Background: Randomized trials of the effects of psychological therapies seek internal validity via homogeneous samples and standardized treatment protocols. In contrast, practice-based studies aim for clinical realism and external validity via heterogeneous samples of clients treated under routine practice conditions. We compared indices of treatment effects in these two types of studies.Method: Using published transformation formulas, the Beck Depression Inventory (BDI) scores from five randomized trials of depression (N = 477 clients) were transformed into Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) scores and compared with CORE-OM data collected in four practice-based studies (N = 4,196 clients). Conversely, the practice-based studies' CORE-OM scores were transformed into BDI scores and compared with randomized trial data.Results: Randomized trials showed a modest advantage over practice-based studies in amount of pre-post improvement. This difference was compressed or exaggerated depending on the direction of the transformation but averaged about 12%. There was a similarly sized advantage to randomized trials in rates of reliable and clinically significant improvement (RCSI). The largest difference was yielded by comparisons of effect sizes which suggested an advantage more than twice as large, reflecting narrower pre-treatment distributions in the randomized trials.Conclusions: Outcomes of completed treatments for depression in randomized trials appeared to be modestly greater than those in routine care settings. The size of the difference may be distorted depending on the method for calculating degree of change. Transforming BDI scores into CORE-OM scores and vice versa may be a preferable alternative to effect sizes for comparisons of studies using these measures. [ABSTRACT FROM AUTHOR]

BACKGROUND: Psychotherapy's equivalence paradox is that treatments tend to have equivalently positive outcomes despite non-equivalent theories and techniques. We replicated an earlier comparison of treatment approaches in a sample four times larger and restricted to primary-care mental health.MethodPatients (n=5613) who received cognitive-behavioural therapy (CBT), person-centred therapy (PCT) or psychodynamic therapy (PDT) at one of 32 NHS primary-care services during a 3-year period (2002-2005) completed the Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM) at the beginning and end of treatment. Therapists indicated which approaches were used on an End of Therapy form. We compared outcomes of groups treated with CBT (n=1045), PCT (n=1709), or PDT (n=261) only or with one of these plus one additional approach (e.g. integrative, supportive, art), designated CBT+1 (n=1035), PCT+1 (n=1033), or PDT+1 (n=530), respectively. RESULTS: All six groups began treatment with equivalent CORE-OM scores, and all averaged marked improvement (overall pre/post effect size=1.39). Neither treatment approach nor degree of purity ('only' v. '+1') had a statistically significant effect. Distributions of change scores were all similar. CONCLUSIONS: Replicating the earlier results, the theoretically different approaches tended to have equivalent outcomes. Caution is warranted because of limited treatment specification, non-random assignment, incomplete data, and other issues. Insofar as these routine treatments appear effective for patients who complete them, those who fail to complete (or to begin) treatment deserve attention by researchers and policymakers.

BACKGROUND: It is important to know the stability of standard outcome measures prior to therapy over differing periods of time that map onto the realities of waiting times in routine service settings. METHOD: We studied 1,684 clients who completed one or both the targeted measures Clinical Outcomes in Routine Evaluation-Outcome Measures (CORE-OM) and Beck Depression Inventory-I (BDI-I) two times, at intervals of up to 12 months, prior to beginning psychotherapy. We also selected an additional 1,623 clients who completed the CORE-OM (N=1,623), BDI-I (N=980) or both at referral, but had no records of further contact with the service. RESULTS: There was little change in the mean CORE-OM or BDI-I scores between referral and clinical assessment. The test-retest correlations showed substantial stability on both measures, declining only moderately at the longer intervals studied. CONCLUSION: The high test-retest correlations for periods of up to 6 months suggest that psychological disturbance was both reliably measured by the CORE-OM and the BDI-I, and reasonably stable among clients waiting to be assessed. Implications for routine practice are discussed. [ABSTRACT FROM AUTHOR]

OBJECTIVES: The Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM) and the Beck Depression Inventory (BDI) are routinely used to assess emotional problems. It would be helpful to be able to compare scores when only one of the measures is available. We investigated the relationship between the measures and produced translation tables. METHODS: Level of agreement between CORE-OM and BDI-I was assessed for 2,234 clients who had completed both measures at referral for routine secondary care. Tables for predicting between the measures were constructed using several methods, including non-linear regression and non-parametric smoothing. Results were cross-validated on a separate sample of 326 clients. RESULTS: High correlations between the measures were obtained (r=.862 for female clients; r=.855 for male clients). Accuracy in predicting caseness is higher than predicting depression levels. CONCLUSIONS: CORE-OM and BDI can be compared in routine clinical settings with acceptable accuracy.

