Differential Determinants of Young Adult Substance Use and High‐Risk Sexual Behavior1

This investigation evaluated how personality traits, self‐efficacy, and outcome expectancies differentially relate to young adult substance use and high‐risk sex. Experiments I (N= 481) and 2 (N= 73) report the development of a new questionnaire to assess self‐efficacy for substance use and sexual behavior. Experiment 3 (N= 375) tested self‐efficacy, outcome expectancies, and trait measures of social conformity and sensation seeking as correlates of substance use and high‐risk sex. Using structural equation modeling, cross‐sectional analyses revealed that positive outcome expectancies had the largest association with substance use, whereas self‐efficacy had the largest association with sexual behavior. Further, personality traits were related to substance use and sexual behavior indirectly through outcome expectancies, with social conformity also having a direct effect on behavior. When examined longitudinally, past alcohol and drug use served as the final pathway by which expectancies and personality impacted substance use, whereas past behavior, self‐efficacy, and social conformity all contributed to high‐risk sex. Results support the utility of different models for explaining, and possibly preventing, young adult substance use and high‐risk sex.     

An 8-year study of multiple influences on drug use and drug use consequences

Multiple long-term influences on young adult drug use and abuse were tested within an interactionist perspective using latent-variable causal models. Intrapersonal influences included early drug use and social conformity. Proximal interpersonal influences were captured by perceived peer drug use, perceived adult drug use, and family disruption. More distal influences included perceptions of community approval or disapproval for drug use. Outcome measures included not only use of drugs but also disruptive drug use (getting high at work or school) and self-admitted problems with drugs. Data were obtained from 654 participants at three equally spaced time points during an 8-year longitudinal study that began when the subjects were in junior high school. Confirmatory factor analyses were used to test the adequacy of the hypothesized measurement model. Subsequently, a structural equation, or path model, was used to examine the across-time relations among the latent and manifest variables. Stability effects were found for all repeatedly measured latent variables across the 4-year spans. Social conformity strongly influenced other latent variables across time. Early drug use and perceived adult drug use were prominent predictors of young adult drug use, whereas prior drug use predicted disruptive drug use and a lack of social conformity predicted problems with drug use. Early adult alcohol use predicted later disruptive drug use and problems with drug use. Perceived adult drug use generally influenced later alcohol use, whereas peer drug use influenced later cannabis and hard-drug use. Implications for prevention and treatment using a multicausal interactionist perspective are discussed.     

Transactional models between personality and alcohol involvement: a further examination

Although correlated changes between personality and alcohol involvement have been shown, the functional relation between these constructs is also of theoretical and clinical interest. Using bivariate latent difference score models, we examined transactional relations (i.e., personality predicting changes in alcohol involvement, which in turn predicts changes in personality) across two distinct but overlapping developmental time frames (i.e., across college and during young adulthood) using two large, prospective samples. Across college, there was some evidence that alcohol involvement predicted changes in personality; however, these findings were limited to models that included more proximal measures of alcohol use. When examined across a longer timeframe, we found no evidence that alcohol involvement significantly predicted changes in personality but found some evidence that personality predicted changes in alcohol use. We did find reliable evidence of correlated changes between personality and alcohol use, especially during emerging adulthood. The findings from our datasets highlight that the impact of alcohol involvement on personality change may be limited to shorter intervals during specific developmental time-frames and that the relation between changes in personality and alcohol involvement may be best viewed from a noncausal perspective.     

Adolescent Precursors of Intensity of Marijuana and Other Illicit Drug Use Among Adult Initiators

This study examined (a) adolescent psychosocial risk factors for frequency (intensity) of marijuana use and for other illicit drug use among those who started using these drugs in early adulthood (adult initiators) and (b) the protective role of parent-adolescent relations in reducing or preventing drug use when adolescents enter early adulthood. The study's participants were male and female youth from a longitudinal prospective study. The participants' mean ages were 17 and 22 years at late adolescence and early adulthood, respectively. Independent measures assessed personality, parental, peer, and self-drug-use factors during late adolescence; dependent measures assessed frequency of marijuana use and other illicit drug use during early adulthood for initiators of the respective drug categories. The authors found that intensity of marijuana use was directly associated with the personality, parental, and self-drug-use domains and indirectly associated with the peer domain. Intensity of other illicit drug use was directly associated with personality and self-drug use. Analyses also revealed that some parent-adolescent relations factors buffered the effects of risk factors for both marijuana and other illicit drug-use intensity, whereas others enhanced the effects of protective factors against other illicit drug-use intensity. The results indicate that there are both commonalities and differences in precursors of marijuana and other illicit drug-use intensity among initiators of these drugs during early adulthood.     

Multiple protective and risk factors for drug use and abuse: cross-sectional and prospective findings.

