Continuity and change in personality traits from adolescence to midlife: a 25-year longitudinal study comparing representative and adjudicated men

In the first study, a hierarchical structure of personality traits was identified using data from a longitudinal study tracing two samples of men from adolescence to midlife (i.e., a representative sample of the general population and a sample of individuals adjudicated during their adolescence). The second study examined structural, rank-order, and mean-level continuity. Partial structural continuity was demonstrated through confirmatory factor analysis. Regarding rank-order continuity, the correlations were stronger as age increased, particularly for the adjudicated men. For mean-level continuity, the adjudicated men displayed higher scores from adolescence to midlife for nearly every personality trait related to Disinhibition and Negative Emotionality. Significant decreases were observed in these traits for both samples, supporting the hypothesis of a normative psychological maturation. Although both samples showed this maturation, the adjudicated men displayed a lower rate of change during adolescence and early adulthood. The two samples did not differ in Extraversion and this trait remained more stable, particularly for adjudicated men.     

Predictors of Teens' Attitudes Toward Condoms: Gender Differences in the Effects of Norms

Using data collected from a telephone survey of adolescents aged 15 to 19, we studied predictors of condom attitudes. Analyses were conducted on a sample of 348 sexually active teens. Multiple regression revealed that holding other variables constant being females, African American, perceiving that more of their friends were using condoms (i. e., perceived normative behavior). and stronger perceived normative pressure were significantly associated with favorable condom attitudes. Furthermore, significant interaction effects pointed to gender differences in the association between two types of norms and attitudes toward condoms. Perceived normative behavior had a greater effect on the attitudes of female adolescents. Perceived normative pressure had a greater effect on the attitudes of male adolescents.     

Type A Personality,Self-Control,and Vulnerability to Stress

The Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A; Butcher et al., 1992) was released in 1992 and has rapidly become the most widely used objective personality assessment instrument with adolescents. Although the MMPI-A reduced or eliminated several problems associated with the use of the original MMPI (Hathaway &; McKinley, 1943) with adolescents, the MMPI-A does produce a high frequency of within normal limits basic scale profiles for individuals with substantial psychopathology including adolescents in inpatient psychiatric settings. To better understand the reasons for this phenomenon, we compared the item endorsement frequencies for the MMPI-A normative sample with results from two adolescent clinical samples, and these results were contrasted to the item endorsement frequencies for the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, &; Kaemmer, 1989) normative sample and a clinical sample of adult psychiatric inpatients. Results showed that the MMPI-A contains a substantial number of items that do not show a significant difference in item endorsement frequency between normative and clinical samples. Furthermore, MMPI-A basic and content scales generally show a much lower percentage of effective items than do the corresponding scales for the MMPI-2. We discuss the findings in relation to the frequent occurrence of low range MMPI-A profiles in clinical samples and the potential usefulness of these results in future efforts to develop viable short forms for the MMPI-A.     

The effectiveness of MMPI-A items in discriminating between normative and clinical samples.

Gender differences in smoking: A longitudinal study of beliefs predicting smoking in 11–15 year olds

This longitudinal study investigated differences in beliefs and perceived behavioural control between smokers and non-smokers in a large sample of adolescents. Positive and negative instrumental beliefs, normative beliefs, perceived behavioural control (PBC) and smoking status were assessed in the same participants at 11, 13 and 15 years of age. Prospective analyses among non-smokers revealed that for boys, negative instrumental beliefs in non-smokers at age 11 predicted smoking at age 15 years. For girls, normative beliefs and PBC in non-smokers at age 11 predicted smoking status at age 13; normative beliefs at age 11 predicted smoking at age 15; and positive instrumental beliefs and normative beliefs at age 13 predicted smoking status at age 15. Cross-sectional data revealed that smokers were significantly more likely than non-smokers to endorse positive instrumental beliefs, less likely to agree with negative instrumental belief items, more likely than non-smokers to perceive social pressure to smoke, and less likely to report control over smoking, and that female smokers reported less control over smoking and fewer negative instrumental beliefs than all other groups including male smokers at age 13. The need for belief-based preventative interventions that are age- and gender-relevant is discussed.     