BACKGROUND: Psychotherapy's equivalence paradox is that treatments have equivalently positive outcomes despite non-equivalent theories and techniques. We compared the outcomes of contrasting approaches practised in routine care. METHOD: Patients (n = 1309) who received cognitive-behavioural therapy (CBT), person-centred therapy (PCT) and psychodynamic therapy (PDT) at one of 58 National Health Service (NHS) primary and secondary care sites in the UK during a 3-year period completed the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) at the beginning and end of their treatment. Therapists indicated which treatment approaches were used on an End of Therapy form. We compared outcomes of six groups: three treated with CBT, PCT or PDT only, and three treated with one of these plus one additional approach (e.g. integrative, supportive, art), designated CBT+1, PCT+1 or PDT+1 respectively. RESULTS: All six groups averaged marked improvement (pre-post effect size = 1.36). Treatment approach and degree of purity ('only' vs. '+1') each accounted for statistically significant but comparatively tiny proportions of the variance in CORE-OM scores (respectively 1% and 0.5% as much as pre-post change). Distributions of change scores were largely overlapping. CONCLUSIONS: Results for these three treatment approaches as practised routinely across a range of NHS settings were generally consistent with previous findings that theoretically different approaches tend to have equivalent outcomes. Caution is warranted because of limited treatment specification, non-random assignment, lack of a control group, missing data and other issues. [ABSTRACT FROM AUTHOR]

This study followed up one by Stiles et al. (2003), which identified sudden gains -- large reductions from one session to the next on a short form of clinical outcomes in routine evaluation outcome measure (CORE-SF) -- by some clients in routine clinical practice. We interviewed the therapists who had treated sudden gain and non-sudden gain clients. Results showed that therapists could retrospectively identify which clients had or had not experienced sudden CORE-SF gains at substantially better than chance rates, although they identified only about half of the clients who had experienced such gains.

According to the assimilation model, personality may be considered as a community of internal voices representing traces of previous experiences. This study addressed the hypothesis that a person's internal voices sound different from each other. First, following an intensive qualitative procedure, four clinically sophisticated raters identified six internal voices in a 45-minute interview with Mary, a graduate student in psychology. They characterized the voices by (a) distinctive names, (b) descriptions of vocal and personality characteristics, and (c) sets of excerpted passages. Next, using the voice names and descriptions, additional raters independently sorted the passages into groups. Sortings based on transcript plus audio agreed with the sophisticated raters on 68.9% of the passages, as compared with 37.2% for sortings based on transcript only, while chance agreement expected for both was 16.7%. These findings support a literal view of internal multiplicity, consistent with a modular organization of experiential information within personality. [ABSTRACT FROM AUTHOR]

The main outcome and process findings from the Second Sheffield Psychotherapy Project (SPP2) support the equivalence paradox: the overall outcomes of cognitive-behavioural (CB) and psychodynamic-interpersonal (P1) therapy were roughly the same, but the content of the two treatments were different. However, when we compared specific groups of clients or specific problems CB therapy showed an outcome advantage to PI therapy. Subsequent analyses of the data suggested that two factors accounted for these differences in treatment outcome and processes: the extent to which clients had assimilated their problems at the beginning of therapy and therapists' responsiveness to clients' interpersonal style. The implications of the SPP2 findings for clinical practice are discussed. [ABSTRACT FROM AUTHOR]

Objective: How are collaborative interactions associated with clients' progress in therapy? This study addressed this question, by assessing the quality of therapeutic collaboration and comparing it passage by passage with the clients' assimilation of problematic experiences in two cases of major depression treated with Cognitive Behavioral Therapy, one recovered and one improved-but-not-recovered., Method: We used the Therapeutic Collaboration Coding System to code collaborative work and the Assimilation of Problematic Experiences Scale (APES) to rate clients' progress. In both cases, for the distribution of specific collaborative therapeutic exchanges, we tested for the difference of empirical means between lower and higher APES levels., Results: Both cases progress in APES, but in contrast with Annie (Improved-but-not-recovered), Kate (Recovered) achieved higher levels of change in last sessions. In addition, we found significant differences in the types of collaborative therapeutic exchanges associated with lower and higher APES levels., Conclusion: Ambivalent therapeutic exchanges distinguished the recovered case from the not recovered case highlighting a source of difficulties in facilitating therapeutic change in CBT. In addition, observations in these cases supported the theoretical suggestion that supporting interventions would be better accepted at lower APES levels, whereas challenging interventions would be better accepted at higher APES levels.

The assimilation model suggests that therapeutic change occurs through a gradual assimilation of problematic experiences. Previous case studies have suggested that both good- and poor-outcome cases exhibit a fluctuating pattern of assimilation progress, characterized by advances and setbacks. Our study examined more closely how this fluctuating pattern is related to symptom change across therapy. We analyzed the longitudinal relations among assimilation ratings, instability (fluctuation) in assimilation ratings, and clinical symptom intensity in two contrasting cases of emotion-focused therapy for depression, one good and one poor outcome. We used the assimilation of problematic experiences scales (APES) to measure assimilation and the outcome- questionnaire (OQ-10) to measure clinical symptom intensity. To assess assimilation instability, we used a fluctuation measure that calculated the amplitude and the frequency of changes in assimilation levels. The results showed that in the good-outcome case, assimilation levels and instability tended to increase and symptom intensity tended to decrease, particularly in the final phase of treatment. In the poor-outcome case, assimilation levels and instability did not change much across sessions.

Objective : This theory-building case study investigated setbacks in assimilation, seeking to replicate and elaborate previous work, in which most setbacks were one of two types, balance strategy (BS) or exceeding the therapeutic zone of proximal development (TZPD). Method : We studied the case of Alicia, a 26 year-old woman, treated successfully for depression. Her main problematic experiences were rated with the Assimilation of Problematic Experiences Scale (APES), and 267 setbacks were identified. We classified the setbacks and examined them quantitatively and qualitatively. Results : Alicia showed the usual irregular progress of assimilation, with generally increasing APES ratings, consistent with the improvements in outcome measures. Almost all setbacks could be distinguished as BS or TZPD. Replicating a previously observed pattern, BS setback passages tended to be at or above APES stage 3, whereas TZPD setback passages tended to be below APES stage 3. BS and TZPD setbacks also drew qualitatively different characterizations. Conclusion : Results represented a conceptual replication of previous work, explainable using the same theoretical tenets. As an integral part of therapeutic work, setbacks do not impede progress in therapy. BS and TZPD setbacks reflect different processes and have different implications for how therapist and client are working together.

