RESUMO

BACKGROUND: A suicide attempt (SA) is a clinically serious action. Researchers have argued that reducing long-term SA risk may be possible, provided that at-risk individuals are identified and receive adequate treatment. Algorithms may accurately identify at-risk individuals. However, the clinical utility of algorithmically estimated long-term SA risk has never been the predominant focus of any study. METHODS: The data of this report stem from CoLaus|PsyCoLaus, a prospective longitudinal study of general community adults from Lausanne, Switzerland. Participants (N = 4,097; Mage = 54 years, range: 36-86; 54% female) were assessed up to four times, starting in 2003, approximately every 4-5 years. Long-term individual SA risk was prospectively predicted, using logistic regression. This algorithm's clinical utility was assessed by net benefit (NB). Clinical utility expresses a tool's benefit after having taken this tool's potential harm into account. Net benefit is obtained, first, by weighing the false positives, e.g., 400 individuals, at the risk threshold, e.g., 1%, using its odds (odds of 1% yields 1/(100-1) = 1/99), then by subtracting the result (400*1/99 = 4.04) from the true positives, e.g., 5 individuals (5-4.04), and by dividing the result (0.96) by the sample size, e.g., 800 (0.96/800). All results are based on 100 internal cross-validations. The predictors used in this study were: lifetime SA, any lifetime mental disorder, sex, and age. RESULTS: SA at any of the three follow-up study assessments was reported by 1.2%. For a range of seven a priori selected threshold probabilities, ranging between 0.5% and 2%, logistic regression showed highest overall NB in 97.4% of all 700 internal cross-validations (100 for each selected threshold probability). CONCLUSION: Despite the strong class imbalance of the outcome (98.8% no, 1.2% yes) and only four predictors, clinical utility was observed. That is, using the logistic regression model for clinical decision making provided the most true positives, without an increase of false positives, compared to all competing decision strategies. Clinical utility is one among several important prerequisites of implementing an algorithm in routine practice, and may possibly guide a clinicians' treatment decision making to reduce long-term individual SA risk. The novel metric NB may become a standard performance measure, because the a priori invested clinical considerations enable clinicians to interpret the results directly.

RESUMO

Individuals diagnosed with major depressive disorder (MDD) and social phobia (SP) have difficulties in social interactions. It is unknown, however, whether such difficulties prevent them from helping others, thereby depriving them of the natural benefits of helping, such as receiving gratitude. Using event sampling methodology (ESM), individuals (MDD, n = 118; SP, n = 47; and control group, n = 119) responded to questions about the frequency of helping, in total at 5333 time points, and their well-being. Contrary to our hypothesis, individuals in the MDD, SP and control group did not differ in their helping frequency. Results did show an association between helping and well-being, such that helping is related to well-being and well-being to helping. Understanding the complex relation of helping others and well-being and how this might be used during therapy and prevention programmes are discussed.

RESUMO

We report on the first investigation of large-scale temporal associations between emotions expressed in online news media and those expressed on social media (Twitter). This issue has received little attention in previous research, although the study of emotions expressed on social media has bloomed owing to its importance in the study of mental health at the population level. Relying on automatically emotion-coded data from almost 1 million online news articles on disease and the coronavirus and more than 6 million tweets, we examined such associations. We found that prior changes in generic emotional categories (positive and negative emotions) in the news on the topic of disease were associated with lagged changes in these categories in tweets. Discrete negative emotions did not robustly feature this pattern. Emotional categories coded in online news stories on the coronavirus generally featured weaker and more disparate lagged associations with emotional categories coded in subsequent tweets.

RESUMO

Exam-related unwanted intrusive thoughts (UITs) and related neutralizing behaviors are common experiences among students. The present study investigated in what ways these UITs and behaviors are analogues to clinical obsessions and compulsions. Twenty-nine students completed three ecological momentary assessment surveys per day over 7 consecutive days, assessing the severity of exam-related UITs and related neutralizing behaviors, obsessive-compulsive (OC) symptoms, anxiety, distress, urge to neutralize, depressed mood, and stress in the week immediately before an exam period. Multilevel analysis demonstrated that the severity of exam-related UITs and related neutralizing behaviors was positively associated with OC symptoms, anxiety, distress, urge to neutralize, and stress but was not related to depressed mood. During the study period, the exam-related UITs occurred on average 7 times, and the related neutralizing behaviors on average 6 times. Overall, they were experienced with mild severity, low distress, and low urge to neutralize. Findings indicate that some aspects of exam-related UITs and related neutralizing behaviors (e.g., association with distress and urge to neutralize) might be analogous to OC symptoms but not all (e.g., no relation to depressed mood). We discuss how research on obsessive-compulsive disorder could benefit from considering exam-related UITs and related behaviors.

