abstract = "AIM: Existing literature links poor sleep and anxiety symptoms in
adolescents. This pilot study aimed to develop a practical method
through which a program to improve sleep could reach adolescents
in need and to examine the feasibility of a mindfulness-based,
multi-component group sleep intervention using sleep and anxiety
as outcome measures. METHODS: Sixty-two grade 9 students (aged
13-15) at a girls' school were screened with the Pittsburgh Sleep
Quality Index (PSQI) and Spence Children's Anxiety Scale (SCAS).
Ten participants with self-reported poor sleep were enrolled into
a six-session program based on Bootzin \& Stevens, with added
stress/anxiety-specific components. Sessions covered key aspects
of basic mindfulness concepts and practice, sleep hygiene, sleep
scheduling, evening/daytime habits, stimulus control, skills for
bedtime worries and healthy attitudes to sleep. Treatment changes
were measured by pre-post scores on the PSQI, SCAS and 7-day
actigraphy-measured sleep. RESULTS: The program demonstrated high
acceptability, with a completion rate of 90\%. Based on
effect-size analysis, participants showed significant improvement
on objective sleep onset latency (SOL), sleep efficiency and
total sleep time; actigraphy data also showed significantly
earlier bedtime, rise time and smaller day-to-day bedtime
variation. Post-intervention global PSQI scores were
significantly lower than that of pre-intervention, with
significant improvement in subjective SOL, sleep quality and
sleep-related daytime dysfunction. There were small improvements
on some subscales of the SCAS, but change on its total score was
minimal. CONCLUSIONS: A mindfulness-based, multi-component,
in-school group sleep intervention following brief screening is
feasible, and has the potential to improve sleep. Its impact on
anxiety needs further investigation.",

title = "Self-compassion weakens the association between hot flushes and
night sweats and daily life functioning and depression",
author = "Brown, Lydia and Bryant, Christina and Brown, Valerie M and Bei,
Bei and Judd, Fiona K",
abstract = "OBJECTIVES: Some women find hot flushes and night sweats (HFNS)
to interfere more in daily life and mood than others.
Psychological resources may help to explain these individual
differences. The aim of this study was to investigate the role of
self-compassion, defined as healthy way of relating toward the
self when dealing with difficult experiences, as a potential
moderator of the relationship between HFNS and daily life
activities, which in turn influences symptoms of depression.
STUDY DESIGN: This was a cross-sectional study using
questionnaire data from 206 women aged 40-60 who were currently
experiencing hot flushes and/or night sweats. Path analysis was
used to model relationships among menopausal factors (HFNS
frequency and daily interference ratings), self-compassion and
mood. MAIN OUTCOME MEASURE: Hot flush interference in daily
activities and depressive symptoms. RESULTS: On average, women
experienced 4.02 HFNS per day, and HFNS frequency was moderately
correlated with interference ratings (r=0.38). In the path
analytic model, self-compassion made significant direct
contribution to hot flush interference ratings ($\beta$=-0.37)
and symptoms of depression ($\beta$=-0.42), and higher
self-compassion was associated with lower interference and
depressive symptoms. Self-compassion also moderated the
relationship between HFNS frequency and hot flush interference.
Higher self-compassion was associated with weaker effects of HFNS
frequency on daily interference. CONCLUSIONS: Self-compassion may
weaken the association between HFNS and daily life functioning,
which in turn, could lead to less HFNS-related mood problems.
These findings imply that self-compassion may be a resilience
factor to help women manage hot flushes and night sweats.",

