    Moderators of treatment effects of a video-based cognitive-behavioral therapy for insomnia comorbid with cancer
    (Routledge, 2016-08-05) Savard, Josée; Savard, Marie-Hélène; Ivers, Hans
    Purpose: To assess the moderating role of demographic and clinical variables on the efficacy of a video-based cognitive behavioral therapy for insomnia (VCBT-I) among breast cancer patients. Patients and methods: As part of a randomized controlled trial, 80 women received VCBT-I. Results: Patients with a more advanced breast cancer were less likely to show reductions on the Insomnia Severity Index (ISI) and increased sleep efficiency at posttreatment. Patients using an antidepressant medication showed a larger reduction of ISI scores and a higher rate of insomnia remission. Remission of insomnia was also significantly more likely in individuals with a higher annual income. When using a multivariate binary classification tree analysis, the best and unique predictor of insomnia remission was having a less severe baseline ISI score. Conclusion: Although efficacious in general, VCBT-I does not appear to be an optimal format for everybody.

    A longitudinal examination of the interrelationships between multiple health behaviors in cancer patients
    (Wiley Online Library, 2019-05-27) Savard, Josée; Savard, Marie-Hélène; Bernard, Paquito; Ivers, Hans
    A healthy lifestyle following a cancer diagnosis is associated with reduced risk for a cancer recurrence. Better understanding the interrelationships between multiple health behaviors (HB) in cancer survivors could inform the development of more effective interventions to promote a healthy lifestyle. Methods: This prospective study assessed the longitudinal interrelationships between smoking, physical activity, alcohol intake, and caffeine consumption among patients with mixed cancer sites at the peri‐operative period and 2, 6, 10, 14, and 18 months later. A cross‐lagged design and structural equation modeling were used to assess the relationships between all four HBs over time. Results: The study included 962 participants. The model showed a good fit to the data. For all four HBs, continuity paths consistently indicated that one particular health behavior was significantly predicted by the same health behavior at the previous time point. However, no consistent pattern of cross‐lagged relationships between HBs emerged. Physical activity at 14‐ and 18‐month evaluations was the HB most consistently involved either as a predictor as a predicted variable. Conclusion: Overall, this study indicates that HBs assessed following cancer surgery are mostly independent and that interventions promoting HB changes during the cancer treatment trajectory need to target each health behavior separately.

    Sleep-wake difficulties in community-dwelling cancer patients receiving palliative care : subjective and objective assessment
    (Cambridge University Press, 2017-09-21) Bernatchez, Marie Solange; Savard, Josée; Savard, Marie-Hélène; Aubin, Michèle; Ivers, Hans
    Objective : Prevalence rates of sleep difficulties in advanced cancer patients have varied widely across studies (12 to 96%), and none of these employed a diagnostic interview to distinguish different types of sleep–wake disorders. Moreover, very limited information is available on subjective and objective sleep parameters in this population. Our study was conducted in palliative cancer patients and aimed to assess rates of sleep–wake disorders and subsyndromal symptoms and to document subjective and objective sleep–wake parameters across various types of sleep–wake difficulties. Method : The sample was composed of 51 community-dwelling cancer patients receiving palliative care and having an Eastern Cooperative Oncology Group score of 2 or 3. Relevant sections of the Duke Interview for Sleep Disorders were administered over the phone. An actigraphic recording and a daily sleep diary were completed for 7 consecutive days. Results : Overall, 68.6% of the sample had at least one type of sleep–wake difficulty (disorder or symptoms): 31.4% had insomnia and 29.4% had hypersomnolence as their main sleep–wake problem. Participants with insomnia as their main sleep difficulty had greater disruptions of subjective sleep parameters, while objectively-assessed sleep was more disrupted in patients with hypersomnolence comorbid with another sleep–wake difficulty. Significance of the Results : The high rates of sleep–wake difficulties found in this study indicate a need to screen more systematically for sleep–wake disorders, including insomnia and hypersomnolence, in both palliative care research and clinical practice, and to develop effective nonpharmacological interventions specifically adapted to this population.

