Improving Exposure Therapy: Rationale and Design of an International Consortium

The Exposure Therapy Consortium (ETC) was established to advance the science and practice of exposure therapy. To encourage participation from researchers and clinicians, this article describes the organizational structure and activities of the ETC. Initial research working group experiences and a proof-of-principle study underscore the potential of team science and larger-scale collaborative research in this area. Clinical working groups have begun to identify opportunities to enhance access to helpful resources for implementing exposure therapy effectively. This article discusses directions for expanding the consortium's activities and its impact on a global scale.

A Novel Intervention to Reduce Fear of Progression and Trauma Symptoms in Advanced Cancer Using Written Exposure to Worst-Case Scenarios

Background: Adults with advanced cancer experience profound future uncertainty, reflected in elevated fear of cancer progression (FoP) and cancer-related trauma symptoms. These symptoms are associated with physical symptom burden and poorer quality of life, and few interventions exist to manage them. Objective: To develop and pilot a written exposure-based coping intervention (EASE) focused on worst-case scenarios among adults with advanced cancer reporting elevated cancer-related trauma symptoms or FoP. Design: A single-arm intervention development and pilot trial. Participants: The trial enrolled 29 U.S. adults with stage III or stage IV solid tumor cancer (n = 24) or incurable or higher-risk blood cancer (n = 5) reporting elevated cancer-related trauma symptoms or FoP. Among those screened, 74% were eligible, with an eligible-to-enrolled rate of 85%. Design/Measurements: EASE was delivered over five 1:1 videoconferencing sessions. Feasibility and acceptability were evaluated via attendance, surveys, and exit interviews. Outcomes were assessed at five time points through 3-month (FU1, main assessment of interest) and 4.5-month (FU2) follow-up. Results: Participant and interventionist feedback was used to iteratively refine EASE. Among participants, 86% (25/29) completed all five sessions and FU1; surveys and exit interviews indicated high acceptability. Primary outcomes of cancer-related trauma symptoms and FoP improved significantly from pre to both follow-ups by predominantly large effect sizes. Secondary outcomes of anxiety, depression, hopelessness, fear of death/dying, and fatigue, and most process measures improved significantly by FU1 or FU2. Conclusions: EASE, a novel adaptation of written exposure therapy, is a promising approach to reducing FoP and cancer-related trauma symptoms among adults with advanced cancer that warrants further study.

Values- versus monetary reward-enhanced exposure therapy for the treatment of social anxiety in emerging adulthood

Exposure therapy represents the gold-standard treatment for social anxiety, yet evidence indicates the need for improvement. One promising avenue involves linking exposures to a motivator. The current study examined the impact of intrinsically-rewarding, personal values-enhanced versus extrinsically-rewarding, monetary-enhanced exposure on short-term social anxiety fear and avoidance outcomes, and evaluated impacted initial treatment motivation and exposure generalization.

METHODS

Sixty emerging adults ages 17-26 with significantly elevated social and public speaking anxiety were randomized to receive values-enhanced exposure, monetary reward-enhanced exposure, or exposure alone. They completed a laboratory session with a brief intervention and speech exposure, one-week follow-up with novel exposure, and online follow-up two weeks later. Subjective and behavioral anxiety measures were collected.

RESULTS

Linking exposures to values decreased self-reported anxiety following the speech exposure retest, which generalized to anticipatory anxiety prior to a novel speech task. Linking exposures to money temporarily increased speech length, but this difference did not remain during the novel task. Conditions showed similar improvements on other outcomes.

CONCLUSION

Extrinsic motivators can temporarily motivate exposure engagement, whereas a brief values intervention can enhance exposure learning and decrease subjective anxiety across feared situations compared to monetary enhancement. If replicated, this has pragmatic implications for exposure framing within social anxiety treatment.

Anxiety and Depression in Metastatic Cancer: A Critical Review of Negative Impacts on Advance Care Planning and End-of-Life Decision Making With Practical Recommendations

PURPOSE

Providers treating adults with advanced cancer increasingly seek to engage patients and surrogates in advance care planning (ACP) and end-of-life (EOL) decision making; however, anxiety and depression may interfere with engagement. The intersection of these two key phenomena is examined among patients with metastatic cancer and their surrogates: the need to prepare for and engage in ACP and EOL decision making and the high prevalence of anxiety and depression.