RESUMO

BACKGROUND: Compulsive hand washing is one of the most frequent compulsions and includes highly ritualized, repetitive hand motions. Developing an algorithm that can automatically detect compulsive washing with off-the-shelf wearable devices is a first step toward developing more sophisticated sensor-based assessments and micro-interventions that might ultimately supplement cognitive behavioral therapy for obsessive-compulsive disorder (OCD). OBJECTIVE: The main objective was to establish whether enacted compulsive hand washing can be distinguished from routine hand washing. This distinction will inform future research on the development of an algorithm that can automatically detect compulsive hand washing. METHOD: Twenty-one participants were trained individually to wash their hands according to 1 of 5 scripted hand-washing procedures that were based on descriptions of pathological compulsive washes and additionally to wash their hands as they usually would, while wearing a smartwatch. Washes were video recorded to obtain validation data. To generate a baseline model, we opted to extract well-known features only (mean and variance of each sensor axis). We tested four classification models: linear support vector machine (SVM), SVM with radial basis functions, random forest (RF), and naive Bayes (NB). Leave-one-subject-out cross-validation was applied to gather F1, specificity, and sensitivity scores. RESULTS: The best-performing parameters were a classification window duration of 10 s, with a mean-variance feature set calculated from quaternions, rate of turn, and magnetic flux measurements. The detection performance varied with the particular enacted compulsive hand wash (F1 range: 0.65-0.87). Overall, enacted compulsive and routine hand washing could be distinguished with an F1 score of 79% (user independent), a sensitivity of 84%, and a specificity of 30%. CONCLUSIONS: Our analysis of the sensor data demonstrates that enacted compulsive hand washing could be distinguished from routine hand washing with acceptable sensitivity. However, specificity was low. This study is a starting point for a series of follow-ups, including the application in individuals diagnosed with OCD.

RESUMO

Positive affect is associated with alleviating mental and physiological stress responses. As laughter is a common physiological operationalization of positive affect, we investigated whether the effects of experiencing a stressful event on stress symptoms is lessened by frequency and intensity of daily laughter. Using an intensive longitudinal design, we ambulatory assessed the self-reported experience of stressful events, stress symptoms and the frequency as well as the intensity of laughter in university students' daily lives. Our hierarchical ecological momentary assessment data were analyzed with multilevel models. The results support the stress-buffering model of positive affect: We found that the frequency of laughter attenuated the association between stressful events and subsequent stress symptoms. The level of intensity of laughter, however, was found to have no significant effect. Future studies should use additional psychophysiological indicators of stress and straighten out the differential contributions of frequency and intensity of daily laughter.

RESUMO

Traumatic events (TEs) have been associated with suicide attempts (SAs). However, the empirical status of some TEs is inconclusive. This also concerns community adolescents and young adults, known to be a high-risk group for SAs. We examined associations between (a) a range of prior TEs (physical attack, rape/sexual abuse, serious accident, and witnessing somebody else experiencing a TE) and a subsequent SA, and (b) the number of prior TEs and an SA, and (c) we estimated attributable proportions of SAs, in relation to each TE. Over a 10-year period, the Early Developmental Stages of Psychopathology (EDSP) study prospectively assessed community members, aged 14-24 years at baseline. Starting with 3021 subjects, each individual was assessed up to four times. Assessment was based on the Munich-Composite International Diagnostic Interview. Temporal associations were estimated using the Cox model with time-dependent covariates. Attributable proportions were based on the results of the Cox models. All four TEs elevated the risk for a subsequent SA, adjusting for confounders. Highest risk was found for the combined TE rape/sexual abuse. Results showed that 56-90% of SAs could be attributed to TEs in the exposed group; on the population level, attributable proportions ranged between 6.9% and 23.5%. Different TEs have been shown to elevate the risk of an SA in a young community sample. Our results suggest that both health professionals and health policy decision-makers consider specific TEs and the number of prior TEs as risk factors for SAs.

