RESUMO

BACKGROUND: Despite negative associations of trait resilience with depression and anxiety symptoms, the mechanisms by which resilience may buffer against these symptoms remain underexplored. This study investigated emotion regulation difficulties as a potential link in the relationship between trait resilience and depression and anxiety severity in psychiatric outpatients (N = 353). METHODS: Participants diagnosed with primary depression or anxiety disorders were evaluated prior to treatment initiation with the Connor-Davidson Resilience Scale, Difficulties in Emotion Regulation Scale (DERS), Clinically Useful Depression Outcome Scale (CUDOS), and Clinically Useful Anxiety Outcome Scale (CUXOS). RESULTS: In the depression sample, the effect of resilience on CUDOS scores was fully mediated by total DERS scores. In the anxiety sample, the effect of resilience on CUXOS scores was partially mediated by total DERS scores. Exploratory parallel mediation analyses showed only the DERS subscale strategies had a significant effect on CUDOS scores, while only goals had a significant effect on CUXOS scores. CONCLUSIONS: Emotion regulation difficulties are a mediator of trait resilience in psychiatric outpatients. For patients seeking treatment for depression, difficulties with accessing emotion regulation strategies may be particularly relevant, while difficulties meeting one's goals may be most relevant for patients seeking treatment for anxiety.

RESUMO

INTRODUCTION: Interoception refers to awareness, interpretation, and integration of sensations in the body. While interoceptive accuracy has long been regarded as a core component of emotional experience, less is known about the relationship of interoceptive accuracy and related facets of interoception to emotion regulation deficits. This study explores how interoceptive accuracy and interoceptive sensibility relate to emotion regulation in a non-clinical sample. METHODS: Undergraduate participants completed a heartbeat perception task and the Multidimensional Assessment of Interoceptive Awareness (Noticing and Body Listening sub-scales), and rated their confidence in performance on the heartbeat perception task. Participants also completed self-report measures of emotional awareness and regulation (Profile of Emotional Competence, intrapersonal emotion identification and emotion regulation sub-scales), and rated their use of different coping strategies (Brief COPE). RESULTS: Noticing predicted emotion identification, emotion regulation, and the use of adaptive but not maladaptive coping strategies. Heartbeat perception accuracy did not significantly contribute to the prediction of any outcome variables. DISCUSSION: Future work is needed to extend these findings to clinical populations. The results from this study support the use of interoceptive training interventions to promote emotional wellbeing.

RESUMO

Little is known about help-seeking for depression among Jordanian adolescents who are a vulnerable population with high rates of depressive symptoms and few mental health services. The purpose of this study was to (1) explore Jordanian adolescents' helpseeking intentions for depression and (2) examine whether depression stigma, depression severity, or their interaction are associated with Jordanian adolescents' willingness to seek help for depression and the type of treatment they would seek. In collaboration with the Jordanian Ministry of Education, we conducted a nationally representative, school-based survey of adolescents aged 12-17 years ( N = 2,349). One fourth of the adolescents reported they would not seek professional help for depression, and those respondents had higher average depression scores. Among those adolescents willing to seek help, the most likely sources included family member (57%), school counselor (46%), psychiatrist (43%), religious leader (39%), and general health practitioner (28%). Lower stigma scores were associated with greater likelihood to seek psychotherapy or visit a psychiatrist, while higher stigma scores were associated with increased likelihood to seek help from a school counselor or a family member. Jordanian adolescents experience significant barriers to seeking professional help for depression. However, even among adolescents with greater depression severity and depression stigma, school counselors were identified as a key resource for help. These findings suggest that school-based interventions may fill a critical service need for adolescents with depression and other mental health problems. School nurses should be leveraged along with counselors to address mental health issues in this vulnerable population.