    Insomnia, hypnotic use, and road collisions : a population-based, 5-year cohort study
    (American Sleep Disorders Association and Sleep Research Society, 2020-02-29) Mérette, Chantal; Morin, Charles M.; Savard, Josée; LeBlanc, Mélanie; Ivers, Hans
    Study Objectives The study objectives were to examine accidental risks associated with insomnia or hypnotic medications, and how these risk factors interact with sex and age. Methods A population-based sample of 3,413 adults (Mage = 49.0 years old; 61.5% female), with or without insomnia, were surveyed annually for five consecutive years about their sleep patterns, sleep medication usage, and road collisions. Results There was a significant risk of reporting road collisions associated with insomnia (hazard ratio [HR] = 1.20; 95% confidence interval [CI] = 1.00–1.45) and daytime fatigue (HR = 1.21; 95% CI = 1.01–1.47). Insomnia and its daytime consequences were perceived to have played some contributory role in 40% of the reported collisions. Both chronic (HR = 1.50; 95% CI = 1.17–1.91) and regular use of sleep medications (HR = 1.58; 95% CI = 1.16–2.14) were associated with higher accidental risks, as well as being young female with insomnia and reporting excessive daytime sleepiness. Conclusions Both insomnia and use of sleep medications are associated with significant risks of road collisions, possibly because of or in association with some of their residual daytime consequences (i.e. fatigue and poor concentration). The findings also highlight a new group of at-risk patients, i.e. young women reporting insomnia and excessive daytime sleepiness.

    Disruptions in sleep-wake cycles in community-dwelling cancer patients receiving palliative care and their correlates
    (Taylor & Francis, 2017-11-16) Bernatchez, Marie Solange; Savard, Josée; Ivers, Hans
    Significant disruptions in sleep–wake cycles have been found in advanced cancer patients in prior research. However, much remains to be known about specific sleep–wake cycle variables that are impaired in patients with a significantly altered performance status. More studies are also needed to explore the extent to which disrupted sleep–wake cycles are related to physical and psychological symptoms, time to death, maladaptive sleep behaviors, quality of life and 24-h light exposure. This study conducted in palliative cancer patients was aimed at characterizing patients’ sleep–wake cycles using various circadian parameters (i.e. amplitude, acrophase, mesor, up-mesor, down-mesor, rhythmicity coefficient). It also aimed to compare rest–activity rhythm variables of participants with a performance status of 2 vs. 3 on the Eastern Cooperative Oncology Group scale (ECOG) and to evaluate the relationships of sleep–wake cycle parameters with several possible correlates. The sample was composed of 55 community-dwelling cancer patients receiving palliative care with an ECOG of 2 or 3. Circadian parameters were assessed using an actigraphic device for seven consecutive 24-h periods. A light recording and a daily pain diary were completed for the same period. A battery of self-report scales was also administered. A dampened circadian rhythm, a low mean activity level, an early mean time of peak activity during the day, a late starting time of activity during the morning and an early time of decline of activity during the evening were observed. In addition, a less rhythmic sleep–wake cycle was associated with a shorter time to death (from the first home visit) and with a lower 24-h light exposure. Sleep–wake cycles are markedly disrupted in palliative cancer patients, especially, near the end of life. Effective non-pharmacological interventions are needed to improve patients’ circadian rhythms, including perhaps bright light therapy.

