BackgroundThe mental health impact of the 2014–2016 Ebola epidemic has been described among survivors, family members and healthcare workers, but little is known about its impact on the general population of affected countries. We assessed symptoms of anxiety, depression and post-traumatic stress disorder (PTSD) in the general population in Sierra Leone after over a year of outbreak response.MethodsWe administered a cross-sectional survey in July 2015 to a national sample of 3564 consenting participants selected through multistaged cluster sampling. Symptoms of anxiety and depression were measured by Patient Health Questionnaire-4. PTSD symptoms were measured by six items from the Impact of Events Scale-revised. Relationships among Ebola experience, perceived Ebola threat and mental health symptoms were examined through binary logistic regression.ResultsPrevalence of any anxiety-depression symptom was 48% (95% CI 46.8% to 50.0%), and of any PTSD symptom 76% (95% CI 75.0% to 77.8%). In addition, 6% (95% CI 5.4% to 7.0%) met the clinical cut-off for anxiety-depression, 27% (95% CI 25.8% to 28.8%) met levels of clinical concern for PTSD and 16% (95% CI 14.7% to 17.1%) met levels of probable PTSD diagnosis. Factors associated with higher reporting of any symptoms in bivariate analysis included region of residence, experiences with Ebola and perceived Ebola threat. Knowing someone quarantined for Ebola was independently associated with anxiety-depression (adjusted OR (AOR) 2.3, 95% CI 1.7 to 2.9) and PTSD (AOR 2.095% CI 1.5 to 2.8) symptoms. Perceiving Ebola as a threat was independently associated with anxiety-depression (AOR 1.69 95% CI 1.44 to 1.98) and PTSD (AOR 1.86 95% CI 1.56 to 2.21) symptoms.ConclusionSymptoms of PTSD and anxiety-depression were common after one year of Ebola response; psychosocial support may be needed for people with Ebola-related experiences. Preventing, detecting, and responding to mental health conditions should be an important component of global health security efforts.
Aims In HIV-infected individuals, heavy drinking compromises survival. In HIV primary care, the efficacy of brief motivational interviewing (MI) to reduce drinking is unknown, alcohol-dependent patients may need greater intervention and resources are limited. Using interactive voice response (IVR) technology, HealthCall was designed to enhance MI via daily patient self-monitoring calls to an automated telephone system with personalized feedback. We tested the efficacy of MI-only and MI+HealthCall for drinking reduction among HIV primary care patients. Design Parallel random assignment to control (n = 88), MI-only (n = 82) or MI+HealthCall (n = 88). Counselors provided advice/education (control) or MI (MI-only or MI+HealthCall) at baseline. At 30 and 60 days (end-of-treatment), counselors briefly discussed drinking with patients, using HealthCall graphs with MI+HealthCall patients. Setting Large urban HIV primary care clinic. Participants Patients consuming ≥4 drinks at least once in prior 30 days. Measurements Using time-line follow-back, primary outcome was number of drinks per drinking day, last 30 days. Findings End-of-treatment number of drinks per drinking day (NumDD) means were 4.75, 3.94 and 3.58 in control, MI-only and MI+HealthCall, respectively (overall model χ2, d.f. = 9.11,2, P = 0.01). For contrasts of NumDD, P = 0.01 for MI+HealthCall versus control; P = 0.07 for MI-only versus control; and P = 0.24 for MI+HealthCall versus MI-only. Secondary analysis indicated no intervention effects on NumDD among non-alcohol-dependent patients. However, for contrasts of NumDD among alcohol-dependent patients, P < 0.01 for MI+HealthCall versus control; P = 0.09 for MI-only versus control; and P = 0.03 for MI+HealthCall versus MI-only. By 12-month follow-up, although NumDD remained lower among alcohol-dependent patients in MI+HealthCall than others, effects were no longer significant. Conclusions For alcohol-dependent HIV patients, enhancing MI with HealthCall may offer additional benefit, without extensive additional staff involvement.
