The Relationship Between Dreams and Subsequent Morning Mood Using Self-Reports and Text Analysis

While material from waking life is often represented in dreams, it is less clear whether and how dreams impact waking life. Here, we assessed whether dream mood and content from home diaries predict subsequent waking mood using both subjective self-reports and an objective automated word detection approach. Subjective ratings of dream and morning mood were highly correlated within participants for both negative and positive valence, suggesting that dream mood persists into waking. Text analyses revealed similar relationships between affect words in dreams and morning mood. Moreover, dreams referencing death or the body were related to worse morning mood, as was first-person singular pronoun usage (e.g., "I"). Dreams referencing leisure or ingestion, or including first-person plural pronouns (e.g., "we"), were related to better morning mood. Together, these results suggest that subjective experiences during sleep, while often overlooked, may be an important contributor to waking mood.

0356 Does Unconscious Socioeconomic Bias Influence Tele-evaluation of Obstructive Sleep Apnea? A Tele-Equity Exploratory Analysis

Introduction

Telemedicine, once of limited scope, has become common and widespread due to the present and ongoing SARS-CoV-2 pandemic. Center to home delivery, the most common model, allows for convenient and efficient care. Concurrent with this groundshift, there is increasing attention to disparities in medical services, and how these disparities may impact patient outcomes. Telemedicine could be used to help bridge barriers to timely quality care, however, patient access and longstanding institutional biases may limit the potential. Healthcare providers must actively develop systems to ensure that telemedicine is optimized for people across the income spectrum. This exploratory analysis examined how economic disparities in patients being evaluated for obstructive sleep apnea may be associated with providers’ clinical impressions. The objective was to study the inter-method reliability of pre-test probability of obstructive sleep apnea assessed via telemedicine and in-person evaluations, and to compare that reliability between income classes.

Methods

This is a secondary analysis of a pre-pandemic interrater reliability study, conducted between March 2017 and January 2019. Our researchers completed a randomized, blinded study comparing the pre-test probability of obstructive sleep apnea between an in-person physician and a separate physician seeing the same patient via televideo conferencing. Patients referred to the University of Rochester (UR) Sleep Center were eligible for the study. Women and men 30-70 years old were invited to participate. The patients were not necessarily referred to the center for evaluation of sleep disordered breathing. Patients with dementia, hearing or visual loss, severe psychiatric or developmental illness, or not fluent in English were excluded. Patients had adequate computer literacy, access to high speed internet, and a computing device with appropriate video camera and microphone.The primary objective of the original study was to assess the interrater reliability between the in-person and telemedicine raters for pre-test probability of sleep apnea (high, moderate, or low). Providers used clinical judgement from the history and examination to determine pre-test probabilityFor this present analysis, we assessed the inter-method reliability separately for strata defined by reported annual income level: low income (< $50,000), middle income ($50,000-$100,000), and high income (> $100,000). Reliability was quantified for each stratum using weighted kappa statistics given the ordinal nature of the outcome variable, pre-test probability of obstructive sleep apnea (high, moderate, or low). Weighted kappa statistics were compared between the income strata (high vs. middle, high vs. low, middle vs. low). The operant statistic assumed an approximate standard normal distribution under the null hypothesis of equal kappa values in the two income strata. The Bonferroni method was used to adjust the p-values for the three pairwise comparisons performed among the three income strata.

Results

Data from 53 patients were avaiable for this analysis. 11 of these patients were in the low income group, 22 in the middle income, and 16 were in the high income group. 9 patients did not include their income bracket, and were not included in the analysis. Inter-method reliabilities, assessed using weighted kappa, were 0.83 (low income), 0.24 (middle income), and 0.66 (high income). When comparing between the strata, the kappa statistics were significantly different (p=0.005) between the low and moderate income groups. There was a trend between the high and moderate income groups that did not meet statistical significance (p=0.07).

Conclusion

The intermethod reliability was substantial in the low income stratum, moderate in the high income stratum, and slight in the middle income group based on the kappa statistic. There was a significant difference in the reliability values of telemedicine versus in-person assessments between the low and middle income brackets, and there was a trend between the high and moderate groups. Since the raters were unaware of the patients’ income levels, this association might suggest possible unconscious bias in evaluating for OSA. It may also suggest that beyond access to telemedicine technology, the quality of the care may also be influenced by socioeconomic factors. With telemedicine in its early stages, it is important to develop this technology that will minimize biases that could result from patients’ economic fortunes.

0671 Nightmare type and its association with suicide attempts among veterans

Introduction

Research has begun to distinguish between idiopathic (no known origin), trauma-related (recurring after a trauma), and complex nightmares (trauma-related nightmares that recur comorbidly with sleep disordered breathing). Nightmare type may impact symptom severity as well as treatment outcomes among various patient groups. Thus, we sought to examine the individual effects of nightmare type on suicide re-attempts and, secondarily, on treatment utilization.

Methods

This is a secondary analysis of electronic medical record data. Data were extracted for all Veterans with a documented suicide attempt (using ICD-10 codes) during FY13-14. A 1:1 case control was then created using age, sex, and prior year behavioral health treatment utilization. The present sample is comprised of all Veterans from that parent dataset who carry an ICD-10 diagnosis of nightmare disorder (n = 3207). Groups were defined as follows: 1) Idiopathic (n = 589; nightmare disorder only); 2) Trauma (n = 3207; nightmare disorder plus ICD-10 diagnosis of PTSD); 3) Complex (n = 576; nightmare disorder + PTSD + ICD-10 diagnosis of a sleep-related breathing disorder).

Results

Multiple logistic regression revealed that only trauma-related nightmares were positively associated with suicide re-attempts (B = 0.16, SE = 0.06, p < 0.01), with an estimated odds ratio of 1.27 (95% CI of 1.02-1.57). Regarding treatment utilization, regression analyses revealed that both complex nightmares (B = 0.36, p < 0.05) and trauma-related nightmares (B = 0.31, p < 0.05) were significantly associated with mental healthcare utilization (total days).

Conclusion

Our results revealed that both complex and trauma-related nightmares are associated with mental health treatment utilization. Only trauma-related nightmares were significantly associated with suicide re-attempts. Trauma-related nightmares may be distressing because of their trauma-related content, therefore making them more likely to predict reattempts. Overall, results suggest that nightmares are positively associated with suicide re-attempts and increased treatment utilization.

0471 Identifying Trauma-Informed Adaptations to Cognitive Behavioral Therapy for Insomnia among Women Veterans: Results of an Expert Panel

Introduction

Trauma-informed care is an emerging area of health services research. While trauma-focused care specifically targets symptoms of posttraumatic stress disorder (PTSD), trauma-informed care involves tailoring interventions to meet the unique needs of patients who have experienced trauma. Insomnia and PTSD are common comorbid disorders, but no known previous studies have identified trauma-informed adaptations to cognitive behavioral therapy for insomnia (CBT-I).

Methods

We identified PTSD clinical presentations that may interfere with the delivery of effective CBT-I and possible adaptations to standard CBT-I that may address these clinical presentations based on a literature review. We then incorporated trauma-informed adaptations into a 5-session CBT-I protocol. Four Veterans Affairs (VA) Expert Trainers in CBT-I were sent the trauma-informed CBT-I materials and rating forms. They were asked to rate the extent to which PTSD clinical presentations serve as barriers to CBT-I (1=low barrier; 5=high barrier), the feasibility of possible adaptations (1=low feasibility; 5=high feasibility), and to provide qualitative feedback. A 60-minute panel meeting was convened and aggregated data from rating forms were presented and discussed. We then revised the trauma-informed CBT-I materials. Panelists reviewed the revised trauma-informed CBT-I materials and completed post-panel rating forms.

Results

The highest-ranked clinical presentations based on rating forms and panel consensus included: sleep avoidance/nighttime arousal, sleep-related self-efficacy, substance/medication use to induce sleep, and safety behaviors intended to reduce nighttime arousal. Panel meeting consensus identified the following trauma-informed adaptations to CBT-I: PTSD-related nighttime hyperarousal psychoeducation, identification of alternatives to PTSD-related safety behaviors, nightmare psychoeducation, psychoeducation about PTSD avoidance in the context of substance/medication use, cognitive techniques, and behavioral tracking to challenge beliefs and avoidant behaviors. Panelists agreed the revised trauma-informed CBT-I materials adequately addressed the PTSD clinical presentations that may limit the effectiveness of standard CBT-I for patients with comorbid PTSD.

Conclusion

This was the first study to use an expert panel to identify trauma-informed adaptations to CBT-I. Trauma-informed adaptations, including supplemental materials, may improve CBT-I outcomes for patients with comorbid PTSD. Future studies should incorporate feedback from patients with insomnia and PTSD to refine trauma-informed adaptations to CBT-I further.

Characteristics of Posttraumatic Nightmares and Their Relationship to PTSD Severity Among Combat Veterans With PTSD and Hazardous Alcohol Use

ABSTRACT

Although nightmares are known to predict the clinical course of posttraumatic stress disorder (PTSD), research on the relationship between specific nightmare characteristics and PTSD severity is sparse. This study conducted a secondary analysis to explore how five nightmare characteristics are cross-sectionally related to PTSD severity in 76 combat veterans with PTSD and at-risk alcohol use. Consistent with emotional processing theory, we hypothesized that more replicative, threatening, realistic, and easily recalled nightmares would be associated with more severe PTSD, whereas those with greater symbolism would predict lower PTSD severity. Nightmares narratives were audio-recorded and rated by multiple coders. Multiple analyses of variance explored the relationship between nightmare characteristics and PTSD clinical indicators. Most nightmares were realistic, easily recalled, and involved significant threat. Greater realism and replication were associated with greater PTSD severity. Realistic and replicative nightmares may be markers of more severe PTSD and may indicate that less emotional processing of the trauma has occurred.

Interrater reliability between in-person and telemedicine evaluations in obstructive sleep apnea

STUDY OBJECTIVES

We examined how telemedicine evaluation compares to face-to-face evaluation in identifying risk for sleep-disordered breathing.

METHODS

This was a randomized interrater reliability study of 90 participants referred to a university sleep center. Participants were evaluated by a clinician investigator seeing the patient in-person, then randomized to a second clinician investigator who performed a patient evaluation online via audio-video conferencing. The primary comparator was pretest probability for obstructive sleep apnea.

RESULTS

The primary outcome comparing pretest probability for obstructive sleep apnea showed a weighted kappa value of 0.414 (standard error 0.090, P = .002), suggesting moderate agreement between the 2 raters. Kappa values of our secondary outcomes varied widely, but the kappa values were lower for physical exam findings compared to historical elements.

CONCLUSIONS

Evaluation for pretest probability for obstructive sleep apnea via telemedicine has a moderate interrater correlation with in-person assessment. A low degree of interrater reliability for physical exam elements suggests telemedicine assessment for obstructive sleep apnea could be hampered by a suboptimal physical exam. Employing standardized scales for obstructive sleep apnea when performing telemedicine evaluations may help with risk-stratification and ultimately lead to more tailored clinical management.

435 Single Session CBT to Improve PAP Initiation and Adherence among Veterans with OSA

Introduction

Obstructive sleep apnea (OSA) is a condition that is prevalent, pernicious, and linked to the development and exacerbation of several disease processes. Positive airway pressure (PAP) is a highly efficacious intervention; however, initiation and adherence rates are poor. This represents a critical gap in care and a missed opportunity to reduce morbidity and mortality associated with OSA. The present study piloted a single session of cognitive behavioral therapy for treatment seeking (CBT-TS) among veterans diagnosed with obstructive sleep apnea and newly prescribed PAP.

Methods

Participants were asked to complete assessments at baseline and at two- and four-weeks post-intervention. A sample of 40 Veterans were enrolled in the study and completed a baseline interview, 27 completed CBT-TS. A matched comparison group of 64 veterans who did not receive the intervention was constructed using electronic medical record and PAP adherence data. Mann Whitney U and Chi Square tests were used to examine group differences in initiation and adherence.

Results

Participants who completed the CBT-TS session were more likely to initiate PAP (at least 3 consecutive nights of use) as compared to those receiving treatment as usual (TAU) [(CBT-TS; 96.3%; 26/27) versus (TAU; 64.1%; 41/64); X2(1, N = 91) = 10.16, p = .001]. Participants in the CBT-TS group also used their PAP devices for a greater number of nights over the first month than the comparison group [(CBT-TS; M = 21.7 (SD = 8.9), Mdn = 26.0) versus (TAU; M = 14.4 (SD = 12.6), Mdn = 15.5); U = 555.0, p = .007] and were more likely to use the device in an adherent manner (i.e., ≥4 hours use in an evening); [(CBT-TS; M = 15.1 (SD = 11.2); Mdn = 15.0) versus (TAU; M = 10.3 (SD = 11.2), Mdn = 6.5); U =630.0, p = .038].

Conclusion

These preliminary data suggest that CBT-TS may have utility in increasing initiation of PAP and subsequent treatment adherence among Veterans diagnosed with OSA and newly prescribed PAP.

502 Idiopathic hypersomnia and co-occurring psychopathology among veterans

Introduction

Idiopathic hypersomnia (IH) is relatively rare and characterized by excessive daytime sleepiness despite prolonged and undisturbed sleep as well as the absence of cataplexy and other causes of hypersomnolence. The etiology of IH is largely unknown. The present study capitalized on electronic medical record (EMR) data from the Veterans Health Administration (VHA) to create a cohort of veterans diagnosed with IH in order to: 1) estimate the prevalence of IH diagnosis in the VHA, and 2) identify co-occurring physical and behavioral health conditions to characterize IH in the sample.

Methods

Using 2009–19 VHA EMR data, we created two cohorts: those with an IH diagnosis (N = 3,674) or a hypersomnia diagnosis (e.g., primary hypersomnia) other than IH (N = 110,530). Diagnostic data (i.e., ICD 9 and 10 codes) were extracted for the 6-months prior to index diagnosis to examine group differences in the prevalence of physical and behavioral health conditions.

Results

Veterans diagnosed with IH, as compared to veterans with another hypersomnia disorder, were more likely to be female (30.1% vs 12.3%) and less likely to be obese (16% vs 28.3%; chi-squared = 79.27, p <.001), or carry diagnoses of diabetes (type 1 or 2; 9.7% vs 24.4%; chi-squared = 123.02, p <.001), or anxiety disorders (5.8% vs 9.5%; chi-squared = 16.83, p <.001). Individuals with IH were more likely to carry diagnoses of chronic fatigue syndrome (4.2% vs 1.6%; chi-squared = 45.91, p <.001), depression (31.3% vs 23.4%; chi-squared = 36.04, p <.001), and posttraumatic stress disorder (29.5% vs 26.5%; chi-squared = 5.79, p = .02).

Conclusion

Data suggest that veterans diagnosed with idiopathic hypersomnia may present with different diagnostic profiles than veterans with other hypersomnia disorders. Far more basic and clinical research is needed in IH.

805 Towards a more perfect union: interrater reliability between telemedicine and in-person evaluators in sleep disordered breathing

Introduction

Telemedicine has rapidly changed the landscape of all of clinical practice, and is now widely employed in sleep medicine. To date, the accuracy of telemedicine in identifying patients at risk for obstructive sleep apnea (OSA) is still unknown. Given differences in technique and fidelity, a perfect correlation between these two types of encounters cannot be assumed. We studied how providers using a telemedicine platform compared to providers using traditional in-person encounters in identifying risk for sleep disordered breathing.

Methods

90 participants referred to a comprehensive university sleep program were randomized to this interrater reliability study. Subjects were representative of the gender and ethnic breakdown of the outlying community. The subjects were evaluated by an in-person clinician investigator, then randomized to a second clinician investigator who performed an evaluation online using a common teleconferencing platform. Both types of evaluations included a history and physical exam. The primary outcome was pretest probability for obstructive sleep apnea. Secondary comparators included level of daytime sleepiness, snoring volume, apneas witnessed by a third party, modified Mallampati score, presence/absence of tonsils, degree of overjet bite, and severity of apnea based on home sleep testing.

Results

Interrater reliability for pretest probability of OSA was reflected in a weighted kappa value of 0.414 (SE 0.090, p=0.002). This suggests moderate agreement between the an in-person and telemedicine evaluator. Kappa values of our secondary outcomes ranged from -0.044 (degree of maxillary overjet) to 0.702 (apneas witnessed by a third party), and were generally higher for historical elements and lower for physical exam findings.

Conclusion

Evaluation for pretest probability for sleep apnea via telemedicine has a moderate interrater correlation with in-person assessment. A relatively high degree of interrater reliability for historical elements suggests that the accuracy of telemedicine for OSA is tempered by a suboptimal physical exam. Telemedicine evaluations might become more accurate through standardization. For instance, using validated scales for OSA or templated encounter scripts may help with risk-stratification, and ultimately lead to more uniform management.

1104 Increasing Accessibility of Nightmare Treatment Via Mobile Health

Introduction

Nightmares have been tied to a myriad of adverse mental health outcomes and are known to persist after treatment of other concerns such as posttraumatic stress, depression, and anxiety. When reaching clinical levels, nightmare disorder is known to effect 2-6% of the general population, Although many treatments exist for nightmare disorder and posttraumatic nightmares, Imagery Rehearsal Therapy has consistently been cited as the first line treatment. Mobile health (mHealth) technology has emerged as a viable platform from which to deliver sleep medicine interventions.

Methods

We assessed the efficacy of an Imagery Rehearsal Therapy-based mobile application (Dream EZ) developed by the National Center for Telehealth and Technology. College students (n = 99) were recruited in a two-part online study and randomized to the treatment condition or waitlist control. Repeated measures analysis of variance were used to assess the efficacy of smartphone-based mHealth application treatment (Dream EZ) in reduction of psychological symptoms (nightmare distress, PTSD symptoms, and suicide risk) as compared to waitlist control.

Results

Findings support the use of Dream EZ for nightmares distress reduction (main effect: p =.004, d = .57; interaction: p =.049, d = .41). Results regarding effectiveness of Dream EZ in relation to reduction of PTSD symptoms (main effect: p = .415, d = .17; interaction: p =.262, d = .23) showed no significant interactions between PTSD symptoms and treatment group assignment. In relation to changes in suicidality (main effect: p =.007, d = .57; interaction: p =.758, d = .07), findings were nonsignificant.

Conclusion

Use of nightmare-focused treatment through a mHealth smartphone application may be a viable avenue for promoting management of nightmare distress in college students. These findings present an opportunity to explore further options for increasing accessibility of sleep-focused treatment options in a challenging and fast-paced population.

0112 Lucid Dreaming Associated with Positive Waking Mood

Introduction

Lucid dreaming (being aware that one is dreaming) is typically a positive experience that may enhance positive mood even after waking. There is concern, however, that lucid dreaming may interfere with sleep quality. In the current experiment, participants practiced common lucid dream induction techniques over the course of a week, and kept a daily sleep and dream diary. The study objective was to assess relationships between dream lucidity and subjective sleep quality, dream emotional content, and subsequent waking mood.

Methods

There were 32 participants aged 19–33 in this open label, single arm study (mean=22.63±3.48; 6 males, 24 females). All participants completed a sleep and dream diary for 7 days that included scaled items (1–7 scale) concerning subjective sleep quality, negative and positive emotional intensity of a dream (if recalled). Participants also completed a 19-item lucidity questionnaire, and the Positive and Negative Affect Schedule. Average scores for the week were computed for all measures and Pearson’s correlations conducted between lucidity and all other measures. Participants with no dream recall (n=5) were excluded. Within-subjects analyses were undertaken by selecting each participant’s highest and lowest lucidity night (n=22; 5 participants with only minimum lucidity excluded).

Results

Positive correlations were found between lucidity and dream positive emotion (r=.490, n=27, p=.009) and positive waking mood (r=.638, n=27, p<.001); there were no other significant correlations (all p>.1). Higher lucidity was associated with more positive dream content (t(21)= -3.214, p=.004) and positive waking mood (t(25)=-4.568, p<.001); no other significant differences were observed.

Conclusion

These data indicate that lucidity is associated with positive dreams and waking mood, with no detriment to self-reported sleep quality. The findings provide preliminary support of lucid dreaming as an intervention to improve wellbeing and mood in the short term.

0159 Reduced REM Sleep Percent in Frequent Cannabis Versus Non-Cannabis Users

Introduction

THC (the main psychoactive component of cannabis) has been shown to suppress REM sleep and decrease sleep latency, although this is not consistently replicated. Increased dream vividness is reported to occur in abstinent cannabis users, although dream quality in active users is unstudied. The current study aimed to assess the effects of cannabis use compared to non-use on objective sleep measures, dream reports, and self-reported anxiety, memory, and sleep quality. To collect objective sleep data we piloted the use of a portable PSG headband that allows EEG and EOG recording at home.

Methods

12 regular cannabis users (> 3 days per week) & 9 non-users (aged 19 - 27; 43% female) participated; participants used no other drugs or alcohol on study nights. The most common form of cannabis use was smoking in joints with tobacco (range = 1 - 15 per day). Participants wore the PSG headband (the Hypnodyne ZMax) over 2 nights at home (2nd night used for analysis), and were instructed to awaken 4 times across the night to fill out brief dream reports. Objective sleep measures included TST, Sleep latency, REM latency, and REM percent. Self-report measures included the Pittsburgh Sleep Quality Index, Everyday Memory Questionnaire, and State-Trait Anxiety Index. Dream measures included recall frequency, word length, and three attributes rated on a 1–7 Likert scale - sensory vividness, emotional intensity, and bizarreness.

Results

There were no group differences on self-report measures. Cannabis users showed longer REM latency (t=2.23, p=.04) and lower REM% (U=22, p=.02); there were no other objective group differences. Cannabis users reported higher bizarreness in their dreams (t=2.07, p=.05); there were no other dream differences.

Conclusion

The study presents a novel approach to assess sleep at home and cannabis use. Significant differences emerged between users and non-users on REM latency, REM%, and dream bizarreness.

The sleep and sex survey: Relationships between sexual function and sleep

OBJECTIVE

Distress and dysfunction in sleep and sex are both very common, and have been found to be separately related to anxiety, depression, and stress. Even so, and despite evidence linking obstructive sleep apnea and erectile disfunction, the connections between sleep and sex are largely understudied.

METHOD

A large (N = 703) survey of people in the United States between 18 and 65 years old was conducted using Mechanical Turk, an on-line crowd-sourcing platform. Approximately 30% of participants were Black, Hispanic, Asian, or Native American, 8% identified as lesbian, gay or bisexual, and the sampling structure ensured an even gender distribution in each of 5 age strata. The Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), International Index of Erectile Function (IIEF), and Female Sexual Function Index (FSFI) assessed sleep and sexual dysfunction; the Perceived Stress Scale (PSS), Patient Health Questionnaire (PHQ-9), and General Anxiety Disorder scale (GAD-7) measured stress, depression, and anxiety to measure variance.

RESULTS

We found a significant connection between insomnia severity and sexual function. The relationship remained significant after accounting for the shared variability associated with depressive and anxious symptoms, and perceived stress.

CONCLUSION

Given this relationship, clinicians observing dysfunction in one area should routinely assess for dysfunction in the other. Further research will be required to determine (a) if treatment of one has an effect on the other, and (b) if this connection is related to a common psychopathological factor and/or is a conditioned association related to the commonly shared context of bed.

A Randomized Clinical Trial of Primary Care Brief Mindfulness Training for Veterans with PTSD

OBJECTIVES

Primary care (PC) patients typically do not receive adequate posttraumatic stress disorder (PTSD) treatment. This study tested if a brief mindfulness training (BMT) offered in PC can decrease PTSD severity.

METHOD

VA PC patients with PTSD (N = 62) were recruited for a randomized clinical trial comparing PCBMT with PC treatment as usual. PCBMT is a 4-session program adapted from mindfulness-based stress reduction.

RESULTS

PTSD severity decreased in both conditions, although PCBMT completers reported significantly larger decreases in PTSD and depression from pre- to posttreatment and maintained gains at the 8-week follow-up compared with the control group. Exploratory analyses revealed that the describing, nonjudging, and acting with awareness facets of mindfulness may account for decreases in PTSD.

CONCLUSION

Our data support preliminary efficacy of BMT for Veterans with PTSD. Whether PCBMT facilitates engagement into, or improves outcomes of, full-length empirically supported treatment for PTSD remains to be evaluated.

Updates on Nutraceutical Sleep Therapeutics and Investigational Research

Approximately 50% of the population will suffer from a sleep disorder over the course of their lifetime. There is increasing interest in nutraceuticals for these conditions. The quality of the evidence for the safety and effectiveness of using these supplements to treat sleep disorders varies substantially. In this review, we discuss the data about the effectiveness and safety of six commonly used plant-based sleep therapeutics: caffeine, chamomile, cherries, kava kava, L-tryptophan, marijuana, and valerian. We explore both historical uses of each substance and the current state of the literature.

Dissemination of CBTI to the non-sleep specialist: protocol development and training issues

Strong evidence supports the efficacy of cognitive behavioral therapy for insomnia (CBTI). A significant barrier to wide dissemination of CBTI is the lack of qualified practitioners. We describe challenges and decisions made when developing a CBTI dissemination program in the Veterans Health Administration (VHA). The program targets mental health clinicians from different disciplines (psychiatry, psychology, social work, and nursing) with varying familiarity and experience with general principles of cognitive behavioral therapies (CBT). We explain the scope of training (how much to teach about the science of sleep, comorbid sleep disorders, other medical and mental health comorbidities, and hypnotic-dependent insomnia), discuss adaptation of CBTI to address the unique challenges posed by comorbid insomnia, and describe decisions made about the strategy of training (principles, structure and materials developed/recommended). Among these decisions is the question of how to balance the structure and flexibility of the treatment protocol. We developed a case conceptualization-driven approach and provide a general session-by-session outline. Training licensed therapists who already have many professional obligations required that the training be completed in a relatively short time with minimal disruptions to training participants' routine work responsibilities. These "real-life" constraints shaped the development of this competency-based, yet pragmatic training program. We conclude with a description of preliminary lessons learned from the initial wave of training and propose future directions for research and dissemination.

Evaluation of the PHQ-9 Item 3 as a screen for sleep disturbance in primary care

BACKGROUND

Sleep disturbance is a significant problem for adults presenting to primary care. Though it is recommended that primary care providers screen for sleep problems, a brief, effective screening tool is not available.

OBJECTIVE

The aim of this preliminary study was to test the utility of item three of the Patient Health Questionnaire-9-item (PHQ-9) as a self-report screening test for sleep disturbance in primary care.

DESIGN

This was a cross-sectional survey of male VA primary care patients in Syracuse and Rochester, NY. Sensitivity and specificity statistics were calculated as well as positive and negative predictive value to determine both whether the PHQ-9 item-3 can be used as an effective sleep screen in primary care and at what PHQ item-3 cut score patients should be further assessed for sleep disturbance.

PARTICIPANTS

One hundred and eleven male, VA primary care patients over the age of 18 and without gross neurological impairment participated in this one-session, in-person study.

MEASURES

During the research session, patients completed several questionnaires, including a basic demographic questionnaire, the PHQ-9, and the Insomnia Severity Index (ISI).

KEY RESULTS

PHQ-9 item 3 significantly correlated with the total score on the ISI (r = 0.75, p < 0.0001). A cut score of 1 on the PHQ-9 item 3, indicating sleep disturbance at least several days in the last two weeks, showed the best balance of sensitivity (82.5%) and specificity (84.5%) as well as positive (78.4%) and negative (91%) predictive value.

CONCLUSIONS

Item 3 of the PHQ-9 shows promise as a screener for sleep problems in primary care. Using this one-item of a popular screening measure for depression in primary care allows providers to easily screen for two important issues without unnecessarily adding significant burden.
