RESUMEN
OBJECTIVE: This study investigated whether distinct types of psychotherapy activities, the client's preference towards these activities prior to therapy, and the degree of match between client preferences and therapy activities, served as predictors of treatment outcomes. METHODS: A total of 621 clients (Mage = 42 years, 71.7% female) received individual psychotherapy by 54 psychologists. Associations between activity preferences, therapy activities, and preference-activity match as predictors, and symptom change and treatment dropout as outcomes were analyzed using multilevel longitudinal and logistic modelling and polynomial regression models with response surface analysis. RESULTS: No type of therapy activity or activity preference significantly predicted symptom change in therapy, while higher levels of inward orientation therapy activities predicted an increased risk of dropout. Moreover, matching and higher levels of inward orientation and affect expression activities predicted an increased risk of dropout, and matching and higher levels of outward orientation activities predicted a decreased risk of dropout. Finally, a preference-activity mismatch in affect suppression predicted an increased risk of dropout from therapy, both at higher and lower levels of affect suppression. CONCLUSION: Distinct types of therapy activity preferences may, especially when (mis)matched with similar levels of the same therapy activities, differentially predict particular dropout from therapy.Trial registration: ClinicalTrials.gov identifier: NCT05630560.
RESUMEN
In recent years, there has been increasing interest in utilizing time-lagged panel models to study mechanisms of change in psychotherapy. These models offer valuable insights into the dynamic relationships between variables over time and offer stronger causal inference capabilities than cross-sectional analyses. Therefore, they are well-suited for modeling the intricate relationships between mechanisms of change and outcomes in psychotherapy studies, which are typically beyond experimental control. However, their complexity, coupled with the fact that detailed explanations are often embedded in dense statistical or econometric texts, poses challenges. This paper provides a background on cross-lagged panel models and delves deeper into explaining the issues of 1) dynamic panel bias, 2) long-run effects, and 3) testing whether different treatments work by different mechanisms. Using data from a psychotherapy study on treatment of adolescent depression, I demonstrate how these issues manifest in real data. In conclusion, I recommend using structural equation modeling to circumvent dynamic panel bias, reporting long-run effects to reveal the long-term impact of sustained therapeutic work on mechanisms of change, and carefully considering whether mediation, moderation, or a combination of both, best describes differential effects of mechanisms between treatments.

Therapists' in-session feelings in psychotherapy can be seen as indications of the development of the therapeutic relationship and the therapeutic process. To manage them appropriately, it is important to know to what extent they may be influenced by patients' pretreatment characteristics. This study aims to improve the understanding of therapists' emotional reactions in the psychotherapeutic setting by investigating if patients' pretreatment mentalization ability and attachment style predicted therapist in-session feelings. In a sample of 87 therapy dyads treated with interpersonal psychotherapy and cognitive behavioral therapy for depression, patient attachment was measured using self-reported Experiences in Close Relationships (ECR) and mentalization using Reflective Functioning (RF). ECR and RF were hypothesized to predict therapist feelings measured by the Feeling Word Checklist-24 at different treatment phases over the full course of treatment. Treatment method, patient age, gender, and pretreatment depression were evaluated as potential confounders. Multilevel modeling was used to analyze the data. Lower RF in patients predicted more negative therapist feelings in the mid- to late-treatment phases and less positive feelings in the late-treatment phase. Self-reported attachment anxiety or avoidance did not predict therapist feelings. Findings indicate that patients' ability to mentalize is important to consider when conducting psychotherapy, as it can influence therapists' feelings in the therapeutic process. Limitations of the present study's approach are discussed, and directions for future research are considered. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

