Internet gratifications and internet addiction: on the uses and abuses of new media.

Internet addiction has been identified as a pathological behavior, but its symptoms may be found in normal populations, placing it within the scope of conventional theories of media attendance. The present study drew upon fresh conceptualizations of gratifications specific to the Internet to uncover seven gratification factors: Virtual Community, Information Seeking, Aesthetic Experience, Monetary Compensation, Diversion, Personal Status, and Relationship Maintenance. With no parallel in prior research, Virtual Community might be termed a "new" gratification. Virtual Community, Monetary Compensation, Diversion, and Personal Status gratifications accounted for 28% of the variance in Internet Addiction Tendency. The relationship between Internet addiction and gratifications was discussed in terms of the formation of media habits and the distinction between content and process gratifications.

Relationships among Internet attitudes, Internet use, romantic beliefs, and perceptions of online romantic relationships.

The purpose of this study was to investigate factors relating to perceptions of online romantic relationships. One hundred seventy-seven people who had never been involved in an online romantic relationship completed a survey to assess relationships among perceptions of online romantic relationships and (a) amount of Internet use, (b) Internet affinity, (c) perceived realism of the Internet, and (d) romantic beliefs. Results reveal that amount of time spent online and affinity for the Internet are positively related to more favorable perceptions of online romantic relationships, whereas perceived realism and romantic beliefs were not related to perceptions of online romantic relationships. Romantic beliefs, therefore, may lend themselves to more conventional notions of relationships. Implications for and development and maintenance of online relationships, as impacted by social support networks, are discussed.

Munchausen by Internet: detecting factitious illness and crisis on the Internet.

Within the past few years, the Internet has exploded into a medium of choice for those interested in health and medicine. Along with the promise of immediate access to authoritative resources via websites, the Internet offers "virtual support groups" through formats such as chat rooms and newsgroups. These person-to-person exchanges, typically focusing on a specific topic, can be invaluable sources of information and compassion for patients and their families. However, individuals may misuse these Internet groups at times, offering false stories of personal illness or crisis for reasons such as garnering attention, mobilizing sympathy, acting out anger, or controlling others. I present four such cases and, based on experience with these and other cases of "virtual" factitious disorder and Munchausen by proxy, summarize indicators of factitious Internet claims and the reactions that participants usually experience once the ruse is recognized.

[Investigation for smoking cessation support on Internet. Internet survey of health and smoking awareness of users].

PURPOSE: This paper is intended as investigation of level of awareness of "health and smoking" of Internet users as a foundation to guide no smoking efforts on the Internet. METHODS AND SUBJECTS: A questionnaire was posted on a homepage only from September 1 to 30, 1999 only. RESULTS: There were 1687 valid responses. Respondents using a cellular phone with the Internet totaled 148. In reference to smoking, 47% of women and 54% of men replied when encountering "smoking by a stranger" that they were "a little troubled." As for "knowledge of medical treatment to stop smoking," over 70% of the respondents replied that they "only know it by name." In regards to responsibility of "who is wrong," respondents that answered "the country that is not regulated" were broken down into about 16% smokers and over 30% non-smokers. Personal computer users that are smokers accounted for 295 people, or 37.5%, and of the total respondents using a cellular phone with the Internet, 49 or 60.5% are smokers. Clearly these results are significant.

Secure HL7 transactions using Internet mail (Internet draft).

