Identifying factors impacting missingness within smartphone-based research: Implications for intensive longitudinal studies of adolescent suicidal thoughts and behaviors.

Intensive longitudinal research-including experience sampling and smartphone sensor monitoring-has potential for identifying proximal risk factors for psychopathology, including suicidal thoughts and behaviors (STB). Yet, missing data can complicate analysis and interpretation. This study aimed to address whether clinical and study design factors are associated with missing data and whether missingness predicts changes in symptom severity or STB. Adolescents ages 13- to 18 years old (N = 179) reporting depressive, anxiety, and/or substance use disorders were enrolled; 65% reported current suicidal ideation and 29% indicated a past-year attempt. Passively acquired smartphone sensor data (e.g., global positioning system, accelerometer, and keyboard inputs), daily mood surveys, and weekly suicidal ideation surveys were collected during the 6-month study period using the effortless assessment research system smartphone app. First, acquisition of passive smartphone sensor data (with data on ∼80% of days across the whole sample) was strongly associated with survey data acquisition on the same day (∼44% of days). Second, STB and psychiatric symptoms were largely not associated with missing data. Rather, temporal features (e.g., length of time in study, weekends, and summer) explained more missingness of survey and passive smartphone sensor data. Last, within-participant changes in missing data over time neither followed nor predicted subsequent change in suicidal ideation and psychiatric symptoms. Findings indicate that considering technical and study design factors impacting missingness is critical and highlight several factors that should be addressed to maximize the validity of clinical interpretations in intensive longitudinal research.

Intensive Longitudinal Assessment of Adolescents to Predict Suicidal Thoughts and Behaviors

Suicide is a leading cause of death among adolescents. However, there are no clinical tools to detect proximal risk for suicide. Participants included 13- to 18-year-old adolescents (N= 103) reporting a current depressive, anxiety, and/or substance use disorder who owned a smartphone; 62% reported current suicidal ideation, with 25% indicating a past-year attempt. At baseline, participants were administered clinical interviews to assess lifetime disorders and suicidal thoughts and behaviors (STBs). Self-reports assessing symptoms and suicide risk factors also were obtained. In addition, the Effortless Assessment of Risk States (EARS) app was installed on adolescent smartphones to acquire daily mood and weekly suicidal ideation severity during the 6-month follow-up period. Adolescents completed STB and psychiatric service use interviews at the 1-, 3-, and 6-month follow-up assessments. K-means clustering based on aggregates of weekly suicidal ideation scores resulted in a 3-group solution reflecting high-risk (n= 26), medium-risk (n= 47), and low-risk (n= 30) groups. Of the high-risk group, 58% reported suicidal events (ie, suicide attempts, psychiatric hospitalizations, emergency department visits, ideation severity requiring an intervention) during the 6-month follow-up period. For participants in the high-risk and medium-risk groups (n = 73), mood disturbances in the preceding 7 days predicted clinically significant ideation, with a 1-SD decrease in mood doubling participants' likelihood of reporting clinically significant ideation on a given week. Intensive longitudinal assessment through use of personal smartphones offers a feasible method to assess variability in adolescents' emotional experiences and suicide risk. Translating these tools into clinical practice may help to reduce the needless loss of life among adolescents.

The relevance of the interpersonal theory of suicide for predicting past-year and lifetime suicidality in autistic adults

