Rapid Generation of Somatic Mouse Mosaics with Locus-Specific, Stably Integrated Transgenic Elements.

In situ transgenesis methods such as viruses and electroporation can rapidly create somatic transgenic mice but lack control over copy number, zygosity, and locus specificity. Here we establish mosaic analysis by dual recombinase-mediated cassette exchange (MADR), which permits stable labeling of mutant cells expressing transgenic elements from precisely defined chromosomal loci. We provide a toolkit of MADR elements for combination labeling, inducible and reversible transgene manipulation, VCre recombinase expression, and transgenesis of human cells. Further, we demonstrate the versatility of MADR by creating glioma models with mixed reporter-identified zygosity or with "personalized" driver mutations from pediatric glioma. MADR is extensible to thousands of existing mouse lines, providing a flexible platform to democratize the generation of somatic mosaic mice. VIDEO ABSTRACT.

Practice-based evidence for spiritually integrated psychotherapies: Examining trajectories of psychological and spiritual distress.

The aims of this practice-based evidence study were to (a) examine clients' trajectories of psychological and spiritual distress over the course of spiritually integrated psychotherapies (SIPs) and (b) explore the role of varying types of spiritual interventions in these outcomes. In total, 164 practitioners of SIPs from 37 settings in a practice-research network administered the Clinically Adaptive Multidimensional Outcome Survey (Sanders et al., 2018) at each session with 1,227 clients and reported their use of theoretical orientations and spiritual interventions on an after-session summary checklist. Focusing on sessions over an initial 12-week period, latent growth curve modeling analyses revealed that clients, on average, experienced significant reduction of psychological distress during their engagement in SIPs with improvements occurring most sharply in the first month. Further, other findings revealed a salient reciprocal interplay with spiritual distress throughout treatment, such that clients who were struggling with their religious faith and/or spirituality were more psychologically distressed and displayed a more attenuated and gradual pattern of symptom reduction. In such cases, clinicians frequently utilized spiritual interventions involving basic skills (e.g., spiritual assessment), virtues (e.g., discuss self-control), and religious attachment (e.g., encourage acceptance of divine love) that were uniquely associated with clients' rate and duration of decline in psychological and spiritual distress. The present findings affirm the routine effectiveness of SIPs along with highlighting the potential value of certain spiritual interventions in supporting holistic recovery among clients who want clinicians to be culturally responsive to their spiritual and/or religious identities.

ECHO "Bootcamp": An Innovative Training Model to Onboard Providers in the Care of Gender Diverse Patients.

Purpose: Extension for Community Health Outcomes (ECHO) is a model of continuing medical education meant to connect academic medical center-based specialists with community providers to increase capacity in managing complex health conditions. The purpose of this study was to evaluate the effectiveness of a shortened "bootcamp" ECHO model in increasing participant competence with topics related to transgender and gender diverse (TGD) health care and the impact of "bootcamp" participation on enrollment in an ongoing ECHO series. Methods: An ongoing monthly ECHO series was instituted on topics of TGD health. After 2 years, the team implemented a four-session "bootcamp" for four consecutive weeks during March 2022 to introduce foundational topics for new participants who had joined or were considering joining the ongoing series. Qualitative and quantitative results were collected from self-reported pre-/post-surveys as well as from in-session quizzes. Results: There were 71 participants in the "bootcamp" including health care providers and support staff. Attendees reported a 10.3% increase (p = 0.02) in self-reported comfort providing care to transgender patients. Pre-/post-knowledge improved in areas of health inequities (50% vs. 74% correct pre/post), surgical requirements (33% vs. 74%), and effects of masculinizing (55% vs. 70%) and feminizing (64% vs. 89%) hormone therapy. Prescribing providers reported a significant change across four areas of practice competency. Among 71 "bootcamp" participants, 15 registered for the ongoing program. Conclusion: Use of a "bootcamp" highlights ways to increase participant comfort and knowledge in providing TGD health care in a shortened timeframe and recruit new participants to an ongoing ECHO curriculum.

