PURPOSE:   The purpose of this review was to describe psychological and social factors associated with low back pain that could be applied in spine care programs in medically underserved areas and low- and middle-income countries.
METHODS:
  We performed a narrative review of cohort, cross-sectional, qualitative and mixed methods studies investigating adults with low back pain using Medline and PubMed were searched from January 2000 to June 2015. Eligible studies had at least one of the following outcomes: psychological, social, psychosocial, or cultural/ethnicity factors. Studies met the following criteria: (1) English language, (2) published in peer-reviewed journal, (3) adults with spinal disorders, (4) included treatment, symptom management or prevention.
RESULTS:   Out of 58 studies, 29 were included in this review. There are few studies that have evaluated psychological and social factors associated with back pain in low- and middle-income communities, therefore, adapting recommendations from other regions may be needed until further studies can be achieved.
CONCLUSION:   Psychological and social factors are important components to addressing low back pain and health care providers play an important role in empowering patients to take control of their spinal health outcomes. Patients should be included in negotiating their spinal treatment and establishing treatment goals through careful listening, reassurance, and information providing by the health care provider. Instruments need to be developed for people with low literacy in medically underserved areas and low- and middle-income countries, especially where psychological and social factors may be difficult to detect and are poorly addressed.

Introduction
For most of the twentieth century, spinal pain was assumed
to be like other diseases in that symptoms were related
to documentable spinal pathology. [1–3] This assumption
implied that pain and disability were related directly to
pathology severity [4, 5] and that interventions directed
at the pathology would result in resolution of pain and
disability. Toward the end of the century, research showed
that changes noted on imaging and other diagnostic tests
were not necessarily correlated with the degree of symptoms and disability. [6, 7] A growing body of research has
shown that social and psychological factors contribute to
spine pain and disability. [8]
The relationship among chronic pain, psychological,
and social factors may be addressed using a biopsychosocial perspective of pain. [9, 10] This perspective requires
a comprehensive conceptualization of pain, including
sensory, afective, and cognitive dimensions, shifting the
framework from biomedical pain relief to a biopsychosocial model. [11, 12] The somatic basis of pain is included
in the biopsychosocial model, whether or not the cause
is identifed. When pain becomes chronic, non-physical
factors become increasingly important and the interaction
between psychological, social, and physical traits must be
considered in concert.
People who have musculoskeletal disorders may have
psychological and social risk factors for developing persistent pain and long-term disability. [13–16] The concept
of psychosocial “flags” were frst introduced in the 1990s
and have evolved over time. [16, 17] “Yellow flags” are
obvious psychological risk factors related to back pain that
are considered normal but unhelpful (e.g., pain behaviors,
emotional responses). Psychological risk factors include an
individual’s emotional, cognitive and behavioral responses
to pain and the ability to distinguish between pain and
disability. [15]
Factors include:
(1) depression, catastrophizing, anxiety, and stress,
(2) beliefs and attitudes about back pain,
(3) function, coping abilities, and
(4) anticipation that passive treatments instead of active participation
will help.
Psychological factors have been conceptualized as maladaptive psychological responses to pain [15]
including maladaptive pain coping behaviors, anxiety, and
depression as salient risk factors for the development of
persistent back pain. [15, 18]
“Orange flags” are those
psychological factors may be related to musculoskeletal
symptoms but that are considered abnormal (e.g., posttraumatic stress disorder, major depression). “Blue flags”
are social and environmental/workplace perceptions (e.g.,
stressful environment) and “black flags” are factors related
to the nature of the work environment (e.g., heavy work
without being allowed to modify, infuence from health
care providers, family or legislative issues). Thus, social
risk factors [19, 20] in general include the individual’s
perception of the social environment, including: poor work
satisfaction, unsupportive work environment, work stress,
and compensation issues. [13–15]
Psychological and social factors can act as barriers to
recovery and their risks are increased when more than one is
present. [13, 15, 18, 21–25] Each of the “flags” infuences a
patient’s response to care, and therefore, may need diferent
assessment and interventions. Thus, it is essential that clinicians are able to diferentiate one fag from another.
Identifying these factors may help clinicians identify
which patients are more at risk of developing persistent pain
and disability. These factors may inform decision-making
and treatment outcomes [26] and are predictors of outcomes
of clinical interventions. Addressing some factors through
various cognitive/behavioral interventions has the potential
to reduce disability associated with spine pain. [27–30]
World Spine Care [31] developed an initiative, the Global
Spine Care Initiative (GSCI), which includes biopsychosocial concepts in the model of care, thus incorporates psychological and social factors.
The goals of this narrative review were to:
(1) provide an overview of psychological and social factors related to low back pain,
(2) list the psychological and social factors that may infuence common interventions, and
(3) describe assessments and interventions for psychological and social factors that could be considered in a care
pathway for underserved communities.
