Variables associated with the nature of sexual abuse to minors

This study analyzes the prevalence and characteristics of childhood and adolescence sexual abuse suffered by a sample of university students, as well as the variables associated with the nature of abuse. Participants anonymously completed the Questionnaire on Child Sexual Abuse, in order to obtain information about experience of sexual abuse. Of a total of 2,375 students, 289 (12.2%) declared having suffered sexual abuse before the age of 18. The invasiveness, continuity, and severity of abuse was related to the location where the abuse took place (the more severe cases were committed in the homes of the victim and perpetrator) and to the circumstances of abuse (relationships with partners/at a party or while caring for a child predicted more severe abuse). The age of the victim (preschool) and an intrafamilial relationship between victim and perpetrator were also related to more invasive, continuous, and severe sexual abuse. The knowledge of characteristics of perpetrator and victim and the context in which sexual abuse occurs can help to better comprehend the nature and correlates of sexual abuse. The results of the present study may contribute to the design of programs for the prevention of sexual abuse to minors.     

Morningness-eveningness and health-related quality of life among adolescents

Accumulating evidence suggests that evening-type adolescents are exposed to a number of determinants that might have a negative impact on their health condition. Given that few studies have investigated the association between chronotype and quality of life measures in large samples of adolescents, the aim of this study was to assess the relationship between morningness-eveningness and health-related quality of life among 1600 adolescents (aged 12-16 years). Adolescents completed the Ve?u et Santé Per?ue de L'adolescent (VSP-A) and the Morningness-Eveningness Scale for Children (MESC). Girls and older adolescents reported worse health indicators and were more evening oriented. Evening-type adolescents obtained lower scores on vitality, physical and psychological well-being, body image, relations with parents, relations with teachers, school work and global health scale.     

Screening utility of the social anxiety screening scale in Spanish speaking adolescents

The aim of this study was to analyse the screening utility of the Social Anxiety Screening Scale (SASS/EDAS) in a sample of 227 adolescents with social anxiety disorder and 156 Without it (14-17 years). Results showed that the EDAS subscales (Avoidance, Distress and Interference) scores were reliable in terms of internal consistency (alpha > .80). All the subscales discriminated between adolescents with and without the disorder. They also showed a positive and significant correlation with other empirically validated measures of social anxiety. The three subscales indicated relevant sensitivity (69.16-84.14%), specificity (63.46-66.03%) and areas under the curve (.74-.81%). Binary logistic regression analyses indicated the adequate predictive utility of EDAS subscales, with the Distress subscale as the best diagnostic predictor. The data provide empirical evidence of the usefulness of EDAS as a screener for adolescent social anxiety disorder in terms of reliability, convergent and discriminant validity, diagnostic accuracy and clinical usefulness.     

The memory failures of everyday questionnaire (MFE): internal consistency and reliability

The Memory Failures of Everyday Questionnaire (MFE) is one of the most widely-used instruments to assess memory failures in daily life. The original scale has nine response options, making it difficult to apply; we created a three-point scale (0-1-2) with response choices that make it easier to administer. We examined the two versions' equivalence in a sample of 193 participants between 19 and 64 years of age. The test-retest reliability and internal consistency of the version we propose were also computed in a sample of 113 people. Several indicators attest to the two forms' equivalence: the correlation between the items' means (r = .94; p < .001) and the order of the items' frequencies (r = .92; p < .001). However, the correlation between global scores on the two forms was not very high (r = .67; p < .001). The results indicate this new version has adequate reliability and internal consistency (r(xx) = .83; p < .001; alpha = .83; p < .001) equivalent to those of the MFE 1-9. The MFE 0-2 provides a brief, simple evaluation, so we recommend it for use in clinical practice as well as research.     

Box for interaction with objects (BIO): A new device to synchronize the presentation of objects with electrophysiological recordings

Brain event-related potentials are a useful tool for investigating visual processing and action planning. This technique requires extremely accurate synchronization of stimulus delivery with recordings. The precision of the onset time of visual stimulus delivery is a major challenge when attempting to use real, three-dimensional objects as stimuli. Here, we present an innovative device, the “box for interaction with objects” (BIO), that is designed to synchronize the presentation of objects with electroencephalographic (EEG) recordings. To reach the required resolution of stimulus-onset timing, the BIO system features an interface with reflective glass and light-emitting diodes (LEDs). When the LEDs inside the BIO are turned on, the object inside becomes visible, and a synchronizing pulse is sent to the recording systems. The BIO was tested in a motivational study that focused on visual and motor event-related potentials. EEG signals were recorded during the presentation of an emotion-laden object that could be grasped and brought close to the participant’s chest. BIO successfully synchronized the appearance of a three-dimensional object with EEG recordings, which would allow for an analysis of visual and motor event-related potentials in the same experiment. The BIO device, through a high-quality psychophysiological approach, offers a new perspective for the study of the motivational factors that drive actions toward relevant stimuli.     

