Time-Varying Network Models for the Temporal Dynamics of Depressive Symptomatology in Patients With Depressive Disorders: Secondary Analysis of Longitudinal Observational Data.

BACKGROUND: As depression is highly heterogenous, an increasing number of studies investigate person-specific associations of depressive symptoms in longitudinal data. However, most studies in this area of research conceptualize symptom interrelations to be static and time invariant, which may lead to important temporal features of the disorder being missed. OBJECTIVE: To reveal the dynamic nature of depression, we aimed to use a recently developed technique to investigate whether and how associations among depressive symptoms change over time. METHODS: Using daily data (mean length 274, SD 82 d) of 20 participants with depression, we modeled idiographic associations among depressive symptoms, rumination, sleep, and quantity and quality of social contacts as dynamic networks using time-varying vector autoregressive models. RESULTS: The resulting models showed marked interindividual and intraindividual differences. For some participants, associations among variables changed in the span of some weeks, whereas they stayed stable over months for others. Our results further indicated nonstationarity in all participants. CONCLUSIONS: Idiographic symptom networks can provide insights into the temporal course of mental disorders and open new avenues of research for the study of the development and stability of psychopathological processes.

Changes in the ability to correctly identify schizophrenia and depression: results from general population surveys in Germany over 30 years.

PURPOSE: This study aims to examine time trends in the ability to correctly identify schizophrenia and major depression within the German general population from 1990 to 2020, as an indicator of changing mental health literacy (MHL). Additionally, we investigated shifts in the use of stigmatizing language. METHODS: Our analysis is based on four waves of representative population surveys in Germany in 1990/1993 (West Germany: N = 2044, East Germany: N = 1563), 2001 (N = 5025), 2011 (N = 2455), and 2020 (N = 3042) using identical methodology. Respondents were presented with an unlabelled case vignette describing a person who exhibited symptoms of either schizophrenia or major depression. Participants were then asked to name the problem described in the vignette using an open-ended question. RESULTS: From 1990/1993 to 2020, correct identification of schizophrenia increased from 18% to 34% and from 27% to 46% for major depression. However, derogatory labels remained constant throughout all survey waves, particularly for schizophrenia (19% in 1990/1993 and 18% in 2020). For depression, more trivializing and potentially devaluing statements were recorded. CONCLUSION: Despite the increasing use of psychiatric terminology among the general population, the persistence of derogatory labels suggests that improved MHL, reflected in higher recognition rates, may not automatically translate into a reduction in stigmatizing language. With depression, a normalization and trivialization of a severe illness could pose new challenges to people with major depression. Dedicated efforts to combat the stigma of severe mental illness are still needed.

Lifestyle causal beliefs are associated with higher personal and perceived stigma regarding depressive disorders: results from a representative population survey.

BACKGROUND: Depression is a prevalent and severe disorder associated with considerable stigma. This stigma contributes to the suffering and impedes help seeking behaviour of those affected. Stigma can be influenced by causal beliefs about depression and personal contact with people suffering from depression. The aim of this study was to investigate (1) the associations between beliefs about the aetiology of depression and personal / perceived stigma, as well as (2) a possible moderating effect of personal contact with people with depression on these associations. METHODS: Stigma, causal beliefs, and contact with depression were assessed in a representative online survey among German adults (N = 5,000). Multiple regression analyses were performed with contact levels (unaffected vs. personally affected (diagnosed) vs. personally affected (undiagnosed) vs. affected by relatives with depression vs. persons who treat depression) and causal beliefs (biogenetic vs. psychosocial vs. lifestyle) as predictor variables for personal and perceived stigma as dependent variables. RESULTS: Higher personal stigma was associated with lifestyle causal beliefs (p < .001, f² = 0.07), lower personal stigma with biogenetic (p = .006, f² = 0.01) and psychosocial (p < .001, f² = 0.02) causal beliefs. A positive interaction between psychosocial beliefs and the contact group "relatives" (p = .039) further suggests that this contact group does not benefit so strongly from psychosocial causal beliefs regarding personal stigma. Higher perceived stigma was associated with psychosocial (p < .001, f² = 0.01) and lifestyle (p < .011, f² = 0.01) causal beliefs. Regarding contact levels, the "unaffected" had significantly higher personal stigma scores than each of the other contact groups (p < .001). The contact group "affected (diagnosed)" had significantly higher perceived stigma scores than "unaffected". CONCLUSIONS: The available data show that anti-stigma campaigns should clearly communicate, that depression is not caused by an unfavorable lifestyle. In general, psychosocial or biological explanatory models should be explained. Especially for the target group "relatives of depressive patients", who can be an important support for patients, education about biogenetic explanatory models should be provided. However, it is important to note that causal beliefs are only one of many factors that impact on stigma.