METHODS

Using a critical review framework, we examine the specific ways that anxiety and depression are likely to affect both ACP and EOL decision making.

RESULTS

The review indicates that depression is associated with reduced compliance with treatment recommendations, and high anxiety may result in avoidance of difficult discussions involved in ACP and EOL decision making. Depression and anxiety are associated with increased decisional regret in the context of cancer treatment decision making, as well as a preference for passive (not active) decision making in an intensive care unit setting. Anxiety about death in patients with advanced cancer is associated with lower rates of completion of an advance directive or discussion of EOL wishes with the oncologist. Patients with advanced cancer and elevated anxiety report higher discordance between wanted versus received life-sustaining treatments, less trust in their physicians, and less comprehension of the information communicated by their physicians.

CONCLUSION

Anxiety and depression are commonly elevated among adults with advanced cancer and health care surrogates, and can result in less engagement and satisfaction with ACP, cancer treatment, and EOL decisions. We offer practical strategies and sample scripts for oncology care providers to use to reduce the effects of anxiety and depression in these contexts.

Acceptance and Commitment Therapy Processes and Mediation: Challenges and How to Address Them

Acceptance and commitment therapy (ACT) emphasizes a focus on theory-driven processes and mediating variables, a laudable approach. The implementation of this approach would be advanced by addressing five challenges, including (a) distinguishing ACT processes in measurement contexts, (b) developing and rigorously validating measures of ACT processes, (c) the wide use of psychometrically weaker ACT process measures and the more limited use of stronger measures in earlier work, (d) the inconsistency of past evidence that ACT processes are sensitive or specific to ACT or mediate ACT outcomes specifically, and (e) improving statistical power and transparency. Drawing on the existing literature, we characterize and provide evidence for each of these challenges. We then offer detailed recommendations for how to address each challenge in ongoing and future work. Given ACT's core focus on theorized processes, improving the measurement and evaluation of these processes would significantly advance the field's understanding of ACT.

Pilot randomized trial of an acceptance-based telehealth intervention for women with ovarian cancer and PARP inhibitor-related fatigue

OBJECTIVE

Poly(ADP-ribose) polymerase inhibitors (PARPi) have dramatically changed treatment for advanced ovarian cancer, but nearly half of patients experience significant fatigue. We conducted a two-site pilot randomized trial to evaluate the feasibility, acceptability, and preliminary efficacy of a brief, acceptance-based telehealth intervention (REVITALIZE) designed to reduce fatigue interference in patients on PARPi.

METHODS

From June 2021 to April 2022, 44 participants were randomized 1:1 to REVITALIZE (6 weekly one-on-one sessions+booster) or enhanced usual care. Feasibility was defined as: ≥50% approach-to-consent among potentially eligible patients and ≥70% completion of 12-week follow-up assessment; acceptance was <20% participants reporting burden and <20% study withdrawal. Fatigue, anxiety, depression, and quality of life were assessed at baseline, 4-, 8- and 12-weeks.

RESULTS

Among 44 participants (mean age = 62.5 years, 81.8% stage III/IV disease), the study was feasible (56.4% approach-to-consent ratio, 86.3% completion of 12-week assessment) and acceptable (0% reporting burden, 11.3% study withdrawal). At 12-week follow-up, REVITALIZE significantly reduced fatigue interference (Cohen's d = 0.94, p = .008) and fatigue severity (d = 0.54, p = .049), and improved fatigue levels (d = 0.62, p = .04) relative to enhanced usual care. REVITALIZE also showed promise for improved fatigue self-efficacy, fatigue catastrophizing, anxiety, depression, and quality of life (ds = 0.60-0.86, p ≥ .05). Compared with enhanced usual care, REVITALIZE participants had fewer PARPi dose reductions (6.7% vs. 19.0%), and dose delays (6.7% vs. 23.8%).

CONCLUSIONS

Among fatigued adults with ovarian cancer on PARPi, a brief, acceptance-based telehealth intervention was feasible, acceptable, and demonstrated preliminary efficacy in improving fatigue interference, severity, and levels. REVITALIZE is a novel, scalable telehealth intervention worthy of further investigation.