Comparison between immigrant and Spanish native-born pathological gambling patients

The study compared clinical, psychopathological, and personality profiles between immigrants and Spanish native-born pathological gambling patients. A total of 1,601 native-born and 133 immigrant patients attending treatment at a specialized hospital unit were administered a battery of questionnaires during clinical assessment. Outcome measures were compared between both groups and the incremental predictive accuracy of the area of origin was examined using a regression model. Native-born Spaniards showed a mean 2.6 yr. greater duration of the disorder, while immigrants scored higher on South Oaks Gambling Screen, frequency of going to casinos, and total money spent (in a single day and/or to recover losses). General psychopathology and personality scores did not differ between the cohorts. However, immigration from Asia had a statistically significantly incremental validity for pathological gambling in South Oaks Gambling Screen scores. Both cohorts shared more similarities than differences in their gambling profiles.     

Bitter reproach or sweet revenge: cultural differences in response to racism

Culture has been shown to influence response styles. The authors conducted two studies to test the notion that African Americans would be more likely to respond to racism directly, whereas Asian Americans would be more likely to respond indirectly and therefore more subtly. Study 1 showed that Black women subjected to a racist comment from a confederate during an online interaction were more likely than Asian women to verbally reproach the perpetrator. These group differences were not present when the outcome measure was indirect responding--administration of good/bad jellybeans. Study 2 used an online format to demonstrate that Asian women were more likely than Black women to say they would not respond directly to a racist comment. This group difference in unwillingness to confront was significantly mediated by a goal of maintaining peace with their interaction partner. Implications of these findings for the study of discrimination, coping, and well-being are discussed.     

Sexual behavior in Spanish adolescents of divorced parents

Marital breakup has been associated with numerous behavioral problems in children, such as sexual risk behaviors. This research is the first to examine sexual behaviors of Spanish adolescents related to whether their parents were married or divorced. Participants were 342 boys and girls aged between 14 and 18 years. The sample provided confidential information about their sexual behavior and birth control methods. Significant differences were only found in percentages of adolescents who had engaged in mutual masturbation, intercourse, or oral sex, and who had practiced these sexual relations in the last six months, in both cases, they were higher when the parents had broken their marital relationship. Regarding adolescents of divorced parents, engaging in intercourse is more likely in older teenagers who live with a stepparent. Moreover, older adolescents who were younger when parents divorced and who live in a reconstituted family, have more sexual partners. These and other findings are discussed.     

Influence of perceived social support and functioning on the quality of life of patients with schizophrenia and their caregivers

Perception of social support and functioning of patients with schizophrenia and their primary caregivers and its relationship to quality of life are described. Forty-five patients and their 45 relatives, treated at the Mental Health Services in Arica, Chile, participated. Both patients and caregivers in the study have a poor perception of social support with regard to extra-family people, as well as a low social integration. However, patients showed adequate capacity to function within their immediate family. Unlike what was found in developed countries, these patients showed moderate levels of quality of life, with a strong relationship with perceptions of the social support they receive from family and significant others and the ability to establish and maintain social contacts. Quality of life of primary caregivers is linked to patients' ability to establish and maintain social contacts within the family group, as in other social instances, such as keeping a job. The results of the study suggest the need to consider the design and application of programs of support for these patients and their caregivers, with the central aim of the social functioning of the above-mentioned patients and their familiar and community integration.     

Methods for averaging alpha coefficients in reliability generalization studies

The reliability generalization (RG) approach is a kind of meta-analysis that aims to statistically integrate a set of independent reliability coefficients obtained in several applications of a test, with the purpose of characterizing the measurement error and determining which factors related to the studies and samples can explain its variability. Diverse procedures have been proposed in the literature for averaging a set of independent alpha coefficients, and there is no consensus about which methods are best. Here, we present the results of a Monte Carlo simulation study, comparing the performance of twelve procedures proposed in Feldt and Charter, in terms of bias and mean square error. These procedures differ from each other in the transformation (or not) of the coefficients, and in the application or not of a weighting scheme based on sample size. Our results recommend using weighted methods in contrast to unweighted ones, and transforming the coefficients by the Hakstian and Whalen's proposal or by the proposal based on the square root of the inverse alpha coefficient. Lastly, we discuss the relations between the diverse procedures for averaging alpha coefficients with fixed-effects, random-effects, and varying coefficients models.
