“Blood for Blood”? Personal Motives and Deterrents for Blood Donation in the German Population
(2021)
Abstract
Background
Comorbidities in mental disorders are often understood by assuming a common cause. The network theory of mental disorders offers an alternative to this assumption by understanding comorbidities as mutually reinforced problems. In this study, we used network analysis to examine bridge symptoms between anxiety and depression in a large sample.
Method
Using data from a sample of patients diagnosed with both depression and an anxiety disorder before and after inpatient treatment (N = 5,614, mean age: 42.24, 63.59% female, average treatment duration: 48.12 days), network models of depression and anxiety symptoms are estimated. Topology, the centrality of nodes, stability, and changes in network structure are analyzed. Symptoms that drive comorbidity are determined by bridge node analysis. As an alternative to network communities based on categorical diagnosis, we performed a community analysis and propose empirically derived symptom subsets.
Results
The obtained network models are highly stable. Sad mood and the inability to control worry are the most central. Psychomotor agitation or retardation is the strongest bridge node between anxiety and depression, followed by concentration problems and restlessness. Changes in appetite and suicidality were unique to depression. Community analysis revealed four symptom groups.
Conclusion
The estimated network structure of depression and anxiety symptoms proves to be highly accurate. Results indicate that some symptoms are considerably more influential than others and that only a small number of predominantly physical symptoms are strong candidates for explaining comorbidity. Future studies should include physiological measures in network models to provide a more accurate understanding.
Körpersignale sind elementar für die Aufrechterhaltung der Homöostase, um eine angemessene Regulation der Körperfunktionen zu ermöglichen und dadurch das Überleben des Individuums sicherzustellen. Die bisherige Forschung hat die dysfunktionale Wahrnehmung dieser interozeptiven Signale als wichtigen Bestandteil vieler Angst- und Gesundheitsprobleme identifiziert, da selbst leichte und harmlose Körperempfindungen eine übermäßig starke Mobilisierung von Abwehrreaktionen hervorrufen können. Obwohl das wissenschaftliche Interesse im Bereich Interozeption in den letzten Jahren stark gewachsen ist, wurde die Dynamik von Abwehrreaktionen als Reaktion auf Körpersignale bisher selten untersucht. Daher hatte die vorliegende Arbeit zum Ziel, die verhaltensbezogene und psychophysiologische Dynamik der defensiven Mobilisierung auf bedrohliche interozeptive Signale sowie den moderierenden Effekt von Dispositionsfaktoren und biologisch determinierten Verhaltensmarkern zu untersuchen.
In der ersten Studie wurden die Dynamik defensiver Mobilisierung auf eine näher-kommende externe Bedrohung mit einer sich annähernden interozeptiven respiratorischen Bedrohung, in Abhängigkeit von der Bedrohungsnähe und der Möglichkeit zur Vermeidung, bezüglich subjektiver, autonomer und respiratorische Reaktionen sowie Gehirnreaktionen und defensiver Reflexe verglichen.
In der zweiten Studie wurde die Mobilisierung defensiver Reaktionen während der wiederholten Vermeidung von kulminierender Atemnot analysiert, um eine detaillierte Analyse der Initiierung und Aufrechterhaltung von aktiven Vermeidungsverhalten zu erhalten.
Die dritte Studie unterweiterte die diese Befunde, indem die Rolle der maximalen freiwilligen Luftanhaltezeit als möglicher Prädiktor für eine übermäßig starke Mobilisierung defensiver Reaktionen bei der Konfrontation mit einer näherkommenden respiratorischen Bedrohung, in Abhängigkeit der Möglichkeit zur Vermeidung, untersucht wurde.
In der vierten Studie wurden die Prädiktoren für aktives Abwehrverhalten (d.h., Flucht oder aktive Vermeidung bei Konfrontation) während ansteigender Atemnot, induziert durch in der Intensität ansteigende inspiratorische Atemwiderstände gefolgt von einer kurzen Blockade der Einatmung, untersucht.