RESUMO

BACKGROUND: The lack of research regarding the current profile of adolescent depression in the Arab countries in general, and Jordan in particular, makes it difficult to design, implement, and disseminate effective interventions to improve the prevention, diagnosis, and treatment of adolescent depression in the region. The purpose of this study was to estimate a national prevalence of depressive symptoms among adolescents in Jordan, and to identify characteristics associated with severity of depression. METHODS: A descriptive, cross-sectional, nationally representative school survey was utilized. A total of 2,349 Jordanian adolescents aged 12-17 completed and returned the survey packets, which included the Beck Depression Inventory-II and measures of sociodemographics and health history. Participants represented all three regions in the country, with 34% from the northern (suburban) region, 43% from the central (urban) region, and 23% from the southern (rural) region. RESULTS: The majority of the adolescents were females (59%) and 15-17 years old (67%). Almost 14% reported having at least one chronic health problem, 15% reported having a mental health problem, 25% reported having academic difficulties, 8% reported that they had received a psychiatric diagnosis, and 22% reported that they had sought psychological help at some point in the past. The mean total depression score was 16.3 (SD = 11.2, 95% CI = 15.8-16.7), with 34% of the sample reporting moderate to severe depression. Depression was significantly higher among respondents who were female, ages 14-15 years, and living in families with low monthly incomes; and who reported having a chronic health problem, mental health problem, learning difficulty, a psychiatric diagnosis and/or seeking previous psychological help. CONCLUSIONS: Our findings should serve as an alarm, particularly given that rates of depression in the Arab countries are expected to increase rapidly in the context of the Arab Spring. Healthcare providers, researchers, and educators should focus attention on developing effective and culturally appropriate screening, prevention, and intervention approaches using evidence-based guidelines to promote Jordanian adolescent mental health, particularly for depression.

RESUMO

The influence of gender and other individual and context characteristics on the prevalence and severity of depressive symptoms among Jordanian adolescents remains unclear. The aims of the current study were to: (a) characterize depressive symptoms profiles for Jordanian adolescents; and (b) examine gender differences in the type, severity, and correlates of depressive symptoms. Cross-sectional data were collected from 2,349 Jordanian adolescents ages 12 to 17 using a nationally representative school survey. The Beck Depression Inventory-II was used to assess the presence and severity of depressive symptoms. Female adolescents had significantly higher mean depression scores (17.9 [SD = 11.6], 95% confidence interval [CI] [17.3, 18.5]) than their male counterparts (13.8 [SD = 10.2], 95% CI [13.2, 14.5]). Approximately 41% of girls and 26% of boys reported scores indicating moderate to severe depression. Sex differences and socially constructed gender differences need to be adequately considered in the planning and delivery of mental health care for adolescent depression. If the risk for depression is gender-specific, prevention strategies cannot be gender-neutral. [Journal of Psychosocial Nursing and Mental Health Services, 56(2), 44-55.].

RESUMO

BACKGROUND: In Arab communities, the selection, utilization, and attitudes towards mental health services are substantially affected by existing mental illness stigma. However, little is known about how the stigma of depression manifests among Arab adolescents, which makes it difficult to design, implement, and disseminate effective anti-stigma interventions for this vulnerable population. Therefore, the purpose of this study was to determine levels of depression stigma among Arab adolescents. The specific aims were to (1) describe the severity of personal and perceived depression stigma among Arab adolescents and its relationship to severity of depression, and (2) determine characteristics associated with severity of depression stigma among Arab adolescents. METHODS: This study was conducted in Jordan, a Middle Eastern Arab country. A nationally representative, school-based survey was utilized. A total of 2349 Jordanian adolescents aged 12-17 completed and returned the survey packets, which included measures on individual characteristics, depression severity, and depression stigma. RESULTS: The majority of the adolescents (88%) reported scores indicating moderate to high depression stigma. Adolescents reported higher rates of perceived stigma than personal stigma. Depression stigma was not significantly associated with severity of depression, but with adolescent's sex, age, region of residence, parents' education, and history of mental health problem. CONCLUSIONS: This is the first Arab study to isolate the influence of adolescent depression and personal characteristics on personal and perceived depression stigmas, and highlight the presence of these distinctions early in adolescence. Such distinction can inform the design and implementation of policies and interventions to reduce both personal and perceived stigma. The study provides important recommendations on when, how, and why to utilize school settings for anti-depression stigma interventions.

