Effects of socio-demographic variables on health-related quality of life determined by the quality of life index--German version.

STUDY OBJECTIVE: The purpose of this study was to determine subjective health-related quality of life (HRQoL) in a sample of the Austrian population over 14 years of age in order to evaluate the effect of socio-demographic variables on HRQoL. DESIGN/SETTING: HRQoL was determined by means of the quality of life index-German version (QLI-Ge). The influence of socio-demographic variables on HRQoL was assessed by statistical analysis using the Kruskal-Wallis test and an analysis of variance. PARTICIPANTS: A random-quota procedure was used to get balanced representation from regions and demographic groups of the Austrian population. The sample consisted of 1049 participants, 493 men and 556 women. MAIN RESULTS: Age was found to influence the QLI-Ge total score (index score) and most individual items, with increasing age resulting in a decrease in HRQoL. Differences between the sexes were observed in three dimensions: males scored higher in 'physical well-being', 'psychological well-being' and 'occupational functioning'. Marital status impacted most items with married persons showing better values than divorced persons or singles. Profession had only a minor effect on HRQoL, the level of education showed no influence at all. CONCLUSIONS: The socio-demographic variables age, sex and objective living conditions had a major influence on subjectively rated HRQoL, whereas profession and education were found to play a minor role in this context. It is recommended that in the interpretation of studies assessing HRQoL the above-mentioned objective factors be considered. This will be of particular importance when determining the effect of a pharmacotherapy on HRQoL in patients.

Pharmacophilia and pharmacophobia: determinants of patients' attitudes towards antipsychotic medication.

OBJECTIVE: To identify factors that influence attitudes towards psychopharmacological treatment in patients suffering from schizophrenia and schizoaffective psychoses. METHODS: Ninety-two participants in an outpatient psychoeducational program, classed as "pharmacophobic" or "pharmacophilic" according to the Drug Attitude Inventory scale, were compared with regard to sociodemographic variables, clinical characteristics, subjective deficit syndrome, illness concepts, knowledge, locus of control, and quality of life. RESULTS: The 59 pharmacophilic and the 33 pharmacophobic patients did not differ significantly with regard to most sociodemographic variables, symptoms, or classic personality traits such as locus of control, self-concept, and quality of life. The only differences concerned hospitalization history ( P < 0.05) and statements on the actual, subjective experience of desired and undesired effects of medication ( P < 0.01). CONCLUSIONS: The impact of subjective experiences with drug treatment on attitudes towards medication and compliance needs to be a main focus of interventions targeting attitudes towards pharmacological treatment.

The long-term course of panic disorder--an 11 year follow-up.

BACKGROUND: The purpose of this study was to assess the naturalistic long-term course of panic disorder over a period of 11 years. METHOD: Thirty DSM-III-R panic disorder patients, who had suffered from panic disorder for 6 years on average and who had taken part in an 8-week multicenter drug trial, were included in the intent-to-follow-up group to be reinterviewed 11 years after the end of the trial. At baseline and at follow-up the same instruments were used to assess frequency of panic attacks, level of phobic avoidance, and disabilities. Treatments received during the follow-up period and attempted suicides were assessed with a structured interview. Periods of well-being during the follow-up period were elicited retrospectively with a specifically designed longitudinal chart. RESULTS: Twenty-four patients could actually be reinterviewed after 11.3 years. While at baseline all patients had suffered from panic attacks and had been severely disabled on a number of measures, 66.7% had no panic attack during the year before follow-up. During the month before follow-up 87.5% had no panic attack, and 54% showed no or only mild phobic avoidance. In the areas of work and family life 90% showed no or only mild disabilities, whereas in the area of social life this percentage was lower (67%). Thirty-three percent of the patients were completely remitted according to a composite remission criterion. CONCLUSIONS: Panic disorder is not a uniformly chronic and progressing disorder. Over a period of 11 years there is a good chance of recovery from panic attacks and disabilities, and full remission is also possible.

