A retrospective cost-effectiveness analysis of different cognitive-behavioral therapy for insomnia intervention delivery approaches in adult cancer survivors.

BACKGROUND: Cognitive-behavioral therapy for insomnia (CBT-I) is considered the gold standard treatment for insomnia. Prior trials have delivered CBT-I across a range of treatment sessions. Understanding the economics of varying treatment approaches is essential for future implementation considerations. METHODS: We conducted a retrospective cost-effectiveness analysis from the provider's perspective, comparing the implementation of a three-session CBT-I program for cancer survivors (CBT-I-CS) versus a stepped care treatment approach consisting of an initial single sleep education session followed by CBT-I-CS if elevated insomnia symptoms persisted. The effectiveness measure used was the percentage of participants whose insomnia had remitted by the end of each program. RESULTS: Stepped care delivery was more effective than CBT-I-CS alone, resulting in 35.4% more remitted patients by the end of the overall program. For a $480 willingness to pay threshold per percentage of remitted patients, stepped care CBT-I-CS reached a 98% probability of being cost-effective, while CBT-I-CS alone had only a 2% probability. Larger group sessions in the first step of a stepped care delivery model resulted in more favorable cost-effectiveness. CONCLUSIONS: A stepped care delivery model may be a more cost-effective approach if it can be implemented efficiently. These findings inform policies aimed at improving cancer survivors' access to much-needed insomnia treatment in settings where financial resources for CBT-I may be limited, and be an important barrier to treatment dissemination.

Insomnia is a big problem for cancer survivors. Prioritizing evaluation and treatment is essential!

Sleep Treatment Education Program for Young Adult Cancer Survivors (STEP-YA): Protocol for an Efficacy Trial.

BACKGROUND: Young adult cancer survivors (YACS) are at elevated risk for chronic insomnia, even years after completing treatment. In addition to potential health consequences, insomnia can interrupt social, educational, and vocational development just as they are trying to "make up" for time lost to cancer. Cognitive behavioral therapy for insomnia (CBTI) is recommended as first-line treatment for insomnia but remains largely unavailable to YACS due to several barriers (ie, shortage of trained providers, geographic limitations, financial limitations). Traditional CBTI has not been adapted to meet YACS' unique developmental and circadian challenges. To improve availability of effective behavioral insomnia treatment for this population, we developed the Sleep Treatment Education Program for Young Adult Cancer Survivors (STEP-YA), a low-intensity educational intervention delivered virtually online. OBJECTIVE: In this phase 2 "proof of concept" trial, primary aims are to test the efficacy of STEP-YA to improve insomnia symptoms and mood in YACS and assess the utility of individualized coaching to improve treatment effects. A secondary aim will explore participant variables associated with clinically significant response to STEP-YA. METHODS: This 2-arm randomized prospective trial will enroll 74 off-treatment YACS aged 20 years to 39 years with clinically significant insomnia. Each participant completes the STEP-YA intervention in a 1-on-1 synchronous online session led by a trained interventionist following a structured outline. The 90-minute intervention presents educational information on the development of insomnia after cancer and offers specific suggestions for improving insomnia symptoms. During the session, participants review the suggestions and develop a personalized sleep action plan for implementing them. After the session, participants are randomized to either the coaching condition, in which they receive 2 telephone coaching sessions, or the no-coaching condition, which offers no subsequent coaching. The Insomnia Severity Index (ISI) and the Profile of Mood States: Short Form (POMS-SF) are assessed at baseline and 4 and 8 weeks postintervention. RESULTS: Enrollment began in November 2022, with 28 participants currently enrolled. We anticipate recruitment will be completed in 2024. The primary endpoint is a change in ISI score from baseline to 8 weeks postintervention. The secondary endpoint is change in mood symptoms (POMS-SF) from baseline to 8 weeks postintervention. Change scores will be treated as continuous variables. Primary analyses will use ANOVA methods. A within-subjects analysis will examine if the STEP-YA intervention is associated with significant changes in insomnia and mood over time. A 2-way ANOVA will be used to evaluate the utility of coaching sessions to improve treatment effects. CONCLUSIONS: Chronic insomnia has significant negative effects on YACS' medical, educational, and psychological functioning. STEP-YA aims to address their needs; study results will determine if the intervention warrants future effectiveness and dissemination studies and if individualized coaching is necessary for adequate treatment response.

Evaluating SunSmart: a brief educational intervention promoting sun protection in young adult cancer survivors.