This article provides a review of empirical evidence linking emotional processes to immune function in humans. Acute stressors have produced mixed effects on immunity, presumably through differential activation of physiological stress systems. Chronic stress has been associated with suppression of immune function, and there is evidence that the immune system may not adapt over time. Effects of stress accompanying social disruption and psychological depression, when demonstrated, have been consistently adverse. Certain personality styles may enhance or degrade immune response. Relationships between psychosocial factors and immunity have been identified for several diseases, including cancer, acquired immune deficiency syndrome, and autoimmune diseases; psychosocial interventions have been tested with variable results. Theoretical and methodological considerations are summarized and directions for future research suggested.
In this experiment, we tested for opioid and nonopioid mechanisms of pain control through cognitive means and the relation of opioid involvement to perceived coping efficacy. Subjects were taught cognitive methods of pain control, were administered a placebo, or received no intervention. Their pain tolerance was then measured at periodic intervals after they were administered either a saline solution or naloxone, an opiate antagonist that blocks the effects of endogenous opiates. Training in cognitive control strengthened perceived self-efficacy both to withstand and to reduce pain; placebo medication enhanced perceived efficacy to withstand pain but not reductive efficacy; and neither form of perceived self-efficacy changed without any intervention. Regardless of condition, the stronger the perceived self-efficacy to withstand pain, the longer subjects endured mounting pain stimulation. The findings provide evidence that attenuation of the impact of pain stimulation through cognitive control is mediated by both opioid and nonopioid mechanisms. Cognitive copers administered naloxone were less able to tolerate pain stimulation than were their saline counterparts. The stronger the perceived self-efficacy to reduce pain, the greater was the opioid activation. Cognitive copers were also able to achieve some increase in pain tolerance even when opioid mechanisms were blocked by naloxone, which is in keeping with a nonopioid component in cognitive pain control. We found suggestive evidence that placebo medication may also activate some opioid involvement. Because placebos do not impart pain reduction skills, it was perceived self-efficacy to endure pain that predicted degree of opioid activation.
This study suggests that brief single-session, one-on-one or group skill-building interventions may reduce HIV/STD risk behaviors and STD morbidity among inner-city African American women in primary care settings.
Rates of chronic diseases are high among Black South Africans. Few studies have tested cognitive-behavioral health-promotion interventions to reduce chronic diseases in South Africa. We tested the efficacy of such an intervention among adolescents in a cluster-randomized controlled trial. We randomly selected 9 of 17 matched-pairs of schools and randomized one school in each pair to the cognitive-behavioral health-promotion intervention designed to encourage health-related behaviors and the other to a HIV/STD risk-reduction intervention that served as the control. Interventions were based on social cognitive theory, the theory of planned behavior, and qualitative data from the target population. Data collectors, blind to participants’ intervention, administered confidential assessments at baseline and 3, 6, and 12 months post-intervention. Primary outcomes were fruit and vegetable consumption and physical activity. Participants were 1,057 grade 6 learners (mean age = 12.4 years), with 96.7% retained at 12-month follow-up. Generalized estimating equations revealed that averaged over the follow-ups, a greater percentage of health-promotion intervention participants than HIV/STD control participants met 5-a-Day fruit and vegetable and physical activity guidelines. The intervention also increased health-promotion knowledge, attitude, and intention, but did not decrease substance use or substance-use attitude and intention. The findings suggest that theory-based, contextually appropriate interventions may increase health behaviors among young adolescents in sub-Saharan Africa.
This experiment tested a cognitive-behavioral rheumatoid arthritis treatment designed to confer skills in managing stress, pain, and other symptoms of the disease. We hypothesized that a mediator of the magnitude of treatment effects might be enhancement of perceived self-efficacy to manage the disease. It was predicted that the treatment would reduce arthritis symptoms and possibly would improve both immunologic competence and psychological functioning. The treatment provided instruction in self-relaxation, cognitive pain management, and goal setting. A control group received a widely available arthritis helpbook containing useful information about arthritis self-management. We obtained suggestive evidence of an enhancement of perceived self-efficacy, reduced pain and joint inflammation, and improved psychosocial functioning in the treated group. No change was demonstrated in numbers or function of T-cell subsets. The magnitude of the improvements was correlated with degree of self-efficacy enhancement.