OBJECTIVE: The objective was to test the hypothesis that externalizing and internalizing helpfulness beliefs and learning styles at baseline moderate panic severity and overall mental illness as short-term and long-term outcomes of two panic-focused psychotherapies, Panic Control Treatment (PCT) and Panic-Focused Psychodynamic Psychotherapy (PFPP). METHOD: Participants were 108 adults with DSM-IV Panic Disorder with or without Agoraphobia (PD/A) who were randomized to treatment in a trial of PCT and PFPP. Piece-wise/segmented multilevel modeling was used to test three-way interactions (Treatments × Moderator × Time), with participants and therapists as random factors. Outcome variables were clinician-rated panic severity and self-rated mental illness post-treatment and during follow-up. RESULTS: Patients' externalizing (but not internalizing) helpfulness beliefs moderated mental illness outcomes during follow-up (but not during treatment); low levels of Externalization were facilitative for PFPP but not PCT. Internalizing and externalizing helpfulness beliefs and learning style did not moderate clinician-rated panic severity, whether short- or long-term. CONCLUSIONS: These results suggest that helpfulness beliefs and learning style have limited use in assignment to either PCT or PFPP for PD/A. Although further research is needed, low levels of helpfulness beliefs about externalizing coping may play a role in mental illness outcomes for PFPP.
RESUMEN
Objective: The effects of panic-specific psychotherapy on occupational functioning remain under-researched. This study tests whether two brief psychotherapies for Panic Disorder with or without Agoraphobia (PD/A) may generate improvement in work ability. Methods: Adults (N = 221) with a primary diagnosis of PD/A were randomised to wait-list, panic-focused psychodynamic psychotherapy (PFPP), panic control treatment (PCT), or to the choice between the two treatments. Participants completed the Work Ability Inventory (WAI) at baseline, post-treatment, and during 24-month follow-ups. Change in WAI scores were assessed using segmented multilevel linear growth models, and mediation was explored through path analysis. Results: WAI scores changed from the moderate to good range between baseline and post-treatment (SMD = 0.45; 95% CI [0.33, 0.57]) and continued to increase throughout the follow-up (SMD = 0.16; 95% CI [0.03, 0.28]) with no differences between treatments or allocation forms. In PFPP (but not in PCT) pre- to post-treatment change in WAI was mediated by reduction in panic symptoms and WAI predicted employment status and absences. Conclusions: Two brief panic specific psychotherapies, one cognitive behavioural and one psychodynamic, produced short and long-term increases in work ability.

There has been a growing emphasis on dissemination of empirically supported treatments. Dissemination, however, should not be restricted to treatment. It can and, in the spirit of the scientific-practitioner model, should also involve research. Because it focuses on the investigation of clinical routine as it takes place in local settings and because it can involve the collaboration of several stakeholders, practice-oriented research (POR) can be viewed as an optimal research method to be disseminated. POR has the potential of addressing particularly relevant gaps of knowledge and action when implemented in regions of the world that have limited resources for or experiences with empirical research, and/or in clinical settings that are serving clinical populations who are not typically receiving optimal mental care services - specifically, individuals in rural and inner cities that have limited economic and social resources. The establishment and maintenance of POR in such regions and/or settings, however, come with specific obstacles and challenges. Integrating the experiences acquired from research conducted in various continents (Africa, Europe, Latin America, and North America), the goal of this paper is to describe some of these challenges, strategies that have been implemented to address them, as well as new possible directions to facilitate the creation and growth of POR. It also describes how these challenges and ways to deal with them can provide helpful lessons for already existing POR infrastructures.

Intervention studies in psychology often focus on identifying mechanisms that explain change over time. Cross-lagged panel models (CLPMs) are well suited to study mechanisms, but there is a controversy regarding the importance of detrending-defined here as separating longer-term time trends from cross-lagged effects-when modeling these change processes. The aim of this study was to present and test the arguments for and against detrending CLPMs in the presence of an intervention effect. We conducted Monte Carlo simulations to examine the impact of trends on estimates of cross-lagged effects from several longitudinal structural equation models. Our simulations suggested that ignoring time trends led to biased estimates of auto- and cross-lagged effects in some conditions, while detrending did not introduce bias in any of the models. We used real data from an intervention study to illustrate how detrending may affect results. This example showed that models that separated trends from cross-lagged effects fit better to the data and showed nonsignificant effect of the mechanism on outcome, while models that ignored trends showed significant effects. We conclude that ignoring trends increases the risk of bias in estimates of auto- and cross-lagged parameters and may lead to spurious findings. Researchers can test for the presence of trends by comparing model fit of models that take into account individual differences in trends (e.g., autoregressive latent trajectory model, the latent curve model with structured residuals, or the general cross-lagged model).

