Loss, gain and choice difficulty in gambling patients: Neural and behavioural processes.

Impaired decision-making is often displayed by individuals suffering from gambling disorder (GD). Since there are a variety of different phenomena influencing decision-making, we focused in this study on the effects of GD on neural and behavioural processes related to loss aversion and choice difficulty. Behavioural responses as well as brain images of 23 patients with GD and 20 controls were recorded while they completed a mixed gambles task, where they had to decide to either accept or reject gambles with different amounts of potential gain and loss. We found no behavioural loss aversion in either group and no group differences regarding loss and gain-related choice behaviour, but there was a weaker relation between choice difficulty and decision time in patients with GD. Similarly, we observed no group differences in processing of losses or gains, but choice difficulty was weaker associated with brain activity in the right anterior insula and anterior cingulate cortex in patients with GD. Our results showed for the first time the effects of GD on neural processes related to choice difficulty. In addition, our findings on choice difficulty give new insights on the psychopathology of GD and on neural processes related to impaired decision-making in GD.

The association between problematic smartphone use and symptoms of anxiety and depression-a meta-analysis.

BACKGROUND: Recent research links problematic smartphone use (PSU) and mental health problems. The purpose of this meta-analysis was to evaluate the relationship between PSU and symptoms of anxiety and/or depression. METHODS: We searched for research literature published recently in PubMed and Google Scholar via a systematic literature search. Twenty-seven studies published since 2014 with 120 895 participants were included in the meta-analysis. RESULTS: PSU was moderately but robustly associated with both anxiety, r = 0.29 (95% CI: 0.23-0.35), and depression, r = 0.28 (95% CI: 0.22-0.34), P < 0.001 for both. Homogeneity tests showed significant P-values for anxiety and depression, but without affecting the results. Neither the age of the participants, publication year nor the study quality could explain the heterogeneity. Furthermore, we found no evidence for publication bias, since Egger's regression test showed no significance for depression (P = 0.21) and anxiety (P = 0.35). CONCLUSIONS: Our study shows that PSU can be viewed as an indicator of symptoms of anxiety and depression and a possible manifestation of these mental health problems in modern society. Furthermore, PSU as a maladaptive coping behavior may contribute by worsening these symptoms. PSU screening should thus become part of standard clinical psychological diagnostic procedures.

Features of Self-Organization during the Process of Mindfulness-Based Stress Reduction: A Single Case Study.

Compared to the extensive evidence of the effectiveness of mindfulness-based interventions, there is only a limited understanding of their mechanisms of change. The three aims of this study are (1) to identify features of self-organization during the process (e.g., pattern transitions), (2) to obtain an impression of the effects of continuous self-assessments and feedback sessions on mindfulness-related stress reduction, and (3) to test the feasibility of high-frequency process monitoring and process feedback. Concerning aim (1), the specific hypothesis is that change will occur as a cascade of discontinuous pattern transitions emerging spontaneously in the sense of not being a reaction to external input. This single case study describes changing patterns of multiple time series that were produced by app-based daily self-assessments during and after an 8-week mindfulness-based stress reduction program. After this MBSR program, the participant (a female nurse) continued the self-assessment and the mindfulness practice for a further 10 months. The results confirm findings on the positive effects of mindfulness programs for healthcare professionals, especially on coping with work-related stress. The analysis of the time series data supports the hypothesis of self-organization as a possible mechanism of change manifesting as a cascade of phase transitions in the dynamics of a biopsychosocial system. At the end of the year, the participant reported a beneficial impact of daily monitoring and systematic feedback on the change process. The results underline the feasibility and usefulness of continuous high-frequency monitoring during and after mindfulness interventions.

Tackling the 'digital pandemic': The effectiveness of psychological intervention strategies in problematic Internet and smartphone use-A meta-analysis.

