Development and validation of the Environmental Confinement Stressors Scale (ECSS-20).

The COVID-19 pandemic has generated a global crisis with severe consequences for public health. There have been negative impacts on people's quality of life and mental health due to various stressors arising in this context, such as physical, social, economic, and psychological challenges. Noteworthy among these are the indirect effects of health measures, especially social distancing and confinement, which have significantly altered people's daily lives and social activities, producing high levels of anxiety, depression, and stress.

Naive skepticism scale: development and validation tests applied to the chilean population.

Background: Skepticism has traditionally been associated with critical thinking. However, philosophy has proposed a particular type of skepticism, termed naive skepticism, which may increase susceptibility to misinformation, especially when contrasting information from official sources. While some scales propose to measure skepticism, they are scarce and only measure specific topics; thus, new instruments are needed to assess this construct.

Construction and validation of a scale of sexual self-concept for the elderly Chilean population.

Background: Sexual self-concept has a central role in the life of the elderly population. Indeed, their sexual self-concept has significant and positive relationships with their satisfaction with life, pleasure, and willingness to interact with others. However, social-cultural prejudice means that the elderly are considered asexual individuals, harming their sexual self-concept.

Jealousy, sexism, and romantic love myths: the role of beliefs in online dating violence.

With the massification of the Internet and social networks, a new form of dating violence called cyber-violence has emerged, which involves behaviors of control, humiliation, intimidation and threats towards the partner or ex-partner. Using a non-probabilistic sample of 1,001 participants aged 18 to 25 years, the present study used an , retrospective, cross-sectional, single-group design to analyze the joint effects that beliefs associated with dating violence such as romantic love myths, jealousy, and sexism have on the victimization and perpetration of cyber-violence. The results evidenced that jealousy is involved in both Cyber-victimization and Cyber-harassment perpetrated, while sexist beliefs are only involved in perpetration.

Comparison of false positive and false negative rates of two indices of individual reliable change: Jacobson-Truax and Hageman-Arrindell methods.

Background: Quantification of change is crucial for correctly estimating the effect of a treatment and for distinguishing random or non-systematic changes from substantive changes. The objective of the present study was to learn about the performance of two distribution-based methods [the Jacobson-Truax Reliable Change Index (RCI) and the Hageman-Arrindell (HA) approach] that were designed for evaluating individual reliable change.

Methods: A pre-post design was simulated with the purpose to evaluate the false positive and false negative rates of RCI and HA methods.

Development of a Scale to Measure Healthy Behaviors in Spanish-Speaking University Students.

Chronic non-communicable diseases (NCDs) are a public health problem that affect the quality of life and well-being of people, especially the youth, who have been identified as a high-risk population. Physical inactivity is a key risk factor for NCDs, and an unhealthy diet is a significant driver of NCDs. On the other hand, physical exercise and healthy habits are effective methods of prevention.

Internalized homophobia and sexual risk behavior in men who have sex with men: The mediational role of sexual self-concept.

Men who have sex with men (MSM) are one of the populations most likely to be infected with human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) worldwide. Sexual risk behaviors (SRB) are the main route of HIV transmission. Among the factors associated with SRB, internalized homophobia (rejection of one's sexuality) is a risk factor unique for MSM.

Psychological Factors and Sexual Risk Behaviors: A Multidimensional Model Based on the Chilean Population.

Human immunodeficiency virus (HIV) is a global health problem, with sexual risk behaviors (SRB) being the main routes of spreading the virus. Evidence indicates that different psychological factors influence SRB (e.g.

Flourishing Scale: Adaptation and Evidence of Validity in a Chilean High School Context.

This study aimed to adapt the Flourishing Scale to a Chilean high school context and provide evidence of its validity. Data were collected from 1,348 students (52% girls) from three different Chilean schools. The results of confirmatory factor analysis (CFA) supported a one-factor solution, multiple-group CFA supported gender invariance, and structural equation model indicated that the FS is related to positive and negative academic feelings.

School Burnout Inventory: Factorial Validity, Reliability, and Measurement Invariance in a Chilean Sample of High School Students.

This brief report assessed the psychometric validity and gender invariance of the School Burnout Inventory (SBI) -a measure of students' exhaustion, cynicism, and inadequacy- in a convenience sample of 972 high school Chilean students ranging between 12 and 18 years old. The results showed that: (1) the SBI produces adequate scores in terms of reliability; (2) two models (one solution of three related factors and one of second-order and three first-order factors) fitted adequately fit to our sample and was invariant across gender; and (3) the SBI scores were significantly related to other related constructs (i.e.

Development and Evidence of the Validity of the Condom Use Attitudes Scale for Youth and Adults in a Chilean Context.

Condom use is the most effective preventive behavior against HIV transmission, and its inadequate use is a public health problem that occurs mostly among youth and young adults. Although there are scales that measure condom use, those that exist correspond to English-speaking developments or do not have psychometric evidence to support them, so it is possible that the available adaptations of instruments do not adequately reflect the phenomenon in the Chilean population. Thus, the study aims to develop a scale to assess attitudes toward condom use in Chilean youth and young adults.

Correction: Development and evidence of validity of the HIV risk perception scale for young adults in a Hispanic-American context.

[This corrects the article DOI: 10.1371/journal.pone.

Development and evidence of validity of the HIV risk perception scale for young adults in a Hispanic-American context.

HIV/AIDS is a public health problem that is transmitted through risky sexual behavior. The literature suggests that the perception of HIV risk is a motivator for the prevention of risky sexual behaviors. There is no culturally adapted scale to assess HIV risk perception in the Hispanic-American population.

Development and validity evidence of the multidimensional scale of sexual self-concept in a Spanish-speaking context.

Background/objective: STIs and HIV/AIDS are an important public health problem, transmitted by risky sex behaviours. In this context, it is necessary to identify protective factors, of those behaviours, as sexual self-concept. Sexual self-concept is a multidimensional trait (i.

Three-factor structure for Epistemic Belief Inventory: A cross-validation study.

Research on epistemic beliefs has been hampered by lack of validated models and measurement instruments. The most widely used instrument is the Epistemological Questionnaire, which has been criticized for validity, and it has been proposed a new instrument based in the Epistemological Questionnaire: the Epistemic Belief Inventory. The Spanish-language version of Epistemic Belief Inventory was applied to 1,785 Chilean high school students.

Rumination in posttraumatic stress and growth after a natural disaster: a model from northern Chile 2014 earthquakes.

Background: Traumatic experiences, such as natural disasters, produce multiple and serious impacts on people. Despite the traditional focus on negative consequences, in many cases there are also positive consequences, such as posttraumatic growth. Tedeschi and Calhoun proposed a model of posttraumatic growth that emphasizes the role of rumination after the basic beliefs breakdown due to the occurrence of a traumatic experience.
