RESUMO

OBJECTIVE: This study examined the temporal dynamics of anxiety and depressive symptoms during a 12-week therapist-supported, smartphone-delivered digital health intervention for symptoms of depression and anxiety. METHODS: A total of 290 participants were included in the present analyses (age Mean = 39.64, SD = 10.25 years; 79% female; 54% self-reported psychotropic medication use). Linear mixed models were used to examine the concurrent anxiety-depression association and (2) the lead-lag anxiety-depression relationship, with greater anxiety predicted to precede an increase in depression. RESULTS: In support of Hypothesis 1, greater anxiety during the current biweekly assessment was associated with greater depressive symptoms during the current biweekly assessment. In support of Hypothesis 2, greater anxiety during the prior biweekly assessment was associated with greater depressive symptoms during the current biweekly assessment but not vice-versa. CONCLUSION: These findings demonstrate that anxiety and depressive symptoms may overlap and fluctuate in concert, with anxiety symptoms predicting subsequent depressive symptoms but not vice-versa. With sensitivity to study limitations, implications for future intervention designs are discussed.

RESUMO

Social anxiety disorder (SAD) is characterized by negative self-referential processing, which triggers excessive emotional reactivity. In healthy individuals, positive self-views typically predominate and are supported by regions of the default mode network (DMN) that represent self-related information and regions of the frontoparietal control network (FPCN) that contribute to metacognitive awareness and emotion regulation. The current study used functional magnetic resonance imaging (fMRI) to examine patterns of DMN and FPCN activation during positive and negative self-referential judgments in SAD patients (N = 97) and controls (N = 34). As expected, SAD patients demonstrated a striking difference in self-beliefs compared with non-anxious healthy controls, endorsing fewer positive traits and more negative traits. However, SAD patients and controls demonstrated largely similar patterns of DMN and FPCN recruitment during self-referential judgements. No significant group differences were observed. However, equivalence testing identified numerous regions demonstrating effect sizes that were not small enough to conclude that they were practically equivalent to zero, despite the nonsignificant null hypothesis test. These regions may be key targets to investigate in future studies using larger samples.

RESUMO

Emotion regulation (ER) is an important skill for well-being. Cognitive reappraisal is a goal-oriented cognitive change strategy. Acceptance involves decentering from immediate habits of reactivity, observing moment-to-moment shifts in thoughts, emotions, and sensations. These two regulation strategies are thought to have different effects on emotion; however, no study has examined the differential effects of reappraisal and acceptance on behavioral, autonomic, and brain responses in the context of ideographic personally salient negative self-beliefs. Thirty-five right-handed, healthy adults were presented idiographic negative self-beliefs embedded in autobiographical scripts. We measured negative emotion ratings, autonomic psychophysiology, and functional magnetic resonance imaging blood oxygen-level dependent responses while participants read neutral statements, reacted to their own negative self-beliefs, and implemented reappraisal and acceptance strategies. Compared with react, reappraisal resulted in significantly lesser negative emotion and respiration rate; no differences in heart rate and skin conductance level; greater brain responses implicated in cognitive control, language, and social cognition; and lesser amygdala responses. Compared with react, acceptance resulted in significantly lesser negative emotion, respiration rate, and heart rate; no difference in skin conductance level; and greater brain responses in networks implicated in cognitive control and attention. Compared with acceptance, reappraisal resulted in significantly lesser negative emotion; no difference in respiration rate and skin conductance level; higher heart rate; greater brain responses in brain regions implicated in cognitive control; and lesser brain responses in amygdala. Reappraisal is more effective than acceptance in down-regulating negative emotion, but may require greater recruitment of autonomic, cognitive, and brain resources.

