The Schuhfried VTS enables computer-assisted application of a large number of highly diverse psycho-diagnostic tests and measuring procedures. In developing the system much emphasis was placed on transparent structure and largely uniform design. It is therefore simple to operate and easy to understand and does not require any special computer skills.
The VTS basic module is required for administration of any of the available tests.
The Schuhfried VTS supports the administration of both single tests and test batteries. Many of the single tests are available in different test versions. These test versions may differ, for example, in terms of test duration or difficulty or may be parallel forms. They are characterized by different parameters reflecting specific test requirements. They have been designed for administration to a specific population (e.g. psychiatric patients, children, etc.) or for special measuring purposes (e.g. repeated measurements). Test batteries are compiled from the available single tests and test versions.
Rasch-homogeneous questionnaire that assesses the effects, the functions and the subjectively felt symptoms of alcohol consumption and estimates the risk of alcohol abuse.
The questionnaire assesses the positively felt mental effect and social function of alcohol. This questionnaire is applicable to all respondents who have experiences with alcohol. It gives indications on respondents at risk in a preliminary stage of dependency, and recognizes alcoholism by the extent of the positively felt effects of alcohol. In addition, the FFT supplies reliable information on counseling and therapy in individual cases, with little effort.
Main areas of application: Clinical psychology, health psychology, and psychotherapy.
The FFT is based on results of social-cognitive and learning-theoretical alcoholism research, which has to some extent also entered the concepts of recidivism independency. What is specially emphasized is the individual amplifier value of alcohol in case of a lack of alter- native strategies. Items from 17 different function areas of alcohol can be categorized in 5 scales scaled according to the Rasch model to assess
The FFT is one of the few questionnaires that are homogeneous in the sense of the Rasch model. During the construction the use of questions that can cause denial tendencies in alcoholics (e.g. questions about the amount of alcohol) was avoided deliberately.
The items of the FFT are presented in sequence on the monitor. The subject always has to choose one out of four alternative answers on a fixed rating scale.
There are two long forms with 93 items (present and past) and a standard short form (present without scale 5) with 64 items. There is a possibility to select individual scales in the test manager window.
The following variables are presented: "Excitatory effect of alcohol", "psychopharmacological effect of alcohol", "sociodynamic function of drinking", "exploiting a social context", and "symptoms of mental and physical dependency". Additionally a discriminant score is calculated, which estimates a value for the risk of alcohol abuse. An item analysis protocol can be issued that presents the answers to the individual statements.
The reliabilities (Cronbach's Alpha) for the 5 scales lie between r=.87 and r=.96 Measurement precision is given due to the validity of the Rasch model for all 5 scales. Due to the proven unidimensionality of the test, scaling fairness can be deemed as given. This means that the various groups of people are not systematically put at a disadvantage or favored concerning individual items.
Even without taking into account scale 5, the FFT separates normal drinkers from respondents dependent on alcohol with the utmost certainty. Apart from that profile differences are proved depending on gender, age, type of dependency and the degree of chronification.
The standardization of test forms S1-S3 refers to scores of N=244 alcohol dependent abstinent patients from 12 different in-patient and outpatient treatment centers and N=95 subjects with normal alcohol consumption from the research laboratory of the company SCHUHFRIED GmbH. In addition, norms of N=98 people who were apprehended for bad driving behavior and collected during driving diagnostics of INFAR are available. Furthermore a norm sample of N=284 persons, collected in the research laboratory of Schuhfried GmbH in the year 2003, is available for test form S3.
