Can Optimism, Pessimism, Hope, Treatment Credibility and Treatment Expectancy Be Distinguished in Patients Undergoing Total Hip and Total Knee Arthroplasty?

Evaluation of the Structural and Construct Validity of the Credibility and Expectancy Scale for Patients With Musculoskeletal Disorders

Background The Credibility Expectancy Questionnaire (CEQ) includes three items each on the credibility and expectancy subscales. Credibility indicates to what extent the treatment is reasonable, and expectancy indicates to what extent the treatment is expected to be effective. The CEQ has been assumed to have a two-factor structure: credibility and expectancy, among patients receiving psychotherapy. However, its internal structure has been unknown to patients receiving physical therapy for musculoskeletal disorders. This study aimed to explore the internal structure of the CEQ and preliminary investigate the construct validity of the CEQ among patients receiving physical therapy for musculoskeletal disorders. Methodology A multi-center prospective cohort study was conducted. Data from 100 patients receiving outpatient physical therapy for musculoskeletal disorders was collected using an anonymous paper-based survey. The initial survey was conducted immediately before the initial physical therapy session, and the second survey was conducted after the third to seventh physical therapy sessions. The Patient Specific Functional Scale 2.0 (PSFS 2.0) was collected in both surveys, and the CEQ and an 11-point global rating of change scale (GRCS) were collected in the second survey. Exploratory factor analysis was conducted for the CEQ, and internal consistency was assessed for each subscale and an identified factor structure. Convergent validity in construct validity was also assessed with the hypothesis that Pearson's r values of each CEQ factor score to the PSFS 2.0 change scores and GRCS would range from 0.4 to 0.6. Results An exploratory factor analysis revealed a one-factor structure, where the percentage of the variance for the extraction sums of squared loadings was 62.8%. Cronbach's alpha was 0.89 for all items, 0.91 for the credibility subscale, and 0.75 for the expectancy subscale. Hypothesized correlations to the PSFS 2.0 change score and GRCS were detected with the CEQ total score (r = 0.48 for the PSFS 2.0 change score and r = 0.59 for the GRCS) and each subscale score (credibility subscale, r = 0.48 for the PSFS 2.0 change score and r = 0.49 for the GRCS; and expectancy subscale, r = 0.43 for the PSFS 2.0 change score and r = 0.62 for the GRCS). Conclusion A single-factor internal structure of the CEQ was detected among patients receiving physical therapy for musculoskeletal disorders. Additionally, preliminary evidence of construct validity was detected with convergent validity between the CEQ and functional and perceived improvement.

Linking Patient-Reported Outcome Measure Scores to Adverse Event Data to Gain Insight into Overestimation of Postoperative Patient-Reported Outcome Measure Improvement After Total Hip Arthroplasty and Total Knee Arthroplasty Due to Selective Nonresponse

BACKGROUND

The purpose of the study was to gain insight into how clinically relevant improvement in patient-reported outcome measure scores after total hip arthroplasty (THA) and total knee arthroplasty (TKA) may be underestimated or overestimated, we compared patient-reported outcome measure respondents and nonrespondents on their adverse event rates and assessed whether adverse event occurrence was associated with clinically relevant patient-reported outcome measure improvement from those without adverse events.

METHODS

All primary THAs and TKAs performed in 19 Dutch hospitals between January 2017 and December 2019 were included. The hip disability and osteoarthritis outcome score-physical function short form (HOOS-PS) and knee injury and osteoarthritis outcome score-physical function short form (KOOS-PS) were used to assess the physical function after THA and TKA, respectively. Adverse events included 1-year revision, 30-day readmission, 30-day complications, and long (ie, >75th percentile) length of stay. A clinically relevant improvement was defined as at least a 10-point decrease in HOOS-PS and 9 points in KOOS-PS scores. Associations between adverse events and clinically relevant HOOS-PS and KOOS-PS improvement were assessed using binary logistic regression models adjusted for patient characteristics and clustering of patients within hospitals.

RESULTS

There were 20,338 THA and 18,082 TKA procedures included. Adverse events occurred more frequently in HOOS-PS and KOOS-PS nonrespondents than in respondents. The THA patients experiencing revision, complications, or long length of stay were less likely to experience clinically relevant HOOS-PS improvements (odds ratios of 0.11 [0.06 to 0.20], 0.44 [0.30 to 0.63], and 0.66 [0.50 to 0.88], respectively). The TKA patients experiencing revision or long length of stay were less likely to experience clinically relevant KOOS-PS improvements (odds ratios of 0.26 [0.12 to 0.55] and 0.63 [0.50 to 0.80], respectively).

CONCLUSIONS

Clinically relevant HOOS-PS and KOOS-PS improvements are likely overestimated, as nonrespondents had higher adverse event rates which were associated with lower likelihood to achieve clinically relevant HOOS-PS and KOOS-PS improvements.

Wrist-ankle acupuncture for primary dysmenorrhea: a randomized controlled trial evaluating the efficacy of an analgesic strap

Background

Drawing on the principles of wrist-ankle acupuncture (WAA), our research team has developed a portable device for WAA point compression, termed the acupressure wrist-ankle strap (AWA). The current study aims to evaluate the efficacy of the AWA in alleviating pain associated with primary dysmenorrhea.