RESUMO

Many psychiatric disorders involve problematic patterns of emotional reactivity and regulation. In this review, we consider recent findings regarding emotion and emotion regulation in the context of social anxiety disorder (SAD). We first describe key features of SAD which suggest altered emotional and self-related processing difficulties. Next, we lay the conceptual foundation for a discussion of emotion and emotion regulation and present a common framework for understanding emotion regulation, the process model of emotion regulation. Using the process model, we evaluate the recent empirical literature spanning self-report, observational, behavioral, and physiological methods across five specific families of emotion regulation processes-situation selection, situation modification, attentional deployment, cognitive change, and response modulation. Next, we examine the empirical evidence behind two psychosocial interventions for SAD: cognitive behavioral therapy (CBT) and mindfulness-based stress reduction (MBSR). Throughout, we present suggestions for future directions in the continued examination of emotion and emotion regulation in SAD.

RESUMO

INTRODUCTION: Elevated fear of negative evaluation (FNE) and fear of positive evaluation (FPE) are thought to play key roles in the maintenance of social anxiety disorder (SAD). Although efficacious therapies exist for SAD, the potential mediating and moderating effects of FNE and FPE on social anxiety treatment outcome have not been examined. METHODS: This sample comprised a secondary analysis of 210 individuals who participated in one of three randomized controlled trials for the treatment of SAD. Participants were randomized to: individual cognitive behavioral therapy (CBT), group CBT, community mindfulness-based stress reduction (MBSR), group MBSR, or they were randomized to waitlist and offered treatment after waitlist. Assessments were completed pre- and post-treatment/waitlist and, for the treatment groups, at three-month follow-up. RESULTS: CBT and MBSR led to greater reductions in FNE and FPE than waitlist, with CBT more efficacious in reducing FPE than MBSR. For both CBT (vs. waitlist) and MBSR (vs. waitlist), there were significant indirect effects on post-treatment social anxiety through both FNE and FPE, and the indirect effect through FPE was greater for CBT than MBSR. However, in the fully longitudinal model testing mediation, CBT and MBSR were not differentially mediated by FPE. Baseline FNE and FPE each moderated CBT treatment outcome compared to waitlist - higher baseline FNE and FPE were associated with higher baseline social anxiety and greater reductions in social anxiety during CBT. DISCUSSION: FNE and FPE contributed in sometimes similar and sometimes distinct ways to the mediation and moderation of psychosocial approaches for treating SAD. This supports the importance of distinguishing between fears of negative and positive evaluation in the assessment and treatment of SAD.

RESUMO

PURPOSE: This study examined treatment outcomes (depression and anxiety symptoms) up to 24 months after completion of a therapist-supported digital mental health intervention (DMHI). METHODS: The sample consisted of 380 participants who participated in an eight-week DMHI from February 6, 2017 to May 20, 2019. Participants reported depression and anxiety symptoms at eight timepoints from baseline to 24 months. Mixed-effects modelling was used to investigate symptom changes over time. The proportion of participants meeting criteria for treatment response, clinically significant change, and remission of depression and anxiety symptoms were calculated, including proportions demonstrating each outcome sustained up to each timepoint. RESULTS: Multivariate analyses yielded statistically significant reductions in depression (ß = -5.40) and anxiety (ß = -3.31) symptoms from baseline to end of treatment (8 weeks). Symptom levels remained significantly reduced from baseline through 24 months. The proportion of participants meeting criteria for clinical treatment outcomes remained constant over 24 months, although there were linear decreases in the proportions experiencing sustained clinical outcomes. CONCLUSIONS: Treatment gains were made for depression and anxiety symptoms at the end of treatment and up to 24 months. Future studies should determine the feasibility of integrating post-treatment programmes into DMHIs to address symptom deterioration.

RESUMO

The bivalent fear of evaluation (BFOE) model of social anxiety divides fear of evaluation into two distinct valences: fear of positive evaluation (FPE) and fear of negative evaluation (FNE). However, there is evidence that the two most widely utilized and psychometrically supported measures of FNE and FPE contain items which are ambiguous with regard to valence of evaluative fear. To formally address this, the BFOE Scale (BFOES) was developed, by merging items from measures of FNE and FPE into a single scale with an integrated response format. The present studies examined the psychometric profile of the BFOES across a large pooled archival dataset (N = 2216), which included approximately 10 % (n = 224) patients with social anxiety disorder (SAD). The factorial validity, internal consistency, and construct validity of the BFOES were examined. Additionally, item response theory analyses were employed for the purpose of merging items from self-report scales which utilized different Likert-type response formats. Results from both studies provided support for the psychometric profile of the BFOES. The implications of the BFOES for the assessment of social anxiety, and theoretical models of fear of evaluation and SAD, are discussed.