First impressions matter: The influence of initial assessments on psychological treatment initiation and subsequent dropout.

OBJECTIVE: This study investigated if patients' experience of an initial assessment may be associated with outcome expectations, and with subsequent treatment attendance. METHOD: The sample comprised n = 6051 patients with depression/anxiety disorders, nested within k = 148 assessing therapists. Multilevel modelling (MLM) was used to examine therapist effects on treatment initiation and subsequent dropout, adjusting for patient-level characteristics. We tested associations between early outcome expectancy measured at an initial assessment with attendance at a first therapy session, and with dropout after initiation. Variability in mean expectancy ratings in the caseloads of assessing therapists was examined using the intracluster correlation coefficient (ICC). RESULTS: Therapist effects partly explained the variance in treatment initiation and dropout. Pre-treatment outcome expectations significantly predicted treatment initiation but not dropout for the subgroup of patients who started treatment. Approximately 16% of variability in mean expectancy ratings was explained by therapist effects (ICC = 0.159) after controlling for patient-level covariates. CONCLUSIONS: Patients assessed by some therapists are more likely to have higher outcome expectations, which influences their decision to initiate treatment thereafter. Once patients start therapy, early expectancy measured at assessment no longer influences their attendance, but the "first impression" from an initial assessment does influence their subsequent likelihood of dropout.

Individual treatment selection for patients with post-traumatic stress disorder: External validation of a personalised advantage index.

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.

Telephone treatments in Improving Access to Psychological Therapies services: an analysis of use and impact on treatment uptake.

BACKGROUND: There is debate about how best to increase access to psychological therapy and deliver mental healthcare effectively and efficiently at a national level. One trend is the increased use of the telephone to deliver therapy. However, there is the potential to disadvantage certain patient groups and/or impact on uptake of help. This study aims to answer three questions: (i) Which factors are associated with being offered an assessment by telephone? (ii) Which factors are associated with attendance at assessment? and (iii) What is the impact of an assessment by telephone on subsequent treatment appointment? METHODS: Routine outcome data was provided by seven UK Improving Access to Psychological Therapy services. The analysis sample comprised 49,923 patients who referred to 615 general practices in 2017. Multilevel modelling, including service and GP practice as random factors, was used to answer the three research questions. RESULTS: The offer of an initial assessment by telephone was strongly associated with local service configuration. Patient self-referral, a shorter wait, greater age and lower deprivation were associated with attendance at assessment and subsequent treatment session. Telephone mode assessment had no impact on the uptake of the assessment but may influence the uptake of further treatment if this was also by telephone. The practitioner carrying out the assessment had a significant effect on subsequent treatment uptake. CONCLUSION: Offering telephone assessments does not have a negative impact on uptake of assessment and services may benefit by facilitating and integrating telephone assessments into their systems. The COVID-19 pandemic has accelerated the use of telephone and other remote means of delivery, and results from this study can inform services to consider how best to re-configure post-pandemic.

Test-retest stability, convergent validity, and sensitivity to change for the Goal-Based Outcome tool for adolescents: Analysis of data from a randomized controlled trial.

OBJECTIVE(S): To examine the psychometric properties of the idiographic Goal-Based Outcome (GBO) tool for young people: test-retest stability, convergent validity, and sensitivity to an intervention. METHODS: This measure validation study used data from a randomized controlled trial of school-based humanistic counseling. We used multilevel analyses to assess test-retest stability, convergent validity of the GBO tool against nomothetic measures of mental wellbeing, and sensitivity to an intervention. RESULTS: The GBO tool showed acceptable stability over a 6-24 week period; moderate convergent validity with nomothetic measures of mental well-being, self-esteem, and depression; and greater sensitivity to an intervention than a measure of psychological distress. CONCLUSIONS: The GBO tool shows evidence of having acceptable psychometric properties and is suitable for monitoring change on individual goals. It may also have the capacity to function as a population-level indicator of outcomes in conjunction with the use of other measures of mental health and wellbeing.