BackgroundWhile there are known risk factors for suicidality in autistic adults, these are often unconnected from theoretical frameworks that might explain why risk is elevated and guide clinical interventions. The present study investigated the relevance of constructs from the Interpersonal Theory of Suicide (ITS), including perceived burdensomeness, thwarted belongingness and acquired capability for suicide, and explored mechanisms through which certain risk factors (relationship status, age at diagnosis) might elevate suicide risk.MethodsAutistic adults (n = 314) completed an online study including measures of depression, anxiety and constructs from the ITS. Linear and multinomial regression analysis disentangled contributions of ITS variables from effects of depression and anxiety for past-year suicide ideation, past-year and lifetime suicide attempts. Mediation analyses examined associations between risk factors and these suicide outcomes via mechanisms proposed by the ITS.ResultsPast-year suicide ideation was associated with burdensomeness, mental rehearsal of suicide plans (a facet of acquired capability), and depression. Greater feelings of burdensomeness, and reduced fear of death, marked out participants who had attempted suicide in comparison to those who had experienced suicide ideation in the past year. Relationship status was indirectly associated with past-year suicide ideation via the mediators of depression and burdensomeness, and was associated with past-year attempts via its effect on ideation. Age at diagnosis was unrelated to any variables.LimitationsCross-sectional research is insensitive to causality and temporal dynamics, which is likely why interaction hypotheses from the ITS were unsupported. Normative measures may be invalid in autistic samples. There was no control group. The autistic sample was unrepresentative of the whole population, particularly autistic people with intellectual disabilities, ethnic/racial minorities, and gender minorities.ConclusionsPerceived burdensomeness and acquired capability appear potentially important to suicide in autistic people, and may mediate the effects of some risk factors. Future research should explore the temporal dynamics of suicide trajectories in longitudinal, prospective designs.

Factors associated with past-year attempts to quit e-cigarettes among current users: Findings from the Population Assessment of Tobacco and Health Wave 4 (2017–2018)

Over 10 million adults report use of electronic nicotine delivery systems (ENDS), with approximately 3.6 million reporting daily use. Even as the popularity of ENDS has increased, both as an available nicotine delivery system and an alternative to combustible cigarette smoking, few studies to date have examined ENDS cessation interest and related behaviors among ENDS users. The current study aimed to describe past year attempts to quit ENDS among current users and to investigate ENDS use / user characteristics associated with unsuccessful attempts to quit in the past year among adult, current, established ENDS users using data from the Population Assessment of Tobacco and Health (PATH) Study Wave 4. Over 10 % of ENDS users reported an attempt to quit completely in the past year, and 60 % indicated future intention to quit completely. Higher nicotine dependence, lower-frequency ENDS use, and higher interest in quitting were associated with past year attempts to quit ENDS. The current study adds support to claims that many ENDS users plan to quit using ENDS someday and highlights the need for continued research on ENDS cessation.

Association of the COVID-19 lockdown with smoking, drinking and attempts to quit in England: an analysis of 2019-20 data.

AimTo examine changes in smoking, drinking and quitting/reduction behaviour following the COVID‐19 lockdown in England.Design/settingMonthly cross‐sectional surveys representative of the adult population in England, aggregated before (April 2019–February 2020) versus after (April 2020) lockdown.ParticipantsA total of 20 558 adults (≥ 16 years).MeasurementsThe independent variable was the timing of the COVID‐19 lockdown (before versus after March 2020). Dependent variables were: prevalence of smoking and high‐risk drinking, past‐year cessation and quit attempts (among past‐year smokers), past‐year attempts to reduce alcohol consumption (among high‐risk drinkers) and use of evidence‐based (e.g. prescription medication/face‐to‐face behavioural support) and remote support [telephone support/websites/applications (apps)] for smoking cessation and alcohol reduction (among smokers/high‐risk drinkers who made a quit/reduction attempt). Covariates included age, sex, social grade, region and level of nicotine and alcohol dependence (as relevant).FindingsThe COVID‐19 lockdown was not associated with a significant change in smoking prevalence [17.0% (after) versus 15.9% (before), odds ratio (OR) = 1.09, 95% CI = 0.95–1.24], but was associated with increases in quit attempts [39.6 versus 29.1%, adjusted odds ratio (ORadj) = 1.56, 95% CI = 1.23–1.98], quit success (21.3 versus 13.9%, ORadj = 2.01, 95% CI = 1.22–3.33) and cessation (8.8 versus 4.1%, ORadj = 2.63, 95% CI = 1.69–4.09) among past‐year smokers. Among smokers who tried to quit, there was no significant change in use of evidence‐based support (50.0 versus 51.5%, ORadj = 1.10, 95% CI = 0.72–1.68) but use of remote support increased (10.9 versus 2.7%, ORadj = 3.59, 95% CI = 1.56–8.23). Lockdown was associated with increases in high‐risk drinking (38.3 versus 25.1%, OR = 1.85, CI = 1.67–2.06), but also alcohol reduction attempts by high‐risk drinkers (28.5 versus 15.3%, ORadj = 2.16, 95% CI = 1.77–2.64). Among high‐risk drinkers who made a reduction attempt, use of evidence‐based support decreased (1.2 versus 4.0%, ORadj = 0.23, 95% CI = 0.05–0.97) and there was no significant change in use of remote support (6.9 versus 6.1%, ORadj = 1.32, 95% CI = 0.64–2.75).ConclusionsFollowing the March 2020 COVID‐19 lockdown, smokers and high‐risk drinkers in England were more likely than before lockdown to report trying to quit smoking or reduce alcohol consumption and rates of smoking cessation and use of remote cessation support were higher. However, high‐risk drinking prevalence increased post‐lockdown and use of evidence‐based support for alcohol reduction by high‐risk drinkers decreased with no compensatory increase in use of remote support.