Methods

A single-blind, randomized clinical trial was conducted from April 1, 2019, to December 31, 2019. 78 participants with primary dysmenorrhea were recruited from Shanghai University of Traditional Chinese Medicine. All participants were treated on the first day of menstruation for 30 min. Participants in the AWA group used the AWA, the internal side of which is equipped with a tip compression component, while participants in the non-acupressure wrist-ankle acupuncture(NAWA)group used the NAWA, with the inside tip pressing parts removed. The main outcome was the difference in visual analogue scale (VAS) score between baseline and 30 minutes after randomization.

Results

A total of 78 participants aged 18 to 30 years were included in the intention-to-treat analyses. The VAS scores (mean [standard deviation]) in the AWA group were significantly lower than those in the NAWA group at each time point of intervention (5 minutes: 95% CI, [-1.27 to -0.68], p < 0.001; 10 minutes: 95% CI, [-2.34 to -1.51], p < 0.001; 30 minutes: 95% CI, [-3.74 to -2.72], p < 0.001). In the AWA group, 16 participants reported "obvious relief" of dysmenorrhea pain while 23 did not; the average onset time of analgesia they reported were (21.50 ± 3.65) min, while no subjects in NAWA group reported obvious pain relief. The pain threshold (mean [standard deviation]) at SP9 of both sides in AWA group decreased significantly after intervention that in NAWA group (Left: 95% CI, [-5.02 to -1.81], p < 0.001; Right: 95% CI, [-7.67 to -4.24], p < 0.001). There was no significant change in the temperature at CV4 in either group (95% CI, [-0.63 to -0.66], p = 0.970).

Conclusion

This trial substantiates our hypothesis that the AWA provides immediate analgesic effects. The AWA represents an effective and safe non-invasive physical therapy option, which patients can self-administer to alleviate abdominal pain.

Association between expectations and clinical outcomes in online v. face-to-face therapy - an individual participant data meta-analysis

BACKGROUND

Online treatments are increasing in number and are currently available for a wide range of clinical problems. To date little is known about the role of treatment expectations and other placebo-like mechanisms in online settings compared to traditional face-to-face treatment. To address this knowledge gap, we analyzed individual participant data from randomized clinical trials that compared online and face-to-face psychological interventions.

METHODS

MEDLINE (Ovid) and PsycINFO (Ovid) were last searched on 2 February 2021. Randomized clinical trials of therapist guided online v. face-to-face psychological interventions for psychiatric or somatic conditions using a randomized controlled design were included. Titles, abstracts, and full texts of studies were independently screened by multiple observers. The Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline was followed. Authors of the matching trials were contacted for individual participant data. Ratings from the Credibility and Expectancy Questionnaire and the primary outcome measure from each trial were used to estimate the association between expectation ratings and treatment outcomes in online v. face-to-face interventions, using a mixed-effects model.

RESULTS

Of 7045 screened studies, 62 full-text articles were retrieved whereof six studies fulfilled the criteria and provided individual participant data (n = 491). Overall, CEQ ratings predicted clinical outcomes (β = 0.27) at end of treatment with no moderating effect of treatment modality (online v. face-to-face).

CONCLUSIONS

Online treatment appears to be equally susceptible to expectancy effects as face-to-face therapy. This furthers our understanding of the importance of placebo-like factors in online treatment and may aid the improvement of healthcare in online settings.

Acceptability, feasibility, and user satisfaction of a virtual reality relaxation intervention in a psychiatric outpatient setting during the COVID-19 pandemic

Background

The COVID-19 pandemic was particularly difficult for individuals with mental disorders. Due to governmental restrictions, face-to-face offers for psychiatric outpatients like therapies, psychoeducational groups or relaxation courses were limited. Virtual reality (VR) might be a new possibility to support these patients by providing them with a home-based relaxation tool.

Objective

The aim of this study was to evaluate the acceptability, feasibility, and user satisfaction of a supportive therapy-accompanying, relaxation VR intervention in psychiatric outpatients during the COVID-19 pandemic in Germany.

Methods

The four-weeks VR intervention consisted of regular watching of relaxing videos in the participants' home environment. Sociodemographics, feasibility (frequency of use, user-friendliness), satisfaction (Client Satisfaction Questionnaire-8), depressive symptoms (Patient Health Questionnaire-9), quality of life (abbreviated World Health Organization Quality of Life assessment), and credibility and expectancy (Credibility Expectancy Questionnaire-8) were measured in an intention-to-treat (ITT) analysis and a per-protocol (PP) analysis of completers.

Results

In total, N = 40 patients participated in the study. Most of the participants in the ITT analysis (n = 30, 75.0%) used the VR device three or 4 weeks. A majority of the N = 29 completers (PP: n = 18, 62.1%) used it all 4 weeks. Most participants used the device two or more times a week (ITT: n = 30, 83.3%; PP: n = 26, 89.7%) and described the user-friendliness as rather or very easy (ITT: n = 33, 91.7%; PP: n = 26, 89.7%). User satisfaction was high (ITT: 19.42, SD = 4.08; PP: M = 20.00, SD = 4.19) and did not correlate with participants' sex or age (all p < 0.05). Depressive symptoms and psychological quality of life improved significantly from pre-to post-intervention (ITT and PP, all p < 0.05). Higher pre-intervention credibility significantly correlated with a better outcome of satisfaction (ITT and PP), depressive symptoms, physical, psychological, and social quality of life (PP; all p < 0.05).