Applying precision methods to treatment selection for moderate/severe depression in person-centered experiential therapy or cognitive behavioral therapy.

OBJECTIVE: To develop two prediction algorithms recommending person-centered experiential therapy (PCET) or cognitive-behavioral therapy (CBT) for patients with depression: (1) a full data model using multiple trial-based and routine variables, and (2) a routine data model using only variables available in the English NHS Talking Therapies program. METHOD: Data was used from the PRaCTICED trial comparing PCET vs. CBT for 255 patients meeting a diagnosis of moderate or severe depression. Separate full and routine data models were derived and the latter tested in an external data sample. RESULTS: The full data model provided the better prediction, yielding a significant difference in outcome between patients receiving their optimal vs. non-optimal treatment at 6- (Cohen's d = .65 [.40, .91]) and 12 months (d = .85 [.59, 1.10]) post-randomization. The routine data model performed similarly in the training and test samples with non-significant effect sizes, d = .19 [-.05, .44] and d = .21 [-.00, .43], respectively. For patients with the strongest treatment matching (d ≥ 0.3), the resulting effect size was significant, d = .38 [.11, 64]. CONCLUSION: A treatment selection algorithm might be used to recommend PCET or CBT. Although the overall effects were small, targeted matching yielded somewhat larger effects.

Implementation of an Intensive Telehealth Intervention for Rural Patients with Clinic-Refractory Diabetes.

BACKGROUND: Rural patients with type 2 diabetes (T2D) may experience poor glycemic control due to limited access to T2D specialty care and self-management support. Telehealth can facilitate delivery of comprehensive T2D care to rural patients, but implementation in clinical practice is challenging. OBJECTIVE: To examine the implementation of Advanced Comprehensive Diabetes Care (ACDC), an evidence-based, comprehensive telehealth intervention for clinic-refractory, uncontrolled T2D. ACDC leverages existing Veterans Health Administration (VHA) Home Telehealth (HT) infrastructure, making delivery practical in rural areas. DESIGN: Mixed-methods implementation study. PARTICIPANTS: 230 patients with clinic-refractory, uncontrolled T2D. INTERVENTION: ACDC bundles telemonitoring, self-management support, and specialist-guided medication management, and is delivered over 6 months using existing VHA HT clinical staffing/equipment. Patients may continue in a maintenance protocol after the initial 6-month intervention period. MAIN MEASURES: Implementation was evaluated using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. The primary effectiveness outcome was hemoglobin A1c (HbA1c). KEY RESULTS: From 2017 to 2020, ACDC was delivered to 230 patients across seven geographically diverse VHA sites; on average, patients were 59 years of age, 95% male, 80% white, and 14% Hispanic/Latinx. Patients completed an average of 10.1 of 12 scheduled encounters during the 6-month intervention period. Model-estimated mean baseline HbA1c was 9.56% and improved to 8.14% at 6 months (- 1.43%, 95% CI: - 1.64, - 1.21; P < .001). Benefits persisted at 12 (- 1.26%, 95% CI: - 1.48, - 1.05; P < .001) and 18 months (- 1.08%, 95% CI - 1.35, - 0.81; P < .001). Patients reported increased engagement in self-management and awareness of glycemic control, while clinicians and HT nurses reported a moderate workload increase. As of this submission, some sites have maintained delivery of ACDC for up to 4 years. CONCLUSIONS: When strategically designed to leverage existing infrastructure, comprehensive telehealth interventions can be implemented successfully, even in rural areas. ACDC produced sustained improvements in glycemic control in a previously refractory population.

Early response as a prognostic indicator in person-centered experiential therapy for depression.