A pilot randomized study of a telephone-based cognitive-behavioral stress-management intervention to reduce distress in phase 1 oncology trial caregivers

OBJECTIVES

Caregivers of adult phase 1 oncology trial patients experience high levels of distress and face barriers to in-person supportive care. The Phase 1 Caregiver LifeLine (P1CaLL) pilot study assessed the feasibility, acceptability, and general impact of an individual telephone-based cognitive behavioral stress-management (CBSM) intervention for caregivers of phase I oncology trial patients.

METHODS

The pilot study involved 4 weekly adapted CBSM sessions followed by participant randomization to 4 weekly cognitive behavioral therapy sessions or metta-meditation sessions. A mixed-methods design used quantitative data from 23 caregivers and qualitative data from 5 caregivers to examine the feasibility and acceptability outcomes. Feasibility was determined using recruitment, retention, and assessment completion rates. Acceptability was assessed with self-reported satisfaction with program content and participation barriers. Baseline to post-intervention changes in caregiver distress and other psychosocial outcomes were assessed for the 8-session intervention.

RESULTS

The enrollment rate was 45.3%, which demonstrated limited feasibility based on an a priori criterion enrollment rate of 50%. Participants completed an average of 4.9 sessions, with 9/25 (36%) completing all sessions and an 84% assessment completion rate. Intervention acceptability was high, and participants found the sessions helpful in managing stress related to the phase 1 oncology trial patient experience. Participants showed reductions in worry and isolation and stress.

SIGNIFICANCE OF RESULTS

The P1CaLL study demonstrated adequate acceptability and limited feasibility and provided data on the general impact of the intervention on caregiver distress and other psychosocial outcomes. Caregivers of phase 1 oncology trial patients would benefit from supportive care services; a telephone-based intervention may have more utilization and thus make a larger impact.

A Systematic Review and Meta-Analysis of Interventions to Promote Adjuvant Endocrine Therapy Adherence Among Breast Cancer Survivors

PURPOSE

Adjuvant endocrine therapy (AET) adherence among breast cancer survivors is often suboptimal, leading to higher cancer recurrence and mortality. Intervention studies to promote AET adherence have burgeoned, more than doubling in number since this literature was last reviewed. The current aim is to provide an up-to-date systematic review and meta-analysis of interventions to enhance AET adherence and to identify strengths and limitations of existing interventions to inform future research and clinical care.

METHODS

Systematic searches were conducted in three electronic databases. Studies were included in the systematic review if they examined an intervention for promoting AET adherence among breast cancer survivors. Studies were further included in the meta-analyses if they examined a measure of AET adherence (defined as compliance or persistence beyond initiation) and reported (or provided upon request) sufficient information to calculate an effect size.

RESULTS

Of 5,045 unique records, 33 unique studies representing 375,951 women met inclusion criteria for the systematic review. Interventions that educated patients about how to manage side effects generally failed to improve AET adherence, whereas policy changes that lowered AET costs consistently improved adherence. Medication reminders, communication, and psychological/coping strategies showed varied efficacy. Of the 33 studies that met the inclusion criteria for the systematic review, 25 studies representing 367,873 women met inclusion criteria for the meta-analysis. The meta-analysis showed statistically significant effects of the adherence interventions overall relative to study-specified control conditions (number of studies [k] = 25; odds ratio, 1.412; 95% CI, 1.183 to 1.682; P = .0001). Subgroup analyses showed that there were no statistically significant differences in effect sizes by study design (randomized controlled trial v other), publication year, directionality of the intervention (unidirectional v bidirectional contact), or intervention type.

CONCLUSION

To our knowledge, this is the first known meta-analysis to demonstrate a significant effect for interventions to promote AET adherence. The systematic review revealed that lowering medication costs and a subgroup of psychosocial and reminder interventions showed the most promise, informing future research, policy, and clinical directions.

Brain mediators of biased social learning of self-perception in social anxiety disorder