    Familial aggregation of insomnia
    (American Sleep Disorders Association and Sleep Research Society, etc, 2017-02-01) Mérette, Chantal; Morin, Charles M.; Rochefort, Amélie; Savard, Josée; Dauvilliers, Yves A.; Jarrin, Denise C.; LeBlanc, Mélanie; Ivers, Hans
    Study Objectives: There is little information about familial aggregation of insomnia; however, this type of information is important to (1) improve our understanding of insomnia risk factors and (2) to design more effective treatment and prevention programs. This study aimed to investigate evidence of familial aggregation of insomnia among first-degree relatives of probands with and without insomnia. Methods: Cases (n = 134) and controls (n = 145) enrolled in a larger epidemiological study were solicited to invite their first-degree relatives and spouses to complete a standardized sleep/insomnia survey. In total, 371 first-degree relatives (Mage = 51.9 years, SD = 18.0; 34.3% male) and 138 spouses (Mage = 55.5 years, SD = 12.2; 68.1% male) completed the survey assessing the nature, severity, and frequency of sleep disturbances. The dependent variable was insomnia in first-degree relatives and spouses. Familial aggregation was claimed if the risk of insomnia was significantly higher in the exposed (relatives of cases) compared to the unexposed cohort (relatives of controls). The risk of insomnia was also compared between spouses in the exposed (spouses of cases) and unexposed cohort (spouses of controls). Results: The risk of insomnia in exposed and unexposed biological relatives was 18.6% and 10.4%, respectively, yielding a relative risk (RR) of 1.80 (p = .04) after controlling for age and sex. The risk of insomnia in exposed and unexposed spouses was 9.1% and 4.2%, respectively; however, corresponding RR of 2.13 (p = .28) did not differ significantly. Conclusions: Results demonstrate evidence of strong familial aggregation of insomnia. Additional research is warranted to further clarify and disentangle the relative contribution of genetic and environmental factors in insomnia.

    Prevalence of insomnia and its treatment in Canada
    (Canadian Psychiatric Association, 2011-09-01) Mérette, Chantal; Morin, Charles M.; Bélanger, Lynda; Savard, Josée; LeBlanc, Mélanie; Ivers, Hans
    Objectives : To estimate the prevalence of insomnia and examine its correlates (for example, demographics and physical and mental health) and treatments. Methods : A sample of 2000 Canadians aged 18 years and older responded to a telephone survey about sleep, health, and the use of sleep-promoting products. Respondents with insomnia were identified using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, and the International Classification of Diseases, Tenth Edition, criteria. Results : Among the sample, 40.2% presented at least 1 symptom of insomnia (that is, trouble falling or staying asleep, or early morning awakening) for a minimum of 3 nights per week in the previous month, 19.8% were dissatisfied with their sleep, and 13.4% met all criteria for insomnia (that is, presence of 1 insomnia symptom 3 nights or more per week for at least 1 month, accompanied by distress or daytime impairment). Insomnia was associated with female sex, older age, and poorer self-rated physical and mental health. Thirteen per cent of respondents had consulted a health care provider for sleep difficulties once in their lifetime. Moreover, 10% had used prescribed medications for sleep in the previous year, 9.0% used natural products, 5.7% used over-the-counter products, and 4.6% used alcohol. There were differences between French- and English-speaking adults, with the former group presenting lower rates of insomnia (9.5%, compared with 14.3%) and consultation (8.7%, compared with 14.4%), but higher rates of prescribed medications (12.9%, compared with 9.3%) and the use of natural products (15.6%, compared with 7.4%). Conclusions : Insomnia is a prevalent condition, although few people seek professional consultation for this condition. Despite regional differences in the prevalence and treatments used to manage insomnia, prescribed medications remain the most widely used therapeutic option.

    Feasibility of a cognitive-behavioral and environmental intervention for sleep-wake difficulties in community-dwelling cancer patients receiving palliative care
    (International Society of Nurses in Cancer Care, 2018-12-06) Bernatchez, Marie Solange; Savard, Josée; Savard, Marie-Hélène; Aubin, Michèle
    BACKGROUND: High rates of sleep-wake difficulties have been found in patients with cancer receiving palliative care. Pharmacotherapy is the most frequently used treatment option to manage these difficulties despite numerous adverse effects and the absence of empirical evidence of its efficacy and innocuity in palliative care. OBJECTIVE: This pilot study aimed to assess the feasibility and acceptability of a cognitive-behavioral and environmental intervention (CBT-E) to improve insomnia and hypersomnolence in patients with a poor functioning level and to collect preliminary data on its effects. METHODS: Six patients with cancer receiving palliative care (Eastern Cooperative Oncology Group score 2-3), who had insomnia and/or hypersomnolence, received 1 CBT-E individual session at home. They applied the strategies for 3 weeks. Patients completed the Insomnia Severity Index, the Epworth Sleepiness Scale, a daily sleep diary, and a 24-hour actigraphic recording (7 days) at pretreatment and posttreatment, in addition to a semistructured interview (posttreatment). RESULTS: Participants found strategies easy to apply most of the time, and none was rated as impossible to use because of their health condition. However, their adherence and satisfaction toward CBT-E were highly variable. Results on the effects of CBT-E were heterogeneous, but improvements were observed in patients with a persistent insomnia disorder. CONCLUSIONS: The CBT-E protocol tested among this highly selected sample was fairly well received and suggested positive outcomes in some patients, particularly those with an insomnia complaint alone. IMPLICATIONS: Efforts should be pursued to adapt CBT-E and develop other nonpharmacological interventions, in order to provide an alternative to pharmacotherapy for sleep-wake difficulties in this population.

