Are patient expectations still relevant for psychotherapy process and outcome?

mHealth: a mechanism to deliver more accessible, more effective mental health care

The increased popularity and functionality of mobile devices has a number of implications for the delivery of mental health services. Effective use of mobile applications has the potential to (a) increase access to evidence-based care; (b) better inform consumers of care and more actively engage them in treatment; (c) increase the use of evidence-based practices; and (d) enhance care after formal treatment has concluded. The current paper presents an overview of the many potential uses of mobile applications as a means to facilitate ongoing care at various stages of treatment. Examples of current mobile applications in behavioural treatment and research are described, and the implications of such uses are discussed. Finally, we provide recommendations for methods to include mobile applications into current treatment and outline future directions for evaluation.

KEY PRACTITIONER MESSAGE

Mobile devices are becoming increasingly common among the adult population and have tremendous potential to advance clinical care. Mobile applications have the potential to enhance clinical care at stages of treatment-from engaging patients in clinical care to facilitating adherence to practices and in maintaining treatment gains. Research is needed to validate the efficacy and effectiveness of mobile applications in clinical practice. Research on such devices must incorporate assessments of usability and adherence in addition to their incremental benefit to treatment.

The role of pretreatment outcome expectancies and cognitive-behavioral skills in symptom improvement in an acute psychiatric setting

BACKGROUND

Prior research has found that pretreatment expectations of symptom improvement are positively correlated with depressive symptom change. The current investigation extends previous research by examining whether pretreatment outcome expectancies predict symptom change across several diagnostic categories within the context of an acute, naturalistic psychiatric setting.

METHODS

Analyses were conducted to examine whether pretreatment outcome expectancies (credibility/expectancy questionnaire [CEQ]) predicted symptom improvement within major depression (N=420), bipolar disorder (N=120) and psychosis (N=36). Bootstrap mediation analyses were conducted to examine whether acquisition of cognitive behavioral therapy (CBT) skills (cognitive behavior therapy skills questionnaire [CBTSQ]) may mediate expectancy-outcome relations.

RESULTS

Results indicated a differential pattern of associations across diagnoses. Patient CBT skills emerged as a significant mediator of expectancy-outcome relations, but only in the major depression group. Both behavioral and cognitive skills were significantly, and independently, associated with symptom improvement.

LIMITATIONS

Sample sizes were small in the bipolar manic subgroup and psychosis group. CBT skills and symptom measures were assessed at concurrent time points.

CONCLUSIONS

The present findings suggest that patient expectancies and CBT skills may have a differential impact on symptom change as a function of diagnostic category. The implication of these results and directions for future research are discussed.

The role of the therapeutic relationship in cognitive behaviour therapy for chronic fatigue syndrome

Cognitive behaviour therapy (CBT) for chronic fatigue syndrome (CFS) can reduce fatigue and impairment. Recently, it was found that changes in fatigue-perpetuating factors, i.e. focusing on symptoms, control over fatigue, perceived activity and physical functioning, are associated with and explain up to half of the variance in fatigue during CBT for CFS. The therapy relationship, e.g. outcome expectations and working alliance, may also contribute to treatment outcome. We aimed to examine the role of the therapy relationship in CBT and determine whether it exerts its effect independently of changes in fatigue-perpetuating factors. We used a cohort of 217 CFS patients in which the pattern of change in fatigue-perpetuating factors was examined previously. Fatigue, therapy relationship and fatigue-perpetuating factors were measured at the start of therapy, three times during CBT and at the end of therapy. Baseline outcome expectations and agreement about the content of therapy predicted post therapy fatigue. A large part of the variance in post-treatment fatigue (25%) was jointly explained by outcome expectations, working alliance and changes in fatigue-perpetuating factors. From this, we conclude that positive outcome expectations and task agreement seem to facilitate changes in fatigue-perpetuating factors during CBT for CFS. It is therefore important to establish a positive therapy relationship early in therapy.