RESUMO

OBJECTIVE: The aim is to examine whether the addition of Virtual Reality (VR) meditation training to a standard 8-week Mindfulness-Based Health Care Program (MBHC-VR) results in a significantly increased improvement in occupational, mental health, and psychological functioning versus MBHC-only in university students. MATERIALS AND METHODS: A randomized controlled clinical trial with three arms (MBHC, MBHC-VR, Control Group), four assessment time points (pre-intervention, inter-session, post-intervention, and 3-month follow-up), and mixed methodology will be proposed. University students (undergraduate, master, or doctoral) interested in participating and who meet the inclusion/exclusion criteria will be included over two years. Data will be collected from different ad hoc questionnaires, several standardized tests, and an Ecological Momentary Assessment. We will use R software to carry out descriptive analyses (univariate and bivariate), multilevel modeling, and structural equation models to respond to the proposed objective. The qualitative analysis will be carried out using the MAXQDA program and the technique of focus groups. DISCUSSION: It is expected that with the proposed intervention university students will learn to relate in a healthier way with their mental processes, so as to improve their occupational balance (OB) and their psychological well-being.

RESUMO

BACKGROUND: The relationship between gaze avoidance and social anxiety has been examined previously using eye-tracking and static social images. Overall, findings to date highlight increased gaze avoidance as a behavioral marker of social anxiety. The purpose of the present study was to better elucidate the relationship between gaze avoidance and social anxiety disorder (SAD) symptoms via covert eye tracking of gaze tendencies in response to a dynamic computerized social interaction simulation. On the basis of the bivalent fear of evaluation (BFOE) model of social anxiety,([1]) it was expected that participants with SAD, compared to nonsocially anxious control (NSAC) participants, would exhibit gaze avoidance in response to both positive and negative social feedback. METHODS: Participants with SAD (n = 20), and a sample of demographically equivalent NSAC (n = 19), were administered clinical diagnostic interviews and a computerized social simulation task. The simulation task consisted of viewing 26 dynamic videos (13 positive and 13 negative), each 12 s in duration. All participants were covertly eye tracked during the simulation. RESULTS: SAD participants exhibited greater global gaze avoidance in response to both the positive and negative video clips in comparison to the controls. Moreover, the SAD group exhibited equivalent gaze avoidance in response to stimuli of both emotional valences. CONCLUSIONS: These results provide additional support for gaze avoidance as a behavioral marker of SAD, as well as additional support for the BFOE model. Implications for the assessment of SAD are discussed.

RESUMO

BACKGROUND: The association between childhood maltreatment-particularly emotional maltreatment-and social anxiety disorder (SAD) has been established by research. Only recently have researchers begun to look at the impact of childhood maltreatment on treatment outcomes, and findings have been mixed. Because prior studies have focused on pharmacotherapy outcomes, or used global measures of childhood adversity or abuse, it is not clear how specific types of maltreatment impact outcomes in cognitive-behavioral therapy (CBT) for SAD. The current study reports on how specific types of childhood maltreatment such as physical abuse, emotional abuse, sexual abuse, physical neglect, and emotional neglect impact response to CBT in adults with SAD. METHODS: Sixty-eight individuals with a primary diagnosis of SAD completed the childhood trauma questionnaire, along with measures of social anxiety, disability, and life satisfaction. RESULTS: Childhood maltreatment did not affect the rate of response to CBT, but there is evidence for its negative impact. Patients with histories of emotional abuse and emotional neglect reported greater social anxiety, less satisfaction, and greater disability over the course of treatment. Sexual abuse also predicted greater social anxiety. CONCLUSIONS: Childhood abuse and/or neglect did not result in differential rates of improvement during CBT; however, those reporting histories of emotional and sexual forms of maltreatment evidenced greater symptoms and/or impairment at pre- and posttreatment. Additional attention to the role of traumatic experiences within CBT for SAD may be warranted.