Sleeping habits in the Austrian population.

OBJECTIVES: To gain reliable data on sleeping habits and sleep disturbances of the Austrian population. BACKGROUND: Exact data on sleeping habits are of interest in relation to assessment of sleep disturbance-related illnesses and general social processes. METHODS: A prospective, cross-sectional study was performed with recruitment of a representative sample of 1049 Austrians (aged 15-82 years), according to the Federal Statistics population characteristics. Interviews were conducted in the households of the participants by specially trained interviewers of an institute for empirical research. RESULTS: Men consider their quality of sleep to be significantly better than women (P=0.00234), and younger persons consider their quality of sleep to be significantly better than older persons (P=0.00001). In comparison, women and people over the age of 50 report worse subjective sleep quality, worse sleep efficiency, more difficulty in falling asleep and sleep maintenance, more apneic events, more pathologic limb movements, more daytime dysfunction, and more intake of sleeping medication. Other sociodemographic factors influence sleep reports to a lesser extent. CONCLUSIONS: Subjectively disturbed sleep (prevalence in the total population 24.9%), excessive hypnotic drug intake (prevalence 13.0%), and daytime dysfunction (prevalence 17.4%) are a widespread problem, especially in women and older people. With increasing life expectancy in Western societies, the prevalence of sleep disturbances will increase.

[Application of a context-oriented model for the planning of psychotherapy].

Since clinical experience has shown that creating a therapeutic setting with borderline or psychotic patients is extremely difficult the Department of Psychoanalysis and Psychotherapy at Vienna University Hospital has developed a method of treatment designed to increase the possibilities to work with this group of patients. This procedure is conceptualised as "context oriented model exploration in psychotherapy planning" COMEPP. Initially the context is explored in which the psychotherapeutic model should be implemented which has so far failed for different reasons. Following this a setting is created in which the therapeutic team and the patient(s) can constructively and creatively reflect on alternative therapeutic models. A clinical case illustrates the problems and the basic structure of COMEPP in a schematic and condensed form.

[Cognitive dysfunction in schizophrenic psychoses. Drug and psychological treatment choices].

Primarily from the perspective of psychopharmacology, schizophrenic symptomatology has recently been dichotomized into "plus" and "minus" symptoms, although the role of cognitive dysfunctions has been regarded as particularly important for the diagnosis since the time of Eugen Bleuler. Many studies show that schizophrenic patients suffer consistently from cognitive dysfunction. Among these, are impairments of attention and memory functions as well as executive functions such as planning and problem solving. These impairments are stable or progressive and often continue into the remission phase of schizophrenia and impair both social integration as well as occupational performance. In this overview, research results on cognitive dysfunction in patients with schizophrenic illnesses and their relation to psychosocial disabilities are described first. The therapeutic value and possible clinical-practice implications of atypical anti-psychotics and various cognitive therapy methods are then presented. Methodological weaknesses and open questions, both pharmacological and with regard to cognitive interventions, are discussed.

Sleep and quality of life in the Austrian population.

PURPOSE: To compare the self-reported estimation of sleep quality evaluated by the Pittsburgh Sleep Quality Index (PSQI) and life quality assessed by the Quality of Life Index (QLI). BACKGROUND: The PSQI comprised 19 questions and assessed a wide variety of factors relating to sleep quality. The QLI consisted of 10 items for self assessment of different dimensions of life quality. SUBJECTS: A representative Austrian sample (n = 1049) aged above 15 years. PROCEDURE: Interviews in the homes of the participants. RESULTS: 32.1% could be classified as poor sleepers (37% females, 26.5% males). Sleep quality decreased with increasing age, especially in women. Overall quality of life was highest in younger (15-29 years) and lowest in elderly subjects (over 50 years). Life quality decreased with increasing age. Between subjective sleep quality and quality of life a moderate, significant correlation was found (r2= 0.6721). CONCLUSIONS: Complaints about a bad quality of sleep could be used as a screening method in the exploration of patients' quality of life (QoL).