Die erste Studie zeigte, dass das defensive Aktivierungsmuster bei der Mobilisierung defensiver Reaktionen auf eine sich annähernde externe Bedrohung annähernd vergleichbar ist wie bei einer interozeptiven respiratorischen Bedrohung, unabhängig von der Möglichkeit zur Vermeidung. Zusätzlich wurde eine bedrohungsspezifische Mobilisierung des respiratorischen Systems bei der Konfrontation mit der unvermeidbaren interozeptiven Bedrohung beobachtet.
Die Daten der zweiten Studie demonstrierten, dass die Initiierung von erstmaligen Vermeidungsverhalten als Reaktion auf ansteigende Atemnot begleitet wird von physiologischen Erregungen als Indikatoren für eine Reaktionsvorbereitung. Diese verschwanden zunehmend mit wiederholter Vermeidung, was auf die Entwicklung von gewohnheitsmäßiger Vermeidung hindeutet.
Darüber hinaus wurde in der dritten Studie gezeigt, dass eine übermäßig starke Mobilisierung von Abwehrreaktionen auf eine sich annähernde unvermeidbare respiratorische Bedrohung durch eine reduzierte maximale freiwillige Luftanhaltezeit vorhergesagt wird, jedoch nicht, wenn die Möglichkeit zur Vermeidung vorhanden war.
Die vierte Studie demonstrierte, dass eine höhere Angstempfindlichkeit und eine kürzere freiwillige maximale Luftanhaltezeit mit aktivem Vermeidungsverhalten während ansteigender Atemnot assoziiert sind.
Zusammenfassend zeigen die vorliegenden Daten, dass die defensive Mobilisierung für eine exterozeptive Bedrohung vergleichbar ist wie für eine interozeptive Bedrohung und sich in Abhängigkeit der Bedrohungsnähe und dem verfügbarem Abwehrrepertoire ändert. Darüber hinaus ist die Neigung, Erregungsgefühle zu befürchten und eine verminderte Belastungstoleranz während freiwilligem Luftanhaltens mit einer erhöhten Angst- und Furchtreaktion auf Atemnotsymptome verbunden. Daher könnten diese dispositionellen und biologischen Verhaltensmarker bei der Konfrontation mit ansteigender Atemnot aktives Vermeidungsverhalten begünstigen und, wenn sie gewohnheitsmäßig ausgeführt werden, kann sich persistentes Vermeidungsverhalten entwickeln, welches das Risiko für die Entstehung einer ernsthaften psychischen Erkrankung erhöht.
Quality of life (QoL) is a core patient-reported outcome in healthcare research, alongside primary clinical outcomes. A conceptual, operational, and psychometric elaboration of QoL in the context of TM is needed, because standardized instruments to assess QoL do not sufficiently represent essential aspects of intended outcomes of telemedical applications (TM). The overall aim is to develop an instrument that can adequately capture QoL in TM. For that purpose, an extended working model of QoL will be derived. Subsequently, an instrument will be developed and validated that captures those aspects of QoL that are influenced by TM. The initial exploratory study section includes (a) a systematic literature review, (b) a qualitative survey for concept elicitation, and (c) pre-testings using cognitive debriefings with patients and an expert workshop. The second quantitative section consists of an online expert survey and two patient surveys for piloting and validation of the newly developed instrument. The resulting questionnaire will assess central experiences of patients regarding telemedical applications and its impact on QoL more sensitively. Its use as adjunct instrument will lead to a more appropriate evaluation of TM and contribute to the improvement of care tailored to patients’ individual needs.
Quality of Life in Young Adults With Cerebral Palsy: A Longitudinal Analysis of the SPARCLE Study
(2021)
Introduction: While most people with cerebral palsy (CP) will have a life expectancy similar to that of the general population, international research has primarily focused on childhood and adolescence; and knowledge about the quality of life (QoL) of young adults with CP, its trajectories, and associated factors remains scarce.
Methods: This longitudinal study included young adults with CP living in five European regions and who had previously participated in the SPARCLE cohort as children and/or adolescents. Their QoL in the psychological well-being and social relationships domains was estimated using age-appropriate validated instruments (KIDSCREEN-52 in childhood/adolescence and WHOQOL-Bref in young adulthood). We used generalized linear mixed-effect models with random intercept to estimate long-term trajectories of QoL in both domains and to investigate whether severity of impairment, pain, and seizure influenced these trajectories. We sought to identify potentially different trajectories of QoL from childhood to adulthood using a shape-based clustering method.