RESUMO

High stress levels can influence sleep quality negatively. If this also applies to anticipatory stress is poorly documented, however. Across insomnia severity levels, this study examined participants' evening levels of (a) anticipatory stress and (b) their skills hypothesized to downregulate the impact of stress, namely openness to internal experiences and continuous engagement in meaningful activities (openness and engagement) and their association with the quality of the subsequent night's sleep. The moderating role of insomnia severity was also tested. We used a quasi-experimental longitudinal design with Experience Sampling Method using smartphones over the course of 1 week (3,976 assessments; 93.2% of prompted queries). Participants recorded their sleep quality, anticipatory stress, and openness and engagement within their daily context. Participants included in the study were diagnosed with major depressive disorder (n = 118), social phobia (n = 47) or belonged to the control group (n = 119). Both anticipatory stress and openness and engagement predicted subsequent sleep quality. Diagnostic group was associated with overall sleep quality, but did not interact with the predictors. These findings were invariant across levels of self-reported insomnia severity. Furthermore, openness and engagement and anticipatory stress did not interact in their effect on sleep quality. The results suggest that both stress reduction and increased openness and engagement are associated with improved subjective sleep quality on a day to day basis, regardless of insomnia severity. Targeting these variables may help improve sleep quality. Future research should disentangle the effects of openness and engagement on anticipatory stress.

RESUMO

OBJECTIVE: The present research systematically investigates the role of recognition experiences at work as a protective factor for burnout. METHOD: In two cross-sectional studies (N = 328 and N = 220) with employees we measured via online questionnaires three forms of recognition (achievement-based social esteem, equality-based respect, and need-based care) from coworkers and supervisors as predictors and burnout among employees as outcome. RESULTS: Using multiple regression analyses, Study 1 provided initial evidence that both supervisor and coworker recognition were negatively associated with employees' burnout. Study 2 further demonstrated that whereas respect experiences were especially crucial for lowering emotional exhaustion, care was primarily linked to reduced depersonalization and esteem to heightened personal accomplishment. CONCLUSION: We discuss how positive recognition experiences can be fostered in organizations in order to buffer the negative effects burnout can cause.

RESUMO

BACKGROUND: The use of machine learning (ML) algorithms to study suicidality has recently been recommended. Our aim was to explore whether ML approaches have the potential to improve the prediction of suicide attempt (SA) risk. Using the epidemiological multiwave prospective-longitudinal Early Developmental Stages of Psychopathology (EDSP) data set, we compared four algorithms-logistic regression, lasso, ridge, and random forest-in predicting a future SA in a community sample of adolescents and young adults. METHODS: The EDSP Study prospectively assessed, over the course of 10 years, adolescents and young adults aged 14-24 years at baseline. Of 3021 subjects, 2797 were eligible for prospective analyses because they participated in at least one of the three follow-up assessments. Sixteen baseline predictors, all selected a priori from the literature, were used to predict follow-up SAs. Model performance was assessed using repeated nested 10-fold cross-validation. As the main measure of predictive performance we used the area under the curve (AUC). RESULTS: The mean AUCs of the four predictive models, logistic regression, lasso, ridge, and random forest, were 0.828, 0.826, 0.829, and 0.824, respectively. CONCLUSIONS: Based on our comparison, each algorithm performed equally well in distinguishing between a future SA case and a non-SA case in community adolescents and young adults. When choosing an algorithm, different considerations, however, such as ease of implementation, might in some instances lead to one algorithm being prioritized over another. Further research and replication studies are required in this regard.