Psychological intervention outcomes depend in part on the therapist who provides the intervention (a therapist effect). However, recent reviews suggest that therapist effects may vary as a function of the context in which care is provided and therefore should not be generalized beyond that context. This study statistically analysed therapist effect differences between care sectors delivering psychological interventions. The sample comprised routine clinical data from 26,814 patients (69% female; mean age 38) and 466 therapists in five care sectors: primary care, secondary care, university, voluntary, and workplace. Therapist effects were analysed using multilevel models and Markov chain Monte Carlo credible intervals. The therapist effect was significantly larger in primary care (8.4%) than in any other sector (1.1%-2.3%) except secondary care (4.1%), after controlling for explanatory baseline and process variables as well as accounting for differences between clinics. There were no other significant differences detected between care sectors. These findings support the hypothesis that differences in effectiveness between therapists vary depending on the context in which psychological treatment is provided. Differences in relative therapist impact can vary by a factor of 4-8 across treatment sectors. This should be considered in the application of research evidence, treatment planning, and the design and delivery of psychological care provision., (© 2020 The Authors. Clinical Psychology & Psychotherapy published by John Wiley & Sons Ltd.)

Objective: The study aimed to (a) investigate the effect of treatment location on clinical outcomes for patients receiving psychological therapy (a clinic effect, akin to the concept of a therapist effect) and (b) assess the impact of explanatory individual and aggregate demographic and process variables on the clinic and therapist effects., Method: The sample comprised 26,888 patients, seen by 462 therapists, across 30 clinics. Mean patient age was 38 years (69% female, 90% White, 92% planned ending). The dependent variable was patients' posttherapy score on the Clinical Outcomes in Routine Evaluation-Outcome Measure. An incremental 3-level multilevel model was constructed. Markov Chain Monte Carlo estimation created 95% probability intervals for the clinic and therapist effects., Results: A 3-level model with no explanatory variables detected a clinic effect of 8.2%, significantly larger than the therapist effect of 3.2%. Adding explanatory variables significantly reduced the clinic effect to 1.9% but did not significantly alter the therapist effect (3.4%). Patient-level symptom severity and employment status, and clinic-level percentage of White patients and health care sector, explained the most clinic outcome variance and overall outcome variance., Conclusions: Substantial variability in clinical outcomes was found between clinics providing psychological therapy. Socioeconomic mix of patients explained significant proportions of variability at the clinic level but not the therapist level. Clinical implications include the need to go beyond the therapist-patient interaction to deliver effective psychological therapy. Future research is also needed to identify the mechanisms by which clinic and/or area-level factors impact on clinical outcomes. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Dynamic systems theory suggests that instability can be a key element in the promotion of human change processes. Several studies have confirmed an association between unstable patterns and successful psychotherapeutic outcome. Somewhat similarly, the assimilation model of psychotherapeutic change argues that clinical change occurs through the integration of problematic experiences that initially threaten the stability of the self. This study examined how instability in assimilation levels was related to assimilation progress and change in symptom intensity, within and across sessions, in a good-outcome case of Emotion Focused Therapy. We used the assimilation of problematic experiences scales (APES) to measure assimilation and the outcome-questionnaire (OQ-10) to measure clinical symptom intensity. To assess assimilation instability, we used a fluctuation measure that calculated the amplitude and the frequency of changes in assimilation levels. To analyze the structural relationships between variables we used a dynamic factor model. The results showed that APES level and APES fluctuation tended to increase across treatment, while OQ-10 scores tended to decrease. However, contrary to expectations, the dynamic factor model showed no significant associations between APES fluctuation and OQ-10 scores either within sessions or between adjacent sessions.

Objective: Some studies have suggested that a decrease in immersion (egocentric perspective on personal experiences) and an increase in distancing (observer perspective on personal experiences) are associated with the resolution of clinical problems and positive outcome in psychotherapy for depression. To help clarify how this change in perspectives relates to clinical change, the present study compared changes in immersion and distancing across therapy with progress in one client's assimilation of her problematic experiences., Method: We analyzed all passages referring to the central problematic experience in a good-outcome case of emotion-focused therapy for depression using the Measure of Immersion and Distancing Speech and the Assimilation of Problematic Experiences Scale., Results: Results showed that immersion and distancing were associated with different stages of assimilation. Immersion was associated with stages of emerging awareness and clarification of the problem and in the application of new understandings to daily life. Distancing was associated with problem-solving and attaining insight., Conclusion: The decrease of immersion and increase of distancing associated with therapeutic improvement should not be taken as a recommendation to avoid immersion and encourage distancing. Immersion and distancing may work as coordinated aspects of the processes of psychotherapeutic change.

