Sleep, suicide behaviors, and the protective role of sleep medicine

Objective/BackgroundSleep disturbance is associated with suicidal thoughts and behaviors. The relationship of specific sleep disorders to suicide attempts is less well established. Whether treating sleep disorders reduces suicide attempts remains controversial. MethodsSuicide attempts, treatment utilization, and psychiatric diagnoses were extracted from electronic medical records and a suicide attempt database from the U.S. Department of Veterans Affairs. The sample (N = 60,102) consisted of patients with any record of suicide attempt in FY13-14 and a 1:1 case-control of patients with no record of attempt, who were propensity score-matched based on age, gender, and prior year mental health treatment utilization. Associations among sleep disorders and suicide attempt were examined via logistic regression. Covariates included depression, anxiety, posttraumatic stress disorder (PTSD), bipolar, schizophrenia, substance use disorder (SUD), medical comorbidity, and obesity. ResultsInsomnia (OR = 5.62; 95% CI, 5.39–5.86), nightmares (odds ratio, OR = 2.49; 95% confidence interval, CI, 2.23–2.77), and sleep-related breathing disorders (OR = 1.37; 95% CI, 1.27–1.48) were positively associated with suicide attempt after accounting for age, gender, treatment utilization, and comorbid sleep disorders. Furthermore, when controlling for depression, anxiety, PTSD, bipolar, schizophrenia, substance use disorder (SUD), medical comorbidity, and obesity, insomnia (OR = 1.51, 95% CI, 1.43–1.59) remained positively associated with suicide attempt nightmares (OR = 0.96; 95% CI, 0.85–1.09) nor sleep-related breathing disorders (OR = 0.87, 95% CI = 0.79–0.94). Additionally, sleep medicine visits 180 days prior to index date were associated with decreased likelihood of suicide attempt for individuals with sleep disorders (OR = 0.86; 95% CI, 0.79–0.94). ConclusionInsomnia is associated with suicide attempt among veterans. Sleep medicine visits were associated with a reduced risk of suicide attempt in sleep disordered patients. The assessment and treatment of sleep disorders should be considered in context of strategies to augment suicide prevention efforts.

Prescription opioid misuse, sources of opioids and reasons for opioid misuse among reproductive aged parenting women with major depressive episode

The impact of the opioid epidemic has been particularly hard on reproductive-aged parenting women. Yet, very little is known about opioid use, opioid misuse and opioid use disorder among parenting women with major depressive episode (MDE). Information on sources of opioids intended for misuse and reasons for opioid misuse among this population is also lacking. Using the 2015–2016 National Survey on Drug Use and Health, the study estimates a multinomial logistic regression model to investigate the association between MDE and opioid misuse as well as use disorder among reproductive-aged parenting women (n = 7750). Among reproductive-aged parenting women with prescription opioid use in the past 12 months, having had a MDE was associated with a higher relative risk of misusing prescription pain relievers without use disorder (RRR = 1.38, p < .001) and having a use disorder (RRR = 1.99, p < .001), relative to using prescription opioid without misuse or use disorder. However, utilization of mental health treatment mitigated the risk for opioid misuse and use disorder. A significant proportion of parenting women regardless of their MDE status identified family or friends and physicians as their main source of opioids. Relief from physical pain and help with feelings or emotions were the two primary motivations for opioid misuse among this population. These findings underscore the importance of maternal depression and mental health treatment in undertaking policy initiatives directed at the opioid crisis and highlights the role of medical providers, family and friends in targeted interventions aimed at this population.

Stigma and help-seeking: The interplay of substance use and gender and sexual minority identity

Problematic substance use is a global public health concern. However, despite high rates of substance use (SU) and related consequences, rates of treatment seeking remain low. Furthermore, individuals who identify as a gender/sexual minority (GSM) have both increased rates of problematic use and less mental health treatment utilization. Society has stigmatized both SU and GSM identity and created marginalized communities. Individuals who identify with both groups are uniquely situated in that they experience stigma related to both their SU (SU stigma) and their GSM identity (GSM stigma). The objective of this study was to examine how identifying with these stigmatized groups may influence help-seeking behavior for SU treatment. Participants were N = 171 individuals with a history of problematic SU recruited on a national scale, including N = 67 identifying as GSM. Results from multiple and logistic regression found main effects for SU stigma, such that, more anticipated SU stigma predicted more help-seeking intentions (β = 0.25, p = .04), and, controlling for SU severity, more enacted SU stigma was associated with a higher likelihood of having sought help in the past (Expβ = 4.18, p = .001). However, while we found a main effect for GSM stigma of the same direction when predicting intentions to seek help (β = 0.28, p = .02), GSM stigma was not associated with past help-seeking behavior. Lastly, the interaction between SU stigma and GSM stigma was not significant. Clinical implications are discussed, as well as future directions for subsequent research.