Social anxiety disorder (SAD) is characterized by an excessive fear of social evaluation and a persistently negative view of the self. Here we test the hypothesis that negative biases in brain responses and in social learning of self-related information contribute to the negative self-image and low self-esteem characteristic of SAD. Adult participants diagnosed with social anxiety (N = 21) and matched controls (N = 23) rated their performance and received social feedback following a stressful public speaking task. We investigated how positive versus negative social feedback altered self-evaluation and state self-esteem and used functional Magnetic Resonance Imaging (fMRI) to characterize brain responses to positive versus negative feedback. Compared to controls, participants with SAD updated their self-evaluation and state self-esteem significantly more based on negative compared to positive social feedback. Responses in the frontoparietal network correlated with and mirrored these behavioral effects, with greater responses to positive than negative feedback in non-anxious controls but not in participants with SAD. Responses to social feedback in the anterior insula and other areas mediated the effects of negative versus positive feedback on changes in self-evaluation. In non-anxious participants, frontoparietal brain areas may contribute to a positive social learning bias. In SAD, frontoparietal areas are less recruited overall and less attuned to positive feedback, possibly reflecting differences in attention allocation and cognitive regulation. More negatively biased brain responses and social learning could contribute to maintaining a negative self-image in SAD and other internalizing disorders, thereby offering important new targets for interventions.

Telemedicine-based inspiratory muscle training and walking promotion with lung cancer survivors following curative intent therapy: a parallel-group pilot randomized trial

PURPOSE

Following curative-intent therapy of lung cancer, many survivors experience dyspnea and physical inactivity. We investigated the feasibility, acceptability, safety, and potential efficacy of inspiratory muscle training (IMT) and walking promotion to disrupt a postulated "dyspnea-inactivity" spiral.

METHODS

Between January and December 2022, we recruited lung cancer survivors from Kaiser Permanente Colorado who completed curative-intent therapy within 1-6 months into a phase-IIb, parallel-group, pilot randomized trial (1:1 allocation). The 12-week intervention, delivered via telemedicine, consisted of exercise training (IMT + walking), education, and behavior change support. Control participants received educational materials on general exercise. We determined feasibility a priori: enrollment of ≥ 20% eligible patients, ≥ 75% retention, study measure completion, and adherence. We assessed acceptability using the Telemedicine-Satisfaction-and-Usefulness-Questionnaire and safety events that included emergency department visits or hospitalizations. Patient-centered outcome measures (PCOMs) included dyspnea (University-of-California-San-Diego-Shortness-of-Breath-Questionnaire), physical activity (activPAL™ steps/day), functional exercise capacity (mobile-based-six-minute-walk-test), and health-related quality of life (HRQL, St.-George's-Respiratory-Questionnaire). We used linear mixed-effects models to assess potential efficacy.

RESULTS

We screened 751 patients, identified 124 eligible, and consented 31 (25%) participants. Among 28 participants randomized (14/group), 22 (11/group) completed the study (79% retention). Intervention participants returned > 90% of self-reported activity logs, completed > 90% of PCOMs, and attended > 90% of tele-visits; 75% of participants performed IMT at the recommended dose. Participants had high satisfaction with tele-visits and found the intervention useful. There was no statistically significant difference in safety events between groups. Compared to control participants from baseline to follow-up, intervention participants had statistically significant and clinically meaningful improved HRQL (SGRQ total, symptom, and impact scores) (standardized effect size: -1.03 to -1.30).

CONCLUSIONS

Among lung cancer survivors following curative-intent therapy, telemedicine-based IMT + walking was feasible, acceptable, safe, and had potential to disrupt the "dyspnea-inactivity" spiral. Future efficacy/effectiveness trials are warranted and should incorporate IMT and walking promotion to improve HRQL.

Network intervention analysis of anxiety-related outcomes and processes of acceptance and commitment therapy (ACT) for anxious cancer survivors

OBJECTIVE

Psychotherapies like Acceptance and Commitment Therapy (ACT) are thought to target multiple clinical outcomes by intervening on multiple mechanistic process variables. However, the standard mediation approach does not readily model the potentially complex associations among multiple processes and outcomes. The current study is one of the first to apply network intervention analysis to examine the putative change processes of a psychotherapy.

METHODS

Using data from a randomized trial of ACT versus minimally-enhanced usual care for anxious cancer survivors, we computed pre-to post-intervention (n = 113) residualized change scores on anxiety-related outcomes (general anxiety symptoms, cancer-related trauma symptoms, and fear of cancer recurrence) and putative processes of the intervention (experiential avoidance, self-compassion, and emotional approach coping). We estimated a network model with intervention condition and residualized change scores as nodes.

RESULTS

Contrary to the expectation that intervention effects would pass indirectly to outcomes via processes, network analysis indicated that two anxiety-related outcomes of the trial may have acted as primary mechanisms of the intervention on other outcome and process variables.

