The impact of co-occurring mood and anxiety disorders among substance-abusing youth

BACKGROUND: Co-occurring mood and anxiety disorders are highly prevalent amongst substance-using young adolescents, and have been associated with a range of adverse outcomes. Few studies however have examined the impact of affective disorders in samples of older adolescents and young adults attending youth drug treatment services. METHODS: One hundred young people (mean age 19.4 years) were recruited from two youth drug treatment services in Melbourne, Australia. A structured interview and questionnaires assessing drug use, psychopathology, risk-taking behaviours and quality of life were administered at a mutually convenient location. RESULTS: Fifty percent of the sample met criteria for at least one current mental health disorder. Excluding individuals with a current psychotic illness (n=3), 49% met criteria for a current mood or anxiety disorder, with 68% reporting a lifetime history. There were high rates of current Major Depressive Disorder (MDD; 27%) and Post-traumatic Stress Disorder (PTSD; 26%) within the sample. Participants with these disorders were more likely to have a higher number of comorbid disorders, report more substance-related problems and a poorer quality of life. LIMITATIONS: Cross-sectional design, lack of biological assays. CONCLUSIONS: In older adolescence and emerging adulthood, young drug users with comorbid affective disorders have greater mental health and substance use morbidity than those with substance use problems alone. These findings have important clinical implications for the management and rehabilitation of young people with substance use disorders.     

Anxiety and depressive symptoms and anxiety sensitivity in youngsters with noncardiac chest pain and benign heart murmurs

OBJECTIVE: Chest pain in children and adolescents is rarely associated with cardiac disease. We sought to examine psychological symptoms in youngsters with medically unexplained chest pain. We hypothesized that children and adolescents with medically unexplained chest pain would have high rates of anxiety and depressive symptoms. METHODS: We assessed 65 youngsters with noncardiac chest pain (NCCP) and 45 comparison youngsters with benign heart murmurs using self-report measures of anxiety and depressive symptoms and anxiety sensitivity. RESULTS: Compared with the asymptomatic benign-murmur group, youngsters with NCCP had higher levels of some anxiety symptoms and anxiety sensitivity. Differences on depressive symptoms were not significant. CONCLUSIONS: Though preliminary, results suggest that youngsters with chest pain may experience increased levels of some psychological symptoms. Future studies of noncardiac chest pain in youngsters should include larger samples and comprehensive diagnostic assessments as well as long-term follow-up evaluations.     

Validity of the hospital anxiety and depression scale for use with patients with noncardiac chest pain

Consecutive patients seen in the first-heart-aid service of a university hospital and given a diagnosis of noncardiac chest pain completed the self-report Hospital Anxiety and Depression Scale. Patients with a score >or=8 on either the anxiety or depression subscale (N=266, mean age=55.81 years, SD=13.03, 143 male patients) were compared with patients scoring <8 (N=78, mean age=60.55 years, SD=10. 84, 50 male patients) by means of the Mini International Neuropsychiatric Interview. Panic disorder and/or depression identified by the diagnostic interview were highly prevalent in the group with a score >or=8 (73.3% versus 3.9% in the comparison group). The Hospital Anxiety and Depression Scale is an adequate screening instrument for the detection of affective disorders in patients with noncardiac chest pain.     

The prevalence of anxiety disorders among patients with mitral valve prolapse syndrome and chest pain

Nineteen patients from a cardiology practice with complaints of chest pain and with mitral valve prolapse syndrome were compared with 26 patients with chest pain but no discernible cardiac disorder. Instruments included a truncated form of the Diagnostic Interview Schedule, the symptom checklist 90 revised (SCL-90-R), the McGill Pain Questionnaire, and life events, physical activity, and family history questionnaires. Neither panic disorder nor self-rated anxiety were more common in the mitral valve prolapse group. This study failed to confirm the reported high association between mitral valve prolapse syndrome and panic disorder.     

Morbidity of DSM-IV Axis I disorders in patients with noncardiac chest pain: Psychiatric morbidity linked with increased pain and health care utilization

The present study examined current and lifetime psychiatric morbidity, chest pain, and health care utilization in 229 patients with noncardiac chest pain (NCCP), angina-like pain in the absence of cardiac etiology. Diagnostic interview findings based on the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) revealed a psychiatrically heterogeneous sample of whom 44% had a current Axis I psychiatric disorder. A total of 41% were diagnosed with a current anxiety disorder, and 13% were diagnosed with a mood disorder. Overall, 75% of patients had an Axis I clinical or subclinical disorder. Lifetime diagnoses of anxiety (55%) and mood disorders (44%) were also prevalent, including major depressive disorder (41%), social phobia (25%), and panic disorder (22%). Patients with an Axis I disorder reported more frequent and more painful chest pain compared with those without an Axis I disorder. Presence of an Axis I disorder was associated with increased life interference and health care utilization. Findings reveal that varied DSM-IV Axis I psychiatric disorders are prevalent among patients with NCCP, and this psychiatric morbidity is associated with a less favorable NCCP presentation. Implications for early identification of psychiatric disorders are discussed.     

Heart-focused anxiety and chest pain in postangiography medical patients

The present cross-sectional study sought to examine the extent to which heart-focused anxiety is associated with the co-occurrence of coronary artery disease (CAD) and a history of regular smoking in a sample of 148 postangiography patients from a cardiology unit. Individuals with CAD who regularly smoked demonstrated significantly greater heart-focused attention, but no greater degree of avoidance and fear of heart-focused sensations, than did nonsmoking persons with CAD and smokers without CAD. We also found evidence that heart-focused attention and fear incrementally predicted (above and beyond demographic variables and body mass index) intensity of average chest pain. Overall, this study provides some of the first empirical evidence that the co-occurrence of regular smoking and CAD is associated with specific dimensions of health anxiety. We discuss these findings in relation to models of panic pathology and anxious responding to bodily sensations.     

