Objective: Dynamic systems theory and complexity theory (DST/CT) is a framework explaining how complex systems change and adapt over time. In psychotherapy, DST/CT can be used to understand how a person's mental and emotional state changes during therapy incorporating higher levels of complexity. This study aimed to systematically review the variability of DST/CT methods applied in psychotherapy research.

Methods: A primary studies search was conducted in the EBSCO and Web of Knowledge databases, extracting information about the analyzed DST/CT phenomena, employed mathematical methods to investigate these phenomena, descriptions of specified dynamic models, psychotherapy phenomena, and other information regarding studies with empirical data (e.g., measurement granularity).

Results: After screening 38,216 abstracts and 4,194 full texts, N = 41 studies published from 1990 to 2021 were identified. The employed methods typically included measures of dynamic complexity or chaoticity. Computational and simulation studies most often employed first-order ordinary differential equations and typically focused on describing the time evolution of client-therapist dyadic influences. Eligible studies with empirical data were usually based on case studies and focused on data with high time intensity of within-session dynamics.

Conclusion: This review provides a descriptive synthesis of the current state of the proliferation of DST/CT methods in the psychotherapy research field.

Objective: Facilitative interpersonal skills (FIS) are a promising variable to explain the so-called therapist effect. We aimed to investigate associations between observer-rated interpersonal skills and self-reported personal characteristics of future therapists.

Method: In this cross-sectional observational study, psychology students and trainee therapists completed self-report personality and sociodemographic questionnaires as well as the FIS Performance Task (German version, observer-rated). Mixed multilevel model analysis was conducted with FIS total mean score (mean value of 312 individual ratings [13 video-clips, 8 FIS-items, 3 raters]) as dependent variable, therapist ID and FIS clip ID as random effects and 15 therapist variables as fixed effects.

Results: In the present sample consisting of 177 participants (age: M = 29.8 years (SD = 7.3), [18,59]; 79.1% female, 20.9% male) greater therapists' experience level, male gender and lower levels of alexithymia were predictive for higher FIS score when statistically controlling for other therapist variables in the model. Age, self-reported childhood maltreatment, attachment style, emotion regulation and self-concept variables turned out to be unrelated.

Conclusion: The results can inform psychotherapy training programs. They specifically support the importance of addressing therapists' potential difficulties in recognizing and verbalizing emotions. This is in line with theoretical literature on alliance ruptures and premises of the Alliance-focused training.

Objectives There is evidence to suggest that only 2-4 weeks of mindfulness-based interventions (MBIs) can already alleviate emotional stress. The current studies sought to examine whether experiential avoidance mediated the effects of MBIs on emotional distress during an early stage of the intervention. Methods: Chinese participants with high emotional distress were recruited. Study 1 included 324 participants, randomly assigned to an online MBI (N = 171) or a control group (N = 153). Experiential avoidance and general emotional distress were measured at baseline and after the 3rd week of the intervention. Study 2 included 158 participants, randomly assigned to an online MBI (N = 79) or a control group (N = 79). Experiential avoidance and emotional distress were measured at baseline and weekly in the first three weeks. Results: Compared to the control group, experiential avoidance and emotional distress were significantly improved in the MBI group during the first three weeks of the intervention (Cohen's d = 0.22-0.63). Moreover, changes in experiential avoidance mediated the effects of MBI on emotional distress in the early stage in both contemporary and lagged mediation models. Discussion: Experiential avoidance is an important mediator during the early-stage of MBIs for alleviating emotional distress.

Objectives: Real relationship (RR) refers to a genuine human relationship between client and therapist, that has been found to be positively related to treatment outcome, and to predict unique variance in outcome over and above the working alliance. However, thus far, the measurement of RR has been limited to self-report. We aimed to develop an observer-rated version of the RR measure (RR-O) to assess RR in therapy sessions.

Methods: We adapted items from the self-report measures to an observer rated measure, which was reviewed by RR experts. The final 24-item RR-O was rated in 540 session transcripts from 27 psychoanalytic treatments that already had existing process and outcome scores.

Results: The RR-O showed good internal consistency and good interrater reliability. In hierarchical EFA, items clustered into a general RR factor, and client realism, client genuineness, therapist genuineness, and therapist realism group factors. In addition, the RR-O was positively related to another RR measure and to the therapeutic alliance.

Conclusion: The RR-O shows initial reliability and validity as an observer-rated measure of the RR to be used in post-hoc psychotherapy research. Future research should clarify the relation between RR-O and treatment outcome.

Objective: The present paper focuses on therapist responsiveness during the initial therapy session with clients with borderline personality disorder (BPD), aiming to analyze therapist responsiveness at short intervals during the initial session and determine if it can predict therapeutic alliance from both therapist and client viewpoints.

Method: A sample of 47 clients participated in the study for 10 sessions of therapy. Therapeutic alliance from therapists' and clients' perspectives was rated after each session; external raters assessed therapist responsiveness during the initial session. Multiple linear regression models and linear mixed models with backward variable selection based on AIC were run to analyze whether specific therapist behaviors during session one predicted therapeutic alliance rated from therapists' and clients' perspectives.

Results: The results indicate that therapists normalizing and validating clients' experiences during the first session are crucial for establishing therapeutic alliance for BPD clients; however, for therapists, the increase in variability of emotions verbalized by clients during the initial session negatively impacts therapeutic alliance.