The document describes the applicability of the Internet standardisation efforts on secure electronic data interchange (EDI) transactions for Health Level-7 (HL7), an EDI standard for Healthcare used world-wide. The document heavily relies on the work in progress by the IETF EDIINT working group. It is in most parts a restatement of the EDIINTs requirements document and application statement 1 (AS#1) tailored to the needs of the HL7 audience. The authors tried to make the document as self consistent as possible. The goal is to give to the reader who is not a security or Internet standards expert enough foundational and detail information to enable him to build communication software that complies to the Internet standards. Even though the authors rely on and promote the respective Internet standards and drafts, they did not withstand from commenting on and criticising the work where they see upcoming problems in use with HL7 or other EDI protocols that have not been in the initial focus of the EDIINT working group. The authors make suggestions to add parameters to the specification of the MIME type for EDI messages in RFC 1767 in order to enhance functionality. The authors give use cases for a larger subset of disposition types and modifiers of message disposition notifications. One key issue where the document goes beyond the current EDIINT drafts is the concept of non-repudiation of commitment to an EDI transaction. Secure EDI transactions should be regarded as "distributed contracts," i.e. not only the sending and receiving of single messages should be non-refutable but also the connection between messages interchanges. In anticipation of this requirement HL7 usually requires a response message to be sent to acknowledge every transaction. The authors therefore have the requirement to securely couple an EDI response message to its request message. Given the current shape of RFC 1767 this is generally possible only if a response message is coupled with an MDN receipt and the combination of both signed by the responder. The document describes a protocol to bundle MDN and response that uses the MIME multi-part/related content type in RFC 2112.

Physical outcome measurements via the Internet: reliability at two Internet speeds.

We have developed a software application to enable interactive rehabilitation via the Internet. The reliability of the telemedicine application was examined by comparing it with face-to-face assessment. The physical outcome measures assessed were knee range of motion, quadriceps muscle strength, limb girth and an assessment of gait. One therapist performed both in-person and Internet-based measurements of all outcome measures on 20 normal subjects. There was good agreement between the two techniques (the 95% limits of agreement included zero for all the variables studied). Internet assessments were conducted at two bandwidths: ISDN at 128 kbit/s and the telephone network at 17 kbit/s. Bandwidth had no significant influence on any of the measures. This study suggests that Internet-based physiotherapy interventions delivered to the home are suitable for further development.

Collaboration using Internet for the development of case-based teaching files: report of the Computer and Instrumentation Council Internet Focus Group.

UNLABELLED: The Internet and particularly the World-Wide-Web is becoming a useful tool for the nuclear medicine community. METHODS: The Computer and Instrumentation Council of the Society of Nuclear Medicine convened an Internet Focus group to discuss collaboration using the Internet. The prototype application considered was development of case-based teaching files using the World-Wide-Web. Teaching file cases (clinical history, images, description of findings and discussion) on World-Wide-Web servers at different institutions are integrated using the Internet. The user can navigate from case to case using point-and-click hypertext linking. RESULTS: The initial experience with collaboration has been encouraging. An etiquette to help foster collaboration has been proposed. Development of quality control mechanisms and introduction of peer review were identified as issues needing further work. CONCLUSION: The World-Wide-Web offers great potential for new forms of collaboration. There is, however, a need to learn how to make best use of this new resource.

[Anesthesiologists and the Internet: the Internet and the Masui Discussion List].

The Internet is a global network that connects computer networks around the world. It enables inter-computer communication and the sharing of computer resources and information using the TCP/IP data transmission protocol. The Internet began in 1969 as the ARPAnet which connected just four computers, in California and Utah. On the Internet, computers are identified by their IP addresses and can exchange information with any other computers on the network. More than 120 Japanese anesthesiologists are subscribing to a mailing list, "the Masui Discussion List" on the Internet to exchange information with each other. They also send information to the world.

[Internet presence in surgical departments in Germany. II. Legal bases of medical Internet presence].

In recent years, the Internet has generally been growing throughout the world, and physicians have taken to the Web as well. Besides its use for medical data research, physicians and hospitals are increasingly discovering the Internet as a vehicle for the presentation of their scope of practice. In this regard, the legal frameworks in Germany are strictly regulated. This article presents current legal standards and consequences to be faced when the law on prohibited advertising is broken. Included are references to specific laws concerning Internet pages.

Screening for Internet addiction: an empirical study on cut-off points for the Chen Internet Addiction Scale.

