Pain interference and incident mood,anxiety, and substance-use disorders: Findings from a representative sample of men and women in the general population

To examine gender differences in the longitudinal relationship between past-month pain interference and incident mood, anxiety, and substance-use disorders, chi-square tests and binomial logistic regression analyses were performed on data obtained from the National Epidemiologic Survey on Alcohol and Related Conditions from 34,465 adult respondents (47.9% men; 52.1% women) who completed waves 1 (2000–2001) and 2 (2004–2005) data collection. Models were adjusted for potentially confounding factors (i.e., age, race, marital status, educational level, employment, household income, number of stressful life events, number of general medical conditions, and wave-1 psychopathology). Respondents were categorized at wave 1 according to their past-month level of pain interference (i.e., no or low pain interference, moderate pain interference, severe pain interference). Moderate and severe pain interference (as compared to no or low pain interference) in male and female respondents was associated with the incidence of several psychiatric disorders. A stronger relationship was observed in male respondents as compared to female ones between past-month moderate pain interference and a new onset of any mood disorder (OR = 1.57, p = 0.03) and major depressive disorder (OR = 1.60, p = 0.03), and between past-month severe pain interference and a new onset of alcohol abuse or dependence (OR = 1.69, p = 0.045) and nicotine dependence (OR = 1.48, p = 0.04). These findings suggest that providers should consider screening patients with past-month moderate or severe pain interference for mood, anxiety, and substance-use problems and monitor the possible development of subsequent comorbid psychiatric disorders.     

Clinical correlates of social adjustment in patients with obsessive-compulsive disorder

BackgroundPatients with obsessive-compulsive disorder (OCD) frequently show poor social adjustment, which has been associated with OCD severity. Little is known about the effects that age at symptom onset, specific OCD symptoms, and psychiatric comorbidities have on social adjustment. The objective of this study was to investigate the clinical correlates of social functioning in OCD patients.MethodsCross-sectional study involving 815 adults with a primary DSM-IV diagnosis of OCD participating in the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders. Patients were assessed with the Social Adjustment Scale, the Medical Outcomes Study 36-item Short-Form Health Survey, the Yale-Brown Obsessive-Compulsive Scale, the Dimensional Yale-Brown Obsessive-Compulsive Scale, and the Structured Clinical Interview for DSM-IV Axis I Disorders. Clinical correlates of social adjustment were assessed with generalized linear models with gamma distribution.ResultsPoor overall social functioning was associated with greater OCD severity (p = 0.02); hoarding symptoms (p = 0.004); sexual/religious obsessions (p = 0.005); current major depressive disorder (p = 0.004); current post-traumatic stress disorder (p = 0.002); and current eating disorders (p = 0.02). Poor social adjustment was also associated with impaired quality of life.ConclusionsPatients with OCD have poor social functioning in domains related to personal relationships and professional performance. Hoarding symptoms and sexual/religious obsessions seem to have the strongest negative effects on social functioning. Early age at OCD symptom onset seems to be associated with professional and academic underachievement and impairment within the family unit, whereas current psychiatric comorbidity worsen overall social functioning. In comparison with quality of life, social adjustment measures seem to provide a more comprehensive overview of the OCD-related burden.     

Personality disorders associated with full and partial posttraumatic stress disorder in the U.S. population: results from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions

Background

While it is well known that personality disorders are associated with trauma exposure and PTSD, limited nationally representative data are available on DSM-IV personality disorders that co-occur with posttraumatic stress disorder (PTSD) and partial PTSD.

Methods

Face-to-face interviews were conducted with 34,653 adults participating in the Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions. Logistic regression analyses controlling for sociodemographics and additional psychiatric comorbidity evaluated associations of PTSD and partial PTSD with personality disorders.

