging in current NSSI; and 71.3% scored in the alexithymic range (cut-off score≥61). Current NSSI was significantly associated with TAS-total. Additionally, when considering the separate TAS subscales Difficulties Describing Feelings (DDF), Difficulties Identifying Feelings (DIF) and Externally Oriented Thinking (EOT), only DDF was significantly associated with NSSI, even after controlling for gender and depression. CONCLUSION These results suggest that NSSI in BPD patients is associated with alexithymia. More specific, difficulties describing feelings can lead to NSSI, independently of the depressive status of the BPD patient. The implications for clinical treatment of self-injurious BPD patients will be discussed.

The affect stabilization function of nonsuicidal self injury in borderline personality disorder: An ecological momentary assessment study.

Nonsuicidal Self-Injury (NSSI) is prominent in individuals with Borderline Personality Disorder (BPD), and there is abundant evidence that affect regulation plays an important role in NSSI in the majority of patients. Affective variability is a core feature of BPD, and thus, we hypothesize that NSSI has an affect stabilization function in BPD. Affect stabilization is a process through which individuals attempt to make their affect more stable by reducing affective variability. We tested this hypothesis in 32 participants with BPD who reported on their NSSI and affect -using a displeasure-pleasure (valence) and activation-deactivation (activation) dimension- in an experience sampling study with 10 random signals scheduled per day for 8 days. Results indicated that individuals who engaged in NSSI show more Within Subject (WS) variance in valence and activation than individuals who did not engage in NSSI. However, within the NSSI patients, individuals who engaged more frequently in NSSI during the study showed less WS variance in valence and activation than patients who engaged less frequently in NSSI. This suggests that NSSI may be reinforced by its affect stabilization function. In the discussion, we explore alternative explanations for the relation between NSSI and affective variability, and consider the clinical implications.
