A phenomenological inquiry into the costs and consequences of insomnia for veterans with serious mental illness.

Many individuals with serious mental illness (i.e. schizophrenia spectrum, bipolar or major depressive disorders, with serious functional impairments) have insomnia symptoms. Insomnia is a common reason for mental health referrals in the Veterans Health Administration. The primary aim of this study was to explore the costs (what participants lose or what trade-offs they make due to insomnia) and consequences (how insomnia impacts functioning) of insomnia for veterans with serious mental illness. Semi-structured interviews of 20 veterans with insomnia and serious mental illness were collected as data using an inductive phenomenological approach. Two main themes were identified: Sleep Affects Mental Health and Functioning; and Compromising to Cope. Results illuminate pathways by which sleep effort destabilizes functional recovery, and illustrate how sleep has multiplicative positive impacts on functioning and mood. Researchers and clinicians alike must explore supporting people with serious mental illness in replacing sleep effort with the recovery of meaningful identity-driven, values-based experiences formerly conceded due to serious mental illness, insomnia or both.

How do US military veterans with serious mental illness manage insomnia? A phenomenological analysis.

Insomnia is a prevalent experience for individuals with serious mental illness, and is one of the most common reasons for mental health referrals in the Veterans Health Administration. Insomnia also critically impacts psychiatric, cognitive and somatic outcomes. However, there is limited information about how people with serious mental illness (i.e. schizophrenia spectrum, bipolar, or major depressive disorders, with serious functional impairments) understand and respond to problems with their own sleep. Bringing this information to light will yield novel methods of research and treatment. The purpose of this study was to examine reactions to insomnia among veterans with serious mental illness and insomnia. An inductive phenomenological approach was used to collect data from 20 veterans with serious mental illness and insomnia using semi-structured interviews. Six themes were identified: Becoming Aware that Insomnia is a Problem; Response to and Dissatisfaction with Medications; Strategies to Get Better Sleep: Contrary to Usual Guidelines; Personal Responsibility for Getting Sleep; Resigned and Giving Up; and Acceptance and Persistence. These results provide insight into the process of identifying insomnia and the subsequent cognitive and behavioural responses that are used to manage sleep disturbances among veterans with serious mental illness, a group often excluded from gold-standard treatments for chronic insomnia. Clinical implications and recommendations for improving treatment efficacy are discussed.

A phenomenological inquiry into the experience of sleep: Perspectives of US military veterans with insomnia and serious mental illness.

The majority of people with serious mental illness experience insomnia, and insomnia is one of the most frequent reasons for mental health referrals in the Veterans Health Administration. Insomnia also represents a critical obstacle to mental health recovery. Little is known about how military veterans with mental health problems conceptualize their sleep and sleep problems; such information may uncover new avenues for research and treatment. Therefore, the purpose of this study was to explore how veterans with serious mental illness and insomnia experience and understand their sleep, towards the aim of identifying these new avenues. Participants included 20 veterans with insomnia and serious mental illness (i.e. schizophrenia spectrum, bipolar or major depressive disorders, with serious functional impairments). Data were collected via an inductive phenomenological approach using semi-structured interviews. We identified five themes: Sleep to Recharge; Sleep as a Fight; Sleep as Safety or Escape; Sleep as Dangerous; and Military Influence. Participants' relationship with sleep was complex; many associated it with intrusive and troubling hallucinations, paranoia and military experiences, yet at the same time desired sleep for its potential to liberate them from distress. Military mindsets both helped and hindered sleep. These results extend existing models of insomnia development and maintenance, and illuminate phenomena previously unidentified in this underserved veteran population. Clinical and theoretical implications are discussed, as well as new research directions for enhancing therapeutic efficacy.

Prior night sleep duration is associated with psychomotor vigilance in a healthy sample of police academy recruits.

Aviation, military, police, and health care personnel have been particularly interested in the operational impact of sleep restriction and work schedules given the potential severe consequences of making fatigue-related errors. Most studies examining the impact of sleep loss or circadian manipulations have been conducted in controlled laboratory settings using small sample sizes. This study examined whether the relationship between prior night sleep duration and performance on the psychomotor vigilance task could be reliably detected in a field study of healthy police academy recruits. Subjects (N = 189) were medically and psychiatrically healthy. Sleep-wake activity was assessed with wrist actigraphy for 7 days. Subjects performed the psychomotor vigilance task (PVT) for 5 min on a personal digital assistant (PDA) device before and after their police academy workday and on comparable times during their days off. Mixed-effects logistic regression was used to estimate the probability of having > or =1 lapse on the PVT as a function of the previous night sleep duration during the 7 days of field testing. Valid estimates of sleep duration were obtained for 1082 nights of sleep. The probability of a lapse decreased by 3.5%/h sleep the night prior to testing. The overall probability of having a lapse decreased by 0.9%/h since awakening, holding hours of sleep constant. Perceived stress was not associated with sleep duration or probability of performance lapse. These findings demonstrate the feasibility of detecting sleep and circadian effects on cognitive performance in large field studies. These findings have implications regarding the daytime functioning of police officers.