Discussion
Psychological and social factors are important for the development and prognosis of spinal pain and disability. These
factors also infuence a person’s decision to seek health care,
demand extensive investigation, consider themselves disabled, stop working, fle for disability, or fle a legal claim. [13–15, 51–55] However, such options are not available
everywhere. These behaviors may amplify the efect of psychological risk factors by reinforcing pain symptoms. It is,
therefore, crucial that clinicians assess patients with spine
pain and disability for commonly associated psychological and social factors. [75] When psychosocial risk factors
have been identifed, each issue should be addressed with
an appropriate intervention. These may include: education,
patient reassurance, advice to stay active, early return to
activity, as well as cognitive behavioral therapy and multidisciplinary rehabilitation where available. [15, 18, 24, 25,
28, 29, 32–35, 53, 57, 71, 76]
Instruments to investigate psychological and social factors
Psychological and social factors may be difcult to detect
because of a lack of instruments or the instruments are
not “culture-free”. Patients’ explanatory models and perceptions of illness and well-being vary widely across
societies. [77] Defnitions of what is expected from the
treatment, what care providers anticipate for coping with
pain, and what can be labeled as (mal)adaptive coping
will also difer across cultures. Primary care providers
need to be educated in the socio-cultural background
of their patients and should be able to provide the most
effective therapist–patient communication, competent
practice and clinical adherence. While many guidelines
recommend that health care providers screen for psychological and social risk factors, no validated questions have
been proposed. Open-ended questions aimed at screening
for depression, catastrophizing, anxiety and stress, function, coping abilities, and patient expectations are recommended. [75]
In high-income communities, various questionnaires
have been validated. Examples include: the Patient Health
Questionnaire (PHQ) for depression [78, 79]; pain, enjoyment of life and general activity (PEG) for impact of pain
on function [80], Fear Avoidance Beliefs Questionnaire
(FABQ) for avoidance beliefs regarding work and general
activity [81, 82], STarTBack to address fear avoidance,
catastrophizing, and other risk factors for chronicity [83],
and the Core Outcome Measures Index (COMI) including
pain, back and leg, symptom-specifc function, generic
well-being, social disability and work disability, along
with satisfaction with treatment [84, 85] (see Table 1 in
Supplemental File for links to examples of these instruments). While these tools are widely used, they have not
been validated in underserved communities. Before implementation, they require ‘cross-cultural adaptation’ (i.e.,
adapt language and cultural issues to prepare a questionnaire for use in another setting). [86] This process aims at
maximizing “semantic, idiomatic, experiential, and conceptual equivalence between the source and target questionnaires”. [87] Thus, there is then a need for further
evaluation using the new cross-culturally adapted instrument. [88, 89]
Because of the lack of validated instruments for underserved communities, we must consider clinical practice
within the framework of cultural competence. Napier proposes a list of questions to establish cultural and societal
context: “‘What do you call this problem?’; ‘What do you
believe is the cause of this problem?’’ What course do
you expect this problem to take?’’ How serious is it?’;
‘What do you think this problem does inside your body?’;
‘How does this problem afect your body and your mind?’
What do you most fear about this problem?’; ‘What do you
most fear about the treatment?”. [77] These aspects consider psychological and social factors [15, 75], patients’
explanatory models and beliefs, depression, catastrophizing, anxiety and stress, function and interference of spine
problems with daily activities, coping and control over
pain, and expectations about treatment [75] (see Online
Resource Appendix for a clinical vignette). Introducing
open-ended questions regarding psychological and social
factors in the course of the consultation may not prove
particularly demanding or conficting. However, assessing
the patient’s responses may present some difculties for
people with limited health care training or familiarity with
psychosocial factors
Psychological and social flag assessment
Assessment for psychological and social flags (see summary
Table 2 in supplemental fle) should be done at the frst visit
and screened again at 4 and 6 weeks if the patient has not
recovered from back pain. [13, 14] Early identifcation and
modifcation of ‘maladaptive’ thoughts and behaviors helps
prevent the transition from acute to chronic pain and should
be addressed as early as possible. [75] Factors pertaining
to the work environment (e.g., blue and black flags) also
need to be considered. [19, 20] The social and working environment (e.g., unemployment rate, quality of the welfare
system) raise important concerns and need to be included
in patient management. [90, 91] Psychological and social
predictors of chronic disability should be assessed while taking a patient’s history [15, 92]). The European guidelines
for acute and for chronic LBP recommend that psychosocial factors such as work-related factors, psychological distress, patient expectations, and extreme symptoms should
be assessed at the frst primary care visit to identify patients
at risk of developing chronic disability. [93, 94]
Reviews of
clinical guidelines emphasize that clinicians should recognize psychological and social risk factors for chronicity and
manage acute LBP patients with early and gradual activation and avoidance of bed rest. [27, 60] For chronic LBP,
recommended psychosocial interventions include cognitive behavioral therapies. [57] However, clinician-guided
cognitive-behavioral therapies, mindfulness therapy, or
multidisciplinary treatments are not readily available in all
areas. An approach to be considered in these situations is
“psychologically informed practice”. This approach could
be a ‘middle way’ between narrowly focused standard physical therapy practice based on biomedical principles and the
more cognitive behavioral-oriented approaches originally
developed for the treatment of mental illness. [95] The psychologically informed practice approach aims at preventing
pain-related activity limitations. Emotional factors, such as
anxiety, depression, or anger, that are possibly associated
with patients’ beliefs, are addressed as potential obstacles to
recovery as they may infuence behavioral responses. Such a
practice method builds on the professional expertise of care
providers, while integrating specifc and orderly attention to
psychological and social factors.