Barriers of mental health treatment utilization among first-year college students: First cross-national results from the WHO World Mental Health International College Student Initiative.

BackgroundAlthough mental disorders and suicidal thoughts‐behaviors (suicidal thoughts and behaviors) are common among university students, the majority of students with these problems remain untreated. It is unclear what the barriers are to these students seeking treatment.AimsThe aim of this study is to examine the barriers to future help‐seeking and the associations of clinical characteristics with these barriers in a cross‐national sample of first‐year college students.MethodAs part of the World Mental Health International College Student (WMH‐ICS) initiative, web‐based self‐report surveys were obtained from 13,984 first‐year students in eight countries across the world. Clinical characteristics examined included screens for common mental disorders and reports about suicidal thoughts and behaviors. Multivariate regression models adjusted for socio‐demographic, college‐, and treatment‐related variables were used to examine correlates of help‐seeking intention and barriers to seeking treatment.ResultsOnly 24.6% of students reported that they would definitely seek treatment if they had a future emotional problem. The most commonly reported reasons not to seek treatment among students who failed to report that they would definitely seek help were the preference to handle the problem alone (56.4%) and wanting to talk with friends or relatives instead (48.0%). Preference to handle the problem alone and feeling too embarrassed were also associated with significantly reduced odds of having at least some intention to seek help among students who failed to report that they would definitely seek help. Having 12‐month major depression, alcohol use disorder, and suicidal thoughts and behaviors were also associated with significantly reduced reported odds of the latter outcome.ConclusionsThe majority of first‐year college students in the WMH‐ICS surveys report that they would be hesitant to seek help in case of future emotional problems. Attitudinal barriers and not structural barriers were found to be the most important reported reasons for this hesitation. Experimental research is needed to determine whether intention to seek help and, more importantly, actual help‐seeking behavior could be increased with the extent to which intervention strategies need to be tailored to particular student characteristics. Given that the preference to handle problems alone and stigma and appear to be critical, there could be value in determining if internet‐based psychological treatments, which can be accessed privately and are often build as self‐help approaches, would be more acceptable than other types of treatments to student who report hesitation about seeking treatment.

Retrospective and prospective examination of outpatient mental health utilization and military career impacts.

United States (U.S.) military personnel express concerns about the potential impact of seeking mental health care on their careers. To date, there is a lack of empirical data on the association between mental health treatment utilization at a military treatment facility and career-related outcomes.

Mental Health Treatment and Unmet Mental Health Care Need Among Pregnant Women With Major Depressive Episode in the United States.

Perinatal mental health is a major public health issue in the United States. Yet, much is unknown about unmet mental health care need among pregnant women with a major depressive episode and the reasons for unmet need. Using a nationally representative data set, the study examined mental health treatment utilization, unmet mental health care need, and the reasons for unmet mental health care needs among pregnant women with a major depressive episode compared with nonpregnant women with a major depressive episode (weighted N=128,000). Of pregnant women who had experienced a major depressive episode, 49% reported receiving any mental health treatment, compared with 57% of nonpregnant women with a major depressive episode. The study also found financial barriers to be the primary reason for unmet mental health care need. Despite current treatment guidelines and policy initiatives, most women with major depressive episodes go without any treatment utilization and perceive an unmet need for their mental health care.

Mental health symptoms and treatment utilization among trauma-exposed college students.