Currently, no reports exist on the phenomenon of early response in humanistic-experiential therapies. This study investigated the prognostic value of early response on posttreatment outcomes in person-centered experiential therapy (PCET) for depression within the English Improving Access to Psychological Therapies program. The design of the study was a retrospective observational cohort study. Routine clinical data were drawn from N = 3,321 patients with depression symptoms. The primary outcome was reliable and clinically significant improvement (RCSI) on the Patient Health Questionnaire-9 (PHQ-9) self-report depression measure at the end of treatment. Early response was operationalized as reliable improvement, defined as a PHQ-9 change score ≥ 6 from baseline to Session 4. Early response was examined as a predictor of RCSI using logistic regression controlling for baseline depression severity. In sensitivity analyses, therapist effects were controlled using multilevel modeling. A total of 38.7% of patients met the criterion for early response. Patients who experienced an early response to treatment were six times more likely to recover at the end of treatment compared to patients who did not have an early response. The early response effect was still evident after accounting for individual variability between therapists. However, a quarter of patients displayed a pattern of eventual response, reaching recovery at end of treatment despite not experiencing an initial improvement early in therapy. Early response to PCET is a reliable predictor of treatment outcome. Different response patterns evidenced in this study indicate that identifying subgroups of patients associated with early and eventual response could support clinical decision-making.

Potential unrealized mortality benefit of glucagon-like peptide-1 receptor agonists and sodium-glucose co-transport-2 inhibitors: A report from the Veterans Health Administration Clinical Assessment, Reporting and Tracking program.

AIM: To assess the unrealized potential of glucagon-like peptide-1 receptor agonist (GLP-1RA) or sodium-glucose co-transport-2 inhibitor (SGLT2i) use to reduce mortality in veterans with type 2 diabetes (T2D), coronary artery disease (CAD), and other characteristics congruent with clinical trial cohorts that established the efficacy of these agents. METHODS: Veterans with T2D and CAD on angiography in 2014 who were untreated with either a GLP-1RA or a SGLT2i were assessed for key eligibility criteria of the LEADER (GLP-1RA) and EMPA-REG OUTCOME (SGLT2i) trials. Trial hazard ratios and 95% confidence intervals for all-cause death were applied to deaths observed in veterans through 2018 to estimate the potential benefit of GLP-1RA or SGLT2i use. RESULTS: Median observation was 4.3 years. Of 15 987 veterans with T2D and CAD, 1186 (7.4%) were excluded for GLP-1RA or SGLT2i treatment, and 1386 lacked glycated haemoglobin measurement. Of the remaining 13 415 patients, 4103 (30.1%) and 5313 (39.6%) fulfilled the key criteria for the LEADER and EMPA-REG OUTCOME trials, respectively. Death occurred in 1009 (24.6%) of LEADER-eligible patients and 1335 (25.1%) of EMPA-REG OUTCOME-eligible patients. Under treatment with liraglutide in LEADER-eligible veterans, a 3.5% (0.7%-6.2%) potential absolute mortality reduction, corresponding to 144 (28-253) fewer deaths (0.88 [0.17-1.56] per 100 person-years), might have been expected. Similarly, under treatment with empagliflozin in EMPA-REG OUTCOME-eligible veterans, a 7.9% (4.5%-10.8%) potential absolute mortality reduction, corresponding to 418 (230-573) fewer deaths (1.98 [1.14-2.72] per 100 person-years), might have been expected. CONCLUSIONS: This analysis indicates unrealized opportunities to reduce mortality in selected veterans with T2D and CAD via increased GLP-1RA and SGLT2i use.

A randomized, controlled pilot study of cognitive analytic therapy for stressed pregnant women with underlying anxiety and depression in a routine health service setting.

