Abstract Objective: Insomnia is a common health complaint among the elderly. Sleep problems in this group are often
accompanied by maladaptive sleep-related cognitions. However the relationship between dysfunctional beliefs and attitudes
about sleep to insomnia and depression in the elderly has not been explored in this environment. Methods: It was a cross
sectional study carried out among 212 elderly persons in the community. Individuals with a past history of mental illness were
excluded. Respondents were administered the Dysfunctional Beliefs and Attitudes about Sleep Questionnaire (DBAS-16),
Insomnia Severity Index (ISI) questionnaire, the Geriatric Depression Scale (GDS). Results: The mean age of respondents
were 70.1±7.1 years, 81.6% were males, 23.6% used medication to aid sleep, while 16.0% slept for < 4 hours per night.
Insomnia and depressive symptoms were present in 53.3% and 23.6% of the respondents respectively. Presence of insomnia
(t = 5.19, df = 210, p < 0.001), depressive symptomatology (t = 2.52, df =210, p = 0.013) and use of medication to aid sleep
(t = 2.436, df = 210, p = 0.016) was significantly associated higher total DBAS scores. The multiple linear regression showed
that the presence of insomnia (p < 0.001, ß = 21.93) was the most significant predictor variable of dysfunctional beliefs and
attitude about sleep. Conclusions: Faulty sleep beliefs are present among the elderly in Nigeria and may be driven by poor
sleep. The clinical implication is that these cognitions should be identified and modified in the management of insomnia in
this age group.

1. Introduction
1.1. Background
Insomnia is a common health complaint among elderly
people. It has been estimated to affect between 25-30% of
the older population [1, 2]. The diagnostic and statistical
manual of mental disorders, 5th Edition, defines insomnia as
a predominant complaint of dissatisfaction with sleep
quantity or quality, along with difficulty initiating or
maintaining sleep, which causes clinically significant
distress or impairment in important areas of functioning (i.e.,
social, occupational, behavioral, etc.) [3]. Negative
consequences of insomnia in late life include decreased
quality of life, high risk for heart diseases, high risk of falls,
increased psychological difficulties, increased economic and
social costs, increase use and abuse of tranquilizers and
mortality [4].
Often sleep problems in the older age groups are
precipitated and maintained by maladaptive sleep-related

cognitions (e.g., faulty beliefs and appraisals, unrealistic
expectations and perceptual bias) [5, 6]. Dysfunctional
beliefs associated with worry about the negative
consequences of insomnia and hopelessness about the fear of
losing control over sleep have been identified as the most
critical factors in differentiating chronic insomnia from
transient insomnia [7]. These dysfunctional sleep-related
cognitions may be influenced by the presence of physical
and psychological disorders such as chronic pain and mood
disorders [8, 9]. The importance of targeting sleep-related
beliefs and attitudes in the treatment of insomnia is
highlighted by the fact that more adaptive beliefs and
attitudes about sleep following treatment are associated with
better maintenance of sleep improvements at follow-ups [6,
10].
1.2. Rationale
Previous studies on sleep disorders have been conducted
among the elderly population in Nigeria [2, 11, 12]. But
these were largely limited to profile and prevalence studies.
Despite increasing recognition of the importance of
cognitive factors in the etiology of insomnia, no past work
has investigated the dysfunctional sleep related beliefs and
attitudes among the elderly population in this country. This
study will fill this dearth of information.