Universities have demonstrated growing awareness of students impacted by interpersonal violence (e.g., sexual and physical assault) and veterans/service-members with combat-related trauma because of their sizable presence on campuses and unique vulnerabilities. This study sought to describe impacts of these two forms of trauma exposure on students' mental health and academic functioning and to compare mental health service utilization among students based on their experiences of trauma exposure. To acquire a large, national sample of college students, we examined archival data from the Fall 2015 American College Health Association National College Health Assessment, a yearly, web-based survey which represented a sample of 19,861 students from 40 institutions. Twenty percent of the students had experienced interpersonal victimization in the last 12 months, combat exposure, or both. Compared with other groups, interpersonal violence survivors reported the most negative impacts on mental health and interference with academic performance. Service utilization rates among trauma-exposed students ranged from 52% to 84%, and students who had experienced recent interpersonal violence were the most likely to have received services. With a national sample, this study confirms that trauma-exposed students report poor mental health. Service utilization is high among this population, but campus-based mental health services appear to remain underutilized. Outreach efforts by student life professionals and campus clinicians targeting demographic subgroups could enhance utilization and accessibility of campus resources.

Characterizing Mental Health Treatment Utilization among Individuals Exposed to the 2001 World Trade Center Terrorist Attacks 14⁻15 Years Post-Disaster.

Following the World Trade Center (WTC) attacks in New York City (NYC) on 11 September 2001 (9/11), thousands in NYC experienced significant stress reactions and disorders, presenting an immediate need for counseling and treatment. While other studies documented post-9/11 mental health treatment utilization, none have data more than two years post-disaster. We used data from 35,629 enrollees of the WTC Health Registry, a longitudinal cohort study of those exposed to the WTC attacks, to examine predictors of counseling after 9/11, the types of practitioners seen, and the perceived helpfulness of therapy up to 15 years post-disaster. Among enrollees, 37.7% reported receiving counseling at some time after 9/11. Predictors of seeking counseling included race/ethnicity, age at 9/11, education level, exposure to the WTC attacks, other traumatic experiences, mental health symptomology, and pre-9/11 counseling. Whites and Hispanics, those who were children on 9/11, and those with high levels of exposure to the WTC attacks sought counseling soonest after 9/11. Among those who sought counseling, Blacks, Asians, and those with lower education and income were less likely to see mental health specialists and more likely to see general practitioners or religious advisors. Finally, among those who sought recent counseling, women, Blacks, those aged ≥65 years, and those with very high WTC exposures were more likely to rate their recent counseling as very helpful. This study used data up to 15 years post-disaster to document mental health treatment utilization patterns, trends, and disparities that have implications for future preparedness plans and needs assessments.

Differences in Utilization of Mental Health Treatment Among Children and Adolescents With Medicaid or Private Insurance.

Children and adolescents with diagnosed mental disorders may require developmentally tailored interventions. However, little is known about the difference in mental health treatment utilization among children by age group and health insurance coverage. Using the 2016 MarketScan database, the study examined treatment utilization patterns by health insurance coverage (private and Medicaid) and developmental age group (preschool-age children, ages 3-5; young children, ages 6-11; and adolescents, ages 12-17). Psychiatric medication only was the most common form of treatment utilization among all children, regardless of developmental age group or insurance coverage. Specifically, psychiatric medication only was received by 38% of preschool-aged children with Medicaid and 42% of those with private insurance, 43% of young children with Medicaid and 39% of those with private insurance, and 55% of adolescents with Medicaid and 49% of those with private insurance. Given that evidence-based practices suggest that combined treatment with psychiatric medications and psychotherapy may be the recommended treatment, the study's findings raise potential concerns about the high use of medication-only treatment.

Behavioral health treatment utilization among individuals with co-occurring opioid use disorder and mental illness: Evidence from a national survey

BackgroundPast research shows that among individuals with substance use disorders, the presence of a co-occurring mental illness can influence the initiation, course, and success of behavioral health treatment, but little research has examined people with opioid use disorder (OUD) specifically. MethodsUsing the 2008–2014 National Survey on Drug Use and Health, this study examines the utilization of substance use disorder and mental health treatment among individuals with OUD and different degrees of mental illness severity. The study also examined types of treatment, perceived unmet need for treatment, and barriers to care. Results47% of individuals with OUD and co-occurring mild/moderate mental illness did not receive any behavioral health treatment, and 21% of those with co-occurring serious mental illnesses did not receive any behavioral health treatment. Among those with OUD and co-occurring mild/moderate mental illness, 16% reported receiving both substance use disorder and mental health treatment; among those with co-occurring serious mental illness the rate was 32%. The most common form of treatment was prescription medication for mental health, and this was true regardless of whether or not the individual had any mental illness. More than 50% of the study population reported financial difficulties as a barrier to treatment. ConclusionA high proportion of individuals with OUD and co-occurring mental illness are not receiving needed care. However, nearly one in five of those with OUD but no diagnosed mental illness is receiving prescription medication for mental illness. These findings suggest that there is a need to better facilitate access to and coordinate behavioral health care across settings for individuals with OUD.