The assimilation model describes therapeutic change as an integration of experiences that had previously been problematic, distressing, avoided, or warded off. This study assessed whether assimilation was associated with treatment outcome in a sample of psychotherapeutic treatments for depression. Further, it assessed the direction of the association-whether increasing assimilation predicted decreases in symptom intensity or decreasing symptom intensity predicted increases in assimilation., Method: Participants were 22 clients with mild to moderate depression drawn from a clinical trial comparing cognitive behavioral therapy with emotion-focused therapy. The direction of prediction between assimilation progress and changes in self-reported symptom intensity was assessed., Results: The assimilation progress was shown to be a better predictor of decreases in symptom intensity than the reverse., Conclusion: The results supported the assimilation model's suggestion that assimilation progress promotes decreases in symptom intensity in the treatment of clients with major depressive disorder., (Copyright © 2017 The Authors.

The assimilation model describes the change process in psychotherapy. In this study we analyzed the relation of assimilation with changes in symptom intensity, measured session by session, and changes in emotional valence, measured for each emotional episode, in the case of a 33-year-old woman treated for depression with cognitive-behavioral therapy. Results showed the theoretically expected negative relation between assimilation of the client's main concerns and symptom intensity, and the relation between assimilation levels and emotional valence corresponded closely to the assimilation model's theoretical feelings curve. The results show how emotions work as markers of the client's current assimilation level, which could help the therapist adjust the intervention, moment by moment, to the client's needs.

Aim: We understand ambivalence as a cycle of opposing expressions by two internal voices. The emergence of a suppressed voice produces an innovative moment (IM), challenging the dominant voice, which represents the client's problematic self-narrative. The emergence of the IM is opposed by the dominant voice, leading to a return to the problematic self-narrative. This study analyzed therapist and client responses to each other in episodes of ambivalence., Method: The therapeutic collaboration coding system (TCCS) assesses whether and how the therapeutic dyad is working within the therapeutic zone of proximal development (TZPD) by examining client responses to therapist interventions. We applied the TCCS to episodes in which a good- and a poor-outcome client in narrative therapy expressed ambivalence., Results: In both the good- and poor-outcome cases, the therapist responded to the emergence of ambivalence similarly, balancing challenging and supporting. The good-outcome case responded at the developmental level proposed by the therapist when challenged, while the poor-outcome case lagged behind the level proposed., Discussion: This supports the theoretical explanation that the therapist did not match client's developmental level in the poor-outcome case, working beyond the client's current TZPD and contributing to the maintenance of ambivalence.

This article introduces a Special Section of case studies that focus on therapeutic collaboration and setbacks in the process of assimilation with the aim of contributing to the evolution of the assimilation model of therapeutic change. The first study examined setbacks in two depression cases (a good vs. a poor outcome) treated with emotion-focused therapy. The second article traced how therapist activities and positions toward internal voices were associated with setbacks in a case treated with linguistic therapy of evaluation. The third article studied contributions of therapeutic collaboration for both advances and setbacks in assimilation in two contrasting cases treated with emotion-focused therapy. The fourth and final article analyzed the therapeutic collaboration in episodes of ambivalence in two cases of narrative therapy (one good outcome, one poor outcome) reflecting on the implications for the assimilation model's perspective on the therapeutic relationship. This Introduction concludes by offering some suggestions for theory-building within the assimilation model.

Objective: The Assimilation model argues that therapists should work responsively within the client's therapeutic zone of proximal development (TZPD). This study analyzed the association between the collaborative processes assessed by the Therapeutic Collaboration Coding System (TCCS) and advances in assimilation, as assessed by the Assimilation of Problematic Experiences Scale (APES)., Method: Sessions 1, 4, 8, 12, and 16 of two contrasting cases, Julia and Afonso (pseudonyms), drawn from a clinical trial of 16-sessions emotion-focused therapy (EFT) for depression, were coded according to the APES and the TCCS. Julia met criteria for reliable and clinically significant improvement, whereas Afonso did not., Results: As expected, Julia advanced farther along the APES than did Afonso. Both therapists worked mainly within their client's TZPD. However, Julia's therapist used a balance of supporting and challenging interventions, whereas Afonso's therapist used mainly supporting interventions. Setbacks were common in both cases., Conclusions: This study supports the theoretical expectation that EFT therapists work mainly within their client's TZPD. Therapeutic exchanges involving challenging interventions may foster client change if they occur in an overall climate of safety.

Objective: Research on the assimilation model has suggested that psychological change takes place in a sequence of stages punctuated by setbacks, that is, by transient reversals in the developmental course. This study analyzed such setbacks in one good outcome case and one poor outcome case of Emotion-focused therapy (EFT) for depression., Method: Intensive analyses of five transcribed sessions from each case identified 26 setbacks in the good outcome case and 27 in the poor outcome case. The reason for each setback was classified into one of four categories: balance strategy, exceeding the therapeutic zone of proximal development either induced by the therapist (ZPD-T) or induced by the client (ZPD-C), or spontaneous switches., Results: In the good outcome case the most frequent reasons for setbacks were balance strategy and spontaneous switches, whereas in the poor outcome case the most frequent reason for setbacks was ZPD-T., Conclusions: As in previously studied therapies, setbacks in EFT, usually represent productive work on relatively less advanced strands of the client's major problems. Results point to the importance of the therapist attending to the limits of the client's therapeutic ZPD.