Suicide Attempts and Homelessness: Timing of Attempts Among Recently Homeless, Past Homeless, and Never Homeless Adults

Homelessness is associated with increased risk of suicide attempts. This study examined whether suicide attempts typically precede or occur during episodes of homelessness in a representative national sample. Data from 36,127 adults in the National Epidemiologic Survey on Alcohol and Related Conditions-III were used to identify 1,992 respondents who reported a lifetime suicide attempt. Bivariate analyses compared attempt histories between adults who reported past-year homelessness, homelessness prior to the past year, and no history of homelessness. Measures included years since most recent attempt and first attempt and proportion attempting suicide in the past year. Multivariable analyses adjusted for potentially confounding effects of age and identified independent factors associated with past-year attempts along with past-year homelessness. Among respondents who experienced homelessness in the past year, 21.0% reported a past-year suicide attempt, compared with 5.8% among those experiencing homelessness prior to the past year and 6.3% of those who were never homeless. However, the most recent attempt among those with past-year homelessness occurred 8.4 years previously, on average-3.8 years and 4.5 years more recently than among those experiencing homelessness prior to the past year and those who were never homeless, after age adjustment. Overall, first suicide attempts occurred 19.9 years previously, on average, with no significant group differences after age adjustment. Rates of past-year suicide attempts and past-year homelessness were strongly associated, suggesting that homelessness and suicidality strongly co-occur. However, among adults with recent homelessness and a suicide attempt history, suicidal behavior began decades ago and likely preceded homelessness.

Use of Electronic Cigarettes to Aid Long-Term Smoking Cessation in the United States: Prospective Evidence From the PATH Cohort Study.

Electronic cigarettes (e-cigarettes) are the preferred smoking-cessation aid in the United States; however, there is little evidence regarding long-term effectiveness among those who use them. We used the Population Assessment of Tobacco and Health Study to compare long-term abstinence between matched US smokers who tried to quit with and without use of e-cigarettes as a cessation aid. We identified a nationally representative cohort of 2,535 adult US smokers in 2014–2015 (baseline assessment), who, in 2015–2016 (exposure assessment), reported a past-year attempt to quit and the cessation aids used, and reported smoking status in 2016–2017 (outcome assessment; self-reported ≥12 months continuous abstinence). We used propensity-score methods to match each e-cigarette user with similar nonusers. Among US smokers who used e-cigarettes to help quit, 12.9% (95% confidence interval (CI): 9.1%, 16.7%) successfully attained long-term abstinence. However, there was no difference compared with matched non–e-cigarette users (cigarette abstinence difference: 2%; 95% CI: −3%, 7%). Furthermore, fewer e-cigarette users were abstinent from nicotine products in the long term (nicotine abstinence difference: −4%; 95% CI: −7%, −1%); approximately two-thirds of e-cigarette users who successfully quit smoking continued to use e-cigarettes. These results suggest e-cigarettes may not be an effective cessation aid for adult smokers and, instead, may contribute to continuing nicotine dependence.