PURPOSE: Young adult cancer survivors (YACS) are at risk for secondary skin cancers but relevant interventions have not been validated in this population. To address this, we designed and tested SunSmart, a set of two educational videos designed to promote sun protection (SP). One provides SP education (Information) and the second combines SP education with content on negative appearance consequences of sun exposure (Information + Appearance). METHODS: One hundred ninety-three YACS (aged 18-35) were randomized to one of three groups: (1) Information, (2) Information + Appearance, or (3) control (sleep hygiene video). Participants completed measures on SP behaviors at baseline and follow-up. One-way ANCOVAs examined the intervention effect on follow-up SP behaviors controlling for baseline behaviors. RESULTS: The intervention did not significantly affect SP behaviors. However, secondary analyses limited to participants with the lowest baseline SP adherence found that the Information + Appearance group had significantly lower intentional sun exposure than the control group (p = 0.02) at follow-up. CONCLUSIONS: Contrary to hypotheses, the SunSmart intervention did not significantly improve sun protection in YACS, even when it presented information on negative appearance consequences of sun exposure. However, secondary analyses suggest SunSmart may be more effective in YACS with the lowest SP adherence. Future research is required to improve intervention efficacy with YACS (e.g., increased focus on secondary cancer risks). IMPLICATIONS FOR CANCER SURVIVORS: Despite their increased risk of secondary skin cancer, YACS in the current study reported significant sun exposure and inadequate SP. The need for development and validation of effective interventions to address these concerns remains.

Screening young adult cancer survivors for depression and anxiety with the Primary Care Evaluation of Mental Disorders (PRIME-MD): Comparisons with a structured clinical diagnostic interview.

OBJECTIVE: Survivorship guidelines recommend screening for depression and anxiety in young adult cancer survivors (YACS), but research validating measures in this population is limited. The current study aimed to examine use of the Primary Care Evaluation of Mental Disorders (PRIME-MD) to screen for depression and anxiety in YACS. METHODS: 249 YACS (aged 18-40, 50% male) completed PRIME-MD via Telephone Automated Computer Assisted Structured Interview and the Structured Clinical Interview for the DSM-IV (SCID) via in-person interview. SCID responses were scored to identify depressive and anxiety symptoms and diagnoses. PRIME-MD was scored to identify YACS reaching the symptom threshold (≥1 depressive or anxiety symptom) and diagnostic threshold for depressive or anxiety disorder. ROC analyses evaluated concordance of the PRIME-MD with the SCID. RESULTS: The PRIME-MD depressive symptom threshold had excellent discrimination compared to SCID depressive diagnosis (AUC = 0.83) with high sensitivity (86%) and specificity (81%). Similarly, the PRIME-MD depressive diagnosis threshold had excellent discrimination compared to SCID depressive diagnosis (AUC = 0.86) as well as high sensitivity (86%) and specificity (86%). No PRIME-MD threshold met sensitivity (≥0.85) and specificity (≥0.75) criteria for identifying SCID depressive symptoms, anxiety disorders, or anxiety symptoms. CONCLUSIONS: PRIME-MD has potential utility as a screening measure of depressive disorders in YACS. The PRIME-MD depressive symptom threshold may be particularly useful in survivorship clinics as it requires only two items be administered. However, PRIME-MD does not meet study criteria for a standalone screen for anxiety disorders, anxiety symptoms, or depressive symptoms in YACS.

Evaluating posttraumatic stress in young adult cancer survivors: Implications of revised DSM-5 traumatic event criteria.

OBJECTIVE: The Diagnostic and Statistical Manual for Psychiatric Diagnoses (DSM-5) significantly narrowed conditions under which life-threatening illnesses meet qualifying traumatic event (QTE) criteria for posttraumatic stress disorder (PTSD). To investigate the impact of this change on identification of PTSD in young adult cancer survivors (YACS), we compared prevalence of QTE exposure using DSM-5 and earlier DSM-IV criteria. METHODS: The Structured Clinical Interview for the DSM-5 (SCID-5) was customized for study goals and administered to a convenience sample of 250 YACS ages 18-40 followed at a single cancer center. RESULTS: The SCID-5 was well-tolerated by participants and estimated duration was brief (33 min; range 12-75). Only 35 interviews (14%) presented complex scoring questions. 168 participants (67.2%) identified cancer as their "most stressful or traumatic experience." Applying DSM-IV criteria, 227 YACS (90.8%) reported any QTEs; prevalence was significantly reduced following more restrictive DSM-5 QTE criteria, with only 124 YACS (49.6%) reporting ≥1 QTE (z = -9.68, p < 0.001). CONCLUSIONS: The SCID-5 can be successfully adapted to assess QTEs in YACS following both DSM-IV and DSM-5 criteria. DSM-5 criteria significantly limit prevalence of QTE exposures compared with DSM-IV. As the majority of YACS identify cancer as their most stressful life event, it is critically important to investigate its impact on their psychological functioning. Until more is known about how PTSD symptoms may arise after cancer, clinicians and researchers should adapt PTSD assessments to systematically evaluate the role of cancer as a traumatic event that may lead to PTSD symptoms in YACS.