Objective: This study examined the therapist activities immediately preceding assimilation setbacks in the treatment of a good-outcome client treated with linguistic therapy of evaluation (LTE)., Method: Setbacks (N = 105) were defined as decreases of one or more assimilation stages from one passage to the next dealing with the same theme. The therapist activities immediately preceding those setbacks were classified using two kinds of codes: (a) therapist interventions and (b) positions the therapist took toward the client's internal voices., Results: Preceding setbacks to early assimilation stages, where the problem was unformulated, the therapist was more often actively listening, and the setbacks were more often attributable to pushing a theme beyond the client's working zone. Preceding setbacks to later assimilation stages, where the problem was at least formulated, the therapist was more likely to be directing clients to consider alternatives, following the LTE agenda, and setbacks were more often attributable to the client following these directives shifting attention to less assimilated (but nevertheless formulated) aspects of the problem., Conclusions: At least in this case, setbacks followed systematically different therapist activities depending on the problem's stage of assimilation. Possible implications for the assimilation model's account of setbacks and for practice are discussed.

The Assimilation of Problematic Experiences Scale (APES) summarizes a developmental continuum along which psychological problems progress in successful psychotherapy. The therapeutic zone of proximal development (TZPD) is the segment of the APES continuum within which the clients can proceed from their current APES level to the next with the therapist's assistance. It is the therapeutic working zone for a particular problem. As the client makes progress on a problem, its TZPD shifts up the APES. Theoretically, so long as the therapist's interventions remain within the TZPD, the client feels safe enough to work. However, when an intervention aims beyond the upper limit, the client will find it too risky and will reject or avoid the proposal. In this sense, exceeding the TZPD can be considered as a clinical error. This article presents examples of exceeding the TZPD and ways the error can be repaired.

Objective: Our aim was to examine client mood in the initial and final sessions of cognitive-behavioral therapy (CBT) and psychodynamic-interpersonal therapy (PIT) and to determine how client mood is related to therapy outcomes., Methods: Hierarchical linear modeling was applied to data from a clinical trial comparing CBT with PIT. In this trial, client mood was assessed before and after sessions with the Session Evaluation Questionnaire-Positivity Subscale (SEQ-P)., Results: In the initial sessions, CBT clients had higher pre-session and post-session SEQ-P ratings and greater pre-to-post session mood change than did clients in PIT. In the final sessions, these pre, post, and change scores were generally equivalent across CBT and PIT. CBT outcome was predicted by pre- and post-session SEQ-P ratings from both the initial sessions and the final sessions of CBT. However, PIT outcome was predicted by pre- and post-session SEQ-P ratings from the final sessions only. Pre-to-post session mood change was unrelated to outcome in both treatments., Conclusions: These results suggest different change processes are at work in CBT and PIT.

Unlabelled: Randomized controlled trials (RCTs) are currently the dominant methodology for evaluating psychological treatments. They are widely regarded as the gold standard, and in the current climate, it is unlikely that any particular psychotherapy would be considered evidence-based unless it had been subjected to at least one, and usually more, RCTs. Despite the esteem within which they are held, RCTs have serious shortcomings. They are the methodology of choice for answering some questions but are not well suited for answering others. In particular, they seem poorly suited for answering questions related to why therapies work in some situations and not in others and how therapies work in general. Ironically, the questions that RCTs cannot answer are the questions that are of most interest to clinicians and of most benefit to patients. In this paper, we review some of the shortcomings of RCTs and suggest a number of other approaches. With a more nuanced understanding of the strengths and weaknesses of RCTs and a greater awareness of other research strategies, we might begin to develop a more realistic and precise understanding of which treatment options would be most effective for particular clients with different problems and in different circumstances.

This article describes the Clinical Outcomes in Routine Evaluation (CORE) System and reports on its scientific yield and practice impact. First, we describe the suite of CORE measures, including the centerpiece CORE-Outcome Measure (CORE-OM), its short forms, special purpose forms, translations, and psychometric properties, along with the pretreatment CORE Therapy Assessment Form and the CORE End of Therapy Form. Second, we provide an overview of the scientific yield arising from analyses of large CORE data sets collected in routine practice. Third, we describe the use of CORE measures for feedback in practice settings. Finally, we consider future directions for monitoring and feedback in research and practice., ((c) 2015 APA, all rights reserved).)

Background: Previous studies have reported similar recovery and improvement rates regardless of treatment duration among patients receiving National Health Service (NHS) primary care mental health psychological therapy., Aims: To investigate whether this pattern would replicate and extend to other service sectors, including secondary care, university counselling, voluntary sector and workplace counselling., Method: We compared treatment duration with degree of improvement measured by the Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM) for 26 430 adult patients who scored above the clinical cut-off point at the start of treatment, attended 40 or fewer sessions and had planned endings., Results: Mean CORE-OM scores improved substantially (pre-post effect size 1.89); 60% of patients achieved reliable and clinically significant improvement (RCSI). Rates of RCSI and reliable improvement and mean pre- and post-treatment changes were similar at all tested treatment durations. Patients seen in different service sectors showed modest variations around this pattern., Conclusions: Results were consistent with the responsive regulation model, which suggests that in routine care participants tend to end therapy when gains reach a good-enough level., (© The Royal College of Psychiatrists 2015.)

On the occasion of the 25th anniversary of the journal, Psychotherapy research, three former editors first look back at: (i) the controversial persistence of the Dodo verdict (i.e., the observation that all bona fide therapies seem equally effective); (ii) the connection between process and outcome; (iii) the move toward methodological pluralism; and (iv) the politicization of the field around evidence-based practice and treatment guidelines. We then look forward to the next 25 years, suggesting that it would be promising to focus on three areas: (i) systematic theory-building research; (ii) renewed attention to fine-grained study of therapist techniques; and (iii) politically expedient research on the outcomes of marginalized or emerging therapies.