Childhood sexual abuse is associated with higher total ghrelin serum levels in adulthood: results from a large, population-based study.

Ghrelin is an orexigenic peptide hormone synthesized in times of stress and hunger and alterations of the ghrelin system following acute stressors could be repeatedly shown in humans. However, little data exists on long-term effects of trauma on the ghrelin system. We aimed to investigate the influence of childhood trauma on total ghrelin serum levels in a large, population-based study. Total serum ghrelin was measured in 1666 participants of a population-based cross-sectional study ('LIFE study'). The Childhood Trauma Screener (CTS) was used for the assessment of childhood trauma in the final sample (n = 1086; mean age: 57.10 ± 16.23 years; 632 males, 454 females). Multiple linear regression analyses and generalized linear models were chosen to examine the association between childhood trauma and total serum ghrelin concentrations. Childhood sexual abuse went along with significantly higher ghrelin serum levels in the total sample (ß = 0.114, t = 3.958; p = 0.00008) and in women (ß = 0.142, t = 3.115; p = 0.002), but not in men (ß = 0.055; t = 1.388; p = 0.166). Women with severe emotional neglect in the childhood had higher ghrelin levels than those without (odds ratio = 1.204; p = 0.018). For the CTS Sum Score and other CTS sub-scale scores, no significant association with ghrelin serum levels was found. Our study is the first to show associations between childhood sexual trauma and total ghrelin levels in adults in a large, community-based sample. Our results should initiate further research of the role of ghrelin in human stress response in prospective study designs.

Public attitudes towards protecting the human rights of people with mental illness: a scoping review and data from a population trend study in Germany.

The human rights of people with mental illness are constantly threatened. We conduct a scoping review showing how public attitudes towards protecting human rights have so far been examined and providing an overview of our present knowledge of these attitudes, and present novel findings from a trend study in Germany over nine years, reporting attitudes elicited in 2020 and examining whether these attitudes have changed since 2011. Few studies address attitudes towards human rights explicitly, but several studies contain single items on either first generation human rights, mainly concerning involuntary admission, or civil liberties like the right to vote, or second generation human rights, mainly with regard to funding for healthcare, but also for example regarding career choice. Recent data from Germany showed little improvement in attitudes towards protecting human rights over the last decade and particularly high support for restricting job opportunities for people with mental illness. Although generally, most restrictions were supported by a minority of respondents only, both our data and our scoping review indicate substantial support for several restrictions in several countries, showing that public attitudes pose a challenge to the human rights of persons with mental illness. We discuss possible lines of future research.

Alterations in rhythmic and non-rhythmic resting-state EEG activity and their link to cognition in older age.

While many structural and biochemical changes in the brain have previously been associated with older age, findings concerning functional properties of neuronal networks, as reflected in their electrophysiological signatures, remain rather controversial. These discrepancies might arise due to several reasons, including diverse factors determining general spectral slowing in the alpha frequency range as well as amplitude mixing between the rhythmic and non-rhythmic parameters. We used a large dataset (N = 1703, mean age 70) to comprehensively investigate age-related alterations in multiple EEG biomarkers taking into account rhythmic and non-rhythmic activity and their individual contributions to cognitive performance. While we found strong evidence for an individual alpha peak frequency (IAF) decline in older age, we did not observe a significant relationship between theta power and age while controlling for IAF. Not only did IAF decline with age, but it was also positively associated with interference resolution in a working memory task primarily in the right and left temporal lobes suggesting its functional role in information sampling. Critically, we did not detect a significant relationship between alpha power and age when controlling for the 1/f spectral slope, while the latter one showed age-related alterations. These findings thus suggest that the entanglement of IAF slowing and power in the theta frequency range, as well as 1/f slope and alpha power measures, might explain inconsistencies reported previously in the literature. Finally, despite the absence of age-related alterations, alpha power was negatively associated with the speed of processing in the right frontal lobe while 1/f slope showed no consistent relationship to cognitive performance. Our results thus demonstrate that multiple electrophysiological features, as well as their interplay, should be considered for the comprehensive assessment of association between age, neuronal activity, and cognitive performance.