A conceptual elaboration was developed that incorporates many risk and protective factors, and both direct and moderating (buffering) influences on drug involvement were tested. From prospective data, 14 factors related to drug use were selected and assigned empirically to either a multiple protective index (PFI) or a risk factor index (RFI). Analyses examined the relationships of the RFI, PFI, and their interaction on measures of cigarette, alcohol, cannabis, cocaine, and hard drug use cross-sectionally in late adolescence and later in young adulthood. These same variables were used to predict alcohol, cannabis, and cocaine abuse 8 years later. Vulnerability as measured by the RFI, PFI, and their interaction was highly associated with drug use in adolescence, moderately associated with certain types of drug use in young adulthood, and strongly associated with heightened drug problems in adulthood.     

Adolescent precursors of intensity of marijuana and other illicit drug use among adult initiators

This study examined (a) adolescent psychosocial risk factors for frequency (intensity) of marijuana use and for other illicit drug use among those who started using these drugs in early adulthood (adult initiators) and (b) the protective role of parent-adolescent relations in reducing or preventing drug use when adolescents enter early adulthood. The study's participants were male and female youth from a longitudinal prospective study. The participants' mean ages were 17 and 22 years at late adolescence and early adulthood, respectively. Independent measures assessed personality, parental, peer, and self-drug-use factors during late adolescence; dependent measures assessed frequency of marijuana use and other illicit drug use during early adulthood for initiators of the respective drug categories. The authors found that intensity of marijuana use was directly associated with the personality, parental, and self-drug-use domains and indirectly associated with the peer domain. Intensity of other illicit drug use was directly associated with personality and self-drug use. Analyses also revealed that some parent-adolescent relations factors buffered the effects of risk factors for both marijuana and other illicit drug-use intensity, whereas others enhanced the effects of protective factors against other illicit drug-use intensity. The results indicate that there are both commonalities and differences in precursors of marijuana and other illicit drug-use intensity among initiators of these drugs during early adulthood.     

Relationships Between Future Orientation, Impulsive Sensation Seeking, and Risk Behavior Among Adjudicated Adolescents

Because of high levels of risk behavior, adjudicated adolescents are at high risk for negative health outcomes such as nicotine and drug addiction and sexually transmitted diseases. The goal of this article is to examine relationships between future orientation and impulsive-sensation-seeking personality constructs to risk behaviors among 300 adjudicated adolescents. Significant relationships between impulsive sensation seeking and future orientation were found for several risk behaviors. Individuals with more positive future orientation were less likely to use marijuana, hard drugs, alcohol during sex, had fewer alcohol problems, had lower levels of alcohol frequency and quantity of use, and perceived greater risks associated with such behaviors. Higher impulsivity reliably predicted alcohol problems, alcohol use, condom use, and cigarette smoking.     

Inter‐ and intrapersonal processes underlying authoritarianism: The role of social conformity and personal need for structure

Several personality constructs have been theorised to underlie right‐wing authoritarianism (RWA). In samples from New Zealand and Germany (Ns = 218, 259), we tested whether these constructs can account for specific variance in RWA. In both samples, social conformity and personal need for structure were independent predictors of RWA. In Sample 2, where also openness to experience was measured, social conformity and personal need for structure fully mediated the impact of the higher‐order factor of openness on RWA. Our results contribute to the integration of current approaches to the personality basis of authoritarianism and suggest that two distinct personality processes contribute to RWA: An interpersonal process related to social conformity and an intrapersonal process related to rigid cognitive style.

Acceptance of cosmetic surgery: Personality and individual difference predictors

This study examined the association between several attitudinal constructs related to acceptance of cosmetic surgery, and participant demographics, personality, and individual difference variables. A sample of 332 university students completed a battery of scales comprising the Acceptance of Cosmetic Surgery Scale (ACSS) and measures of the Big Five personality factors, self-esteem, conformity, self-assessed attractiveness, and demographics. Multiple regressions showed that the predictor variables explained a large proportion of the variance in ACSS factors (Adj. R² ranging between .31 and .60). In addition, structural equation modelling revealed that distal factors (sex and age) were generally associated with acceptance of cosmetic surgery through the mediate influence of more proximate variables (in the first instance, the Big Five personality factors, followed by self-esteem and conformity, and finally self-assessed attractiveness). These results allow for the presentation of a preliminary model integrating personality and individual differences in predicting acceptance of cosmetic surgery.     

Pathways of peer relationships from childhood to young adulthood

This study examined trajectories of peer social preference during childhood and personality assessed in early adolescence in relation to trajectories of friendship quality during early adulthood. Participants (N = 585) were followed from ages 5 to age 23. At ages 5 to 8, peers provided sociometric nominations; at age 12 participants reported their own personality characteristics; from ages 19 to 23 participants rated their friendship quality. Latent growth modeling revealed that trajectories characterized by high levels of childhood peer social preference were related to trajectories characterized by high levels of early adulthood friendship quality. Early adolescent personality characterized by extraversion and conscientiousness predicted higher friendship quality at age 19, and conscientiousness predicted change in friendship quality from ages 19 to 23. This study demonstrates that peer relationships show continuity from childhood to early adulthood and that qualities of core personality are linked to the development of adult friendships.     

