Predictors of response to Systems Training for Emotional Predictability and Problem Solving (STEPPS) for borderline personality disorder: an exploratory study.

OBJECTIVE: Few predictors of treatment outcome or early discontinuation have been identified in persons with borderline personality disorder (BPD). AIM: The aim of the study was to examine the relationship between baseline clinical variables and treatment response and early discontinuation in a randomized controlled trial of System Training for Emotional Predictability and Problem Solving, a new cognitive group treatment. METHOD: Improvement was rated using the Zanarini Rating Scale for BPD, the Clinical Global Impression Scale, the Global Assessment Scale and the Beck Depression Inventory. Subjects were assessed during the 20 week trial and a 1-year follow-up. RESULTS: Higher baseline severity was associated with greater improvement in global functioning and BPD-related symptoms. Higher impulsivity was predictive of early discontinuation. Optimal improvement was associated with attending > or = 15 sessions. CONCLUSION: Subjects likely to improve have the more severe BPD symptoms at baseline, while high levels of impulsivity are associated with early discontinuation.

Children of parents with obsessive-compulsive disorder -- a 2-year follow-up study.

OBJECTIVE: To examine the association between parental obsessive-compulsive disorder (OCD) and emotional and behavioural disorders in offspring. METHOD: Demographic, clinical, and diagnostic data were collected from parents with OCD, control subjects, and their respective offspring. Offspring were reassessed at a 2-year follow-up. RESULTS: Probands with OCD and controls were relatively well matched for age, gender, race, educational rating, and marital status. Offspring of OCD probands were at greater risk than offspring of controls for dimensionally measured anxiety, depression, somatization, and social problems. OCD offspring were significantly more likely than control offspring to have lifetime overanxious disorder, separation anxiety disorder, OCD, or 'any anxiety disorder'. Female gender in the parent with OCD, evidence of family dysfunction, and high symptom levels in offspring were predictive of broadly defined OCD at follow-up. CONCLUSION: Children having a parent with OCD are more likely than control offspring to have social, emotional, and behavioural disorders.

Compulsive buying disorder: definition, assessment, epidemiology and clinical management.

Compulsive buying disorder is characterised by excessive or poorly controlled preoccupations, urges or behaviours regarding shopping and spending, which lead to adverse consequences. Compulsive buying disorder has been estimated to affect from 2 to 8% of the general adult population in the US; 80 to 95% of those affected are female. Onset occurs in the late teens or early twenties, and the disorder is generally chronic. Psychiatric comorbidity is frequent, particularly mood, anxiety, substance use, eating and personality disorders. Treatment has not been well delineated, but individual and group psychotherapy, cognitive-behavioural therapy and 12-step programmes may be helpful. Debt consolidation and credit counselling will be appropriate for many individuals who have compulsive buying disorder. Serotonin (5-hydroxytryptamine; 5-HT) re- uptake inhibitors may help some patients regulate their buying impulses. Self-help books are also available.

The Iowa follow-up of chemically sensitive persons.

Clinical symptoms and self-reported health status in persons reporting multiple chemical sensitivities (MCS) are presented from a 9-year follow-up study. Eighteen (69%) subjects from a sample of 26 persons originally interviewed in 1988 were followed up in 1997 and given structured interviews and self-report questionnaires. In terms of psychiatric diagnosis, 15 (83%) met DSM-IV criteria for a lifetime mood disorder, 10 (56%) for a lifetime anxiety disorder, and 10 (56%) for a lifetime somatoform disorder. Seven (39%) of subjects met criteria for a personality disorder using the Personality Diagnostic Questionnaire-IV. Self-report data from the Illness Behavior Questionnaire and Symptom Checklist-90-Revised show little change from 1988. The 10 most frequent complaints attributed to MCS were headache, memory loss, forgetfulness, sore throat, joint aches, trouble thinking, shortness of breath, back pain, muscle aches, and nausea. Global assessment showed that 2 (11%) had "remitted", 8 (45%) were "much" or "very much" improved, 6 (33%) were "improved", and 2 (11%) were "unchanged/worse". Mean scores on the SF-36 health survey showed that, compared to U.S. population means, subjects reported worse physical functioning, more bodily pain, worse general health, worse social functioning, and more emotional-role impairment; self-reported mental health was better than the U.S. population mean. All subjects maintained a belief that they had MCS; 16 (89%) acknowledged that the diagnosis was controversial. It is concluded that the subjects remain strongly committed to their diagnosis of MCS. Most have improved since their original interview, but many remain symptomatic and continue to report ongoing lifestyle changes.