CONCLUSIONS

Network intervention analysis facilitated flexible evaluation of ACT's change processes, and offers a new way to test whether change occurs as theorized in psychotherapies.

Psychological flexibility in older adulthood: a scoping review

OBJECTIVES

Psychological flexibility/inflexibility (PF/PI) is a core component of the acceptance and commitment therapy (ACT) model, which is gaining more attention in the geropsychological literature. This scoping review examines the size and scope of the research on PF/PI in older adulthood related to age differences between older adult and younger samples, correlates relevant to psychological health, and changes with ACT.

METHODS

A systematic literature search was conducted using PubMed, CINAHL, and PsycINFO. Peer-reviewed articles available in English were included that: had a mean age ≥65 and a minimum age ≥60; and reported self-report measures of PF/PI. We categorized PF/PI into three domains: open, aware, and engaged.

RESULTS

Forty-six articles were included. Most studies measured open or aware domains; few measured the engaged domain. Older adults evidenced greater awareness compared to younger adults (9 of 13 analyses were significant). Openness and awareness consistently yielded medium to large correlations with anxiety and depression. PF/PI did not relate with positive affect and inconsistently correlated with quality of life measures.

CONCLUSION

Despite emerging trends, variability and limitations were evident in the literature. Specifically, measurement issues, lack of conceptual clarity, and the omission of values and behavioral measures require future attention.

Anxiety trajectories among cancer survivors during the COVID-19 pandemic

PURPOSE

To describe trajectories of general and bodily vigilance anxiety among cancer survivors during COVID-19 and examine associated factors.

DESIGN

Longitudinal survey study (May-December 2020).

SAMPLE

Colorado-based cancer survivors (N = 147).

METHODS

Latent class growth analyses were used to examine trajectories for two types of anxiety (general and body vigilance), and to evaluate associations with fear of cancer recurrence (FCR), loneliness, and emotional approach coping.

FINDINGS

Anxiety levels remained stable over time. Most participants were best characterized by the mild general anxiety and moderate bodily vigilance anxiety classes. FCR predicted both general and bodily vigilance anxiety class, and loneliness distinguished between mild and moderate bodily vigilance anxiety classes.

CONCLUSIONS

Current cancer survivors experienced mild general anxiety and moderate body vigilance anxiety during the early pandemic with no detectable improvement over time, and FCR consistently predicted anxiety outcomes.

IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS

These findings provide insight into the anxiety profiles of cancer survivors during COVID-19 and possible therapeutic targets.

Cancer survivors' cancellations of healthcare appointments during the COVID-19 pandemic: Associations with anxiety and depression

OBJECTIVE

Though it is well-documented that cancer survivors experienced healthcare delays during the COVID-19 pandemic, who initiated those delays has not been examined. This longitudinal study distinguishes rates of patient-from provider-cancelled healthcare appointments at three timepoints during the pandemic, and examines psychosocial factors associated with patient-cancelled appointments.

METHODS

Cancer survivors (N = 147) in the United States completed psychosocial and health behavior measures three times between May and December 2020. We examined rates of patient- and provider-cancelled healthcare appointments, including cancer screening appointments, at each timepoint and change between timepoints. Logistic regression was used to determine if anxiety symptoms, depression symptoms, and COVID-19 fears were associated with self-cancelled healthcare appointments.

RESULTS

In May 2020, one third (33.79%) of participants reported one or more self-cancelled appointments within the prior 2 months and nearly half (45.89%) reported one or more provider-cancelled appointments. Rates of provider-cancelled appointments decreased to 35.71% in June/July 2020 and to 9.24% in November/December 2020 (both reflected p < 0.05 reductions compared to the previous timepoint). Rates of self-cancelled appointments, however, remained more stable (ps > 0.144). In June/July and November/December 2020, higher depression and anxiety symptoms, but not COVID-19 fears, were associated with greater likelihood of self-cancelled appointments.

CONCLUSIONS

Cancer survivors cancelled their healthcare appointments at a stable rate even as provider-cancelled appointments declined. Depression and anxiety symptoms, but not COVID-19 concerns, were associated with patient cancellations. Interventions that address anxiety and depression symptoms may help to promote adherence to cancer survivorship care during the pandemic.