RESUMO

OBJECTIVES: The present study compares the effectiveness of two strategies, reappraisal and distraction, in reducing negative affect in older adults induced by focusing on personally relevant negative events and stressors. PARTICIPANTS: 30 adults with major depressive disorger (MDD) and 40 never-depressed (ND) comparison participants ages 60 years and over (mean age = 69.7 years). DESIGN AND MEASUREMENTS: Participants underwent three affect induction trials, each followed by a different emotion regulation strategy: distraction, reappraisal, and a no-instruction control condition. Self-reported affect was recorded pre- and post-affect induction, and at one-minute intervals during regulation. RESULTS: Across groups, participants reported greater reductions in negative affect with distraction than reappraisal or the no-instruction control condition. An interaction between group and regulation condition indicated that distraction was more effective in reducing negative affect in the MDD group than the ND group. CONCLUSIONS: These results suggest that distraction is an especially effective strategy for reducing negative affect in older adults with MDD. Finding ways to incorporate distraction skills into psychotherapeutic interventions for late-life MDD may improve their effectiveness, especially for short-term improvement of affect following rumination.

RESUMO

BACKGROUND: Anhedonia is a transdiagnostic symptom often resistant to treatment. The identification of biomarkers sensitive to anhedonia treatment will aid in the evaluation of novel anhedonia interventions. METHODS: This is an exploratory analysis of changes in subcortical brain volumes accompanying psychotherapy in a transdiagnostic anhedonic sample using ultra-high field (7-Tesla) MRI. Outpatients with clinically impairing anhedonia (n = 116) received Behavioral Activation Treatment for Anhedonia, a novel psychotherapy, or Mindfulness-Based Cognitive Therapy (ClinicalTrials.gov Identifiers NCT02874534 and NCT04036136). Subcortical brain volumes were estimated via the MultisegPipeline, and regions of interest were the amygdala, caudate nucleus, hippocampus, pallidum, putamen, and thalamus. Bivariate mixed effects models estimated pre-treatment relations between anhedonia severity and subcortical brain volumes, change over time in subcortical brain volumes, and associations between changes in subcortical brain volumes and changes in anhedonia symptoms. RESULTS: As reported previously (Cernasov et al., 2023), both forms of psychotherapy resulted in equivalent and significant reductions in anhedonia symptoms. Pre-treatment anhedonia severity and subcortical brain volumes were not related. No changes in subcortical brain volumes were observed over the course of treatment. Additionally, no relations were observed between changes in subcortical brain volumes and changes in anhedonia severity over the course of treatment. LIMITATIONS: This trial included a modest sample size and did not have a waitlist-control condition or a non-anhedonic comparison group. CONCLUSIONS: In this exploratory analysis, psychotherapy for anhedonia was not accompanied by changes in subcortical brain volumes, suggesting that subcortical brain volumes may not be a candidate biomarker sensitive to response to psychotherapy.

RESUMO

OBJECTIVES: To assess the relationship of multiple domains and facets of the five-factor model of personality with presence, onset, and severity of late-life depression. DESIGN: Cross-sectional analysis of depression status, and age of onset. Retrospective analysis of baseline severity. Longitudinal analysis of severity after 3 and 12 months of psychiatric treatment. SETTING: Private university-affiliated medical center in the Southeastern United States. PARTICIPANTS: One hundred twelve psychiatric patients with a current episode of unipolar major depression, and 104 nondepressed comparison subjects, age 60 and older (mean: 70, SD: 6). MEASUREMENTS: Revised NEO Personality Inventory, Diagnostic Interview Schedule, and Montgomery-Åsberg Depression Rating Scale. RESULTS: Binary logistic regression found that depression was related to higher neuroticism (and all its facets) and to lower extraversion (and facets of assertiveness, activity, and positive emotionality) and conscientiousness (and facets of competence, order, dutifulness, and self-discipline). Multinomial logistic regression found some of these relationships held only for depression with onset before age 50 (hostility, self-consciousness, extraversion, assertiveness, positive emotions, order, and dutifulness). Linear regression found that personality was unrelated to depression severity at the beginning of treatment, but improvement after 3 months was related to lower neuroticism (and facets depressiveness and stress-vulnerability) and higher warmth and competence. Improvement after 12 months was related to lower neuroticism, depressiveness, and stress-vulnerability. CONCLUSIONS: Specific personality facets are related with depression and treatment outcomes. Screening for certain personality traits at the start of treatment may help identify patients at risk of worse response to treatment after 3 months.