Indoor environmental quality in six commercial office buildings in the midwest United States.

The aims of this study were to characterize physical, mechanical, and environmental factors influencing indoor environmental quality (IEQ) in commercial office buildings; document occupant perceptions and psychosocial attributes; and evaluate relationships among these parameters. Six large office buildings in metropolitan areas were selected in Iowa, Minnesota, and Nebraska. Comprehensive sampling was conducted over one week in each building, during all four seasons. This paper presents the study methods and selected results from the first round of sampling (November 1996 to April 1997). Air flow and recirculation rates were quite variable, with the proportion of outdoor air provided to occupants ranging from 10 to 79 CFM/person. Carbon dioxide, carbon monoxide, and temperature were within ranges anticipated for nonproblem buildings. Relative humidity was low, ranging from 11.7 to 24.0 percent. Indoor geometric mean concentrations of total volatile organic compounds (TVOCs) ranged from 73 to 235 microg/m3. The most prevalent compounds included xylene, toluene, 2-propanol, limonene, and heptane. Geometric mean formaldehyde concentrations ranged from 1.7 to 13.3 microg/m3, and mean acetaldehyde levels ranged from <3.0 to 7.5 microg/m3. Airborne concentrations of culturable bacteria and fungi were low, with no samples exceeding 150 CFU/m3. Total (direct count) bioaerosols were more variable, ranging from 5010 to 10,700 organisms/m3. Geometric mean endotoxin concentrations ranged from 0.5 to 3.0 EU/m3. Respirable particulates (PM10) were low (14 to 36 microg/m3). Noise levels ranged from 48 to 56 dBA, with mean light values ranging from 200 to 420 lux. Environmental parameters were significantly correlated with each other. The prevalence of upper respiratory symptoms (dry eyes, runny nose), central nervous system symptoms (headache, irritability), and musculoskeletal symptoms (pain/stiffness in shoulders/neck) were elevated compared to other studies using similar questionnaires. Importantly, psychosocial factors were significantly related to increased symptoms in females, while environmental factors were more closely correlated with symptoms in males. Endotoxin concentrations were associated with symptoms in both males and females. These data will help to identify and quantify the relative role of factors that contribute to sick building syndrome. The data collected in this study may also be used to evaluate the effectiveness of current building operation practices, and can be used to prioritize allocations of resources for reduction of risk associated with IEQ complaints.

The relationship of mental disorders and idiopathic environmental intolerance.

Idiopathic environmental intolerance (IEI) is an acquired condition with multiple symptoms associated with diverse environmental factors tolerated by most persons, not explained by known medical or psychiatric disorders. Data from clinical and epidemiologic samples show a robust association between IEI and lifetime psychiatric disorder, particularly mood, anxiety, somatoform, and personality disorders. IEI has not been associated with lifetime substance use disorders or psychotic disorders. The relationship of IEI and psychiatric disorder is important to acknowledge because it alerts clinicians to the fact that many persons diagnosed with IEI suffer treatable emotional illnesses, and because it suggests that some persons with mental illness are being misdiagnosed when their symptoms are misinterpreted as evidence of IEI.

A nine-year follow-up of people diagnosed with multiple chemical sensitivities.

The authors assessed self-reported health status and clinical symptoms in people reporting multiple chemical sensitivities (MCS) at a 9-year follow-up interview using structured and semistructured instruments and self-report questionnaires. Of the original sample, 18 people (69%) consented to an interview. By use of the best estimate diagnostic method, 15 subjects (83%) met DSM-IV criteria for a lifetime mood disorder, 10 (56%) for a lifetime anxiety disorder, and 10 (56%) for a lifetime somatoform disorder. None of the subjects met the criteria for a substance use disorder (current or lifetime). The Illness Behavior Questionnaire and the Symptom Check-list-90-Revised results showed little change from 1988 and remained significantly different from the control group on many subscales. The authors conclude that the subjects remain strongly committed to the diagnosis of MCS, and although improved since their original interview, many remain symptomatic and continue to report ongoing lifestyle changes.

Multiple chemical sensitivity syndrome: symptom prevalence and risk factors in a military population.

OBJECTIVE: To assess the prevalence of and risk factors for self-reported symptoms suggestive of multiple chemical sensitivities/idiopathic environmental intolerance (MCS/IEI) in Persian Gulf War (PGW) veterans from Iowa and a comparison group of PGW-era military personnel. METHODS: A population-based sample of Iowa military personnel was surveyed using a cross-sectional telephone interview. Study participants were randomly drawn from 1 of 4 domains: PGW active duty, PGW National Guard/Reserve, non-PGW active duty, and non-PGW National Guard/Reserve. A complex sample survey design was used selecting participants from the following substrata: age, sex, race, rank, and military branch. The criteria for MCS/IEI were developed using expert consensus and the medical literature. RESULTS: A total of 3695 study participants (76% of those eligible) completed the telephone survey. The prevalence of symptoms suggestive of MCS/IEI in all participants was 3.4%. Veterans of the PGW reported a significantly higher prevalence of symptoms suggestive of MCS/IEI than did non-PGW military personnel (5.4% vs 2.6%); greater sensitivity to organic chemicals, vehicle exhaust, cosmetics, and smog; and more lifestyle changes. The following risk factors for MCS/IEI were identified with univariate analysis: deployment to the Persian Gulf, age (>25 years), female sex, receiving a physician diagnosis of MCS, previous professional psychiatric treatment, previous psychotropic medication use, current psychiatric illness, and a low level of preparedness. Multiple logistic regression analysis identified several independent risk factors for MCS/IEI, including deployment to the Persian Gulf, age, sex, rank, branch of service, previous professional psychiatric treatment, and current mental illness. CONCLUSIONS: Self-reported symptoms suggestive of MCS/IEI are relatively frequent in a military population and are more common among PGW veterans than comparable controls. Reported chemical sensitivities and accompanying behavioral changes were also frequent. After adjusting for age, sex, and training preparedness, previous professional psychiatric treatment and previous psychotropic medication use (before deployment) showed a robust association with symptoms suggestive of MCS.

Multicenter double-blind comparison of sertraline and desipramine for concurrent obsessive-compulsive and major depressive disorders.

BACKGROUND: Serotonin reuptake inhibitors (SRIs) have demonstrated consistent efficacy in the treatment of obsessive-compulsive disorder (OCD), while agents that are primarily norepinephrine reuptake inhibitors have not. Comparable efficacy has been demonstrated for SRI and non-SRI antidepressants in uncomplicated major depressive disorder (MDD). This multicenter trial is the first comparison of an SRI (sertraline) and a non-SRI antidepressant (desipramine) in the treatment of OCD with concurrent MDD. METHODS: One hundred sixty-six patients diagnosed using structured clinical interviews and recruited from 16 treatment sites were randomly assigned to double-blind treatment with either sertraline (up to 200 mg/d) or desipramine (up to 300 mg/d) over 12 weeks. Measures of severity of OCD and MDD symptoms, as well as adverse effects of the medications, were monitored over the course of the treatment period. RESULTS: Patients assigned to sertraline responded significantly better at end point on measures of OCD and MDD symptoms compared with patients assigned to desipramine. Sertraline was also associated with a significantly greater number of patients who achieved a "robust" improvement in OCD symptoms (> or =40% reduction) compared with desipramine. More patients receiving desipramine than sertraline discontinued treatment because of adverse events. CONCLUSIONS: The SRI sertraline was more effective in reducing MDD and OCD symptoms than the primarily norepinephrine reuptake inhibitor desipramine for patients with concurrent OCD and MDD.

A double-blind comparison of fluvoxamine versus placebo in the treatment of compulsive buying disorder.

