Shorter communications: Exploring the impact of a brief smartphone-based alcohol intervention app (DrinksRation) on the quality of life of UK military veterans.

Alcohol misuse - defined as consuming more than 14 units of alcohol per week - is a well-established problem among veterans. This study investigated the change in quality of life among help-seeking UK veterans who completed a 28-day brief alcohol intervention delivered via a digital smartphone application (called DrinksRation) and have previously sought clinical help for a mental health disorder. This study was a secondary outcome analysis of data collected during a randomised control trial. In total, 123 UK veterans participated in the study and were randomly allocated to either the intervention or control arm. Participants completed self-report questionnaires regarding their alcohol use and quality of life (WHOQOL-BREF) at baseline, day 28 (end of intervention), day 84, and day 168. At the primary endpoint (day 84), we found significantly greater improvements in the intervention arm compared to the control arm for psychological quality of life (Cohen's d = 0.47), and environmental quality of life (d = 0.34). However, we observed no statistically significant differences between the intervention and control arm for social relationships and physical quality of life. Further, for day 168 we found no significant differences. Findings suggest that DrinksRation can increase quality of life among help-seeking veterans who have previously sought help for a mental health disorder, but the increases were modest and restricted to certain domains. Additional treatment may be needed for long-term and sustained improvements in quality of life.

Recruiting Military Veterans into Alcohol Misuse Research: The Role of Social Media and Facebook Advertising.

Background: The use of digital technology within health care service delivery, monitoring, and research is becoming progressively popular, particularly given the ongoing COVID-19 pandemic. Mobile health (m-health) apps, one form of digital technology, are increasingly being used to promote positive health related behavior change. Therefore, it is important to conduct research to understand the efficacy of m-health apps. The process of participant recruitment is an essential component in producing strong research evidence, along with ensuring an adequately powered sample to conduct meaningful analyses and draw robust conclusions. Methods: In this work we outline and reflect on the strategies used to recruit help-seeking military veterans into an intervention study, which aimed to evaluate the efficacy of an app (Drinks:Ration) to modify behavior in alcohol misusers. Recruitment strategies included through (1) partner organizations and (2) social media and Facebook advertising (ads). Results: Facebook ads were live for a period of 88 days and were viewed by a total audience of 29,416 people. In total 168 military veterans were recruited across all recruitment strategies, meaning that Drinks:Ration exceeded its recruitment targets. Half of the sample (n = 84) were recruited through social media, including Facebook ads. Conclusions: The current article highlighted that targeted Facebook ads were an efficient strategy to recruit military veterans into a digital intervention trial aiming to reduce alcohol consumption because they reduced the amount of time and resources required to contact a large number of potentially eligible individuals for our study. This article acts as a starting point for other researchers to evaluate their recruitment pathways for recruiting military veterans into alcohol misuse research.

Problem drinking recognition among UK military personnel: prevalence and associations.

PURPOSE: Despite the higher prevalence of problem drinking in the UK military compared to the general population, problem recognition appears to be low, and little is known about which groups are more likely to recognise a problem. This study examined prevalence of problem drinking recognition and its associations. METHODS: We analysed data from 6400 regular serving and ex-serving personnel, collected in phase 3 (2014-2016) of the King's Centre for Military Health Research cohort study. MEASUREMENTS: Participants provided sociodemographic, military, health and impairment, life experiences, problem drinking, and problem recognition information. Problem drinking was categorised as scores ≥ 16 in the AUDIT questionnaire. Associations with problem recognition were examined with weighted logistic regressions. FINDINGS: Among personnel meeting criteria for problem drinking, 49% recognised the problem. Recognition was most strongly associated (ORs ≥ 2.50) with experiencing probable PTSD (AOR = 2.86, 95% CI = 1.64-5.07), social impairment due to physical or mental health problems (AOR = 2.69, 95% CI = 1.51-4.79), adverse life events (AOR = 2.84, 95% CI = 1.70-4.75), ever being arrested (AOR = 2.99, CI = 1.43-6.25) and reporting symptoms of alcohol dependence (AOR = 3.68, 95% CI = 2.33-5.82). To a lesser extent, recognition was also statistically significantly associated with experiencing psychosomatic symptoms, feeling less healthy, probable common mental health disorders, and increased scores on the AUDIT. CONCLUSION: Half of UK military personnel experiencing problem drinking does not self-report their drinking behaviour as problematic. Greater problem drinking severity, poorer mental or physical health, and negative life experiences facilitate problem recognition.

