Predictors of problematic smartphone use among university students

Abstract Predictors of problematic smartphone use have been found mainly in studies on elementary and high school students. Few studies have focused on predictors related to social network and messaging apps or smartphone model. Thus, the objective of our study was to identify predictors of problematic smartphone use related to demographic characteristics, loneliness, social app use, and smartphone model among university students. This cross-sectional study involved 257 Brazilian university students who answered a smartphone addiction scale, a questionnaire about smartphone usage patterns, and the Brazilian version of the UCLA-R loneliness scale. Women, iPhone owners, and users of Instagram and Snapchat had significantly higher smartphone addiction scores. We found correlations between scores for the Brazilian version of smartphone addiction scale and the importance attributed to WhatsApp, Facebook, Instagram, and Snapchat, and the Brazilian version of the UCLA-R loneliness scale. Our hierarchical regression model predicted 32.2% of the scores of the Brazilian version of the smartphone addiction scale, with the greatest increase in predictive capability by the step that added smartphone social app importance, followed by the step that added loneliness. Adding the smartphone model produced the smallest increase in predictive capability. The theoretical and practical implications of these results are discussed.

Smartphone and Facebook addictions share common risk and prognostic factors in a sample of undergraduate students / Dependência de smartphone e dependência de Facebook compartilham fatores de risco e prognósticos em uma amostra de estudantes universitários

Abstract Introduction To improve the comprehension of the interface between smartphone addiction (SA) and Facebook addiction (FA), we hypothesize that the occurrence of both technological addictions correlate, with higher levels of negative consequences. Moreover, we hypothesize that SA is associated with lower levels of social support satisfaction. Methods We recruited a convenience sample of undergraduate students from Universidade Federal de Minas Gerais, with age ranging between 18 and 35 years. All subjects completed a self-fulfilled questionnaire comprising sociodemographic data, the Brazilian Smartphone Addiction Inventory (SPAI-BR), the Bergen Scale for Facebook Addiction, the Barrat Impulsivity Scale 11 (BIS-11), the Social Support Satisfaction Scale (SSSS), and the Brief Sensation Seeking Scale (BSSS-8). After completing the questionnaire, the interviewer conducted a Mini-International Neuropsychiatric Interview (MINI). Results In the univariate analysis, SA associated with female gender, with ages 18 to 25 years, FA, substance abuse disorders, major depressive disorder, anxiety disorders, low scores in SSSS, high scores in BSSS-8, and high scores in BIS. The group with SA and FA presented a higher prevalence of substance abuse disorders, depression, and anxiety disorders when compared to the group with SA only. Conclusion In our sample, co-occurrence of SA and FA correlated with higher levels of negative consequences and lower levels of social support satisfaction. These results strongly suggest that SA and FA share some elements of vulnerability. Further studies are warranted to clarify the directions of these associations.

Resumo Introdução Para melhorar a compreensão da interface entre dependência de smartphone (DS) e a dependência de Facebook (DF), avaliamos a hipótese de que a ocorrência simultânea de ambas as dependências corelaciona-se com o número de consequências negativas por elas produzidas. Além disso, avaliamos se a DS está associada a níveis mais baixos de satisfação com o suporte social. Método Recrutamos uma amostra de conveniência de estudantes de graduação da Universidade Federal de Minas Gerais, na faixa de 18 e 35 anos. Todos os sujeitos preencheram o questionário avaliando dados sociodemográficos e contendo a versão brasileira do Smartphone Addiction Inventory, a Escala de Bergen para DF, a Escala de Impulsividade de Barrat 11 (BIS-11), a Escala de Satisfação com o Suporte Social (SSSS) e a Escala Breve de Busca de Sensações (BSSS-8). Após o preenchimento do questionário, os entrevistadores realizaram a Mini-International Neuropsychiatric Interview. Resultados Na análise univariada, a DS associou-se ao sexo feminino, pessoas na faixa de idade entre 18 e 25 anos, rastreio para DF, transtornos por uso de substâncias, transtorno depressivo maior, transtornos de ansiedade, baixos escores na SSSS, altos escores na BSSS-8 e altos escores na BIS. O grupo rastreado positivamente para DS e DF apresentou maior prevalência de transtornos por uso de substâncias, depressão e transtornos de ansiedade quando comparado ao grupo rastreado apenas para DS. Conclusão Na amostra avaliada, a comorbidade de DS e DF se correlacionou a níveis mais altos de consequências negativas e níveis mais baixos de satisfação com o suporte social. Esses resultados sugerem que DS e DF compartilham fatores de vulnerabilidade. Estudos adicionais são necessários para esclarecer a direção dessas associações.