Results: In total, 164 young adults with CP aged 22–27 years participated in the study. Psychological well-being linearly decreased by 0.78 points (scale 0–100) per year (95% confidence interval (CI) −0.99 to −0.56) from childhood to young adulthood, whereas QoL in the social relationships domain increased (β coefficient 1.24, 95% CI 0.92–1.55). Severity of impairment was associated with reduced QoL in all life periods of the study (childhood, adolescence, and young adulthood): motor impairment with social relationships, and more nuancedly intellectual disability with psychological well-being and social relationships. At all periods, frequent pain significantly reduced psychological well-being, and seizures were associated with lower QoL in the social relationships domain. In both domains, we identified a group of individuals with CP who presented a reverse trajectory compared with the general QoL trajectory.
Conclusion: Identification of QoL trajectories and their associated factors yields improved knowledge about the experience of individuals with CP until young adulthood. Further studies are needed to better understand the determinants that have the greatest influence on the different shapes of long-term trajectories of QoL.
Moral rules are a cornerstone of many societies. Most moral rules are concerned with the welfare of other individuals, reflecting individuals’ innate aversion against harming other individuals. Harming others is associated with aversive experiences, implying that individuals who are sensitive to the aversiveness of these experiences are more likely to follow moral rules than individuals who are insensitive to the aversiveness of these experiences. Individuals’ sensitivity for aversive experiences depends on individuals’ ability to integrate the underlying neural and physiological processes: Individuals who are more efficient in integrating these processes are more sensitive to the aversiveness that is associated with moral rule violations than individuals who are less efficient in integrating these processes. Individuals who differ in their ability to integrate these processes may, thus, also differ in their inclination to follow moral rules. We tested this assumption in a sample of healthy individuals (67 males) who completed measures of moral rule adherence and integration abilities. Moral rule adherence was assessed with self-report measure and integration abilities were assessed with a resting state measure of heart rate variability (HRV), which reflects prefrontal–(para-)limbic engagement during the integration of physical and neural processes. We found a positive association between individuals’ HRV and individuals’ moral rule adherence, implying that individuals with efficient integration abilities were more inclined to follow moral rules than individuals with inefficient integration abilities. Our findings support the assumption that individuals with different integration abilities also differ in moral rule adherence, presumably because of differences in aversiveness sensitivity.
Background: Depression is a highly prevalent mental disorder, but only a fraction of those affected receive evidence-based treatments. Recently, Internet-based interventions were introduced as an efficacious and cost-effective approach. However, even though depression is a heterogenous construct, effects of treatments have mostly been determined using aggregated symptom scores. This carries the risk of concealing important effects and working mechanisms of those treatments.
Methods: In this study, we analyze outcome and long-term follow-up data from the EVIDENT study, a large (N = 1,013) randomized-controlled trial comparing an Internet intervention for depression (Deprexis) with care as usual. We use Network Intervention Analysis to examine the symptom-specific effects of the intervention. Using data from intermediary and long-term assessments that have been conducted over 36 months, we intend to reveal how the treatment effects unfold sequentially and are maintained.
Results: Item-level analysis showed that scale-level effects can be explained by small item-level effects on most depressive symptoms at all points of assessment. Higher scores on these items at baseline predicted overall symptom reduction throughout the whole assessment period. Network intervention analysis offered insights into potential working mechanisms: while deprexis directly affected certain symptoms of depression (e.g., worthlessness and fatigue) and certain aspects of the quality of life (e.g., overall impairment through emotional problems), other domains were affected indirectly (e.g., depressed mood and concentration as well as activity level). The configuration of direct and indirect effects replicates previous findings from another study examining the same intervention.
Conclusions: Internet interventions for depression are not only effective in the short term, but also exert long-term effects. Their effects are likely to affect only a small subset of problems. Patients reporting these problems are likely to benefit more from the intervention. Future studies on online interventions should examine symptom-specific effects as they potentially reveal the potential of treatment tailoring.
