Romanian Version of the Internet Addiction Test: Psychometric Properties and Cross-Gender Invariance

Psychometric validation of Young's Internet Addiction Test among Chinese undergraduate students

The global prevalence of internet addiction is escalating annually and uncontrollable use of the internet can cause significant physical and psychological damage. Young's Internet Addiction Test (IAT), widely utilized across diverse cultures, has demonstrated structural inconsistencies in previous research, with some items requiring refinement. This study aimed to validate the IAT among Chinese undergraduate students and assess its psychometric properties. The IAT's structure was initially explored through Exploratory Factor Analysis (EFA) using pilot study data (n=376), with internal consistency and test-retest reliability (n=96) evaluated. Subsequently, Confirmatory Factor Analysis (CFA) was conducted using data from the actual study (n=1042) to confirm the structure. Results showed that a three-factor solution explained 61.29% of the total variance with a satisfactory model fit (χ2/df = 4.382, RMSEA = 0.057, CFI = 0.952, TLI = 0.943, SRMR = 0.045, AIC = 798.755) and psychometric properties, validating the IAT's utility for future investigations of internet addiction in Chinese undergraduates. Notably, a high prevalence of moderate internet addiction was observed within the sample, highlighting the significance of this issue in the target population and emphasizing the need for further research and potential interventions.

Short video addiction scale for middle school students: development and initial validation

The rise of short video platforms has increased concerns about addiction, especially among adolescents. This study aimed to develop a Short Video Addiction Scale for middle school students. A sample of 1492 middle school students participated in the study. Initial items were derived from qualitative interviews and refined through psychometric analyses, including Exploratory and Confirmatory Factor Analyses. The final scale, consisting of 15 items across five factors (Academic Procrastination, Interpersonal Strain, Social Communication Difficulties, Attention Concentration Difficulties, and Impaired Control over Short Video Use), demonstrated high internal consistency (Cronbach's α = 0.900), test-retest reliability, and strong validity. The Short Video Addiction Scale, a 15-item scale, demonstrates robust psychometric properties. It is reliable and valid for assessing short video addiction among middle school students and will be a valuable tool for identifying and addressing the growing concerns of short video addiction in adolescents.

Psychometric evaluation of the internet addiction test in India

The Internet Addiction Test is a widely used assessment of symptoms of internet addiction. Although originally proposed as assessing different components of internet addiction, research has been mixed in terms of its factor structure. This study is the first to examine the psychometric properties of the IAT in an Indian population. A large sample (N = 2700) of Indians living in the Southern city of India were recruited door-to-door and completed the IAT and other validity measures. In Study 1, an exploratory factor analysis (n = 1375) indicated a one-factor structure, with 13 items measuring symptoms of internet addiction. This short-form IAT showed construct and convergent validity by correlating with higher daily internet use, higher scores on measures of problematic internet gaming, social media use, and smartphone use, and functional impact. In Study 2, confirmatory factor analysis (n = 1375) indicted this one-factor structure was a good fit to the data, and the correlations with validity measures were replicated. This short-form IAT appears to be valid as a measure of one underlying factor of problematic internet use in young Indian adults.

The Six-Item Version of the Internet Addiction Test: Its Development, Psychometric Properties, and Measurement Invariance among Women with Eating Disorders and Healthy School and University Students

Internet addiction (IA) is widespread, comorbid with other conditions, and commonly undetected, which may impede recovery. The Internet Addiction Test (IAT) is widely used to evaluate IA among healthy respondents, with less agreement on its dimensional structure. This study investigated the factor structure, invariance, predictive validity, criterion validity, and reliability of the IAT among Spanish women with eating disorders (EDs, N = 123), Chinese school children (N = 1072), and Malay/Chinese university students (N = 1119). In school children, four factors with eigen values > 1 explained 50.2% of the variance, with several items cross-loading on more than two factors and three items failing to load on any factor. Among 19 tested models, CFA revealed excellent fit of a unidimensional six-item IAT among ED women and university students (χ2(7) = 8.695, 35.038; p = 0.275, 0.001; CFI = 0.998, 981; TLI = 0.996, 0.960; RMSEA = 0.045, 0.060; SRMR = 0.0096, 0.0241). It was perfectly invariant across genders, academic grades, majors, internet use activities, nationalities (Malay vs. Chinese), and Malay/Chinese female university students vs. Spanish women with anorexia nervosa, albeit it was variant at the scalar level in tests involving other EDs, signifying increased tendency for IA in pathological overeating. The six-item IAT correlated with the effects of internet use on academic performance at a greater level than the original IAT (r = -0.106, p < 0.01 vs. r = -0.78, p < 0.05), indicating superior criterion validity. The six-item IAT is a robust and brief measure of IA in healthy and diseased individuals from different cultures.