Physical activity and mental health: the connection between step count and depression, anxiety and quality of sleep.

While there are studies connecting everyday physical activity (PA) to mental health, they mostly use self-report measures for PA which are biased in multiple ways. Nevertheless, a realistic assessment of everyday PA is important for the development and implementation of low-threshold public health interventions. Therefore, we want to analyze the relationship between objectively measured daily steps and mental health. We included 1451 subjects from a subsample of the population-based LIFE-Adult-Study (2011-2014) with an average age of 55.0 years, 52.1% were female. We analyzed the effects of PA (step count measured via SenseWear Pro 3) on depression (CES-D), anxiety (GAD-7), and quality of sleep (PSQI). The regression analysis showed a significant negative association between low to moderate PA [Incidence rate ratio: 0.87 (0.77; 0.98)] as well as high to very high PA [0.84 (0.74; 0.95)] and depression and no significant associations between PA and anxiety [l-m: 0.98 (0.81; 1.18)/h-vh: 1.00 (0.82; 1.21)] or quality of sleep [l-m: 0.94 (0.84, 1.06)/h-vh: 0.92 (0.82, 1.03)], controlling for sociodemographic variables and personality. Low-threshold interventions that increase daily step count could be a useful approach for the prevention of depression. The use of objective PA measurement for research is highly encouraged.

[How Outpatient Psychotherapists Deal with Patients' Traumatic Experiences in Consideration of an Additional Qualification in Trauma Therapy]. / Umgang ambulanter Psychotherapeut*innen mit traumatischen Erfahrungen von Patient*innen unter Berücksichtigung einer traumatherapeutischen Zusatzqualifikation.

OBJECTIVE: Investigation of the differences in dealing with traumatic experiences of patients between psychotherapists with and without further training in trauma therapy or partial qualification. METHODS: Online survey of outpatient psychotherapists (N = 148) on possible obstacles in addressing traumatic experiences of patients and self-reported professional practice. RESULTS: Further training in trauma therapy is associated with a higher level of competence in professional practice and fewer obstacles in addressing traumatic experiences. CONCLUSION: A lower level of competence among psychotherapists without further training in trauma therapy speaks for the need for compulsory trainings. The expansion of low-threshold treatment offers for those affected by traumatic experiences and the dismantling of access barriers is urgently needed.

Changes in mental illness stigma over 30 years - Improvement, persistence, or deterioration?

BACKGROUND: Large efforts have been made to erase the stigma of mental illness, but it is unclear whether they have succeeded on a population level. We examine how attitudes toward people with depression or schizophrenia have evolved in Germany since 1990, and whether there are different developments for both disorders. METHODS: Using data from the three decades, four wave repeated cross-sectional representative population study in the "old" (western) states in Germany with surveys in 1990 (n = 2,044), 2001 (n = 4,005), 2011 (n = 1,984), and 2020 (n = 2,449), we calculate time-trends for social distance and emotional reactions toward someone with major depression or acute schizophrenia. RESULTS: Social distance worsened in six out of seven situations for schizophrenia, whereas improving in two out of seven situations for depression. Emotions related to fear and uneasiness increased for schizophrenia, whereas tending to decrease for depression. Pro-social reactions like the desire to help increased for depression, but decreased for schizophrenia. Initially observed differences, favoring depression over schizophrenia, widened over the 30-year study period. For schizophrenia, the biggest negative changes occurred between 1990 and 2001, whereas some improvements with regard to depression occurred more recently. CONCLUSION: Contrary to expectations, stigma has become more severe regarding acute schizophrenia in Germany over the last 30 years, whereas only slightly improving for depression. The apparent normalization of mental health problems seems not to directly translate into improving attitudes toward people with severe mental illness. Re-focusing of anti-stigma efforts on people with severe mental illness seems necessary.

