RESUMO
Psychological stress is the most commonly self-reported precursor of epileptic seizures. However, retrospective and prospective studies remain inconclusive in this regard. Here, we explored whether seizures would be preceded by significant changes in reported stressors or resource utilization. This study is based on high-frequency time series through daily online completion of personalized questionnaires of 9-24 items in epilepsy outpatients and compared responses 1-14 days before seizures with interictal time series. Fourteen patients (79% women, age = 23-64 years) completed daily questionnaires over a period of 87-898 days (median = 277 days = 9.2 months). A total of 4560 fully completed daily questionnaires were analyzed, 685 of which included reported seizure events. Statistically significant changes in preictal compared to interictal dynamics were found in 11 of 14 patients (79%) across 41 items (22% of all 187 items). In seven of 14 patients (50%), seizures were preceded by a significant mean increase of stressors and/or a significant mean decrease of resource utilization. This exploratory analysis of long-term prospective individual patient data on specific stressors and personal coping strategies generates the hypothesis that medium-term changes in psychological well-being may precede the occurrence of epileptic seizures in some patients.

We face increasing demand for greater access to effective routine mental health services, including telehealth. However, treatment outcomes in routine clinical practice are only about half the size of those reported in controlled trials. Progress feedback, defined as the ongoing monitoring of patients' treatment response with standardized measures, is an evidence-based practice that continues to be under-utilized in routine care. The aim of the current review is to provide a summary of the current evidence base for the use of progress feedback, its mechanisms of action and considerations for successful implementation. We reviewed ten available meta-analyses, which report small to medium overall effect sizes. The results suggest that adding feedback to a wide range of psychological and psychiatric interventions (ranging from primary care to hospitalization and crisis care) tends to enhance the effectiveness of these interventions. The strongest evidence is for patients with common mental health problems compared to those with very severe disorders. Effect sizes for not-on-track cases, a subgroup of cases that are not progressing well, are found to be somewhat stronger, especially when clinical support tools are added to the feedback. Systematic reviews and recent studies suggest potential mechanisms of action for progress feedback include focusing the clinician's attention, altering clinician expectations, providing new information, and enhancing patient-centered communication. Promising approaches to strengthen progress feedback interventions include advanced systems with signaling technology, clinical problem-solving tools, and a broader spectrum of outcome and progress measures. An overview of methodological and implementation challenges is provided, as well as suggestions for addressing these issues in future studies. We conclude that while feedback has modest effects, it is a small and affordable intervention that can potentially improve outcomes in psychological interventions. Further research into mechanisms of action and effective implementation strategies is needed.
RESUMO
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.
RESUMO
BACKGROUND: Even though recent research indicates that sexual symptoms are highly prevalent in post-traumatic stress disorder following childhood sexual abuse and cause severe distress, current treatments neither address them nor are they effective in reducing them. This might be due to a lack of understanding of sexual symptoms' specific role in the often complex and comorbid psychopathology of post-traumatic stress disorder following childhood abuse. METHODS: Post-traumatic, dissociative, depressive, and sexual symptoms were assessed in 445 inpatients with post-traumatic stress disorder following childhood sexual abuse. Comorbidity structure was analyzed using a partial correlation network with regularization. RESULTS: A total of 360 patients (81%) reported difficulties engaging in sexual activities and 102 patients (23%) reported to suffer from their sexual preferences. Difficulties engaging in sexual activities were linked to depressive and hyperarousal symptoms, whereas sexual preferences causing distress were linked to anger and dissociation. Dissociative amnesia, visual intrusions, and physical reactions to trauma reminders were of central importance for the network. Dissociative amnesia, depressed mood, lack of energy, and difficulties engaging in sexual activities were identified as bridge symptoms. Local clustering analysis indicated the non-redundancy of sexual symptoms. CONCLUSIONS: Sexual symptoms are highly prevalent in survivors of childhood sexual abuse with post-traumatic stress disorder. Further research is needed regarding the link of difficulties engaging in sexual activities, depression, and post-traumatic stress disorder, as well as regarding the association of dissociation and sexual preferences causing distress. Sexual symptoms require consideration in the treatment of post-traumatic stress disorder following childhood sexual abuse.

OBJECTIVE: Therapeutic process factors including alliance and motivation are considered to play a key role in the treatment of post-traumatic stress disorder (PTSD). Yet, our understanding of change processes in therapy is mostly based on theoretical considerations with limited empirical evidence. In order to identify process characteristics of successful inpatient treatments of PTSD, we investigated the intraindividual, interindividual, and temporal associations of daily assessments of therapy process factors like motivation, alliance, and insight. METHOD: Therapy process questionnaire (TPQ) assessments were collected from 101 inpatients with PTSD over 50 days, resulting in 5050 assessments. Multilevel vector autoregressive (mlVAR) modelling was applied to investigate the networks of the TPQ factors in a subgroup with good outcome regarding PTSD symptomatology and a subgroup with less favourable outcome. RESULTS: The two subgroups differed markedly in their network models, suggesting that therapy processes might be different for those with good and those with poor treatment outcomes. CONCLUSIONS: Our results suggest that good treatment outcome is linked to a specific therapy process dynamic where mindfulness and insight lead to the kind of temporary well-being required to effectively engage with problems and negative emotions, while motivation to change ensures the continuity of confronting negative emotions and problems.