The evolution of PTSD symptoms in serving and ex-serving personnel of the UK armed forces from 2004 to 16: A longitudinal examination.

Whilst most military personnel do not develop Post-Traumatic Stress Disorder (PTSD), ex-serving personnel exhibit higher levels compared to those in the military. The heterogeneity of symptom development for serving and ex-serving personnel has not yet been compared in the UK Armed Forces (UK AF). Latent class growth modelling was employed to estimate the trajectories of PTSD symptoms from three waves of data from the PTSD Checklist (PCL-C) from a UK AF sample (N = 7357). Regression mixture models were conducted to investigate covariates of class membership. Five trajectory classes were identified. Most of the sample reported no-low symptoms (71.3%). Of those reporting probable PTSD during the 12 year-period, 4.6% showed improvements, 4.9% worsened, and 1.8% displayed chronic symptoms. A class with subthreshold elevated symptoms (17.3%) was also identified. Trajectories of serving and ex-serving personnel were not substantially different, but more ex-serving personnel were symptomatic and those with chronic symptoms worsened over time. Chronic disorder was associated with lower rank, experiencing violent combat, and proximity to wounding/death on deployment. Worsening symptoms were associated with childhood stress/violence, lower rank, not being in a relationship, inconsistent post-deployment social support, proximity to wounding/death, and voluntary, or medical discharge. The present study found most UKAF personnel did not report PTSD symptoms between 2004 and 16 but, among those experiencing probable PTSD, more participants reported deteriorating/persistent symptoms than who improved. PTSD-onset was related to adversities across childhood and deployment, and lack of social support. Findings underscore the importance of addressing the through-life contributors of PTSD in order to prevent ingrained disorder.

Smartphone-based alcohol interventions: A systematic review on the role of notifications in changing behaviors toward alcohol.

Background: Smartphone-based interventions are increasingly being used to facilitate positive behavior change, including reducing alcohol consumption. However, less is known about the effects of notifications to support this change, including intervention engagement and adherence. The aim of this review was to assess the role of notifications in smartphone-based interventions designed to support, manage, or reduce alcohol consumption. Methods: Five electronic databases were searched to identify studies meeting inclusion criteria: (1) studies using a smartphone-based alcohol intervention, (2) the intervention used notifications, and (3) published between 1st January 2007 and 30th April 2021 in English. PROSPERO was searched to identify any completed, ongoing, or planned systematic reviews and meta-analyses of relevance. The reference lists of all included studies were searched. Results: Overall, 14 papers were identified, reporting on 10 different interventions. The strength of the evidence regarding the role and utility of notifications in changing behavior toward alcohol of the reviewed interventions was inconclusive. Only one study drew distinct conclusions about the relationships between notifications and app engagement, and notifications and behavior change. Conclusions: Although there are many smartphone-based interventions to support alcohol reduction, this review highlights a lack of evidence to support the use of notifications (such as push notifications, alerts, prompts, and nudges) used within smartphone interventions for alcohol management aiming to promote positive behavior change. Included studies were limited due to small sample sizes and insufficient follow-up. Evidence for the benefits of smartphone-based alcohol interventions remains promising, but the efficacy of using notifications, especially personalized notifications, within these interventions remain unproven.

Evaluating the Efficacy of the Drinks:Ration Mobile App to Reduce Alcohol Consumption in a Help-Seeking Military Veteran Population: Randomized Controlled Trial.