OBJECTIVE: Problematic Internet and smartphone use is associated with serious mental health problems. We thus investigated the effectiveness of psychological interventions on problematic Internet and smartphone use. METHODS: We conducted a systematic review and meta-analysis and searched in PubMed, PsyArticles, PsycInfo, Medline and Google Scholar for peer-reviewed experimental and quasi-experimental research published between 2008 and 2021. RESULTS: A total of 10 studies accompanied by 14 effect sizes were included in the meta-analyses for problematic Internet use and 3 studies accompanied by 4 effect sizes for problematic smartphone use. The total sample size was n = 1439 with a mean age of 20.34 (SD = 6.63) years. Psychological interventions were effective for both problematic Internet use (g = -1.41, 95% confidence interval = [-1.90, -0.91], p < 0.001) and problematic smartphone use (g = -0.40, 95% confidence interval = [-0.79, -0.01], p < 0.001). CONCLUSION: Current evidence indicates that psychological interventions can be effective in reducing problematic Internet use/problematic smartphone use. However, the results must be considered preliminary due to the limited number of studies available in the respective fields.

Effective Connectivity of the Hippocampus Can Differentiate Patients with Schizophrenia from Healthy Controls: A Spectral DCM Approach.

We applied spectral dynamic causal modelling (Friston et al. in Neuroimage 94:396-407. https://doi.org/10.1016/j.neuroimage.2013.12.009 , 2014) to analyze the effective connectivity differences between the nodes of three resting state networks (i.e. default mode network, salience network and dorsal attention network) in a dataset of 31 male healthy controls (HC) and 25 male patients with a diagnosis of schizophrenia (SZ). Patients showed increased directed connectivity from the left hippocampus (LHC) to the: dorsal anterior cingulate cortex (DACC), right anterior insula (RAI), left frontal eye fields and the bilateral inferior parietal sulcus (LIPS & RIPS), as well as increased connectivity from the right hippocampus (RHC) to the: bilateral anterior insula (LAI & RAI), right frontal eye fields and RIPS. In SZ, negative symptoms predicted the connectivity strengths from the LHC to: the DACC, the left inferior parietal sulcus (LIPAR) and the RHC, while positive symptoms predicted the connectivity strengths from the LHC to the LIPAR and from the RHC to the LHC. These results reinforce the crucial role of hippocampus dysconnectivity in SZ pathology and its potential as a biomarker of disease severity.

Multi-level assessment of obsessive-compulsive disorder (OCD) reveals relations between neural and neurochemical levels.

BACKGROUND: While considerable progress has been made in exploring the psychological, the neural, and the neurochemical dimensions of OCD separately, their interplay is still an open question, especially their changes during psychotherapy. METHODS: Seventeen patients were assessed at these three levels by psychological questionnaires, fMRI, and venipuncture before and after inpatient psychotherapy. Seventeen controls were scanned at comparable time intervals. First, pre/post treatment changes were investigated for all three levels separately: symptom severity, whole-brain and regional activity, and the concentrations of cortisol, serotonin, dopamine, brain-derived neurotrophic factor (BDNF), and immunological parameters (IL-6, IL-10, TNFα). Second, stepwise linear modeling was used to find relations between the variables of the levels. RESULTS: The obsessive-compulsive, depressive, and overall symptom severity was significantly reduced after psychotherapy. At the neural level, the activity in the anterior cingulate cortex (ACC), in frontal regions, in the precuneus, and in the putamen had significantly decreased. No significant changes were found on the neurochemical level. When connecting the levels, a highly significant model was found that explains the decrease in neural activity of the putamen by increases of the concentrations of cortisol, IL-6, and dopamine. CONCLUSION: Multivariate approaches offer insight on the influences that the different levels of the psychiatric disorder OCD have on each other. More research and adapted models are needed.

Non-adherence to psychotropic medication assessed by plasma level in newly admitted psychiatric patients: Prevalence before acute admission.