RESUMO

One foundational distinction in affective science is between emotion reactivity and regulation. This conceptual distinction has long been assumed to be instantiated in spatially separable brain systems (a typical example: amygdala/insula for reactivity and frontoparietal areas for regulation). In this research, we begin by reviewing previous findings that support and contradict the neural separability hypothesis concerning emotional reactivity and regulation. Further, we conduct a direct test of this hypothesis with empirical data. In five studies involving healthy and clinical samples (total n = 336), we assessed neural responses using fMRI while participants were asked to either react naturally or regulate their emotions (using reappraisal) while viewing emotionally evocative stimuli. Across five studies, we failed to find support for the neural separability hypothesis. In univariate analyses, both presumptive "reactivity" and "regulation" brain regions demonstrated equal or greater activation for the reactivity contrast than for the regulation contrast. In multivariate pattern analyses (MVPA), classifiers decoded reactivity (vs. neutral) trials more accurately than regulation (vs. reactivity) trials using multivoxel data in both presumptive "reactivity" and "regulation" regions. These findings suggest that emotion reactivity and regulation-as measured via fMRI-may not be as spatially separable in the brain as previously assumed. Our secondary whole-brain analyses revealed largely consistent results. We discuss the two theoretical possibilities regarding the neural separability hypothesis and offer thoughts for future research.

RESUMO

OBJECTIVE: Effective treatments for social anxiety disorder (SAD) exist, but additional treatment options are needed for nonresponders as well as those who are either unable or unwilling to engage in traditional treatments. Mindfulness-based stress reduction (MBSR) is one nontraditional treatment that has demonstrated efficacy in treating other mood and anxiety disorders, and preliminary data suggest its efficacy in SAD as well. METHOD: Fifty-six adults (52% female; 41% Caucasian; age mean [M] ± standard deviation [SD]: 32.8 ± 8.4) with SAD were randomized to MBSR or an active comparison condition, aerobic exercise (AE). At baseline and post-intervention, participants completed measures of clinical symptoms (Liebowitz Social Anxiety Scale, Social Interaction Anxiety Scale, Beck Depression Inventory-II, and Perceived Stress Scale) and subjective well-being (Rosenberg Self-Esteem Scale, Satisfaction with Life Scale, Self-Compassion Scale, and UCLA-8 Loneliness Scale). At 3 months post-intervention, a subset of these measures was readministered. For clinical significance analyses, 48 healthy adults (52.1% female; 56.3% Caucasian; age [M ± SD]: 33.9 ± 9.8) were recruited. MBSR and AE participants were also compared with a separate untreated group of 29 adults (44.8% female; 48.3% Caucasian; age [M ± SD]: 32.3 ± 9.4) with generalized SAD who completed assessments over a comparable time period with no intervening treatment. RESULTS: A 2 (Group) x 2 (Time) repeated measures analyses of variance (ANOVAs) on measures of clinical symptoms and well-being were conducted to examine pre-intervention to post-intervention and pre-intervention to 3-month follow-up. Both MBSR and AE were associated with reductions in social anxiety and depression and increases in subjective well-being, both immediately post-intervention and at 3 months post-intervention. When participants in the randomized controlled trial were compared with the untreated SAD group, participants in both interventions exhibited improvements on measures of clinical symptoms and well-being. CONCLUSION: Nontraditional interventions such as MBSR and AE merit further exploration as alternative or complementary treatments for SAD.