Results

Prevalence rates of lifetime PTSD and partial PTSD were 6.4% and 6.6%, respectively. After adjustment for sociodemographic characteristics and additional psychiatric comorbidity, respondents with full PTSD were more likely than trauma controls to meet criteria for schizotypal, narcissistic, and borderline personality disorders (ORs = 2.1-2.5); and respondents with partial PTSD were more likely than trauma controls to meet diagnostic criteria for borderline (OR = 2.0), schizotypal (OR = 1.8), and narcissistic (OR = 1.6) PDs. Women with PTSD were more likely than controls to have obsessive-compulsive PD. Women with partial PTSD were more likely than controls to have antisocial PD; and men with partial PTSD were less likely than women with partial PTSD to have avoidant PD.

Conclusions

PTSD and partial PTSD are associated with borderline, schizotypal, and narcissistic personality disorders. Modestly higher rates of obsessive-compulsive PD were observed among women with full PTSD, and of antisocial PD among women with partial PTSD.     

Gambling problem severity and psychiatric disorders among Hispanic and white adults: findings from a nationally representative sample

Objective

To examine differences in the associations of gambling problem severity and psychiatric disorders among a nationally representative sample of Hispanic and white adults.

Method

Chi-square tests and multinomial logistic regression analyses were performed on data obtained from the National Epidemiologic Survey on Alcohol and Related Conditions from 31,830 adult respondents (13% Hispanic; 87% white), who were categorized according to three levels of gambling problem severity (i.e., no gambling or low-frequency gambling [NG], low-risk or at-risk gambling [LRG], problem or pathological gambling [PPG]).

Results

Hispanic respondents in comparison to white respondents were more likely to exhibit PPG. Problem gambling severity was associated with past-year Axis I and lifetime Axis II psychiatric disorders in both Hispanic and white respondents, with the largest odds typically observed in association with the most severe gambling pathology. A stronger relationship between subsyndromal gambling and a broad range of Axis I disorders (mood, anxiety and substance use disorders) and Axis II disorders (particularly cluster B) was observed in Hispanic respondents as compared to white ones.

Conclusions

Levels of problem gambling severity are associated with the prevalence of Axis I and Axis II psychiatric disorders in both Hispanics and whites. Differences in the patterns of co-occurring disorders between subsyndromal levels of gambling in Hispanic and white respondents indicate the importance of considering ethnicity/race-related factors related to subthreshold levels of gambling in developing improved mental health prevention and treatment strategies.     

Psychiatric disorders in patients with essential tremor

BackgroundPrevious studies have reported that a consistent proportion of patients with Essential Tremor may have psychiatric disorders but it is unclear whether these disorders are increased in frequency as compared to healthy subjects.MethodsIn a case-control study, we adopted the structured interviews for DSM-IV, SCID-I and SCID-II, to investigate psychiatric and personality disorders in 37 ET patients and 34 healthy subjects. As cognitive changes in ET may be a confounding factor we enrolled patients and healthy control subjects without cognitive dysfunction.ResultsSCID-I showed that Axis-I psychiatric disorders, mainly depressive disorders, were more frequent in ET patients (20 of 37; 54%) than in healthy subjects (8 of 34; 22%) (p < 0.01). Depressive disorders were more frequent in patients with a family history of ET (p < 0.05) in comparison to patients without a family history. SCID-II disclosed that the frequency of personality disorders was similar in patients with ET and healthy subjects.ConclusionPsychiatric disorders may be associated to the neurological manifestations of ET.     

Psychotic boys performing well in school are at increased risk of suicidal ideation