AIMS: Non-adherence or partial adherence to psychotropic medication is found in 18-70% of patients. Many previously used methods for the assessment of adherence (e.g. questionnaires, pill counts, and electronic systems), however, might underreport actual rates of non-adherence to medication. The aim of this study was to quantify adherence using plasma level. METHODS: We conducted a 6-week prospective study of all consecutive admitted patients at the Paracelsus Medical University of Salzburg, Clinics of Psychiatry and Psychotherapy, who had been treated with antipsychotics/antidepressants prior to admission (pre-medication dosage in 161 of 233). Plasma drug levels were determined and compared with expected levels based on known preadmission dosing regimens and average pharmacokinetic data. RESULTS: Seventy-three percent of the patients had actual plasma levels clearly below or above the intended level. Significantly more patients with schizophrenia (66%) did not take the medication as prescribed, when compared with patients with affective disorders (47%) or those with other psychiatric diagnoses (41%). Only 27% (44 of 161) of the patients had plasma level in the expected range based on the dosage. CONCLUSION: The risk of partial adherence or non-adherence is expected in two-thirds of patients with schizophrenia, half of patients with affective disorders, and approximately 40% of patients with other psychiatric diagnoses. Given that admitting psychiatrists could not provide an accurate assessment of patient adherence, it is strongly suggested that clinical judgment be supplemented with the actual monitoring of adherence - and further optimization of pharmacotherapy - by means of therapeutic drug monitoring.

The Therapy Process Questionnaire - Factor analysis and psychometric properties of a multidimensional self-rating scale for high-frequency monitoring of psychotherapeutic processes.

Many outcome measures and session-related questionnaires in psychotherapy are designed for weekly or biweekly administration. Yet, today, technical developments allow for higher frequency assessments to monitor human change dynamics more closely by daily assessments. For this purpose, the Therapy Process Questionnaire (TPQ) was developed, with a specific focus on inpatient psychotherapy. In this article, we present an explorative and confirmative factor analysis of the TPQ on the basis of the time series data of 150 patients collected during their hospital stay (mean time series length: 69.1 measurement points). A seven-factor solution was identified, which explains 68.7% of variance and associates 43 items onto the factors, which are "well-being and positive emotions," "relationship with fellow patients," "therapeutic relationship and clinical setting," "emotional and problem intensity," "insight/confidence/therapeutic progress," "motivation for change," and "mindfulness/self-care." The internal consistency (Cronbach's α), the inter-item correlations of the subscales, and the discriminative power of the items are excellent. The TPQ can be applied in practice and research for creating time series with equidistant measurement points and time series lengths, which are appropriate for the application of nonlinear analysis methods. Especially in clinical practice, it is important to identify precursors of phase transitions, changing synchronization patterns, and critical or instable periods of a process, which now is possible by internet- or app-based applications of this multidimensional questionnaire.

A Nonlinear Dynamic Systems Model of Psychotherapy: First Steps Toward Validation and the Role of External Input.

Mathematical modeling and computer simulations are important means to understand the mechanisms of psychotherapy. The challenge is to design models which not only predict outcome, but simulate the nonlinear trajectories of change. Another challenge is to validate them with empirical data. We proposed a model on change dynamics which integrates five variables (order parameters) (therapeutic progress or success, motivation for change, problem severity, emotions, and insight) and four control parameters (capacity to enter a trustful cooperation and working alliance, cognitive competencies and mindfulness, hopefulness, behavioral resources). The control parameters modulate the nonlinear functions interrelating the variables. The evolution dynamics of the system is determined by a set of nine nonlinear difference equations, one for each variable and parameter. Here we outline how the model can be tested and validated by empirical time series data of the variables, by time series of the therapeutic alliance, and by assessing the input onto the system as it is perceived by the client. The parameters are measured by questionnaires at the beginning and at the end of the treatment. A key element of the validation algorithm is the adjustment of the parameter values as assessed by the questionnaires to model-specific parameter values by which the dynamics can be reproduced (calibration). The validation steps are illustrated by the data of a client who used an internet-based tool for high-frequency therapy monitoring (daily self-ratings). Especially after applying the input vector (interventions as experienced by the client) the similarity between the empirical and the model dynamics becomes evident. The averaged correlation between the empirical and the simulated dynamics across all variables is .41, after applying a short averaging mean window and eliminating an initial transient period, it is .62, varying between .47 and .81, depending on the variable. The discussion opens perspectives on the combination of mathematical modeling with real-time monitoring in order to realize data-driven simulations for short-term predictions and to estimate the effects of interventions before real interventions are applied.

