Background: Validated measures of cyber dating violence are scarce and have barely explored the sexual dimension. The present study advanced this line of research by developing a new instrument that differentiates between sexual, verbal and control dimensions.

Method: The instrument was created in four phases: literature review, focus groups with young people, expert review, and creation of the final scale. This instrument was administered to 600 students from high schools in Seville and Córdoba, aged between 14 and 18 ( M = 15.54; SD = 1.22).

Results: A three-factor latent structure was confirmed for the aggression and victimization scales: verbal/emotional, control, and sexual. Using Item Response Theory, a refined version of the scales resulted in 19 items for both aggression and victimisation. Prevalence analysis showed that verbal/emotional forms were the most frequent, followed by control and sexual.

Conclusions: The CyDAV-T instrument can be considered a valid instrument for assessing cyber dating violence in the adolescent population.

Background: Previous studies show contradictory results regarding the bidirectional association between physical activity and nighttime sleep. The objective of the present study was to add knowledge to these possible relationships using autoregressive models.

Method: 214 adolescents (117 boys and 97 girls), with a mean age of 13.31 years agreed to participate. The study variables were measured with accelerometers for 7 full days over three consecutive years. The mlVAR package was used to compute estimates from multivariate vector autoregression models.

Results: The 5-delay models showed a better fit. Autoregressive effects were observed in sleep onset, sleep offset and sedentary behavior, which could explain the relationships found in previous studies between physical activity and sleep. Sleep onset, total sleep time, and sleep efficiency had direct effects on sedentary behavior. Moderate-to-vigorous physical activity was not related to any of the sleep variables.

Conclusions: The hypothesis that there are bidirectional/reciprocal relationships between physical activity and sleep cannot be accepted.

Background: Pre-exposure prophylaxis (PrEP) has been implemented as a prevention against HIV; however, its impact on mental health, sexual and life satisfaction has not been addressed.

Method: We assessed 114 HIV-negative participants from Spain with ages ranging from 19 to 58 years; 60.5% were PrEP users ( n = 69) and 39.5% were non-users ( n = 45). They completed five questionnaires about life and sexual satisfaction, depression and anxiety. We performed correlations and multiple regression analyses.

Results: The PrEP group showed a statistically significant relationship between better sexual satisfaction, and greater life satisfaction. The PrEP group also showed a statistically significant negative relationship with depression and anxiety which was not found in PrEP non-users. Moreover, we found that younger PrEP users had higher scores in anxiety and lower scores in depression than older users. The hierarchical regression analyses also showed that number of sexual partners was a major predictor in the PrEP group for NSSS.

Conclusions: The indirect correlation between sexual satisfaction, depression, and anxiety in the PrEP group could underly the benefits of PrEP for patients' sex lives such as increased sexual liberties due to lower anxiety and mental comfort when experiencing chemsex.

Background: Suicide is the second leading cause of death in young people aged 15-29 in Spain. It is imperative to detect cases with suicidal risk for early intervention. The purpose of the study was to examine the self-reported presence of suicide spectrum indicators using a trichotomous rating scale: no, yes, prefer not to say . This last alternative was intended to safeguard the sensitive nature of the phenomenon and explore its clinical character.

Method: 5,528 adolescents made up the definitive sample (12-18 years; M ± SD = 14.20 ± 1.53; 50.74% female).

Results: Prevalence reached 15.38% for ideation, 9.32% for planning, and 3.65% for previous suicide attempts. Girls' rates were twice those of men. Suicidality showed a tendency to increase with age. Adolescents with the presence of suicidal indicators (yes) and omission of response (prefer not to say) both had lower levels of socioemotional strength and subjective well-being, and higher levels of psychopathology than the group with the absence of markers (no).

Conclusions: Prefer not to say is a response category that increases the sensitivity of the self-report, allowing more accurate identification of cases with a high suicidal risk that would go unnoticed by the traditional dichotomous system (no-yes).

Background: The World Health Organization (WHO) developed an instrument to detect violence against women that has been widely used in several countries. Despite this instrument's importance in identifying intimate partner violence against women (IPVAW), it has not been adapted for the Spanish population. The aim of this study was to adapt and validate the WHO violence against women instrument in a sample in Spain, facilitating the detection of IPVAW in this context and comparisons between countries.

Method: After the instrument was translated and adapted into Spanish, 532 women from the general population in Spain completed it. The initial instrument consisted of 28 items. We deleted three items due to low internal consistency, resulting in 25 items in the final version.

Results: Suitable internal consistency was obtained through Confirmatory Factorial Analysis for physical (α = .92), psychological (α = .91), sexual (α = .86), and control behaviors subscales (α = .91) as well as for the total scale (α = .95). The instrument revealed highly prevalent IPVAW in our sample (79.7%).