Alternative flavored and unflavored tobacco product use and cigarette quit attempts among current smokers experiencing homelessness

IntroductionAlternative tobacco product (ATP) use is common in the general population; however, few studies have explored ATP among individuals experiencing homelessness. We recruited individuals experiencing homelessness who were current cigarette smokers to explore flavored and unflavored ATP use and its association with past-year cigarette quit attempts. MethodsUsing time-location sampling, we recruited participants from eight service sites in San Francisco, CA between December 2017 and July 2018. We explored type of ATP use and perceptions of product addiction, harm and risk between cigarette-only smokers and those who used cigarettes and ATPs (‘ATP users’). We used logistic regression to examine the association between ATP and past-year quit attempts, adjusting for demographics, substance use disorders, depressive symptoms, and cigarette use characteristics. ResultsAmong the 470 participants, 34.5% were cigarette-only users and 65.5% were ATP users. Among ATP users, 74.0% used cigars and 29.8% used e-cigarettes in the past month, with fruit-flavored products being the most common. ATP users were more likely to perceive cigars, blunts, and smokeless tobacco to be quite to extremely harmful or addictive compared to cigarette-only users. ATP use was not associated with past-year quit attempts, whereas hazardous alcohol use (OR = 2.07; CI 1.07–4.02) was associated with higher odds and and amphetamine use (OR = 0.50; CI 0.26–0.98) was associated with lower odds of past-year attempts. ConclusionsHigh rates of ATP use highlight a need for studies that explore motivations for use, beyond use as a smoking cessation aid, among people experiencing homelessness.

Towards the objective assessment of suicidal states: Some neurocognitive deficits may be temporally related to suicide attempt

Neurocognitive detection of suicidal states has the potential to significantly advance objective risk assessment. This goal requires establishing that neurocognitive deficits fluctuate around the time of a suicide attempt. The current study therefore evaluated whether neurocognitive performance is temporally related to suicide attempt, in a sample at highrisk for suicide (n = 141). Evaluations consisted of a clinician-administered interview, self-report questionnaires, and neurocognitive tasks assessing response inhibition, attentional control, and memory recognition. Analyses examined whether neurocognitive scores significantly differed according to the following temporal suicide attempt categories: (a) past-week attempt; (b) past-year attempt (not in past week); and (c) no past-year attempt. Univariate results showed that response inhibition and memory recognition were significantly related to suicide attempt recency. Post-hoc pairwise tests showed that participants with a past-week suicide attempt showed greater impairments than those without a past-year attempt. Multivariate tests showed the same pattern of results, adjusting for age, suicide attempts prior to past year, mood disturbance, and suicidal ideation. These results show that neurocognitive assessment of response inhibition and memory recognition shows sensitivity to the recency of a suicide attempt. While future prospective studies are needed, results suggest that phasic neurocognitive deficits may serve as objective markers of short-term suicide risk.

Recours à la psychothérapie en France chez les adultes avec tentative de suicide : résultats d’une vaste enquête épidémiologique

ObjectivesThe current study aims to identify the factors associated with the use of psychotherapy among adults with a history of suicide attempt. MethodsA large cross-sectional survey (N=22,138) was conducted in four regions of France to characterize mental health care needs in the general population. Data were collected between April and June 2005 by trained interviewers using a computer-assisted telephone interviewing system (CATI). Sociodemographics, past-year mental disorders, lifetime and 12-month history of suicide attempts, and use of psychotherapy were assessed. ResultsOverall, 7.1% of adults reported having undergone psychotherapy in the course of their life, and 2.0% in the previous 12 months. While 8.3% of adults with a lifetime suicide attempt (prior to the previous 12 months) underwent a psychotherapy in the previous 12 months, 27.5% of adults with a past-year suicide attempt underwent a psychotherapy in the previous 12 months. Psychotherapy was provided by psychiatrists (49.5%), psychologists (28.2%), and psychoanalysts (10.6%). While the frequency of psychotherapy sessions was greater among those with a prior attempt as compared to those with no prior attempt [Chi2 (10)=21.35, P=.019], there was no difference in therapy duration [Chi2 (8)=6.71, P=.568]. Compared to adults who did not report a prior attempt, those with a prior suicide attempt were 3,3 more likely to undergo psychotherapy with a psychologist [AOR=3.31 (2.54–4.31)]. Among adults with a prior suicide attempt, increased odds of undergoing a psychotherapy in the course of their life was predicted by higher education [AOR=2.81 (1.56–5.06)], living in the Paris region [AOR=2.06 (1.32–3.23)], and being a woman [AOR=1.50 (1.08–2.09)]. Increased odds of undergoing a psychotherapy in the previous 12 months was predicted by a major depressive disorder [AOR=2.59 (1.57–4.27)], any anxiety disorder [AOR=1.79 (1.07–2.97)], higher education [AOR=3.60 (1.29–10.0)], living in a city of 20,000 to 100,000 inhabitants [AOR=2.71 (1.13–6.50)] and more [AOR=2.50 (1.12–5.57)] (outside of the Paris region), a 2000 to 3000 euros monthly income [AOR=2.37 (1.15–4.85)]. DiscussionOne third of adults with a lifetime suicide attempt and close to half of those with a past-year attempt have received some form of psychotherapy in the course of their life. In line with prior work, higher education and income level predicted past-year use of psychotherapy among adults with a prior suicide attempt. These findings highlight the association between major depressive disorder or anxiety disorders and increased odds of undergoing psychotherapy in the previous 12 months among adults with prior attempt. While pharmacological treatment, inpatient hospitalizations for mental health problems, visits with a general practitioner or specialized physician are free of charge in France, psychotherapy provided by psychologists or psychotherapists is currently not covered by the French Social Security health care system. As the treatment of mental disorders plays an important role in the reduction of suicide risk, supporting evidence-based psychotherapy through its reimbursement appears to be an important public health issue.