Nondepressed outpatients with a compulsive buying disorder were recruited by advertisement and word of mouth for inclusion in a controlled treatment trial. Following a 1-week single-blind placebo washout, subjects were randomly assigned to fluvoxamine (n = 12) or placebo (n = 11). Subjects received fluvoxamine (up to 300 mg daily) or placebo for 9 weeks. There were few dropouts. Outcome measures included the Yale-Brown Obsessive-Compulsive Scale--Shopping Version (YBOCS-SV), three Clinical Global Impressions (CGI) ratings, the Hamilton Rating Scale for Depression (HRSD), and the Maudsley Obsessive-compulsive Inventory (MOI). At the conclusion of the trial, 50% of fluvoxamine recipients and 63.6% of placebo recipients achieved CGI ratings of "much" or "very much" improvement, while 33% of fluvoxamine recipients were "very much" improved compared with 18% of placebo recipients (by endpoint analysis). Subjects in both treatment cells showed improvement as early as the second week of the trial, and for most, improvement continued during the 9-week study. There were no significant differences between fluvoxamine- and placebo-treated subjects on any of the outcome measures, with the exception that fluvoxamine recipients achieved greater improvement than placebo recipients on the MOI (p = .02). Adverse experiences were more frequent in the group receiving fluvoxamine, particularly nausea, insomnia, decreased motivation, and sedation. We conclude that in a short-term treatment trial of compulsive buying, subjects receiving fluvoxamine or placebo respond similarly.

The epidemiology and phenomenology of compulsive sexual behavior.

Compulsive sexual behavior (CSB) is characterized by inappropriate or excessive sexual behaviors or cognitions that lead to subjective distress or impaired functioning. Both abnormal (paraphilic) and conventional (nonparaphilic) forms of sexual behavior are usually included in the definition. CSB is reported to affect 3% to 6% of the general population in the United States, occurring more frequently in men. It typically begins in the late teens or early twenties and is chronic or intermittent. The disorder has been described as a progression through four stages: preoccupation, ritualization, gratification, and despair. Men with CSB typically focus on physical sexual gratification; women focus on romantic or emotional aspects of sexuality. Psychiatric comorbidity is common, particularly substance use, mood, anxiety, and personality disorders. CSB can lead to medical complications. Risk factors are thought to include family history and childhood abuse.

Sexual disorders not otherwise specified: compulsive, addictive, or impulsive?

Paraphilias are recurrent and intense sexually arousing fantasies, sexual urges, or behaviors generally involving nonhuman objects. These paraphilias cause the suffering or humiliation of the patient or patient's partner, or children, or other nonconsenting persons. However, in many patients symptoms involve more culturally acceptable patterns (eg, repetitive masturbation, Internet pornography); such hypersexual symptoms have been labeled as compulsive, addictive, or impulsive. Growing evidence supports the existence of a discrete syndrome characterized by recurrent and intense sexually arousing fantasies, sexual urges, or behaviors involving patterns that fall outside the definition of paraphilia. There is, however, high comorbidity with paraphilia. While such symptoms have been labeled as sexual compulsion or addiction, these terms are problematic in this context. Modern nosology has neglected this entity, although the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), category of sexual disorders not otherwise specified includes hypersexual behaviors as an example. We suggest that the DSM-IV category of sexual disorders be modified to include explicitly diagnostic criteria for a disorder characterized by hypersexual symptoms involving patterns that fall outside of the current definition of paraphilia. The disorder might be classified as one of the paraphilias, or as paraphilia-related. In the absence of a comprehensive understanding of the pathogenesis of this disorder, we suggest that it simply be termed hypersexual disorder.

Tardive dyskinesia: review of treatments past, present, and future.