Conclusion

A supportive therapy-accompanying VR relaxation intervention is feasible and acceptable in a psychiatric outpatient setting. Due to the high satisfaction and user-friendliness, VR can be an easy to implement relaxation tool to support psychiatric outpatients.

The impact of treatment preferences: A narrative review

Attending to treatment preferences is an element of person-centred care, reported as beneficial in improving treatment adherence, satisfaction, and outcome, in practice. The results of preference trials were inconsistent in supporting these benefits in intervention evaluation research. Informed by the conceptualisation of treatment preferences positing their indirect impact on outcomes, this narrative review aimed to summarise the evidence on the effects of preferences on enrolment; withdrawal or attrition; engagement, enactment, and satisfaction with treatment; and outcomes. The search yielded 72 studies (57 primary trials and 15 reviews). The results of vote counting indicated that (1) offering participants the opportunity to choose treatment enhances enrolment (reported in 87.5% of studies), and (2) providing treatments that match participants' preferences reduces attrition (48%); enhances engagement (67%), enactment (50%) and satisfaction with (43%) treatment; and improves outcomes (35%). The results are attributed to conceptual and methodological issues including less-than-optimal assessment of treatment preferences, which contributes to ill-identified preferences, accounting for withdrawal, low enactment, and limited satisfaction with treatment. These treatment processes, in turn, mediate the impact of treatment preferences on outcomes. It is important to refine and standardise the methods for assessing preferences and to examine their indirect impact (mediated by treatment processes) on outcomes in future preference trials to validly identify their benefits.

Outcomes as experienced by older patients after hospitalisation: satisfaction, acceptance, frustration and hope-a grounded theory study

Background

outcomes of hospitalisation are often described in quantitative terms. It is unknown how older frail patients describe their own outcomes.

Objective

to discover how older frail persons describe their own hospitalisation outcomes and the meaning of these outcomes for their daily lives.

Design

Constructivist Grounded Theory approach.

Participants

frail older people discharged from hospital.

Methods

Open interviews in the participant’s home. Transcripts were coded inductively according to the Constructivist Grounded Theory approach.

Results

Twenty-four interviews were conducted involving 20 unique participants. Although for some participants hospitalisation was just a ripple, for others, it was a turning point. It could have positive or negative impacts on outcomes, including remaining alive, disease, fatigue/condition, complaints, daily functioning, social activities and intimate relationships, hobbies, living situation and mental well-being. Few participants were completely satisfied, but for many, a discrepancy between expectation and reality existed. Some participants could accept this, others remained hopeful and some were frustrated. Factors associated with these categories were research and treatment options, (un)clarity about the situation, setting the bar too high or pushing boundaries, confidence in physicians, character traits and social factors.

Conclusions

of the persons whose outcomes did not meet their expectations, some were frustrated, others hopeful and others accepted the situation. The following interventions can help patients to accept: clear communication about options and expectations before, during and after hospitalisation; giving room for emotions; help finding social support, encouragement to engage in pleasant activities and find meaning in small things. For some patients, psychological treatment may be needed.

Do patients’ pre-treatment expectations about acupuncture effectiveness predict treatment outcome in patients with chronic low back pain? A secondary analysis of data from a randomised controlled clinical trial

Objective

This secondary analysis of a randomised controlled patient-blinded trial comparing effectiveness and side effect briefings in patients with chronic low back pain (CLBP) investigated the association between patients’ pre-treatment expectations about minimal acupuncture treatment and pain intensity as outcome during and after the end of the treatment.

Methods

Chronic low back pain patients with a pain intensity of at least 4 on a numeric rating scale from 0 to 10 received eight sessions of minimal acupuncture treatment over 4 weeks. The primary outcome was change in pain intensity rated on a Numerical Rating Scale (NRS 0–10) from inclusion visit to treatment session 4 and to the end of the treatment. Patients’ expectations about the effectiveness of acupuncture were assessed using the Expectation for Treatment Scale (ETS) before randomization. Linear regression was applied to investigate whether patients’ pre-treatment expectations predicted changes in pain intensity during and after treatment.

Results

A total of 142 CLBP patients (40.1 ± 12.5 years; 65.5% female) were included in our analysis. Patients’ pre-treatment expectations about acupuncture treatment were associated with changes in pain intensity after four sessions of minimal acupuncture treatment (b = -0.264, p = 0.002), but not after the end of the treatment. This association was found in females and males.

Conclusions

Our results imply that higher pre-treatment expectations only lead to larger reductions in pain intensity in the initial phase of a treatment, with a similar magnitude for both females and males. As the treatment progresses in the second half of the treatment, adapted expectations or other non-specific effects might play a more important role in predicting treatment outcome.

Assessing preoperative hope and expectations related to functional neurosurgery: a new questionnaire

BACKGROUND

Despite successful functional neurosurgery, patients suffering from epilepsy or Parkinson's disease may experience postoperative psychological distress and social maladjustments. Difficulties in coping with postoperative changes, even positive ones, have shown to be related to patients' presurgery cognitive representations (i.e., expectations, hope). The aim of this study was to develop an instrument assessing various key features of surgery outcomes' representations, namely the Preoperative Hope and Expectations Questionnaire (PHEQ).