Pre-treatment shyness mindset predicts less reduction of social anxiety during exposure therapy

This study examined the moderating role of shyness mindset on the reduction of social anxiety during exposure-based treatment. Participants (N=60) in an intensive outpatient program for anxiety disorders were assessed at pre- and post-treatment. Social performance anxiety decreased dramatically during treatment, but the amount of decrease differed as a function of pre-treatment shyness mindset. At one standard deviation above the mean on both the social performance anxiety and shyness mindset measures, an average reduction of 15 points on the social performance anxiety measure was observed. At one standard deviation above the mean on the social performance anxiety measure and one standard deviation below the mean on the shyness mindset measure, an average reduction of 27 points on the social performance anxiety measure was observed. These results suggest that targeting shyness mindset during exposure-based treatments for social anxiety disorder might increase the effectiveness of treatment for individuals with a high shyness mindset.

A preliminary study of motivational interviewing as a prelude to intensive treatment for an eating disorder

BACKGROUND

Engaging patients with an eating disorder in change is difficult and intensive treatment programs have high drop-out rates. The purpose of the study was to determine whether Motivational Interviewing (MI) in the form of a brief, pre-treatment intervention would be associated with higher completion rates in subsequent intensive treatment for an eating disorder. Thirty-two participants diagnosed with an eating disorder participated in the study. All participants were on the waitlist for admission to an intensive, hospital-based treatment program. Sixteen participants were randomly assigned to four individual sessions of MI that began prior to entrance into the treatment program (MI condition) and 16 participants were assigned to treatment as usual (control condition). The main outcome was completion of the intensive treatment program. Participants also completed self-report measures of motivation to change.

RESULTS

Participants in the MI condition were significantly more likely to complete intensive treatment (69% completion rate) than were those in the control condition (31%).

CONCLUSIONS

MI can be a useful intervention to engage individuals with severe eating disorders prior to participation in intensive treatment. MI as a brief prelude to hospital-based treatment for an eating disorder may help to improve completion rates in such programs. Further research is required to determine the precise therapeutic mechanisms of change in MI.

The power of belief and expectancy in understanding and management of depression

This article examines how beliefs can influence the definition, classification, understanding, and treatment of depression. It is organized in five parts: The first part critically reviews the definition of depression; the second part explores the medicalization of depression; the third part examines the role of the pharmaceutical industry in the promotion and marketing of antidepressant medications; the fourth part surveys the psychological therapies for depression and examines the role of expectancy in outcome; and the last part looks at the mechanisms involved in the placebo effect. A list of evidence-based strategies, including hypnosis, are discussed in the context of cognitive hypnotherapy for depression to illustrate how expectancy effect can be maximized in psychotherapy.

Monitoring mindfulness practice quality: an important consideration in mindfulness practice

Mindfulness-Based Stress Reduction (MBSR) is an experientially based group intervention empirically supported to reduce psychological symptomology. Although MBSR has shown to be an effective intervention, little is known about which facets of the intervention are important in producing positive outcomes. This study tested several aspects of mindfulness practice (total practice duration, practice frequency and practice quality) with the primary focus being on validating (i.e., predictive and convergent validity) a new measure of mindfulness practice quality (PQ-M). The PQ-M fit a two-factor solution via a Maximum Likelihood Exploratory Factor Analysis (n=99). Using longitudinal multilevel modeling on a smaller subsample (n=19), preliminary support was found for changes in practice quality over the course of the MBSR intervention. Further, change in practice quality was associated with improvements in psychological symptoms. While this study was exploratory, these findings suggest that practice quality is a relevant factor to promote positive outcomes and may guide mindfulness instructors in providing highly tailored interventions.