The Impact of Psychiatric Symptoms on Tuberous Sclerosis Complex and Utilization of Mental Health Treatment

BackgroundTuberous sclerosis complex (TSC) is a multisystem, neurocutaneous disorder with a spectrum of TSC-associated neuropsychiatric disorders. The most common neuropsychiatric manifestations in the pediatric and adult populations are cognitive concerns, depression, and anxiety. Previous research suggests that while 90% of individuals with TSC have some TSC-associated neuropsychiatric disorders features, only 20% receive treatment, leading to a 70% treatment gap. MethodsThis web-based study used validated measures in conjunction with researcher-designed questions to evaluate perception of disease severity, presence of anxiety and depression, and the utilization and barriers toward mental health services among adults with TSC. ResultsThe Beck Anxiety Inventory, Beck Depression Inventory-II, and Brief Illness Perception Questionnaire indicated that our overall study population had mild symptoms of anxiety, minimal depression, and a moderate perception of disease severity. Notably, the difference between the median depression score for men and women was statistically significant with men scoring higher than women (P = 0.02). Of 69 respondents, 57% (n = 39) reported receiving mental health treatment at some point over their lifetime. In both the mental health treatment group and the nonmental health treatment group, cost was more often indicated as a barrier to accessing mental health resources (treatment group: cost = 51% and stigma = 21%; nontreatment group: cost = 27% and stigma = 20%). ConclusionsTSC disease severity had a moderate and low-moderate association with anxiety and depression, respectively. Regardless of past utilization, respondents had a positive outlook towards the use of mental health services with the major barrier being cost.

Substance Use Disorders Among Veterans in a Nationally Representative Sample: Prevalence and Associated Functioning and Treatment Utilization

Several epidemiological studies have reported that veterans and nonveterans have comparable substance use disorder (SUD) prevalence and SUD treatment rates for SUD and treatments of several types. No studies have compared functioning among veterans with SUD to veterans without SUD or to nonveterans. We investigated the prevalence of past-year and lifetime SUD (based on criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), overall and by substance, and estimated the association with physical and mental health functioning and treatment utilization and need among veterans and nonveterans in a nationally representative sample. Predicted prevalence of any past-year SUD, with and without tobacco use disorder (TUD), among veterans was 32.9% and 17.1%, and prevalence of any lifetime SUD, with and without TUD, was 52.5 and 38.7%, respectively. Veterans had higher prevalence of past-year and lifetime SUD for some substances (e.g., tobacco, alcohol) but not others (e.g., cannabis, opioid). Lower physical and mental health functioning was found among veterans, relative to nonveterans, and participants with SUD, relative to those without SUD, and veterans with SUD reported the lowest functioning across all domains. More veterans than nonveterans received any SUD treatment and SUD treatment in specific domains (e.g., self-help). About 70% of veterans with past-year SUD did not receive treatment, but only 5.4% reported needing and not receiving treatment. Relative to nonveterans, veterans have higher prevalence of past-year TUD and lifetime alcohol use disorder or TUD and lower physical or mental health functioning. A minority of veterans receive SUD treatment, and few report unmet need for treatment.

Racial and ethnic differences in mental health service utilization in suicidal adults: A nationally representative study