in adolescents",

abstract = "School-related sleep restriction in adolescents has been
identified by studies comparing weekday and weekend sleep. This
study compared weekday and vacation sleep to assess restricted
and extended sleep opportunities. One-hundred and forty-six
adolescents (47.3\% male) aged 16.2 $\pm$ 1.0 years (M $\pm$ SD)
from the general community wore an actigraph continuously for 4
weeks: the last week of a school term (Time-E), the following
2-week vacation, and the first week of the next term.
Self-reported sleep was assessed for each of the three time
intervals, and chronotype was assessed using the
Morningness-Eveningness Questionnaire at Time-E. Daily actigraphy
bedtime, rise-time, time-in-bed, total sleep time, sleep onset
latency, sleep efficiency, and \% wake after sleep onset were
analysed using latent growth curve modelling. The removal of
school-related sleep restriction was associated with an abrupt
delay in sleep timing and increase in sleep duration.
Subsequently, bedtime and rise-time showed further linear delays
throughout the vacation, while changes in time-in-bed were
non-significant. Sleep onset latency increased linearly, peaking
in the middle of the second vacation week. Across the first
vacation week, total sleep time and sleep efficiency linearly
decreased, while \% wake after sleep onset increased. These
changes stabilized during the second vacation week. Older age and
eveningness were associated with later bedtime and rise-time,
whilst females had longer time-in-bed, total sleep time and sleep
onset latency. Compared with school days, sleep during the
vacation was characterized by later timing, longer duration,
lower quality and greater variability. Recovery from
school-related sleep restriction appeared to be completed within
the 2 weeks of naturalistic extended sleep.",

for analyzing intra-individual variability, particularly
when variability is treated as a predictor. In the present
article, we first reviewed methods of analyzing
intra-individual variability as an outcome, including the
individual standard deviation (ISD) and some recent methods.
We then introduced a novel Bayesian method for analyzing
intra-individual variability as a predictor. To make this
method easily accessible to the research community, we
developed an open source R package, VARIAN. To compare the
accuracy of parameter estimates using the proposed Bayesian
analysis against the ISD as a predictor in a regression, we
carried out a simulation study. We then demonstrated, using
empirical data, how the estimated intra-individual
variability derived from the proposed Bayesian analysis can
be used to answer the following two questions: (1) is
intra-individual variability in daily time-in-bed associated
with subjective sleep quality? (2) does subjective sleep
quality mediate the association between time-in-bed
variability and depressive symptoms? We concluded with a
discussion of methodological and practical considerations
that can help guide researchers in choosing methods for
evaluating intra-individual variability.",

abstract = "STUDY OBJECTIVES: School terms and vacations represent naturally
occurring periods of restricted and extended sleep opportunities.
A cognitive model of the relationships among objective sleep,
subjective sleep, and negative mood was tested across these
periods, with sleep-specific (i.e., dysfunctional beliefs and
attitudes about sleep) and global (i.e., dysfunctional attitudes)
cognitive vulnerabilities as moderators. DESIGN: Longitudinal
study over the last week of a school term (Time-E), the following
2-w vacation (Time-V), and the first week of the next term
(Time-S). SETTING: General community. PARTICIPANTS: 146
adolescents, 47.3\% male, mean age =16.2 years (standard
deviation +/- 1 year). INTERVENTIONS: N/A. MEASUREMENTS AND
RESULTS: Objective sleep was measured continuously by actigraphy.
Sociodemographics and cognitive vulnerabilities were assessed at
Time-E; subjective sleep, negative mood (anxiety and depressive
symptoms), and academic stress were measured at each time point.
Controlling for academic stress and sex, subjective sleep quality
mediated the relationship between objective sleep and negative
mood at all time points. During extended (Time-V), but not
restricted (Time-E and Time-S) sleep opportunity, this mediation
was moderated by global cognitive vulnerability, with the
indirect effects stronger with higher vulnerability. Further, at
Time-E and Time-V, but not Time-S, greater sleep-specific and
global cognitive vulnerabilities were associated with poorer
subjective sleep quality and mood, respectively. CONCLUSIONS:
Results highlighted the importance of subjective sleep perception
in the development of sleep related mood problems, and supported
the role of cognitive vulnerabilities as potential mechanisms in
the relationships between objective sleep, subjective sleep, and
negative mood. Adolescents with higher cognitive vulnerability
are more susceptible to perceived poor sleep and sleep related
mood problems. These findings have practical implications for
interventions.",