BACKGROUND: Alcohol misuse is higher in the UK armed forces (AF) than in the general population. Research demonstrates that alcohol misuse persists after an individual leaves service, and this is notably the case for those who are seeking help for a mental health difficulty. Despite this, there is no work on testing a mobile alcohol reduction intervention that is personalized to support the UK AF. OBJECTIVE: To address this gap, we investigated the efficacy of a 28-day brief alcohol intervention delivered via a mobile app in reducing weekly self-reported alcohol consumption among UK veterans seeking help for mental health difficulties. METHODS: We performed a 2-arm participant-blinded randomized controlled trial (RCT). We compared a mobile app that included interactive features designed to enhance participants' motivation and personalized messaging (intervention arm) with a version that provided government guidance on alcohol consumption only (control arm). Adults were eligible if they had served in the UK AF, were currently receiving or had received clinical support for mental health symptoms, and consumed 14 units (approximately 112 g of ethanol) or more of alcohol per week. Participants received the intervention or the control mobile app (1:1 ratio). The primary outcome was a change in self-reported weekly alcohol consumption between baseline and day 84 assessed using the validated Timeline Follow Back for Alcohol Consumption (TLFB) (prior 7 days), with a secondary outcome exploring self-reported change in the Alcohol Use Disorder Identification Test (AUDIT) score. RESULTS: Between October 2020 and April 2021, 2708 individuals were invited to take part, of which 2531 (93.5%) did not respond, 54 (2%) were ineligible, and 123 (4.5%) responded and were randomly allocated (62, 50.4%, intervention; 61, 49.6%, control). At day 84, 41 (66.1%) participants in the intervention arm and 37 (60.7%) in the control arm completed the primary outcome assessment. Between baseline and day 84, weekly alcohol consumption reduced by -10.5 (95% CI -19.5 to -1.5) units in the control arm and -28.2 (95% CI -36.9 to -19.5) units in the intervention arm (P=.003, Cohen d=0.35). We also found a significant reduction in the AUDIT score of -3.9 (95% CI -6.2 to -1.6) in the intervention arm (Cohen d=0.48). Our primary and secondary effects did not persist over the longer term (day 168). Two adverse events were detected during the trial. CONCLUSIONS: This study examined the efficacy of a fully automated 28-day brief alcohol intervention delivered via a mobile app in a help-seeking sample of UK veterans with hazardous alcohol consumption. We found that participants receiving Drinks:Ration reduced their alcohol consumption more than participants receiving guidance only (at day 84). In the short term, we found Drinks:Ration is efficacious in reducing alcohol consumption in help-seeking veterans. TRIAL REGISTRATION: ClinicalTrials.gov NCT04494594; https://tinyurl.com/34em6n9f.

Prevalence of at-risk drinking recognition: A systematic review and meta-analysis.

BACKGROUND: There is a prominent "treatment gap" in relation to at-risk drinking (ARD), whereby a minority of at-risk drinkers ever access treatment. Research suggests that recognition of problem drinking is a necessary precursor for help-seeking and treatment. OBJECTIVE: This systematic review and meta-analysis aimed to estimate the prevalence of ARD recognition within those meeting criteria for ARD. METHOD: PsycINFO, Web of Science, Scopus, and MEDLINE were searched using the terms: problem* AND (recogni* OR perceive* OR perception OR self-identif*) AND alcohol - to identify studies published in English between 2000 and 2022. Studies reported the frequency (weighted or unweighted) of participants meeting ARD criteria that also directly identified ARD, perceived a need for help, or endorsed a readiness to change. The prevalence of ARD recognition was estimated using a random-effects meta-analysis with 95% confidence intervals (CIs). RESULTS: 17 studies were included which provided data for 33,349 participants with ARD. Most (n = 14) were US studies. ARD was self-identified via a single indicator in 7 studies, whereas recognition was assessed via stages of change in 4 studies and need for help in 6 studies. The pooled prevalence of ARD recognition was 31% (95% CI: 25%-36%), and subgroup analyses indicated alcohol use severity, measure of recognition, and population type to be significant sources of heterogeneity. CONCLUSIONS: Most individuals with ARD fail to recognise their drinking problem so preventive approaches that promote recognition may be helpful. However, we must be cautious of how inconsistency in question framing affects self-reported problem recognition.

Cost of post-deployment screening for mental illness in the UK military: findings from a cluster randomised controlled trial.

BACKGROUND: Little is known about the economic impact of military mental health screening. AIMS: To investigate (a) whether post-deployment screening of military personnel affects use and cost of services and (b) the impact of psychiatric morbidity on costs. METHODS: Participants were recruited from UK Royal Marine and Army platoons and randomised to an intervention group (which received tailored advice predicated upon mental health status) or a control group (which received general advice following assessment of mental health status). The intervention costs were calculated while service use and associated costs were assessed at 12-month follow-up. RESULTS: Data were available for 6323 participants. Mean screening cost was £34. Service costs were slightly higher in the control group compared to the intervention group (£1197 vs. £1147) which was not statistically significant (bootstrapped 95%CI, -£363 to £434. In both groups, screening and control, costs were significantly higher for those who screened positive for mental health problems. CONCLUSIONS: Costs were not affected by screening. In countries that have already implemented post-deployment screening, the political cost of disinvestment needs careful consideration. Those who develop psychiatric morbidity have substantially higher care costs than those who do not.

Trajectories of alcohol misuse among the UK Armed Forces over a 12-year period.

AIM: To identify the main trajectories of alcohol misuse among UK military personnel from 12 years after the start of the Iraq war (2003) and the factors associated with each trajectory. DESIGN: Longitudinal cohort study with three phases of data collection (2004-06, 2007-09 and 2014-16). SETTING: United Kingdom. PARTICIPANTS: Serving and ex-serving personnel of the UK Armed Forces (n = 7111) participating at Phase 1 and at least one follow-up phase of the King's Centre for Military Health Research (KCMHR) cohort study. MEASUREMENTS: Trajectories of alcohol misuse were derived from scores using the Alcohol Use Disorders Identification Test (AUDIT-10) over three data collection phases. Demographic and military characteristics were collected and, among the key covariates, post-traumatic stress disorder (PTSD) was measured using the PTSD checklist (PCL-C) and childhood interpersonal stress and violence was measured using items from the Adverse Childhood Experiences questionnaire. FINDINGS: Five trajectories of alcohol misuse were identified, including 'no misuse' (n = 2249, 31.6%) and 'hazardous' (n = 3398, 47.8%), 'harmful' (n = 832, 11.7%), 'severe-to-hazardous' (n = 258, 5.3%) and 'severe' (n = 374, 3.6%) drinking. Substantial changes were evident only among severe drinkers, where more than half reduced over the study period. The factors most strongly associated with belonging to harmful/severe drinking classes were young age, male gender and childhood adversities and antisocial behaviour. Severe drinkers at Phase 1 were more likely to report probable PTSD and shorter military careers and were less likely to serve as Officers. Persistent severe drinkers were less likely to serve in the RAF compared to the Army and were more likely to be reserves. Not misusing alcohol was also associated with reserve status and having left service. CONCLUSIONS: In a cohort of approximately 7000 UK military personnel, trajectories of alcohol misuse appeared stable between 2004 and 2016. More than half of severe drinkers made substantial improvements over the period, but 68% of the cohort continued to drink hazardously or harmfully. Lack of change for the majority of the sample signals the need for strategies to address alcohol misuse and its cultural and psychosocial drivers.

Contribution of mental ill health during military service to postservice benefit claims in the UK.

OBJECTIVES: While most UK military personnel transition successfully into civilian life, some experience unemployment and disability, which may be partly attributable to in-service factors. This study aims to determine the degree to which in-service mental health problems impact on postservice benefit claims. METHODS: Using data from a cohort of 5598 recent leavers from regular service in the UK Armed Forces linked with data from the Department for Work and Pensions, we assessed associations between in-service mental health and postservice benefit claims, and the population attributable fraction (PAF) of benefit claims related to in-service mental health. An analysis with postservice mental ill health as mediator was performed to determine the degree to which the observed effects were a consequence of persistent illness, as opposed to remitted. RESULTS: Mental illness occurring in-service predicted both unemployment and disability claims, partly mediated by postservice health (23%-52% total effects mediated), but alcohol misuse did not. Common mental disorder (CMD) (PAF 0.07, 95% CI: 0.02 to 0.11) and probable post-traumatic stress disorder (PTSD) (PAF 0.05, 95% CI 0.01 to 0.09) contributed to unemployment claims. Probable PTSD was the largest contributor to disability claims (PAF 0.25, 95% CI 0.13 to 0.36), with a smaller contribution from CMD (PAF 0.16, 95% CI 0.03 to 0.27). CONCLUSIONS: In-service mental ill health gives rise to benefit claims. These effects are only partly mediated by postservice mental health, implying that in-service (or pre-service) mental issues have carry-over effects into civilian life even if remitted. Better prevention and treatment of in-service PTSD symptoms may well reduce postservice disability claims.

Evaluating the Efficacy of a Mobile App (Drinks:Ration) and Personalized Text and Push Messaging to Reduce Alcohol Consumption in a Veteran Population: Protocol for a Randomized Controlled Trial.

BACKGROUND: Alcohol misuse is higher in the UK Armed Forces than in the general population. Previous research has shown that interventions delivered via smartphones are efficacious in promoting self-monitoring of alcohol use, have utility in reducing alcohol consumption, and have a broad reach. OBJECTIVE: This single-blinded randomized controlled trial (RCT) aims to assess the efficacy of a 28-day brief alcohol intervention delivered via a smartphone app (Drinks:Ration) in reducing weekly self-reported alcohol consumption between baseline and 3-month follow-up among veterans who drink at a hazardous or harmful level and receive or have received support for mental health symptoms in a clinical setting. METHODS: In this two-arm, single-blinded RCT, a smartphone app that includes interactive features designed to enhance participants' motivation and personalized messaging is compared with a smartphone app that provides only government guidance on alcohol consumption. The trial will be conducted in a veteran population that has sought help through Combat Stress, a UK veteran's mental health charity. Recruitment, consent, and data collection will be carried out automatically through the Drinks:Ration platform. The primary outcome is the change in self-reported weekly alcohol consumption between baseline (day 0) and 3-month follow-up (day 84) as measured using the Time-Line Follow back for Alcohol Consumption. Secondary outcome measures include (1) change in the baseline to 3-month follow-up (day 84) Alcohol Use Disorder Identification Test score and (2) change in the baseline to 3-month follow-up (day 84) World Health Organization Quality of Life-BREF score to assess the quality of adjusted life years. Process evaluation measures include (1) app use and (2) usability ratings as measured by the mHealth App Usability Questionnaire. The primary and secondary outcomes will also be reassessed at the 6-month follow-up (day 168) to assess the longer-term benefits of the intervention, which will be reported as a secondary outcome. RESULTS: The study will begin recruitment in October 2020 and is expected to require 12 months to complete. The study results will be published in 2022. CONCLUSIONS: This study assesses whether a smartphone app is efficacious in reducing self-reported alcohol consumption in a veteran population that has sought help through Combat Stress using personalized messaging and interactive features. This innovative approach, if successful, may provide a means to deliver a low-cost health promotion program that has the potential to reach large groups, in particular those who are geographically dispersed, such as military personnel.

Long-Term Correlates of Mild Traumatic Brain Injury on Postconcussion Symptoms After Deployment to Iraq and Afghanistan in the UK Military.