MAPI-C: The Jury Is Still Out (Software)

This article examines one aspect of the potential usefulness of critical items to the: Minnesota Multiphasic Personality Inventory -Adolescent (MMPI-A). Endorsement frequency data are presented on the Koss-Butcher (1973) and the Lachar-Wrobeli (1979) critical items for Minnesota Multiphasic Personality Inventory-2 (MMPI-2) adult normative and clinical samples and for MMPI-A adolescent normative and clinical samples. Adolescents in both normal and clinical samples endorse critical items with a higher frequency than do normal adults. Further, results demonstrated that significant differences were uniformly found between the endorsement frequencies for normative versus clinical subjects for the MMPI-2 samples, whereas similar comparisons for the MMPI-A samples typically showed that adolescents in clinical setting did not endorse critical items more frequently than normal adolescents. These findings indicate that it may be difficult to construct critical item lists for adolescents based on the type of empirical methodology used with adults in which items are selected based on endorsement frequency differences found between comparison group. Beyond the issue of the technical difficulty in creating a critical item list for adolescents, several conceptual concerns are raised regarding the application of critical items to the MMPI-A. It was noted that the concept of "critical items" has not been we11 defined, and both the reliability and validity of critical items may be limited in adolescent populations.     

Vocational Preference Inventory High Point Codes and Educational Preferences

This study reports normative data describing the combinations of various VPI high point codes associated with educational preferences classified into one of six of Holland's occupational environments and an undecided category. Eight hundred thirty-one male and 129 female college freshmen were queried regarding their educational preferences and were administered the VPI directly prior to college enrollment. The comparisons between preferences and VPI combinations revealed that Intellectual and Realistic, Social and Enterprising, Conventional and Enterprising, and Social and Artistic, seem to go together frequently for male students. The female sample revealed that Social and Artistic VPI codes were common.     

Are critical items "critical" for the MMPI-A

This article examines one aspect of the potential usefulness of critical items to the: Minnesota Multiphasic Personality Inventory -Adolescent (MMPI-A). Endorsement frequency data are presented on the Koss-Butcher (1973) and the Lachar-Wrobeli (1979) critical items for Minnesota Multiphasic Personality Inventory-2 (MMPI-2) adult normative and clinical samples and for MMPI-A adolescent normative and clinical samples. Adolescents in both normal and clinical samples endorse critical items with a higher frequency than do normal adults.

Changes in adolescent response patterns on the MMPI/MMPI--a across four decades

The purpose of this study was to explore changes in adolescent self-presentation on the Minnesota Multiphasic Personality Inventory (MMPI; Hathaway & McKinley, 1940) and MMPI-A (Butcher et al., 1992) over a 40-year period. The primary samples used for comparison in this study include 1,235 adolescents, age 14 through 16, derived from the MMPI-A normative sample (Butcher et al., 1992) collected in 1989 and 10,514 adolescents, age 14 through 16, collected in 1948 and 1954 from Hathaway and Monachesi's (1963) study of adolescent personality and behavior. MMPI basic scale and item-level data were also included for 817 adolescents, age 14 through 16, collected by Colligan and Offord (1992) in 1985 as a further comparison. Between-sample analyses at the profile level revealed that adolescents from the MMPI-A normative sample scored significantly higher across basic clinical scales and lower on validity scales L and K than adolescents from the Hathaway and Monachesi (1963) sample, with mean data from the Colligan and Offord (1992) sample typically falling at a midpoint value. Analyses of Harris-Lingoes (Harris & Lingoes, 1955) subscale and item-level data were conducted to provide refined definitions of the contents of scale-level changes. Results were interpreted as reflecting moderate to large changes in response frequencies between eras of data collection, and emphasis was placed on the relatively high frequency of item endorsements by contemporary adolescents in the clinical direction in the MMPI-A normative sample. A series of cautions and limitations are also offered in interpreting these patterns.     

Assessing differences in chemically dependent adolescent males using the Child Behavior Checklist

A study was conducted with 59 chemically dependent (CD) male adolescents (ages 13 to 16) using the Child Behavior Checklist (CBC). The CD sample was compared to a normative group on four adaptive behavior scales and twelve behavior problem scales, and was found to be significantly different on all measures. The CD sample was also compared to a general clinical group on nine behavior problem scales, and was found to score significantly higher on scales measuring delinquent and uncommunicative behaviors, and significantly lower on scales measuring immature and hostile-withdrawn behaviors. Summary profile types were compared with the clinical population and a separate assaultive/aggressive population. More of the CD population fit an uncommunicative/delinquent profile type and relatively fewer fit schizoid and immature/aggressive profile types as compared to the two other groups. The CBC differentiated subgroups in the CD sample with respect to completion of treatment and type of drug used, but not motivation for treatment at admission.     