Health care provider role
Health care providers have an important role in recommending
adequate work restrictions and participation. Considered in a
wider context, primary care involves all providers delivering
the frst-line interventions that most often include physicians,
traditional healers and nurses, physical therapists, and other
health care providers. Health care providers can contribute
to prevent activity and work disability by reassuring patients
that activities can be resumed safely, even if pain is still present. [53] Therefore, clinicians need to understand the work
context in relation to the capacity and beliefs of the patients. [53] It is important that health care providers are trained and
have a strong understanding of psychological and social issues
and their impact on patient acceptance and response to care.
For example, the Australian Musculoskeletal Education Collaboration training programs incorporate these competencies
within their framework. [96, 97]
As noted above, a psychologically informed practice approach aiming at preventing painrelated activity limitations, and building on the professional
expertise of care providers [95], may be of particular interest.
Listening, reassurance, and information from the physician
are important in patient satisfaction and help meet patients’
perceived needs. [98] These needs include the reduction of
emotional uncertainty in a situation of stress and vulnerability. [99, 100] In such situations, the clinician should investigate
further including patient’s perceptions, reaction pain and its
consequences. Symptoms may infuence patients’ perceptions
of what might be wrong and their reaction to pain. Therefore,
symptom awareness and understanding infuence expectations
and satisfaction and contribute to meaningful and acceptable
outcomes. [32]
Recommendations
When a patient presents with acute LBP, health care providers should:
(1) screen for psychosocial flags,
(2) investigate and discuss irrational or maladaptive beliefs and
(3) reassure and educate patients.
In the acute phase, one goal is to
prevent chronicity, thus should include careful evaluation. [75]
Other treatment goals during the acute phase include:
(1) improve function,
(2) modify psychological and social barriers once maladaptive psychological responses to pain have been targeted, and
(3) multidisciplinary rehabilitation including psychological therapy if available. [65]
Patients
with chronic pain may benefit from multidisciplinary
biopsychosocial rehabilitation that aims to improve backrelated physical dysfunction, address psychological issues,
and targets social- and work-related behaviors. However, the
prescription of multidisciplinary biopsychosocial rehabilitation should be informed by the availability of necessary
resources. [76] The resources, however, to provide these
services are not available in most settings. What is required
is appropriate triage and evaluation of available tools and
treatments in each setting.
Strengths and limitations
To the best of our knowledge, this is the frst focused review
on psychological and social issues in low back pain in the
context of low- and middle-income communities. While
these issues have received a great deal of attention in industrialized countries since the emergence of the biopsychosocial model of pain and illness, literature is scarce on these
issues in low- and middle-income communities. Limitations
include that this was not a systematic review of the literature.
All languages and other search engines were not explored,
thus some relevant studies may have been missed. Papers
were not reviewed for bias or quality. The focus of the review
was on low back pain, thus other spine-related issues including other spine regions, functional limitations and spine disorders were not included in this review.
Conclusion
Health care providers have the potential to empower patients
to take control of their health outcomes by making them
aware of biopsychosocial relationships with their spine pain
and disability. Therefore, the patients need to be engaged
in establishing treatment goals and negotiating their treatment. Developing psychosocial assessment instruments
specifcally for groups with low literacy is of clear interest
in the context of medically underserved areas and low- and
middle-income countries where psychological and social
factors may be difcult to detect. As a consequence, these
psychological and social factors may also be poorly taken
care of in these locations. If we are to use the instruments
we know best, these instruments will require proper crosscultural validations, taking into account the diverse contexts considered by the GSCI. Such developments would
contribute to the identifcation of psychological, social or
environmental risk factors in these contexts. We know little about these risk factors and even less on how they may
be organized into signifcant clusters in other cultures. This
development may in turn help devising meaningful interventions allowing to prevent pain-related activity limitations
and disability.