Objectives: This theory-building case study examined the zone of proximal development (ZPD) in psychotherapy within the assimilation model. Theoretically, the ZPD is the segment of the continuum of therapeutic development within which assimilation of problematic experiences can take place. Work within a problem's current ZPD may be manifested as a Winnicottian ability to play, that is, an ability to adopt a flexible reflexive stance to the presenting problem and be involved in joint examination of possible alternatives. Play may be recognized in the client's receptivity to and creative use of the therapist's formulations of the presenting problems., Design and Methods: A case was selected from a comparative clinical trial of two very brief psychotherapies for mild to moderate depression, the Two-Plus-One Project (Barkham, Shapiro, Hardy, & Rees, 1999, J. Consult. Clin. Psychol., 67, 201). Martha, a woman in her late forties, received two sessions of psychodynamic-interpersonal therapy 1 week apart and a follow-up ('plus one') session approximately 3 months later. Dialogical sequence analysis was used to analyse the transcripts of the three sessions., Results: The analysis revealed Martha's problematic action pattern, which remained unchanged throughout the three sessions. Her ability to use and elaborate the therapist's formulations depended on the referential object that the therapist addressed; in particular, she seemed unable to play with the therapist's formulations of her more problematic experiences., Conclusions: The case helped elucidate how the ZPD is content dependent. Winnicott's conception of playing emphasizes the quality of client response as an indicator of this content sensitivity. Differing breadths of major problems' ZPD, manifested as differing abilities to play with therapists' formulations may explain why some clients improve in psychotherapy while some do not., Practitioner Points: Accessing very problematic content may be very difficult even though the client's ability to mentalize other material appears ordinary. Mildly depressed clients who have developed powerful care-taking coping strategies may not respond to very brief therapeutic interventions. A client's minimal acknowledgements may mislead the therapist into supplementing the client's failing self-reflection rather than addressing the issue that provokes this failure., (© 2014 The British Psychological Society.)

Objectives: We understand ambivalence as a cyclical movement between two opposing parts of the self. The emergence of a novel part produces an innovative moment, challenging the current maladaptive self-narrative. However, the novel part is subsequently attenuated by a return to the maladaptive self-narrative. This study focused on the analysis of the therapeutic collaboration in episodes in which a relatively poor-outcome client in narrative therapy expressed ambivalence., Method: For our analysis we used the Therapeutic Collaboration Coding System, developed to assess whether and how the therapeutic dyad is working within the therapeutic zone of proximal development (TZPD)., Results: Results showed that when the therapist challenged the client after the emergence of ambivalence, the client tended to invalidate (reject or ignore) the therapist's intervention., Conclusions: This suggests that in such ambivalence episodes the therapist did not match the client's developmental level, and by working outside the TZPD unintentionally contributed to the maintaining the client's ambivalence.

The Assimilation of Problematic Experiences Scale (APES) and the Innovative Moments Coding System were applied to transcripts of a successful case of linguistic therapy of evaluation independently by different research groups. Assimilation theory and research suggest that higher APES scores reflect therapeutic gains, with a level of approximately 4.0 separating good from poor outcome cases. The innovative moments (IMs) model suggests that IMs classified as reconceptualization and performing change occur mainly in good outcome cases, whereas action, reflection and protest occur in both good and poor outcome cases. Passages coded as reconceptualization and performing change were rare in this case, but 100% of them were rated at or above APES 4. By contrast, 63% passages coded as action, reflection or protest were rated below APES 4 (Chi-square = 28.62, p < .001). Implications for research are discussed.

Objective: Ambivalence can be understood as a cyclical movement between an emerging narrative novelty-an Innovative Moment (IM)-and a return to a problematically dominant self-narrative. The return implies that the IM, with its potential for change is devalued right after its emergence. Our goal is to test the hypothesis that the probability of the client expressing such form of ambivalence decreases across treatment in good-outcome cases but not in poor-outcome cases., Method: Return-to-the-Problem Markers (RPMs) signaling moments of devaluation of IMs were coded in passages containing IMs in six clients with major depression treated with emotion-focused therapy: three good-outcome cases and three poor-outcome cases., Results: The percentage of IMs with RPMs decreased across therapy in good-outcome cases, whereas it remained unchanged and high in the poor-outcome cases., Conclusions: These results were consistent with the theoretical suggestion that therapeutic failure may be associated with this form of ambivalence.

Background: The quality and strength of the therapeutic collaboration, the core of the alliance, is reliably associated with positive therapy outcomes. The urgent challenge for clinicians and researchers is constructing a conceptual framework to integrate the dialectical work that fosters collaboration, with a model of how clients make progress in therapy., Aim: We propose a conceptual account of how collaboration in therapy becomes therapeutic. In addition, we report on the construction of a coding system - the therapeutic collaboration coding system (TCCS) - designed to analyse and track on a moment-by-moment basis the interaction between therapist and client. Preliminary evidence is presented regarding the coding system's psychometric properties. The TCCS evaluates each speaking turn and assesses whether and how therapists are working within the client's therapeutic zone of proximal development, defined as the space between the client's actual therapeutic developmental level and their potential developmental level that can be reached in collaboration with the therapist., Method: We applied the TCCS to five cases: a good and a poor outcome case of narrative therapy, a good and a poor outcome case of cognitive-behavioural therapy, and a dropout case of narrative therapy., Conclusion: The TCCS offers markers that may help researchers better understand the therapeutic collaboration on a moment-to-moment basis and may help therapists better regulate the relationship., (© 2012 The British Psychological Society.)