RESUMO

INTRODUCTION: The Cognitive Distortions Questionnaire (CD-Quest) is a self-report questionnaire that assesses common cognitive distortions. Although the CD-Quest has excellent psychometric properties, its length may limit its use. METHODS: We attempted to develop short-forms of the CD-Quest using RiskSLIM - a machine learning method to build short-form scales that can be scored by hand. Each short-form was fit to maximize concordance with the total CD-Quest score for a specified number of items based on an objective function, in this case R2, by selecting an optimal subset of items and an optimal set of small integer weights. The models were trained in a sample of US undergraduate students (N = 906). We then validated each short-form on five independent samples: two samples of undergraduate students in Brazil (Ns = 182, 183); patients with depression in Brazil (N = 62); patients with social anxiety disorder in the US (N = 198); and psychiatric outpatients in Turkey (N = 269). RESULTS: A 9-item short-form with integer scoring was created that reproduced the total 15-item CD-Quest score in all validation samples with excellent accuracy (R2 = 90.4-93.6%). A 5-item ultra-short-form had good accuracy (R2 = 78.2-85.5%). DISCUSSION: A 9-item short-form and a 5-item ultra-short-form of the CD-Quest both reproduced full CD-Quest scores with excellent to good accuracy. These shorter versions of the full CD-Quest could facilitate measurement of cognitive distortions for users with limited time and resources.

RESUMO

Anticipatory emotional responses play a crucial role in preparing individuals for impending challenges. They do this by triggering a coordinated set of changes in behavioral, autonomic, and neural response systems. In the present study, we examined the biobehavioral impact of varying levels of anticipatory anxiety, using a shock anticipation task in which unpredictable electric shocks were threatened and delivered to the wrist at variable intervals and intensities (safe, medium, strong). This permitted investigation of a dynamic range of anticipatory anxiety responses. In two studies, 95 and 51 healthy female participants, respectively, underwent this shock anticipation task while providing continuous ratings of anxiety experience and electrodermal responding (Study 1) and during fMRI BOLD neuroimaging (Study 2). Results indicated a step-wise pattern of responding in anxiety experience and electrodermal responses. Several brain regions showed robust responses to shock anticipation relative to safe trials, including the hypothalamus, periaqueductal gray, caudate, precentral gyrus, thalamus, insula, ventrolateral PFC, dorsomedial PFC, and ACC. A subset of these regions demonstrated a linear pattern of increased responding from safe to medium to strong trials, including the bilateral insula, ACC, and inferior frontal gyrus. These responses were modulated by individual differences in neuroticism, such that those high in neuroticism showed exaggerated anxiety experience across the entire task, and reduced brain activation from medium to strong trials in a subset of brain regions. These findings suggest that individual differences in neuroticism may influence sensitivity to anticipatory threat and provide new insights into the mechanism through which neuroticism may confer risk for developing anxiety disorders via dysregulated anticipatory responses.

RESUMO

INTRODUCTION: Individuals with social anxiety disorder (SAD) are at elevated risk of loneliness, yet little research has examined loneliness in this population. Cognitive-behavioral group therapy (CBGT) and mindfulness-based stress reduction (MBSR) have demonstrated efficacy in treating SAD, yet research has not examined whether they lead to reductions in loneliness. METHODS: This sample comprised 108 individuals with SAD who were randomized to CBGT, MBSR, or a waitlist control (WL); WL participants were re-randomized to CBGT or MBSR following WL. Assessments were completed pre- and post-treatment, and 3-, 6-, 9-, and 12-month follow-up assessments. RESULTS: Compared to WL, individuals in CBGT and MBSR were less lonely at post-treatment; there was no difference between treatments after treatment or during follow-up. Greater reductions in social anxiety from pre- to post-treatment predicted lower levels of loneliness during follow-up. Greater reductions in loneliness from pre- to post-treatment also predicted lower levels of social anxiety during follow-up. DISCUSSION: Individuals who experience reductions in their social anxiety during treatment may also feel less lonely following treatment. Reductions in loneliness also lead to improvements in social anxiety. Future research should continue to examine the relationship between social anxiety and loneliness and how interventions for SAD may help reduce loneliness.