METHODS

Participants were patients (n = 50) diagnosed with Parkinson's disease (n = 25) or epilepsy (n = 25), candidates for functional neurosurgery (i.e., Deep brain stimulation, anterior temporal lobectomy). Two to three weeks before the planned surgery, they were administrated items assessing their actual state, preoperative expectations, and hope regarding surgery outcomes. They also completed measures assessing optimism, quality of life and mood.

RESULTS

Exploratory analysis resulted in a 14-item version of the PHEQ composed of two factors (abstract representations, including psychological well-being and concrete representations, such as direct surgery outcomes). The PHEQ demonstrated high internal consistency and good convergent validity. Patients were more prone to express postoperative improvements in terms of hope rather than expectations. They generally focused on concrete rather than abstract features, although patients with Parkinson's disease had higher abstract future-oriented representations.

CONCLUSIONS

The PHEQ presents satisfactory psychometric properties and may be considered as a reliable instrument for research and clinical practice.

Patients' Expectancies to Acupuncture: A Systematic Review

Objective: This systematic review aimed to document and describe how and when to assess patients' expectancies to acupuncture and the relationship between patients' expectancies and clinical effects. Materials and Methods: Three English databases, including PubMed, Cochrane Central Register of Controlled Trials, and EMBASE, and four Chinese databases, including the Chinese Biomedicine Literature Database, Chinese Journal Full-text Database, Chinese Scientific Journal Full-text Database, and Wanfang Database, were searched up to February 2020. Studies involving patients' expectancies to acupuncture were included. Based on the detailed situations of patients' expectancies, we made a standardized data extraction table that included the basic information of articles, study design details, and measurement of expectations. Based on the data, a descriptive analysis was performed, covering the characteristics of studies, measuring methods of expectations and the relationship between patients' expectancies and clinical effects. Methodology quality assessment was also performed by the risk of bias and the standards for reporting interventions in controlled trials of acupuncture. Results: There were 61 randomized controlled trials included in our analysis. The number of articles increased gradually over time and grew significantly after 2008. About half of trials focused on pain alleviation. Expectancies were measured before the treatment (N = 43), after the treatment (N = 3), and both before and after the treatment (N = 10), and five studies did not mention it. The measurement of expectancies used self-made questionnaires or scales (N = 27), the Acupuncture Expectations Scale (N = 6), and other scales (N = 11), while 17 studies did not describe what scale they used. The used questionnaires or scales mostly tried to ascertain the strength of confidence that acupuncture would help. Patients' expectancies and clinical effects were relevant in 19 studies, irrelevant in 21 studies, and were not mentioned in 21 studies. Conclusions: Patients' expectations to acupuncture have received increasing attention in recent years, but there is still no recognized measurement time and methods. It is critical to develop questions and answers regarding patients' expectations with better discrimination and reliability to accurately assess expectations and to explore the relationship between patients' expectations and acupuncture outcomes in future trials.

Acceptability and Feasibility of the Transfer of Face-to-Face Group Therapy to Online Group Chats in a Psychiatric Outpatient Setting During the COVID-19 Pandemic: Longitudinal Observational Study

BACKGROUND

At the height of the COVID-19 pandemic, several mental health care providers were obliged to shut down outpatient services, including group therapy and psychoeducational sessions. The lockdown in many countries is a serious threat to people's mental well-being, especially for individuals with severe mental illnesses. Discontinued outpatient treatments and disruption of daily routines are considered to be risk factors for destabilization of patients with mental illness.

OBJECTIVE

The aim of this study was to evaluate the acceptability, usability, and feasibility of a group chat program to replace cancelled face-to-face group sessions in an outpatient psychiatric department.

METHODS

Participants (N=33) were recruited in the outpatient department of a large university medical center in Leipzig, Germany. Former face-to-face group participants were invited to take part in a therapist-guided group-chat for 4 weeks (8 sessions) and were asked to evaluate the program via self-administered standardized questionnaires at baseline (T0, preintervention), after every chat session (T1), and posttreatment (T2, after 4-6 weeks). The chat groups were specific to the following mental disorder diagnoses and based on the same therapeutic principles and techniques as the former face-to-face groups: anxiety, depression, obsessive-compulsive disorder, and adult attention-deficit/hyperactivity disorder (ADHD). Sociodemographic measures, attitudes toward the COVID-19 pandemic, depressive symptoms (Patient Health Questionnaire-9), quality of life (abbreviated World Health Organization Quality of Life assessment), treatment credibility/expectancy (Credibility Expectancy Questionnaire), and participants' satisfaction (Client Satisfaction Questionnaire-8 [ZUF-8]) were measured.

RESULTS

Participants joined an average of 5 out of 8 offered chat sessions. Participation rates in the respective groups were highest in the ADHD group (8.6/11, 78%) and lowest in the anxiety group (3.7/9, 41%). The overall preintervention level of depressive symptoms was moderate and showed a slight, nonsignificant improvement at posttreatment (T0: mean 10.7, SD 5.5; T2: mean 10.2, SD 5.5). A similar result was observed regarding quality of life (T0: median 41.7-68.8; T2: median 50-70.3). Treatment credibility and expectancy scores were medium-high (T0: meancredibility 18.1, SD 3.8; meanexpectancy 11.2, SD 5.1; T2: meancredibility 17.1, SD 4.8; meanexpectancy 10.3, SD 5.8). Further, significant correlations were detected between posttreatment expectancy score and posttreatment PHQ-9 score (r=-0.41, P=.02), posttreatment physical quality of life (r=0.54, P=.001), and posttreatment psychological quality of life (r=0.53, P=.002). Overall, participants' satisfaction with the program was very high, both after chat sessions and at posttreatment (ZUF-8: mean score 20.6, SD 1.0). Of all participants, a majority (27/31, 87%) rated the program as excellent/good and indicated they would recommend the group chat program to a friend in need of similar help (23/31, 74%).

