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