Associations of parental bonding and adolescent internet addiction symptoms with depression and anxiety in parents of adolescents with attention deficit/hyperactivity disorder

Abstract Objectives The aim of the present study was to evaluate the associations of parental bonding and adolescents' Internet addiction symptoms with depression and anxiety in parents of adolescents with attention deficit/hyperactivity disorder (ADHD). Methods Parental depression and anxiety symptoms, parental bonding, and adolescents' Internet addiction symptoms were assessed in 46 parent-child dyads using the Center for Epidemiological Studies Depression Scale, State-Trait Anxiety Inventory, Parental Bonding Instrument (PBI), and Chen Internet Addiction Scale, respectively. Forward stepwise multiple regression analysis was used to examine the associations of parental bonding and adolescents' Internet addiction symptoms with parental depression and anxiety. Results Low care/affection on the PBI was significantly associated with parental depression, and overprotection on the PBI and adolescents' Internet addiction were significantly associated with parental anxiety. Discussion Parental bonding and adolescents' Internet addiction are related to depression and anxiety in parents of adolescents with ADHD.

An exploration of addiction in adults experiencing early-life stress: a metasynthesis / Uma investigação sobre o vício em adultos com estresse no início da vida: uma metassíntese / Una exploración de la adicción en adultos que han sufrido estrés durante los primeros años de su vida: una metasíntesis

ABSTRACT Objective: to review and synthesize qualitative research on the links between early-life stress and addiction behaviours in adulthood. Method: metasynthesis to review qualitative research findings based on procedures that outline how to identify themes or constructs across studies in a specific area. Comprehensive searches of multiple electronic databases were performed. The initial search yielded 1050 articles and the titles and abstracts were screened for inclusion based on predetermined criteria. Thirty-eight full text, peer-reviewed articles were retrieved and assessed by three independent reviewers. Twelve articles were eligible for full review and appraised using the Critical Appraisal Skills Programme (CASP) tools. Results: the findings revealed that clear associations exist between early-life stress and addictive behaviours in adulthood, such as between trauma in childhood, violence, and addictive behaviours. A common theme in the findings indicates that participants turn to addictive substances as a way of strategically coping with stressful childhood experiences, regardless of the harmful side effects or detrimental social outcomes. Conclusion: it can be inferred that addiction may be viewed as a way to deal with adversity in childhood and that there is an interrelationship between addiction, domestic violence and crime.

RESUMO Objetivo: revisar e sintetizar pesquisas qualitativas sobre os vínculos entre o estresse no início da vida e os comportamentos de dependência na idade adulta. Método: metassíntese para revisar resultados de pesquisa qualitativa com base em procedimentos que descrevem como identificar temas ou construtos através de estudos em uma área específica. Foram realizadas pesquisas abrangentes em múltiplas bases de dados eletrônicas. A pesquisa inicial produziu 1.050 artigos, cujos títulos e resumos foram selecionados para inclusão com base em critérios predeterminados. Trinta e oito textos completos de artigos revisados por pares foram recuperados e avaliados por três revisores independentes. Doze artigos foram elegíveis para revisão completa e avaliados usando as ferramentas do Programa de Competências de Avaliação Crítica (Critical Appraisal Skills Programme, CASP). Resultados: os achados revelaram que existem associações claras entre o estresse no início da vida e comportamentos aditivos na idade adulta, como entre trauma na infância, violência e comportamentos aditivos. Um tema comum nas descobertas indica que os participantes se voltam para substâncias aditivas como uma maneira de lidar estrategicamente com experiências estressantes da infância, independentemente dos efeitos colaterais deletérios ou resultados sociais prejudiciais. Conclusão: pode-se inferir que o vício pode ser visto como uma forma de lidar com a adversidade na infância e que existe uma inter-relação entre vício, violência doméstica e crime.

RESUMEN Objetivo: revisar y sintetizar la investigación cualitativa referida a la relación entre el estrés durante la infancia y las conductas adictivas en la adultez. Método: metasíntesis que examina los resultados de investigaciones cualitativas basadas en procedimientos orientados a identificar temas o constructos en diferentes estudios en un área específica. Se realizaron búsquedas exhaustivas en múltiples bases de datos electrónicas. La búsqueda inicial arrojó 1.050 artículos. Sus títulos y resúmenes fueron analizados para determinar si debían incluirse en este estudio en base a criterios predeterminados. Se obtuvieron treinta y ocho artículos completos revisados por expertos que fueron evaluados por tres revisores independientes. Entre ellos, doce fueron seleccionados para una revisión detallada y evaluados mediante las herramientas del Programa de Habilidades de Evaluación Crítica (CASP por sus siglas en inglés). Resultados: los resultados revelaron que existe una asociación clara entre el estrés de la infancia y las conductas adictivas en la edad adulta, al igual que entre los traumas infantiles, la violencia y las conductas adictivas. Un aspecto común encontrado en los resultados es que los participantes recurren a las sustancias adictivas como una estrategia para lidiar con experiencias estresantes de su niñez, independientemente de sus efectos secundarios dañinos o de sus resultados sociales perjudiciales. Conclusión: se concluye que la adicción puede ser vista como una forma de lidiar con la adversidad en la niñez y que existe una interrelación entre la adicción, la violencia doméstica y la delincuencia.