Aim:  This study investigated how the level of school performance is associated with suicidal behavior and psychiatric disorders among adolescent psychiatric inpatients aged 12–17 years.
Methods:  Data were collected from 508 adolescents (300 girls, 208 boys; age 12–17 years) admitted to inpatient psychiatric hospitalization between April 2001 and March 2006. Information on the adolescents' school performance, suicidal ideation, suicide attempts and self-mutilation as well as psychiatric DSM-IV diagnoses was obtained using the Schedule for Affective Disorder and Schizophrenia for School-Age Children.
Results:  An elevated risk of suicidal ideation (OR = 3.6, 95% CI 1.3–10.2, P  = 0.017) and of psychotic disorders (OR = 3.2, 95% CI 1.0–10.0, P  = 0.048) was observed among male adolescents performing well in school. In addition, adolescents with poor school performance had an increased likelihood of substance-related disorder both in boys (OR = 2.6, 95% CI 1.1–6.1, P  = 0.027) and girls (OR = 2.5, 95% CI 1.2–5.1, P  = 0.011).
Conclusions:  Our findings indicate that psychotic inpatient male adolescents performing well in school are at an elevated risk of suicidal ideation. Although good school performance is often considered a marker of high intelligence and good general ability, symptoms of major psychiatric disorders and suicidality need to be taken very seriously among adolescents performing well in school.     

Axis I and Axis II psychiatric disorders in patients with fibromyalgia

ObjectiveTo determine the current prevalence of Axis I and Axis II psychiatric disorders in patients with fibromyalgia.MethodThe study sample includes 103 patients with fibromyalgia and 83 control subjects. Axis I and Axis II disorders were determined by structured clinical interviews.ResultsThe rate of any Axis I psychiatric disorder (47.6% vs. 15.7%), major depression (14.6% vs. 4.8%), specific phobia (13.6% vs. 4.8%), any Axis II disorder (31.1% vs. 13.3%), obsessive–compulsive (23.3% vs. 3.6%) and avoidant (10.7% vs. 2.4%) personality disorders were significantly more common in the patient group compared to the control group.ConclusionOur results suggest that a considerable proportion of patients with fibromyalgia also present with Axis I and Axis II psychopathologies.     

The influence of personality disorders on the use of mental health services in adolescents with psychiatric disorders

ObjectiveThe aims of this study were to explore the influence of personality disorders (PDs) in Spanish adolescents with Axis I psychiatric disorders on their use of mental health services and to analyze the risk of having a comorbid PD in relation to psychiatric service use.MethodsThe Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) and International Classification of Diseases, Tenth Revision (ICD-10) modules of the semistructured interview International Personality Disorders Examination were administered to a sample of 112 adolescent psychiatric patients (mean age = 15.8 years; SD, 0.8; range, 15-17; 79% women) at the point of initiating treatment. On the basis of the interview, subjects were divided into two groups: a PD group (PDG) and a non-PD group (NPDG). After 3 years of treatment, clinical records were retrospectively analyzed.ResultsThe PDG showed a significantly higher number of psychiatric admissions (P < .001), days per psychiatric admission (P < .001), and psychiatric emergencies (P < .010) than the NPDG, although the number of outpatient consultations was not significantly higher. Logistic regression analysis showed that the probability of belonging to the PDG rather than the NPDG increased with each psychiatric admission (odds ratio [OR] = 1.67 for DSM-IV criteria and OR = 1.59 for ICD-10 criteria), after controlling by sex, age, and comorbidity (Axis I disorders).ConclusionsPatients with comorbid PD used more inpatient and emergency psychiatric services than did patients without a PD. Large number of psychiatric hospitalizations suggests the likelihood of a PD being present.     

Co-occurrence of Axis I and Axis II disorders in female and male patients with panic disorder with agoraphobia

Objective

The aim of this study is to compare female and male patients with panic disorder with agoraphobia (PDA) for the co-occurring Axis I and Axis II (personality) disorders, to better understand sex differences in PDA.

Methods

The Structured Clinical Interview for Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition (DSM-IV) Axis I Disorders, Clinician Version and the Structured Clinical Interview for DSM-IV Axis II Personality Disorders were administered to 157 consecutive outpatients (112 females and 45 males) with principal diagnosis of PDA, who sought treatment at the 2 anxiety disorders clinics. Women and men with PDA were then compared with regard to the type and frequency of the co-occurring Axis I and Axis II disorders.