EEG theta phase coupling during executive control of visual working memory investigated in individuals with schizophrenia and in healthy controls.

In healthy humans, it has been shown that executive functions are associated with increased frontal-midline EEG theta activity and theta phase coupling between frontal and posterior brain regions. In individuals with schizophrenia, central executive functions are supposed to be heavily impaired. Given that theta phase coupling is causally involved in central executive functions, one would expect that patients with an executive function deficit should display abnormal EEG theta synchronization. We therefore investigated executive functioning in 21 healthy controls and 21 individuals with schizophrenia while they performed a visuospatial delayed match to sample task. The task required either high executive demands (manipulation of content in working memory [WM]) or low executive demands (retention of WM content). In addition, WM load (one vs. three items) was varied. Results indicated higher frontal theta activity for manipulation processes than for retention processes in patients with schizophrenia, as compared with healthy controls, independently of WM load. Furthermore, individuals with schizophrenia revealed a reduction in theta phase coupling during early stages of the delay period for retention, as well as for manipulation processes at high-WM loads. Deviations in theta phase coupling in individuals with schizophrenia were mainly characterized by aberrant fronto-posterior connections, but also by attenuated posterior connections during manipulation of high-WM load. To conclude, fronto-parietal theta coupling seems to be substantially involved in executive control, whereas frontal theta activity seems to reflect general task demands, such as deployment of attentional resources during WM.

Pattern transitions in diary data of MDD patients: a mixed-methods multiple case study of psychotherapy dynamics.

Aim: Mixed-methods approaches promise a deep understanding of psychotherapeutic processes. This study uses qualitative and quantitative data from daily diary entries and daily self-assessments during inpatient treatment. The aim of the study is to get an insight into the similarities and differences between both types of data and how they represent self-organized pattern transitions in psychotherapy. While a complete correlation of results is not expected, we anticipate observing amplifying and subsidiary patterns from both perspectives. Materials and methods: Daily, five MDD patients wrote diaries and completed self-assessments using the Therapy Process Questionnaire, a questionnaire for monitoring the change dynamics of psychotherapy. The data were collected using the Synergetic Navigation System, an online tool for real-time monitoring. Diary entries of the patients described their experiences in everyday life. The qualitative text analysis was conducted using Mixed Grounded Theory, which provided categories representing the patients' ongoing experiences of transformation and stagnation. The time series data was analyzed using the dynamic complexity algorithm and the pattern transition detection algorithm. Results from qualitative and quantitative analyses were combined and compared. Following the process of data triangulation, the leading perspective came from the theory of self-organization. In addition to presenting the overall results for all five patients, we delve into two specific case examples in greater detail. Results: Specific and highly diversified diary entries of 5 patients were classified into the categories of perceived pattern stability, noticing improvement, broadening the perspective, critical instability, and experiencing moments of Kairos. Patients reported problems not only related to their disorder (e.g., lack of energy and hopelessness) but also to phases and steps of change, which could be related to the theory of self-organization (e.g., problem attractors, critical fluctuations, pattern transitions, and Kairos). Qualitative and quantitative analysis provide important supplementary results without being redundant or identical. Conclusion: Data triangulation allows for a comprehensive and multi-perspective understanding of therapeutic change dynamics. The different topics expressed in the diary entries especially help to follow micro-psychological processes, which are far from being a simple reaction to interventions. The way patients experience themselves being in stability or instability and stagnation or transformation is surprisingly close to the general features of self-organizing processes in complex systems.