The aim of this article is to review the theories purported to explain the pathophysiology of tardive dyskinesia (TD) and the various agents investigated for its treatment. The methods used included a review of studies in English, a Medline search, as well as a check of references listed at the end of the articles was conducted to obtain the relevant studies for review. The results show that vitamin E appears to be a promising agent both for the treatment and prophylaxis of TD. Complete remission has been reported with clozapine, but there is a need for further studies. There are cases reported of benefits with numerous miscellaneous agents, including electroconvulsive therapy, but there are no well-designed, substantiating studies. We conclude that there is no universally effective treatment for TD. Vitamin E is promising both for the treatment and possibly prophylaxis of TD. Clozapine therapy should be considered in patients refractory to traditional antipsychotics who develop TD. Judicious use of antipsychotics and periodic monitoring remain the cornerstone of therapy. None of the atypical antipsychotics (risperidone, olanzapine, clozapine, quetiapine) have been used long enough or adequately studied for their effects on TD.

Quality of life and health-services utilization in a population-based sample of military personnel reporting multiple chemical sensitivities.

We sought to assess quality of life and health-services utilization variables in persons with symptoms suggestive of multiple chemical sensitivity/idiopathic environmental intolerance (MCS/IEI) among military personnel. We conducted a cross-sectional telephone survey of a population-based sample of Persian Gulf War (PGW) veterans from Iowa and a comparison group of PGW-era military personnel. A complex sample survey design was used, selecting subjects from four domains: PGW active duly, PGW National Guard/Reserve, non-PGW active duty, and non-PGW National Guard/Reserve. Each domain was substratified by age, gender, race, rank, and military branch. The criteria for MCS/IEI were developed by expert consensus and from the medical literature. In the total sample, 169 subjects (4.6%) of the 3695 who participated (76% of those eligible) met our criteria for MCS/IEI. Persons who met the criteria for MCS/IEI more often reported the following than did other subjects: more than 12 days in bed due to disability, Veteran's Affairs disability status, Veteran's Affairs disability compensation, medical disability, and unemployment. MCS/IEI cases also had higher outpatient rates of physician visits, emergency department visits, and inpatient hospital stays. Subjects who met the criteria for MCS/IEI more often reported impaired functioning on each Medical Outcomes Study 36-Item Short Form subscale, compared with those who did not meet the criteria. We concluded that although the diagnosis of MCS/IEI remains controversial, the persons who met our criteria for the disorder are functionally impaired.

Cigarette smoking and psychiatric disorder in a community sample.

We examined the lifetime prevalence of psychiatric disorders in cigarette smokers and nonsmokers in a non-patient sample. First-degree relatives of psychiatric patients (n = 697) and normal controls (n = 360) were interviewed with the Diagnostic Interview Schedule and the Structured Interview for DSM-III Personality Disorders. Using these interviews we diagnosed the major mental (Axis I) disorders and personality (Axis II) disorders. A cigarette smoker was defined as someone who smoked daily for a month or more at some time in their lives. We found that smokers more frequently had a lifetime history of major depression, alcohol and drug abuse/dependence, agoraphobia, unstable/acting out and anxious/fearful personality disorders. In a logistic regression analysis, the only significant variables independently associated with smoking status were the alcohol and drug use disorders. Age was an important modifying variable--the smoking-illness relationship was robust in the youngest age cohort and negligible in the oldest cohort. We conclude that cigarette smokers have increased rates of mood, anxiety, substance use, and personality disorders. However, after controlling for the comorbidity among the disorders only alcohol and drug abuse/dependence were independently associated with smoking. Young smokers had particularly high rates of substance use disorders. This age effect may reflect the impact of a quarter century of health education.

Psychiatric illness in the first-degree relatives of persons reporting multiple chemical sensitivities.

The multiple chemical sensitivities (MCS) syndrome is characterized by unexplained physical and psychiatric complaints attributed by patients and some of their physicians to low-level chemical exposures. In this study, we interviewed 15 subjects with MCS and 21 controls about their first-degree relatives using the Family History-Research Diagnostic Criteria (FH-RDC). Subjects with MCS were more likely than controls to report their relatives to have major depression, alcoholism, panic disorder, obsessive-compulsive disorder, and antisocial personality disorder. They were also likely to have past suicide attempts, and to have received some form of psychiatric treatment (hospitalization, medication or electroconvulsive therapy, or counseling). Nearly 30% of the relatives of subjects with MCS were reported to have MCS themselves. Possible reasons for the findings are discussed.
