OBJECTIVES: We aimed to measure the prevalence and length of the problem of pathological video gaming or Internet use, to identify risk and protective factors, to determine whether pathological gaming is a primary or secondary problem, and to identify outcomes for individuals who become or stop being pathological gamers. METHODS: A 2-year, longitudinal, panel study was performed with a general elementary and secondary school population in Singapore, including 3034 children in grades 3 (N = 743), 4 (N = 711), 7 (N = 916), and 8 (N = 664). Several hypothesized risk and protective factors for developing or overcoming pathological gaming were measured, including weekly amount of game play, impulsivity, social competence, depression, social phobia, anxiety, and school performance. RESULTS: The prevalence of pathological gaming was similar to that in other countries (∼9%). Greater amounts of gaming, lower social competence, and greater impulsivity seemed to act as risk factors for becoming pathological gamers, whereas depression, anxiety, social phobias, and lower school performance seemed to act as outcomes of pathological gaming. CONCLUSION: This study adds important information to the discussion about whether video game “addiction” is similar to other addictive behaviors, demonstrating that it can last for years and is not solely a symptom of comorbid disorders.

Preliminary research studies suggest that some people who use computer, video games, and the Internet heavily develop dysfunctional symptoms, often referred to in the popular press as an “addiction.” Although several studies have measured various facets of this issue, there has been no common framework within which to view these studies. This paper aims to provide a conceptual framework of “impulse control disorders” and describe what is known currently based on a review of the international literature, and highlight what remains to be studied. We suggest the term “Pathological Technology Use” (PTU) rather than “internet addiction”, since there is robust construct validity (via convergent validity and comorbidity) for pathological computer, video game and Internet use, regardless of how individual researchers defined or measured it. Questions concerning diagnostic criteria are raised, and a common set of diagnostic criteria is proposed.

Family Therapy in the Forbidden City: A Review of Chinese Journals From 1978 to 2006

Timothy Sim; Chiyi Hu

This article provides a glimpse into the development of family therapy in China, by reviewing family therapy articles written in Chinese and published in journals in China that are not, therefore, readily accessible to the international community. A content analysis of journals published between 1978 and 2006 revealed 199 family therapy articles in 109 Chinese journals. Most of the studies were conducted by psychiatry or medical professionals, and were based on general systems theory or a systemic family therapy model. The articles focused on the promotion of family therapy theories and interventions in China, but did not specify the application of theory to specific clientele or symptoms. After the year 2000, a threefold increase in the number of family therapy publications was noted. These papers included the introduction of additional theories, but did not include critical assessment of the applicability of Western family therapy models to Chinese families. The researchers noted an absence of articles that identified Chinese approaches to family therapy, and a paucity of papers on gender, professional reflection, and the therapy process. The article concludes that there is room for improvement in the quality of family therapy publications in China, and that gains may be made by interdisciplinary collaboration among academics and practitioners.

Pathological video-gaming among youth: A prospective study examining dynamic protective factors

Albert K. Liau; Hyekyung Choo; Dongdong Li; Douglas A. Gentile; Timothy Sim; Angeline Khoo

Abstract The primary aim of the study was to understand the phenomenon of pathological video-gaming by identifying protective factors for its development, and examining the dynamic interplay between protective factors and pathological video-gaming within a framework of change. The study was a 2-year longitudinal study involving 3034 children and adolescents recruited from 6 elementary and 6 secondary schools. Controlling for initial levels of pathological video-gaming, personal strengths and familial factors such as parent–child connectedness, and warm family environment were found to be protective factors for later pathological gaming. Increases in levels of emotional regulation and family environment warmth were related to decreases in pathological video-gaming. Higher initial levels and increases in pathological video-gaming were related to higher levels of later depressive symptoms, controlling for earlier levels of depressive symptoms. The study adds to the growing evidence that pathological video-gaming has potentially serious mental health consequences, in particular, on depression. For health providers who work with pathological video-gamers, the findings suggest that developing self-regulatory skills such as emotional regulation, and improving the family environment are useful strategies.

Family therapists from 10 different countries (China, India, Israel including Palestinian citizens, Japan, Mexico, Peru, Spain, Turkey, Uganda, and the United Kingdom) describe systemic therapy in their contexts and current innovative work and challenges. They highlight the importance of family therapy continuing to cut across disciplines, the power of systems ideas in widely diverse settings and institutions (such as courts, HIV projects, working with people forced into exile), extensive new mental health initiatives (such as in Turkey and India), as well as the range of family therapy journals available (four alone in Spain). Many family therapy groups are collaborating across organizations (especially in Asia) and the article presents other ideas for connections such as a clearing house to inexpensively translate family therapy articles into other languages.

Given the potential negative mental health consequences of pathological video gaming, understanding its etiology may lead to useful treatment developments. The purpose of the study was to examine the influence of impulsive and regulatory processes on pathological video gaming. Study 1 involved 2154 students from 6 primary and 4 secondary schools in Singapore. Study 2 involved 191 students from 2 secondary schools. The results of study 1 and study 2 supported the hypothesis that self-regulation is a mediator between impulsivity and pathological video gaming. Specifically, higher levels of impulsivity was related to lower levels of self-regulation, which in turn was related to higher levels of pathological video gaming. The use of impulsivity and self-regulation in predicting pathological video gaming supports the dual-system model of incorporating both impulsive and reflective systems in the prediction of self-control outcomes. The study highlights the development of self-regulatory resources as a possible avenue for future prevention and treatment research.