Concomitant stress potentiates the preference for, and consumption of, ethanol induced by chronic pre-exposure to ethanol

Ethanol abuse is linked to several acute and chronic injuries that can lead to health problems. Ethanol addiction is one of the most severe diseases linked to the abuse of this drug. Symptoms of ethanol addiction include compulsive substance intake and withdrawal syndrome. Stress exposure has an important role in addictive behavior for many drugs of abuse (including ethanol), but the consequences of stress and ethanol in the organism when these factors are concomitant results in a complex interaction. We investigated the effects of concomitant, chronic administration of ethanol and stress exposure on the withdrawal and consumption of, as well as the preference for, ethanol in mice. Male Swiss mice (30-35 g, 8-10 per group) were exposed to an ethanol liquid diet as the only source of food for 15 days. In the final 5 days, they were exposed to forced swimming stress. Twelve hours after removal of the ethanol liquid diet, animals were evaluated for ethanol withdrawal by measuring anxiety-related behaviors and locomotor activity. Twenty-four hours after evaluation of ethanol withdrawal, they were evaluated for voluntary consumption of ethanol in a "three-bottle choice" paradigm. Mice exposed to chronic consumption of ethanol had decreased locomotor activity during withdrawal. Contrary to our expectations, a concomitant forced swimming stress did not aggravate ethanol withdrawal. Nevertheless, simultaneous ethanol administration and stress exposure increased voluntary consumption of ethanol, mainly solutions containing high concentrations of ethanol. These results showed that stressful situations during ethanol intake may aggravate specific addiction-related behaviors.

Craving e dependência química: conceito, avaliação e tratamento / Craving and chemical dependence: concept, evaluation and treatment

O craving ou fissura, cuja definição mais comum é o desejo intenso por uma substância, é um conceito controverso entre os pesquisadores da área da dependência química. OBJETIVO: Realizar revisão teórica a respeito do craving nos bancos de dados PsycInfo, Medline, ProQuest e Science Direct. MÉTODO: As palavras-chave utilizadas foram craving, dependence e drug e o período pesquisado foi entre 1995 e 2007. RESULTADOS: Os resultados demonstraram que são encontrados diversos significados para o craving, alguns se restringindo a desejo, e outros, considerando-o não só como desejo, mas como antecipação do resultado positivo do uso da substância, alívio dos sintomas de abstinência ou afeto negativo e intenção de fumar, o que reflete uma visão multidimensional deste construto. A etiologia do craving pode ser explicada por intermédio dos modelos: comportamental, cognitivo ou psicossocial e neurobiológico, porquanto a opção por um destes influencia a avaliação e o manejo. CONCLUSÃO: Conclui-se quanto à multidimensionalidade do craving e quanto à necessidade de que seja utilizado um modelo biopsicossocial que integre os diversos modelos no tratamento de dependentes químicos. Destaca-se a importância da realização de mais estudos para a compreensão do craving em função deste ser um dos principais riscos de recaída.

Craving is usually defined as an intense desire for a substance. This is a rather controversial concept among the researchers on the chemical dependence area. OBJECTIVE: The objective of this study was to carry out a theoretical review concerning craving at PsycInfo, Medline, ProQuest, Portal Capes and Science Direct Data Bases. METHODS: The keywords used were craving, dependence and drug, and the searching period was between 1995 and 2007. RESULTS: The results showed that many different meanings can be found for craving, some relate it only to desire, while others consider it not only as desire, but also as the anticipation of the positive result from the use of the substance, the relief of abstinence symptoms or negative affect and intention to smoke, which reflects a multidimensional view of this construct. The ethimology of craving can be explained by the following Models: Behavioral, Cognitive or Psychosocial and Neurobiological, being the option for one of them a factor that influences evaluation and usage. CONCLUSION: As a conclusion, we are in favor of craving multidimensionality, as well as the need to use a Biopsychsocial Model that integrates the various models for treating chemical dependent patients. It is also necessary to highlight the importance of carrying out more studies in oder to understand craving, for it is one of the principal risks of relapse.

Perfil del farmacodependiente a heroína en una cárcel del Estado de Baja California Norte (México) / Heroin drug-addict profile among jail in-mates in Baja California

Con la mira de conocer al farmacodependiente a heroína, y sus variables sociodemográficas, se revisaron 150 expedientes de un penal y se practicó una entrevista estructurada entre mayo de 1996 y enero de 1997.