Clinical Trial Registration: ClinicalTrials.gov, Identifier: NCT02178631.
Ungeachtet der Alltagsrelevanz ist die empirische Evidenz zur Regulation selbstbewer-tender Emotionen im Forschungsfeld unterrepräsentiert. In Dual-Process-Ansätzen wurden Zusammenhänge zwischen Emotionen, kognitiver Emotionsregulation und Entscheidungs-verhalten in moralischen Konflikten modelliert. Jüngere Befunde legen nahe, dass habituelles und experimentell induziertes Reappraisal – mediiert über die emotionale Erregung – positiv mit konsequentialistischen Urteilen und Entscheidungen assoziiert sind.
Ziel der Arbeit ist es, den Einfluss kognitiver Emotionsregulation auf das Entscheidungs-verhalten in moralischen Alltagsdilemmata zu untersuchen. Welche kognitiven Strategien kommen bei der Schuld- und Schamregulation zum Einsatz? Welche Wirkung entfalten sie auf verschiedene Outcomes (emotionales Erleben, Entscheidungsverhalten)? Inwiefern unterscheiden sich Formen und Taktiken des Reappraisal in ihrer Wirkung?
In einem ersten Schritt wurden schuld- und schamauslösende Dilemmata entwickelt und anhand definierter Kriterien selektiert. Eine Studienreihe betrachtete den Einfluss habitueller, kognitiver Emotionsregulation und experimentell manipuliertem Reappraisal auf das Entscheidungsverhalten in diesen Dilemmata. Tendenziell begünstigten funktionale Strategien aus der Reappraisal-Familie konsequentialistische Entscheidungen. Der Media-tionseffekt über die emotionale Erregung konnte nicht repliziert werden. Eine zweite Studien-reihe mit explorativer Methodik beabsichtigte, die Phänomenologie von Reappraisal-Taktiken bei einem moralischen Entscheidungskonflikt abzubilden. Mittels eines Kategoriensystems konnten problemorientierte und externalisierende Reappraisal-Taktiken identifiziert werden.
Limitationen der Untersuchungen und Anknüpfungspunkte für zukünftige Forschung werden ebenso diskutiert wie Implikationen der Ergebnisse für die klinische und forensische Praxis.
Over the last decades, various predictors have proven relevant for job performance [e.g., general mental ability (GMA), broad personality traits, such as the Big Five]. However, prediction of job performance is far from perfect, and further potentially relevant predictors need to be investigated. Narrower personality traits, such as individuals' character strengths, have emerged as meaningfully related to different aspects of job performance. However, it is still unclear whether character strengths can explain additional variance in job performance over and above already known powerful predictors. Consequently, the present study aimed at (1) examining the incremental validity of character strengths as predictors of job performance beyond GMA and/or the Big Five traits and (2) identifying the most important predictors of job performance out of the 24 character strengths, GMA, and the Big Five. Job performance was operationalized with multidimensional measures of both productive and counterproductive work behavior. A sample of 169 employees from different occupations completed web-based self-assessments on character strengths, GMA, and the Big Five. Additionally, the employees' supervisors provided web-based ratings of their job performance. Results showed that character strengths incrementally predicted job performance beyond GMA, the Big Five, or GMA plus the Big Five; explained variance increased up to 54.8, 43.1, and 38.4%, respectively, depending on the dimension of job performance. Exploratory relative weight analyses revealed that for each of the dimensions of job performance, at least one character strength explained a numerically higher amount of variance than GMA and the Big Five, except for individual task proactivity, where GMA exhibited the numerically highest amount of explained variance. The present study shows that character strengths are relevant predictors of job performance in addition to GMA and other conceptualizations of personality (i.e., the Big Five). This also highlights the role of socio-emotional skills, such as character strengths, for the understanding of performance outcomes above and beyond cognitive ability.