Are anxiety and depression just as stable as personality during late adolescence? Results from a three-year longitudinal latent variable study

Although considerable evidence shows that affective symptoms and personality traits demonstrate moderate to high relative stabilities during adolescence and early adulthood, there has been little work done to examine differential stability among these constructs or to study the manner in which the stability of these constructs is expressed. The present study used a three-year longitudinal design in an adolescent/young adult sample to examine the stability of depression symptoms, social phobia symptoms, specific phobia symptoms, neuroticism, and extraversion. When considering one-, two-, and three-year durations, anxiety and personality stabilities were generally similar and typically greater than the stability of depression. Comparison of various representations of a latent variable trait-state-occasion (TSO) model revealed that whereas the full TSO model was the best representation for depression, a trait stability model was the most parsimonious of the best-fitting models for the anxiety and personality constructs. Over three years, the percentages of variance explained by the trait component for the anxiety and personality constructs (73-84%) were significantly greater than that explained by the trait component for depression (46%). These findings indicate that symptoms of depression are more episodic in nature, whereas symptoms of anxiety are more similar to personality variables in their expression of stability.     

Collegiate heavy drinking prospectively predicts change in sensation seeking and impulsivity

Recent models of alcohol use in youth and young adulthood have incorporated personality change and maturation as causal factors underlying variability in developmental changes in heavy drinking. Whereas these models assume that personality affects alcohol use, the current prospective study tested the converse relation. That is, we tested whether, after accounting for the effect of traits on drinking, collegiate heavy drinking in turn predicted individual differences in change in alcohol-related aspects of personality. We also examined whether affiliation with heavy-drinking peers better accounted for this relation. Following a cohort of recent high school graduates (N=1,434) through the college years, we found evidence for transactional relations between heavy drinking and changes in impulsivity and sensation seeking. Both traits predicted increases in heavy drinking, but more important, heavy drinking predicted increases in sensation seeking and impulsivity. In final models, social influences did not underlie the effect of heavy drinking on increases in sensation seeking and impulsivity. The results of this investigation suggest that collegiate heavy drinking may negatively and pervasively impact a wide range of behaviors because of its effect on personality change.     

Bidirectional relations between different forms of prosocial behaviors and substance use among female college student athletes

Bidirectional, longitudinal relations between alcohol and marijuana use and prosocial behaviors in women college student athletes were examined. Participants were 187 female college students (M_age = 19.87 years; 91% White) who completed questionnaires on their use of marijuana and alcohol, and six forms of prosocial behaviors across 6 years (2004–2010). The findings yield overall evidence that earlier marijuana use predicted lower levels of most specific forms of prosocial behaviors for women athletes in later young adulthood. Early expressions of altruistic behaviors predicted less marijuana use in later young adulthood. Expression of public prosocial behaviors early in young adulthood predicted higher levels of hazardous drinking in late young adulthood. These novel findings have important implications for links between prosocial development and substance use in women college athletes.     

The effects of familial risk, personality, and expectancies on alcohol use and abuse

This study tested a structural model of the association between familial risk, personality risk, alcohol expectancies, and alcohol abuse in a sample of 224 young adult offspring of alcoholics and 209 offspring of nonalcoholics. The results provided support for 2 personality-risk pathways, a social deviance proneness and an excitement/pleasure seeking path, that accounted for a significant portion of the association between a familial alcoholism and alcohol abuse. The path from familial alcoholism to social deviance proneness lead directly to alcohol problems. The path from familial alcoholism to excitement/pleasure seeking was associated with increased drinking, which, in turn, was associated with alcohol problems. Positive alcohol expectancies accounted for part of the association between excitement seeking and alcohol use. The results suggest 2 different biopsychosocial mechanisms that elevate risk for abuse in the offspring of alcoholics.     

Smoking involvement during adolescence among African Americans and Puerto Ricans: risks to psychological and physical well-being in young adulthood

The major aim of this study was to examine the longitudinal association between adolescent smoking involvement and self-reported psychological and physical outcomes in young adulthood. Participants included 333 African Americans and 329 Puerto Ricans who were surveyed in 1990 in their New York City schools and interviewed in 1995 and 2000-2001, primarily in their homes. The psychological outcomes included ego integration, symptoms of depression, anxiety, and interpersonal difficulty. The physical health measures included a general health rating, number of illnesses, and symptoms of ill health. Also, three scales measured problems due to alcohol, marijuana, and other illicit drug use. Smoking involvement varied by age, sex, and ethnicity but not by socioeconomic status nor by late adolescent parental status. