Psychological and Behavioral Interventions for Managing Insomnia Disorder: An Evidence Report for a Clinical Practice Guideline by the American College of Physicians

Sleep difficulties, including the inability to initiate or maintain sleep, are common in adults. Sleep difficulties are typically transient; however, when they become chronic and cause distress or daytime dysfunction, insomnia disorder may be present. The American Psychiatric Associations Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, defines insomnia disorder as a predominant symptom of difficulty with sleep initiation, difficulty maintaining sleep, or early-morning waking with inability to return to sleep causing clinically significant distress or impairment in activities, occurring at least 3 nights per week for 3 months or more (1). Furthermore, individuals must have adequate opportunity for sleep and the symptoms cannot be better explained by medical or mental conditions, including another sleep disorder (such as breathing-related sleep disorder), or medication or substance use. The term previously used for insomnia disorder is chronic insomnia (14), for which diagnostic criteria required sleep problems lasting from weeks to months. These criteria are empirically similar to current criteria for insomnia disorder. We use the term insomnia disorder even though much of the primary research has used other terminology (such as chronic insomnia and persistent insomnia). Between 6% and 10% of adults meet the diagnostic criteria for insomnia disorder (4). Duration ranges from 1 to 20 years across longitudinal studies (5). Insomnia disorder is more common in female patients and older adults (6, 7). Older adults typically report difficulty maintaining sleep as opposed to initiating sleep, which is common in younger adults (8). Many treatment types are available once insomnia disorder is accurately diagnosed by using established diagnostic criteria (4, 9). These include psychological and behavioral treatments, pharmacologic therapies, and complementary and alternative medicine. The American Academy of Sleep Medicine recommends psychological and behavioral interventions and supports short-term supplementary medication (9, 10). Psychological and behavioral interventions include cognitive behavioral therapy for insomnia (CBT-I), multicomponent behavioral therapy (brief behavioral therapy for insomnia), and single-component interventions (such as sleep hygiene and education, stimulus control, sleep restriction, and relaxation) (Table). Cognitive behavioral therapy for insomnia most commonly includes behavioral therapies (sleep restriction, stimulus control, relaxation training), cognitive therapy (cognitive restructuring) to change dysfunctional beliefs about sleep, as well as sleep hygiene education (3). Multicomponent behavioral therapies combine several behavioral therapies and do not include a cognitive component. Table. Psychological and Behavioral Interventions for Insomnia Disorder* Treatment goals include improving quality and quantity of sleep and associated impairments (10). Ideally, meaningful improvements in global outcomes measuring sleep and associated distress and dysfunction are realized. The Insomnia Severity Index (ISI) and the Pittsburgh Sleep Quality Index (PSQI) are commonly used for measuring global outcomes. Sleep outcomes include specific sleep variables (sleep-onset latency [SOL], wake time after sleep onset [WASO], total sleep time [TST], sleep efficiency (sleep time/time in bed), and sleep quality. Sleep variables can be measured objectively (with polysomnography or actigraphy) or subjectively (sleep diaries). Guidelines suggest monitoring symptoms with sleep diaries and polysomography is not indicated (10). We conducted a systematic review on the management of insomnia disorder for the Agency for Healthcare Research and Quality (11). This article reports evidence on psychological and behavioral interventions. Another article reports on the evidence on pharmacologic interventions and the comparison of pharmacologic interventions with psychological and behavioral interventions (12), and the full report provides evidence on complementary and alternative interventions. This evidence was used by the American College of Physicians to develop the guideline on the treatment of insomnia disorder in primary care. Evidence summarized here enhances previous reports (1315) by providing a comprehensive evaluation of psychological and behavioral interventions across all delivery modes with a primary emphasis on global outcomes. Methods Data Sources and Searches We searched bibliographic databases, including MEDLINE, Embase, and PsycINFO via Ovid, as well as the Cochrane Library, to identify randomized, controlled trials published from 2004 through September 2015 (Supplement). We identified studies published before 2004 by searching the citations in relevant systematic reviews. Supplement. Supplementary Material Study Selection Two investigators independently reviewed titles and abstracts of search results to identify potentially eligible references. Two investigators independently screened full texts of those references to determine whether inclusion criteria were met. We included randomized, controlled trials of psychological and behavioral interventions if they enrolled adults, provided at least 4 weeks of treatment, reported global or sleep outcomes, and were published in English. We excluded trials enrolling pure subgroups of patients with major medical conditions or conditions that may explain the sleep problems (such as menopause, pregnancy, and neurologic conditions). Data Extraction and Quality Assessment Risk of bias was independently assessed by two investigators using an instrument developed using Agency for Healthcare Research and Quality guidance (16) and was summarized as low, medium, or high on the basis of summary risk of bias and confidence that results were believable given limitations. Study, participant, and treatment characteristics; outcomes; and adverse events were extracted from eligible trials with low or moderate risk of bias. Data Synthesis and Analysis We used RevMan 5.2 (Nordic Cochrane Center) for pooling when adequate data were provided and populations, interventions, and outcomes were similar (17). DerSimonian and Laird random-effects estimates of risk ratios and absolute risk differences with 95% CIs were calculated for categorical outcomes, and weighted mean differences (WMDs) and/or standardized mean differences with 95% CIs were calculated for continuous outcomes. We assessed heterogeneity with the Cochran Q test and I 2 statistic (75% indicates substantial heterogeneity) (18). We analyzed the general adult population and older adults separately because sleep measures vary. We used established minimum important differences (MIDs) to capture clinical significance in global outcomes. The MID for the ISI is a 6-point change from baseline (19). Trials that conducted remitter or responder analysis on the basis of established MID offer simplistic interpretation. When trials provided mean scores, we interpreted WMDs in relation to MID by using the method of Johnson and colleagues (20). Weighted mean differences equal to or greater than the MID suggest that many patients gain important benefits, WMDs greater than half the MID but less than the MID suggest that an appreciable number of patients benefit, and WMDs less than half of the MID suggest that patients do not achieve important benefits (20). One investigator assessed strength of evidence for unique comparisons as high, moderate, low, or insufficient (21); assessments were confirmed through consensus. Role of Funding Source This topic was nominated to and funded by the Agency for Healthcare Research and Quality Effective Health Care Program. Key informants representing various perspectives offered suggestions as refined the review scope. Our draft protocol was shared with a technical expert panel that had the opportunity to review the draft report. The American College of Physicians provided support for this manuscript preparation. The authors are solely responsible for its contents. Results We identified 3572 citations; 559 required full-text review after title and abstract screening (Appendix Figure 1). Seventy-six articles (2297) reporting on 70 trials that compared psychological and behavioral interventions with inactive controls or other psychological and behavioral interventions were eligible. We extracted data and analyzed results for 60 trials with low to moderate risk of bias. We grouped trials by intervention type and comparison. Interventions for CBT-I had cognitive and behavioral components; multicomponent behavioral therapy interventions had several behavioral components and no cognitive component; and single-component interventions included sleep restriction, stimulus control, and relaxation. Appendix Figure 1. Summary of evidence search and selection. Intervention type totals do not equal total references because several trials were used in the analysis for 2 different types of interventions. RCT = randomized, controlled trial. Eligible trials (Tables 1 and 2 of the Supplement) enrolled individuals most commonly diagnosed with chronic insomnia according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, with mean durations of several years. Participants were predominantly female and white. Trials were conducted in the United States, Canada, the United Kingdom, Sweden, Australia, Norway, Scotland, the Netherlands, and China. Mean age was mid-40s in general adult populations and lower 70s in older adults. Baseline ISI scores were approximately 17, indicating moderate severity, and baseline SOL was more than 45 minutes. Comparisons varied across trials. Inactive controls included information (such as sleep hygiene education) or waitlist; trials infrequently used sham treatments. Adverse effects were rarely reported. Withdrawals were not always reported by group. Evidence on adverse effects and withdrawals was insufficient for all comparisons. We assessed strength of

Care-Delivery Interventions to Manage Agitation and Aggression in Dementia Nursing Home and Assisted Living Residents: A Systematic Review and Meta-analysis

Correlates of Human Immunodeficiency Virus/Sexually Transmitted Infection (HIV/STI) Testing and Disclosure among HIV-Negative Collegiate Men Who Have Sex with Men.

Abstract Objective: To determine the extent to which personal, behavioral, and environmental factors are associated with human immunodeficiency virus/sexually transmitted infection (HIV/STI) testing and disclosure. Participants: Nine hundred thirty HIV-negative collegiate men who have sex with men (MSM) who completed an online survey about alcohol use and sexual behavior. Methods: Correlates of testing and disclosure significant in bivariate analyses (p < .05) were grouped into personal, behavioral, or environmental factors and entered into multivariable logistic regression models. Results: About half of participants tested for HIV (51.9%) and for STIs (45.8%) at least annually. Over half (57.8%) of participants always/almost always discussed HIV status with new sex partners; 61.1% with new unprotected sex partners. Personal and behavioral factors (age and outness) explained differences in testing, and the behavioral factor (routine testing) explained differences in disclosure. Conclusions: Collegiate MSM should be supported in coming out, encouraged to engage in routine testing, and counseled on discussing HIV/STI status with potential sex partners.

Knowledge and prevention practices among U.S. Pregnant immigrants from Zika Virus outbreak areas

We administered an anonymous survey to assess knowledge, attitudes, and prevention practices related to the Zika virus among pregnant women residing in Texas. Multivariate logistic regression models controlling for age, race/ethnicity, education, and number of years in the United States assessed differences between women born in outbreak areas (N = 390) versus those born in the United States (N = 249). Results demonstrated that most women wanted more information on the Zika virus and desired to obtain it from their physician. The majority did not know that the Zika virus could be spread through sex with an asymptomatic partner or how often those infected were symptomatic. Few women took precautions to avoid mosquito bites. Only 40% reported frequently using repellent; 21% stated that cost was problematic and almost half were concerned about use during pregnancy. Three-fourths stated they would agree to vaccination, if available. Compared with U.S.-born women, those born in outbreak areas were more likely to have already discussed the Zika virus with their doctor (adjusted odds ratio [aOR] = 1.86, 95% confidence interval [CI] = 1.27, 2.71) and identify microcephaly as the most common birth defect (aOR = 2.59, 95% CI = 1.78, 3.76). Moreover, women born in outbreak areas were less likely to desire to keep it a secret if they became infected (aOR = 0.47, 95% CI = 0.31, 0.71). This study found that, regardless of birthplace, pregnant women need more education on the Zika virus disease and assurance regarding the safety of using repellent during pregnancy. They also need financial assistance for repellent, especially if living in states where transmission by mosquitos has been reported.

Self-reported prenatal influenza vaccination and early childhood vaccine series completion.

BACKGROUND No studies have examined associations between prenatal vaccination and childhood vaccination. Mothers who refuse influenza vaccinations during pregnancy report similar attitudes and beliefs to those who refuse vaccinations for their children. The objective of this study was to examine the association between self-reported prenatal influenza vaccination and early childhood vaccination. METHODS A retrospective cohort study was conducted with existing surveillance data from 4022 mothers who responded to the 2009-2011 Minnesota Pregnancy Risk Assessment Monitoring System survey and child vaccination records from the Minnesota Immunization Information Connection database. The childhood vaccine series outcome included the following vaccines: diphtheria, tetanus, and pertussis; poliovirus; measles, mumps, and rubella; Haemophilus influenzae type b (Hib); hepatitis B; varicella; and pneumococcal conjugate. To evaluate the association between self-reported prenatal influenza vaccination and early childhood vaccination, unadjusted and adjusted logistic regression was used to estimate log odds for childhood vaccination status, while margins post-estimation commands were used to obtain predicted probabilities and risk differences. RESULTS Vaccine series completion was 10.86% higher (95% confidence interval (CI) 7.33%-14.40%, adjusted and weighted model) in children of mothers who had a prenatal influenza vaccine compared to those who did not. For individual vaccines in the recommended series, risk differences ranged from 7.83% (95% CI 5.37%, 10.30%) for the Hib vaccine to 10.06% (95% CI 7.29%, 12.83%) for the hepatitis B vaccine. CONCLUSION Self-reported prenatal influenza vaccination was associated with increased early childhood vaccination. More research is needed to confirm these results and identify potential intervention strategies.

Screening of gestational carriers in the United States

OBJECTIVE To assess medical and psychosocial screening and evaluation received by gestational carriers and compare those using agencies to those not using agencies. DESIGN Cross-sectional questionnaire. SETTING Not applicable. PATIENT(S) A total of 204 women who completed a survey on their experiences as gestational carriers in the United States. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Self-reported screening received before gestational carrier pregnancies. RESULT(S) Overall, 97.1% of gestational carriers had a complete medical evaluation and 94.6% had an evaluation or counseling by a mental health professional. Most participants indicated that they had been informed of at least some medical risks (92.6%) and psychological considerations (89.7%). Participants most often recalled being informed of the risks of multiple pregnancy (89.2%) and medical procedures and medications (87.2%), but least often recalled being informed about the risks of impact on their own employment (46.6%) and to their own children (61.3%). There were no differences in outcome measures between those using an agency and those who did not. CONCLUSION(S) Self-reported screening and evaluation was high, but still not 100% on all measures. Further education of providers regarding guidelines for the screening and evaluation of gestational carriers may be needed.

Relationship between maternal experiences and adolescent HPV vaccination

ABSTRACT The human papillomavirus (HPV) vaccine has been available for over a decade but its uptake rate is still low. To explore the relationship between the HPV vaccination status of a child and their mothers beliefs, behaviors and knowledge, we surveyed 1497 women with at least one child aged 9–17 y between September 2011 and November 2015. Physician recommendation was the most important factor associated with reported child vaccination status. Mothers who reported receiving a provider recommendation for the HPV vaccine were 32 times more likely to have a child who had been vaccinated compared with mothers who did not report provider recommendation (aOR) = 32.17; 95% CI: 21.77, 47.54). Knowing someone who had received the vaccine was also strongly associated with vaccination uptake (59% vs 12%, p < .001). Additionally, prior HPV diagnosis (aOR = 1.91; 95% CI: 1.18, 3.10) and knowing someone with cervical cancer (aOR = 1.38; 95% CI: 1.01, 1.89) were associated with child vaccination status. Mothers who perceived moderate to high risk for their child contracting HPV or developing genital warts or cervical cancer were more likely to report that their daughters (but not their sons) had been vaccinated.

Examining maternal beliefs and human papillomavirus vaccine uptake among male and female children in low-income families

PURPOSE This study examines within-family differences in the uptake of the HPV vaccine and HPV-related beliefs by children׳s sex. METHODS From a 2011-2013 survey of mothers of children aged 9-17 years in Texas, mothers with both male and female children (n=350) were selected. RESULTS Mothers were more likely to report having initiated and completed HPV vaccination for their daughters than sons. Mothers did not express differences by children׳s sex in HPV-related beliefs. Among those who had not completely vaccinated either child, mothers were more likely to report they wanted their daughters compared to sons vaccinated and were more likely to report feeling confident they could get their daughters vaccinated than their sons. CONCLUSION In this population, mothers were more likely to report HPV vaccination of and motivation to vaccinate daughters compared to sons, although maternal beliefs about HPV did not differ by children׳s sex.

US medical students’ willingness to offer the HPV vaccine by vaccination status

We surveyed third-year medical students to assess whether personal vaccination status was associated with willingness to recommend the human papillomavirus vaccine to patients. A total of 231 students completed an anonymous survey evaluating their knowledge, attitudes, and personal vaccine history. Of 122 female students, 81 (66.4%) reported initiating the vaccine, as did 16 of 109 males (14.7%). Females and students ⩽25years old were more likely to be vaccinated. Knowledge did not vary by vaccination status, but anticipated behaviors did. Vaccinated students reported greater willingness to vaccinate adolescents before 15-16years of age (92.1% vs. 78.6%, p=0.008) and discuss vaccination at any type of medical visit (100% vs. 89.7%, p<0.001). Our findings suggest that prior experiences with the HPV vaccine may influence a providers future actions. Thus, interventions that increase awareness of this relationship as well as vaccination rates among health care students may be beneficial.

Prevention practices among United States pregnant women who travel to Zika Outbreak Areas

We surveyed pregnant women from the United States to assess the prevention practices they used when traveling to countries with ongoing Zika virus (ZIKV) outbreaks. Of the 749 who agreed to participate, 710 completed the surveys travel questions and 59 of those had traveled to a ZIKV outbreak area in the past 12 months. Only 43% of the women who had traveled to ZIKV outbreak areas reported frequently using mosquito repellant with 32% stating they did not use it at all. They also did not frequently use other recommended methods to prevent mosquito bites. With the established risks to babies born to women who contract the ZIKV during pregnancy, it is a great concern that a large number of women who travel to outbreak areas during pregnancy are not protecting themselves against mosquito bites. Pregnant women need to be educated on the importance of taking precautions.
