Requirements for carrying out and evaluating computer-aided psychometric procedures:
• For the protection of personal data
• To control the test processing by restricting the authorized circle of users to qualified psychologists or persons under their supervision
• The existence of an automated or manual plausibility check of the entries
• The establishment of a direct contact with the subject (verification of the test comprehension …)
Limited contact possibilities to the subject:
Unfortunately, there are limited opportunities for internet-based examinations to contact the subject. Direct contact is less possible. There are, of course, feedback options via e-mail, but of course they depend on the personal initiative of the test person. It should be noted in a direct result feedback that any psychological impairments occurring can not be estimated and, of course, can not be influenced! In addition, an online earnings feedback in understandable
Be expressed in language. On an individual result feedback should be waived!
In principle, anonymity should also be guaranteed for Internet-based examinations, but according to data protection this anonymity is not sufficient, since the aspect of Internet-specific data transmission and storage of content and meta-information about data traffic is ignored! (Data packets go through several routers, which contain the data header with sender, recipient and further information)
Protection options would be e.g. the use of encryption programs, which are prohibited in some countries and for which it requires specific expertise and software.
It should also be noted here that the caching of e-mails on mailhost or www servers are monitored by persons, that is to say that these persons always have insight into the content data.
Setting up the system in a locked room and with controlled access and password-protected encryption of all data carriers with the help of special software products would be a good alternative for data protection or a solution.
Further advantages and developments of internet-based survey methods:
Meanwhile, it is even possible with the laptop the subject, e.g. To show film clips and have the material judged for an investigation. Further revolutionary are the three-dimensional scenarios or virtual worlds that can be shown to the subject. Subjects can almost really experience what they are portrayed by the almost “lifelike” possibility of representation.
Particularly interesting is the combination or comparison of surveys with data carriers (Disk by Mail, CD Rom) and Internet-based surveys.
What is a web experiment?
Basically, it can be said that web experiments are the logical extension of laboratory experiments with desktop computers. With the difference that the subject no longer needs to be present in a lab in person, but connects to the lab computer via a web browser, allowing him to participate in the experiment virtually anywhere in the world. With that we would already have the advantages of a web experiment:
– Easy accessibility of an almost inexhaustible group of test subjects: Due to the widespread use of the internet, test persons with different socio-demographic and cultural backgrounds can be reached. Psychological research is no longer limited to simply available populations. For example, if the group of psychology students has been used in many cases (which is controversial because psychologists make up only about 3% of the total population), then this restriction is no longer subject to Internet-based examinations.
