Validierung eines Messinstrumentes zur Bestimmung von Informationsverhalten : die Miller Behavioral Style Scale 2011-03-24T10:13:26Z Klier, Andreas Klier, Andreas deposit-license application/pdf 2005 deu 2011-03-24T10:13:26Z Validation of a questionnaire to determine informationseeking - the Miller Behavioral Style Scale This diploma thesis examines the psychometric properties of<br />the Miller Behavioral Style Scale (MBSS), a psychological questionnaire.<br />The test is<br />designed to identify the tendency to seek or avoid<br />information concerning a threatening and uncontrollable event.<br />Voluminous information induces stress to some people while it<br />reduces it for others.<br />Therefore, it is often used in medical settings.<br />The questionnaire consists of four stress-evoking scenarios (dentist,<br />terrorist, dismissal and airplane), each followed by eight coping<br />options of which four are measuring information seeking ("monitoring") and four<br />representing distraction ("blunting").<br />Three scores can be derived: a total monitoring score, a total blunting score<br />and a total difference score.<br /><br />The coping measure is widely used.<br />Despite the common usage of the scale, the psychometric<br />properties are often found deficient. The internal consistency,<br />especially of the blunting sub-scale, is<br />problematic and the construct and criterium validity is seldom<br />confirmed.<br /><br />Conceptional and methodological shortcomings of the construct<br />information seeking under threat can be a reason. Section<br />2 summarizes these problems: Thus, the dimensionality of the construct<br />is not clear. Furthermore, it is not clarified if information<br />seeking is situation-specific or not.<br /><br />In the subsequent<br />chapter the reliability of the<br />questionnaire is tested in an internet setting. The findings<br />confirm the poor results especially for the blunting sub-scale.<br />An item analysis identifies problematic items supposably<br />responsible for these outcomes.<br /><br />The predictive validity is tested by presenting one half of the participants<br />of Study 1 with a threatening and the other half with a non-threatening<br />scenario. Here, they could obtain additional information about the scenario.<br />No connection could be made between the score on the questionnaire<br />and the amount of information obtained. Additionally, the degree of the threat<br />did not influence the information behaviour.<br /><br />Whether internet usage and education is an influential factor for<br />information seeking in the questionnaire is tested in a non-internet<br />setting. This could not be confirmed. Moreover, not only the internal consistency<br />for the blunting sub-scale was found problematic but also for the monitoring sub-scale.<br /><br />According to the present findings further usage of the<br />questionnaire is not recommended.