Evaluating the Sleep Treatment Education Program (STEP-1): A single-session educational workshop addressing insomnia in cancer survivors.

Insomnia is a common late effect of cancer, affecting as many as 27% of cancer survivors. Although cognitive behavioral therapy for insomnia (CBT-I) is highly effective, treatment-associated burdens and limited availability of providers result in few survivors receiving this treatment. To address this gap, we developed the Sleep Treatment Education Program-1 (STEP-1), a single-session intervention addressing insomnia after cancer. As a preliminary evaluation of STEP-1's potential to improve survivors' insomnia, STEP-1 was delivered to a convenience sample of 34 cancer survivors as an educational workshop in person or by videoconference. Participants completed the Insomnia Severity Index (ISI) at the workshop and at 1-month follow-up; items assessing participants' intentions to implement program suggestions and satisfaction were also collected. At 1-month follow-up, mean insomnia symptoms on the ISI were significantly lower compared to baseline (9.73 vs 15.73; d = 1.38, P < .001); the reduction in mean ISI scores did not significantly differ between in-person and videoconference participants (5.82 vs 6.33; P = .78). These results, along with positive indicators of program engagement and satisfaction, support the potential efficacy of STEP-1 to meet survivors' needs for insomnia care. Particularly when delivered by videoconference, STEP-1 has the potential to dramatically improve access and uptake for insomnia treatment in cancer survivors. Results also more generally support development of low-intensity, self-management insomnia interventions for cancer survivors and potentially other populations.

Genome-wide association study of posttraumatic stress disorder among childhood cancer survivors: results from the Childhood Cancer Survivor Study and the St. Jude Lifetime Cohort.

Genetic influence shapes who develops posttraumatic stress disorder (PTSD) after traumatic events. However, the genetic variants identified for PTSD may in fact be associated with traumatic exposures (e.g., interpersonal violence), which appear heritable as well. Childhood cancer survivors (CCS) are at risk for PTSD, but genetic influences affecting cancer are unlikely to overlap with those affecting PTSD. This offers a unique opportunity to identify variants specific to PTSD risk. In a genome-wide association study (GWAS), 3984 5-year survivors of childhood cancer of European-ancestry from the Childhood Cancer Survivor Study (CCSS) were evaluated for discovery and 1467 survivors from the St. Jude Lifetime (SJLIFE) cohort for replication. Childhood cancer-related PTSD symptoms were assessed using the Posttraumatic Stress Diagnostic Scale in CCSS. GWAS was performed in CCSS using logistic regression and lead markers were replicated/meta-analyzed using SJLIFE. Cross-associations of identified loci were examined between CCS and the general population. PTSD criteria were met for 671 participants in CCSS and 161 in SJLIFE. Locus 10q26.3 was significantly associated with PTSD (rs34713356, functionally mapped to ECHS1, P = 1.36 × 10-8, OR 1.57), and was replicated in SJLIFE (P = 0.047, OR 1.37). Variants in locus 6q24.3-q25.1 reached marginal significance (rs9390543, SASH1, P = 3.56 × 10-6, OR 0.75) in CCSS and significance when meta-analyzing with SJLIFE (P = 2.02 × 10-8, OR 0.75). Both loci were exclusively associated with PTSD in CCS rather than PTSD/stress-related disorders in general population (P-for-heterogeneity < 5 × 10-6). Our CCS findings support the role of genetic variation in PTSD development and may provide implications for understanding PTSD heterogeneity.

Evaluating sensitive symptoms in young adult cancer survivors: acceptability of suicidal ideation and sexual health items across administration modes.