RESUMO

Importance: Suicidal behavior is a leading cause of death among adolescents and young adults. In light of the ideation-to-action framework, the delineation of frequency and temporal characteristics of such behavior during this developmental period is crucial. Objectives: To provide lifetime and 12-month prevalence estimates of suicidal behavior, including ideation, plan, and attempt, in adolescents and young adults of the general population, and to provide information about age at onset, temporal characteristics of suicidal behavior, including duration (number of years between onset and last occurrence) and frequency (number of episodes), and transition patterns across suicidal behaviors. Design, Setting, and Participants: A cross-sectional epidemiological study was conducted in a random community sample of 1180 adolescents and young adults aged 14 to 21 years assessed in 2015 to 2016 in Dresden, Germany. Data analysis was performed from October 2018 to March 2019. Main Outcomes and Measures: Lifetime and 12-month suicidal behavior (ideation, plan, and attempt) were assessed with a standardized diagnostic interview (Munich-Composite International Diagnostic Interview) by trained clinical interviewers. The onset, frequency, and duration of suicidal behavior were assessed by questionnaire. Results: Of the 1180 participants (495 male [weighted percentage, 51.7%]; mean [SD] age, 17.9 [2.3] years), 130 participants (10.7%; 95% CI, 9.0%-12.8%), 65 participants (5.0%; 95% CI, 3.9%-6.5%), and 41 participants (3.4%; 95% CI, 2.4%-4.7%) reported lifetime suicidal ideation, plan, and attempt, respectively. Any lifetime suicidal behavior was reported by 138 participants (11.5%; 95% CI, 9.7%-13.7%). Age-specific cumulative incidence estimates indicated an increase in suicidal behavior during adolescence, starting at age 10 years (<1%), increasing slightly until the age of 12 years (2.2%), and then increasing sharply thereafter until age 20 years (13.5%). There were different patterns among female and male participants for ideation, plan, and attempt, with an overall higher incidence among female participants for ideation (hazard ratio, 1.51; 95% CI, 1.02-2.22; P = .04), for plan (hazard ratio, 3.31; 95% CI, 1.72-6.36; P < .001), and, among those older than 14 years, for attempt (hazard ratio, 3.07; 95% CI, 1.11-8.49; P = .03). Of those with suicidal ideation, 66.0% reported persistent or recurrent ideation over more than 1 year with 75.0% reporting more than 1 episode. Of the participants with lifetime suicidal ideation, 47.0% reported a suicide plan and 23.9% reported a suicide attempt. The transition to suicide plan or attempt occurred mainly in the year of onset of suicidal ideation or plan; of those who transitioned, 74.9% transitioned from ideation to plan, 71.2% transitioned from ideation to attempt, and 85.4% transitioned from plan to attempt in the same year. Conclusions and Relevance: There is an urgent public health need for timely identification of suicidal behavior in adolescents and young adults to terminate persistent or recurrent suicidal tendencies and to interrupt the ideation-to-action transition.

RESUMO

Psychological treatment and assessment necessarily rely on patients' recall. Yet several empirical studies have documented a gap between memory and real-life experience (i.e., memory-experience gap; MeG). We investigated and compared the MeG of sadness, social anxiety, happiness, and physical activity for participants diagnosed with a major depressive disorder (MDD), a social phobia (SP), and participants without such diagnoses (CG). The study included 118 participants diagnosed with a MDD, 47 with a SP, and 119 CG. Using event-sampling methods (ESM), participants were asked via smartphone to report their experiences throughout a week and then to recall those again retrospectively at the end of the study week. Results indicate significant differences in the MeG with respect to the experience that was salient to them (e.g., MDD group - sadness; SP group - social anxiety; CG group - happiness). Furthermore, all groups showed a MeG for physical activity and, the results indicate significant group differences in the magnitude of the MeGs. This study demonstrated the presence of a MeG in individuals in a MDD, SP, and CG group and in positive and negative affective experiences. Differential patterns across the samples contribute to a better understanding of this gap and its implications.

RESUMO

Background/Objective: Lower levels in well-being have been observed in individuals with Major Depression (MDD) and Social Phobia (SP), but well-planned direct comparisons with control individuals, not suffering from a mental disorder, are lacking. Furthermore, MDD is highly comorbid with anxiety disorders, and SP with depressive disorders. This study is among the first to examine differences in well-being in individuals with a clinical diagnosis of MDD or SP compared to individuals with no such diagnosis and to test differences in well-being within the combined diagnostic categories respective with and without anxiety-depressive comorbidity. Method: Participants were 119 individuals with a diagnosis of MDD, 47 SP and 118 controls. Results: Results revealed that overall well-being as well as emotional, psychological, and social well-being were lower in the MDD and SP group compared to the control group. Individuals with comorbidity reported lower well-being than individuals without comorbidity. Conclusions: These findings have clinical implications as presence of comorbidity may require a different therapeutic approach than with no comorbidity