Dynamic association between suicidal ambivalence and suicide risk among individuals with a history of suicide attempts.

OBJECTIVE: Suicide risk is highly fluctuating. There is a need for predictors of short-term change in suicide risk to optimize risk assessment and treatment, especially among individuals who already attempted suicide. METHODS: Based on 1776 daily assessments of 16 former psychiatric inpatients with a history of suicide attempts, we examined how suicidal ambivalence and, respectively, wish to die (WTD) and wish to live (WTL) predicted same-day and change in perceived suicide risk (i.e., next-day perceived suicide risk, controlled for same-day perceived suicide risk) in multilevel regression models. Additionally, based on the assumptions of nonlinear dynamics, we examined the associations between levels of fluctuations in the WTD/WTL and perceived suicide risk within the same time period. RESULTS: Suicidal ambivalence, WTD, and a WTL significantly correlated with same-day suicide risk. Suicidal ambivalence and WTD significantly predicted change in suicide risk. Fluctuations in WTD were significantly associated with concurrent suicide risk. CONCLUSION: The results suggest that suicidal ambivalence and WTD are drivers of suicide risk among individuals who already attempted suicide. The association between fluctuations in WTD and suicide risk was small and warrants further investigation on the practical utility as a warning sign.

Evaluation of a flexible assertive community treatment (FACT) program for patients with severe mental illness: an observational study in Salzburg, Austria.

BACKGROUND: Inpatient treatment of severe mentally ill patients binds substantial resources and creates the dilemma of "revolving-door hospitalizations". Evidence suggests that these patients benefit more from an assertive outreach community psychiatric treatment. This descriptive study evaluates the implementation of a new treatment program for severe mentally ill patients provided by a flexible assertive community treatment (FACT) team. METHODS: An uncontrolled design with routine data was used to measure the total length of stays, readmission rates and number of contacts one year prior to the implementation of the FACT program and the following first three years of treatment. RESULTS: A continuous decrease of hospitalization among patients with severe mental illness was observed with the implementation of the FACT program with declines in total length of stays and readmission rates and accompanied with a decreasing number of contacts per year. CONCLUSION: Our findings indicate that this program may create effects in stabilizing patients with severe mental illness and may be highly relevant also for other patient groups.

[Real-time monitoring of psychotherapeutic change processes]. / Real-Time Monitoring in der Psychotherapie.

Since several years, internet-based technologies for the monitoring of psychotherapy processes were partially established in in-patient and day treatment centres. We discuss the usefulness and some methodological requirements of process monitoring devices, with a more detailed description of the Synergetic Navigation System (SNS). Continuous self-ratings and the use of feedback-tools like the SNS will have therapeutic implications on patients as well as therapists and their professional cooperation with the patient. Studies on the effects of feedback-systems on patients and therapists should be realized, and the quality of feedback-sessions as well as the competencies in the management of nonlinear processes and feedback-systems should be enhanced. Real-time monitoring is ready to get an integrated part of clinical practice and of clinical training programs.

Therapeutic alliance and change in suicide ideation among psychiatric inpatients at risk for suicide.