The Association of Pain Intensity and Suicide Attempts Among Patients Initiating Pain Specialty Services

Using Veterans Health Administration data, we assessed the extent to which mean past-year (365 days) pain intensity scores were associated with suicide attempts in the year after the initiation of pain specialty services in fiscal years 2012 to 2014 (N = 221,817). Suicide attempts in the year after initiating Veterans Health Administration pain specialty services (ie, index visit) were identified using medical records and a suicide surveillance sources. Adjusted hazard models accounted for key covariates (eg, demographics, comorbidities). Subgroup analyses were also conducted on veterans without and with a suicide attempt in the year before the index visit to examine risk for first attempt and reattempts. Adjusted analyses revealed that pain intensity scores were significantly associated suicide attempts after the index visit. Specifically, veterans with severe and moderate pain had a hazards ratio of 1.41 (95% confidence interval = 1.21-1.63) and 1.29 (95% confidence interval = 1.13-1.47), respectively. These results were consistent for those without a past-year attempt and for those with a past-year attempt. The results suggest that moderate to severe pain intensity in the year before initiating pain specialty services may be a useful indicator of suicide risk, even when considered in the context of key factors. PerspectiveThis study used national administrative and suicide surveillance data to assess the relationship between pain intensity and suicide attempts after an initial visit for pain specialty services among veterans. These findings highlight the potential usefulness of assessing pain intensity as an indicator for suicide risk.

Exploring Cross-Sectional Predictors of Suicide Ideation, Attempt, and Risk in a Large Online Sample of Transgender and Gender Nonconforming Youth and Young Adults.

Rates of suicide ideation and attempt appear to be particularly high in the transgender and gender nonconforming (TGNC) population, yet little is known about which factors are the most salient contributors for TGNC young people and how these contributors vary across suicide-related outcomes. Within the largest sample of TGNC young people to date (N = 1896; ages 14-30), we examined the contribution of demographics (age, assigned sex, gender identity, sexual orientation identity, race/ethnicity, and socioeconomic status), minority stress (gender-related affirmation, gender-related self-concept, victimization, and gender-affirming medical treatment desire/access), social support (from family and friends), and depressive symptoms in the cross-sectional prediction of three suicide-related outcomes: past-year attempt, past-year ideation, and a composite measure of suicide risk. Each set of factors explained significant variance in each outcome; however, only several predictors remained significant in each of the full models. Gender-related victimization and depressive symptoms were independent predictors for all three outcomes. Additional predictors varied across outcome. Age, male identity, sexual orientation-based victimization, and friend support were associated with suicide attempt. Age, queer identity, gender-related self-concept negativity, and family support were associated with suicide ideation, and pansexual identity and gender-related self-concept negativity were associated with positive suicide risk screen. Prevention and intervention efforts aimed at building support and positive self-concept, decreasing victimization, and treating depression are likely to partially reduce suicide ideation and attempt in TGNC adolescents and young adults. Comprehensive interventions with younger adolescents are particularly critical.