RESUMEN
OBJECTIVE: Research has given limited attention to the distinction between patients from rural and urban areas, especially concerning the frequent overlap between rural living and low socio-economic status (SES). To shed more light on this, we explored the differential treatment processes between patients from rural and urban areas. METHOD: Seven hundred and fourteen patients recruited from a university counseling center in China filled out the questionnaires for Outcome Expectation (OE), Session Alliance Inventory (SAI) and Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) each session. Data was analyzed using the disaggregated cross-lagged panel model and the asymmetric fixed-effect model. RESULTS: The findings indicated a reciprocal within-patient relation between OE and SAI for the whole sample. SAI mediated the effect of OE on next-session CORE-OM for patients from rural areas, with a significantly greater indirect effect than for patients from the urban areas. Asymmetric effects were found for OE among patients from urban areas, for whom drops in OE predicted worse next-session CORE-OM more strongly than improvements in OE predicted improved CORE-OM. CONCLUSION: This study provided preliminary evidence for differential OE-alliance-outcome predictions between patients with different SES and affirmed a reciprocal OE-alliance relation in a Chinese sample during the transition period of college.
RESUMEN
BACKGROUND: Existing literature suggests that patients' experiences of emotions, especially negative emotions, predict outcomes in psychotherapies for major depressive disorder. However, the specific mechanisms underlying this effect remain unclear. Based on studies pointing to the role of oxytocin (OT) in attachment relationships, we proposed and tested a mediation model where the therapists' hormonal responses, as represented by increases in their OT levels, mediates the association between negative emotions and symptomatic change. METHOD: OT saliva samples (pre- and post-session, N = 435) were collected on a fixed schedule over 16 sessions from the therapists of 62 patients receiving psychotherapy for major depression. The Hamilton Rating Scale for Depression was administered to the patients before the sessions, and the patients reported their in-session emotions after the sessions. RESULTS: The findings support the proposed within-person mediation model: (a) higher levels of negative emotions in patients predicted greater increases in therapist OT levels pre- to post-session throughout treatment; (b) greater OT levels in therapists, in turn, predicted reduction in patients' depressive symptoms on the subsequent assessment; and (c) the therapists' OT levels significantly mediated the association between patients' negative emotions and reduction in their depressive symptoms. LIMITATIONS: This design precluded establishing a time sequence between patients' negative emotions and therapists' OT; thus, causality could not be inferred. CONCLUSION: These findings point to a possible biological mechanism underlying the effects of patients' experiences of negative emotions on treatment outcomes. The findings suggest that therapists' OT responses could potentially serve as a biomarker of an effective therapeutic processes.

INTRODUCTION: The aim of the Common factors, Responsiveness and Outcome in Psychotherapy (CROP) study is to identify client and psychologist characteristics and therapeutic processes associated with the outcome of psychotherapy delivered by psychologists employed in the Danish primary sector or fully self-employed. The study addresses two main questions. First, how are specific characteristics of clients and psychologists related to the outcome of therapy and do these characteristics moderate the outcome of different psychotherapeutic approaches? Second, to what extent do therapists adapt their approach to client characteristics and preferences and how does such responsiveness impact the process and outcome of therapy? METHODS AND ANALYSIS: The study is a naturalistic prospective cohort study carried out in collaboration with psychologists in private practice in Denmark. Self-reported data are collected from the participating psychologists and their participating clients before, during (weekly and postsession) and after psychotherapy (at end of treatment and 3 months follow-up). The estimated target sample size is 573 clients. The data are analysed using multilevel modelling and structural equation modelling approaches to capture predictors and moderators of the effect and rate of change in psychotherapy as well as session-to-session changes during the therapy process. ETHICS AND DISSEMINATION: The study has been approved by the IRB at the Department of Psychology, University of Copenhagen (IRB number: IP-IRB/01082018) and the Danish Data Protection Agency. All study data are fully anonymised and all clients have given informed consent to participation in the study. The study findings will be presented in articles in international, peer-reviewed journals as well as to psychotherapy practitioners and other professionals across Denmark.