A randomized controlled trial of a multi-modal palliative care intervention to promote advance care planning and psychological well-being among adults with advanced cancer: study protocol

Background

Up to half of adults with advanced cancer report anxiety or depression symptoms, which can cause avoidance of future planning. We present a study protocol for an innovative, remotely-delivered, acceptance-based, multi-modal palliative care intervention that addresses advance care planning (ACP) and unmet psychological needs commonly experienced by adults with metastatic cancer.

Methods

A two-armed, prospective randomized controlled trial (RCT) randomizes 240 adults with Stage IV (and select Stage III) solid tumor cancer who report moderate to high anxiety or depression symptoms to either the multi-modal intervention or usual care. The intervention comprises five weekly two-hour group sessions (plus a booster session one month later) delivered via video conferencing, with online self-paced modules and check-ins completed between the group sessions. Intervention content is based on Acceptance and Commitment Therapy (ACT), an acceptance, mindfulness, and values-based model. Participants are recruited from a network of community cancer care clinics, with group sessions led by the network’s oncology clinical social workers. Participants are assessed at baseline, mid-intervention, post-intervention, and 2-month follow-up. The primary outcome is ACP completion; secondary outcomes include anxiety and depression symptoms, fear of dying, and sense of life meaning. Relationships between anxiety/depression symptoms and ACP will be evaluated cross-sectionally and longitudinally and theory-based putative mediators will be examined.

Discussion

Among adults with advanced cancer in community oncology settings, this RCT will provide evidence regarding the efficacy of the group ACT intervention on ACP and psychosocial outcomes as well as examine the relationship between ACP and anxiety/ depression symptoms. This trial aims to advance palliative care science and inform clinical practice.

A mixed-methods study of the technical feasibility and patient acceptability of a real-time adherence monitor in breast cancer survivors taking adjuvant endocrine therapy

PURPOSE

Oral anti-cancer medications are increasingly common and endocrine therapies represent the most common oral anti-cancer medications in breast cancer. Adjuvant endocrine therapies reduce the likelihood of recurrence and mortality in the approximately 80% of women diagnosed with hormone-receptor-positive breast cancer, thus rendering adherence essential. Real-time medication adherence monitors, such as the Wisepill electronic pillbox, transmit adherence data remotely, allowing for early intervention for non-adherence. However, their feasibility and acceptability have yet to be examined among breast cancer survivors taking endocrine therapies.

METHODS

This study presents quantitative patient-report and technical support data and qualitative patient acceptability data on Wisepill, a common real-time adherence monitor, among 88 breast cancer survivors prescribed adjuvant endocrine therapy.

RESULTS

This mixed-methods study of a common real-time adherence monitor, among the first in breast cancer survivors taking adjuvant endocrine therapy, demonstrates its technical feasibility and patient acceptability.

CONCLUSION

The use of wireless medication monitors that transmit real-time adherence data is uniquely promising for maximizing the benefits of adjuvant endocrine therapy by allowing for continuous tracking, ongoing communication with oncologic or research teams, and early intervention. This study demonstrates the feasibility and patient acceptability of one such real-time adherence monitor.

Randomized Controlled Pilot Trial of a Low-Touch Remotely-Delivered Values Intervention to Promote Adherence to Adjuvant Endocrine Therapy Among Breast Cancer Survivors

BACKGROUND

Oral anti-cancer treatments such as adjuvant endocrine therapies (AET) for breast cancer survivors are commonly used but adherence is a challenge. Few low-touch, scalable interventions exist to increase ET adherence.

PURPOSE

To evaluate the acceptability, feasibility, and initial efficacy of a low-touch, remotely-delivered values plus AET education intervention (REACH) to promote AET adherence.

METHODS

A mixed-methods trial randomized 88 breast cancer survivors 1:1 to REACH or Education alone. Wisepill real-time electronic adherence monitoring tracked monthly AET adherence during a 1-month baseline through 6-month follow-up (FU) (primary outcome). Patient-reported outcomes were evaluated through 3- and 6-month FU (secondary). Multiple indices of intervention feasibility and acceptability were evaluated. Qualitative exit interviews (n = 38) further assessed participants' perceptions of feasibility/acceptability and recommendations for intervention adaptation.