Conclusions: The use of the Spanish version of the WHO violence against women instrument in Spain seems justified.

Background: Although several studies have reported an increase in psychological problems during the COVID-19 pandemic, the impact of stressful life events on Spanish children and adolescents using a person-oriented statistical approach and the relationships between the profiles and emotional and behavioral symptoms have not yet been examined. The present study aims to identify profiles of Spanish children and adolescents, considering life-threatening stressful events during the COVID-19 pandemic.

Method: Participants were 252 parents of children aged 3 to 15 years old who completed an online structured questionnaire that collected information about stressful life events related to the pandemic and its impact on their children's welfare.

Results: Through Latent Class Analysis (LCA), four profiles of children and adolescents were found according to the stressful events experienced: "COVID infection, social confinement", "economic loss", "reduced social contact" and "parental stress", with no significant age or gender differences. Reduction in social contact was the most prevalent stressor. Comparisons of psychological symptoms across latent classes were analyzed.

Conclusions: The findings increase our understanding of how stressful life events during the COVID-19 situation impacted young people's psychological welfare and highlight the need to promote strategies to prevent emotional problems during a pandemic considering the identified profiles.

Background: Suicidal behavior, especially in young populations such as university students, is currently one of the most concerning health problems worldwide, suicide being the second leading cause of death among students. Although literature is still scarce, one of the risk factors that correlates the most with suicidal behavior in young people appears to be problematic internet use (PIU). The aim of this study was to investigate the relationship between PIU and suicidal behavior in a Spanish university population.

Method: An ex post facto prospective design was used with a sample of 1,386 Spanish university students (68.7% women and 31.3% men). PIU was assessed by means of the Internet Addiction Test (IAT) and psychological problems by means of the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM).

Results: The results confirm the relationship between PIU and suicidal behavior, principally alongside those of social isolation and depression, this risk being 3.78 times higher among women with PIU and 5.58 times higher in men.

Conclusions: PIU appears as a risk factor for suicidal behavior that must be taken into account together with social isolation, subjective distress and depression.

Background: "Juego de Llaves" [ Set of Keys ] is a universal school-based prevention program for adolescents aged 12-15. It is aimed at reducing drug use and other addictive behaviors. This paper describes the full protocol for the evaluation design, instruments, randomization procedure, follow-ups, and primary outcomes.

Method: Non-Randomized Control Cluster Trial in a set of Spanish secondary schools, with follow-ups at 12-, 24- and 36-months. Participants will be allocated to an experimental or control group. Using a digital application designed for the study, a battery of instruments will be used to assess addictive behaviors, sociodemographic variables, school climate and other transdiagnostic psychological variables.

Results: A pilot test will be carried out to test the implementation protocol and to calculate the sample size needed for outcome evaluation. After implementing the program, longitudinal statistical approaches will be used to report intervention efficacy and potential moderators and mediators.

Conclusions: There is a lack of assessments on the effectiveness of school prevention programs, and this paper is expected to improve monitoring and ongoing evaluation in prevention.

Background: Using a foreign language can influence emotion modulation, but whether different psychotherapy processes would be affected by a foreign language is still unclear. The current study explored the foreign language effect on the extinction of fear.

Method: During the conditioning phase, part of the neutral stimuli presented to the participants were associated with a threat, while they performed a countdown task in their native language. In the extinction phase, participants performed the same task either in their native/foreign language and were informed that the threat would no longer appear. We collected self-reports of fear, and pupil dilation and electrodermal activity as physiological measures of arousal.

Results: Extinction was successful, indicated by greater self-reported fear and pupil dilation during the threat condition compared to neutral in the conditioning phase, but no significant differences during extinction. Although the foreign language group presented higher arousal, fear extinction occurred regardless of the linguistic context.

Conclusions: Fear extinction via verbal instructions is equally effective in a foreign and a native language context. These results indicate that evidence should be continue to be gathered on the role of foreign languages using basic paradigms with clinical applications.

Background: The emergence of digital technology in the field of psychological and educational measurement and assessment broadens the traditional concept of pencil and paper tests. New assessment models built on the proliferation of smartphones, social networks and software developments are opening up new horizons in the field.

Method: This study is divided into four sections, each discussing the benefits and limitations of a specific type of technology-based assessment: ambulatory assessment, social networks, gamification and forced-choice testing.

Results: The latest developments are clearly relevant in the field of psychological and educational measurement and assessment. Among other benefits, they bring greater ecological validity to the assessment process and eliminate the bias associated with retrospective assessment.

Conclusions: Some of these new approaches point to a multidisciplinary scenario with a tradition which has yet to be created. Psychometrics must secure a place in this new world by contributing sound expertise in the measurement of psychological variables. The challenges and debates facing the field of psychology as it incorporates these new approaches are also discussed.