Non-Suicidal Self-Injury Among Male Adjudicated Adolescents: Psychosocial Concerns,Coping Responses,Diagnoses, and Functions

Non-suicidal self-injury (NSSI) refers to self-inflicted physical injury without suicidal intent. NSSI is particularly common in forensic settings and associated with several psychosocial concerns, coping responses, diagnoses, and functions, but little information is available regarding NSSI in adjudicated male adolescents. The present study examined the frequency and types of NSSI among adjudicated male adolescents (n?=?103) and assessed the relationships between NSSI history, psychosocial concerns, coping responses, diagnoses, and functions within this population. Approximately two-thirds (66%) reported NSSI history. Participants with NSSI history reported poorer social adaptation and greater alienation and boredom, aggression, and emotional lability than controls. Youth with high-frequency NSSI were also more likely to utilize emotional discharge as an unhealthy coping response than controls. In addition, participants with high-frequency NSSI were more likely than controls to meet criteria for a mood or anxiety disorder. Function of NSSI primarily surrounded anxiety reduction/affect regulation, punishment, dissociation reduction, and social/sensation-seeking. NSSI appears to be prevalent among male adjudicated youths, and the findings suggest that the relationship between NSSI history, psychosocial concerns, coping responses, and functions is nuanced and could inform more calibrated assessment and treatment strategies.     

Human figure drawings of adjudicated and nonadjudicated adolescents

We investigated differences between human figure drawings of adjudicated and nonadjudicated adolescents. In addition, the relationship between human figure drawings and crime category (person, property, other, none) was examined for the adjudicated adolescents. Subjects consisted of four groups of adolescents (n = 25 each): adjudicated males, adjudicated females, nonadjudicated males, and nonadjudicated females. Human figure drawings were obtained from all subjects; they were scored using a system that was developed for use with adolescents. Kruskal-Wallis one-way analyses of variance (ANOVAs) were used to assess the effects of adjudication status and gender. There were 11 significant differences between adjudicated and nonadjudicated adolescents and 11 differences among the four groups. Results of Kruskal-Wallis ANOVAs also showed two significant differences among crime categories.     

Evaluation of an MMPI--a short form: implications for adaptive testing

Efforts to develop a viable short form of the MMPI (Hathaway & McKinley, 1943) span more than 50 years, with more recent attempts to significantly shorten the item pool focused on the use of adaptive computerized test administration. In this article, we report some psychometric properties of an MMPI-Adolescent version (MMPI-A; Butcher et al., 1992) short form based on administration of the first 150 items of this test instrument. We report results for both the MMPI-A normative sample of 1,620 adolescents and a clinical sample of 565 adolescents in a variety of treatment settings. We summarize results for the MMPI-A basic scales in terms of Pearson product-moment correlations generated between full administration and short-form administration formats and mean Tscore elevations for the basic scales generated by each approach. In this investigation, we also examined single-scale and 2-point congruences found for the MMPI-A basic clinical scales as derived from standard and short-form administrations. We present the relative strengths and weaknesses of the MMPI-A short form and discuss the findings in terms of implications for attempts to shorten the item pool through the use of computerized adaptive assessment approaches.     

The Fears of Youth in the 1990s: Contemporary Normative Data

This article reports the findings of a normative fear investigation involving a sample of 918 Australian children and adolescents, ranging in age from 718 years. The Fear Survey Schedule for Children and Adolescents-II (FSSC-II) was administered to determine self-reported prevalence, intensity, and content of fear. Consistent with past research, girls generally reported significantly higher levels of fearfulness than boys. Age differences also were found; younger children reported a higher intensity and a greater number of fears than older children and adolescents. Qualitative differences in normative fear were found, with younger children reporting more animal fears and older children reporting more fears relating to social evaluation or psychic stress. Significantly, although the specific content of children's and adolescents' normative fears in the 1990s (as compared with the 1960s) has changed (now including fear of AIDS and of nuclear war), the fears found to be most prevalent continue to relate to death and danger. These findings are discussed within the context of the prepotency and preparedness concepts of fear.     

Contributions of impulsivity and callousness in the assessment of adjudicated male adolescents: a prospective study

This study examined whether delinquent adolescents with low scores on personality scales related to callousness and impulsivity would show less antisocial behavior and better psychosocial functioning compared to those elevated on 1 or both scales. A group of 162 White and African American male adolescents, recently adjudicated in a southern youth court system, were assessed at baseline and at 18-month follow-up. Dependent variables included measures of antisocial and prosocial behaviors, days detained in juvenile detention, and symptoms of psychopathology. As hypothesized, adolescents low on both callousness and impulsivity spent fewer days detained and reported less antisocial behavior and fewer symptoms of psychopathology compared to those high on I or both scales. Finally, African American participants were detained for more days, but did not report significantly more antisocial behaviors or symptoms of psychopathology compared to the White adolescents. The results suggest that being low on callousness and impulsivity may serve a protective role for future delinquent behavior for both African American and White adolescents.     