Risk of Suicide Attempt Among Soldiers in Army Units With a History of Suicide Attempts

Mental health of soldiers is adversely affected by the death and injury of other unit members, but whether risk of suicide attempt is influenced by previous suicide attempts in a soldier's unit is unknown. To examine whether a soldier's risk of suicide attempt is influenced by previous suicide attempts in that soldier's unit. Using administrative data from the Army Study to Assess Risk and Resilience in Servicemembers (STARRS), this study identified person-month records for all active-duty, regular US Army, enlisted soldiers who attempted suicide from January 1, 2004, through December 31, 2009 (n = 9650), and an equal-probability sample of control person-months (n = 153 528). Data analysis was performed from August 8, 2016, to April 10, 2017. Logistic regression analyses examined the number of past-year suicide attempts in a soldier's unit as a predictor of subsequent suicide attempt, controlling for sociodemographic features, service-related characteristics, prior mental health diagnosis, and other unit variables, including suicide-, combat-, and unintentional injury-related unit deaths. The study also examined whether the influence of previous unit suicide attempts varied by military occupational specialty (MOS) and unit size. Of the final analytic sample of 9512 enlisted soldiers who attempted suicide and 151 526 control person-months, most were male (86.4%), 29 years or younger (68.4%), younger than 21 years when entering the army (62.2%), white (59.8%), high school educated (76.6%), and currently married (54.8%). In adjusted models, soldiers were more likely to attempt suicide if 1 or more suicide attempts occurred in their unit during the past year (odds ratios [ORs], 1.4-2.3; P < .001), with odds increasing as the number of unit attempts increased. The odds of suicide attempt among soldiers in a unit with 5 or more past-year attempts was more than twice that of soldiers in a unit with no previous attempts (OR, 2.3; 95% CI, 2.1-2.6). The association of previous unit suicide attempts with subsequent risk was significant whether soldiers had a combat arms MOS or other MOS (ORs, 1.4-2.3; P < .001) and regardless of unit size, with the highest risk among those in smaller units (1-40 soldiers) (ORs, 2.1-5.9; P < .001). The population-attributable risk proportion for 1 or more unit suicide attempts in the past year indicated that, if this risk could be reduced to no unit attempts, 18.2% of attempts would not occur. Risk of suicide attempt among soldiers increased as the number of past-year suicide attempts within their unit increased for combat arms and other MOSs and for units of any size but particularly for smaller units. Units with a history of suicide attempts may be important targets for preventive interventions.

Youth Tobacco Cessation

Despite declining use of conventional tobacco products, youth use of non-cigarette tobacco has become prevalent; however, quitting behaviors remain largely unexplored. To examine nationally representative data on quit intentions and past-year attempts to quit all tobacco use among current youth tobacco users. In 2013, data were analyzed from the 2012 National Youth Tobacco Survey (NYTS). Weighted prevalence estimates of quit intentions and past-year quit attempts for current youth tobacco users are presented. Prevalence of quit intentions and past-year attempts to quit all tobacco use were 52.8% and 51.5%, respectively, among current youth tobacco users. Among non-mutually exclusive groups, current cigarette smokers had the highest prevalence of quit intentions (56.8%) and past-year quit attempts (52.5%), whereas current hookah users had the lowest prevalence of quit intentions (41.5%) and past-year quit attempts (43.7%). Quit intentions among black, non-Hispanics (65.0%) and Hispanics (60.4%) were significantly higher versus white, non-Hispanics (47.5%). Youth reporting parental advice against tobacco had significantly higher prevalence of quit intentions (56.7%) and past-year quit attempts (55.0%) than those not reporting parental advice. Youth who agreed all tobacco products are dangerous (58.5%) had significantly higher prevalence of quit intentions than those who disagreed (37.0%). Continued efforts are needed to better understand youth motivation for quitting all tobacco products. Public health messaging about the dangers of all tobacco and cessation efforts should be aimed at the full range of tobacco products, not just cigarettes, and tailored to meet the needs of youth polytobacco users.