Compensation and treatment: disability benefits and outcomes of U.S. veterans receiving residential PTSD treatment

The U.S. Department of Veterans Affairs (VA) provides specialized intensive posttraumatic stress disorder (PTSD) programs to treat trauma-related symptoms in addition to providing service-connected disability to compensate veterans for injury sustained while serving in the military. Given the percentage of veterans who are receiving treatment for PTSD, in addition to seeking compensation for PTSD, a debate has emerged about the impact of compensation on symptom recovery. This study examined the associations among status of compensation, treatment expectations, military cohort, length of stay, and outcomes for 776 veterans who were enrolled in 5 VA residential PTSD programs between the years of 2005 and 2010. Mixed model longitudinal analyses, with age, gender, and baseline symptoms nested within treatment site in the model, found that treatment expectations were modestly predictive of treatment outcomes. Veterans seeking increased compensation reported marginally lower treatment expectations (d = .008), and did not experience poorer outcomes compared to veterans not seeking increased compensation with the effect of baseline symptoms partialled out. Veterans from the era of the Iraq and Afghanistan conflicts reported lower treatment expectations (d = .020) and slightly higher symptoms at intake (d = .021), but had outcomes at discharge equivalent to veterans from other eras with baseline symptoms partialled out. These findings help further inform the debate concerning disability benefits and symptom changes across time.

College Athletes’ Expectations About Injury Rehabilitation With an Athletic Trainer

Context:

Injured athletes begin the rehabilitation process with expectations about the nature of the working relationship with an athletic trainer. These expectations can infuence the effectiveness of the assistance provided.

Objective:

To determine whether male and female athletes differed in terms of expectations about injury rehabilitation services with an athletic trainer.

Design:

A questionnaire was administered to student athletes that assessed expectations about injury rehabilitation. Setting: Five colleges and universities.

Patients or Other Participants:

Questionnaire responses were provided by 679 student athletes (443 males and 236 females).

Main Outcome Measure:

Responses to the Expectations about Athletic Training questionnaire were used to assess factors identifed as Personal Commitment, Facilitative Conditions, Athletic Trainer Expertise, and Realism.

Results:

A statistically signifcant interaction between gender and prior experience was identifed. Male athletes with no prior experience had lower expectations for a facilitative environment. Female athletes with prior experience were less likely to have realistic expectations.

Conclusions:

Gender and prior experience infuence athletes’ expectations of injury rehabilitation with an athletic trainer.

The acute effects of exercise on cigarette cravings, withdrawal symptoms, affect, and smoking behaviour: systematic review update and meta-analysis

RATIONALE

Smoking cessation is associated with cigarette cravings and tobacco withdrawal symptoms (TWS), and exercise appears to ameliorate many of these negative effects. A number of studies have examined the relationships between exercise, cigarette cravings, and TWS.

OBJECTIVES

The objectives of this study were (a) to review and update the literature examining the effects of short bouts of exercise on cigarette cravings, TWS, affect, and smoking behaviour and (b) to conduct meta-analyses of the effect of exercise on cigarette cravings.

METHODS

A systematic review of all studies published between January 2006 and June 2011 was conducted.

RESULTS

Fifteen new studies were identified, 12 of which found a positive effect of exercise on cigarette cravings. The magnitude of statistically significant effect sizes for 'desire to smoke' and 'strength of desire to smoke' ranged from 0.4 to 1.98 in favour of exercise compared to passive control conditions, and peaked either during or soon after treatment. Effects were found up to 30 min post-exercise. Cigarette cravings were reduced following exercise with a wide range of intensities from isometric exercise and yoga to activity as high as 80-85 % heart rate reserve. Meta-analyses revealed weighted mean differences of -1.90 and -2.41 in 'desire to smoke' and 'strength of desire to smoke' outcomes, respectively. Measures of TWS and negative affect were reduced following light-moderate intensity exercise, but increased during vigorous exercise.

CONCLUSIONS

Exercise can have a positive effect on cigarette cravings and TWS. However, the most effective exercise intensity to reduce cravings and the underlying mechanisms associated with this effect remain unclear.