Schizophrenia and quality of life.

OBJECTIVE: The purpose of this paper is to examine critically results of quality-of-life research in schizophrenic patients living in the community. METHOD: Based on the relevant literature results of specific studies are discussed in the light of the methodological problems of assessing quality of life in these people. RESULTS: Subjectively assessed quality of life was found to be higher in the less educated and in female patients, and when a sense of control is experienced. If negative or extrapyramidal symptoms are experienced and stigmatization is perceived, subjective quality of life is reported as being poorer. These results are discussed in view of the additional needs and fewer resources of this population, their stigma-dilemma and their occasional difficulties in adequately assessing quality of life. CONCLUSION: It is argued that subjective and quantitative measures of quality of life in schizophrenic patients should be supplemented by external assessment and qualitative methods.

Are commonly used self-report inventories suitable for screening postpartum depression and anxiety disorders?

OBJECTIVE: The utility of several self-report symptom inventories were examined for detecting postpartum depression (MDD) and anxiety disorders (AD). METHOD: Fifty women (3 or 6 months postpartum), at heightened risk for MDD, completed several depression and anxiety symptom checklists. Psychiatric diagnoses were obtained via SCID interview. RESULTS: Rates of MDD (n=9) and AD (n=9) were equivalent in this sample, with minimal diagnostic overlap. While all the self-report depression inventories screened accurately for MDD, none discriminated AD sensitively and reliably. CONCLUSION: The frequent occurrence of AD emphasizes the need to identify appropriate screening instruments for postpartum anxiety disorders.

The long-term course of panic disorder and its predictors.

Whereas lifetime prevalence rates of panic disorder--as established in epidemiologic surveys--range between 1.6 and 3.5%, 1-month rates usually amount to much less than one half of the lifetime rates. This finding indicates that a substantial proportion of patients who had panic disorder at some stage in their life must have remitted. In contrast to these results, clinicians tend to regard panic disorder as a chronic condition because, as a rule, they see panic patients only several years after onset of the disorder. A number of small, prospective, long-term studies of such clinical populations indicate that after several years, between 17 and 70% of patients still have panic attacks, and between 36 and 82% have phobic avoidance. In the largest and longest follow-up study published to date, 45% of all patients showed an unremitting--although in a certain proportion waxing and waning--course, 24% followed a pattern of remissions and relapses, whereas 31% went back into a stable remission. The evidence of factors predicting the course of panic disorder in clinical populations suggests that long duration and agoraphobia at baseline--not the severity and frequency of panic attacks--are predictors of an unfavorable course. Additional studies are needed to determine whether personality factors, depression, and other variables are also of predictive relevance. Also, factors working during follow-up, such as positive and negative life events, coping behaviors, and treatment, should be considered in future studies.

[Patient suitability for discharge from psychiatric hospitals].

OBJECTIVE: To assess the possibility of discharging psychiatric inpatients of two large Mental Hospitals in Lower Austria. METHODS: A point prevalence study was performed in 1992. Treating psychiatrists were asked to evaluate the possibility to discharge patients under the hypothetical assumption that a broad range of residential facilities were available. RESULTS: The inpatient proportion had decreased from 2179 in 1974 to 1032 in 1992. Of the 1992 population 75.7% might be discharged. Most patients (41.5%) were regarded as needing a permanently staffed home. CONCLUSIONS: Although the inpopulation of the two large Mental Hospitals studied had decreased over a period of 18 years already by over 50 percent, the results of this study show that there is a large potential for further reform. Since the evaluation was carried out by the treating psychiatrists in the hospital, who might have been in a conflict of interests or might have preferred the treatment they are providing themselves, this finding is particularly remarkable.

[Rehabilitation in schizophrenia--guidelines for including psychosocial measures].