OBJECTIVE: Therapeutic alliance is one of the most stable predictors of outcome in psychotherapy, regardless of theoretical orientation. The alliance-outcome relationship in internet-based treatments has been investigated with mixed results. There is preliminary evidence that emotion regulation can work as a mediator for the alliance-outcome relationship. The present study aimed to investigate whether alliance predicted outcome session by session in two internet-based treatments for adolescent depression, and whether this relationship was mediated by emotion regulation. METHOD: Two hundred and seventy-two participants aged 15-19 years and diagnosed with depression were randomized to 10 weeks of internet-based psychodynamic or cognitive behavioral treatment. Both therapists and patients rated the alliance weekly. Patients also rated depressive symptoms and emotion regulation weekly. Analyses were made using cross-lagged panel modeling. RESULTS: Alliance, as rated by both therapist and patient, predicted depression scores the following week. Emotion regulation rated by the patient also predicted depression scores the following week. Furthermore, alliance scores predicted emotion regulation scores the following week, which in turn predicted depression scores the week after, supporting the hypothesis that alliance influences outcome partly through emotion regulation. There were no group differences in any of these relationships. CONCLUSION: Alliance seems to play an important role in internet-based treatments, partly through emotion regulation. Clinicians working with text-based treatments should pay attention to the working alliance. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

BACKGROUND: Patients with Major Depressive Disorder (MDD) have been found to have restricted capacity for mentalization, and it is possible that this constitutes a vulnerability factor for developing depression. Due to its focus on linking depressive symptomatology to emotions and interpersonal relations, it was hypothesized that Interpersonal Psychotherapy (IPT) would improve mentalization more than Cognitive Behavioral Therapy (CBT). METHODS: In a randomized controlled trial of 90 patients undergoing IPT and CBT for MDD, Reflective Functioning (RF) was rated from Adult Attachment and from Depression-Specific Reflective Functioning (DSRF) Interviews before and after therapy. Treatment outcome was assessed using the Beck Depression Inventory-II. RESULTS: The interaction between time and treatment approach was statistically significant, with RF improving significantly more in IPT than in CBT. Change in RF was not correlated with change in depression. The difference in DSRF ratings before and after therapy was not statistically significant for any of the treatments. CONCLUSIONS: IPT may improve mentalization more than CBT. However, although RF increased significantly in IPT, the mean level was still low after therapy. A limitation of the study is the large amount of post-treatment missing data. More research is needed to understand the potential role of mentalization in symptom reduction.

OBJECTIVE: The objective of this study was to analyze the effect of adherence to both specific technique factors and facilitative condition variables (e.g., therapists' involvement, understanding and support) in Cognitive Behavior Therapy (CBT) and Interpersonal Psychotherapy (IPT). In addition, we were interested in whether the effect of therapist adherence would depend on the level of the working alliance. METHOD: Three sessions each from 74 patients diagnosed with Major Depressive Disorder who were randomized to 14 sessions of IPT or CBT were rated for adherence using a modified version of The Collaborative Study Psychotherapy Rating Scale-6 (CSPRS-6). Data was analyzed using Multilevel Modeling. RESULTS: No effects of adherence to specific factors on outcome were found in neither CBT nor IPT. Facilitative conditions were associated with better outcome in CBT but not in IPT, even after adjustment for the quality of the working alliance. No interaction effects were found. CONCLUSIONS: Our findings highlight the importance of relational factors in CBT, but do not support the need for specific adherence to any of the two treatments. Possible explanations of the findings and directions for future research are discussed.Trial registration: ClinicalTrials.gov identifier: NCT01851915.

Causal inference in psychological research is typically hampered by unobserved confounding. A copula-based method can be used to statistically control for this problem without the need for instruments or covariates, given relatively lenient distributional assumptions on independent variables and error terms. The current study aims to: (a) provide a user-friendly introduction to the copula method for psychology researchers, and (b) examine the degree of non-normality in the independent variables required for satisfactory performance. A Monte Carlo simulation study was used to assess the behavior of the copula method under various combinations of conditions (sample size, skewness of independent variables, effect size, and magnitude of confounding). In addition, an applied example from research on the effects of parental rearing on adult personality and life satisfaction was used to illustrate the method. Simulations revealed that the copula method performed better at higher levels of skewness in the independent variables, and that the impacts of lower skewness can be offset to some extent by larger sample size. When skewness and/or sample size is too small, the copula method is biased toward the uncorrected model. In the applied example, parental rejection/punishment predicted less adaptive personality and life satisfaction, with no evidence of confounding. For parental control/overprotection, there was evidence that confounding attenuated the estimated relationship with personality/life satisfaction. Copula adjustment is a promising method for handling unobserved confounding. The discussion focuses on how to proceed when assumptions are not quite met, and outlines potential avenues for future research. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