Attenuation of the Heartbeat-Evoked Potential in Patients With Atrial Fibrillation.

BACKGROUND: The heartbeat-evoked potential (HEP) is a brain response to each heartbeat, which is thought to reflect cardiac signaling to central autonomic areas and suggested to be a marker of internal body awareness (eg, interoception). OBJECTIVES: Because cardiac communication with central autonomic circuits has been shown to be impaired in patients with atrial fibrillation (AF), we hypothesized that HEPs are attenuated in these patients. METHODS: By simultaneous electroencephalography and electrocardiography recordings, HEP was investigated in 56 individuals with persistent AF and 56 control subjects matched for age, sex, and body mass index. RESULTS: HEP in control subjects was characterized by right frontotemporal negativity peaking around 300 to 550 ms after the R-peak, consistent with previous studies. In comparison with control subjects, HEP amplitudes were attenuated, and HEP amplitude differences remained significant when matching the samples for heart frequency, stroke volume (assessed by echocardiography), systolic blood pressure, and the amplitude of the T-wave. Effect sizes for the group differences were medium to large (Cohen's d between 0.6 and 0.9). EEG source analysis on HEP amplitude differences pointed to a neural representation within the right insular cortex, an area known as a hub for central autonomic control. CONCLUSIONS: The heartbeat-evoked potential is reduced in AF, particularly in the right insula. We speculate that the attenuated HEP in AF may be a marker of impaired heart-brain interactions. Attenuated interoception might furthermore underlie the frequent occurrence of silent AF.

The effect of alcohol use disorder symptom and recovery narratives on problem-recognition: A randomized online trial.

BACKGROUND: Low problem recognition is a barrier to seeking treatment for alcohol use disorder ("AUD"). Promoting continuum belief narratives, which conceptualize AUD as a spectrum, together with narratives that promote non-abstinence recovery may boost self-recognition of risky drinking. This experimental study examines the effect of dichotomous vs continuous symptom narratives and non-abstinence vs abstinence recovery narratives on self-recognition of risky drinking among students. METHODS: N = 489 participants were randomized to one of four interventions combining a continuous vs dichotomous AUD symptom narrative with an abstinence vs moderated drinking AUD recovery narrative in a 2×2 design. Participants completed demographic and alcohol use (AUDIT-C) preintervention measures and postintervention measures assessing self-recognition of risky drinking and endorsement of continuum beliefs. RESULTS: Moderate drinking recovery narratives resulted in higher endorsement of continuum beliefs (F (1, 485) = 16.27, p <.001, η2p =.032 90 % CI [0.01, 0.06]). Recognizing own risky drinking behavior was unaffected by the interventions. However, in a subgroup of participants without prior AUD experience who met AUDIT-C criteria for risky drinking, the combination of a continuous symptom narrative and moderated drinking recovery narrative resulted in higher problem recognition (F (1, 48) = 5.79, p =.020, η2p =.10, 90 % CI [0.01, 0.25]). CONCLUSIONS: Exposure to moderated drinking recovery narratives may help develop an awareness in young adults that problematic alcohol use exists on a spectrum. Among those at increased risk for AUD, exposure to narratives that promote a continuous model of AUD and non-abstinence recovery may increase problem recognition.

Non-Right Handedness is Associated with More Time Awake After Sleep Onset and Higher Daytime Sleepiness Than Right Handedness: Objective (Actigraphic) and Subjective Data from a Large Community Sample.

Purpose: Handedness has been linked to various physiological and pathological phenomena including memory function and psychiatric disorders. Also for sleep, several studies have reported associations. However, large-scale studies including a broad age span of participants and studies analyzing women and men separately are lacking. Methods: Therefore, objective sleep data were determined using at-home actigraphy from 1764 healthy participants (18 to 80 years, 908 women), averaging five consecutive nights. In addition, subjective sleep-related data were captured by self-report diaries, the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS) and the Morningness-Eveningness-Questionnaire (MEQ). Handedness was determined with the Edinburgh Handedness Inventory (EHI) providing information on the direction (left vs right) and the degree of handedness (strong vs weak). To address the potential endocrine effects, premenopausal women (≤45 years) and postmenopausal women (≥55 years) were analyzed separately. This was also done for men. Results: The degree and direction of handedness were correlated with "wake after sleep onset" (WASO) in the total sample and all women (the more right-handed/lateralized the shorter WASO). In postmenopausal women, additionally, time in bed (TIB) and total sleep time (TST) were correlated. There were no other significant associations between an objective sleep variable and handedness. In both premenopausal women and >55-year-old men subjective quality of sleep (PSQI) was correlated with direction and degree of handedness (the more right-handed/lateralized the better). In the total sample and postmenopausal women, the degree and direction of handedness were negatively correlated with daytime sleepiness. The chronotype was not associated with handedness in any group. Conclusion: While associations were not consistent in all groups, overall, right-handedness tended to be associated with better sleep and less daytime sleepiness. Handedness and sleep seemed to be differentially associated in women and men, being in line with endocrine interactions.