Suggestion, Cognition, and Behavior

Deliberate and nondeliberate suggestions can influence cognitions and behaviors in surprising ways. Sometimes suggestions are helpful and improve our cognitions and behaviors, but at other times they are harmful. Suggestions can create response expectancies: the myriad ways in which we anticipate responding automatically to various situations. In this article, we discuss some of the most recent and intriguing reported effects of suggestion on cognition and behavior—effects that should make us stop and wonder, but should also make us reflect on the possibility that other well-known findings are the result of suggestion and expectation. The boundaries and underlying mechanisms of the effects of suggestion are puzzles waiting to be solved.

Who benefits most from guided self-help for binge eating? An investigation into the clinical features of completers and non-completers

Guided self-help (GSH) is a recommended first step in treatment for bulimia nervosa (BN) and binge eating disorder (BED) (NICE, 2004). It remains unclear what makes some individuals more likely to respond to this form of treatment than others. Forty-eight patients participated in this study using a GSH programme for binge eating. Profiles of treatment completers and non-completers are compared, and reasons for non-completion explored. Completion of treatment was associated with significant improvements in mood, general functioning and on measures of dietary restraint, frequency of objective binge eating (OBE), laxative misuse, self-induced vomiting (SIV) and driven exercise. Improvements were maintained at follow-up. Treatment non-completers reported significantly higher pre-treatment levels of depression and weight concern, and lower levels of general health and vitality. Reasons for discontinuing treatment were related to perceptions of the GSH programme; practicalities of the programme; and readiness to change. Whilst GSH can be effective for a sub-group of patients, factors such as pre-morbid level of depression, degree of weight concern, perceptions of the programme, and readiness to change may increase the likelihood of non-completion.

The 2011 Leona Tyler Award Address

A debate exists about whether the common factors or specific ingredients are critical to producing the benefits of psychotherapy. A model of the relationship, based on evolved human characteristics related to healing, is presented that integrates common factors and specific ingredients. After the initial bond is formed, the relationship involves three healing aspects: the real relationship, the creation of expectations, and participation in healthy actions.

An exploratory study of inducing positive expectancies for psychotherapy

OBJECTIVES

The goal of this study was to determine whether explicit presentation of outcome data about the effectiveness of psychotherapy among older adults increased positive expectancy for treatment.

METHOD

The study included an ethically diverse sample of 50 adults over age 60 who screened positive for depression and agreed to participate in the BRIGHTEN Program, an interdisciplinary geriatric mental health program. Prior to treatment initiation, we presented participants with outcome data about psychotherapy, asked participants to rate and respond to the data, and asked participants about prior experience with mental health treatment. These data were collected via semi-structured interviews.

RESULTS

Higher importance ratings for the outcome data were significantly associated with starting psychotherapy (r = 0.30, p = 0.04). Depression severity predicted importance assigned to the outcome data (ß = 0.36, p = 0.03), more severely depressed participants rated the outcome data as more important. Qualitative analyses indicated that the presentation of outcome data increased hopefulness for successful treatment. In a hierarchical regression analysis, hopefulness in the data predicted data importance ratings, above and beyond the influence of depression severity (ß = 0.50, p < 0.01).

CONCLUSION

Our results suggest that information about the effectiveness of psychotherapy was important to participants and was associated with starting psychotherapy. High importance ratings for the data were primarily driven by the data increasing hopefulness for successful treatment outcomes. Although this study was exploratory, it suggests that explicit presentation of the effectiveness of psychotherapy may create positive expectancies for treatment among older adults.

Therapist effectiveness: implications for accountability and patient care

Significant therapist variability has been demonstrated in both psychotherapy outcomes and process (e.g., the working alliance). In an attempt to provide prevalence estimates of "effective" and "harmful" therapists, the outcomes of 6960 patients seen by 696 therapists in the context of naturalistic treatment were analyzed across multiple symptom and functioning domains. Therapists were defined based on whether their average client reliably improved, worsened, or neither improved nor worsened. Results varied by domain with the widespread pervasiveness of unclassifiable/ineffective and harmful therapists ranging from 33 to 65%. Harmful therapists demonstrated large, negative treatment effect sizes (d= -0.91 to -1.49) while effective therapists demonstrated large, positive treatment effect sizes (d=1.00 to 1.52). Therapist domain-specific effectiveness correlated poorly across domains, suggesting that therapist competencies may be domain or disorder specific, rather than reflecting a core attribute or underlying therapeutic skill construct. Public policy and clinical implications of these findings are discussed, including the importance of integrating benchmarked outcome measurement into both routine care and training.