title = "Sleep, mood, and cognitive vulnerability in adolescents: a
naturalistic study over restricted and extended sleep
opportunities",
author = "Bei, Bei",
abstract = "Introduction: It is well established that for adolescents, school
days are associated with sleep restriction, and that insufficient
sleep has been linked to mood disturbances. This longitudinal
study assessed sleep, mood, and life stress over the school term
and vacation periods with restricted and extended sleep
opportunities. The relationships between objective and subjective
sleep, as well as between sleep and mood were examined. A
cognitive model was proposed and tested to assess whether
sleep-specific (i.e., dysfunctional beliefs and attitudes about
sleep) and global (i.e., dysfunctional attitudes) cognitive
vulnerabilities played a role in these relationships. Methods:
One-hundred and forty-six adolescents (47.3\% male) aged
16.2+/-1.0 years (M+/-SD) from the general community wore an
actigraph continuously for four weeks: the last week of a school
term (Time-E), the following two-week vacation (Time-V), and the
first week of the next term (Time-S). Social demographic
information, chronotype, and cognitive vulnerabilities were
assessed at Time-E. Subjective sleep, symptoms of depression,
anxiety, and life stress were repeatedly measured at Time-E,
Time-V, Time-S, and the middle of the subsequent school term.
Regression analyses were used to explore the relationship between
sleep and mood, and structural equation modelling was used to
examine changes of variables over time, as well as the moderating
roles of cognitive vulnerabilities. Results: Compared with school
days, sleep during the vacation was characterized by later
timing, longer duration, lower quality and greater variability.
Daily changes in actigraphy- measured sleep over the vacation
period showed linear delays in sleep timing throughout the
vacation, while changes in time-in-bed were non-significant. The
first vacation week was characterized by a linear decrease in
total sleep time and sleep quality, and these changes stabilized
during the second vacation week. Compared to vacations, school
terms were associated with higher symptoms of depression,
anxiety, and life stress. Poorer sleep quality, particularly
poorer subjective perception of sleep quality, was significantly
associated with higher symptoms of depression and anxiety. Sleep-
specific cognitive vulnerability moderated the relationship
between objective and subjective sleep onset latency during
extended but not restricted sleep opportunity. After controlling
for life stress, global cognitive vulnerability played different
moderating roles in the relationship between subjective sleep and
mood over school term and vacation periods. Higher global
cognitive vulnerability was associated with a stronger
relationship between subjective sleep and symptoms of anxiety
(but not depression) during the school term, as well as with a
stronger relationship between subjective sleep and symptoms of
depression (but not anxiety) during the vacation period.
Conclusion: Sleep, mood, and life stress changed markedly over
the school term and vacation periods. Changes in sleep over the
vacation suggested that the recovery from school- related sleep
restriction was completed within two weeks' extended sleep
opportunity, and the average sleep duration over this period
suggested that sleep requirements in adolescence may be less than
conventionally described in the media and in the scientific
literature. Cognitive vulnerabilities played important roles in
the relationship between sleep and mood. Adolescents with higher
cognitive vulnerability might be more emotionally vulnerable
towards school-related sleep restriction. These findings have
important implications for future studies, as well as practical
implications for policies and interventions designed to improve
adolescents' wellbeing.",

well-being: An exploratory path analysis",

abstract = "OBJECTIVES: A large body of work has investigated the
relationship between menopausal factors and negative well-being
(e.g. anxiety and depressive symptoms), but less is known about
positive well-being and its correlates among midlife women. This
study tests two models with both positive and negative well-being
indices as outcomes: the first included menopausal factors as
predictors; the second model expanded the first by adding
self-compassion, a protective trait, as a predictor and
moderator. STUDY DESIGN: Cross-sectional study based on
self-report questionnaires from 206 women aged 40-60, currently
experiencing hot flushes. MAIN OUTCOME MEASURES: Hot flush
interference ratings, emotional balance, satisfaction with life,
eudaimonic well-being and depressive symptoms. RESULTS: In model
one, menopausal stage and hot flush frequency were independent of
well-being outcomes. Beliefs about perceived control over
menopause was the strongest predictor of well-being ($\beta$
range: .22-.32), followed by hot flush interference ratings
($\beta$ range: .15-.33). In model two, self-compassion was the
strongest predictor of well-being indices ($\beta$ range:
.20-.39), followed by beliefs about control ($\beta$ range:
.16-.20) and interference ratings ($\beta$ range: .17-.26).
CONCLUSIONS: Psychological aspects of the menopause appear more
strongly linked to well-being than physiological aspects such as
menopausal stage and hot flush frequency. Specifically,
self-compassion, feeling in control of menopause and low
interference ratings are three factors that are associated with
well-being among midlife women. These aspects could be considered
in tandem, as a means to support well-being in the context of
menopause.",

relationship early on in life is potentially important for the
prevention of cardiovascular disease (CVD). This study
investigated whether clinical depression is associated with
multiple physiological markers of CVD risk in adolescents from
the general community. METHODS: Participants aged 12-18 years
were recruited from the general community and screened for
depressive symptoms. Individuals with high and low depressive
symptoms were administered a diagnostic interview. Fifty
participants, 25 with a current depressive episode and 25 matched
healthy controls, subsequently completed cardiovascular
assessments. Variables assessed were automatic brachial and
continuous beat-to-beat finger arterial blood pressure, heart
rate, vascular functioning by pulse amplitude tonometry following
reactive hyperaemia and pulse transit time (PTT) at rest. Blood
samples were collected to measure cholesterol, glucose and
glycohaemoglobin levels and an index of cumulative risk of
traditional cardiovascular risk factors was calculated. RESULTS:
Depressed adolescents had a significantly lower reactive
hyperaemia index and shorter PTT, suggesting deterioration in
vascular integrity and structure. Higher fasting glucose and
triglyceride levels were also observed in the depressed group,
who also had higher cumulative risk scores indicative of
increased engagement in unhealthy behaviours and higher
probability of advanced atherosclerotic lesions. LIMITATIONS: The
sample size and number of males who completed all cardiovascular
measures was small. CONCLUSIONS: Clinically depressed adolescents
had poorer vascular functioning and increased CVD risk compared
to controls, highlighting the need for early identification and
intervention for the prevention of CVD in depressed youth.",

Correlates most consistently associated with greater IIV in one

non-White race/ethnicity, living alone, physical health
conditions, higher body mass index, weight gain, bipolar and
unipolar depression symptomatology, stress, and evening

with higher sleep/wake IIV, which was reduced following sleep
interventions. The effects of experimentally reduced sleep/wake
IIV on daytime functioning were inconclusive. In extending

Adolescents engaged in a variety of behaviors before bed.
Notably, playing video games was associated with significantly
later school and vacation BT and shorter school sleep duration
(controlling for chronotype). During vacation, online social
media was associated with significantly longer sleep onset
latency, and this relationship was mediated by higher PSAcog. In
contrast, on school nights, spending time with family was
associated with significantly earlier BT and longer sleep
duration. CONCLUSIONS: Technology-related PBBs video games and
online social media were risk factors for shorter and poorer
sleep, whereas time with family was protective of sleep
duration. In addressing sleep problems in adolescents,
therapeutic procedures that target the potentially addictive
nature of technology use and reduce PSAcog were implicated.",

on women's self report, findings from objectively measured sleep
have been mixed. Observational and intervention studies on the
relationship between sleep and women's psychological well-being
suggest that underlying causes of sleep disturbance across a
woman's lifespan are often multi-factorial. Comprehensive
assessments and targeted interventions are needed in managing
sleep problems in women. Cognitive behavioural interventions have
been shown to reduce sleep complaints during the perinatal and
menopausal periods, and improvements in sleep are likely to lead
to improvements in women's overall well-being.",

title = "Relationship of Psychosocial Resources With Allostatic Load: A
Systematic Review",
author = "Wiley, Joshua F and Bei, Bei and Bower, Julienne E and Stanton,
Annette L",
abstract = "OBJECTIVE: Allostatic load (AL) represents cumulative
wear-and-tear on the body and is operationalized as a multisystem
index of biomarkers. Allostatic load is associated with
morbidities and mortality, leading to a growing body of
literature that uses AL as an outcome in its own right.
Psychosocial resources (PSRs), such as mastery and social
support, may influence health outcomes in part via AL, and the
current review seeks to characterize the relations between PSRs
and AL. METHODS: A systematic review was conducted by searching
PubMed, CINAHL Plus, PsycINFO, Scopus, and Embase for studies
examining the relation between PSR(s) and AL in humans. From
1,417 abstracts screened, 60 full-text articles were reviewed,
and 24 studies met inclusion criteria. RESULTS: Mixed evidence
exists for a relationship between PSRs and AL. Most (14/24)
studies used a cross-sectional design, and only one study
investigated whether a PSR predicted change in AL. Compared to
cross-sectional studies, longitudinal studies were more likely to
report a significant relationship (8/14 versus 8/10,
respectively). Studies with statistically significant main or
moderated effects had larger sample sizes than those reporting
null effects. Whether a study reported a significant main or
moderated relationship did not differ by whether psychological
(8/11) or social (10/16) resources were assessed. CONCLUSIONS:
Evidence for a relationship between PSRs and AL is equivocal, and
obtained significant relationships are generally small in
magnitude. Gaps in the current literature and directions for
future research are discussed. Longitudinal studies are needed
that repeatedly assess PSRs and AL.",