Antecedentes/Objetivo: Se han observado niveles bajos de bienestar en individuos con depresión grave (DG) y fobia social (FS). Sin embargo, las comparaciones directas planificadas con individuos controles que no padecen ningún trastorno mental son escasas. Además, la DG se suele presentar con trastornos de ansiedad, y la FS con trastornos depresivos. Este estudio es uno de los primeros en examinar las diferencias entre el bienestar en individuos con un diagnóstico clínico de DG o FS, comparados con individuos sin dicho diagnóstico y en comprobar las diferencias de bienestar dentro de cada categoría de diagnóstico en realación a individuos con y sin comorbilidad. Método: Participaron 119 individuos con un diagnóstico de DG, con base en la SCID, 47 con FS y 118 controles. Resultados: Los resultados revelaron que el bienestar general, así como el bienestar emocional, psicológico y social eran inferiores en el grupo de DG y FS en comparación con el grupo control. Los individuos con comorbilidad informaron un menor bienestar que los individuos sin comorbilidad. Conclusiones: Estos resultados tienen repercusión clínica, pues la presencia de la comorbilidad puede requerir un acercamiento terapéutico diferente al de un único trastorno

RESUMO

BACKGROUND: Comorbidity of obsessive-compulsive disorder (OCD) with other mental disorders has been demonstrated repeatedly. Few longitudinal studies, however, have evaluated the temporal association of prior OCD and subsequent mental disorders across the age period of highest risk for first onset of mental disorders. We examined associations between prior OCD and a broad range of subsequent mental disorders and simulated proportions of new onsets of mental disorders that could potentially be attributed to prior OCD, assuming a causal relationship. METHODS: Data from 3,021 14- to 24-year-old community subjects were prospectively collected for up to 10 years. DSM-IV OCD and other DSM-IV mental disorders were assessed with the Munich-Composite International Diagnostic Interview. We used adjusted time-dependent proportional hazard models to estimate the temporal associations of prior OCD with subsequent mental disorders. RESULTS: Prior OCD was associated with an increased risk of bipolar disorders (BIP; [hazard ratio, HR = 6.9, 95% confidence interval, CI, (2.8,17.3)], bulimia nervosa [HR = 6.8 (1.3,36.6)], dysthymia [HR = 4.4 (2.1,9.0)], generalized anxiety disorder (GAD; [HR = 3.4 (1.1,10.9)], and social phobia [HR = 2.9 (1.1,7.7)]). Of these outcome disorders, between 65 and 85% could be attributed to OCD in the exposed group, whereas between 1.5 and 7.7% could be attributed to OCD in the total sample. CONCLUSIONS: This study provides strong evidence that prior OCD is associated with an increased risk of subsequent onset of BIP, bulimia nervosa, dysthymia, GAD, and social phobia among adolescents and young adults. Future studies should evaluate if early treatment of OCD can prevent the onset of these subsequent mental disorders.

RESUMO

Adolescents and young adults represent the high-risk group for first onset of both DSM-IV mental disorders and lifetime suicide attempt (SA). Yet few studies have evaluated the temporal association of prior mental disorders and subsequent first SA in a young community sample. We examined (a) such associations using a broad range of specific DSM-IV mental disorders, (b) the risk of experiencing the outcome due to prior comorbidity, and (c) the proportion of SAs that could be attributed to prior disorders. During a 10-year prospective study, data were gathered from 3021 community subjects, 14-24 years of age at baseline. DSM-IV disorders and SA were assessed with the Munich-Composite International Diagnostic Interview. Cox models with time-dependent covariates were used to estimate the temporal associations of prior mental disorders with subsequent first SA. Most prior mental disorders showed elevated risk for subsequent first SA. Highest risks were associated with posttraumatic stress disorder (PTSD), dysthymia, and nicotine dependence. Comorbidity elevated the risk for subsequent first SA, and the more disorders a subject had, the higher the risk for first SA. More than 90% of SAs in the exposed group could be attributed to PTSD, and over 30% of SAs in the total sample could be attributed to specific phobia. Several DSM-IV disorders increase the risk for first SA in adolescents and young adults. Several promising early intervention targets were observed, e.g., specific phobia, nicotine dependence, dysthymia, and whether a young person is burdened with comorbid mental disorders.