Trauma assessment in outpatient psychotherapy and associations with psychotherapist's gender, own traumatic events, length of work experience, and theoretical orientation.

BACKGROUND: Traumatic events are strongly associated with mental health problems. At present, traumatic events and trauma-specific needs are commonly underdetected in therapeutic settings. Many mental health professionals lack key competencies for trauma inquiry and treatment. OBJECTIVE: In this study, we aimed to investigate the everyday practices of dealing with traumatic events in outpatient psychotherapy in Germany as well as the influence of the therapist's gender, own traumatic events, length of professional experience, and theoretical orientation. METHOD: A total of 148 outpatient psychotherapists completed a purpose-designed online questionnaire. Therapists rated barriers and attitudes towards trauma assessment, possible requirements for enquiring about trauma, and practical aspects of trauma assessment. RESULTS: Barriers reported in previous studies, e.g. fear of offending the patient or exacerbating their psychological state, could not be confirmed in our sample. Overall, participating therapists felt confident in engaging with traumatic events and considered enquiring about trauma important in all patients. Group differences were found for therapist's gender, own traumatic events, length of work experience, and theoretical orientation. CONCLUSIONS: Our results suggest that trauma training lowers barriers and raises therapists' self-confidence in dealing with patients´ traumatic experiences. Therapists' characteristics effecting trauma assessment should be considered during training. Due to the increasing demand for psychotherapy, especially considering people with severe mental illness affected by traumatic events, trauma training should be obligatory for all mental health professionals.

Antecedentes: Los eventos traumáticos están fuertemente asociados a problemas de salud mental. En la actualidad, los eventos traumáticos y las necesidades específicas asociadas al trauma no suelen ser detectadas en entornos terapéuticos. Muchos profesionales de salud mental carecen de las competencias para indagar sobre el trauma y tratarlo.Objetivo: En este estudio, el objetivo fue el investigar las prácticas cotidianas del abordaje de los eventos traumáticos en la psicoterapia ambulatoria de Alemania, así como investigar la influencia que el género del terapeuta, sus propios eventos traumáticos, el tiempo de su experiencia laboral y su orientación teórica tiene sobre esto.Métodos: Ciento cuarenta y ocho (148) psicoterapeutas de atención ambulatoria completaron un cuestionario en línea diseñado para el propósito del estudio. Los psicoterapeutas calificaron las barreras y actitudes respecto a la evaluación del trauma, los posibles requisitos para preguntar sobre el trauma y los aspectos prácticos de la evaluación del trauma.Resultados: No se pudieron confirmar las barreras reportadas en estudios previos como, por ejemplo, el temor a ofender al paciente o el empeorar su estado psicológico. En general, los psicoterapeutas participantes sentían confianza al momento de abordar los eventos traumáticos y consideraron que el preguntar sobre el trauma era importante en todos los pacientes. Se encontraron diferencias según el género del psicoterapeuta, sus propios eventos traumáticos, el tiempo de su experiencia laboral y su orientación teórica.Conclusiones: Nuestros resultados sugieren que el entrenamiento en trauma disminuye las barreras e incrementa la confianza de los psicoterapeutas consigo mismos para abordar las experiencias traumáticas de los pacientes. Las características de los psicoterapeutas que afectan la evaluación del trauma deben ser consideradas durante el entrenamiento. Debido a que existe un incremento en la demanda de psicoterapia, considerando especialmente a las personas con enfermedad mental severa afectadas por eventos traumáticos, el entrenamiento en trauma debería ser obligatorio para todos los profesionales de salud mental.