A pilot study of cognitive analytic therapy (CAT) plus treatment as usual (TAU), versus TAU in stressed pregnant women with anxiety and depression, was undertaken as an essential preliminary to any definitive, randomized controlled trial (RCT). The trial was pragmatic, multicentre, parallel, randomized, controlled, and unblinded. Participants were pregnant women screened using the Hospital Anxiety and Depression Scale (HADS). Treatment was standard 16-session CAT. Main outcome measures were Spielberger State/Trait Anxiety Inventory (STAI) (primary outcome measure) at 24 weeks after randomization, therefore 1 month after therapy for the CAT group; HADS; Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM); Edinburgh Postnatal Depression Scale (EPDS); 36-item Short Form Health Survey (SF-36); and a brief Experiences of Therapy Questionnaire, completed at baseline and on average at 12, 24, 40, and 82 weeks after randomization. Thirty-nine patients (CAT + TAU, n = 20; TAU, n = 19) were randomized with mean baseline STAI State scores of 50.8 (SD 11.4) and 51.1 (SD 13.3), respectively. Sixteen patients had missing primary outcome data leaving 23 (n = 11 and n = 12) patients for analysis. The mean STAI State score was 38.5 (SD 13.8) and 45.7 (SD 16.8) in the CAT and TAU groups respectively at 24 weeks after randomization, with an adjusted difference in means of 7.2 (95% confidence interval [CI]: -7.9 to 20.6). No safety issues were reported. Patient retention for the CAT group was high (18/20; 90% of patients completed therapy). Ten out of 11 (90.9%) respondents 'agreed' or 'strongly agreed' that having CAT had been 'very helpful'. The study demonstrated the feasibility of safely undertaking CAT in this setting. Outcomes showed positive trends compatible with a clinically important effect, although statistically definitive conclusions cannot be drawn in such a study.

Therapist effects vary significantly across psychological treatment care sectors.

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.

A Toolbox Approach to Obesity Treatment in Urban Safety-Net Primary Care Clinics: a Pragmatic Clinical Trial.

BACKGROUND: There is a need for new strategies to improve the success of obesity treatment within the primary care setting. OBJECTIVE: To determine if patients offered low out-of-pocket cost weight management tools achieved more weight loss compared to usual care. DESIGN: Twelve-month pragmatic clinical weight loss trial with a registry-based comparator group performed in primary care clinics of an urban safety-net hospital. PARTICIPANTS: From a large clinical registry, we randomly selected 428 patients to have the opportunity to receive the intervention. INTERVENTIONS: Medical weight management tools-partial meal replacements, recreation center vouchers, pharmacotherapy, commercial weight loss program vouchers, and a group behavioral weight loss program-for $5 or $10 monthly. Patients chose their tools, could switch tools, and could add a second tool at 6 months. MAIN MEASURES: The primary outcome was the proportion of intervention-eligible patients who achieved ≥ 5% weight loss. The main secondary outcome was the proportion of on-treatment patients who achieved ≥ 5% weight loss. KEY RESULTS: Overall, 71.3% (305 of 428) had available weight measurement data/PCP visit data to observe the primary outcome. At 12 months, 23.3% (71 of 305) of intervention-eligible participants and 15.7% (415 of 2640) of registry-based comparators had achieved 5% weight loss (p < 0.001). Of the on-treatment participants, 34.5% (39 of 113) achieved 5% weight loss. Mean percentage weight loss was - 3.15% ± 6.41% for on-treatment participants and - 0.30% ± 6.10% for comparators (p < 0.001). The initially preferred tools were meal replacements, pharmacotherapy, and recreation center passes. CONCLUSIONS: Access to a variety of low out-of-pocket cost weight management tools within primary care resulted in ≥ 5% body weight loss in approximately one quarter of low-income patients with obesity.

Structured lifestyle education for people with schizophrenia, schizoaffective disorder and first-episode psychosis (STEPWISE): randomised controlled trial.