OBJECTIVE: The aim of this study is to examine the amount of the total variance of the subjective well-being (SWB) of psychotherapists from 12 European countries explained by between-country vs. between-person differences regarding its cognitive (life satisfaction) and affective components (positive affect [PA] and negative affect [NA]). Second, we explored a link between the SWB and their personal (self-efficacy) and social resources (social support) after controlling for sociodemographics, work characteristics, and COVID-19-related distress. METHODS: In total, 2915 psychotherapists from 12 countries (Austria, Bulgaria, Cyprus, Finland, Great Britain, Serbia, Spain, Norway, Poland, Romania, Sweden, and Switzerland) participated in this study. The participants completed the Satisfaction with Life Scale (SWLS), the International Positive and Negative Affect Schedule Short Form (I-PANAS-SF), the General Self-Efficacy Scale, and the Multidimensional Scale of Perceived Social Support. RESULTS: Cognitive well-being (CWB; satisfaction with life) was a more country-dependent component of SWB than affective well-being (AWB). Consequently, at the individual level, significant correlates were found only for AWB but not for CWB. Higher AWB was linked to being female, older age, higher weekly workload, and lower COVID-19-related distress. Self-efficacy and social support explained AWB only, including their main effects and the moderating effect of self-efficacy. CONCLUSIONS: The results highlight more individual characteristics of AWB compared to CWB, with a more critical role of low self-efficacy for the link between social support and PA rather than NA. This finding suggests the need for greater self-care among psychotherapists regarding their AWB and the more complex conditions underlying their CWB.

The aim of this study was to examine cross-cultural differences, as operationalized by Schwartz's refined theory of basic values, in burnout levels among psychotherapists from 12 European countries during the coronavirus disease (COVID-19) pandemic. We focused on the multilevel approach to investigate if individual- and country-aggregated level values could explain differences in burnout intensity after controlling for sociodemographic, work-related characteristics and COVID-19-related distress among participants. 2915 psychotherapists from 12 countries (Austria, Bulgaria, Cyprus, Finland, Great Britain, Serbia, Spain, Norway, Poland, Romania, Sweden, and Switzerland) participated in this study. The participants completed the Maslach Burnout Inventory-Human Service Survey, the revised version of the Portrait Values Questionnaire, and a survey questionnaire on sociodemographic, work-related factors and the COVID-19 related distress. In general, the lowest mean level of burnout was noted for Romania, whereas the highest mean burnout intensity was reported for Cyprus. Multilevel analysis revealed that burnout at the individual level was negatively related to self-transcendence and openness-to-change but positively related to self-enhancement and conservation values. However, no significant effects on any values were observed at the country level. Male sex, younger age, being single, and reporting higher COVID-19-related distress were significant burnout correlates. Burnout among psychotherapists may be a transcultural phenomenon, where individual differences among psychotherapists are likely to be more important than differences between the countries of their practice. This finding enriches the discussion on training in psychotherapy in an international context and draws attention to the neglected issue of mental health among psychotherapists in the context of their professional functioning.

