title: [Participation refusal by probands in an epidemiologic long-term study--sociodemographic, clinical and psychometric findings].
abstract: Usually little is known about probands who participated in an epidemiological longitudinal field survey but refused participation in follow-up investigations. For reasons of data protection and on account of the fact that investigative instruments used in longterm field surveys or panel studies are more focused on well defined issues (opinions, attitudes, assessment of behaviors) and less on personality variables, differentiated statements on probands who explicitly refused cooperation can hardly be made. In our epidemiological longitudinal field study on prevalence and course of psychogenic disorders we have a different situation. Within the limits of our study we had the unique opportunity to gain far-reaching information on probands who refused to participate in preceding investigations in regard to sociodemographic, psychometric and clinical variables. The clientele of refusers we present in our paper mainly comprises elderly, married, rather obsessive-compulsive structured, lower-class females. According to our data interactive aspects are equally responsible for reduced cooperativeness. The significance of our findings for the planning and carrying out of epidemiological longitudinal field surveys is discussed.
