ABSTRACT The concurrent, construct and discriminative validity of the World Health Organization's Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) were examined in a multi-site international study.
One thousand and 47 participants, recruited from drug treatment (n = 350) and primary health care (PHC) settings (n = 697), were administered a battery of instruments.
Measures included the ASSIST; the Addiction Severity Index-Lite (ASI-Lite); the Severity of Dependence Scale (SDS); the MINI International Neuropsychiatric Interview (MINI-Plus); the Rating of Injection Site Condition (RISC); the Drug Abuse Screening Test (DAST); the Alcohol Use Disorders Identification Test (AUDIT); the Revised Fagerstrom Tolerance Questionnaire (RTQ); and the Maudsley Addiction Profile (MAP).
Concurrent validity was demonstrated by significant correlations between ASSIST scores and scores from the ASI-Lite (r = 0.76-0.88), SDS (r = 0.59), AUDIT (r = 0.82) and RTQ (r = 0.78); and significantly greater ASSIST scores for those with MINI-Plus diagnoses of abuse or dependence (P < 0.001). Construct validity was established by significant correlations between ASSIST scores and measures of risk factors for the development of drug and alcohol problems (r = 0.48-0.76). Discriminative validity was established by the capacity of the ASSIST to discriminate between substance use, abuse and dependence. Receiver operating characteristic (ROC) analysis was used to establish cut-off scores with suitable specificities (50-96%) and sensitivities (54-97%) for most substances.
The findings demonstrated that the ASSIST is a valid screening test for identifying psychoactive substance use in individuals who use a number of substances and have varying degrees of substance use.

    • "The Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) is a self-report instrument that assesses past and current substance use, problems related to use, potential future risk, and dependence (Henry-Edwards et al. 2003). Internal consistency coefficients range from Cronbach's α of 0.77 for the hallucinogens scale to 0.94 for the opioids and amphetamines scales (Humeniuk et al. 2008). "

    ABSTRACT: Clinically relevant identity disturbance, rather than more normative identity confusion, is a construct that has received limited empirical attention. This relative lack of empirical research is surprising, given that identity disturbance is a criterion for BPD, among the proposed features of all DSM-5 personality disorders, and may also be relevant for many other psychiatric diagnoses. The nomenclature used to describe identity-related constructs is currently unstandardized and many theorists have described overlapping concepts. Thus, there is a need to operationalize identity problems and improve measurement of this important construct. In this article we report the results of two studies that establish the psychometric properties and factor structure of the Self- Concept and Identity Measure (SCIM). The SCIM is a brief, self-report scale designed to assess dimensions of identity (healthy and disturbed) among adults. Participants were recruited through a psychology department subject pool (Study 1; n=536) and also through Amazon’s Mechanical Turk Website (Study 2; n=470). An exploratory factor analysis of Study 1 data revealed a 3-factor structure. A confirmatory factor analysis validated the 3-factor structure in the community sample recruited for Study 2. Results indicate that the SCIM is correlated with emotion dysregulation, Borderline Personality Disorder, depression, and other measures of psychopathology. Scores on the SCIM yielded high internal consistency (Cronbach’s α=0.89), test–retest reliability (α=0.93, r=0.88; intraclass correlation coefficient=0.88), and adequate construct validity. The SCIM appears to produce valid and reliable test scores, with promising applications for clinical research and practice.

    ABSTRACT: This study describes the development of the Game Addiction Inventory for Adults (GAIA). First, a pool of 147 video game addiction-related items was generated from interviews with 25 people who have had experience with video game addiction and a literature review. Next, an online survey of 456 adult-aged video game players drawn from university students and participants of online video game web sites provided data for reduction of the item pool and examination of the factor structure of the pool using common factor analysis. Finally, a correlational analysis was conducted between the factor solution and associated variables. The GAIA consists of five addiction-related subscales: loss of control and consequences, agitated withdrawal, coping, mournful withdrawal, and shame; and a 26-item overall addiction subscale was produced by summing these five factors. In addition, an engagement subscale was also developed from the factor analytic process and was found to be quantitatively and qualitatively different from the addiction related subscales. The subscales of the GAIA demonstrated good internal consistency, good convergent validity, and concurrent validity with other measures of video game addiction. The GAIA demonstrated mixed discriminant validity with pathological gambling and substance addictions. Future research should continue to investigate the psychometric properties of the GAIA and the utility of its subscales in research and clinical settings.

    • "-item screening instrument was used to help determine eligibility for study participation, along with stratification information, which included gender, year of university, and frequency of marijuana use in the past 90-days. The marijuana frequency question was from the NIDA-modified version of the Alcohol, Smoking, and Substance Involvement Test (ASSIST) (Humeniuk et al., 2008; NIDA, 2009). "

    ABSTRACT: This pilot study sought to test the feasibility of procedures to screen students for marijuana use in Student Health Services (SHS) and test the efficacy of a web-based intervention designed to reduce marijuana use and consequences. Students were asked to participate in voluntary screening of health behaviors upon arrival at SHS. One hundred and twenty-three students who used marijuana at least monthly completed assessments and were randomized to one of four intervention conditions in a 2 (intervention: Marijuana eCHECKUP TO GO vs. control)×2 (site of intervention: on-site vs. off-site) between-groups design. Follow-up assessments were conducted online at 3 and 6months. Latent growth modeling was used to provide effect size estimates for the influence of intervention on outcomes. One thousand and eighty undergraduate students completed screening. The intervention did not influence marijuana use frequency. However, there was evidence of a small overall intervention effect on marijuana-related consequences and a medium effect in stratified analyses in the on-site condition. Analyses of psychological variables showed that the intervention significantly reduced perceived norms regarding peer marijuana use. These findings demonstrate that it is feasible to identify marijuana users in SHS and deliver an automated web-based intervention to these students in different contexts. Effect size estimates suggest that the intervention has some promise as a means of correcting misperceptions of marijuana use norms and reducing marijuana-related consequences. Future work should test the efficacy of this intervention in a full scale randomized controlled trial.