PURPOSE: Patient-reported outcomes (PROs) are essential for assessing potential late effects experienced by young adult cancer survivors (YACS), but stigma and social desirability bias may limit their effectiveness for assessing sensitive topics (e.g., suicidal ideation, sexual health). This study compared two methods of item administration to determine the optimal method for obtaining sensitive information in YACS. METHODS: Two hundred forty-four YACS (ages 18-40) were randomized to complete measures of suicidal ideation and sexual health (i.e., sensitive items) by paper survey or by telephone automated computer assisted structured interview (TACASI). Participants also provided information on acceptability of administration mode and sensitive items. RESULTS: The proportion of participants reporting symptoms did not significantly vary between paper and TACASI administration: respectively, 10% vs. 12% reported suicidal ideation and 55% vs. 58% reported sexual health concerns. The majority (≥ 78%) of participants reported feeling comfortable answering sensitive items on paper and TACASI and there were no significant differences in acceptability based on administration mode. Although participants endorsing sensitive symptoms were significantly more likely to feel upset answering sensitive items, the majority (93%) of participants experiencing symptoms still felt they were important to ask. CONCLUSIONS: Despite their potentially sensitive nature, questions about suicidal ideation and sexual health were highly acceptable to YACS across administration modes. Moreover, YACS almost universally endorse the importance of providers asking about these topics. IMPLICATIONS FOR CANCER SURVIVORS: Findings should bolster provider confidence that screening for suicidal ideation and sexual health concerns can and should be integrated into clinical care for YACS using paper or technology-assisted methods.

Recommendations for the surveillance of mental health problems in childhood, adolescent, and young adult cancer survivors: a report from the International Late Effects of Childhood Cancer Guideline Harmonization Group.

Survivors of childhood, adolescent, and young adult (diagnosed when <25 years of age) cancer are at risk of mental health problems. The aim of this clinical practice guideline is to harmonise international recommendations for mental health surveillance in survivors of childhood, adolescent, and young adult cancer. This guideline was developed by a multidisciplinary panel of experts under the sponsorship of the International Guideline Harmonization Group. We evaluated concordance among existing survivorship clinical practice guidelines and conducted a systematic review following evidence-based methods. Of 7249 studies identified, 76 articles from 12 countries met the inclusion criteria. Recommendations were formulated on the basis of identified evidence in combination with clinical considerations. This international clinical practice guideline strongly recommends mental health surveillance for all survivors of childhood, adolescent, and young adult cancers at every follow-up visit and prompt referral to mental health specialists when problems are identified. Overall, the recommendations reflect the necessity of mental health surveillance as part of comprehensive survivor-focused health care.

Validation of the Three-Item Insomnia Severity Index Short Form in Young Adult Cancer Survivors: Comparison with a Structured Diagnostic Interview.

Chronic insomnia affects ∼25% of young adult cancer survivors (YACS) but is often overlooked in routine follow-up. A recently introduced three-item version of the Insomnia Severity Index (ISI-3) was compared with a diagnostic interview (SCID-5) in 250 YACS (ages 18-40) to evaluate its validity in this population. The ISI-3 had good discrimination compared with the SCID-5 (area under the receiver operating characteristic curve = 0.88). Although no ISI-3 cutoff met study criteria for both sensitivity (≥0.85) and specificity (≥0.75), an ISI-3 cutoff of ≥4 had high sensitivity (94%) and moderate specificity (70%), and is recommended as the first step in a two-step screening procedure.

The Effect of Pediatric Cancer on Identity in Young Adult Survivors: Results from Project REACH.

Purpose: Living through cancer can have a profound effect on identity. Among those treated for adult-onset cancer, identifying as a cancer survivor is common and has been linked to positive mental and physical health outcomes. Although childhood is a critical period for identity formation, comparatively less is known about identity development after pediatric cancers. Methods: One hundred seventy young adults previously treated for pediatric cancer enrolled in Project REACH, a prospective cohort study, and completed self-report measures on effect of cancer on identity (e.g., cancer victim and survivor identity), frequency of thoughts of cancer, health outcomes (i.e., anxiety, depression, and health-related quality of life), and health behaviors (i.e., smoking, sun protection, exercise, and binge drinking). Results: The majority of participants identified as a survivor (n = 146, 85.9%), and survivor identity was linked to significantly higher anxiety (p = 0.01) and worse overall mental health (p = 0.04), but no other health outcomes or behaviors. Only 14 participants (8.2%) endorsed the victim identity, and they were significantly more likely to report binge drinking (p = 0.03) and worse overall mental health (p = 0.02) than nonvictims. Frequency of thoughts of cancer and effect of cancer on identity were also significantly associated with health outcomes (e.g., more frequent thoughts associated with higher anxiety). Conclusions: Our findings suggest that what is known about the relationship between identity and health outcomes after adult-onset cancer cannot be generalized to pediatric cancers, and that clinicians should not assume survivor identity is associated with better health outcomes in this group.

Validating the Patient-Reported Outcomes Measurement Information System Short Form v1.0-Anxiety 8a in a sample of young adult cancer survivors: Comparison with a structured clinical diagnostic interview.

BACKGROUND: The objective of this study was to validate the Patient-Reported Outcomes Measurement Information System Short Form v1.0-Anxiety 8a (PROMIS-A-SF) against a structured diagnostic interview in order to determine its accuracy and the most appropriate cutoff score for identifying anxiety disorders in young adult cancer survivors (YACSs). METHODS: Two hundred forty-nine YACSs aged 18 to 40 years (50% male) completed the PROMIS-A-SF and the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID). The SCID was used to determine whether participants met the criteria for an anxiety diagnosis. Receiving operator characteristic analyses were performed to determine the concordance of the PROMIS-A-SF and the SCID as well as cutoff scores with sensitivity (≥0.85) and specificity (≥0.75) appropriate for an anxiety screening measure. RESULTS: The PROMIS-A-SF was determined to have good overall discrimination in comparison with the SCID (area under the curve, 0.84). A PROMIS-A-SF t-score cutoff ≥ 53.2 (total predictive value, 67.9%) came closest to meeting the study criteria with a sensitivity of 88%, but the specificity was only 65%. In a hypothetical screening example, this cutoff led to moderate levels of missed cases (14%) and a significant proportion of clinical referrals that were unnecessary by SCID criteria (35%). Of the survivors referred for services according to these criteria, less than one-third (29%) would have a SCID anxiety diagnosis. CONCLUSIONS: The PROMIS-A-SF demonstrated moderately strong concordance with anxiety disorders measured by the SCID, but cutoff scores did not meet study criteria for clinical screening. Although it may not be appropriate as a standalone screener, the PROMIS-A-SF may be useful for assessing anxiety in YACSs when it is incorporated into clinical practice or when it is combined with other measures.

Providing Effective Mental Health Support for Oncology Health-Care Workers in the COVID-19 Era: Responding Quickly but Carefully.

Oncology health-care workers (HCWs) are facing substantial stressors during the current coronavirus disease 2019 pandemic, resulting in a wide range of acute stress responses. To appropriately meet the growing mental health needs of HCWs, it is imperative to differentiate expectable stress responses from posttraumatic stress disorder and mental illness, because traditional mental health interventions may pathologize healthy stress reactions and risk retraumatizing HCWs under acute duress. Further, HCWs are experiencing protracted forms of acute stress as the pandemic continues, including moral injury, and require mental health interventions that are flexible and can adapt as the acuity of stressors changes. Previously developed frameworks to support people experiencing acute stress, such as Psychological First Aid, are particularly relevant for HCWs in the ongoing pandemic. Acute stress interventions like Psychological First Aid are guided by the Stress Continuum Model, which conceptualizes stress reactions on a continuum, from a zone of normal readiness and expectable consequences to a zone of more persistent and extreme reactions such as posttraumatic stress disorder and major depression. Key principles of the Stress Continuum Model include the expectation that emotional reactivity does not lead to psychiatric problems, that interventions need to be appropriately targeted to symptoms along the stress continuum, and that people will return to normal recovery. Various core actions to reduce acute stress include delivering practical assistance, reducing arousal, mobilizing support, and providing targeted collaborative services. This nonpathologizing approach offers a valuable framework for delivering both individual and organizational-level interventions during the coronavirus disease 2019 pandemic.

Validation of the Insomnia Severity Index (ISI) for identifying insomnia in young adult cancer survivors: comparison with a structured clinical diagnostic interview of the DSM-5 (SCID-5).