RESULTS

The trial showed strong feasibility and acceptability, with an eligible-to-enrolled rate of 85%, 100% completion of the main intervention sessions, and "good" intervention satisfaction ratings on average. For Wisepill-assessed AET adherence, REACH outperformed Education for Month 1 of FU (p = .027) and not thereafter. Participants in REACH maintained high adherence until Month 4 of FU, whereas in Education, adherence declined significantly in Month 1. Conditions did not differ in self-reported adherence, positive affective attitudes, future intentions, or necessity beliefs. REACH trended toward less negative AET attitudes than Education at 3-month FU (p = .057) reflecting improvement in REACH (p = .004) but not Education (p = .809). Exploratory moderator analyses showed that average to highly positive baseline AET affective attitudes and oncologist-patient communication each predicted higher adherence following REACH than Education; low levels did not. Participants identified recommendations to strengthen the interventions.

CONCLUSIONS

REACH, a low-touch values intervention, showed good feasibility and acceptability, and initial promise in improving objectively-assessed AET adherence among breast cancer survivors (relative to education alone). Future research should target improving REACH's tailoring and endurance.

Evaluating the efficacy of common humanity-enhanced exposure for socially anxious young adults

Despite some evidence of the benefits of self-compassion training among socially anxious individuals, little is known about whether enhancing self-compassion prior to exposure therapy increases initial exposure engagement. Additionally, manipulations have relied on broad definitions of self-compassion, rendering it difficult to distinguish the impact of individual components. This study employed three experiential exercises designed to enhance one facet of self-compassion-common humanity. Socially anxious undergraduates (N = 63) were randomized in groups to 1) common humanity-enhanced exposure (n = 32) or 2) exposure alone (n = 31). In the common humanity condition, participants wrote self-compassionately, shared fears, and completed a common humanity-focused lovingkindness meditation. All participants then completed a speech exposure in front of live judges followed by an optional second exposure. Within the common humanity condition, positive self-responding to the speech exposure increased (b = 0.30, p = .026). Common humanity participants also remained in the first exposure longer, relative to exposure alone (b = -30.92, p = .002). Participants rated exercises as at least moderately helpful, with sharing fears rated most helpful. In sum, a brief group-based multi-modal common humanity induction represents a promising approach to improving initial engagement with feared contexts among socially anxious individuals.

Examining the effects of prior Acceptance and Commitment Therapy (ACT) treatment among anxious cancer survivors during the COVID-19 pandemic: Evidence from a randomized controlled trial

Introduction

The COVID-19 pandemic has presented population-wide novel stressors. Acceptance and Commitment Therapy (ACT) may be potent for coping with novel, unpredictable stressors, but it is unknown whether pre-pandemic ACT treatment conferred protective benefit during the COVID-19 pandemic.

Methods

Participants (N = 73) from a previous randomized controlled trial of ACT (seven 2-h group sessions) versus minimally-enhanced usual care (MEUC) for anxious cancer survivors completed measures of anxiety symptoms, fear of cancer recurrence, and emotional approach coping during the trial and again during the pandemic in May, June/July, and November 2020, an average of 2.71 years after completing ACT or MEUC. We estimated hierarchical linear models to test overall and conditional differences over the trial timepoints, in the interval between the trial and May 2020, and between the pandemic timepoints.

Results

Compared to MEUC, ACT led to greater improvement on the outcomes during the 8-month trial follow-up, consistent with the main trial findings. Across the entire sample, anxiety symptoms and emotional approach coping worsened from the final trial assessment timepoint to May 2020 (ps < .001). During this period, ACT participants worsened significantly more on emotional approach coping (p = .035) than MEUC participants. No significant condition differences emerged at later pandemic timepoints.

Conclusions

Treatment with ACT several years earlier did not provide protective benefit to anxious cancer survivors during the pandemic, relative to MEUC. ACT interventions may need to be targeted to pandemic-specific stressors, or booster sessions may be required for prior ACT treatment completers when faced with novel stressors.

A Randomized Trial of Brief Online Interventions to Facilitate Treatment Seeking for Social Anxiety

This study developed and evaluated a brief, single-session online intervention designed to facilitate treatment seeking among adults with clinically significant social anxiety (SA) symptoms, who generally seek treatment at exceptionally low rates. Adults (N = 267) reporting significant SA symptoms were recruited online and randomized to a brief, single-session online intervention: Education consisted of brief psychoeducation and treatment resources, or Education+Motivation which added treatment seeking-focused motivational content adapted from Motivational Interviewing and Acceptance and Commitment Therapy. Attitudes, intentions, perceived control, and treatment seeking were assessed at Pre, Post, and 1-month follow-up (FU). Both interventions were feasible (90% completion) and improved all outcomes. At FU, 70% reported engaging in one or more SA treatment-seeking behaviors. Education+Motivation was more effective than Education at improving treatment-seeking attitudes and behaviors. A brief online intervention with educational and motivational content is a promising direction for promoting treatment seeking for adults with SA symptoms.