RESUMO

Symptom fluctuations and the dynamic contexts provoking these are poorly understood. This deficit is compounded by people's limited ability to accurately report about such dimensions in retrospect. Utilizing the advantages of experience sampling methodology (ESM), this study rigorously describes and tests proximal environmental, neurobiological and psychological factors associated with symptoms and mood states. Participants were assigned to three diagnostic groups: Major Depressive Disorder (MDD; n = 118), Social Phobia (SP; n = 47), or a Control Group without SP or MDD (CG; n = 119). Laboratory assessments included cognitive abilities, memory, constructs, and brain derived neurotrophic factor (BDNF). ESM lasted seven days, with six assessments per day covering symptoms, affect, daily events, social interactions, post-event processing, well-being, etc. Morning cortisol and actigraphy were also assessed during ESM. Thereafter, participants provided subjective retrospective recall estimates of the emotions they reported during ESM. The multi-level data of >10,000 observations will allow for thorough examination of fluctuations of psychopathology and well-being in two highly prevalent disorders. Using two clinical groups and a non-affected control group, the clinical specificity versus generalizability of processes can be directly tested, thus providing stimulating information about the overlap and differences between anxiety and affective disorders. This research informs about the development, fluctuation, and maintaining factors of emotions and symptoms and examines the accuracy with which participants recall these dimensions.

RESUMO

Inspired by philosophical reasoning about the connection between equality and freedom, we examined whether experiences of (equality-based) respect increase perceived autonomy. This link was tested with generalized experiences of respect and autonomy people make in their daily lives (Study 1) and with more specific experiences of employees at the workplace (Study 2). In both studies, respect strongly and independently contributed to perceived autonomy over and above other forms of social recognition (need-based care and achievement-based social esteem) and further affected (life/work) satisfaction. Study 3 experimentally confirmed the hypothesized causal influence of respect on perceived autonomy and demonstrated that this effect further translates into social cooperation. The respect-cooperation link was simultaneously mediated by perceived autonomy and superordinate collective identification. We discuss how the recognition approach, which differentiates between respect, care, and social esteem, can enrich research on autonomy.

RESUMO

BACKGROUND: The role of specific phobia as a potentially important psychopathological precursor condition to more severe mental disorders is understudied. We examined the prospective-longitudinal association of early childhood/adolescent phobia with subsequent mental disorders and the proportion of outcome disease incidence attributable to specific phobia simultaneously for a broad range of disorders. METHODS: N = 2210 14- to 24-year-old community subjects were followed up for 10 years. DSM-IV-specific phobia as exposure and a broad range of DSM-IV mental disorders as outcomes were assessed with the DSM-IV/M-CIDI. Logistic regressions, adjusting for confounders, were used to estimate the associations of specific phobia with the subsequent onset of outcome disorders. RESULTS: Baseline specific phobia predicted the subsequent first onset of anxiety disorders [panic disorder: risk ratio (RR) = 4.38, 95% confidence interval (2.34, 8.21); generalized anxiety disorder: RR = 4.10 (2.19, 7.69); posttraumatic stress disorder: RR = 2.15 (1.13, 4.10); obsessive-compulsive disorder: RR = 3.79 (1.63, 8.82)], affective disorders [major depression: RR = 1.54 (1.16, 2.03); bipolar disorder: RR = 2.20 (1.10, 4.41); dysthymia: RR = 2.75 (1.48, 5.11)], pain disorder: RR = 1.52 (1.14, 2.02), and eating disorders: RR = 2.27 (1.14, 4.51). Population attributable fractions (PAFs; i.e., proportion of outcome disease incidence in the total population attributable to specific phobia) were highest for panic disorder (PAF = 33.93), generalized anxiety disorder (PAF = 32.3), and obsessive-compulsive disorders (PAF = 30.2). CONCLUSION: This study provides strong evidence that specific phobia is an early onset disorder predicting the subsequent onset of a range of disorders. Future studies should examine the underlying mechanisms and the potential of using specific phobia as a target for prevention of subsequent psychopathology.