Introduction: To maintain a sufficient donor pool, deferred first-time donors (FTD) should be motivated to return for blood donation. This pilot study investigates how deferral affects momentary mood, satisfaction with the donation process, and subsequent return behavior to examine their potential for motivating (deferred) FTD. Methods: All of the subjects (n = 96) completed a first questionnaire (A1) before pre-donation assessment. Deferred FTD (n = 22) were asked to complete a second questionnaire (A2) immediately after deferral, while non-deferred FTD (n = 74) filled in the second questionnaire (A3) after blood donation. The impact of deferral, momentary mood, and satisfaction with the donation process on return behavior within 12 months was tested by calculating two path analyses, controlling for sex and age. Results: Mood (p < 0.001) and satisfaction with social aspects of the donation process (p = 0.01) were decreased after deferral. Deferred FTD were less likely than non-deferred FTD to return to the blood donation center within 12 months (60.8 vs. 36.4%; p = 0.043). However, path analyses revealed that deferral effects on mood and satisfaction were not connected to return behavior. Instead, age had a significant influence on return behavior (p < 0.05) such that, overall, non-returning FTD were older than returning FTD, regardless of their deferral status. Conclusion: Our findings suggest that mood and satisfaction with the donation process are directly affected by deferral but not clearly responsible for low return rates. It seems promising to embed these variables in established health behavior models in further studies to increase the return rates of deferred FTD.
Our emotional experiences depend on our interoceptive ability to perceive and interpret changes in our autonomous nervous system. An inaccurate perception and interpretation of autonomic changes impairs our ability to understand and regulate our emotional reactions. Impairments in emotion understanding and emotion regulation increase our risk for mental disorders, indicating that interoceptive deficits play an important role in the etiology and pathogenesis of mental disorders. We, thus, need measures to identify those of us whose interoceptive deficits impair their emotion understanding and emotion regulation. Here, we used cardiac measures to investigate how our ability to engage prefrontal and (para-)limbic brain region regions affects our ability to perceive and interpret cardiac changes. We administered a heartbeat detection task to a sample of healthy individuals (n = 113) whose prefrontal-(para-) limbic engagement had been determined on basis of a heart rate variability recording. We found a positive association between heartbeat detection and heart rate variability, implying that individuals with higher heart rate variability were more accurate in heartbeat detection than individuals with lower heart rate variability. These findings suggest that our interoceptive accuracy depends on our prefrontal-(para-)limbic engagement during the perception and interpretation of cardiac changes. Our findings also show that cardiac measures may be useful to investigate the association between interoceptive accuracy and prefrontal-(para-)limbic engagement in a time- and cost-efficient manner.
Functional connectivity studies have demonstrated that creative thinking builds upon an interplay of multiple neural networks involving the cognitive control system. Theoretically, cognitive control has generally been discussed as the common basis underlying the positive relationship between creative thinking and intelligence. However, the literature still lacks a detailed investigation of the association patterns between cognitive control, the factors of creative thinking as measured by divergent thinking (DT) tasks, i.e., fluency and originality, and intelligence, both fluid and crystallized. In the present study, we explored these relationships at the behavioral and the neural level, based on N = 77 young adults. We focused on brain-signal complexity (BSC), parameterized by multi-scale entropy (MSE), as measured during a verbal DT and a cognitive control task. We demonstrated that MSE is a sensitive neural indicator of originality as well as inhibition. Then, we explore the relationships between MSE and factor scores indicating DT and intelligence. In a series of across-scalp analyses, we show that the overall MSE measured during a DT task, as well as MSE measured in cognitive control states, are associated with fluency and originality at specific scalp locations, but not with fluid and crystallized intelligence. The present explorative study broadens our understanding of the relationship between creative thinking, intelligence, and cognitive control from the perspective of BSC and has the potential to inspire future BSC-related theories of creative thinking.
This review assessed population-based estimate rates of cancer patients with minor and young adult children (≤ 25 years), children and young adults having a parent with cancer as well as the psychosocial situation and well-being of children and young adults affected by parental cancer. Eighteen publications on population-based studies were included. Studies varied in the age ranges of both cancer patients and children. The prevalence rates of cancer patients having children ranged from 14 to 24.7% depending on the sample structure (e.g., age, gender). Studies reported that between 1.6 and 8.4% of children resp. young adult children have a parent with a history of cancer. Seven publications reported on the psychosocial situation or well-being in children and young adults affected by parental cancer. Estimate rates of psychosocial problems, psychiatric diagnoses or distress ranged between 2.5 and 34% of children depending on the method of measurement and outcome. The differences in the sample structure between the studies impeded the comparison of prevalence rates. However, the findings help to determine the need for specific support services and health care planning. The results emphazise the importance to routinely include issues on the parental role of patients and questions on the well-being and coping of children into psychooncological care. If necessary, support should be provided to families living with a cancer diagnosis.