Results

Women with PDA had a statistically greater tendency to receive co-occurring Axis I diagnoses and a greater number of Axis I diagnoses than men. Such a difference was not found for personality disorders. However, no sex difference was found for the mean number of co-occurring Axis I and Axis II diagnoses per patient. There were significantly more women with at least one co-occurring anxiety disorder. Women had a significantly higher frequency of specific phobia, whereas men were diagnosed with hypochondriasis and past alcohol abuse or dependence significantly more often. With regard to Axis II disorders, the only significant sex difference pertained to the higher frequency of dependent personality disorder among women.

Conclusions

The results of this study suggest that there are more similarities than differences between sexes in the co-occurring Axis I and Axis II disorders. Still, the relatively specific relationships between PDA and excessive alcohol use in men and between PDA and dependent personality traits and personality disorder in women seem important and have implications for clinical practice and treatment.     

Long-term outcomes and predictors of chronic insomnia: a prospective study in Hong Kong Chinese adults

ObjectivesWe aimed to determine the longitudinal course and outcome of chronic insomnia in a five-year prospective study in Hong Kong Chinese adults.MethodsTwo thousand three hundred and sixteen middle-aged adults (53.3% females, 46.3 ± 5.1 years old at follow-up) were recruited at baseline and follow-up. Participants were divided into three groups: non-insomnia, insomnia symptoms, and insomnia syndrome (insomnia symptoms plus daytime symptoms). Upper airway inflammatory diseases, mental problems, and medical problems were additionally assessed at follow up.ResultsThe incidence of insomnia (symptoms and syndrome) was 5.9%. The persistence rate of insomnia syndrome was 42.7% for insomnia syndrome and 28.2% for insomnia symptoms. New incidence of insomnia was associated with younger age, unemployment, and daytime symptoms, while persistence of insomnia was associated with female sex, lower education level, and daytime symptoms at the baseline (p < 0.05). Baseline insomnia syndrome was significantly associated with upper airway inflammatory diseases (including asthma and laryngopharyngitis; adjusted OR = 1.97–17.9), mental problems, and medical conditions (including arthritis, psychiatric disorders, chronic pain, and gastroesophageal reflux disease; AOR = 2.29–3.77), whereas baseline insomnia symptoms were associated with poor mental health (AOR = 2.43), psychiatric disorders (AOR = 2.39), and chronic pain (AOR = 2.95).ConclusionsChronic insomnia is a common problem with considerable persistence and incidence rates among middle-aged Chinese adults. Insomnia syndrome has a higher persistence rate with more mental and medical comorbidities when compared with insomnia symptoms without daytime consequences.     

Genetic variants in nuclear-encoded mitochondrial proteins are associated with oxidative stress in obsessive compulsive disorders

Obsessive compulsive disorder is a common psychiatric disorder defined by the presence of obsessive thoughts and repetitive compulsive actions. The mutations or polymorphic variants in mitochondrial DNA-encoded genes or nuclear genes result in oxidative stress, which has recently been associated with various psychiatric disorders. In order to understand the association of mitochondrial disorders with oxidative stress in obsessive compulsive disorder, we examined genetic variants of manganese superoxide dismutase and uncouple-2 antioxidant genes and malondialdehyde and glutathione, markers of oxidative stress. The study sample comprised 104 patients with OCD and 110 healthy controls. For manganese superoxide dismutase, the frequencies of CT (Ala/Val) genotype (p < 0.01) in patients were significantly lower than those of controls. In contrast, CC (Ala/Ala) genotype was significantly more frequent in patients than controls (p < 0.05). For uncouple-2 I/D, the frequencies of ID genotype (p < 0.01) and I allele (p < 0.05) were lower in patients as compared with controls. In contrast, DD genotype was more prevalent in patients than controls (p < 0.01). While whole blood glutathione was significantly diminished (p < 0.0001), serum malondialdehyde was significantly elevated in patients compared with controls (p < 0.0001). Malondialdehyde levels were significantly elevated in subjects with DD genotype of UCP-2 I/D (p < 0.05) and CC genotype of manganese superoxide dismutase (p < 0.05) as compared with II or ID and TT or CT genotype, respectively. Malondialdehyde levels in patients carrying CC (p < 0.05) or CT (p < 0.05) genotype were significantly higher than those of carrying TT genotype. In conclusion, CC genotype of manganese superoxide dismutase or DD genotype of UCP-2 might result in mitochondrial disorders by increasing oxidative stress in obsessive compulsive disorders.     

