Generalized anxiety disorder and clinical worry episodes in young women.

BACKGROUND: This article presents epidemiological data on the prevalence of DSM-IV generalized anxiety disorder (GAD) and sub-threshold GAD (fulfilling three out of four GAD criteria) in young women together with data on co-morbidity and psychosocial functioning. The prevalence of clinically relevant worry and its predictive validity for the diagnosis of GAD were also examined. METHOD: Young women (N = 2064), aged between 18 and 25, from a representative German community sample were diagnosed with a structured clinical interview (ADIS-L, German research version). An additional interview questioned all the participants about the frequency/intensity and uncontrollability of diverse worry topics. RESULTS: Thirty-seven participants (1.8%) fulfilled the criteria of current GAD (1 week point prevalence) and 56 received a lifetime diagnosis (2.7%); a further 50 participants (2.3%) were diagnosed with sub-threshold GAD. Co-morbidity between GAD and other disorders was high for current (68%) and lifetime GAD (91%). GAD, as well as sub-threshold GAD, showed clearly reduced levels of psychosocial functioning. Whereas worries of low intensity and high controllability were ubiquitous in all subsamples, clinically defined worrying was rarely present in healthy subjects (0.89%) and of adequate predictive accuracy for GAD. CONCLUSIONS: Full GAD and sub-threshold GAD were moderately frequent in young women. Although DSM-IV worry criteria proved to be highly useful, the strictness of the complete GAD-criteria should not lead to absence of attention from subclinical generalized anxiety states in research and practice.

Characteristics of worry in GAD patients, social phobics, and controls.

Phenomenological features of worry such as thought content, subjective experience of worry, and efforts to control were investigated in the present interview study, as well as retrospective information about possible origins. To examine the clinical specificity of worrying in Generalized Anxiety Disorder (GAD), 36 GAD patients were compared to a normal control group (N = 30) and to a clinical control group (N = 22 social phobics). GAD patients differed from both groups in having higher frequency of worry, higher number of different worry topics, lower subjective controllability, more accompanying bodily symptoms, and more distress during worry. Thus, in general, our data confirm the central and specific role of worrying in GAD. Furthermore, in contrast to other topics, worrying about daily hassles was specific to GAD patients, which represents a lower threshold for starting to worry.

Obesity and mental illness in a representative sample of young women.

OBJECTIVE: To investigate the relation between mental disorders and weight, especially obesity. DESIGN: Epidemiological study of mental disorders with a representative sample of young women. SUBJECTS: A total of 2064 women, age 18-25 y, living in Dresden, Germany. MEASUREMENTS: Verbal reports of body mass index, structured clinical interview for psychological disorders. RESULTS: We found an association between psychological disorders and weight. Obese women had the highest rate of mental disorders overall, and they had higher rates of all subgroups of mental disorders, although many differences were not statistically significant. Most importantly, obese women suffered from an anxiety disorder significantly more often than women who were not obese. The observed differences were independent of socioeconomic status. CONCLUSIONS: In young women, obesity is related to increased rates of mental disorders, most notably anxiety disorders. Future longitudinal research will have to determine the causal relationships behind this correlation.

Explicit memory in anxiety disorders.

Two experiments were conducted to study selective memory bias favoring anxiety-relevant materials in patients with anxiety disorders. In the 1st experiment, 32 patients with generalized anxiety disorder (GAD), 30 with social phobia (speaking anxiety), and 31 control participants incidentally learned GAD-relevant words, speech anxiety-relevant words, strongly pleasant words, and words with a neutral valence. Participants did not show any explicit memory bias for threatening materials. Thirty patients suffering from panic disorder (PD) with agoraphobia and 30 controls took part in the 2nd experiment. The design was similar to the 1st experiment. This time a highly specific selective memory bias for threatening words was found. Words describing symptoms of anxiety were better recalled by PD patients. Results are consistent with previous findings but are inexplicable by existing theories.

A specific attentional bias in suicide attempters.

Selective attention in patients after an attempted suicide was investigated to find out whether a specific attentional bias for suicide-related materials exists and to clarify the possible role of emotions in the bias. Thirty-one patients who had previously attempted to commit suicide and 31 control participants took part in a modified Stroop task. The suicidal patients took significantly longer to name the colors of suicide-related words compared with other words, whereas color naming times of the control participants did not differ for suicide-related, neutral, positive, or negative words. Therefore, the attentional bias exhibited by suicidal patients was highly specific. There was no relation between the bias and measures of anxiety, depression, or hopelessness, whereas suicidal ideation correlated significantly with the attentional bias.

Update on the management of intestinal cryptosporidiosis in AIDS.

OBJECTIVE: To update readers on the pharmacotherapeutic management of cryptosporidiosis in patients with AIDS. DATA SOURCES: A MEDLINE search was used to identify pertinent literature. Additionally, programs and abstracts from the 33rd Interscience Conference on Antimicrobial Agents and Chemotherapy; the 1st International Conference on Macrolides, Azalides, and Streptogramins; the 93rd American Society for Microbiology Meeting; and the 6th and 7th International Conferences on AIDS were used. DATA EXTRACTION: Available data from in vitro, animal, and human experiments were reviewed. DATA SYNTHESIS: Intestinal cryptosporidiosis in patients with AIDS can be a life-threatening opportunistic infection. However, there can be significant variability in disease expression, including spontaneous remission. Supportive care with hydration and nutritional supplementation remains a hallmark of therapy. Unfortunately, there is no proven specific pharmacotherapy of cryptosporidiosis in patients with AIDS. Numerous agents have been analyzed for in vitro activity and efficacy in experimental animal models and actual human cases of the infection, including paromomycin, azithromycin, clarithromycin, octreotide, hyperimmune bovine colostrum, bovine transfer factor, and many others. Because limited numbers of controlled trials have been conducted with potential therapeutic agents, the majority of the information to date is preliminary in nature. CONCLUSIONS: Despite the availability of some evolving and potentially promising treatment modalities, further controlled clinical trials are necessary to evaluate the role of pharmacotherapy for intestinal cryptosporidiosis in patients with AIDS.

The emotional Stroop effect in anxiety disorders: general emotional or disorder specificity?

Selective attentional biases, often documented with a modified Stroop task, are considered to play an important role in the etiology and maintenance of anxiety. Two competing explanations for these effects are selectivity for highly emotional words in general vs. selectivity for disorder-specific words. We tested these explanations in 32 patients with generalized anxiety disorder (GAD), 29 patients with social phobia (SP), and 31 non-anxious controls. Stimuli were of four kinds: GAD-related words, SP-related words, words with a neutral valence, and words with a positive valence. Different attentional biases were observed: GAD patients were slowed by all types of emotional words, while SP patients were distracted specifically by speech-related words.

Don't worry and beware of white bears: thought suppression in anxiety patients.

The ability to suppress unwanted thoughts was investigated in patients with Generalized Anxiety Disorder (GAD; n = 29), Speech Phobics (n = 25), and nonanxious controls (n = 28). All participants spent 5 minutes thinking aloud about anything that came to mind while trying not to think of white bears. In another task, they thought aloud for 5 minutes while trying not to think of their main worry. Intrusions of unwanted thoughts were signaled by button presses and recorded on tape. In accordance with the disorder's definition and complaints of the GAD patients, they showed more intrusions of their main worry than of white bears. The opposite was true for other participants. Compared to a baseline measure, all participant groups were unable to reduce duration of main worry thoughts when trying to suppress them.