A randomized controlled pilot study of a brief web-based mindfulness training

BACKGROUND

Mindfulness has been shown to be effective in treating various medical and mental problems. Especially its incorporation in cognitive-behavioural interventions has improved long-term outcomes of those treatments. It has also been shown, that brief mindfulness-based trainings are effective in reducing distress. There have been few web-based interventions incorporating mindfulness techniques in their manual and it remains unclear whether a brief web-based mindfulness intervention is feasible.

METHODS

Out of 50 adults (different distress levels; exclusion criteria: <18 years, indication of psychotic or suicidal ideation in screening) who were recruited via e-mail and screened online, 49 were randomized into an immediate 2-weeks-treatment group (N=28) or a waitlist-control group (N=21), starting with a 2-week delay. Distress (BSI), perceived stress (PSQ), mindfulness (FMI), as well as mood and emotion regulation (PANAS/SEK-27) were measured at pre-, post- and 3-month follow-up (3MFU). Intention-to-treat analyses using MI for missing data and per-protocol analyses (≥50% attendance) were performed.

RESULTS

26 participants of the treatment group completed post-measures. Most measures under ITT-analysis revealed no significant improvement for the treatment group, but trends with medium effect sizes for PSQ (d=0.46) and PANASneg (d=0.50) and a small, non-significant effect for FMI (d=0.29). Per-protocol analyses for persons who participated over 50% of the time revealed significant treatment effects for PSQ (d=0.72) and PANASneg (d=0.77). Comparing higher distressed participants with lower distressed participants, highly distressed participants seemed to profit more of the training in terms of distress reduction (GSI, d=0.85). Real change (RCI) occurred for PSQ in the treatment condition (OR=9). Results also suggest that participants continued to benefit from the training at 3MFU.

CONCLUSION

This study of a brief web-based mindfulness training indicates that mindfulness can be taught online and may improve distress, perceived stress and negative affect for regular users. Although there were no significant improvements, but trends, for most measures under ITT, feasibility of such a program was demonstrated and also that persons continued to use techniques of the training in daily life.

Outcome expectancy as a predictor of treatment response in cognitive behavioral therapy for public speaking fears within social anxiety disorder

Outcome expectancy, the extent that clients anticipate benefiting from therapy, is theorized to be an important predictor of treatment response for cognitive-behavioral therapy. However, there is a relatively small body of empirical research on outcome expectancy and the treatment of social anxiety disorder. This literature, which has examined the association mostly in group-based interventions, has yielded mixed findings. The current study sought to further evaluate the effect of outcome expectancy as a predictor of treatment response for public-speaking fears across both individual virtual reality and group-based cognitive-behavioral therapies. The findings supported outcome expectancy as a predictor of the rate of change in public-speaking anxiety during both individual virtual reality exposure therapy and group cognitive-behavioral therapy. Furthermore, there was no evidence to suggest that the impact of outcome expectancy differed across virtual reality or group treatments.

Illness perception in bulimia nervosa

The study was designed to extend our understanding of illness perceptions in patients with bulimia nervosa (BN). Seventy-eight participants with BN or BN-type Eating Disorder Not Otherwise Specified (EDNOS-BN) completed the Revised Illness Perception Questionnaire (IPQ-R) ( Moss-Morris et al., 2002 ). Clinical variables were also assessed. Participants experienced their ED as chronic, with serious consequences and high associated levels of anxiety and depression. The disorder was attributed primarily to psychological causes. The results indicate the perceived severity of BN, and high level of associated distress. These findings highlight the potential for targeting illness perceptions in treatment.