The New York statement on the evolving definition of practice research designed for continuing dialogue: a bulletin from the 3rd International Conference on Practice Research (2014)

Irwin Epstein; Mike Fisher; Ilse Julkunen; Lars Uggerhøj; Michael J. Austin; Timothy Sim

This Statement on Practice Research is a work in progress. It emerges out of deliberations from three international conferences on defining and operationalizing practice research. It seeks to capture both a process and outcome in which practitioners, researchers, service users, and educators collectively engage in a negotiated process of inquiry. One of the goals of this form of research is to place equal emphasis on improving practice and improving services. Practice research also seeks to rebalance the power relations in terms of integrating the voices of service users, service providers, service researchers, and instructors preparing future and current service providers. This third statement emerges out of the most recent international conference in New York City (2012) and continues the construction of the social science and social philosophy foundation of practice research. It seeks to expand the dialogue on practice research to include more international voices while also searching for linkages with the evolving process of defining the mixed methods approach to evidence-informed practice. This Statement provides a platform for the 4th International Conference on Practice Research planned for Hong Kong in 2017.

Black cat, white cat: a pragmatic and collaborative approach to evidence‐based social work in China

Timothy Sim; Guat Tin Ng

Current thinking suggests that evidence‐based practice (EBP) is a key to unlocking the potential for social work development in mainland China. But Chinese social workers may be confronted by the challenges of EBP in using research evidence, exercising expert judgment, as well as considering client characteristics, as social work is a relatively new enterprise in Chinas unique social–economic–political context. There is little indigenous research evidence for Chinese social workers to refer to. There are few experienced social workers and researchers since social work practice, education and research were reinstated only in the late 1980s. Mainland Chinese may not be aware of what social workers can do and may prefer authority‐based practice. This paper aims to first review the definition of EBP, followed by a discussion of the challenges and opportunities in applying EBP to social work in China. It then highlights the usefulness of collaboration between academics, practitioners, and clients in implementing EBP. A recent research project on ex‐offenders and their family members in Singapore is used to illustrate the feasibility of collaboration between academia and the field. 当前的理论认为, 以证据为本的实践是一个解开中国大陆社会工作重新发展潜能的钥匙。 然而, 中国社会工作者在运用研究证据、行使专业判断及考虑服务使用者的特质时, 或许会遇到实证为本的挑战, 因为在中国独特的社会、经济及政治环境下, 社会工作是一个相对地新兴的专业, 没有太多本土化的研究证据可供中国社会工作者参考。 同时, 因为社会工作实践、教育及研究在1980年代末期才得以复苏, 也没有太多富有经验的社会工作者及研究人员。 中国内地民众或许未曾意识到社会工作者能够做什么, 宁可依据以权威为本的实践。 本文的主要目的首先是检视以证据为本的实践的定义, 然后讨论在中国应用以证据为本的实践的挑战及机遇。 文章突出了在引用以证据为本的实践时, 学术界、前线工作者及服务使用者相互合作的益处。 藉一项在新加坡进行的前刑事犯人及其家人的近期研究成果, 以说明学术界与社会工作界合作的可行性。

Rising to the occasion: Disaster social work in China

Timothy Sim; Angelina Yuen-Tsang Woon Ki; Chen Hui Quen; Qi Hua Dong

The fifth year since the deadly Wenchuan earthquake that killed more than 87,000 people will be commemorated in 2013. This article critically reviews the development and charts the direction of disaster social work in China, since the fateful 2008 Wenchuan earthquake jump-started it dramatically. While disaster social work publications, social work projects and organizations surged, young Chinese social workers felt challenged by poor professional recognition, harsh working conditions and limited prospects and support. However, they have been spurred onwards by the resilience and growth of their clients and professional fulfilment in the daunting process of recovery and reconstruction.

An Integrated Method Combining Remote Sensing Data and Local Knowledge for the Large-Scale Estimation of Seismic Loss Risks to Buildings in the Context of Rapid Socioeconomic Growth: A Case Study in Tangshan, China

Guiwu Su; Wenhua Qi; Suling Zhang; Timothy Sim; Xinsheng Liu; Rui Sun; Lei Sun; Yifan Jin

Rapid socioeconomic development in earthquake-prone areas can cause rapid changes in seismic loss risks. These changes make it difficult to ensure that risk reduction strategies are realistic, practical and effective over time. To overcome this difficulty, ongoing changes in risk should be captured timely, definitively, and accurately and then specific and well-timed adjustments of the relevant strategies should be made. However, methods for rapidly characterizing such seismic disaster risks over a large area have not been sufficiently developed. By focusing on building loss risks, this paper presents the development of an integrated method that combines remote sensing data and local knowledge to resolve this problem. This method includes two key interdependent steps. (1) To extract the heights and footprint areas of a large number of buildings accurately and quickly from single high-resolution optical remote sensing images; (2) To estimate the floor areas, identify structural types, develop damage probability matrixes, and determine economic parameters for calculating monetary losses due to seismic damage to the buildings by reviewing building-relevant local knowledge based on these two parameters (i.e., the building heights and footprint areas). This method is demonstrated in the Tangshan area of China. Based on the integrated method, the total floor area of the residential and public office buildings in central Tangshan in 2009 was 3.99% lower than the corresponding area number obtained by a conventional earthquake loss estimation project. Our field-based verification indicated that the mean relative error of the method for estimating the floor areas of the assessed buildings was 2.99%. A simulation of the impacts of the 1976 Ms 7.8 Tangshan earthquake using this method indicated that the total damaged floor area of the residential and public office buildings and the associated direct monetary loses in the study area could have been 8.00 and 28.73 times greater, respectively, than in 1976 if this earthquake had recurred in 2009, which is a strong warning to the local people regarding the increasing challenges they may face.