RESUMO

BACKGROUND: Neuroticism is a psychological construct that includes tendency to exhibit negative affect (NA), having poor stress tolerance and being at risk for depression and anxiety disorders. The consequences of neuroticism in the elderly adults are understudied. We hypothesized that older depressed patients with comorbid neuroticism at baseline would have worse mood and cognitive outcomes compared with older depressed patients without neuroticism. METHODS: One hundred and ten older depressed adults completed baseline self-reports of depression and the NEO-Personality Inventory as a measure of neuroticism, were administered a battery of cognitive tests annually and were seen by a study psychiatrist who assessed patients using the Montgomery Åsberg Depression Rating Scale (MADRS) and treated patients with antidepressants using an established treatment guideline. Patients were followed as clinically indicated for up to three years. We measured remission (defined as MADRS score ≤ 6) rates at one year as a categorical outcome. In addition, we used Cox proportional hazard models to examine the relationship between neuroticism and change in MADRS and cognitive score over time. RESULTS: Non-remitters (30%) at one year had higher scores in total neuroticism (TN), vulnerability to stress (VS), and NA. Over three years, time to achieve remission was associated with higher TN, higher VS, and greater NA. In analyses controlling for baseline cognitive score, age, sex, and education, VS was associated with baseline to two-year change in cognition. CONCLUSIONS: Presence of neuroticism in older depressed patients treated with medication is associated with poor mood outcomes and may indicate increased risk of cognitive decline.

RESUMO

This study assessed the relationship between modifiable psychological variables and depression, anxiety, and posttraumatic growth in women experiencing infertility. U.S. women (N = 457) who identified as experiencing infertility completed standardized self-report measures of mindfulness, self-compassion, positive affect, intolerance of uncertainty, relationship satisfaction, experiential avoidance, depression, anxiety, and posttraumatic growth. Clinical and demographic characteristics (age, duration trying to conceive, miscarriage, and childlessness) did not predict depression or anxiety. Lower positive affect and higher experiential avoidance were associated with depression and anxiety. Lower self-compassion was associated with depression; higher intolerance of uncertainty was associated with anxiety. There were indirect effects of mindfulness on anxiety and depression via these variables. Future research should explore whether intervening on these factors reduces depressive and anxiety symptoms. Promoting mindfulness may have beneficial effects on symptoms via its downstream effects on multiple coping variables. Counterintuitively, posttraumatic growth was associated with higher intolerance of uncertainty and experiential avoidance.

RESUMO

BACKGROUND: Anhedonia is hypothesized to be associated with blunted mesocorticolimbic dopamine (DA) functioning in samples with major depressive disorder. The purpose of this study was to examine linkages between striatal DA, reward circuitry functioning, anhedonia, and, in an exploratory fashion, self-reported stress, in a transdiagnostic anhedonic sample. METHODS: Participants with (n = 25) and without (n = 12) clinically impairing anhedonia completed a reward-processing task during simultaneous positron emission tomography and magnetic resonance (PET-MR) imaging with [11C]raclopride, a DA D2/D3 receptor antagonist that selectively binds to striatal DA receptors. RESULTS: Relative to controls, the anhedonia group exhibited decreased task-related DA release in the left putamen, caudate, and nucleus accumbens and right putamen and pallidum. There were no group differences in task-related brain activation (fMRI) during reward processing after correcting for multiple comparisons. General functional connectivity (GFC) findings revealed blunted fMRI connectivity between PET-derived striatal seeds and target regions in the anhedonia group. Associations were identified between anhedonia severity and the magnitude of task-related DA release to rewards in the left putamen, but not mesocorticolimbic GFC. CONCLUSIONS: Results provide evidence for reduced striatal DA functioning during reward processing and blunted mesocorticolimbic network functional connectivity in a transdiagnostic sample with clinically significant anhedonia.