CONCLUSIONS

A therapist-guided group chat program to substitute outpatient group setting treatment during the COVID-19 lockdown was shown to be feasible, usable, and highly acceptable for participants. Web-based programs such as this one provide an easy-to-implement tool to successfully stabilize participants during a difficult time, such as the COVID-19 pandemic.

Feasibility randomized-controlled trial of online acceptance and commitment therapy for painful peripheral neuropathy in people living with HIV: The OPEN study

BACKGROUND

Neuropathic pain negatively affects quality of life among people living with HIV (PLWH). This study examined the feasibility of conducting a full-scale randomized-controlled trial of online acceptance and commitment therapy ("ACT OPEN") for neuropathic pain in PLWH.

METHODS

Using a parallel-groups design, thirty-eight participants were randomized to ACT OPEN or a waitlist control (2:1). Participants completed standard self-report outcome measures at baseline, and two- and five-months post-randomization. Participants were aware of their allocation, but assessment was blinded.

RESULTS

Twenty-five participants were randomized to ACT OPEN and 13 to the control (of 133 referrals). ACT OPEN completion was 69% and two-month trial retention was 82%. Treatment credibility and satisfaction scores for ACT OPEN were comparable to scores reported in previous trials of cognitive-behavioural treatments for pain. Four adverse events were reported during the study, including one serious adverse event; all of these were unrelated to the research procedures. Small to moderate effects and 95% confidence intervals suggest that the true effect may favour ACT OPEN for improvements in pain intensity/interference and depression.

CONCLUSIONS

A full-scale RCT of online ACT for pain management in PLWH may be feasible with refinements to trial design to facilitate recruitment.

SIGNIFICANCE

Research on pain management in people living with HIV has primarily focused on pharmacological treatments with limited success. This is the first study to show the potential feasibility of a psychological treatment based on acceptance and commitment therapy delivered online and tailored for pain management in people with HIV ("ACT OPEN"). ACT OPEN may be a promising treatment in this population and further evaluation in a full-scale randomized-controlled trial appears warranted.

TRIAL REGISTRATION

The trial was registered (clinicaltrials.gov; NCT03584412).

Recovery expectations of neck pain patients do not predict treatments outcome in manual therapy

Patient recovery expectations can predict treatment outcome. Little is known about the association of patient recovery expectations on treatment outcome in patients with neck pain consulting a manual therapist. This study evaluates the predictive value of recovery expectations in neck pain patients consulting manual therapists in the Netherlands. The primary outcome measure 'recovery' is defined as 'reduction in pain and perceived improvement'. A prospective cohort study a total of 1195 neck pain patients. Patients completed the Patient Expectancies List (PEL) at baseline (3 item questionnaire, score range from 3 to 12), functional status (NDI), the Global Perceived Effect (GPE) for recovery (7-points Likert scale) post treatment and pain scores (NRS) at baseline and post treatment. The relationship between recovery expectancy and recovery (dichotomized GPE scores) was assessed by logistic regression analysis. Patients generally reported high recovery expectations on all three questions of the PEL (mean sumscores ranging from 11.3 to 11.6). When adjusted for covariates the PEL sum-score did not predict recovery (explained variance was 0.10 for the total PEL). Separately, the first question of the PEL showed predictive potential (OR 3.7; 95%CI 0.19-73.74) for recovery, but failed to reach statistical significance. In this study patient recovery expectations did not predict treatment outcome. Variables predicting recovery were recurrence and duration of pain. The precise relationship between patient recovery expectations and outcome is complex and still inconclusive. Research on patient expectancy would benefit from more consistent use of theoretical expectancy and outcome models.

Variables protecting mental health in the Spanish population affected by the COVID-19 pandemic

The pandemic produced by COVID-19 can lead the population to suffer serious psychological disorders. However, there are several psychosocial variables that can enhance resilient outcomes in adverse situations. The aim would be to establish the level of resilience of the general Spanish population exposed to a traumatic situation by the COVID-19 in order to identify which protective factors predict resilient outcomes. 1227 homebound people (863-70.3% women), aged 18-73 years (M = 28.10; SD = 12.88) reported on sociodemographic and psychological variables such as optimism, hope, self-efficacy and post-traumatic growth. Having a higher academic level (β = .47; CI (95%) = .11-.34; p < .01), being autonomous (β = .29; CI (95%) = 0.1-.09; p < .01), along with self-efficacy (β = .42; CI (95%) = .71-92; p < .01) and to a lesser extent optimism (β = .31; CI (95%) = .63-.84; p < .01) would be the predictive variables of a resilient outcome. A high level of statistical power (1-β = 1) and effect size (f2 = 19.2) is observed. The Spanish population exposed to confinement presents high levels of resilience, but no relevant post-traumatic growth has taken place.