Effects of perceived stress on pediatric chronic pain

The dearth of theoretically driven research on the predictors of pediatric chronic pain may unwittingly contribute to needless suffering in children and adolescents by underinvestigating a potentially treatable condition. The objective of the present study was to investigate the hypothesized predictive effects of perceived stress on pediatric chronic pain intensity in 148 children and adolescents. Consistent with thea priori Biobehavioral Model of Pediatric Pain, higher perceived stress was predictive of greater pediatric pain intensity. The results are discussed with regard to the implications for cognitive-behavioral pediatric pain treatment.     

Oxidative stress in anxiety and comorbid disorders

Anxiety disorders, depression, and alcohol use disorder are common neuropsychiatric diseases that often occur together. Oxidative stress has been suggested to contribute to their etiology. Oxidative stress is a consequence of either increased generation of reactive oxygen species or impaired enzymatic or non-enzymatic defense against it. When excessive it leads to damage of all major classes of macromolecules, and therefore affects several fundamentally important cellular functions. Consequences that are especially detrimental to the proper functioning of the brain include mitochondrial dysfunction, altered neuronal signaling, and inhibition of neurogenesis. Each of these can further contribute to increased oxidative stress, leading to additional burden to the brain. In this review, we will provide an overview of recent work on oxidative stress markers in human patients with anxiety, depressive, or alcohol use disorders, and in relevant animal models. In addition, putative oxidative stress-related mechanisms important for neuropsychiatric diseases are discussed. Despite the considerable interest this field has obtained, the detailed mechanisms that link oxidative stress to the pathogenesis of neuropsychiatric diseases remain largely unknown. Since this pathway may be amenable to pharmacological intervention, further studies are warranted.     

The potential impact of mindfulness on exposure and extinction learning in anxiety disorders

Mindfulness based approaches have shown promise in the treatment of various anxiety disorders. However, further research is needed to more precisely elucidate mechanisms of action through which mindfulness practice may enhance treatment for anxiety. Given centrality of exposure-based procedures in the treatment of anxiety, it is important to consider ways in which mindfulness may affect exposure and extinction processes. In fact, numerous findings in the basic science of extinction point to the possible ways in which mindfulness may facilitate extinction learning. The present paper aims to critically review the literature surrounding mindfulness and extinction learning in order to more fully explore the ways in which mindfulness-based treatments may positively impact exposure and extinction processes in the treatment of anxiety disorders. This will provide a unique synthesis of newer, acceptance-based behavior therapies with established principles of effective behavioral treatments.     

The impact of task controllability on perceived control and cardiovascular processes

This article examines the impact of task control on perceived control and cardiovascular processes. Fifty‐eight undergraduates performed a computer task where the functionality of the computer mouse was used to manipulate task control. Results are consistent with the proposition that actual control triggers an initial physiological response which can be modified temporally later by perceived control and that male participants react psychologically faster to changes in task control than female participants.     

The impact of preoperative information on state anxiety, postoperative pain and satisfaction with pain management

The primary objective of this study was to test whether specific information given prior to surgery can help patients obtain better pain relief after total knee arthroplasty (TKA). Secondary objectives were to study the impact of preoperative information on state and trait anxiety, satisfaction with pain management and satisfaction with nursing care. The study was an intervention study with two groups of equal size (n=30). The intervention group was given specific information while the control group received routine information. Pain assessments were made preoperatively and every 3h for the first three postoperative days, using the visual analogue scale (VAS). The results of this study suggest that information does influence the experience of pain after surgery and related psychological factors. The postoperative pain declined more rapidly for patients in the treatment group, the degree of preoperative state anxiety was lower and they were more satisfied with the postoperative pain management.     

Coping in chest pain patients with and without psychiatric disorders

We first examined relations between psychiatric disorder and coronary heart disease (CHD) in 77 patients presenting with chest pain. The coping profiles of chest pain patients with and without psychiatric disorder and CHD were then compared. Psychiatric patients with no medical illness (n = 129) were also studied. On the basis of previous research we hypothesized specific coping differences across the groups. As expected, chest pain patients without psychiatric disorder scored significantly higher on a problem-focused coping scale than chest pain patients with psychiatric disorder, who in scored higher on this scale than psychiatric patients with no medical illness. The opposite pattern occurred for a measure of wishful thinking. Scores of chest pain patients with psychiatric disorder were higher on a measure of avoidance and lower on a measure of seeking of social supports than those without psychiatric disorder. Scores on a self-blame measure were not different across the groups. The results are discussed in the context of illness behavior and somatization.     

Use of herbal medicine in primary care patients with mood and anxiety disorders

Studies have documented the increasing use of complementary and alternative medicine over the last decade, especially in distressed individuals with symptoms of anxiety, depression, and pain. Herbal medicine is a specific form of complementary and alternative medicine often used by individuals seeing traditional medical practitioners and, hence, has the potential to interact with other medically prescribed treatments. The study examined the use of herbal medicine in a group of primary care patients with symptoms of anxiety and depression. The rate of use of herbal medicines was 11%, and use was selectively associated with a diagnosis of major depression, higher education, and a lower burden of medical illness. Use was not associated with receipt of pharmacotherapy or psychotherapy for anxiety or depression.