Today schizophrenic patients live most of their life outside institutions. Social relationships and their quality have, therefore, become practically important. However, they are ambiguous in nature: they can mean a stress for the patient, but they can also be used for therapeutic purposes. It has been shown in many treatment studies, that the combination of psychosocial and medication strategies can improve the long-term outcome of schizophrenia. It is contended that the inclusion of the patient and his or her relatives as partners improves outcome.

Embarrassment about the first panic attack predicts agoraphobia in panic disorder patients.

In order to find out whether contextual variables of the first panic attack and the person's reaction to it predict the development of agoraphobia in panic disorder patients, 60 patients with a DSM-III-R diagnosis of panic disorder with agoraphobia and 30 patients suffering from panic disorder without agoraphobia were interviewed about their first panic attack. Single comparisons between groups of agoraphobic and non-agoraphobic patients were carried out and a logistic regression model was applied. Occurrence of the first panic attack in public and the feeling of embarrassment were found to be significantly associated with the development of agoraphobia. It is concluded that eliciting this specific form of social concern at an early stage might help to identify patients at risk for later agoraphobia, which could, in turn, help to further specify early therapeutic interventions and concentrate therapeutic efforts on a high-risk group of panic disorder patients.

A study of the effects of patient anxiety, perceptions and equipment on motion artifacts in magnetic resonance imaging.

We investigated to see if motion artifacts (MA) occurring in magnetic resonance imaging (MRI) are related to prescan anxiety measures and test the feasibility of identifying patients at risk for the development of MA before scanning. Furthermore, to determine a possible influence of constructional differences between a 1.5 and a 0.5 tesla scanner on the frequency of MA. Two hundred and ninety-seven first time MRI patients were surveyed before and after imaging with anxiety and attitude questionnaires. Frequency and impact on diagnostic quality of MA were documented. 12.8% of all scans showed MA not related to normal body pulsations. In 6.4% the diagnostic quality was impaired. Constructional differences did not influence the frequency of MA. Also, anxiety as determined with the most common anxiety measuring instrument was not related to the development of MA. Concern about the technical apparatus identified 70.6% of all individuals developing MA. Patients at risk for the development of MA can be identified prior to scanning. It seems necessary to further develop reliable methods to detect them and to evaluate strategies to prevent MA.

[The first panic attack: a missed chance for prevention of panic disorder and its complications].

OBJECTIVE: Assessment and analysis of first medical consultations and their significance in panic disorder patients. METHODS: 90 panic disorder patients were interviewed concerning their experiences with the medical system at the time of their first panic attack. RESULTS: Panic disorder patients contacted mostly non-psychiatric medical services at the time of their first panic attack. The correct diagnosis was established in only 4 cases (5.6%). CONCLUSIONS: An important chance for secondary prevention of the development of panic disorder is missed, probably due to the poor education of physicians on panic attacks.

High frequency of EEG and MRI brain abnormalities in panic disorder.

The frequency and quality of brain abnormalities in panic disorder (PD) were assessed with magnetic resonance imaging (MRI). The use of electroencephalography (EEG) to detect PD patients with a high probability of morphologic brain abnormalities was also explored. Consecutive PD patients (n = 120) were screened with routine EEG examinations and were divided into the following subgroups on the basis of their EEG findings: patients with non-epileptic EEG abnormalities (EEG-A group, n = 28), matched patients with normal EEG results (EEG-N group, n = 28) and matched healthy controls (n = 28). PD patients showed a higher than expected rate of non-epileptic EEG abnormalities (29.2%; 35 of 120). EEG screening was effective in identifying patients with a high probability of morphologic brain abnormalities. MRI abnormalities were found in 60.7% of the EEG-A patients, 17.9% of the EEG-N patients, and only 3.6% of the controls. A high frequency of septo-hippocampal abnormalities was found. Further research should focus on attempts to subtype PD on the basis of neuroanatomic and functional brain abnormalities.