OBJECTIVES: Insomnia is a common problem affecting young adult cancer survivors (YACS) even years after treatment, yet it often goes unidentified and untreated. The Insomnia Severity Index is a widely-used insomnia measure, but has not been studied as an insomnia screener for YACS. The goal of this study was to validate the ISI in YACS by determining its utility in identifying YACS with insomnia disorder diagnosed with the Structured Clinical Interview for the DSM-5 (SCID-5). METHODS: 250 YACS completed the ISI and SCID-5 Insomnia Module. Area under the curve (AUC) was calculated to reflect the ISI's discrimination between YACS with and without SCID-5 insomnia disorder. An ISI cut-off score with sensitivity ≥0.85 and specificity ≥0.75 was deemed acceptable. RESULTS: Of 250 participants, 52 met criteria for SCID-5 insomnia disorder diagnosis. The ISI had excellent discrimination, with an AUC = 0.91. A cut-off score ≥8 met study clinical screening criteria with sensitivity of 0.85 and specificity of 0.77. A cut-off score ≥7 with a higher sensitivity (0.96) but lower specificity (0.70) was noted as a potential alternative. Cut-off scores ≥12 and ≥ 14 were recommended for applications prioritizing overall accuracy. CONCLUSIONS: Results support validity of the ISI for identifying YACS with insomnia disorder. For clinical screening, data support the use of an ISI cut-off score ≥8 in YACS, and additional cut-off scores were found for research purposes or higher sensitivity. Results of this study and prior studies of the ISI offer important reminders that cut-off scores derived from different populations are not generalizable.

Virtual visits as long-term follow-up care for childhood cancer survivors: Patient and provider satisfaction during the COVID-19 pandemic.

Telemedicine can potentially meet objectives of long-term follow-up care (LTFU) for childhood cancer survivors (CCS) while reducing barriers. We surveyed providers at our institution about their satisfaction with video-conference virtual visits (VV) with 81 CCS during COVID-19 restrictions. The same 81 CCS (or parent proxies) were surveyed about their experience, of which 47% responded. Providers and CCS were highly satisfied with VV (86% and 95% "completely/very satisfied," respectively). CCS rated VV "as/nearly as" helpful as in-person visits (66%) and 82% prefer VV remain an option postpandemic. High levels of survivor and provider satisfaction with VV support ongoing investigation into implementation for LTFU.

Long-Term Psychosocial Well-Being and Quality of Life Among Childhood Cancer Survivors Who Developed a Subsequent Malignant Neoplasm.

Childhood cancer survivors (CCS) are at increased risk of subsequent malignant neoplasms (SMNs). However, the impact of SMNs on long-term psychosocial functioning is unknown. In a cohort of 322 young adult CCS, survivors who developed a SMN (n = 43, 13.4%) did not report a significantly higher burden of fatigue, insomnia, depression, anxiety, or impaired quality of life on average 8 years after SMN diagnosis. They, however, endorsed significantly greater body image concerns. Our findings indicate that CCS with an SMN do not significantly differ from those without regarding most psychosocial outcomes in young adulthood, although clinicians may be vigilant for greater body image dissatisfaction.

Internet-delivered insomnia intervention improves sleep and quality of life for adolescent and young adult cancer survivors.

BACKGROUND: Insomnia is common among adolescent and young adult (AYA) cancer survivors. Cognitive-behavioral therapy for insomnia (CBT-I) is considered the gold standard treatment. Standard CBT-I was designed for adults and not adapted to the unique medical, psychosocial, and developmental needs of AYA cancer survivors, which can exacerbate their insomnia. Further, the vast majority of cancer centers do not have a behavioral sleep medicine expert on staff. Our study objective was to examine the efficacy of an Internet-delivered CBT-I program that was tailored for AYA cancer survivors (NCT03279055). PROCEDURE: Twenty-two AYA cancer survivors (mean age 20.4; range 14-25) with insomnia enrolled in an automated CBT-I program modified for AYA cancer survivors following stakeholder feedback. Participants were blood cancer (54.5%) and solid tumor (45.5%) survivors, an average of 9.7 years postdiagnosis. Sleep health, fatigue, and quality of life were assessed at baseline and at two follow up timepoints (8 and 16 weeks postbaseline). RESULTS: Significant improvements in insomnia severity, daytime sleepiness, fatigue, and quality of life were reported at both follow up timepoints. However, most participants (72.7%) did not complete all of the six study sessions, with a mean completion rate of 3.2 sessions. Participants who completed at least two sessions reported better sleep (insomnia severity index total score) than those who did not. CONCLUSIONS: An Internet-delivered insomnia intervention adapted for AYA cancer survivors was efficacious. This has important implications for access to evidence-based clinical care for this growing population. Future efforts should study stepped care models of care and ways to improve treatment adherence.