The impact of exchanges and client-therapist alliance of online therapy text exchanges were compared to previously published results in face-to-face therapy, and the moderating effects of four participant factors found significant in previously published face-to-face studies were investigated using statistical mixed-effect modeling analytic techniques. Therapists (N=30) and clients (N=30) engaged in online therapy were recruited from private practitioner sites, e-clinics, online counseling centers, and mental-health-related discussion boards. In a naturalistic design, they each visited an online site weekly and completed the standard impact and alliance questionnaires for at least 6 weeks. Results indicated that the impact of exchanges and client-therapist alliance in text therapy was similar to, but in some respects more positive than, previous evaluations of face-to-face therapy. The significance of participant factors previously found to influence impact and alliance in face-to-face therapy (client symptom severity, social support, therapist theoretical orientation, and therapist experience) was not replicated, except that therapists with the more symptomatic clients rated their text exchanges as less smooth and comfortable. Although its small size and naturalistic design impose limitations on sensitivity and generalizability, this study provides some insights into treatment impact and the alliance in online therapy.

In this journal's first article, Strupp (1963) pointed to problems specifying independent and dependent variables as a source of slow progress in psychotherapy outcome research. This commentary agrees, shows how the concept of variable loses its meaning in psychotherapy research because of participants' responsiveness, and notes an alternative research strategy that does not depend on variables.

Abstract This study examined a client's therapeutic progress within one session of an 18-session child neurological assessment. The analysis focused on a parent-psychologist dialogue in one session of the assessment process. Dialogical sequence analysis (DSA; Leiman, 2004, 2012) was used as a micro-analytic method to examine the developing discourse. The analysis traced the mother's developing of a reflective stance toward herself and her problematic ways of interacting with her daughter, who was the client. During the dialogue, the mother began to recognize her own contribution in maintaining the problematic pattern. Her gradual acknowledgment of the child's perspective and her growing sense of the child's otherness were mediated by an observer position (third-person view) toward the problematic pattern, which allowed a flexible exchange between the perspectives of self and the other. The results demonstrate the parallel development of intrapersonal and interpersonal empathy shown previously to characterize the transition from stage 3 (problem statement/clarification) to stage 4 (understanding/insight) in the assimilation of problematic experiences sequence (Brinegar, Salvi, Stiles, & Greenberg, 2006).

The assimilation model suggests progress in psychotherapy follows an eight-stage sequence described by the Assimilation of Problematic Experiences Scale (APES). This study sought to reconcile this developmental stage model with the common but superficially contradictory clinical observation that therapeutic advances alternate with setbacks. Setbacks (n=466) were identified in therapy transcripts of two clients and classified using a preliminary nine-category list of possible alternative reasons for setbacks. Most of the setbacks involved switches among the multiple strands of a problem due to (a) therapists exceeding clients' therapeutic zone of proximal development, (b) therapists guiding clients to shift toward relatively problematic material (balance metaphor), or (c) spontaneous switches. Rather than contradicting the theory, this close examination of setbacks yielded elaborations of it.

Objectives: The question of how effective therapies are in routine practice is crucial. The answer depends on how we define effectiveness. Both the definition of who was treated and the index chosen to represent outcome can affect estimates dramatically., Design: We used data from the Clinical Outcomes in Routine Evaluation (CORE) Primary Care National Practice-Based Evidence database-2005 on the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) from 33,587 patients and examined rates of improvement in psychological therapies in UK National Health Service (NHS) primary care services using various definitions of effectiveness., Methods: We constructed successively more restrictive sub-samples of patients, including practice-based analogues of several types of intent-to-treat (ITT) groups and completer groups. We focussed on patients scoring above clinical cut-off at intake, but we also considered samples that included sub-clinical patients. We assessed two types of recovery rates, improvement rates, mean pre-post change, and pre-post effect sizes for each sub-sample., Results: There was wide variation in the overall effectiveness of treatments as a function of which subset of data was considered and which specific criterion of recovery rate was adopted. Recovery rates and pre-post effect sizes ranged from 19% to 65% and 0.60 to 1.95, respectively., Conclusions: Because estimates of effectiveness could have significant policy implications, clarity on the meanings of the differing constructions is essential., (©2011 The British Psychological Society.)

This article reports the development and psychometric properties of two short forms of the 28-item Agnew Relationship Measure, the ARM-12 and ARM-5. For the ARM-12, results of previous research were used together with conceptual considerations to select three items to represent each of four ARM subscales: Bond, Partnership, Confidence, and Openness. For the ARM-5, item-analytic principles were used to select five items to represent overall alliance. In all three ARMs, client and therapist versions were constructed to contain parallel items. We drew data to assess reliability and validity from three UK trials of brief therapy for depression. Results indicated that the two short ARMs have acceptable psychometric properties and that they converged with each other and with the full ARM.