    Depression in the first year after traumatic brain injury
    (Neurotrauma Society, 2018-07-15) Laviolette, Valérie; Ouellet, Marie-Christine; Roy, Joanne.; Turgeon-Fournier, Alexis; Moore, Lynne; Savard, Josée; Swaine, Bonnie; Beaulieu-Bonneau, Simon.; Sirois, Marie-Josée; Giguère, Myriam
    The aims of this study were to document the frequency of major and minor depressive episodes in the first year after traumatic brain injury (TBI), taking into account TBI severity and pre-morbid history of major depression, and to describe trajectories of depressive episodes. Participants were 227 adults who were hospitalized post-TBI (76% male; mean age = 41 years; 50% mild, 33% moderate, and 17% severe TBI). Major and minor depressive episodes were assessed with the Mini International Neuropsychiatric Interview at three time points (4, 8, and 12 months after TBI). Overall, 29% of participants had a major depressive episode in at least one of the three assessments, with fairly stable rates across assessments. Participants with mild TBI were more likely than those with moderate/severe TBI to be diagnosed with major depression, as were individuals with a positive pre-morbid history of depression compared to those without such history. In addition, 13% of participants had a minor depressive episode in at least one of the three assessments. Rates of minor depression significantly decreased from 4 to 8–12 months post-injury. Results also revealed a wide variety of trajectories of depressive episodes across assessments. Of note, 52% of major depression cases still fulfilled diagnostic criteria 4 months later, whereas 38% of minor depression cases deteriorated to major depression at the following assessment. These findings suggest that depression is highly prevalent after TBI, and monitoring of patients with subthreshold depressive symptoms is warranted in order to prevent the development of full-blown major depressive episodes.

    A non-inferiority randomized controlled trial comparing a home-based aerobic exercise program to a self-administered cognitive-behavioral therapy for insomnia in cancer patients
    (Sleep Research Society, 2018-07-25) Mercier, Joanie; Savard, Josée; Ivers, Hans
    Study Objectives Thirty to sixty percent of cancer patients have insomnia symptoms, a condition which may lead to numerous negative consequences and for which an efficacious management is required. This randomized controlled trial aimed to assess the efficacy of a 6-week home-based aerobic exercise program (EX) compared to that of a 6-week self-administered cognitive-behavioral therapy for insomnia (CBT-I) to improve sleep in cancer patients. Method Forty-one patients (78.1% female, mean age 57 years) with various types of cancer and having insomnia symptoms (Insomnia Severity Index [ISI] score ≥ 8) were randomized to the EX (n = 20) or the CBT-I (n = 21) groups. Measures were completed at pretreatment and posttreatment, as well as at 3- and 6-month follow-ups. Results The EX intervention was statistically inferior to CBT-I in reducing ISI scores at posttreatment but was non-inferior at follow-up. However, no significant group-by-time interaction was found on any outcome and both interventions led to a significant improvement of subjectively-assessed sleep impairments on the ISI, the Pittsburgh Sleep Quality Index (PSQI) and most sleep parameters from a daily sleep diary at posttreatment corresponding to medium to large time effects (ds > 0.50 for ISI, PSQI, sleep onset latency, wake after sleep onset, total wake time and sleep efficiency). Conclusion Both interventions produced significant improvements of sleep. However, EX was found to be significantly inferior to CBT-I in reducing ISI scores at posttreatment, which contradicts the initial non-inferiority hypothesis. These findings suggest that CBT-I remains the treatment of choice for cancer-related insomnia, although EX can lead to some beneficial effects.