The current study examined racial/ethnic differences in utilization of mental health services in a nationally representative sample of suicidal adults. Data were extracted from the National Survey on Drug Use and Health (NSDUH) from 2009 to 2016. Participants consisted of adults with severe suicidal ideation and/or behavior in the past 12 months (unweighted n = 17,338). Multivariate logistic regression analyses were conducted to assess racial/ethnic differences in mental health treatment utilization after adjusting for health insurance status, family income, age, sex, and major depression. Analyses were conducted separately for suicidal ideators with no attempts (i. e., “pure” ideators; unweighted n = 14,578) and for suicide attempters (unweighted n = 2760) for psychiatric inpatient and outpatient care, respectively. Racial/ethnic disparities in mental health treatment utilization were less apparent for inpatient care and most evident for outpatient care. For inpatient care, no racial/ethnic differences were observed among suicidal ideators with no attempts. Among suicide attempters, only Hispanics were less likely than non-Hispanic whites to receive inpatient care. In contrast, for outpatient care, treatment use was lower for all racial ethnic minorities, except Native American and multiracial individuals, relative to non-Hispanic whites among suicidal ideators with no attempts. Outpatient service use was also lower for non-Hispanic blacks, Hispanics, and multiracial individuals relative to non-Hispanic whites among suicide attempters. This pattern of findings is consistent with the possibility that suicidal racial/ethnic minorities may delay use of mental health services until clinical severity becomes such that elevated clinical care (i.e., inpatient treatment) is required. Future research accounting for these disparities is warranted.

Assessing the relationship between fear of cancer recurrence and health care utilization in early-stage breast cancer survivors.

The purpose of this study was to determine whether fear of cancer recurrence (FCR) is associated with greater health care utilization (HCU) in early-stage breast cancer survivors. Three hundred early-stage breast cancer survivors diagnosed within the past 7years reported on FCR as well as calls and visits to oncology providers and primary care providers during the preceding 3months. Participants also reported on use of mental health services and psychotropic medications since diagnosis. Structural equation modeling was used to create a latent FCR factor and evaluate this factor as a predictor of various HCU outcomes controlling for age at diagnosis, years since diagnosis, generalized anxiety, objective risk of recurrence, and number of comorbidities. FCR predicted more visits to both oncology providers (RR = 1.53, p = .002) and primary care providers (RR = 1.31, p = .013), as well as more phone calls to oncology providers (RR = 2.08, p = .007). FCR was not a significant predictor of phone calls to primary care providers (RR = 1.39, p = .054), utilization of mental health treatment (OR = 1.27, p = .362), or use of psychotropic medications (OR = 1.37, p = .178). FCR was associated with increases in some types of HCU, which may reflect excessive medical reassurance-seeking and lead to unnecessary medical costs. FCR is a serious concern that warrants greater attention to reduce distress-related health care utilization. Utilization of mental health services to address FCR may represent higher-value health care.

Sex Differences in Correlates of Risk and Resilience Associated with Military Sexual Trauma

ABSTRACTMilitary sexual trauma (MST) is associated with a range of negative mental and physical health outcomes. Investigations of potential sex-based differences in outcomes in MST survivors have been inconsistent with little work evaluating psychosocial correlates of resilience (e.g., social support, humor, capacity to adapt to change). Data were analyzed from 115 U.S. Veterans reporting a history of MST who participated in the nationally representative National Health and Resilience Veterans Study (NHRVS) to examine sex-based correlates of risk and resilience. Compared with female MST survivors (n = 56; 42.9%), male MST survivors (n = 59; 57.1%) reported increased lifetime traumatic events, hostility, and history of drug use disorder, whereas female veterans reported increased lifetime PTSD symptoms. There were no differences in past-month PTSD symptom severity, physical health, suicidal ideation/attempts, resilience factors, or rates of mental health treatment utilization. Results suggest male and female MST survivors may have differential risk for drug use disorder, hostility, and PTSD symptoms. Results further underscore the importance of considering sex differences in the assessment and treatment of MST survivors. Improved understanding of outcomes and factors of risk and resilience in MST survivors may facilitate tailored intervention, treatment, outreach, and possibly prevention.

Mental Health Disparities Among College Students of Color

PurposeUnderstanding the mental health needs of students of color is a growing priority on college and university campuses nationwide. This study aims to capture the state of mental health among students of color, including the prevalence of mental health problems and treatment utilization. MethodsThe sample is comprised of 43,375 undergraduate and graduate students at 60 institutions that participated in the survey-based Healthy Minds Study from 2012 to 2015. These data include over 13,000 students of color; we look separately at African-American, Latinx, Asian/Asian American, and Arab/Arab American students. Data are analyzed at the individual level using bivariate and multivariate modeling to elucidate variations across race/ethnicity. We examine symptom prevalence (measured by validated screens such as the Patient Health Questionnaire-9 for depression), help-seeking behaviors, and related factors (including knowledge and stigma). ResultsAcross race/ethnicity, we find modest variation in symptom prevalence and larger variation in service utilization. Overall, treatment use is lower among students of color relative to white students, even when controlling for other variables in regression models. Asian/Asian American students have the lowest prevalence of treatment, at only 20% among those with apparent mental health conditions. Attitudes related to mental health treatment also vary significantly and help to explain the primary findings. ConclusionsCollege students of color represent a disparities population based on greater levels of unmet mental health needs relative to white students. This paper takes an important step toward understanding these needs and points to implications for future research and practice.