The aim of this study was to establish the optimal cut-off points of the Chen Internet Addiction Scale (CIAS), to screen for and diagnose Internet addiction among adolescents in the community by using the well-established diagnostic criteria of Internet addiction. This survey of 454 adolescents used screening (57/58) and diagnostic (63/64) cut-off points of the CIAS, a self-reported instrument, based on the results of systematic diagnostic interviews by psychiatrists. The area under the curve of the receiver operating characteristic curve revealed that CIAS has good diagnostic accuracy (89.6%). The screening cut-off point had high sensitivity (85.6%) and the diagnostic cut-off point had the highest diagnostic accuracy, classifying 87.6% of participants correctly. Accordingly, the screening point of the CIAS could provide a screening function in two-stage diagnosis, and the diagnostic point could serve as a diagnostic criterion in one-stage massive epidemiologic research.

Validating internet research: a test of the psychometric equivalence of internet and in-person samples.

This study evaluated the psychometric equivalency of Web-based research. The Sexual Boredom Scale was presented via the World-Wide Web along with five additional scales used to validate it. A subset of 533 participants that matched a previously published sample (Watt & Ewing, 1996) on age, gender, and race was identified. An 8 x 8 correlation matrix from the matched Internet sample was compared via structural equation modeling with a similar 8 x 8 correlation matrix from the previously published study. The Internet and previously published samples were psychometrically equivalent. Coefficient alpha values calculated on the matched Internet sample yielded reliability coefficients almost identical to those for the previously published sample. Factors such as computer administration and uncontrollable administration settings did not appear to affect the results. Demographic data indicated an overrepresentation of males by about 6% and Caucasians by about 13% relative to the U.S. Census (2000). A total of 2,230 participants were obtained in about 8 months without remuneration. These results suggest that data collection on the Web is (1) reliable, (2) valid, (3) reasonably representative, (4) cost effective, and (5) efficient.

Internet resources for dentistry: utilization of the Internet to support professional growth, decision making, and patient care.

The use of computers as an information resource in dentistry has grown dramatically over the past ten years. Fueled by the availability of more powerful computers, societal acceptance of computer-based resources, and the development of the Internet, millions of documents now provide a tremendously important repository of information for healthcare providers. Those involved in delivery of dental care need to know how to access and use this information for their professional development and to support clinically related activities. This paper presents issues related to the use of the Internet. It also provides information on the use of search engines to find resources (websites) on the Internet and descriptions of some available resources of interest to those involved in oral healthcare.

Psychology of computer use: XLVII. Parameters of Internet use, abuse and addiction: the first 90 days of the Internet Usage Survey.

While the addictive potential of Internet usage is a topic that has attracted a great deal of attention, as yet little research has addressed this topic. Preliminary data from the Internet Usage Survey shows that most of the 563 users reported instances of Internet use interfering with other aspects of their lives, most commonly problems with managing time. A subgroup of users endorsed multiple usage-related problems, including several similar to those found in addictions. Younger users tended to have experienced more problems.

[Construction and operation of Internet Search Engine specialized in information on asthma. A Search Engine-based investigation to identify asthma-related information needed by Internet users].

To support asthmatic patients in collecting information through the Internet, we have constructed and operated a search engine specialized in asthma-related information making use of the search engine software available free of charge and other programs. A questionnaire was attached to the bottom of the Web page presenting the search results, asking the users to respond to several questions. During the three-year period since its start of operation on June 1, 2000, there was 66689 visits to this site and 786 responses to the questionnaire were collected. Of all respondents, 19.3% were medical professionals, 63.7% were patients or their family members, and 11.3% belonged to the other categories (5.3% did not specify their position). In each of these three user groups, only about half of the users were able to find a route to the information they needed. This seems to reflect the absence of adequate asthma-related information sources on the Internet in Japanese language. However, more than 70% of all users in each group answered that this search engine site was useful.