Examining Hope as a Transdiagnostic Mechanism of Change Across Anxiety Disorders and CBT Treatment Protocols

Hope is a trait that represents the capacity to identify strategies or pathways to achieve goals and the motivation or agency to effectively pursue those pathways. Hope has been demonstrated to be a robust source of resilience to anxiety and stress and there is limited evidence that, as has been suggested for decades, hope may function as a core process or transdiagnostic mechanism of change in psychotherapy. The current study examined the role of hope in predicting recovery in a clinical trial in which 223 individuals with 1 of 4 anxiety disorders were randomized to transdiagnostic cognitive behavior therapy (CBT), disorder-specific CBT, or a waitlist controlled condition. Effect size results indicated moderate to large intraindividual increases in hope, that changes in hope were consistent across the five CBT treatment protocols, that changes in hope were significantly greater in CBT relative to waitlist, and that changes in hope began early in treatment. Results of growth curve analyses indicated that CBT was a robust predictor of trajectories of change in hope compared to waitlist, and that changes in hope predicted changes in both self-reported and clinician-rated anxiety. Finally, a statistically significant indirect effect was found indicating that the effects of treatment on changes in anxiety were mediated by treatment effects on hope. Together, these results suggest that hope may be a promising transdiagnostic mechanism of change that is relevant across anxiety disorders and treatment protocols.

Characterizing the Use of Expectations in Orthopedic Surgery Research: A Scoping Review

Objective

Orthopedic literature on expectations is limited by lack of uniformity in how expectations are defined, conceptualized, and measured. Within this scoping review, we present a conceptual framework for understanding the construct of expectations and its derivatives (ie, expectation, expectancy, expectancies, etc) in studies of elective surgical orthopedic procedures. We also utilize this framework to map the current orthopedic surgery literature on expectations, highlighting its strengths, weaknesses, and gaps in its knowledge base.

Methods

We included articles that mentioned both expectations and one or more of 10 selected surgeries in their title or abstract. We focused on representative elective orthopedic surgeries that covered the body's major regions. We operationalized each study's individual expectation items into one of the expectation concept types within the presented conceptual model. We also extracted the name and type of expectations measurement tool used, whose expectations were measured, and descriptive information (eg, surgery type, publication date, country of origin, and study type).

Results

Ninety studies were included, with 70% published after 2008. A total of 64% investigated total knee and total hip arthroplasty, whereas 90% of studies investigated the expectations of patients, 5.6% investigated the expectations of physicians, and 4.4% investigated both. Of all studies, 72% utilized either study‐specific instruments with close‐ended, Likert‐type response formats or modifications of existing expectations questionnaires. Most studies focused on desirable, nontimeline‐related, treatment outcome expectations. Many studies aggregated multiple expectation results into a single score.

Conclusion

Adopting the standardized framework for expectations presented in this study will foster clearer communication and permit researchers to aggregate results across studies.

Assessment of patients' expectations: development and validation of the Expectation for Treatment Scale (ETS)

OBJECTIVE

To develop a short self-report instrument for the assessment of expectations (Expectation for Treatment Scale(ETS)) using acupuncture as a case example.

DESIGN

A cross-sectional assessment with retest after 1 week.

SETTING

A web-based survey with patients suffering from pain.

METHODS

In a three-step approach, we reduced the initially collected number of items from 17 to 9 and to 5, including expectations about coping ability, vitality, physical health and reduction of patient complaints. Items were selected according to internal consistency (Cronbach's alpha); convergent and divergent validities with related constructs (optimism, pessimism, resilience, perceived sensitivity to medicines, depression and others); 1-week retest reliability (intraclass correlation coefficient (ICC)); and exploratory and confirmatory factor analysis (CFA).

RESULTS

A total of 102 patients suffering from pain were included, and 54 of these patients completed the retest assessment. The final version of the ETS consisted of five items and had an excellent Cronbach's alpha (0.90), with 72.33% variance on one single factor. Depression, pessimism and perceived sensitivity to medicines showed positive correlations with our expectation measure (r=0.23, r=0.20 and r=0.34, respectively); the correlation between the ETS and optimism was low (r=-0.07) and no correlation between the ETS and resilience was found (r=-0.07). Convergent validity was confirmed with a high correlation (r>0.90) between ETS and a treatment-specific measure of expectations. The retest ICC was 0.86, which showed high stability over 1 week. A CFA (n=439) with data from patients with low back pain confirmed the single-factor structure of the instrument.

CONCLUSION

The ETS showed strong psychometric properties and covered a distinct construct. As the next step, the ETS might be implemented in different clinical conditions and settings to investigate psychometrics and its predictive power for treatment outcomes.

A Standardized Preoperative Group Intervention Is Feasible and Acceptable to Orthognathic Surgery Patients

PURPOSE

Nearly 10% of patients remain dissatisfied after orthognathic surgery, largely because of psychoeducational or psychosocial factors. The purpose of this study was to evaluate the feasibility and acceptability of a psychoeducationally based group intervention to improve preoperative preparation of orthognathic surgical patients and their caregivers.

MATERIALS AND METHODS

The intervention consisted of 2 group sessions, with each session lasting 2 hours. The sessions provided realistic expectations of the surgery, offered teaching strategies for coping with pre- and postoperative symptoms of psychopathology, and highlighted the importance of social support. Feasibility was based on attendance, homework completion, and data collection rates, and acceptability was based on post-treatment participant satisfaction scores on the Client Satisfaction Questionnaire-8 (CSQ-8) and credibility and expectancy scores on 2 subscales of the Credibility/Expectancy Questionnaire-Modified (CEQ-M).