Conclusion: The study contributes to further understand the impact of therapists' behavior at the beginning of therapy with BPD clients. Therapist responsiveness is crucial for therapy outcome but is methodologically challenging; therefore, efforts in this direction should be pursued.

Objective: The network approach implies that the persistence of a mental disorder is rooted in a dense causal interconnection of symptoms. This study attempts to replicate and generalize previous findings in support of the assumption that higher density predicts poorer outcomes. The study examines the predictive value of network density at admission for recovery after inpatient treatment.

Method: N = 1375 adult patients with various forms of mental illness were classified as recovered (28%) versus not recovered (72%) after inpatient treatment. Recovery was defined as clinically significant improvement in impairment from admission to discharge. Networks of transdiagnostic symptoms at the time of admission were estimated. Network density, measured by global strength d, was compared between the recovered and not recovered groups using a permutation test.

Results: Global strength at the time of admission tended to be higher in the No-Recovery group (d = 10.83) than the Recovery group (d = 7.53) but the association was not significant (p = .12). Similar results were found after controlling for group size and symptom severity.

Conclusion: The predictive value of network density for treatment outcomes remains unclear. There might be structural differences between the groups that the current measure of network density does not adequately represent.

Objective: Eating disorders (EDs) take a life every 52 minutes and treatments are ineffective for ∼50% of individuals. Though EDs are heterogeneous illnesses, current evidence-based treatments take a "one-size-fits-all" approach. Network-Informed Personalized Treatment is a new promising treatment for EDs, but clinician-patient-friendly software tools are needed to integrate this guidance system into routine treatment. Adoption is key for impact, necessitating the inclusion of clinicians in the software development. The current pilot assessed a new data-driven clinician-guidance therapeutic.

Method: A two-part pilot was analyzed for quantitative (0-not at all to 10-extremely) and qualitative input on user perception through quantitative and open-ended prompted questions evaluating using personalizing ED treatment with the Awaken Digital Guide therapeutic.

Results: Results demonstrated that clinicians in a focus group (N = 9) and clinician/patient dyads within implementation (N = 10) endorsed improved efficiency, effectiveness, self-awareness, and accuracy using Awaken Digital Guide compared to current treatment as suggested by quantitative and qualitative results. Both clinicians and patients rated the tool positively (6.8-9.6/5.8-8.6, respectively) with an average rating of good and excellent.

Conclusion: Findings suggest that ED-specialized clinicians desire data-driven guidance on personalizing ED treatment. Users perceive Awaken Digital Guide therapeutic with potential to increase collaboration, motivation, efficiency, and effectiveness of ED personalized treatment.

Brief cognitive behavior therapy (bCBT) is effective in reducing symptoms of depression and anxiety disorders and improving health-related quality of life (HRQoL). However, the mechanisms through which cognitive behavior therapy impact HRQoL are not well understood. This study evaluated whether anxiety and depression symptom reduction is a mechanism of treatment for HRQoL outcomes.

Method: Using secondary data from a multisite, pragmatic, randomized trial, this study evaluated bCBT vs enhanced usual care in 16 VA community-based outpatient clinics. Ordinary least-squares path analysis testing multiple mediators was used to evaluate the role of change in depression and anxiety symptoms in the relationship between treatment condition and HRQoL.

Results: Receiving bCBT (vs. enhanced usual care) was significantly negatively associated with change (reduction) in depression and anxiety scores. The indirect effect of treatment on mental HRQoL was significant with change in depression scores as mediator. A similar pattern was observed for physical HRQoL and change in anxiety scores as mediator.

Conclusion: Findings suggest reduction of depression and anxiety symptoms as a mechanism through which bCBT for depression promoted improvements in HRQoL, with important implications for understanding how CBT impacts functioning, as well as the utility of bCBT in nontraditional mental health settings.

Objective: This exploratory study investigated the association between interpersonal movement and physiological synchronies, emotional processing, and the conversational structure of a couple therapy session using a multimodal, mixed-method approach.

Method: The video recordings of a couple therapy session, in which the participants' electrodermal activity was recorded, were analyzed. The session was divided into topical episodes, a qualitative analysis was conducted on each topical episode's emotional aspects, conversational structure and content. In addition, movement and physiological synchrony were calculated in each topical episode. Regression models were used to discover the associations between qualitative variables and synchronies.

Results: Physiological synchrony was associated with the emotional aspects of the session and to episodes in which the spouses' relationship was addressed, while movement synchrony was only related to emotional valence. No association between synchrony and conversational structure was found.

Conclusion: The findings suggest that physiological and movement synchrony play distinct roles in psychotherapy. The exploratory study sheds light on the association between momentary synchrony, emotions, and conversational structure in a couple therapy session.

Objective: To test the predictive accuracy and generalisability of a personalised advantage index (PAI) model designed to support treatment selection for Post-Traumatic Stress Disorder (PTSD).

Method: A PAI model developed by Deisenhofer et al. (2018) was used to predict treatment outcomes in a statistically independent dataset including archival records for N = 152 patients with PSTD who accessed either trauma-focussed cognitive behavioural therapy or eye movement desensitisation and reprocessing in routine care. Outcomes were compared between patients who received their PAI-indicated optimal treatment versus those who received their suboptimal treatment.

Results: The model did not yield treatment specific predictions and patients who had received their PAI-indicated optimal treatment did not have better treatment outcomes in this external validation sample.

Conclusion: This PAI model did not generalise to an external validation sample.