BACKGROUND: Therapeutic alliance is thought to be essential in the treatment of suicidality. Surprisingly, studies about the association between therapeutic alliance and change in suicide ideation over the course of treatment are sparse and reported inconsistent results. Furthermore, theoretically important moderators were rarely explored empirically. METHODS: We investigated the association between therapeutic alliance and change in suicide ideation (difference between intake and discharge), unadjusted and adjusted for potential confounding variables (diagnoses, sociodemographics etc.) in a sample of 351 inpatients treated in a psychiatric department specialized in crisis intervention and suicide prevention. We also explored if the association was moderated by suicide ideation at intake, history of suicide attempts, and borderline personality disorder (BPD). We ran sensitivity analyses for different diagnostic subgroups, history of suicide attempts, and a quantitative measure of BPD symptoms. RESULTS: We found a moderate association between therapeutic alliance and change in suicide ideation (r = 0.30, p < 0.01). This association remained robust after accounting for potentially confounding variables. Suicide ideation at intake, history of suicide attempts, and BPD were not statistically significant moderators. Sensitivity analyses led to similar results. LIMITATIONS: Therapeutic alliance was assessed only at the end of treatment and causality cannot be inferred from our study method. CONCLUSIONS: Therapeutic alliance was a robust correlate of improvement in suicide ideation among psychiatric inpatients at risk for suicide, independent from diagnostic groups and other patient characteristics. Our results support the crucial role of therapeutic alliance in the treatment of patients at risk for suicide.

Depressive symptoms are more influenced by personality traits and styles than working in nursing-a study during the COVID-19 pandemic.

Background: According to literature, the COVID-19 pandemic caused stressful working conditions for nurses, which may have a negative impact on their Well-Being and mental health. Aim: To investigate whether nurses and non-helping professionals differ in their Well-Being. Furthermore, we analyzed, for the first time, which personality traits and styles are a risk factor for nurses' wellbeing during COVID-19 pandemic. Methods: In an online survey, the following psychological tests were used on nursing staff (n = 518) and non-helping professionals (n = 335): WHO-Five (WHO-5), the Personality, Style and Disorder Inventory (PSSI), and the Freiburg Personality Inventory-Revised (FPI-R). Results: Nurses and non-helping professionals did not differ significantly in terms of Well-Being. The Well-Being of nurses was correlated with the following personality traits and styles, namely Spontaneous-Borderline Personality Style, Silent-Depressive Personality Style, Strain, Emotionality, and Life Satisfaction. According to our results, 33% of participants suffered from clinically significant depressive symptoms. Discussion: According to our results, nurses are not more at risk for depression. However, it was shown that Well-Being during the pandemic is highly dependent on personality. Conclusion: Specific personality traits and styles are a greater predictor of depressive symptoms than profession. The stressful occupational environment during COVID-19 pandemic is not the only cause for depressive symptoms in nurses. Psychotherapeutic interventions are especially important for particular individuals and are necessary to prevent depressive symptoms during COVID-19 pandemic.

Helper Syndrome and Pathological Altruism in nurses - a study in times of the COVID-19 pandemic.

Background: Pathological Altruism and the concept of Helper Syndrome are comparable. We focused on Schmidbauer's description because it provides a comprehensive and testable definition. Nevertheless, this concept of Helper Syndrome has not yet been empirically investigated in a sample of helping professionals. Aim: To investigate whether nurses working with covid-19 patients are more likely to have Helper Syndrome compared with individuals from non-helper professions. Methods: The online survey took place between April 2021 and February 2022, in urban and rural regions of Salzburg, during the time of the COVID-19 pandemic. Nurses (n = 447) and controls (n = 295) were compared regarding Helper Syndrome characteristics. To measure characteristics of Helper Syndrome the following questionnaires were used: WHO-Five (WHO-5), selected scales of the Personality, Style and Disorder Inventory (PSSI) and the Freiburg Personality Inventory-Revised (FPI-R), the Alcohol Use Disorders Identification Test (AUDIT). Insecure gender identity and self-assessment of having a Helper Syndrome was measured by a Likert scale. Results: In both groups, Helper Syndrome was detected (nurses 29.5%, controls 30.5%). Participants with Helper Syndrome showed significant differences in personality styles and traits, namely significantly higher scores for Foreboding-Schizotypical Personality Style, Spontaneous-Borderline Personality Style, Amiable-Histrionic Personality Style, Ambitious-Narcissistic Personality Style, Loyal-Dependent Personality Style, Helpful-Selfless Personality Style, Carefully-Obsessive Personality Style, Optimistic-Rhapsodic Personality Style, Social Orientation, Strain, Emotionality and lower well-being. The only difference between nurses and controls was that nurses were significantly less open aggressive. Conclusion: For the first time, we were able to demonstrate Schmidbauer's concept of Helper Syndrome. According to our data, we found a subgroup of individuals similar to Schmidbauer's description of Helper Syndrome, but this sample was independent of helping or non-helping profession. These individuals seem to be at higher risk for psychiatric disorders.