RESULTS

Twenty-six orthognathic surgical patients were recruited from an outpatient oral and maxillofacial surgery clinic to attend the group-based intervention. Seventy percent of patients who attended at least 1 session completed the 2 sessions, and 64% of those who attended the 2 sessions completed at least 1 homework assignment. The authors successfully collected 84% of the total measures given to patients and their caregivers. The mean satisfaction rating of the patients was 30.12 of 32 (CSQ-8; n = 13; standard deviation [SD], 2.33), the mean credibility rating of the patients and their caregivers was 25.2 of 27 (CEQ-M; n = 20; SD, 1.85), and the mean expectancy rating of the patients and their caregivers was 20.54 of 27 (CEQ-M; n = 20; SD, 4.39).

CONCLUSION

The psychoeducationally based group intervention was feasible and acceptable for participants and their caregivers. This article offers suggestions to further improve the feasibility and acceptability of the intervention, including optimizing standardization of data collection procedures, decreasing barriers to access, and increasing participant engagement.

The development of the Patient Expectations of Shoulder Surgery survey

BACKGROUND

Patient satisfaction after a surgical procedure is dependent on meeting preoperative expectations. There is currently no patient expectations survey available for patients undergoing shoulder surgery that is validated, reliable, and easy to use in daily practice. The aim of this study was to develop a Patient Expectations of Shoulder Surgery (PESS) survey.

METHODS

In 315 patients, answers to an open-ended question about patient expectations were collected before shoulder surgery to develop the PESS survey. Patients' expectations of the PESS survey were associated with clinical outcome (change of Disabilities of the Arm, Shoulder, and Hand score). Content validity was assessed by a panel of 10 patients scheduled for shoulder surgery, and test-retest reliability was evaluated.

RESULTS

Six items were included in the PESS survey: pain relief, improved range of motion, improved ability to perform daily activities, improved ability to perform work, improved ability to participate in recreational activities and sports, and stop shoulder from dislocating. Three of the 6 expectations were significantly associated with clinical outcome after shoulder surgery. Test-retest reliability was high with an intraclass correlation coefficient of 0.52-0.92.

DISCUSSION

The PESS survey is a valid and reliable survey that can be used in future clinical research and in daily orthopedic practice. We believe that the preoperative evaluation of patient expectations should be a standard procedure before shoulder surgery.

GPs' mental wellbeing and psychological resources: a cross-sectional survey

Background

The negative impact of work has been the traditional focus of GP surveys. We know little about GP positive mental health and psychological resources.

Aim

To profile and contextualise GP positive mental health and personal psychological resources.

Design and setting

Cross-sectional survey of GPs working in Northern Ireland (NI).

Method

A questionnaire comprising the Warwick Edinburgh Mental Wellbeing Scale (WEMWBS) and measures of resilience, optimism, self-efficacy, and hope, and sociodemographic information was posted to 400 GPs randomly selected from a publicly available GP register.

Results

The response rate was 55% (n = 221 out of 400). Mean value for GP wellbeing (WEMWBS) was 50.2 (standard deviation [SD] 8) compared to UK vets 48.8 (SD 9), UK teachers 47.2 (SD 9), and the population of NI 50.8 (SD 9). After adjustment for confounding, mean WEMWBS was 2.4 units (95% CI = 0.02 to 4.7) higher in female GPs than males (P = 0.05), and 4.0 units (95% CI = 0.8 to 7.3) higher in GPs ≥55 years than GPs ≤44 years (P = 0.02). Optimism was 1.1 units higher in female GPs than male GPs (95% CI = 0.1 to 2.0), and 1.56 units higher in GPs ≥55 years (95% CI = 0.2 to 2.9) than in those ≤44 years. Hope was 3 units higher in GPs ≥55 years (95% CI = 0.4 to 5.7) than in those aged 45–54 years. Correlation between WEMWBS and psychological resources was highest with hope (r = 0.65, P < 0.001).

Conclusion

GPs have levels of positive mental health that are comparable to the local population and better than other occupational groups, such as vets and teachers. Male and younger GPs may have most to gain from wellbeing interventions.

Patients' Expectations Regarding Medical Treatment: A Critical Review of Concepts and Their Assessment

Patients’ expectations in the context of medical treatment represent a growing area of research, with accumulating evidence suggesting their influence on health outcomes across a variety of medical conditions. However, the aggregation of evidence is complicated due to an inconsistent and disintegrated application of expectation constructs and the heterogeneity of assessment strategies. Therefore, based on current expectation concepts, this critical review provides an integrated model of patients’ expectations in medical treatment. Moreover, we review existing assessment tools in the context of the integrative model of expectations and provide recommendations for improving future assessment. The integrative model includes expectations regarding treatment and patients’ treatment-related behavior. Treatment and behavior outcome expectations can relate to aspects regarding benefits and side effects and can refer to internal (e.g., symptoms) and external outcomes (e.g., reactions of others). Furthermore, timeline, structural and process expectations are important aspects with respect to medical treatment. Additionally, generalized expectations such as generalized self-efficacy or optimism have to be considered. Several instruments assessing different aspects of expectations in medical treatment can be found in the literature. However, many were developed without conceptual standardization and psychometric evaluation. Moreover, they merely assess single aspects of expectations, thus impeding the integration of evidence regarding the differential aspects of expectations. As many instruments assess treatment-specific expectations, they are not comparable between different conditions. To generate a more comprehensive understanding of expectation effects in medical treatments, we recommend that future research should apply standardized, psychometrically evaluated measures, assessing multidimensional aspects of patients’ expectations that are applicable across various medical treatments. In the future, more research is needed on the interrelation of different expectation concepts as well as on factors influencing patients’ expectations of illness and treatment. Considering the importance of patients’ expectations for health outcomes across many medical conditions, an integrated understanding and assessment of such expectations might facilitate interventions aiming to optimize patients’ expectations in order to improve health outcomes.