Randomized trial of acceptance and commitment therapy for anxious cancer survivors in community clinics: Outcomes and moderators

OBJECTIVE

Anxiety symptoms are common among cancer survivors. This study evaluated whether an acceptance-based group intervention delivered by social workers in community oncology clinics improved anxiety and related symptoms, and healthcare use, relative to enhanced usual care (EUC).

METHOD

This multi-site trial included 135 survivors of various cancers with moderate to high anxiety about cancer/survivorship, 1.5-24 months after treatment. Participants were randomized 1:1 to a 7-session acceptance and commitment therapy (ACT)-based group (Valued Living) or EUC (access to onsite supportive care plus resource list). Questionnaires were administered at baseline, 1, 2, 5, and 8 months post-randomization, diagnostic interviews at baseline, 2, and 8 months, and healthcare use tracked throughout. Outcomes included anxiety symptoms (primary), related symptoms, and healthcare use. Putative moderators included age, anxiety, and avoidance.

RESULTS

In intent-to-treat comparisons to EUC, Valued Living (VL) showed a nonsignificant pattern of greater improvement on anxiety symptoms (p = .08), improved significantly more on cancer-related post-traumatic stress (p = .002), fear of recurrence (p = .003), and energy/fatigue (p = .02), and missed significantly fewer medical appointments (p < .05). Conditions improved similarly on depressive symptoms, sense of meaning, and most severe anxiety or depressive disorder. Effects were moderated: VL participants with higher baseline anxiety or avoidance (+1SD) improved more on anxiety, meaning (p_s ≤ .01), and disorder severity (p = .05) than their EUC counterparts.

CONCLUSIONS

An acceptance-based group intervention delivered in community oncology clinics enhanced psychological recovery and energy levels, and reduced missed medical appointments for anxious cancer survivors, with stronger effects for more distressed participants.

Cancer survivors' perceived vulnerability to COVID-19 and impacts on cognitive, affective, and behavioral responses to the pandemic

STUDY OBJECTIVES

Given the uncertainty COVID-19 has caused for individuals with prior medical conditions, we examined the extent to which cancer survivors consider themselves at risk for the global COVID-19 pandemic (henceforth COVID), both in general and due to their cancer history. Additionally, we evaluated whether perceived vulnerability to COVID among cancer survivors predicts their cognitive/affective and behavioral responses to the pandemic.

DESIGN/SAMPLE

Cancer survivors who completed primary cancer treatment (median months since treatment = 33.00) and were enrolled in prior behavioral trials with our research team (N = 146) completed two surveys in May-July 2020 (95.89% retention).

METHODS

Participants rated perceived next-year risk of infection and of dying from COVID. We adapted established scales to assess perceived vulnerability to COVID generally versus as a cancer survivor, catastrophizing about possible COVID symptoms, COVID-related contamination fears, and adherence to COVID prevention behaviors.

FINDINGS

In May 2020, on a 1-100 scale with 0 = no chance and 100 = definitely will occur, cancer survivors reported a chance in the next year of contracting COVID of M = 39.94 (SD = 23.90), and dying from COVID of M = 24.46 (SD = 24.84). Cancer survivors reported somewhat greater vulnerability to COVID compared to same-aged peers, increased contamination fears, and high adherence to COVID prevention measures. Similar findings emerged six weeks later, suggesting stability over time. In simple linear regression models, both general and cancer survivor-specific perceived COVID vulnerability predicted COVID symptom catastrophizing and contamination fears; in multivariable models, only general vulnerability remained a significant predictor. General perceived vulnerability and contamination fears predicted greater adherence to COVID prevention behaviors.

CONCLUSIONS

Cancer survivors perceived elevated vulnerability to COVID even years after treatment, which predicted adherence to COVID prevention behaviors. Future research should identify the optimal balance between supporting cancer survivors' concerns and minimizing negative impacts on quality of life.
