Item response theory analysis of diagnostic criteria for alcohol and cannabis use disorders in adolescents: implications for DSM-V

Item response theory (IRT) has advantages over classical test theory in evaluating diagnostic criteria. In this study, the authors used IRT to characterize the psychometric properties of Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV; American Psychiatric Association, 1994) alcohol and cannabis use disorder symptoms among 472 clinical adolescents. For both substances, DSM-IV symptoms fit a model specifying a unidimensional latent trait of problem severity. Threshold (severity) parameters did not distinguish abuse and dependence symptoms. Abuse symptoms of legal problems and hazardous use, and dependence symptoms of tolerance, unsuccessful attempts to quit, and physical-psychological problems, showed relatively poor discrimination of problem severity. There were gender differences in thresholds for hazardous use, legal problems, and physical-psychological problems. The results illustrate limitations of DSM-IV criteria for alcohol and cannabis use disorders when applied to adolescents. The development process for the fifth edition (DSM-V) should be informed by statistical models such as those used in this study.     

Mentorship behaviors and mentorship quality associated with formal mentoring programs: closing the gap between research and practice

Formal mentoring programs continue to gain popularity within organizations despite limited empirical research regarding how these programs should be designed to achieve maximum effectiveness. The present study examined perceived design features of formal mentoring programs and outcomes from both mentor and protégé perspectives. The outcomes examined were career and psychosocial mentoring, role modeling, and mentorship quality. In general, the results indicated that perceived input into the mentoring process and training perceived as high in quality were consistently related to the outcome variables. Implications for the design of formal mentoring programs and future theory development are discussed.     

Standard posture,postural mirroring and client-perceived rapport

The relationship between client-perceived rapport (as measured from a standardized client) and physical mirroring and the standard counsellor posture was investigated with interviews performed by 59 post-graduate students in counselling psychology. Videotaped recordings were used to code counsellor posture in the categories of: total postural mirroring, mirroring of the hands and arms, mirroring of the legs, mirroring of the torso, and the frequency of the standard counsellor posture across each minute of the interviews. These minutes were classified as 'high' in rapport or 'low' in rapport as measured by the standardized client. Results indicated that there was significantly more postural mirroring of the torso during high versus low minutes, but that the counsellor standard posture occurred significantly more frequently during low rapport minutes than in high rapport minutes. However, when examined over the entire length of the interviews, these data were able to be understood in terms of counsellor 'flexibility' of response rather than simply whether these postural behaviours were present or not. Implications for counsellor training are discussed.     

Initial Development and Validation of the Multidimensional Students’ Life Satisfaction Scale–Adolescent Version

The factor structure of a new self-report scale, the Multidimensional Students’ Life Satisfaction Scale–Adolescent version, was examined. Reliability and 2-week stability estimates of the domain scores and total score were calculated. Relationships of the domain and total scores with other well-being measures were examined as well as the impact of social desirability responding. Although additional development is necessary, results provided preliminary psychometric support for the MSLSS–A for research purposes.The usefulness of life satisfaction measures vis-à-vis the positive psychology movement (Seligman and Csikzentmihalyi, American Psychologist, 55(1): 5-14, 2000) is highlighted.     

When flexibility helps: Another look at the availability of flexible work arrangements and work-family conflict

Despite the positive press given to flexible work arrangements (FWA), empirical research investigating the link between the availability of these policies and work-family conflict is largely equivocal. The purpose of the present study was to begin to reconcile these mixed results through more precise measurement and the examination of moderators. Using a sample of employed women, we found that FWA relate more highly to work interference with family (WIF) than to family interference with work (FIW) and that temporal flexibility (flextime) has a stronger relationship with WIF than does spatial flexibility (flexplace). Additionally, we found family responsibility significantly moderated these relationships, such that the relationship was stronger for those with greater family responsibility. Practical and theoretical implications are discussed.     

Validation of the multiple language versions of the Hopkins Symptom Checklist-37 for refugee adolescents

The objective of this study is to provide preliminary psychometric properties of the Hopkins Symptom Checklist-37 (HSCL-37A) for refugee adolescents. The HSCL-37A is a modification of the well-known HSCL-25 and assesses symptoms of internalizing and externalizing problems that have been associated with reactions to trauma. Four independent heterogeneous samples (N=3890) of unaccompanied refugee minors, immigrants, and native Dutch and Belgian adolescents were assessed at school. The confirmative factor analyses, per language version, support the two-factor structure of internalizing and externalizing behavior. The total and subscales show good internal consistency and acceptable test-retest reliability in spite of the heterogeneous sample populations. The construct, content, and criterion validity of the HSCL-37A were also examined and found to be good. The findings of this study suggest that the HSCL-37A is a reliable and valid instrument to be used among culturally diverse refugee adolescents to assess emotional distress and maladaptive behaviors.     

LABELING OF ABUSE EXPERIENCES AND RATES OF VICTIMIZATION

Research has consistently found that a history of previous sexual victimization increases risk for future sexual assault, which might be due to women with a history of sexual victimization having difficulty identifying risky cues and not perceiving their own vulnerability for future assaults. This study investigated how acknowledgment of previous experiences with interpersonal violence is related to risk perception and rates of victimization. Participants were 198 college women who completed assessments of victimization, personal risk appraisal, and acknowledgment. Analyses indicated differences in rates of victimization based on labeling of experiences and differences in efforts to change behaviors to reduce risk for future assaults based on level of acknowledgment. Also, there were a number of situational factors significantly related to likelihood of acknowledgment. The findings differed for physical and sexual violence. This study suggests that acknowledgment is an important factor to consider in studies of sexual and physical revictimization.
