Longitudinal and Reciprocal Relations of Cyberbullying With Depression, Substance Use, and Problematic Internet Use Among Adolescents

Abstract: Purpose: To analyze the temporal and reciprocal relationships between being a victim of cyberbullying (CB) and three frequent problems during adolescence: depressive symptoms, substance use, and problematic Internet use; also, to analyze whether the relationship between CB and these psychological and behavioral health problems differs as a function of being only a victim or being both bully and victim. Method: A total of 845 adolescents (mean age ¼ 15.2, SD ¼ 1.2) completed measures at T1 and at T2, 6 months apart. The relationship among variables was analyzed using structural equation modeling. Results: CB victimization at T1 predicted depressive symptoms and problematic Internet use at T2, and higher depressive symptoms and more substance use at T1 predicted more CB victimization at T2. However, the relationships of CB predicting substance use and problematic Internet use predicting CB were not significant. Bully-victims presented higher levels than victims of all three problem variables, both at T1 and T2. Conclusions: CB is predictive of some significant psychological and behavioral health problems among adolescents. Intervention efforts should pay attention to these in the prevention and treatment of consequences of CB.

The development and validation of the cyber dating abuse questionnaire among young couples

Abstract: Development and validation of Cyber Dating Abuse Questionnaire.Two factors: direct aggression (greater than 70% prevelence) and control (higher than 10% prevelence).Cyber dating abuse has relationship with offline dating violence and cyberbullying. Cyber dating abuse is a growing phenomenon that has awakened little empirical interest. This study had two objectives: (1) to analyze the psychometric properties of the Cyber Dating Abuse Questionnaire (CDAQ), which is an instrument developed to comprehensively measure this phenomenon; and (2) to conduct an initial analysis of the prevalence and frequency of this type of abuse. The sample consisted of 788 young people between 18 and 30years of age (77.3% women, mean age=22.72years, SD=4.9). First, exploratory and confirmatory factor analyzes revealed a structure composed of two factors for the scales of victimization and for perpetration: direct aggression (an aggressive act with a deliberate intention to hurt the partner/ex-partner, such as insults or threats) and monitoring/control (the use of electronic means to control the partner/ex-partner; for example, the use of personal passwords). Second, the analysis of the relationship between cyber dating abuse and other variables, such as offline physical and psychological violence and cyberbullying, provided additional evidence for the construct validity of the instrument. Third, the reliability analysis (Cronbach's alpha) revealed an adequate internal consistency for the scale. Finally, the prevalence of direct aggression was higher than 10%, and the prevalence of control was greater than 70%, which indicate that both types of cyber abuse seem to be common behaviors among young couples. Finally, the contribution of the present study to previous empirical research and future research is discussed.

Prevalence and Association of Sexting and Online Sexual Victimization Among Spanish Adults

Abstract: This study has two objectives: (1) to investigate the occurrence of sexting and online sexual victimization (OSV) in adults by sex, age, and sexual orientation and 2) to analyze whether participating in sexting is a risk factor for OSV. The sample included 873 Spanish 18- to 60-year-old adults. Approximately two thirds of the adults had been involved in sexting, and one in three had experienced OSV. In general, no differences were found in sexting between men and women; however, sexting was more common among young adults and non-heterosexuals. In contrast, OSV was more common in women, young and middle-aged adults, and non-heterosexuals. Finally, sexting increased the probability of reporting OSV after controlling for the effects of sex, age, and sexual orientation. The relationship between sexting and OSV was stronger when the sexual content was sent to a person met online only compared to sexting with a partner or with friends or acquaintances. These findings are discussed in light of the implications for practice and future research.

Depressive symptoms and problematic internet use among adolescents: analysis of the longitudinal relationships from the cognitive-behavioral model

Abstract: Problematic Internet use-frequently called Internet addiction or compulsive use-represents an increasingly widespread problem among adolescents. The objective of this study was to analyze the temporal and reciprocal relations between the presence of depressive symptoms and various components of problematic Internet use (i.e., the preference for online relationships, use of the Internet for mood regulation, deficient self-regulation, and the manifestation of negative outcomes). Consequently, a longitudinal design was employed with two times separated by a 1 year interval. The sample consisted of 699 adolescents (61.1% girls) between 13 and 17 years of age. The results indicated that depressive symptoms at time 1 predicted an increase in preference for online relationships, mood regulation, and negative outcomes after 1 year. In turn, negative outcomes at time 1 predicted an increase in depressive symptoms at time 2. These results entail several practical implications for the design of prevention programs and the treatment of problematic Internet use.