Gender differences in the associations between past-year gambling problems and psychiatric disorders

Background Psychiatric disorders frequently co-occur with pathological gambling. The extent to which co-occurence extends to subsyndromal levels of gambling or differs between women and men is incompletely understood. Aim To examine whether the association between psychiatric disorders and past-year gambling problems is stronger in women than men. Methods Data from the national epidemiological survey of alcoholism and related disorders (NESARC) (n = 43,093) were analyzed. Results Increasing severity of past-year gambling problems was associated with increasing odds of most past-year Axis I and lifetime Axis II disorders, regardless of gender. Associations between gambling problems and major depression, dysthymia, panic disorder, and nicotine dependence were statistically stronger in women than in men. Conclusions A severity-related association exists between past-year gambling problems and psychiatric disorders. The stronger associations in women suggest that gambling research, prevention and treatment efforts consider gender differences.     

Effects of gender and dementia severity on Alzheimer's disease caregivers' sleep and biomarkers of coagulation and inflammation

Background: Being a caregiver for a spouse with Alzheimer’s disease is associated with increased risk for cardiovascular illness, particularly for males. This study examined the effects of caregiver gender and severity of the spouse’s dementia on sleep, coagulation, and inflammation in the caregiver.Methods: Eighty-one male and female spousal caregivers and 41 non-caregivers participated (mean age of all participants 70.2 years). Full-night polysomnography (PSG) was recorded in each participants home. Severity of the Alzheimer’s disease patient’s dementia was determined by the Clinical Dementia Rating (CDR) scale. The Role Overload scale was completed as an assessment of caregiving stress. Blood was drawn to assess circulating levels of D-dimer and Interleukin-6 (IL-6).Results: Male caregivers who were caring for a spouse with moderate to severe dementia spent significantly more time awake after sleep onset than female caregivers caring for spouses with moderate to severe dementia (p = .011), who spent a similar amount of time awake after sleep onset to caregivers of low dementia spouses and to non-caregivers. Similarly, male caregivers caring for spouses with worse dementia had significantly higher circulating levels of D-dimer (p = .034) than females caring for spouses with worse dementia. In multiple regression analysis (adjusted R² = .270, p < .001), elevated D-dimer levels were predicted by a combination of the CDR rating of the patient (p = .047) as well as greater time awake after sleep onset (p = .046).Discussion: The findings suggest that males caring for spouses with more severe dementia experience more disturbed sleep and have greater coagulation, the latter being associated with the disturbed sleep. These findings may provide insight into why male caregivers of spouses with Alzheimer’s disease are at increased risk for illness, particularly cardiovascular disease.     

Physician speciality and pain reduction in patients with depressive symptoms under treatment with venlafaxine

ObjectivesExcessive pain perception may lead to unnecessary diagnostic testing or invasive procedures resulting in iatrogenic complications and prolonged disability. Naturalistic studies on patients with chronic pain and depressive symptoms investigating the impact of medical speciality on treatment outcome in a primary care setting are lacking.MethodsIn this observational study, we examined whether the magnitude of pain reduction in 444 patients with depressive symptomatology under venlafaxine would relate differently to the medical speciality of the 122 treating physicians, namely psychiatrists (n = 110 patients), general practitioners (n = 236 patients), and internists (n = 98 patients).ResultsIndependent of age, gender, patient's region of origin, comorbidity, severity and duration of pain, and depressive symptoms at study entry, patients seemed to benefit significantly less in terms of pain reduction (p < 0.001) and of reduction in severity of depressive symptomatology by psychiatrists as compared to general practitioners (p < 0.019) and internists (p < 0.002).ConclusionsThe findings suggest that patients referred to psychiatrists are more difficult to treat than those referred to general practitioners and internists, and might not have been adequately prepared for psychiatric interventions. A supporting cooperation and networking between psychiatrists and primary care physicians may contribute to an integrated treatment concept and therefore, may lead to a better outcome in this challenging patient group.     