OBJECTIVES: We assessed whether mild traumatic brain injury (mTBI) reported by UK service personnel between 2007 and 2009 was associated with postconcussion symptoms (PCS) 7 to 8 years later. SETTING: United Kingdom. PARTICIPANTS: A total of 4601 service personnel all of whom had deployed to Iraq and/or Afghanistan. DESIGN: Longitudinal study. MAIN OUTCOME MEASURES: Nine PCS reported in a survey carried out between 2014 and 2016. The main independent variable was mTBI reported between 2007 and 2009. RESULTS: A total of 2318 (50.4%) out of 4601 participants completed the follow-up questionnaire. Mild traumatic brain injury was associated with 2 of 9 PCS. Mild traumatic brain injury at baseline was associated with dizziness at follow-up in the fully adjusted model, in comparison with either "other injury" or "no injury" group. Mild traumatic brain injury was associated with loss of concentration in comparison with "no injury" but in comparison with the "other injury" group, it was not in the fully adjusted model. The prevalence of 7 of the 9 PCS increased over time regardless of mTBI status. CONCLUSIONS: Mild traumatic brain injury reported in 2007-2009 was associated with dizziness and possibly with loss of concentration 7 years later but not with most PCS. The prevalence of most PCS increased over time independently of mTBI.

Unemployment and benefit claims by UK veterans in the new millennium: results from a record linkage study.

OBJECTIVES: In the first study of its kind in the UK, we linked pensions data on benefit claims with data from the King's Military Cohort to assess uptake of unemployment and disability benefits in military veterans of the UK Armed Forces. METHODS: Benefits data were matched with data on the mental health, demographics and military-related variables for 7942 veterans who had previously served as regulars and transitioned to civilian life between 2003 and 2016. Associations between demographic and service-related factors and benefit claims were assessed using Cox regression to take into account period at risk. RESULTS: Around 20% of veterans claim unemployment benefits (UB) shortly after leaving, but this proportion drops rapidly to around 2% in the first 2 years post service. Receipt of disability benefits (DB) is less common (1.5%), but longer-term. The most consistent predictors of postservice benefit usage were: low rank (a proxy for socio-economic status while in service) (HR 1.42 (95% CI 1.23 to 1.65) for UB and 1.59 (95% CI 1.11 to 2.27) for DB); leaving service (HR 1.29 (95% CI 1.07 to 1.56) between unplanned leaving and UB, and 7.51 (95% CI 5.31 to 10.6) between medical discharge and DB), and having a history of claiming benefits before joining the Services (HR 1.62 (95% CI 1.34 to 1.95) between preservice and postservice UB, and 2.86 (95% CI 1.09 to 7.47) between preservice and postservice DB). CONCLUSIONS: Benefit claims by veterans are largely driven by socioeconomic, rather than military, factors. Additional employment-focused support to Service leavers may be particularly useful to lower-ranked personnel and those leaving in an unplanned way. Continuity of care and medical oversight is a key concern for those with medical discharges.

A Qualitative Evaluation of the Acceptability of a Tailored Smartphone Alcohol Intervention for a Military Population: Information About Drinking for Ex-Serving Personnel (InDEx) App.

BACKGROUND: Alcohol consumption in the UK Armed Forces is higher than in the general population, and this pattern continues after leaving the service. Smartphone apps may be useful to increase ex-serving personnel's awareness of their alcohol consumption, support self-monitoring, and prompt a change in behavior. OBJECTIVE: The study aimed to explore the acceptability of Information about Drinking in Ex-serving personnel (InDEx), a tailored smartphone app, combined with personalized short message service (SMS) text messaging designed to target ex-serving personnel who meet the criteria for hazardous alcohol use. METHODS: The InDEx intervention included 4 key modules: (1) assessment and normative feedback, (2) self-monitoring and feedback, (3) goal setting and review, and (4) personalized SMS text messaging. A semistructured telephone interview study was conducted with ex-serving personnel after using the app for a 28-day period. Interviews were used to explore the acceptability of app modules and its functionality and the perceived changes in participant's drinking. Interview transcripts were analyzed using inductive thematic analysis. RESULTS: Overall, 94% (29/31) participants who used InDEx agreed to take part in a telephone interview. Overall, 4 themes were identified: Credibility, Meeting their needs, Simplicity, and Helpful for ex-serving personnel. The importance of credibility, functionality, and meeting the individual needs of ex-serving personnel was emphasized. Acceptability and engagement with specific modules of the app and text messages were influenced by the following: (1) if they felt it provided credible information, (2) whether the content was appropriately personalized to them, (3) the ease of use, and (4) beliefs about their own drinking behaviors. Participants recommended that the app would be most suitable for personnel about to leave the Armed Forces. CONCLUSIONS: InDEx was an acceptable smartphone app for ex-serving personnel for monitoring alcohol consumption and in providing meaningful feedback to the individual. Pages that met the participant's interests and provided real time personalized, credible feedback on their drinking and text messages tailored to participant's interactions with the app were particularly favored.