Outcomes of psychotherapy from the perspective of the users

Psychotherapy is widely held to be an effective means to decrease depression. It seems, however, that not everyone benefits from every kind of therapy, and the relevant outcomes vary from person to person. In this article, the pre-therapy views and post-therapy experiences of 14 users of either long-term psychodynamic psychotherapy or short-term solution-focused therapy are analyzed. The interviewees' personal views about their depression and therapy are approached with the concept of inner narrative. Three "basic stories" or orientations were found: life historical, situational and moral. These offered people different contexts from which to evaluate the outcomes of their therapy. The findings suggest that a person's expectations, hopes and values are worth taking into account to ensure positive therapy outcomes.

The role of treatment expectancy in youth receiving exposure-based CBT for obsessive compulsive disorder

The purpose of this investigation was to examine correlates of parent, child, and therapist treatment expectations and their role in the exposure-based treatment of childhood obsessive compulsive disorder (OCD). Treatment expectations were assessed among 49 youth with primary OCD, their parents, and therapists as part of the baseline evaluation and post-treatment clinical outcomes were determined by blind evaluators. Baseline depressive symptoms, child/parent-rated functional impairment, externalizing behavior problems, number of comorbid psychiatric disorders, and a lower perception of control were associated with lower pre-treatment expectations. Parent expectation was associated with parental OCD symptoms, child depressive symptoms and child-reported impairment. Therapist expectations inversely correlated with child depressive symptoms, externalizing problems, and child-rated impairment. Pre-treatment OCD severity and prior treatment history were not linked to expectancy. Finally, higher treatment expectations were linked to better treatment response, lower attrition, better homework compliance, and reduced impairment.

Pre-Treatment Expectations in Clients: Impact on Retention and Effectiveness in Outpatient Substance Abuse Treatment

Background: Common factors are important for the therapy outcome and also mediate the specific factors of therapy. As one of the common factors, client's expectations towards treatment have been understudied. Aims: The aim was to examine the pre-treatment expectations of outpatient substance abuse treatment clients (N = 327, 111 females, 216 males) and its impact on retention, effectiveness and satisfaction at 6-month follow-up. Method: Dependent variables included the clients’ attitudes towards the twelve-step principles and participation, medical treatment and therapists’ role. Results: An emphasis on the importance of medical treatment at baseline predicted dropping out. Similarly, it predicted a lower percent days abstinent (PDA6) at 6 months follow-up in comparison to those who did not consider medical treatment important for recovery. Percent days abstinent increased with a more positive attitude to mutual support. At follow-up, those who had assessed the therapist's role in recovery to be most important at the baseline were most satisfied with the treatment. Conclusions: The client's pre-treatment expectations have an impact on treatment retention and effectiveness. Further effort should be made to study how clients’ image of treatment could be improved and also how the commitment of the clients with multiple problems could be improved.

Predictors of treatment outcome in modular cognitive therapy for obsessive-compulsive disorder

BACKGROUND

The present study sought to identify predictors of outcome for a comprehensive cognitive therapy (CT) developed for patients with obsessive-compulsive disorder (OCD).

METHODS

Treatment was delivered over 22 sessions and included standard CT methods, as well as specific strategies designed for subtypes of OCD including religious, sexual, and other obsessions. This study of 39 participants assigned to CT examined predictors of outcomes assessed on the Yale-Brown Obsessive Compulsive Scale. A variety of baseline symptom variables were examined as well as treatment expectancy and motivation.

RESULTS

Findings indicated that participants who perceived themselves as having more severe OCD at baseline remained in treatment but more severe symptoms were marginally associated with worse outcome for those who completed therapy. Depressed and anxious mood did not predict post-test outcome, but more Axis I comorbid diagnoses (mainly major depression and anxiety disorders), predicted more improvement, as did the presence of sexual (but not religious) OCD symptoms, and stronger motivation (but not expectancy). A small rebound in OCD symptoms at 1-year follow-up was significantly predicted by higher scores on personality traits, especially for schizotypal (but not obsessive-compulsive personality) traits.