RESUMO

Importance: Cognitive behavioral group therapy (CBGT) and mindfulness-based stress reduction (MBSR) are thought to help patients with social anxiety disorder (SAD) via distinct emotion-regulation mechanisms. However, no study has compared the effects of CBGT and MBSR on brain and negative emotion indicators of cognitive reappraisal and acceptance in patients with SAD. Objective: To investigate the effects of CBGT and MBSR on reappraisal and acceptance in patients with SAD and to test whether treatment-associated brain changes are associated with social anxiety symptoms 1 year posttreatment. Design, Setting, and Participants: In this randomized clinical trial, a total of 108 unmedicated adults diagnosed with generalized SAD were randomly assigned to 12 weeks of CBGT, MBSR, or waitlist. The final sample included 31 patients receiving CBGT, 32 patients receiving MBSR, and 32 waitlist patients. Data were collected at the psychology department at Stanford University from September 2012 to December 2014. Data were analyzed from February 2019 to December 2020. Interventions: CBGT and MBSR. Main Outcomes and Measures: Changes in self-reported negative emotion and functional magnetic resonance imaging (fMRI) blood oxygen level-dependent (BOLD) signal within an a priori-defined brain search region mask derived from a meta-analysis of cognitive reappraisal and attention regulation 1 year posttreatment. Results: Of 108 participants, 60 (56%) were female. The mean (SD) age was 32.7 (8.0) years. Self-reported race and ethnicity data were collected to inform the generalizability of the study to the wider population and to satisfy the requirements of the National Institutes of Health. From the categories provided by the National Institutes of Health, 47 participants selected White (43.5%), 42 selected Asian (38.9%) 10 selected Latinx (9.3%), 1 selected Black (1%), 1 selected Native American (1%), and 7 selected more than 1 race (6.5%). CBGT and MBSR were associated with a significant decrease in negative emotion (partial η2 range, 0.38 to 0.53) with no significant between-group differences when reacting (ß, -0.04; SE, 0.09; 95% CI, -0.11 to 0.08; t92 = -0.37; P = .71), reappraising (ß, -0.15; SE, 0.09; 95% CI, -0.32 to 0.03; t92 = -1.67; P = .10), or accepting (ß, -0.05; SE, 0.08; 95% CI, -0.20 to 0.11; t92 = -0.59; P = .56). There was a significant increase in BOLD percentage signal change in cognitive and attention-regulation regions when reappraising (CBGT = 0.031; MBSR = 0.037) and accepting (CBGT = 0.012; MBSR = 0.077) negative self-beliefs. CBGT and MBSR did not differ in decreased negative emotion and increased reappraisal and acceptance BOLD responses. Reappraisal-associated MBSR (vs CBGT) negative emotions and CBGT (vs MBSR) brain responses were associated with social anxiety symptoms 1 year posttreatment. Conclusions and Relevance: The results of this study suggest that CBGT and MBSR may be effective treatments with long-term benefits for patients with SAD that recruit cognitive and attention-regulation brain networks. Despite contrasting models of therapeutic change, CBT and MBSR may both enhance reappraisal and acceptance emotion regulation strategies.

RESUMO

Do people who have low-quality sleep tend to have more negative affect? This question is of great public interest, and many would assume the answer is "yes." However, previous findings have been mixed, possibly due to differing measures of sleep and affect, or to a failure to separately examine negative affect reactivity and regulation. Across two studies, we assessed adults' perceived sleep quality for at least two weeks and tested their negative affect reactivity and regulation in response to unpleasant pictures (Study 1) or painful thermal stimulation (Study 2) using both self-report and physiological measures. The relationships between perceived sleep quality, on the one hand, and negative affect reactivity and regulation, on the other, were non-significant. Furthermore, a Bayesian approach unanimously favored the null hypothesis. These results suggest that individual differences in perceived sleep quality may not predict negative affect reactivity or regulation across adult individuals.

RESUMO

BACKGROUND: . Cognitive-behavioral therapy and mindfulness-based stress reduction (MBSR) are two prominent evidence-based treatments for social anxiety disorder (SAD). It is not clear, however, whether outcomes of these two treatments are moderated by similar factors. For example, whereas anger suppression and anger expression each predict outcomes in cognitive- behavioral group therapy (CBGT), it is unknown whether they differentially influence outcomes in CBGT versus MBSR. METHODS: . One hundred eight participants with SAD were randomized to CBGT, MBSR or Waitlist (WL). WL participants were later randomized to CBGT or MBSR, and their data were combined with data from those originally randomized to CBGT or MBSR. Anger suppression and anger expression were assessed at pre-treatment, and social anxiety was assessed at pre-treatment, post-treatment, and every 3 months throughout a 12-month follow-up period. RESULTS: . From pre- to post-treatment, higher anger suppression was associated with significantly greater reduction in social anxiety in CBGT compared with MBSR. From post-treatment through follow-up, higher anger expression was associated lesser reduction in social anxiety in MBSR but not in CBGT. LIMITATIONS: . Data are limited by sole reliance on self-report and it is unclear whether these findings generalize beyond group-based interventions. CONCLUSIONS: . Individuals with SAD who are higher in anger suppression and/or expression might be better suited to CBGT than MBSR.