RESUMO

BACKGROUND: Studies of individuals who do not meet criteria for major depressive disorder (MDD) but with subclinical levels of depressive symptoms may aid in the identification of neurofunctional abnormalities that possibly precede and predict the development of MDD. The purpose of this study was to evaluate relations between subclinical levels of depressive symptoms and neural activation patterns during tasks previously shown to differentiate individuals with and without MDD. METHODS: Functional magnetic resonance imaging (fMRI) was used to assess neural activations during active emotion regulation, a resting state scan, and reward processing. Participants were twelve females with a range of depressive symptoms who did not meet criteria for MDD. RESULTS: Increased depressive symptom severity predicted (1) decreased left midfrontal gyrus activation during reappraisal of sad stimuli; (2) increased right midfrontal gyrus activation during distraction from sad stimuli; (3) increased functional connectivity between a precuneus seed region and left orbitofrontal cortex during a resting state scan; and (4) increased paracingulate activation during non-win outcomes during a reward-processing task. CONCLUSIONS: These pilot data shed light on relations between subclinical levels of depressive symptoms in the absence of a formal MDD diagnosis and neural activation patterns. Future studies will be needed to test the utility of these activation patterns for predicting MDD onset in at-risk samples.

RESUMO

BACKGROUND: Transdiagnostic clinical emotional dysregulation is a key component of many mental health disorders and offers an avenue to address multiple disorders with one transdiagnostic treatment. In the current study, we pilot an intervention that combines a one-time teaching and practice of cognitive restructuring (CR) with repetitive transcranial magnetic stimulation (rTMS), targeted based on functional magnetic resonance imaging (fMRI). METHODS: Thirty-seven clinical adults who self-reported high emotional dysregulation were enrolled in this randomized, double-blind, placebo-controlled trial. fMRI was collected as participants were reminded of lifetime stressors and asked to downregulate their distress using CR tactics. fMRI BOLD data were analyzed to identify the cluster of voxels within the left dorsolateral prefrontal cortex (dlPFC) with the highest activation when participants attempted to downregulate, versus passively remember, distressing memories. Participants underwent active or sham rTMS (10 Hz) over the left dlPFC target while practicing CR following emotional induction using recent autobiographical stressors. RESULTS: Receiving active versus sham rTMS led to significantly higher high frequency heart rate variability during regulation, lower regulation duration during the intervention, and higher likelihood to use CR during the week following the intervention. There were no differences between conditions when administering neurostimulation alone without the CR skill and compared to sham. Participants in the sham versus active condition experienced less distress the week after the intervention. There were no differences between conditions at the one-month follow up. CONCLUSION: This study demonstrated that combining active rTMS with emotion regulation training for one session significantly enhances emotion regulation and augments the impact of training for as long as a week. These findings are a promising step towards a combined intervention for transdiagnostic emotion dysregulation.

RESUMO

Anhedonia, the loss of interest or pleasure in normally rewarding activities, is a hallmark feature of unipolar Major Depressive Disorder (MDD). A growing body of literature has identified frontostriatal dysfunction during reward anticipation and outcomes in MDD. However, no study to date has directly compared responses to different types of rewards such as pleasant images and monetary rewards in MDD. To investigate the neural responses to monetary and pleasant image rewards in MDD, a modified Monetary Incentive Delay task was used during functional magnetic resonance imaging to assess neural responses during anticipation and receipt of monetary and pleasant image rewards. Participants included nine adults with MDD and 13 affectively healthy controls. The MDD group showed lower activation than controls when anticipating monetary rewards in right orbitofrontal cortex and subcallosal cortex, and when anticipating pleasant image rewards in paracingulate and supplementary motor cortex. The MDD group had relatively greater activation in right putamen when anticipating monetary versus pleasant image rewards, relative to the control group. Results suggest reduced reward network activation in MDD when anticipating rewards, as well as relatively greater hypoactivation to pleasant image than monetary rewards.