Specific expectancies are associated with symptomatic outcomes and side effect burden in a trial of chamomile extract for generalized anxiety disorder

OBJECTIVE

Patient expectancies are hypothesized to contribute to the efficacy and side effects of psychiatric treatments, but little research has investigated this hypothesis in the context of psychopharmacological therapies for anxiety. We prospectively investigated whether expectancies predicted efficacy and adverse events in oral therapy for Generalized Anxiety Disorder (GAD), controlling for confounding patient characteristics correlating with outcomes.

METHODS

Expectancies regarding treatment efficacy and side effects were assessed at baseline of an eight week open-label phase of a trial of chamomile for Generalized Anxiety Disorder (GAD). The primary outcome was patient-reported GAD-7 scores, with clinical response and treatment-emergent side-effects as secondary outcomes. Expectancies were used to predict symptomatic and side-effect outcomes.

RESULTS

Very few baseline patient characteristics predicted either type of expectancy. Controlling for a patient's predicted recovery based on their baseline characteristics, higher efficacy expectancies at baseline predicted greater change on the GAD-7 (adjusted β = -0.19, p = 0.011). Efficacy expectancies also predicted a higher likelihood of attaining clinical response (adjusted odds ratio = 1.69, p = 0.002). Patients with higher side effect expectancies reported more side effects (adjusted log expected count = 0.26, p = 0.038). Efficacy expectancies were unrelated to side effect reports (log expected count = -0.05, p = 0.680), and side effect expectancies were unrelated to treatment efficacy (β = 0.08, p = 0.306).

CONCLUSIONS

Patients entering chamomile treatment for GAD with more favorable self-generated expectancies for the treatment experience greater improvement and fewer adverse events. Aligning patient expectancies with treatment selections may optimize outcomes.

Pain expectations in neuropathic pain: Is it best to be optimistic?

BACKGROUND

Pain expectancy may be an important variable that has been found to influence the effectiveness of treatments for pain. Much of the literature supports a self-fulfilment perspective where expectations for pain relief predict the actual pain experienced. However, in conditions such as neuropathic pain (NeP) where pain relief is difficult to attain, expectations for pain relief could be unrealistic. The objective of this study was to investigate the relationship between realistic/unrealistic expectations and 6-month, post-treatment outcomes.

METHODS

We performed a retrospective analysis of a large cohort of patients with NeP (n = 789) attending tertiary care centres to determine the association between unrealistic (both positive and negative) and realistic expectations with outcomes after multidisciplinary treatment. An expectation variable with three categories was calculated: realistic expectations were those whose expected reduction in pain was similar to the observed mean group reduction in pain, while optimistic and pessimistic expectations were those who over- or under-estimated the expected response to treatment, respectively. The association between baseline realistic/unrealistic expectations and 6-month pain-related disability, catastrophizing and psychological distress was assessed.

RESULTS

Univariable analyses suggested that realistic expectations were associated with lower levels of disability, catastrophizing and psychological distress, compared to unrealistic expectations. However, after adjustment for baseline symptom severity, multivariable analysis revealed that patients with optimistic expectations had lower levels of disability, than those with realistic expectations. Those with pessimistic expectations had higher levels of catastrophizing and psychological distress at follow-up.

CONCLUSIONS

These findings are largely congruent with the self-fulfilment perspective to expectations.

SIGNIFICANCE

This study defined realistic pain expectations with patient data. Examining the relationship between expectations between pain and disability in a large cohort of patients with neuropathic pain.

Overlap and Differences Between Patient and Provider Expectations for Treatment Outcomes: The Case of Acupuncture

Our study aimed to identify patient-provider clusters with different patterns of expectations for treatment outcomes. All patients (n = 885) received acupuncture treatment from physicians for their migraine, headache, osteoarthritis, or chronic low back pain. We identified 6 robust patient-provider expectation clusters (PPECs; interclassification reliability >.89) showing differences between patients and providers in their expected treatment responses (eg, unrealistic optimists, optimistic doubters). For example, the optimistic doubters had high expectations for their treatment outcomes but were skeptical of the benefits of acupuncture in general. The providers expected good improvements for these patients. These 6 PPECs differed in their clinical characteristics and in the associated treatment responses. For example, unrealistic optimists showed the weakest treatment benefits after 6 months; other PPECs and clinical patterns are also presented in the report. Our study suggests that comparing the expectations of patients and providers is a valuable approach to identify groups of patients with greater responsiveness and those with limited treatment benefits.

PERSPECTIVE

Patients and providers of acupuncture might vary in their expectation of the treatment effect and in clinical practice the overlap of expectations of patients and providers should be considered as important in initial consultations.