RESUMO

BACKGROUND: Social anxiety disorder (SAD) is characterized by negative self-beliefs (NSBs) that are thought to maintain symptom severity-at least in part-by impairing emotion regulation. Few studies to date have investigated the neural basis of emotion regulation during NSBs in SAD. Moreover, different regulation strategies have not been directly compared, leaving open questions about the generality of emotion regulation deficits in SAD. METHODS: Patients with SAD (n = 113) and healthy control subjects (n = 35) underwent functional magnetic resonance imaging while reacting to NSBs or attempting to downregulate negative emotions occasioned by NSBs using either reappraisal (reinterpreting negative beliefs) or acceptance (nonjudgmentally experiencing thoughts and emotions). Ratings of negative emotion were collected after each trial. RESULTS: When cued to do so, patients with SAD were able to downregulate negative emotions using both reappraisal and acceptance and demonstrated effective recruitment of frontoparietal regulatory regions. Patients with SAD demonstrated greater activation of default mode network and somatomotor regions for the react versus accept contrast. Both groups demonstrated reductions in frontoparietal and default mode network activation during acceptance relative to reappraisal. Greater SAD symptom severity was associated with lower activation in frontoparietal regions during both regulation conditions. CONCLUSIONS: There were no group differences in frontoparietal recruitment during two distinct emotion regulation strategies. However, individual differences in symptom severity within the SAD group were associated with frontoparietal regulation-related activation. Patients with SAD were differentiated from control subjects in default mode network recruitment patterns, suggesting that acceptance may be a useful task condition for revealing altered neural activity in SAD.

RESUMO

BACKGROUND: Depression is a very common condition that impairs functioning and is often untreated. More than 60% of the treatments for depressive disorder are administered in primary care settings by care providers who lack the time and expertise to treat depression. To address this issue, we developed Ascend, a therapist-supported, mobile phone-delivered 8-week intervention administered at the Meru Health Online Clinic in Finland. OBJECTIVE: We conducted two pilot studies to examine the feasibility of the Ascend intervention, specifically, dropout rates, daily practice, weekly group chat use, and changes in depression symptoms. We also explored whether daily practice and weekly group chat use were associated with changes in depression symptoms. METHODS: A total of 117 Finnish adults with elevated depressive symptoms enrolled in Ascend, a program that included daily cognitive behavioral and mindfulness meditation exercises delivered through a mobile phone app, anonymous group chat with other users, and chat/phone access to a licensed therapist. Eight weekly themes were delivered in a fixed, sequential format. Depression symptoms were measured at baseline, every second week during the intervention, immediately after the intervention, and 4 weeks after completion of the intervention. Data were analyzed using intent-to-treat repeated-measures analysis of variance and linear regression models. RESULTS: For studies 1 and 2, we observed dropout rates of 27% and 15%, respectively, decreasing daily practice and group chat use, and decreased depression symptoms from baseline to immediately and 4 weeks after the intervention (P<.001). We found that both more daily practice and chat group use predicted the occurrence of fewer depressive symptoms at 4 weeks postintervention (Study 1: ∆R2=.38, P=.004 and ∆R2=.38, P=.002, respectively; Study 2: ∆R2=.16, P<.001 and ∆R2=.08, P=.002, respectively). CONCLUSIONS: This therapist-supported, mobile phone-delivered treatment for depression is feasible and associated with reduced depression symptoms. Design features that enhance daily practice and group chat use are areas of future investigation. Validation of these results using a controlled study design is needed to establish the evidence base for the Ascend intervention.