The associations between suicidality and mental health factors and pain interference in veterans being referred to primary care mental health integration

In veterans being referred to a primary care-mental health integration (PCMHI) program, the Behavioral Health Laboratory, we sought to identify correlates of suicidal ideation severity and suicide attempts using the ideation-to-action framework among pain interference, psychiatric disorders, and treatment factors. Veterans (n = 17,176) referred to the Behavioral Health Laboratory received a structured assessment that included past-year suicidal thoughts and behaviors, psychiatric symptoms, substance use, psychotropic medication use, and mental health treatment utilization. Nearly 50% of participants reported at least passive suicidal ideation. While psychiatric symptoms differentiated passive ideators, active ideators, and suicide attempters from non-suicide ideators, there were no significant differences among active ideators and attempters. Additionally, attempters differed from passive ideators in terms of drug use, mental health treatment, psychotropic medication use, mania, and psychosis. Pain interference was significantly associated with suicidal ideation severity in bivariate analyses, but not for the adjusted analyses. PCMHI is a setting seeing a high rate of suicidal ideation and may serve as a critical setting to implement suicide prevention efforts.

Barriers to Mental Health Treatment Utilization in Wards 7 and 8 in Washington, DC: A Qualitative Pilot Study.

Purpose: There is a paucity of data on barriers to mental health treatment utilization among residents of Wards 7 and 8 in Washington, DC, despite exposure to many environmental factors that are associated with poor mental health outcomes and the high prevalence of mental health problems among residents. The objective of this study was to examine barriers to mental healthcare utilization among residents of Wards 7 and 8.Methods: This study included semi-structured, in-depth interviews with five key informants who lived or spent significant time in Wards 7 or 8 in Washington, DC, which are the wards served by Paving the Way MSI, a behavioral health clinic that served as a partner organization in the study.Results: Barriers to mental health treatment utilization existed at a variety of social-ecological levels, including the individual/interpersonal level, the provider/mental health system level, the community level, and the societal level. Major barriers included fear and trust/distrust in the medical system, lack of social support, the model of mental healthcare, lack of patient-centered care, limited access to mental health services, stigma of mental illness and mental health treatment, and poverty.Conclusion: This study highlights the need to address barriers to mental health treatment utilization at multiple social-ecological levels. Future studies should examine perspectives from residents with mental health problems in these wards to gain a more thorough understanding of the barriers to treatment. Funding is needed to support efforts to increase mental health treatment utilization among residents of Wards 7 and 8.

Postrehabilitation Mental Health Treatment Utilization in Veterans With Traumatic Brain Injury: A VA TBI Model Systems Study.

To identify preinjury variables related to mental health treatment utilization at 2 years post-traumatic brain injury (TBI). Veterans Affairs (VA) TBI Model Systems includes 5 VA Polytrauma Rehabilitation Centers. Veterans and service members enrolled in TBI Model Systems who completed the year 2 follow-up assessment and provided mental health information. Sample was largely male (97%) and White (72%), with median age of 30 years. Participants with elevated mental health symptoms were identified by measures of depression, anxiety, and posttraumatic distress; suicide attempt in the past year; or problematic substance use in the past year. Forty-seven percent of participants had elevated mental health symptoms at 2 years postinjury. Among those with elevated symptoms, comparisons were made between those who sought mental health treatment in past year and those who did not. Demographic, historic, environmental, psychological/mental health, and injury/rehabilitation variables. Within the sample, 23% denied utilizing mental health services. Nonutilizers were more likely to deny a preinjury mental health treatment history, to report problematic substance use at year 2, and to report lower levels of internalizing symptoms than the treatment utilizers. Veterans and service members with elevated mental health symptoms may require tailored tactics to promote treatment utilization post-TBI.