Relationship between regional white matter hyperintensities and alpha oscillations in older adults.

Aging is associated with increased white matter hyperintensities (WMHs) and with alterations of alpha oscillations (7-13 Hz). However, a crucial question remains, whether changes in alpha oscillations relate to aging per se or whether this relationship is mediated by age-related neuropathology like WMHs. Using a large cohort of cognitively healthy older adults (N = 907, 60-80 years), we assessed relative alpha power, alpha peak frequency, and long-range temporal correlations from resting-state EEG. We further associated these parameters with voxel-wise WMHs from 3T MRI. We found that a higher prevalence of WMHs in the superior and posterior corona radiata as well as in the thalamic radiation was related to elevated alpha power, with the strongest association in the bilateral occipital cortex. In contrast, we observed no significant relation of the WMHs probability with alpha peak frequency and long-range temporal correlations. Finally, higher age was associated with elevated alpha power via total WMH volume. We suggest that an elevated alpha power is a consequence of WMHs affecting a spatial organization of alpha sources.

Loss and grief in elderly people: Results from the LIFE-Adult-Study.

We evaluated 2,865 elderly people to investigate the prevalence of prolonged grief disorder (PGD), examine predictors and mental health correlates. The conditional prevalence of PGD varied between 0.8% and 5.2% (diagnostic algorithm vs. cut-off). PG-13 scores were related to depressive symptoms, sleep disturbances, reduced life satisfaction, and quality of life. Predictors were female gender, less time since death, more losses, having lost a child, partner, or sibling, and less social support. PGD is associated with adverse mental health consequences. Practitioners should pay special attention to elderly women who lost a close loved one and lack social support.

Is unemployment associated with inefficient sleep habits? A cohort study using objective sleep measurements.

Unemployed people could be at risk of developing inefficient sleep habits by spending excessive time in bed, as they lack a structuring activity. This could impact their mental health and reintegration into labour. This study aims to analyse possible associations between employment status and sleep parameters using actigraphy. Subjects (148 employed and 50 unemployed) were drawn from a German population-based cohort. Sleep parameters were measured with the SenseWear Bodymedia Pro 3 armband. Comparison of means concerning sleep duration, sleep efficiency, time of sleep and sleep fragmentation was performed separately for week days and weekends. Multiple linear regression analysis was performed to analyse group differences controlling for covariates. Finally, we defined cut-off scores for each sleep variable, and analysed the distribution of subjects above and below these values. Unemployed people did not sleep significantly longer than employed people. However, on week days, they displayed night sleep efficiency reduced by on average > 5% points, they lay down for 28 min longer, had later mid sleep time (38 min) and sleep offset (55 min), as well as more frequent awakenings after sleep onset accounting for being awake 28 min longer (all p ≤ 0.005). Sleep in unemployed subjects compared with employed subjects aged 41-64 years was less efficient, more fragmented and shifted to a later point of the night. Results support prior findings that unemployment has a negative influence on sleep quality. Unemployed individuals could benefit from intervention programmes aiming at the adoption of healthier sleep habits.

[Psychometric Evaluation of a Long and Short German Version of the Prejudice Towards People with Mental Illness Scale (PPMI-D)]. / Psychometrische Evaluation einer deutschen Version der Lang- und Kurzform der Prejudice towards People with Mental Illness Scale (PPMI-D).

OBJECTIVE: We present a German version of the Prejudice towards People with Mental Illness Scale in long (PPMI-DL) and short form (PPMI-DK) and provide a psychometric evaluation in a German population sample. METHODS: After German translation (including back-translation), an online survey (N = 1004) was conducted. RESULTS: Item difficulty and selectivity are in the desirable medium range. Internal consistencies are high to excellent (PPMI-DL: α = 0.919; PPMI-DK: α = 0.872) in the overall scale. Confirmatory factor analyses confirm the 4 subscales of the original scale. Medium correlations are found with authoritarian attitudes (KSA-3) and low negative correlations with social desirability (KSE-G). Norm values for the PPMI subscales are reported. CONCLUSION: The PPMI-D can be used in German-speaking countries to survey prejudice towards people with mental illness.