Restless Legs Syndrome and the five-factor model of personality: results from a community sample

ObjectiveTo examine personality characteristics as potential mediators of the association between Restless Legs Syndrome (RLS) and psychiatric disorders.MethodRevised NEO Personality Inventory traits are compared in respondents with (n = 42) versus without (n = 982) a diagnosis of RLS in a general population sample.ResultsRLS was associated with higher neuroticism after adjusting for potential confounders, including current psychopathology. Further analysis showed that the association between RLS and neuroticism contributes to, but does not fully explain, the relationship between RLS and either panic disorder or major depression.ConclusionsNeuroticism may mediate part of the relationship between RLS and depression or panic, but the mechanisms of these associations need further exploration.     

Apathy and impulse control disorders in Parkinson's disease: a direct comparison

BackgroundApathy and impulse control disorders (ICDs) in Parkinson’s disease (PD) are clinically important complications and may exist on a common behavioral spectrum of disorders of reward and motivation.ObjectiveTo directly compare PD participants with apathy those with ICDs on range of demographic, neurologic and psychiatric measures.MethodsNinety-nine non-demented PD participants (ICD, n = 35; apathy, n = 26; and controls, n = 38) were assessed in the study. Univariate statistics were used to compare the behavioral groups. A linear regression model was created with either apathy or impulsivity as the dependent variable.ResultsThe two behavioral groups differed significantly from the PD control group on similar factors but in opposite directions. The apathy group was older at the time of both assessment and disease onset, had higher levels of depression and lower dopamine agonist use, compared to the other two groups. The ICD group was younger than the apathy group at disease onset and had higher levels of anxiety, a higher overall dopamine load and greater motor disease complexity. Overlap in behavioral pathology across the two groups was also noted.ConclusionApathy and ICDs may be on a common behavioral spectrum in PD. Both are associated with significant psychiatric morbidity supporting shared underlying pathology.     

Longterm persistence and nonrecurrence of depression treatment in Germany: a four‐year retrospective follow‐up using linked claims data

Objectives

To measure persistence and nonrecurrence of depression treatment and investigate potential risk factors.

Methods

We retrospectively observed a closed cohort of insurees with new‐onset depression treatment in 2007 and without most psychiatric comorbidity for 16 quarters (plus one to ascertain discontinuation). We linked inpatient/outpatient/drug‐data per person and quarter. Person‐quarters containing specified depression services were classified as depression‐treatment‐person‐quarters (DTPQ). We defined longterm‐DTPQ‐persistence as 16 + 1 continuous DTPQ and longterm‐DTPQ‐nonrecurrence as 12 continuous quarters without DTPQ and used multivariate logistic regression to explore associations with these outcomes.

Results

Within first 16 quarters, 28,348 patients' first period (total time) persisted for a mean/median 5.4/3 (8.7/8) quarters. Fourteen percent had longterm‐DTPQ‐persistence, associated (p < .05) with baseline hospital (odds ratio, OR = 1.80), psychotherapy/specialist‐interview and antidepressants (OR = 1.81), age (years, OR = 1.03), unemployment (OR = 1.21), retirement (OR = 1.31), and insured as a dependent (OR = 1.32). Thirty‐four percent had longterm‐DTPQ‐nonrecurrence, associated with psychotherapy/specialist‐interview (OR = 1.40), antidepressants (OR = 0.54), female sex (OR = 0.84), age (years, OR = 0.99), retirement (OR = 1.18), and insured as a dependent (OR = 0.88). Women differed for episodic and not chronic treatment.

