Compared with what? An analysis of control-group types in Cochrane and Campbell reviews of psychosocial treatment efficacy with substance use disorders.

Abstract: Background and Aims A crucial, but under-appreciated, aspect in experimental research on psychosocial treatments of substance use disorders concerns what kinds of control groups are used. This paper examines how the distinction between different control-group designs have been handled by the Cochrane and the Campbell Collaborations in their systematic reviews of psychosocial treatments of substance abuse disorders. Methods We assessed Cochrane and Campbell reviews (n = 8) that were devoted to psychosocial treatments of substance use disorders. We noted what control groups were considered and analysed the extent to which the reviews provided a rationale for chosen comparison conditions. We also analysed whether type of control group in the primary studies influenced how the reviews framed the effects discussed and whether this was related to conclusions drawn. Results The reviews covered studies involving widely different control conditions. Overall, little attention was paid to the use of different control groups (e.g. head-to-head comparisons versus untreated controls) and what this implies when interpreting effect sizes. Seven of eight reviews did not provide a rationale for the choice of comparison conditions. Conclusions Cochrane and Campbell reviews of the efficacy of psychosocial interventions with substance use disorders seem to underappreciate that the use of different control-group types yields different effect estimates. Most reviews have not distinguished between different control-group designs and therefore have provided a confused picture regarding absolute and relative treatment efficacy. A systematic approach to treating different control-group designs in research reviews is necessary for meaningful estimates of treatment efficacy.

Extensive internet involvement--addiction or emerging lifestyle?

Abstract: In the discussions for the future DSM-5, the Substance-Related Disorders Work Group has been addressing “addiction-like” behavioral disorders such as “Internet addiction” to possibly be considered as potential additions for the diagnostic system. Most research aiming to specify and define the concept of Internet addiction (or: Excessive/Compulsive/Problematic Internet Use—PIU), takes its point of departure in conventional terminology for addiction, based in established DSM indicators. Still, it is obvious that the divide between characteristics of addiction and dimensions of new lifestyles built on technological progress is problematic and far from unambiguous. Some of these research areas are developing from the neurobiological doctrine of addiction as not being tied to specific substances. The concept of “behavioral addictions”, based on biological mechanisms such as the reward systems of the brain, has been launched. The problems connected to this development are in this study discussed and reflected with data from a Swedish survey on Internet use (n = 1,147). Most Swedes (85%) do use the Internet to some degree. The prevalence of excessive use parallels other similar countries. Respondents in our study spend (mean value) 9.8 hours per week online at home, only 5 percent spend more than 30 hours per week. There are both positive and negative social effects at hand. Many respondents have more social contacts due to the use of Internet, but there is a decline in face-to-face contacts. About 40% of the respondents indicate some experience of at least one problem related to Internet use, but only 1.8% marked the presence of all problems addressed. Most significant predictors for problem indicators, except for age, relate to “time” and time consuming activities such as gaming, other activities online or computer skills.

The legitimacy of addiction treatment in a world of smart people

Abstract: Aim This paper discusses what type of legitimacy underpins addiction treatment in contemporary western societies. Method Broad review of the relevant literature. Conclusions The legitimacy of professional interventions and the future of service provision will depend largely on the relationship between the professional and the lay referral system. These in turn are intertwined with macro-societal changes. The basic categories in this relationship are, on one hand, the idea of evidence-based practice (i.e. the notion of using the most accurate scientific support for the choice of treatment interventions), and on the other hand the consumer perspective, which conceptualizes addiction treatment as an interactive process between the treatment provider and the consumer. The acceptance of addiction treatment depends in most cases on the client who chooses from a whole range of informal and formal problem solutions. To an extent, experts are thus controlled by their lay counterparts and need their consent to operate and succeed. This process is complicated by the trend towards evidence-based practice, which demands transparency and rigorous procedures and carries with it the basis for distrust in expert knowledge by displaying openly that every statement of fact is open to revision, and thus, to a certain extent, characterized by uncertainty.

Guided or independent? Social workers, central bureaucracy and evidence-based practice

Abstract: Since the start of the 1990s, a number of professional fields in the Western world have been confronted with increasingly explicit demands for scientific assurance regarding the effects of the work they do. The debate on the relationship between research and practice in social work has often been carried out under the heading of evidence-based social work or evidence-based practice (EBP). This article is based on a survey distributed to a representative sample of social workers and middle managers within the Swedish municipal social services. The results indicate a generally positive attitude among Swedish social workers towards EBP; at the same time they show a low level of active contact with the research literature of relevance for EBP. The results are contextualized and discussed against the background of some major methodological issues in EBP, such as, for example, the so called Dodo bird verdict in psychotherapy outcome research.

Why most published research findings are false

Abstract: There is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true when the studies conducted in a field are smaller; when effect sizes are smaller; when there is a greater number and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance. Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true. Moreover, for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias. In this essay, I discuss the implications of these problems for the conduct and interpretation of research.

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.

Diagnostic And Statistical Manual Of Mental Disorders 4th Edition

Abstract: Drug addiction is a pathological state; the disorder involves the progression of acute drug use to the development of drug seeking behavior. The diagnostic and statistical manual of mental disorders, 4th edition, categorized three stages of drug addictions preoccupation, anticipation, binge intoxication and withdrawal or negative effect. These stages are characterized respectively by constant craving and preoccupation with obtaining the substance, using more of the substance and experience the necessary intoxicating effects and experiencing tolerance withdrawal symptoms and decrease motivation of normal life activities.