RESUMO

Mindfulness-Based Stress Reduction is a secular behavioral medicine program that has roots in meditative spiritual practices. Thus, spirituality may partly explain Mindfulness-Based Stress Reduction outcomes. Participants (N = 279; M (SD) age = 45(12); 75% women) completed an online survey before and after an 8-week Mindfulness-Based Stress Reduction program. Structural equation modeling was used to test the hypothesis that, following Mindfulness-Based Stress Reduction, the relationship between enhanced mindfulness and improved health-related quality of life is mediated by increased daily spiritual experiences. Changes in both spirituality and mindfulness were significantly related to improvement in mental health. Although the initial mediation hypothesis was not supported, an alternate model suggested that enhanced mindfulness partly mediated the association between increased daily spiritual experiences and improved mental health-related quality of life (indirect effect: ß = 0.07, P = 0.017). Effects on physical health-related quality of life were not significant. Findings suggest a novel mechanism by which increased daily spiritual experiences following Mindfulness-Based Stress Reduction may partially explain improved mental health as a function of greater mindfulness.

RESUMO

Although mindfulness-based stress reduction (MBSR) can improve health and well-being, less is known about factors that predict outcomes. This prospective observational study examined gender and baseline anxiety and sleep quality as predictors of change in emotion regulation and stress symptoms following an 8-week MBSR program. Women and men reported similar improvement in stress symptoms and cognitive reappraisal, whereas men improved more in emotion suppression. Individuals with higher anxiety and worse sleep pre-treatment benefited most in terms of decreased stress. Evaluating pre-treatment characteristics could help determine optimal candidates for MBSR training, and could optimize outcomes for both women and men.

RESUMO

BACKGROUND: The Sweet Taste Test (STT) measures hedonic responses to sweet tastes and has been linked to both alcoholism and to a family history of alcoholism. However, STT response profiles in unipolar major depressive disorder (MDD), a disorder characterized by anhedonia, have been minimally investigated. METHODS: Twelve adults with and 15 adults without MDD participated in two identical STT assessments separated by approximately 12 weeks. Between assessments, MDD outpatients received Behavioral Activation Therapy for Depression, a psychotherapy modality designed to increase engagement with rewarding stimuli and reduce avoidance behaviors. Primary-dependent measures included sensitivity to sucrose, hedonic response to sucrose, and designation as a Sweet-Liker or Sweet-Disliker. RESULTS: A total of 75% of adults with MDD were treatment responders. There were no significant differences in STT response profiles between groups overall or at either timepoint. Furthermore, STT profiles of MDD participants did not differ after psychotherapy, relative to baseline. CONCLUSIONS: Findings suggest that although anhedonia is a symptom of MDD, the disorder is not characterized by altered responses to sweet tastes. Implications and future directions are discussed.

RESUMO

Behavioral Activation (BA) is a contemporary third-wave psychosocial treatment approach that emphasizes helping individuals become more active in ways that are meaningful to them as a means of improving mood and quality of life. BA has been designated as a well-established, validated treatment for depression by the American Psychological Association following several decades of accumulated empirical support demonstrating that BA techniques successfully reduce depression symptoms and produce other desirable outcomes across a variety of populations and contexts. The purported mechanism of change underlying BA treatment lies in increasing activation, which in turn increases contact with positive reinforcement thereby reversing the cycle of depression. Current studies are further investigating how increasing activation and subsequent contact with mood reinforcers can influence mood and behavior. Specifically, there is growing evidence that BA modifies function of reward-related networks in the brain, and that these changes are associated with clinical improvement. Herein, we provide a brief history of BA, describe the primary components of BA treatment, and describe BA's purported mechanisms of change at behavioral, neural, and subjective activation levels. We present limitations as well as gaps in the current state of knowledge regarding mechanisms of action of BA.
