    Adaptation and psychometric characteristics of a scale to evaluate ageist stereotypes
    (ELSEVIER IRELAND LTD, 2020) Rosell Cisternas, Javiera; Verges, Alvaro; Torres Irribarra, David; Flores, Karina; Gomez, Macarena
    Objectives: Negative ageism impacts on the well-being of older persons; therefore, its identification is important to generate interventions that allow its decrease. CENVE is a widely used instrument to evaluate stereotypes towards old age in Spanish. However, its factor structure in older population and its invariance between those over and under 60 years old have not been confirmed. The objectives of the study are to evaluate the psychometric properties of the instrument and its invariance by age and gender. Methods: The total sample was 439 people with 54 % of people over 60. This was divided into two random subsamples. With the first subsample, a confirmatory factor analysis of the different models proposed was carried out until an adequate fit was achieved, which was confirmed with the second subsample. Then, the invariance of the instrument was evaluated with the total sample by age and gender. Results: The revised CENVE consists of 15 items with a unifactorial structure that showed good psychometric properties. It presented good reliability, including a .92 Omega. In addition, it proved to be an invariant instrument according to age and gender, which allows comparison between groups. Discussion and Implications: The use of CENVE will allow the identification of ageist stereotypes, with which interventions can be carried out to reduce them, both in groups older and younger than 60. In addition, it can be useful to generate a discussion about ageism in different fields, such as professional training.

    Motives of Use and Internet Addiction: Development and Evidence of Validity of a Scale to Evaluate Motives of Internet Use
    (2022) Rosell Cisternas, Javiera; Verges, Álvaro; Torres Irribarra, David; Sepúlveda Caro, Sofía Valeria; Flores, Karina
    The motives for Internet use are crucial to understanding why people get and stay online despite negative consequences. This study aimed to develop and evaluate the psychometric properties of a questionnaire of Internet use motives in Spanish and its relationship with Internet addiction. The sample (N = 417) was divided into two subsamples: the first one used to perform a confirmatory factor analysis and the second one to cross-validate the retained model. Multi-group analysis by age and gender yielded evidence of invariance. The final questionnaire contains 20 items with a 5-factor structure with good psychometric properties. Finally, a structural equation model was fitted to evaluate the relationship between motives of Internet use and Internet addiction, in which a significant association was observed between coping, enhancement, and utility motives with Internet addiction. The questionnaire of Internet use motives (MUI) is useful to get reliable evaluation of motives for Internet use in Spanish-speaking population.