Over the 15 year period the emphasis in catalogued material has been predominantly on youth, women, and racial and ethnic groups. The increase in abstracted materials for all the special populations in the last five years deserves notice; youth and women are the categories for which the most materials are recorded. There is also a marked increase in attention paid to college students, whereas there seems to be a slight tapering off in attention paid to elderly, youth, and American Indians. It is possible to characterize the literature abstracted in the NCADI data base as containing only a very few controlled trials in which the effectiveness of generic treatment is compared with treatment specifically tailored to the characteristics of the special population under consideration. There is a paucity of adequate studies on treatment outcome for any of the groups identified (Gilbert and Cervantes, 1988; Vannicelli, 1988; Westermeyer, 1988). The comment on treatment outcome made by Braiker (1982) continues to have current general applicability to all special population groups: A review of the general literature on alcoholism treatment effectiveness reveals that most studies either fail to distinguish between outcome rates for men and women alcoholics or exclude the latter group from the study samples altogether. Among those studies that distinguish outcome rate by sex, varying and often conflicting results are reported. (p. 127) Whereas the NCADI data base offers with insight into the research and and clinical practice emphasis on special populations, data from the National Drug and Alcohol Treatment Survey (NDATUS) can help to identify both the trends and the current distribution of treatment programs available for special population groups. These were surveys of alcoholism treatment services provided by all known public and private alcoholism and drug abuse facilities and units in the United States (NIAAA, 1983; Reed and Sanchez, 1986; NIDA/NIAAA 1989) (see Chapter 4 and Chapter 7). Table 14-2 presents data on the number of specialized programs offered by alcoholism treatment units by the year THE TREATMENT OF SPECIAL POPULATIONS: OVERVIEW AND DEFINITIONS 351 Broadening the Base of Treatment for Alcohol Problems Copyright National Academy of Sciences.

Youth, women, the elderly, Hispanics, public inebriates, and blacks were the only special population groups included in all three of these surveys; American Indians/Alaskan natives were included in the last two surveys.

The inventory asked respondents to identify whether they offered one or more specialized programs to certain population groups. Judging on the basis of the treatment units reporting, it appears that an increasing percentage of units are offering one or more specialized programs. In 1987 the largest number of specialized programs offered in treatment units were for youth (31 percent), followed closely by those for women (28 percent), with a sharp drop to programs for Hispanics (11 percent) and the elderly (8 percent). Changes in the total number of units reporting and in the number of specialized programs must be interpreted cautiously because there was a more thorough outreach effort in 1984 to locate all units that were either not identified in 1982 or that did not respond; this effort may simply have uncovered existing units that had not responded earlier rather than identifying new units that had only recently been established (cf. Reed and Sanchez, 1986:2). An examination of these two sources—the NCADI database and the NIAAA surveys of treatment units— shows that women and youth are the special population groups that have received the most attention since the early 1970s. What they do not reveal are the most effective ways to meet the needs of individual problem drinkers or how to identify factors germane to a special population that might affect treatment. The overviews are also unable to provide guidance on when treatment should emphasize an individual's special population membership to facilitate a successful outcome. Indeed, if these overviews tell us anything, it is that women and youth appear to be the special population groups that people are most concerned about. Given the historical dilemmas, variations, and inconsistencies in defining which groups should be considered as special populations in the planning, funding and evaluation THE TREATMENT OF SPECIAL POPULATIONS: OVERVIEW AND DEFINITIONS 352 Broadening the Base of Treatment for Alcohol Problems Copyright National Academy of Sciences. All rights reserved. of alcohol problems treatment, Lex (1985:90) has suggested that a special population be defined as any subgroup that is “special in terms of their uniformity on some dimension and their differences from more typical societal patterns and problems.” The committee agrees with this definition. However, the definition does not fully capture the problems encountered in attempting to review existing knowledge on the value of special population programming. This review of the history of attention to special population groups suggests that their definition is often not only in terms of the unique biological and sociocultural characteristics that define a group with similar risk factors and drinking practices but also in terms of the momentary concern regarding access to appropriate services. Interest in each group has waxed and waned. There has been no systematic follow up to determine whether access has been improved or treatment outcome positively affected by these periods of attention. What is challenging, for both researchers and clinicians, is to determine where and how the emphasis on special population membership can best facilitate effective treatment for alcohol problems. Given this background, for the purposes of this report, a special population will be viewed as any subgroup that has been identified by the field as needing a specifically tailored “culturally sensitive” treatment program. The committee has chosen to look at developments and issues for only a few of the commonly identified special population groups and the evolution and effectiveness of treatment programs designed for them as portrayed in the research and clinical literature. It is important to note that these groups are by no means inclusive of all special population groups; rather, they have been selected as representatives of special populations as a whole. Chapter 15 considers these groups on the basis of structural characteristics (i.e., demographic characteristics); Chapter 16, adapts the perspectives of functional characteristics (i.e., circumstantial concerns) as a definitional framework. Chapter 17 presents the committee's conclusions and recommendations on the issue of treatment for alcohol problems among special populations.