vacation. Hassles were strongly associated with more negative
mood at all times. Our findings suggest significant fluctuations
in adolescent mood and everyday hassles across school-vacation
cycles. These findings call for careful consideration and
reporting of timing in mood and stress assessment in adolescent
research, as school-vacation cycles may have strong influence on
both. Naturalistic changes in mood over school-vacation cycles
reported are also clinically informative for designing and

title = "Better Objective Sleep Quality in Older Adults with High
Subjective Memory Decline",
author = "Cavuoto, Marina G and Ong, Ben and Pike, Kerryn E and Nicholas,
Christian L and Bei, Bei and Kinsella, Glynda J",
abstract = "BACKGROUND: Sleep disturbance is implicated in memory function
across normal aging and neurodegenerative disease. Furthermore,
there is mounting evidence to suggest that high levels of
subjective memory decline (SMD) may signal very early
neurodegenerative changes associated with Alzheimer's disease
(AD). This view prompts research examining the relationship
between SMD and other risk factors for cognitive decline,
including sleep disturbance. OBJECTIVE: To determine whether
objective and subjective indices of sleep predict SMD in older
adults. METHODS: 181 community-based older adults were divided
into groups of high and low SMD based on their responses to the
Memory Assessment Complaint Questionnaire (MAC-Q). They
undertook two weeks of objective sleep monitoring (actigraphy),
and completed a subjective sleep quality assessment using the
Pittsburgh Sleep Quality Index. RESULTS: Hierarchical logistic
regression indicated that after controlling for demographics and
mood, objective sleep quality predicted high SMD group status
($\Delta$Nagelkerke R2 = 0.07, $\chi$2 = 9.80 (3), p = 0.020),
while subjective sleep quality did not. Contrary to expectation,
however, less sleep disruption predicted high SMD. CONCLUSION:
These unexpected results may suggest a non-linear trajectory
between sleep and memory decline in aging. The findings are
discussed in relation to previous research, which taken
together, may indicate compensatory sleep patterns of reduced
sleep disruption in people with high levels of SMD. These
preliminary findings suggest the utility of including analysis
of sleep behavior in further longitudinal research of this
at-risk group of older people.",

title = "Dietary disinhibition mediates the relationship between poor
sleep quality and body weight",
author = "Blumfield, Michelle L and Bei, Bei and Zimberg, Iona Z and Cain,
Sean W",
abstract = "BACKGROUND: Inadequate sleep independently influences eating
habits and weight status. However, the relationship between these
three factors has not been well quantified. The objective of this
study was to examine if eating behavior (i.e. dietary restraint,
disinhibition and hunger) mediates the relationship between sleep
and body mass index (BMI) in a large sample of American adults.
METHOD: Cross-sectional data from the Nathan Kline Institute
Rockland sample were assessed (n = 602; 38.9 $\pm$ 14.5 years).
Self-reported sleep and eating behavior were measured using the
Pittsburgh Sleep Quality Index and Three Factor Eating
Questionnaire, respectively. Path analysis was used to examine
relationships amongst the construct, with mediation tested via
bootstrapped confidence intervals. RESULTS: Poorer sleep quality
was associated with both greater hunger (P = 0.03) and higher
disinhibited eating (overeating in the presence of palatable
foods or other disinhibiting stimuli like emotional stress; P <
0.001) behaviors. Higher disinhibited eating behavior was also
associated with higher BMI (P < 0.001). There was a significant
indirect relationship between sleep quality and BMI via
disinhibition (b [95\% CI] = 0.13 [0.06, 0.21], P = 0.001). No
significant effects were found when total sleep time or time in
bed were replaced as predictors in the mediation model.
CONCLUSION: Disinhibited eating behavior mediated the
relationship between sleep quality and weight status in both
males and females. This mediation was due to aspects of sleep
quality other than duration. These results suggest that improving
sleep quality may benefit weight loss by helping to reduce an
individuals' susceptibility to overeating.",