Do serving and ex-serving personnel of the UK armed forces seek help for perceived stress, emotional or mental health problems?

Background: UK armed forces personnel are at risk of occupational psychological injury; they are often reluctant to seek help for such problems. Objective: We aimed to examine and describe sources of support, prevalence and associates of help-seeking among UK serving and ex-serving personnel. Method: A total of 1450 participants who self-reported a stress, emotional or mental health problem in the past 3 years were sampled from a health and wellbeing study and subsequently completed a telephone interview comprising measures of mental disorder symptoms, alcohol misuse and help-seeking behaviour. Results: Seven per cent of participants had not sought any help, 55% had accessed medical sources of support (general practitioner or mental health specialist), 46% had received formal non-medical (welfare) support and 86% had used informal support. Gender, age, perceived health, functional impairment, social support, deployment, alcohol and comorbidity impacted upon the choice of help source. Conclusions: This study found that the majority of those with perceived mental health problems sought some form of help, with over half using formal medical sources of support.

Antecedentes: El personal de las Fuerzas Armadas del Reino Unido está en riesgo de sufrir alteraciones psicológicas ocupacionales; a menudo son reacios a buscar ayuda para tales problemas. Objetivo: El objetivo fue examinar y describir las fuentes de apoyo, la prevalencia y los asociados de búsqueda de ayuda entre el personal de servicio y ex personal de servicio del Reino Unido. Método: En un estudio de salud y bienestar se tomaron muestras de 1.450 participantes que informaron sobre un problema de estrés, de salud mental o emocional en los últimos tres años y posteriormente completaron una entrevista telefónica que incluía medidas de síntomas de trastornos mentales, abuso de alcohol y conductas de búsqueda de ayuda. Resultados: El 7% de los participantes no había buscado ninguna ayuda. El 55% accedió a fuentes médicas de apoyo (médico general o especialista en salud mental), el 46% recibió apoyo formal no médico (servicio social) y el 86% utilizó apoyo informal. El sexo, la edad, la salud percibida, el deterioro funcional, el apoyo social, el despliegue, el alcohol y la comorbilidad se ven afectados por la elección de la fuente de ayuda. Conclusiones: Este estudio encontró que la mayoría de las personas con problemas de salud mental percibidos buscaron algún tipo de ayuda, y más de la mitad usaron fuentes médicas formales de apoyo.

Fourteen-year trajectories of posttraumatic stress disorder (PTSD) symptoms in UK military personnel, and associated risk factors.

The aim of this study was to examine trajectories of posttraumatic stress disorder (PTSD) symptoms over a 14-year period and the risk factors associated with each trajectory. 1885 UK military personnel provided information at four time points since 2002. The PTSD Check list-Civilian Version (PCL-C) was used at all time points. Growth mixture models (GMM) were estimated to examine whether individuals could be clustered into discrete groups with similar trajectories. Multinomial logistic regressions were carried out to investigate factors associated with class membership. The three-class GMM was the most parsimonious solution. This included 90.2% in the resilient class, 4.1% in the improving class and 5.7% in the deteriorating class. Both the deteriorating and improving classes were associated with childhood adversity (odds ratios (OR) 3.9 (95% CI 2.3, 6.7) and 3.3 (95% CI 2.1, 5.0) respectively) and antisocial behaviour (OR 2.8 (95% CI 1.9, 4.2) and 3.7 (95% CI 2.4, 5.8) respectively), alcohol misuse (OR 3.5 (95% CI 2.4, 5.1) and 3.3 (95% CI 2.1, 5.2) respectively) and longer time since leaving Service in comparison to the resilient group. Those in the youngest group and those in a combat role (OR 0.32, 95% CI 0.19, 0.54) were more likely to belong to the deteriorating class. 10% of the cohort had symptoms of PTSD; of those, up to half were symptomatic for most of the follow-up period. Those whose score improved did not reach the low scores of the resilient group. Younger age and combat role were associated with worse prognosis of PTSD.