CONCLUSIONS

Longer treatment may be needed for those with more severe symptoms at the outset. CT may have positive effects not only on OCD symptoms but also on comorbid depressive and anxious disorders and associated underlying core beliefs. Findings are discussed in light of study limitations and research on other predictors.

Expectations

Patients' expectations have long been considered a contributory factor to successful psychotherapy. Expectations come in different guises, with outcome expectations centered on prognostic beliefs about the consequences of engaging in treatment. In this article, we define outcome expectations and present assessment methods and clinical examples of outcome expectations. Our research review includes a comprehensive meta-analysis (N =8,016 patients across 46 independent samples) of the association between pretherapy or early-therapy outcome expectations and posttreatment outcomes. The overall weighted effect size was d=.24, p<.001, indicating a small but significant positive effect of outcome expectations on adaptive treatment outcomes. We also provide a narrative review of mediators of the expectation-outcome link and patient factors that relate to their outcome expectations. Finally, we discuss limitations of the research base and offer therapeutic practices based on our findings.

The relationship between therapist and client hope with therapy outcomes

The current study examined whether clients' perceptions of hope and therapists' hope in their clients were associated with therapy outcomes. The authors conducted a naturalistic study of brief therapy with 10 therapists and 43 adult clients. Client-rated hope significantly increased after one session of therapy. However, no significant relationship was found between pretherapy client-rated hope and first-session symptom change. Further, client-rated hope at any point in therapy was not significantly related to therapy outcomes. Therapists' hope in their clients after the first and last sessions was significantly related to client outcomes. Implications for therapy practice and research are offered.

Therapeutic alliance mediates the effect of patient expectancy in dynamic psychotherapy

OBJECTIVES. Patient expectancy has been regarded as an important predictor of psychotherapy outcome, for more than half a century. In recent years, some evidence has emerged indicating that the therapeutic alliance may mediate the association between expectancy and outcome. DESIGN. In this dismantling, randomized clinical study, 100 out-patients who sought psychotherapy due to depression, anxiety, and personality disorders, were assigned to 1 year of dynamic psychotherapy with and without transference interpretation. METHODS. Patients' pre-treatment target expectancies and global expectancy were measured in this clinical trial. Tests of mediation were performed with two patient-rated and one therapist-rated measure of the therapeutic alliance, using regression analyses. Six putative moderators of the mediational paths were explored. RESULTS. Global Optimism was significantly associated with two clinician-rated outcome measures - the Psychodynamic Functioning Scales and Global Assessment of Functioning. Both patient ratings, but not the therapist rating of alliance mediated the association between global expectancy and clinician-rated outcome. None of the putative moderators had a significant effect. CONCLUSION. The results, together with previous findings, indicate that the expectancy-alliance-outcome mediational chain is a general phenomenon, not limited to subgroups of patients or modes of treatment.

Development and psychometric evaluation of the Milwaukee Psychotherapy Expectations Questionnaire

The Milwaukee Psychotherapy Expectations Questionnaire (MPEQ) was developed to measure clients' expectations about the components and effects of therapy. Items were generated rationally based upon the theoretical literature and existing expectancy measures. An exploratory factor analysis revealed a 2-factor solution, comprised of Process Expectations and Outcome Expectations, which was supported by confirmatory factor analyses in three additional samples. The measure demonstrated good internal consistency and test-retest reliability, along with support for convergent, discriminant, and predictive validity. These results present initial evidence for the utility of the MPEQ in assessing both process and outcome expectations in therapy.

The future and promise of cognitive behavioral therapy: a commentary

The Academy for Psychological Clinical Science and the independent accrediting entity it created, the Psychological Clinical Science Accreditation system, have recently launched a movement aimed at reforming all of clinical psychology. If this movement is successful, it will result in a greater emphasis on empirical science in the practice of clinical psychology. As cognitive behavioral therapy (CBT) is the approach that currently has the greatest number of controlled scientific studies supporting it, this should be an impetus for CBT to grow. The very same scientific evidence that supports the efficacy of CBT, however, also shows that CBT is far from fully efficacious. Several recent trends that hold great promise to enhance the effectiveness of CBT are discussed, such as greater integration of CBT with biological approaches, cognitive science, systemic approaches, motivational interviewing, and strengths-based approaches.

