A video protocolling and retrieval system for the analysis of behaviour. Rec~nt developments in the data processing and video technologies have enabled the desIgn of automatic systems for the handling of video software. The system for the protocoIling and retrieval of audiovisual data (PRA VDA) described here has been developed for applications in behavioural observation and analysis. The facilities available, including time coding, search routines and automatic editing are explained and the advantages of computer aided operation are dealt with. Current applications of the system are briefly discussed.

Introduction Although symptomatic therapy is available for Parkinson's disease, patients and relatives are faced with continuous severe psychological problems. These psychological problems include: 1. lack of emotional expression, 2. bradephrenia, 3. depression, 4. lack of motivation,S. social anxiety, 6. stress induced increase of symptoms. The first four of these may be at least in part due to the dopamine deficiency. However, even as part of the primary symptoms they have social and communicative impact for patients and relatives. Social anxiety and stress induced increase of symptoms on the other hand clearly result from an interaction of somatic and psychological factors. Social anxiety mainly develops in Parkinson I s disease as an indirect consequence of the motor symptoms. Patients are afraid of being negatively evaluated in the public, of receiving negative comments etc. Thus r social withdrawal increases and the improvement of neurological symptoms following drug treatment may not be fully exploited on the psychosocial level. Stress induced increase of motor symptoms is a commonly observed phenomenon in Parkinson's disease. Even minor stressors, mainly social in nature, can have extreme effects and may elicit or increase tremor or rigidity. A patient can be well in one moment, but unable to move in the next when being aware that he has to leave the house in an hour. Given this situation, patients and relatives have to develop strategies fo~ an emotional balance in the presence of a continuous confrontation with the direct and indirect consequences of the disease. A precondition for developing new psychologically based strategies is an optimwn medical treatment. The integrated approach for neurological and psychological support has the following goals: 1. improving medical treatment for the individual patient, 2. improving psychological coping and psychosocial adaptation for patients and relatives, and 3. evaluating and improving medical and psychological therapy. CONCLUSION Psychological intervention can provide considerable help for a substantial part of Parkinson patients. The main target is coping with stressful social situations. Relaxation and cognitive restructuring together with situational behavioral analysis and training of social skills specifically adapted to the disease are" the main strategies. Various problems remain open at the moment, like the maintenance of motivation which is especially critical for Parkinson patients. Parkins on 's disease is a neurological disease with a known pathological substrate and a therapy which is effective at least for several years on a symptomatic level. The symptoms are tightly connected with psychological emotional and cognitive processes. Moreover, patients and relatives have to cope with symptoms which strongly influence social interaction. And they have to cope together with this situation over a period of ten or twenty years. Thus not only for the patient but also for the health of the relatives, psychological aid is urgently needed. We suggest to integrate psychological approach into the neurological diagnosis and treatment.
Der vorliegende Beitrag behandelt inhaltliche und methodische Probleme einer Längsschnittstudie, die derzeit am MPI für Psychiatrie in München an depressiven Patienten durchgeführt wird. Diese Untersuchung hat einen diagnostischen und einen kommunikationstheoretischen Aspekt. Von diagnostischem Interesse sind die depressionsspezifischen Veränderungen des kommunikativen Verhaltens. Kommunikationstheoretisch gewendet lautet die Frage, wie sich der interne Zustand einer Person in ihrem Verhalten reflektiert. In diesem Beitrag wird die Fragestellung konzentriert auf tonische Eigenschaften des Blickverhaltens im Interaktionsprozeß und deren Stabilität im Krankheitsverlauf. Zunächst wird die theoretische Grundlage referiert, die wir für das Blickverhalten entwickelt haben. Im zweiten Abschnitt wird auf Datenerhebung und Reliabilitätskontrolle eingegangen. Die Struktur der Daten bestimmt die Auswertungsmethoden. Einige der Methoden, mit denen wir derzeit arbeiten, werden im Zusammenhang mit umschriebenen Problemstellungen erläutert: Deskription und Interpretation des tonischen Blickverhaltens depressiver Patienten im Krankheitsverlauf (Abschnitt 3). Zusammenhang der individuellen Blickniveaus von Interaktionspartnern (Abschnitt 4) Deskription eines Dialogs (Interviews) als Sequenz von distinkten Zuständen. In den Zuständen werden Sprech- und Blickverhalten beider Interaktionspartner miteinander kombiniert (Abschnitt 5) Analyse der intraindividuellen Wechselwirkung zwischen Blick- und Sprechverhalten (Abschnitt 6). Die Abschnitte 3 mit 6 werden durch vorläufige Ergebnisse illustriert.

Validität und Reliabilität der Sprechkodierung einer Beobachtergruppe wurden in Abhängigkeit von der zeitlichen Auflösung untersucht. Die Validität wurde anhand der Übereinstimmung der Beobachter mit einem automatischen Sprachdetektor berechnet. Die Reliabilitätswerte für die Kodierung von Sprechen und Blikken ergaben sich aus der Übereinstimmung der Beobachter untereinander. Im wesentlichen zeigten sich folgende Ergebnisse: 1. Die Validität/Reliabilität der Sprechkodierung ist eine monotone, nichtlineare Funktion der gewählten Auflösung. Die systematischen Fehler, die auf Latenz und Trägheit der menschlichen Beobachter zurückgehen, werden bei einer Auflösung von 400 msec nahezu vollständig unterdrückt. 2. Weder bei der Erfassung des Sprech- noch des Blickverhaltens lassen sich Anzeichen für Observer-Drift feststellen. Trainierte und untrainierte Beobachter unterscheiden sich nicht signifikant. 3. Die Kodierung des Sprechverhaltens ist geringfügig reliabler als die des Blickverhaltens. Dieser Unterschied kann in der Praxis vernachlässigt werden.
In accordance with various other studies. the present longitudinal study gave no clues for specific personality variables or traits 01' drug addicts. Personality factors did not allow a valid prediction of the kind 01' th~apy termination. nor were there clear deviations from the norm. Analyzed as a group. the addicts showed only minor changes that appeared over the course of treatment. These results correspond to data reported on alcohol dependency (cf. Wanke 1987). A more differentiated picture is gained when stable and changeable components of personality and analyzed separately. Changeable components are of special relevance for treatment. From the current study these were characteristics of action regulation, that is, activation and impulse control, social interaction, and somatic reactions (sleep disorders, bodily reactions to drug deprivation). For relapse prevention, attention should be given to stable, persistent, problematic components. Persistent suicidal ideas turned out to be one such aspect. Like the differentiation between state and trait anxiety, stable and variable components could also be separated for other domains of personality when they are used to describe the course of treatment. How can personality concepts and instruments for assessment be utilized for treatment? The claim of therapists to predict the outcome of a treatment may be realized for only a delimited period of time. Especially at such critical points as shortly before relapse, a firm prediction might be possible only rarely (Wanke 1987). Lack of predictability could be a warning which, however, can be verified only afterward. According to the current results, one benefit of personality concepts could be to specify targets of change on an individual basis and thus clarify effects of therapeutic interventions. Personality concepts can help patients to better understand their problems and to recognize changes as weil as persistent areas of vulnerability.