BACKGROUND: Obesity is a major challenge for people with schizophrenia.AimsWe assessed whether STEPWISE, a theory-based, group structured lifestyle education programme could support weight reduction in people with schizophrenia. METHOD: In this randomised controlled trial (study registration: ISRCTN19447796), we recruited adults with schizophrenia, schizoaffective disorder or first-episode psychosis from ten mental health organisations in England. Participants were randomly allocated to the STEPWISE intervention or treatment as usual. The 12-month intervention comprised four 2.5 h weekly group sessions, followed by 2-weekly maintenance contact and group sessions at 4, 7 and 10 months. The primary outcome was weight change after 12 months. Key secondary outcomes included diet, physical activity, biomedical measures and patient-related outcome measures. Cost-effectiveness was assessed and a mixed-methods process evaluation was included. RESULTS: Between 10 March 2015 and 31 March 2016, we recruited 414 people (intervention 208, usual care 206) with 341 (84.4%) participants completing the trial. At 12 months, weight reduction did not differ between groups (mean difference 0.0 kg, 95% CI -1.6 to 1.7, P = 0.963); physical activity, dietary intake and biochemical measures were unchanged. STEPWISE was well-received by participants and facilitators. The healthcare perspective incremental cost-effectiveness ratio was £246 921 per quality-adjusted life-year gained. CONCLUSIONS: Participants were successfully recruited and retained, indicating a strong interest in weight interventions; however, the STEPWISE intervention was neither clinically nor cost-effective. Further research is needed to determine how to manage overweight and obesity in people with schizophrenia.Declaration of interestR.I.G.H. received fees for lecturing, consultancy work and attendance at conferences from the following: Boehringer Ingelheim, Eli Lilly, Janssen, Lundbeck, Novo Nordisk, Novartis, Otsuka, Sanofi, Sunovion, Takeda, MSD.

D2 dopamine receptor activation induces female preference for male song in the monogamous zebra finch.

The evolutionary conservation of neural mechanisms for forming and maintaining pair bonds is unclear. Oxytocin, vasopressin and dopamine (DA) transmitter systems have been shown to be important in pair-bond formation and maintenance in several vertebrate species. We examined the role of dopamine in formation of song preference in zebra finches, a monogamous bird. Male courtship song is an honest signal of sexual fitness; thus, we measured female song preference to evaluate the role of DA in mate selection and pair-bond formation, using an operant conditioning paradigm. We found that DA acting through the D2 receptor, but not the D1 receptor, can induce a song preference in unpaired female finches and that blocking the D2 receptor abolished song preference in paired females. These results suggest that similar neural mechanisms for pair-bond formation are evolutionarily conserved in rodents and birds.

Associations between therapists' occupational burnout and their patients' depression and anxiety treatment outcomes.

BACKGROUND: Occupational burnout is common in mental health professionals, but its impact on patient outcomes is as yet uncertain. This study aimed to investigate associations between therapist-level burnout and patient-level treatment outcomes after psychological therapy. METHODS: We used multilevel modeling using depression (PHQ-9) and anxiety (GAD-7) outcomes data from 2,223 patients nested within 49 therapists. Therapists completed a survey including the Oldenburg Burnout Inventory (OLBI) and a job satisfaction scale (JDSS). RESULTS: After controlling for case-mix, around 5% of variability in treatment outcomes was explained by therapist effects (TE). Higher therapist OLBI-disengagement and lower JDSS scores were significantly associated with poorer treatment outcomes, explaining between 31 and 39% of the TE estimate. Higher OLBI scores were also correlated with lower job satisfaction ratings. CONCLUSIONS: Therapist burnout has a negative impact on treatment outcomes and could be the target of future preventive and remedial action.

The effectiveness of high-intensity CBT and counselling alone and following low-intensity CBT: a reanalysis of the 2nd UK National Audit of Psychological Therapies data.