Expectancy/Credibility Change as a Mediator of Cognitive Behavioral Therapy for Generalized Anxiety Disorder: Mechanism of Action or Proxy for Symptom Change?

Examined the mediating effect of changes in expectancy/credibility from sessions 4-7 of 14-session cognitive and behavioral therapy for generalized anxiety disorder (GAD). In 76 adults with primary GAD, we predicted that expectancy/credibility would change significantly from sessions 4-7, that degree of change in expectancy/credibility would predict degree of reliable change at posttreatment, and that changes in expectancy/credibility would mediate the relationship between pretreatment severity and change at posttreatment. In support of the hypotheses, a latent growth model revealed significant increases in expectancy/credibility over the critical period. In addition, baseline GAD severity, expectancy/credibility intercept, and rate of change in expectancy/credibility all positively predicted degree of reliable change at posttreatment. Rate of change in expectancy/credibility during the critical period partially mediated the effect of baseline GAD severity, accounting for 38% of the variance in this relationship. This effect was not accounted for by preceding or concurrently changing anxiety levels.

Treatment expectations and preferences as predictors of outcome of acupuncture for chronic back pain

STUDY DESIGN

Preplanned secondary analysis of data from participants receiving acupuncture in a randomized clinical trial.

OBJECTIVE

To determine whether patients' expectations of and preferences for acupuncture predict short and long-term treatment outcomes for persons with chronic back pain.

SUMMARY OF BACKGROUND DATA

Although accumulating evidence suggests that patient expectations and treatment preferences may predict treatment outcomes, few studies have examined this relationship for acupuncture.

METHODS

Four hundred seventy-seven acupuncture-naïve participants with chronic low back pain who were randomized to 1 of 3 acupuncture or simulated acupuncture treatments were the focus of this analysis. Ten treatments were provided during a 7-week period, and participants were masked to treatment assignment. Before randomization, participants provided expectations regarding treatment success, impressions, and knowledge about acupuncture and treatment preferences. Outcomes of interest were functional status (Roland score) and symptom bothersomeness at 8 and 52 weeks postrandomization, obtained by telephone interviewers masked to treatment assignment.

RESULTS

Persons with high pretreatment expectations for the success of acupuncture were more likely to report greater general expectations for improvement, a preference for acupuncture, having heard acupuncture was a very effective treatment and having a very or moderately positive impression of acupuncture. However, none of these variables was a significant predictor of improvement in back-related symptoms or function at 8 or 52 weeks. After 1 treatment, participants' revised expectations of treatment success were only associated with back-symptoms at the end of treatment. After 5 treatments, revised expectation of success was predictive of both symptoms and function at 8 and 52 weeks.

CONCLUSION

Pretreatment expectations and preferences for acupuncture were not found predictive of treatment outcomes for patients with chronic back pain. These results differ from previous studies evaluating acupuncture for chronic back pain. These inconsistent results suggest that the relationship between expectations and outcomes may be more complex than previously believed.

Hypnosis in the treatment of depression: considerations in research design and methods

Depressive disorders constitute a serious problem in the United States and around the world. The appearance of practice guidelines and lists of evidenced-based therapies suggests that adequate treatments for depression exist. However, a careful consideration of what is known and not known about the treatment of depression leaves plenty of room for improved approaches to addressing this condition. Although there has been a dearth of research on the treatment of depression using hypnosis, there are several compelling arguments for the inclusion of hypnotic approaches in the array of current strategies for dealing with depression. However, traditional "gold-standard" research methods, namely randomized controlled trials, have many shortcomings for identifying the potential impact of hypnosis on depression. Other strategies, notably single-case design and benchmarking approaches, may offer a more practical solution to the problem of determining "what works for depression."