This study compared participants' speech acts in low-hostile versus moderate-hostile interpersonal episodes in time-limited psychodynamic psychotherapy. Sixty-two cases from the Vanderbilt II psychotherapy project were categorized as low or moderate in interpersonal hostility based on ratings of interpersonal process using Structural Analysis of Social Behavior (Benjamin, 1996). Representative episodes were coded using a taxonomy of speech acts (Stiles, 1992), and speech acts were compared across low- and moderate-hostile episodes. Therapists in moderate-hostility episodes used more interpretations and edifications, and fewer questions and reflections. Patients in moderate-hostility episodes used more disclosures and fewer edifications. Content coding showed that therapist interpretations with a self/intrapsychic self focus were more characteristic of moderate-hostility than low-hostility episodes, whereas the two types of episodes contained similar levels of interpretations focused on the patient's interpersonal relationships and the therapeutic relationship.

Metacognitive theories describe relationships between mental-affective self-states, including the capacity of one self-state to reflect upon another self-state. The assimilation model is a metacognitive approach that understands self-states as made of traces of experiences at different levels of integration. Psychological problems are understood as impaired accessibility of certain self-states to the person's normal awareness. These states are distressing or otherwise subjectively problematic when they emerge. This exploratory study used the assimilation framework to describe mental states in 17 clients who participated in a clinical trial of cognitive-behavioral therapy for depression. Three clinically sophisticated raters examined transcripts of 1h-long psychotherapy session per client to construct qualitative descriptions of self-states and their relationship patterns in these depressed individuals. We then systematically compared and integrated these raters' descriptions of the clients' self-states. In each case, we found a conflict between two internally incompatible states: an interpersonally submissive state and an interpersonally dominant one, a pattern consistent with the model's theoretical description of depression., (Copyright © 2010 Elsevier Ireland Ltd.

Child neurological diagnostic procedures involve extensive encounters with a multi-professional team and may have therapeutic effects. This study explored the therapeutic potential of the diagnostic process using the assimilation model as the conceptual frame of reference. The process of assimilation was tracked across nine consecutive encounters during the assessment of a 4-year-old girl who was referred to the child neurological team due to contact and communication problems. All parent-professional dialogues were transcribed and analyzed using dialogical sequence analysis, which yielded a core problematic reciprocal pattern that was named "controlling in relation to defiant and uncontrolled." Parent development in finding alternative patterns to excessive control was traced using the assimilation model. We could identify assimilation stages in parent development, from disowning the impact of their own actions and mainly seeing the problem as belonging to the child into a more flexible and self-related understanding of the problem. The parents also described more accommodating ways of managing the child at the follow-up. Benefits and limitations in applying the assimilation model in a non-therapy context are discussed.

The assimilation model is a theory of psychological change that depicts the self as a community of internal voices, composed of traces of the person's experiences. The model suggests that disconnection of certain voices from the community underlies many forms of psychopathology and psychological distress. Such problematic voices may be assimilated through psychotherapeutic dialogue by building meaning bridges. Meaning bridges are signs (e.g., words, images, gestures, narratives) that have similar meaning to author and addressee, that is, to the signs' producer and recipient, which may be different people or interacting internal voices. Building meaning bridges is thus a process of coming to terms with problematic voices, which reduces distress and gives access to experiential resources within the self. This article describes and illustrates meaning bridges, voices, signs, and associated concepts as elaborated in a program of research on the assimilation model.

This case study applied the assimilation model to examine the changing narrative of an outpatient with schizophrenia and symptoms of depression across a successful pharmacotherapy. The assimilation model describes how clients assimilate painful, problematic experiences. Therapeutic progress is understood to reflect increasing assimilation, measured by the Assimilation of Problematic Experiences Scale (APES). The authors used a 15-min semistructured interview (Problematic Experiences Questionnaire) to elicit narrative descriptions of the patient's problems and coping across five interviews throughout his 12-week treatment. They describe how the patient's narrative and APES ratings of his main problems by two clinicians changed in concert through treatment, explain these developments using assimilation concepts, and interpret the results in relation to assimilation and insight in schizophrenia.

This study aims to further the understanding of how innovative moments (IMs), which are exceptions to a client's problematic self-narrative in the therapy dialogue, progress to the construction of a new self-narrative, leading to successful psychotherapy. The authors' research strategy involved tracking IMs, and the themes expressed therein (or protonarratives), and analysing the dynamic relation between IMs and protonarratives within and across sessions using state space grids in a good-outcome case of constructivist psychotherapy. The concept of protonarrative helped explain how IMs transform a problematic self-narrative into a new, more flexible, self-narrative. The increased flexibility of the new self-narrative was manifested as an increase in the diversity of IM types and of protonarratives. Results suggest that new self-narratives may develop through the elaboration of protonarratives present in IMs, yielding an organizing framework that is more flexible than the problematic self-narrative.

According to the author's narrative model of change, clients may maintain a problematic self-stability across therapy, leading to therapeutic failure, by a mutual in-feeding process, which involves a cyclical movement between two opposing parts of the self. During innovative moments (IMs) in the therapy dialogue, clients' dominant self-narrative is interrupted by exceptions to that self-narrative, but subsequently the dominant self-narrative returns. The authors identified return-to-the-problem markers (RPMs), which are empirical indicators of the mutual in-feeding process, in passages containing IMs in 10 cases of narrative therapy (five good-outcome cases and five poor-outcome cases) with females who were victims of intimate violence. The poor-outcome group had a significantly higher percentage of IMs with RPMs than the good-outcome group. The results suggest that therapeutic failures may reflect a systematic return to a dominant self-narrative after the emergence of novelties (IMs).