Conclusion

Treatment measures compared to survey's symptoms measures. We suggest further research on “treatment‐free‐time.” Antidepressants(?) and psychotherapy/specialist‐interview(+) were significantly associated with longterm‐DTPQ‐nonrecurrence. This was presumably moderated by possible short‐time/low‐dosage antidepressants use(?) and selective therapy assignment(+). Sample selectivity limited data misclassification.

     

Salivary testosterone: associations with depression, anxiety disorders, and antidepressant use in a large cohort study

ObjectiveLow circulating levels of testosterone have been associated with major depression, but there is more limited evidence for differences in patients with anxiety disorders. The use of selective serotonin reuptake inhibitors (SSRIs) and other antidepressants is associated with sexual side effects, warranting testing for interactions with testosterone.MethodsData are from 722 male and 1380 female participants of The Netherlands Study of Depression and Anxiety (NESDA), who were recruited from the community, general practice care, and specialized mental health care. Depressive and anxiety diagnoses were assessed using the DSM-IV Composite International Diagnostic Interview. To smooth the episodic secretion, the four morning saliva samples per participant and the two evening samples were pooled before testosterone analysis.ResultsMorning median testosterone levels were 25.2 pg/ml in men and 16.2 pg/ml in women, with lower evening levels of 18.2 and 14.1 pg/ml, respectively. Significant determinants of testosterone levels were sex, age, time of the day, use of contraceptives, and smoking status. Female patients with a current (1-month) depressive disorder (effect size 0.29; P = 0.002), generalized anxiety disorder (0.25; P = 0.01), social phobia (0.30; P < 0.001), and agoraphobia without panic disorder (0.30; P = 0.02) had lower salivary testosterone levels than female controls. Higher testosterone levels were found in male and female participants using SSRIs than in non-users (effect size 0.26; P < 0.001).ConclusionSalivary testosterone levels are lower in female patients with a depressive disorder, generalized anxiety disorder, social phobia, and agoraphobia as compared to female controls. SSRIs may increase salivary testosterone in men and women.     

Comorbid Psychiatric Disorders and Predictors of Pain Management Program Success in Patients With Chronic Pain

BACKGROUND: This prospective investigation assessed success rates of a pain management program for patients with and without DSM-III-R Axis I and II psychiatric disorders. METHOD: Subjects included 40 consecutive patients with chronic pain who were referred to a physical therapy-oriented, "standard" pain management program. Serial ratings of pain levels were measured via a visual analogue scale (VAS) at baseline, weekly throughout a 12-week program, and during a follow-up interval 1 month after completion of the program. Weekly reports of hours of gainful employment were recorded. VAS scores and number of hours worked per week were combined into a measure of pain improvement. This dependent variable was used to compare groups of patients across psychiatric disorders diagnosed via the Diagnostic Interview Schedule (DIS). Percentages of patients in each diagnostic group who met minimal criteria for improvement were computed and compared. A chi-square analysis was conducted on success rates between patients with and without any Axis I disorder, any Axis II disorder, and any substance abuse/dependence disorder. RESULTS: Overall, 70% of patients (N = 28) were found to have a DIS psychiatric disorder. There were differences in improvement between patients with and without Axis I disorders and between those with and without Axis II disorders. The presence of a diagnosis was associated with significantly lower improvement rates (p <.05). CONCLUSION: Patients with chronic pain enrolled in this clinic had a high prevalence of comorbid psychiatric disorders, and these comorbid patients were less likely to improve with standard chronic pain treatment. In a population of patients seeking treatment for chronic pain, these results suggest a need for detection and diagnosis of psychiatric disorders and further research on the efficacy of psychiatric treatment interventions in chronic pain management.