Problematic Internet Usage and Self-Esteem in Chinese Undergraduate Students: The Mediation Effects of Individual Affect and Relationship Satisfaction

The aim of this cross-sectional study was to examine the mediating effects of individual affect and relationship satisfaction on the relationship between self-esteem and Problematic Internet Use (PIU). Affect was measured using the Positive and Negative Affect Schedule (PANAS), relationship satisfaction was assessed using a positive and negative semantic dimension scale, self-esteem was measured using the Rosenberg Self-Esteem Scale, and PIU was measured using the Problematic Internet Use scale with a sample of 507 Chinese university students (Mage = 20.41 years, SD = 2.49). The relationships between the variables were tested using structural equation modelling with a multiple mediation model. The results revealed that negative affect and the negative semantic dimensions of relationship satisfaction mediated the relationship between self-esteem and PIU. The implications of the results and the study’s theoretical contributions are discussed.

A comparison using standardized measures for patients with irritable bowel syndrome: Trust in the gastroenterologist and reliance on the internet

BACKGROUND

Irritable bowel syndrome (IBS) patients' use of the Internet for health information interacts with the way they trust their gastroenterologist. No standardized measure has targeted IBS patients and gastroenterologists specifically, nor their use of the Internet. The aims of this paper were as follows: the development of a scale that measures an IBS patient's trust in their gastroenterologist, the development of a scale measuring an IBS patient's reliance on Internet health information, and testing the hypothesis that IBS patients, who use the Internet for IBS-related information, trust their gastroenterologist less than those who do not.

METHOD

A total of 82 patients (mean age 49, SD = 14.62) diagnosed with IBS completed two questionnaires: one about trust in their gastroenterologist and the other about the reliance on Internet health information regarding IBS. The two questionnaires were built using current literature as well as our previous qualitative research. The statistical computations were performed using the SPSS 20 program.

KEY RESULTS

Both questionnaires proved to be reliable in measuring gastroenterologist-IBS patient trust (alpha = 0.87) and Internet information reliance (alpha = 0.88), respectively. The IBS patients who did not look for information about IBS over the Internet had significantly higher trust in their gastroenterologist compared with those who did (U = 535.5; z = -2.26; P < 0.05).

CONCLUSIONS

We developed two ready-to-use scales to measure both the gastroenterologist-IBS patient's trust and the IBS patient's reliance on the Internet. Further studies will be able to explore the interaction among all variables in IBS patients' trust.

Assessing the Psychometric Properties of the Internet Addiction Test in Peruvian University Students

The use of the Internet has been gradually and unstoppably gaining ground in all areas of life, from recreational activities to how social relations are established. However, the existence of clinical cases indicates that the addictive use of the Internet is a problem that seriously affects some people. Among the instruments that measure this construct, the Internet Addiction Test (IAT) stands out. However, instrumental studies of this test are scarce in Latin America. The present study sought to analyze the psychometric properties of the IAT in a sample of 227 Peruvian undergraduate university students. Confirmatory factor analysis was used to provide validity evidence based on the internal structure, and evidence based on the relationship with other variables was also provided. Reliability was estimated through the ordinal alpha coefficient. The results indicated that the IAT adequately fits a bifactor model (with two specific factors, time/control and stress/compensate), obtaining good levels of reliability. Additionally, the IAT scores correlate significantly with the average number of hours per day on the internet and social skills. The results lead to the conclusion that the scores in the IAT have evidence of validity and reliability for its use.

A review of recent research in problematic internet use: gender and cultural differences

The present study reviewed current trends in the literature on problematic Internet use. The review included a total of 48 studies published within the last two years and covered by the Web of Science and Scopus databases. Despite frequently investigated in the literature, results of the studies suggest that there is still much to be unveiled regarding problematic Internet use and its relation to gender and cultural differences. In terms of gender, although more studies show that men are further vulnerable to problematic Internet use symptoms, results differ regarding the moderator effect(s) or differences in various cultural settings. Recent studies mostly employed quantitative methods; but, it is also noted that problematic Internet use studies increasingly focus on meta-analysis and literature reviews. Research also tends to investigate large-sample cross-cultural groups, but their results are far from achieving consensus. Studies mostly used cross-sectional approaches with self-report instruments and focused on adolescents and young adults who were students.

Homo Interneticus—The Sociological Reality of Mobile Online Being

The digitalization of everyday life has become a common place reality for more than half of the global population. Being connected 24/7 on several devices, being only one click/touch away from a huge amount of digital content, being available for interactions with almost any users from around the globe have become routine. In this paper, we identify the main sociological dimensions of the so-called Homo interneticus—a new manifestation of the human condition—on the basis of new communication technologies. The main research question was: Is time spent online a valid predictor of smartphone addiction? We conducted an experimental survey using a standard online questionnaire incorporating the Smartphone Addiction Scale—Short Version, followed by a request to upload screen captures recording respondents’ phone use during the previous week. We gathered 140 responses between May and July 2019. These were anonymously analyzed. The consistency between self-estimates and phone logs that we found gives encouragement for the development of this approach. A main finding is that the daily time spent on smartphone use is not in itself a strong predictor of addiction. Our research suggests that future studies should distinguish types of usage and investigate motivational springs.
