Summary
The Basque version of the Generalized Problematic Internet Use Scale-2 (GPIUS-2) is a reliable tool for assessing problematic internet use in adults and adolescents. It shows good validity and can help professionals evaluate this growing issue.
Area of Science:
- Psychology
- Public Health
- Digital Well-being
Background:
- Problematic Internet Use (PIU) is a growing concern in developed nations.
- PIU is characterized by excessive, disproportionate, or inappropriate Internet engagement.
- This leads to distress, significant time consumption, and impaired functioning in life domains.
Purpose of the Study:
- To adapt the Generalized Problematic Internet Use Scale-2 (GPIUS-2) into Basque.
- To evaluate the psychometric properties of the Basque version of the GPIUS-2.
- To provide a reliable assessment tool for problematic Internet use in the Basque-speaking population.
Main Methods:
- The study involved two independent samples: adults (n=283) and adolescents (n=943).
- Confirmatory factor analysis was used to test one-dimensional, five-factor, and four-factor models.
- Invariance testing was conducted across gender and age groups.
Main Results:
- Both four-factor and five-factor models demonstrated adequate fit indices, with the four-factor model selected for parsimony.
- The Basque GPIUS-2 showed measurement invariance across men and women, and adults and adolescents.
- Subscale scores correlated positively with Internet addiction and moderately with depression, anxiety, and stress.
Conclusions:
- The Basque version of the GPIUS-2 is a valid and reliable instrument.
- It is suitable for assessing problematic Internet use in both adult and adolescent populations.
- This tool will aid professionals in identifying and addressing problematic Internet use in the region.

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

01:27Coping Strategies: Problem Focused

Coping strategies are methods people use to manage, tolerate, or reduce the effects of stressors. These strategies involve both behavioral and psychological actions to handle stressful situations. One common approach is problem-focused coping, which aims to change or eliminate the source of stress rather than merely addressing its consequences. This method involves taking direct action to resolve the issue causing stress.