[Therapy Process Questionnaire (TPQ) - a combined explorative and confirmatory factor analysis and psychometric properties]. / Der Therapie-Prozessbogen (TPB) ­ faktorenstruktur und psychometrische daten.

OBJECTIVES: This contribution looks at the factorial structure of the Therapy Process Questionnaire (TPQ), which is used for daily self-ratings of patients tested by internet-based ambulatory assessment devices. METHODS: A combined explorative and confirmatory factor analysis of the TPQ. The time-series data were generated by 149 patients treated in an inpatient setting. RESULTS: 23 out of 42 items included in the explorative version of the TPQ are represented onto five factors, which were identified by a first explorative factor analysis and then validated by a confirmative factor analysis. We report on the psychometric data of the subscales: internal consistency (Cronbach's α), mean of item-intercorrelation, and mean of item discrimination indices. CONCLUSION: The TPQ is useful for a high-frequency and equidistant (daily) assessment of psychotherapeutic change processes.

Psychological online interventions for problem gambling and gambling disorder - A meta-analytic approach.

OBJECTIVE: The Covid-19 pandemic has reignited discussions about the prevalence of and treatment options for problem gambling and gambling disorder (PGGD). Since affected persons seldom seek professional help, online interventions can improve accessibility. Thus, this study aimed to investigate the effectiveness of psychological online interventions on PGGD. METHODS: We conducted a systematic review and meta-analysis and searched in PubMed, PsycINFO, and Google Scholar for peer-reviewed experimental and quasi-experimental research published between 2010 and 2021. We calculated two meta-anlyses, one for treatment control comparisons (TCC), and one for pre-post-comparisons (PCC). RESULTS: We included six studies (ten TCC and n = 2076) in meta-analysis 1 and five studies (six PCC and n = 781) in meta-analysis 2. Online interventions turned out to be effective in both analyses with Hedges g = 0.41, 95% confidence interval = [0.22 to 0.60], p < .001, for meta-anaylsis 1 and Hegdes g = 1.28, 95% confidence interval = [0.85 to 1.71], p < .001, for meta-analysis 2. CONCLUSIONS: We identified significant effects of online interventions on PGGD in both analyses, indicating the potential of online applications. We discuss methodological aspects and further research directions.

Personality traits and complex problem solving: Personality disorders and their effects on complex problem-solving ability.

Complex problem solving (CPS) can be interpreted as the number of psychological mechanisms that allow us to reach our targets in difficult situations, that can be classified as complex, dynamic, non-transparent, interconnected, and multilayered, and also polytelic. The previous results demonstrated associations between the personality dimensions neuroticism, conscientiousness, and extraversion and problem-solving performance. However, there are no studies dealing with personality disorders in connection with CPS skills. Therefore, the current study examines a clinical sample consisting of people with personality and/or depressive disorders. As we have data for all the potential personality disorders and also data from each patient regarding to potential depression, we meet the whole range from healthy to impaired for each personality disorder and for depression. We make use of a unique operationalization: CPS was surveyed in a simulation game, making use of the microworld approach. This study was designed to investigate the hypothesis that personality traits are related to CPS performance. Results show that schizotypal, histrionic, dependent, and depressive persons are less likely to successfully solve problems, while persons having the additional behavioral characteristics of resilience, action orientation, and motivation for creation are more likely to successfully solve complex problems.