Cyber dating abuse: prevalence, context, and relationship with offline dating aggression.

Abstract: The use of information and communication technologies (ICT) as tools to intimidate, harass, and control the partner has been, so far, little studied in the literature. The aim of this study was to determine the extension and sex differences of victimization of cyber dating abuse, as well as the context in which it occurs, and its relationship with offline psychological and physical aggressions. The sample consisted of 433 college students ages 18 to 30 years. The results showed that over 50% of the participants had been victims of some type of cyber dating abuse in the last six months. The most common behavior was the use of ICT to control the partner. Also, victims of cyber dating abuse were victimized repeatedly, an average of 23 times in the last six months. The data also showed that cyber dating abuse appear usually in a context of jealousy. Finally, the results revealed a significant relationship between cyber dating abuse and offline psychological dating aggressions. Limitations and future lines of research are discussed.

Internet addiction: a systematic review of epidemiological research for the last decade.

Abstract: In the last decade, Internet usage has grown tremendously on a global scale. The increasing popularity and frequency of Internet use has led to an increasing number of reports highlighting the potential negative consequences of overuse. Over the last decade, research into Internet addiction has proliferated. This paper reviews the existing 68 epidemiological studies of Internet addiction that (i) contain quantitative empirical data, (ii) have been published after 2000, (iii) include an analysis relating to Internet addiction, (iv) include a minimum of 1000 participants, and (v) provide a full-text article published in English using the database Web of Science. Assessment tools and conceptualisations, prevalence, and associated factors in adolescents and adults are scrutinised. The results reveal the following. First, no gold standard of Internet addiction classification exists as 21 different assessment instruments have been identified. They adopt official criteria for substance use disorders or pathological gambling, no or few criteria relevant for an addiction diagnosis, time spent online, or resulting problems. Second, reported prevalence rates differ as a consequence of different assessment tools and cut-offs, ranging from 0.8% in Italy to 26.7% in Hong Kong. Third, Internet addiction is associated with a number of sociodemographic, Internet use, and psychosocial factors, as well as comorbid symptoms and disorder in adolescents and adults. The results indicate that a number of core symptoms (i.e., compulsive use, negative outcomes and salience) appear relevant for diagnosis, which assimilates Internet addiction and other addictive disorders and also differentiates them, implying a conceptualisation as syndrome with similar etiology and components, but different expressions of addictions. Limitations include the exclusion of studies with smaller sample sizes and studies focusing on specific online behaviours. Conclusively, there is a need for nosological precision so that ultimately those in need can be helped by translating the scientific evidence established in the context of Internet addiction into actual clinical practice.

Depression and anxiety.

Abstract: Depression and anxiety are the most common psychiatric conditions in late life. Despite their prevalence, we know relatively little about their unique manifestation in older adults. And, Although the most common intervention for late-life depression and anxiety continues to be medication, research on psychosocial interventions for late-life depression and anxiety has burgeoned in the past several years. Unfortunately, this growing body of intervention research has yet to be widely translated into improved systems of care for late-life depression. This article is one step toward synthesizing the knowledge in this growing area of research. The review of literature presents the conclusions of several meta-analyses that have reviewed psychosocial interventions for late-life depression and anxiety. In addition, intervention studies concerning the effectiveness of cognitive behavioral therapy, interpersonal therapy, reminiscence therapy, and alternative therapies with depressed and/or anxious older adults are reviewed. A brief description of various approaches to psychosocial intervention with anxious and/or depressed older adults is also presented.

Associations of parenting dimensions and styles with externalizing problems of children and adolescents: An updated meta-analysis.

Abstract: The present meta-analysis integrates research from 1,435 studies on associations of parenting dimensions and styles with externalizing symptoms in children and adolescents. Parental warmth, behavioral control, autonomy granting, and an authoritative parenting style showed very small to small negative concurrent and longitudinal associations with externalizing problems. In contrast, harsh control, psychological control, authoritarian, permissive, and neglectful parenting were associated with higher levels of externalizing problems. The strongest associations were observed for harsh control and psychological control. Parental warmth, behavioral control, harsh control, psychological control, autonomy granting, authoritative, and permissive parenting predicted change in externalizing problems over time, with associations of externalizing problems with warmth, behavioral control, harsh control, psychological control, and authoritative parenting being bidirectional. Moderating effects of sampling, child's age, form of externalizing problems, rater of parenting and externalizing problems, quality of measures, and publication status were identified. Implications for future research and practice are discussed. (PsycINFO Database Record