Mental health outcomes at the end of the British involvement in the Iraq and Afghanistan conflicts: a cohort study.

BACKGROUND: Little is known about the prevalence of mental health outcomes in UK personnel at the end of the British involvement in the Iraq and Afghanistan conflicts.AimsWe examined the prevalence of mental disorders and alcohol misuse, whether this differed between serving and ex-serving regular personnel and by deployment status. METHOD: This is the third phase of a military cohort study (2014-2016; n = 8093). The sample was based on participants from previous phases (2004-2006 and 2007-2009) and a new randomly selected sample of those who had joined the UK armed forces since 2009. RESULTS: The prevalence was 6.2% for probable post-traumatic stress disorder, 21.9% for common mental disorders and 10.0% for alcohol misuse. Deployment to Iraq or Afghanistan and a combat role during deployment were associated with significantly worse mental health outcomes and alcohol misuse in ex-serving regular personnel but not in currently serving regular personnel. CONCLUSIONS: The findings highlight an increasing prevalence of post-traumatic stress disorder and a lowering prevalence of alcohol misuse compared with our previous findings and stresses the importance of continued surveillance during service and beyond.

A Smartphone App and Personalized Text Messaging Framework (InDEx) to Monitor and Reduce Alcohol Use in Ex-Serving Personnel: Development and Feasibility Study.

BACKGROUND: Self-reported alcohol misuse remains high in armed forces personnel even after they have left service. More than 50% of ex-serving personnel meet the criteria for hazardous alcohol use; however, many fail to acknowledge that they have a problem. Previous research indicates that interventions delivered via smartphone apps are suitable in promoting self-monitoring of alcohol use, have a broad reach, and may be more cost-effective than other types of brief interventions. There is currently no such intervention specifically designed for the armed forces. OBJECTIVE: This study sought to describe the development of a tailored smartphone app and personalized text messaging (short message service, SMS) framework and to test the usability and feasibility (measured and reported as user engagement) of this app in a hard-to-engage ex-serving population. METHODS: App development used Agile methodology (an incremental, iterative approach used in software development) and was informed by behavior change theory, participant feedback, and focus groups. Participants were recruited between May 2017 and June 2017 from an existing United Kingdom longitudinal military health and well-being cohort study, prescreened for eligibility, and directed to download either Android or iOS versions of the "Information about Drinking for Ex-serving personnel" (InDEx) app. Through the app, participants were asked to record alcohol consumption, complete a range of self-report measures, and set goals using implementation intentions (if-then plans). Alongside the app, participants received daily automated personalized text messages (SMS) corresponding to specific behavior change techniques with content informed by the health action process approach with the intended purpose of promoting the use of the drinks diary, suggesting alternative behaviors, and providing feedback on goals setting. RESULTS: Invitations to take part in the study were sent to ex-serving personnel, 22.6% (31/137) of whom accepted and downloaded the app. Participants opened the InDEx app a median of 15.0 (interquartile range [IQR] 8.5-19.0) times during the 4 week period (28 days), received an average of 36.1 (SD 3.2) text messages (SMS), consumed alcohol on a median of 13.0 (IQR 11.0-15.0) days, and consumed a median of 5.6 (IQR 3.3-11.8) units per drinking day in the first week, which decreased to 4.7 (IQR 2.0-6.9) units by the last week and remained active for 4.0 (IQR 3.0-4.0) weeks. CONCLUSIONS: Personnel engaged and used the app regularly as demonstrated by the number of initializations, interactions, and time spent using InDEx. Future research is needed to evaluate the engagement with and efficacy of InDEx for the reduction of alcohol consumption and binge drinking in an armed forces population.