Abstract
Background
The need to optimize exposure treatments for anxiety disorders may be addressed by temporally intensified exposure sessions. Effects on symptom reduction and public health benefits should be examined across different anxiety disorders with comorbid conditions.
Methods
This multicenter randomized controlled trial compared two variants of prediction error‐based exposure therapy (PeEx) in various anxiety disorders (both 12 sessions + 2 booster sessions, 100 min/session): temporally intensified exposure (PeEx‐I) with exposure sessions condensed to 2 weeks (n = 358) and standard nonintensified exposure (PeEx‐S) with weekly exposure sessions (n = 368). Primary outcomes were anxiety symptoms (pre, post, and 6‐months follow‐up). Secondary outcomes were global severity (across sessions), quality of life, disability days, and comorbid depression.
Results
Both treatments resulted in substantial improvements at post (PeEx‐I: dwithin = 1.50, PeEx‐S: dwithin = 1.78) and follow‐up (PeEx‐I: dwithin = 2.34; PeEx‐S: dwithin = 2.03). Both groups showed formally equivalent symptom reduction at post and follow‐up. However, time until response during treatment was 32% shorter in PeEx‐I (median = 68 days) than PeEx‐S (108 days; TRPeEx‐I = 0.68). Interestingly, drop‐out rates were lower during intensified exposure. PeEx‐I was also superior in reducing disability days and improving quality of life at follow‐up without increasing relapse.
Conclusions
Both treatment variants focusing on the transdiagnostic exposure‐based violation of threat beliefs were effective in reducing symptom severity and disability in severe anxiety disorders. Temporally intensified exposure resulted in faster treatment response with substantial public health benefits and lower drop‐out during the exposure phase, without higher relapse. Clinicians can expect better or at least comparable outcomes when delivering exposure in a temporally intensified manner.
Background: There is an urgent need for effective follow-up treatments after acute electroconvulsive therapy (ECT) in depressed patients. Preliminary evidence suggests psychotherapeutic interventions to be a feasible and efficacious follow-up treatment. However, there is a need for research on the long-term usefulness of such psychotherapeutic offers in a naturalistic setting that is more representative of routine clinical practice. Therefore, the aim of the current pilot study was to investigate the effects of a half-open continuous group cognitive behavioral therapy (CBT) with cognitive behavioral analysis system of psychotherapy elements as a follow-up treatment for all ECT patients, regardless of response status after ECT, on reducing depressive symptoms and promoting psychosocial functioning.
Method: Group CBT was designed to support patients during the often-difficult transition from inpatient to outpatient treatment. In a non-controlled pilot trial, patients were offered 15weekly sessions of manualized group CBT (called EffECTiv 2.0). The Montgomery-Åsberg Depression Rating Scale was assessed as primary outcome; the Beck Depression Inventory, WHO Quality of Life Questionnaire–BREF, and the Cognitive Emotion Regulation Questionnaire were assessed as secondary outcomes. Measurements took place before individual group start, after individual group end, and 6months after individual group end.
Results: During group CBT, Post-ECT symptom reduction was not only maintained but there was a tendency toward a further decrease in depression severity. This reduction could be sustained 6months after end of the group, regardless of response status after ECT treatment. Aspects of quality of life and emotion regulation strategies improved during group CBT, and these improvements were maintained 6months after the end of the group.
Conclusion: Even though the interpretability of the results is limited by the small sample and the non-controlled design, they indicate that manualized group CBT with cognitive behavioral analysis system of psychotherapy elements might pose a recommendable follow-up treatment option after acute ECT for depressed patients, regardless of response status after ECT. This approach might not only help to further reduce depressive symptoms and prevent relapse, but also promote long-term psychosocial functioning by improving emotion regulation strategies and psychological quality of life and thus could be considered as a valuable addition to clinical routine after future validation.

