“…In contrast, the agglomeration coefficients and dendrogram generated from the Ward's algorithm clearly indicated that a three-group solution accounted for clustering in the data. C l u s t e r A n a l y t i c S t u d y These conflicting results are generally consistent with research on cluster analysis techniques (e.g., Morey, Blashfield, & Skinner, 1983;Wells-Parker, Anderson, Pang, & Timken, 1993). When there are relatively few outliers (as in these data) and cluster overlap (i.e., groups occupying the same space) is judged to be a greater consideration, Ward's method has been shown to outperform other clustering procedures (Aldenderfer & Blashfield, 1984).…”

Three distinct clinical orientations were identified in a sample of chemical dependency counselors (N = 406). Based on cluster analysis, the largest group, identified and labeled as "uniform counselors," endorsed a simple, moral-disease model with little interest in psychosocial interventions. A 2nd group, identified as "multiform counselors," embraced an incongruent moral-diseasepsychosocial model, and valued a myriad of treatment approaches. The smallest group, labeled "client-directed counselors," did not fully endorse Alcoholics Anonymous (AA) principles, valued non-coercive treatment, and recognized coexisting psychopathology in clients. Results from a discriminant function analysis provided evidence to support the 3-group cluster solution.Electronic Journal: To print this article select pages 66-74. TOC

“…Considering that each study had not used the same set of clustering variables, some variations were expected to be found either in the number of clusters or in the main shared characteristics within one subgroup (Wells-Parker et al, 1993). However, when using similar concepts to form clusters, some types of grouping were indeed repetitively found.…”

“…Before discussing specific differences and similarities of each cluster compared to previous literature, some overall points should to be considered to explain some global divergences. Considering that each study had not used the same set of clustering variables, some variations were expected to be found either in the number of clusters or in the main shared characteristics within one subgroup (Wells‐Parker et al., 1993). However, when using similar concepts to form clusters, some types of grouping were indeed repetitively found.…”

Young adults that drive after cannabis use (DACU) may not share all the same characteristics. This study aimed to identify typologies of Canadians who engage in DACU. About 910 cannabis users with a driver's license (17-35 years old) who have engaged in DACU completed an online questionnaire. Two-step cluster analysis identified four subgroups, based on driving-related behaviors, cannabis use and related problems, and psychological distress. Complementary comparative analysis among the identified subgroups was performed as external validation. The identified subgroups were: (1) frequent cannabis users who regularly DACU; (2) individuals with generalized deviance with diverse risky road behaviors and high levels of psychological distress; (3) alcohol and drug-impaired drivers who were also heavy frequent drinkers; and (4) well-adjusted youths with mild depressive-anxious symptoms. Individuals who engaged in DACU were not a homogenous group. When required, prevention and treatment need to be tailored according to the different profiles.

“…The stability of the classification procedures was evaluated by using the procedures described by Wells-Parker, Anderson, Pang, and Timken (1993). Calibration equations, using discriminant analysis, were generated from the first sample and applied to the second sample to predict group membership.…”

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) Validity scales (L, F, and K) were used to identify subgroups of inpatients seeking treatment for alcoholism and to determine the extent that assessed test-taking attitude could be generalized to other alcohol assessment instruments. Cluster analysis of the inpatients receiving treatment for alcoholism identified 3 distinct response style subgroups: defensive, straightforward, and exaggerated. These patterns were confirmed in a 2nd sample. Calibration equations were generated and used to classify a subsequent sample into subgroups, and expected differences were found across the subgroups on the Alcohol Use Inventory (J. L. Horn, K. W. Wanberg, & F. M. Foster, 1987) and the Inventory of Drinking Situations (H. M. Annis, 1982). These preliminary results suggest that MMPI-2 response style is associated with response to other alcohol abuse assessment instruments. Future research examining the relationship between test-taking attitude and treatment involvement and outcome is discussed. Meehl and Hathaway (1946) were among the first researchers to suggest that personality inventories were susceptible to both conscious "faking" and unconscious self-deception. In their landmark Minnesota Multiphasic Personality Inventory (MMPI; Meehl & Hathaway, 1946) work, they devised the Lie (L) and Correction (K) scales (Meiydith & Wallbrown, 1991) to assess response bias. The L scale assesses overall frankness in the individual's approach to the instrument. High L scores are indicative of an unsophisticated attempt to present oneself in a favorable light. The K scale assesses a more subtle attempt to respond defensively and is indicative of an attempt to deny problems and demonstrate no need for psychologi-