Diffuse-Avoidance,Normative, and Informational Identity Styles: Using Identity Theory to Predict Maladjustment

Expanding on the identity status paradigm, this investigation uses 3 forms of identity styles (diffuse-avoidance, normative, and informational) to assess the association among identity and maladjustment. A sample of 2,001 junior and senior high school students in Calgary and Edmonton, Canada completed a self-report that included, among other questions, items assessing the 3 identity styles and degree of adjustment or maladjustment in conduct, hyperactivity, and emotional states. Avariety of analyses indicate that adolescents who are escaping identity formation through a diffuse-avoidance identity style are more likely to manifest conduct and hyperactivity disorders. In contrast, adolescents who establish commitments from prior generations through a normative-identity style, or who engage in an active informational-identity style, are less likely to manifest conduct and hyperactivity problem behavior. Few gender or age differences were observed, suggesting that the technique applied here can be useful with both genders and all ages of adolescents. This study is an initial investigation of contemporary adolescents attempts to escape the self.     

Use of the Suicide Probability Scale (SPS) with Adolescents

This study examined the utility of the Suicide Probability Scale (SPS) by comparing results obtained with a sample of 217 normal adolescents (M = 16.2 years) to the findings obtained in Cull and Gill's (1988 ) standardization effort. The present sample scored significantly higher than Cull and Gill's normative sample in SPS item, subscale, and total scores. In addition, the SPS generally failed to discriminate between the present, adolescent sample and Cull and Gill's inpatient psychiatric sample. Moreover, item-subscale correlations obtained for the present sample often differed from those reported by Cull and Gill, and factor analysis of SPS item scores failed to replicate Cull and Gill's four-factor solution. Findings suggest the need for caution when using the SPS to assess adolescent suicide potential and underscore the need for additional research regarding the instrument's efficacy in distinguishing between normal and suicidal adolescents.     

Deviancy and Normative Training Processes in Experimental Groups of Delinquent and Nondelinquent Male Adolescents

The goal of this study was to identify the predictors and the moderators of group characteristics that influence deviancy and normative training processes in delinquent male adolescents. The authors experimentally tested the effects of group composition on deviant talk interaction processes among groups in which all members presented delinquent behaviors (“pure” delinquent group condition), those that included adolescents with no delinquent behaviors (“pure” normative group condition), and adolescents with both profiles (“mixed” group condition). Participants were 70 male adolescents aged 15–18 (M = 16.5; 56% Caucasian), with a random assignment to groups. Data were collected among three group sessions (T1, T2, T3), one session a week, using videotape. Two contents of interactions were also measured: antisocial and normative stories, counterbalanced across sessions. Results showed a significant group effect for antisocial talk and its reinforcement, with less antisocial talk within the mixed group condition in comparison to the pure delinquent group condition. The topic of interaction was also observed as a predictor of antisocial talk, with less normative interactions and more antisocial talk associated with antisocial topics. Finally, time moderated some relations between experimental groups and talk. We conclude with a discussion of the implications of this work for future research on deviancy training processes. Aggr.

Perceptions of the Limitations of Confidentiality Among Chinese Mental Health Practitioners,Adolescents and Their Parents

The present study aims to (a) survey Chinese mental health professionals’ attitudes toward therapeutic confidentiality with adolescent patients in specific clinical situations, and (b) compare Chinese adolescents’ and parents’ beliefs about when most mental health professionals would breach confidentiality. A sample of 36 mental health practitioners, 152 parents, and 164 adolescents completed a survey to assess their opinions about when confidentiality should be breached in 18 specific clinical situations (e.g., an adolescent tells his or her therapist that he or she smoked a cigarette, had unprotected sex, or attempted suicide). Nearly half of the parents (46%) and adolescents (41%) and 78% of the therapists in our sample selected “yes” in response to the question of whether the principle of confidentiality applies to adolescents. However, 49% of parents indicated “no,” and 53% of adolescents indicated “not sure.” Compared to adolescents, parents were significantly more likely to believe that therapists would breach confidentiality for the high-breach-likelihood items. For the low-breach-likelihood items, adolescents and parents were significantly more likely than therapists to believe confidentiality should be breached. Results from this study provide data to inform the development, refinement, practical implementation, and communication of guidelines and recommendations specific to adolescents receiving psychotherapy in China.