BACKGROUND: A previously published article in this journal reported the service effects from 103 services within the UK Improving Access to Psychological Therapies (IAPT) initiative and the comparative effectiveness of CBT and Counselling provision. All patients received High-intensity CBT or High-intensity Counselling, but some also received Low-intensity CBT before being stepped-up to High intensity treatments. The report did not distinguish between patients who received low-intensity CBT before being stepped-up. This article clarifies the basis for collapsing low- and high-intensity interventions by analysing the four treatment conditions separately. METHOD: Data from 33,243 patients included in the second round of the National Audit of Psychological Therapies (NAPT) were re-analysed as four separate conditions: High-intensity CBT only (n = 5975); High-intensity Counselling only (n = 3003); Low-intensity CBT plus High-intensity CBT (n = 17,620); and Low-intensity CBT plus High-intensity Counselling (n = 6645). Analyses considered levels of pre-post therapy effect sizes (ESs), reliable improvement (RI) and reliable and clinically significant improvement (RCSI). Multilevel modelling was used to model predictors of outcome, namely patient pre-post change on PHQ-9 scores at last therapy session. RESULTS: Significant differences obtained on various outcome indices but were so small they carried no clinical significance. Including the four treatment groups in a multilevel model comprising patient intake severity, patient ethnicity and number of sessions attended showed no significant differences between the four treatment groups. Comparisons between the two high-intensity interventions only (N = 8978) indicated Counselling showed more improvement than CBT by 0.3 of a point on PHQ-9 for the mean number of sessions attended. However, this result was moderated by the number of sessions and for 12 or more sessions, the advantage went to CBT. CONCLUSIONS: This re-analysis showed no evidence of clinically meaningful differences between the four treatment conditions using standard indices of patient outcomes. However, a differential advantage to high-intensity Counselling for fewer than average sessions attended and high-intensity CBT for more than average sessions attended has important service implications. The finding of equivalent outcomes between high-intensity CBT and Counselling for more severe patients also has important policy implications. Empirically-informed procedures (e.g., predictive modelling) for assigning patients to interventions need to be considered to improve patient outcomes.

The comparative effectiveness and efficiency of cognitive behaviour therapy and generic counselling in the treatment of depression: evidence from the 2nd UK National Audit of psychological therapies.

BACKGROUND: Cognitive Behaviour Therapy (CBT) is the front-line psychological intervention for step 3 within UK psychological therapy services. Counselling is recommended only when other interventions have failed and its effectiveness has been questioned. METHOD: A secondary data analysis was conducted of data collected from 33,243 patients across 103 Improving Access to Psychological Therapies (IAPT) services as part of the second round of the National Audit of Psychological Therapies (NAPT). Initial analysis considered levels of pre-post therapy effect sizes (ESs) and reliable improvement (RI) and reliable and clinically significant improvement (RCSI). Multilevel modelling was used to model predictors of outcome, namely patient pre-post change on PHQ-9 scores at last therapy session. RESULTS: Counselling received more referrals from patients experiencing moderate to severe depression than CBT. For patients scoring above the clinical cut-off on the PHQ-9 at intake, the pre-post ES (95% CI) for CBT was 1.59 (1.58, 1.62) with 46.6% making RCSI criteria and for counselling the pre-post ES was 1.55 (1.52, 1.59) with 44.3% of patients meeting RCSI criteria. Multilevel modelling revealed a significant site effect of 1.8%, while therapy type was not a predictor of outcome. A significant interaction was found between the number of sessions attended and therapy type, with patients attending fewer sessions on average for counselling [M = 7.5 (5.54) sessions and a median (IQR) of 6 (3-10)] than CBT [M = 8.9 (6.34) sessions and a median (IQR) of 7 (4-12)]. Only where patients had 18 or 20 sessions was CBT significantly more effective than counselling, with recovery rates (95% CIs) of 62.2% (57.1, 66.9) and 62.4% (56.5, 68.0) respectively, compared with 44.4% (32.7, 56.6) and 42.6% (30.0, 55.9) for counselling. Counselling was significantly more effective at two sessions with a recovery rate of 34.9% (31.9, 37.9) compared with 22.2% (20.5, 24.0) for CBT. CONCLUSIONS: Outcomes for counselling and CBT in the treatment of depression were comparable. Research efforts should focus on factors other than therapy type that may influence outcomes, namely the inherent variability between services, and adopt multilevel modelling as the given analytic approach in order to capture the naturally nested nature of the implementation and delivery of psychological therapies. It is of concern that half of all patients, regardless of type of intervention, did not show reliable improvement.