BACKGROUND: Adolescent major depressive disorder (MDD) is highly prevalent and associated with lifelong adversity. Evidence-based treatments exist, but accessible treatment alternatives are needed. We aimed to compare internet-based psychodynamic therapy (IPDT) with an established evidence-based treatment (internet-based cognitive behavioural therapy [ICBT]) for the treatment of adolescents with depression. METHODS: In this randomised, clinical trial, we tested whether IPDT was non-inferior to ICBT in the treatment of adolescent MDD. Eligible participants were 15-19 years old, presenting with a primary diagnosis of MDD according to DSM-5. Participants were recruited nationwide in Sweden through advertisements on social media, as well as contacts with junior and senior high schools, youth associations, social workers, and health-care providers. Adolescents who scored 9 or higher on the Quick Inventory of Depressive Symptomatology for Adolescents (QIDS-A17-SR) in an initial online screening were contacted by telephone for a diagnostic assessment using the Mini International Neuropsychiatric Interview. Participants were randomly assigned to ICBT or IPDT. Both interventions comprised eight self-help modules delivered over 10 weeks on a secure online platform. The primary outcome was change in depression severity measured weekly by the QIDS-A17-SR. Primary analyses were based on an intention-to-treat sample including all participants randomly assigned. A non-inferiority margin of Cohen's d=0·30 was predefined. The study is registered at ISRCTN, ISRCTN12552584. FINDINGS: Between Aug 19, 2019, and Oct 7, 2020, 996 young people completed screening; 516 (52%) were contacted for a diagnostic interview. 272 participants were eligible and randomly assigned to ICBT (n=136) or IPDT (n=136). In the ICBT group, 51 (38%) of 136 participants were classified as remitted, and 54 (40%) of 136 participants were classified as remitted in the IPDT group. Within-group effects were large (ICBT: within-group d=1·75, 95% CI 1·49 to 2·01; IPDT: within-group d=1·93, 1·67 to 2·20; both p<0·0001). No statistically significant treatment difference was found in the intention-to-treat analysis. Non-inferiority for IPDT was shown for the estimated change in depression during treatment (d=-0·18, 90% CI -0·49 to 0·13; p=0·34). All secondary outcomes showed non-significant between-group differences. INTERPRETATION: IPDT was non-inferior to ICBT in terms of change in depression for the treatment of adolescents with MDD. This finding increases the range of accessible and effective treatment alternatives for adolescents with depression. FUNDING: Kavli trust.

OBJECTIVE: Several studies have shown that the quality of the working alliance predicts symptomatic improvement session-by-session, including in cognitive-behavioral therapy (CBT). We wanted to explore what characterizes CBT sessions with high and low alliances further using qualitative analysis. METHOD: Ten CBT-sessions were selected from eight patients' therapies in a larger research project on psychotherapy for patients with major depression. Five sessions were chosen from high- and five from low-alliance sessions, based on therapist- and patient-reported Working Alliance Inventory scores. Transcripts of these sessions were analyzed using thematic analysis. RESULTS: The analysis yielded four themes, each structured into two sub-themes: Therapist style, Person in focus, Content focus, and Therapeutic direction. In contrast to low-alliance sessions, high-alliance sessions were characterized by a more exploring as opposed to expert therapist style; a focus on the patient's thoughts, feelings, and behavior, rather than a diffuse focus or a focus on other people's actions/external events; and a sense of moving forward rather than stagnation. CONCLUSION: Our qualitative analysis showed theoretically and clinically meaningful processes in CBT sessions of high- vs low working alliance. This method is a useful complement to quantitative within-patient analyses, to expand on the meaning of quantitative findings.

OBJECTIVE: Modeling cross-lagged effects in psychotherapy mechanisms of change studies is complex and requires careful attention to model selection and interpretation. However, there is a lack of field-specific guidelines. We aimed to (a) describe the estimation and interpretation of cross lagged effects using multilevel models (MLM) and random-intercept cross lagged panel model (RI-CLPM); (b) compare these models' performance and risk of bias using simulations and an applied research example to formulate recommendations for practice. METHOD: Part 1 is a tutorial focused on introducing/describing dynamic effects in the form of autoregression and bidirectionality. In Part 2, we compare the estimation of cross-lagged effects in RI-CLPM, which takes dynamic effects into account, with three commonly used MLMs that cannot accommodate dynamics. In Part 3, we describe a Monte Carlo simulation study testing model performance of RI-CLPM and MLM under realistic conditions for psychotherapy mechanisms of change studies. RESULTS: Our findings suggested that all three MLMs resulted in severely biased estimates of cross-lagged effects when dynamic effects were present in the data, with some experimental conditions generating statistically significant estimates in the wrong direction. MLMs performed comparably well only in conditions which are conceptually unrealistic for psychotherapy mechanisms of change research (i.e., no inertia in variables and no bidirectional effects). DISCUSSION: Based on conceptual fit and our simulation results, we strongly recommend using fully dynamic structural equation modeling models, such as the RI-CLPM, rather than static, unidirectional regression models (e.g., MLM) to study cross-lagged effects in mechanisms of change research.