Background: Interpersonal skills deficits and dysfunctional metacognitive beliefs have been implicated in the etiology and maintenance of depression. This study aimed to investigate the association between changes in these skills deficits and change in depressive symptoms over the course of treatment with Cognitive Behavioral Analysis System of Psychotherapy (CBASP) and Metacognitive Therapy (MCT).
Methods: In this prospective, parallel group observational study, data was collected at baseline and after 8 weeks of an intensive day clinic psychotherapy program. Based on a shared decision between patients and clinicians, patients received either CBASP or MCT. Ninety patients were included in the analyses (CBASP: age M = 38.7, 40.5% female, MCT: age M = 44.7, 43.3% female). Interpersonal deficits were assessed with the short-form of the Luebeck Questionnaire for Recording Preoperational Thinking (LQPT-SF) and the Impact Message Inventory (IMI-R). Metacognitive beliefs were assessed with the Metacognition Questionnaire-30 (MCQ-30). The Quick Inventory of Depressive Symptomatology (QIDS-SR16) was utilized to assess depressive symptoms. A regression analysis was conducted to assess variables associated with outcome. ANCOVAs were utilized to investigate whether improvement in skills deficits is dependent on type of treatment received.
Results: Improvements in preoperational thinking and increases in friendly-dominant behavior were associated with change in depressive symptoms. There was no association between reductions in dysfunctional metacognitive beliefs and a decrease in depressive symptoms. While both treatment groups showed significant improvements in interpersonal and metacognitive skills, there was no significant between-group difference in the change scores for either of these skills.
Conclusion: Our findings suggest that changes in interpersonal skills seem to be of particular relevance in the treatment of depression. These results have to be replicated in a randomized-controlled design before firm conclusions can be drawn.
Introduction: The Cognitive Behavioral Analysis System of Psychotherapy (CBASP) was developed for the treatment of persistent depressive disorder (PDD), where comorbid personality disorders (PD) are common. In contrast to other PD, comorbid borderline personality disorder (BPD) is often regarded as an exclusion criterion for CBASP. In clinical settings, however, subthreshold BPD symptoms are prevalent in PDD and may not be obvious at an initial assessment prior to therapy. As data on their impact on CBASP outcome are very limited, this naturalistic study investigates BPD features in PDD and their relevance for the therapeutic outcome of a multimodal CBASP inpatient program.
Method: Sixty patients (37 female, mean age 38.3, SD 11.9 years) meeting DSM-5 criteria for PDD underwent a 10 weeks CBASP inpatient program. BPD features (i.e., number of fulfilled DSM-5 criteria) together with childhood maltreatment and rejection sensitivity were assessed on admission. Before and after treatment, severity of depressive symptoms was measured using the Montgomery-Asberg Depression Rating Scale (MADRS) and the Beck Depression Inventory (BDI-II). BPD symptoms were assessed using the Borderline Personality Disorder Severity Index (BPDSI-IV) and the Borderline Symptom List (BSL-23). Intercorrelations of baseline characteristics and symptom change during treatment were analyzed.
Results: Patients with PDD met a mean of 1.5 (SD 1.6) BPD criteria with 4 patients fulfilling ≥5 criteria. BPD symptoms and depressive symptoms showed a strong correlation, and BPD symptoms were additionally correlated with emotional abuse and rejection sensitivity. There was no association between BPD features at baseline and improvement on the MADRS, however, BPD features tended to be associated with a lower response according to the BDI-II score after 10 weeks of treatment. Furthermore, BPD symptoms (i.e., abandonment, impulsivity and affective instability) were reduced after 10 weeks of CBASP treatment.
Discussion: BPD symptoms are prevalent in patients with PDD and highly intertwined with the experience of depressive symptoms. In this naturalistic study in PDD, BPD features at baseline did not limit the clinical response to CBASP. Future studies may extend the spectrum of PDD to comorbid subsyndromal or even syndromal BPD in order to develop tailored psychotherapeutic treatment for these complex affective disorders.