BACKGROUND: This feasibility study applied the concept of daily systematic monitoring of personalized psychological variables and investigated patients' compliance in order to evaluate if its integration in outpatient psychotherapy is feasible and if patients found the development and daily application of personalized questionnaires user-friendly and useful. METHODS: A naturalistic sample of patients with epilepsy (PWE) was enrolled to participate in an outpatient psychotherapy program. A personalized process questionnaire was developed with each patient based on an individual psychological system's model at the outset of therapy. Daily time-stamped self-assessments were collected during outpatient psychotherapy. This process-monitoring was technically realized by an internet-based device for data collection and data analysis, the Synergetic Navigation System (SNS). The reflection of person-specific time series informed by patients' replies to their personalized process questionnaire was integrated in the therapy process. Compliance rates were assessed during a period of six months (i.e., 180â¯days) after the first entry of the questionnaire [compliance rateâ¯=â¯(number of completed questionnaires/180)â¯×â¯100]. User-friendliness and usefulness of this process monitoring were evaluated quantitatively. RESULTS: Twenty patients [15 women/5 men, median age 48â¯years (range 23-73â¯years)] were recruited. Compliance rates were high (median: 93%, range 31-100%) among the participants. Participants reported a high overall satisfaction with the application and user-friendliness of SNS. CONCLUSION: The results support the feasibility of high-frequency monitoring of personalized psychological processes during outpatient psychotherapy. Repeated daily assessments of a personalized questionnaire yield highly resolved, equidistant time series data, which gives insight into individual psychological processes during outpatient psychotherapy.

BACKGROUND: There is great scientific and clinical interest in the effective integration of psychological treatments into comprehensive epilepsy care to optimize treatment outcomes and psychosocial functioning in people with epilepsy. Stepped care is a promising approach to accommodate personalized psychotherapeutic care in academic and regular outpatient settings. It aims at providing patients with the most adequate treatment duration, number of sessions, and treatment method while systematically monitoring their treatment processes. METHODS: This is an uncontrolled feasibility study of process-oriented and personalized psychotherapeutic care for epilepsy in a naturalistic setting. The objective of this study was to evaluate individual changes of health-related quality of life (QOLIE-31) and psychiatric comorbidity (BDI-II, BSI) in participants by applying the concept of the reliable change index (RCI) to outcomes that were obtained at baseline and six months after the beginning of the intervention. Additionally, we assessed the relationship between outcome scores, the number of attended sessions, and history of childhood trauma by linear regression models. RESULTS: Twenty patients [15 women/5 men, median age 48â¯years (range: 23-73â¯years)] were recruited. The median number of scheduled sessions was 11 (range: 6-22); there were no drop-outs. After psychotherapy quality of life (QOLIE-31), global distress (BSI) and depression (BDI-II) scores improved significantly (p-values: QOLIE-31: 0.03; BSI: 0.01; BDI-II: 0.01). The largest improvements were achieved for the emotional well-being subscale of the QOLIE-31 (47%, p-value: 0.02), the global severity index of the BSI (83%), and depression severity (BDI-II) (60%). Linear regression models did not reveal any significant association between interim changes, number of attended treatment sessions, and history of childhood trauma. CONCLUSION: The results suggest that process-oriented and personalized psychotherapeutic has low attrition and results in improved quality of life and reduced psychiatric symptoms in people with epilepsy. Our findings indicate that responsiveness to psychotherapy is not dependent on the number of attended treatment sessions. Participants with childhood trauma did not need more treatment sessions to achieve an improvement. More research is needed to understand and address mechanisms and precursors of responsiveness to psychotherapy.
RESUMO
Objective: To assess the outcome of psychotherapeutic treatments, psychotherapy researchers often compare pre- and post-treatment scores on self-report outcome measures. In this paper, the common assumption is challenged that pre-to-post decreasing and increasing outcome scores are indicative of successful and failed therapies, respectively.Method: The outcome of 29 psychotherapeutic treatments was evaluated by means of quantitative analysis of pre- and post-treatment scores on commonly used outcome measures (such as the Symptom Checklist-90-R, the Inventory of Interpersonal Problems, and the General Health Questionnaire-12), as well as through consensual qualitative research.Results: Overall, a moderate to low convergence between qualitative and quantitative evaluations of outcome was observed. Detailed analyses of six cases are presented in which pre-to-post comparisons of outcome measures proved misleading.Conclusions: It is concluded that psychotherapy outcome research might benefit from assessment strategies that are sensitive to the singularities of individual treatments and to the complexity of the phenomenon of therapeutic outcome. Furthermore, classical psychometric evaluations of the validity of outcome measures might be supplemented with less-systematic evaluations that take any contingent source of information on outcome into account.

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.

Objective: While destabilization periods characterized by high variability and turbulence in a patient's psychological state might seem obstructive for psychotherapy, a complex systems approach to psychopathology predicts that these periods are actually beneficial as they indicate possibilities for reorganization within the patient. The present study tested the hypothesis that destabilization is related to better treatment outcome.Method: 328 patients who received psychotherapy for mood disorders completed daily self-ratings about their psychotherapeutic process. A continuous measure of destabilization was defined as the relative strength of the highest peak in dynamic complexity, a measure for variability and turbulence, in the self-ratings of individual patients.Results: Destabilization was found to be related to better treatment outcome. When improvers and non-improvers were analyzed separately, destabilization was found to be related to better treatment outcome in improvers but not in non-improvers.Conclusions: Destabilization in daily self-ratings of the psychotherapeutic process is associated with better treatment outcome. The identification of destabilization periods in process-monitoring data is clinically relevant. During destabilization, patients are believed to be increasingly sensitive to the effects of therapy. Clinicians could tailor their interventions to these sensitive periods.

At the level of individual experience, the relation between electroencephalographic (EEG) phenomena and subjective ratings of psychological states is poorly examined. This study investigated the correlation of quantitative EEG markers with systematic high-frequency monitoring of psychological states in patients admitted to the epilepsy monitoring unit (EMU). We used a digital questionnaire, including eight standardized items about stress, energy level, mood, ward atmosphere, seizure likelihood, hopefulness/frustration, boredom, and self-efficacy. Self-assessments were collected four times per day, in total 15 times during the stay in the EMU. We extracted brainrate, Hjorth parameters, Hurst exponent, Wackermann parameters, and power spectral density from the EEG. We performed correlation between these quantitative EEG measures and responses to the 8 items and evaluated their significance on single subject and on group level. Twenty-one consecutive patients (12 women/9 men, median age: 29 years, range: 18-74â¯years) were recruited. On group level, no significant correlations were found whereas on single-subject level, we found significant correlations for 6 out of 21 patients. Most significant correlations were found between Hjorth parameters and items that reflect changes in mood or stress. This study supports the feasibility of correlating quantitative EEG measures with psychological states in routine EMU settings and emphasizes the need for single-subject statistics when assessing aspects with high interindividual variance. Future studies should select samples with high within-subject variability of psychological states and examine a subsample with patients encountering a critical number of seizures needed in order to relate the psychological states to the ultimate question: Are psychological states potential indicators for seizure likelihood?

BACKGROUND: There is a lack of studies investigating the effectiveness of inpatient trauma-focused psychotherapy of complex post-traumatic stress disorder. The first aim of this retrospective investigation was to analyze the course of PTSD. Second, possible predictors of treatment response were investigated. METHODS: 150 inpatients of Clinic St. Irmingard with complex PTSD following childhood physical and childhood sexual abuse were assessed regarding childhood abuse, PTSD symptomatology, mindfulness, dissociation and general psychopathology. Differences in pre and post scores were analyzed using regression analyses. A classification tree was used to identify predictors of response. RESULTS: The significant reduction of PTSD symptoms corresponded to a large effect (d=1.8) and a reponse rate of 52% according to the reliable change index (p<0.05). Effect sizes for other symptoms were medium to large (0.5Assuntos

RESUMO
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.

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.

BACKGROUND: Admission to the epilepsy monitoring unit (EMU) for long-term video-electroencephalography (EEG) monitoring (VEEG) constitutes the gold standard for seizure diagnosis and presurgical evaluation. This study applied the concept of a high-frequency systematic monitoring of psychological states and tested patients' compliance in order to evaluate if its integration in the EMU is feasible and if patients benefit from the graphically underpinned discussion of their EMU stay-related cognitions and emotions. METHODS: The process-monitoring is technically realized by an internet-based device for data collection and data analysis, the Synergetic Navigation System (SNS). A convenient sample was enrolled: All eligible patients who were admitted to the EMU of the Department of Neurology, Christian Doppler Medical Center, Salzburg, Austria, between November 6th 2017 and January 26th 2018 were approached and recruited upon consent. After a short resource-oriented interview, each enrolled patient was provided with a tablet. The daily questionnaire included eight standardized and up to three personalized items. Self-assessments were collected every 5â¯h prior to meal times (6:30â¯am, 11:30â¯am, and 4:30â¯pm) and at 9:30â¯pm. The detailed visualizations of the patients' replies were discussed with the participants during a feedback session at the end of the EMU stay. RESULTS: Twenty-one patients (12 women/9 men, median age 29â¯years [range 18-74â¯years]) were consecutively recruited (72% of all eligible patients). Compliance rates were high (median: 82%, range 60%-100%) among the respondents. Mood correlated strongly with hopefulness (râ¯=â¯0.71) and moderately with energy (râ¯=â¯0.63) in all patients. When correlating the intraindividual medians of the process questionnaire time series with the pretest total scores, energy correlated moderately and negatively with the Perceived Stress Scale (PSS) (râ¯=â¯-0.45), while self-efficacy correlated moderately and negatively with the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) total scores in all patients (râ¯=â¯-0.5). Nine patients (43%) reported that they learned something meaningful about themselves after the feedback discussion of their individual time series. CONCLUSION: The results support the feasibility of high-frequency monitoring of psychological states and processes in routine EMU settings. Repeated daily collections four times per day of psychological surveys allow for the assessment of highly resolved, equidistant time series data, which gives insight into psychological states and processes during EMU admission.

Psychotherapy is a dynamic process produced by a complex system of interacting variables. Even though there are qualitative models of such systems the link between structure and function, between network and network dynamics is still missing. The aim of this study is to realize these links. The proposed model is composed of five state variables (P: problem severity, S: success and therapeutic progress, M: motivation to change, E: emotions, I: insight and new perspectives) interconnected by 16 functions. The shape of each function is modified by four parameters (a: capability to form a trustful working alliance, c: mentalization and emotion regulation, r: behavioral resources and skills, m: self-efficacy and reward expectation). Psychologically, the parameters play the role of competencies or traits, which translate into the concept of control parameters in synergetics. The qualitative model was transferred into five coupled, deterministic, nonlinear difference equations generating the dynamics of each variable as a function of other variables. The mathematical model is able to reproduce important features of psychotherapy processes. Examples of parameter-dependent bifurcation diagrams are given. Beyond the illustrated similarities between simulated and empirical dynamics, the model has to be further developed, systematically tested by simulated experiments, and compared to empirical data.

We studied the synchronization dynamics of a therapist and patient during a psychotherapy session. This investigation was developed in order to explore a new possible perspective and methodology for studying the expression of emotions. More specifically, literature concerning synchronization of in-session non-verbal variables emphasises its positive correlation with empathy and therapeutic outcomes. We compared the dynamics of galvanic skin response (GSR) and linguistic prosody, chosen as indicators of emotional expression in different domains. We studied their synchronization through complementary methodologies: Recurrence Quantification Analysis (RQA) and Principal Component Analysis (PCA), Markov Transition Matrix (MTM) and Cross-Recurrence Quantification Analysis (CRQA). We investigated the nonlinearity of GSR in terms of self-similarity and power-law, as emerged in autocorrelation functions and signal variations. We considered time-lagged correlations as a measure of dynamical systems' memory. This article concludes by highlighting the importance of a deeper study of all variables related to the psychotherapeutic process and their synchronization in order to extend our knowledge of general human dynamics.

In therapy processes of a variety of disorders, discontinuous trajectories of symptom changes have been identified. In this study, we are reporting on such 'sudden gains' that occur in the treatment of clients with obsessive-compulsive disorder (OCD) following cognitive-behavioral group therapy. Time series analysis of data taken from 18 OCD clients revealed that a discontinuously shaped symptom reduction took place already before exposure/response prevention (ERP) in a large number of clients. Coincidently with the steepest gradient of symptom change an increased level of dynamic complexity in daily ratings of 47 items of a specific change questionnaire was observed. Our results support hypotheses from the theory of complex self-organizing systems, postulating nonstationarity and critical instabilities during order transitions. Our study underlines the usefulness of real-time monitoring procedures with high-frequency ratings (daily measurements) in therapeutic routine practice.

The use of ambulatory assessments (AAs) as an approach to gather self-reported questionnaires or self-collected biochemical data is constantly increasing to investigate the experiences, states, and behaviors of individuals and their interaction with external situational factors during everyday life. It is often implicitly assumed that data from different sampling protocols can be used interchangeably, despite them assessing processes over different timescales in different intervals and at different occasions, which depending on the variables under study may result in fundamentally different dynamics. There are multiple temporal parameters to consider and while there is an abundance of sampling protocols that are applied regularly, to date, there is only limited empirical background on the influence different approaches may have on the data and findings. In this review, we aim to give an overview of commonly used types of AA in psychology, psychiatry, and biobehavioral research with a breakdown by temporal design parameters. Additionally, we discuss potential advantages and pitfalls associated with the various approaches. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
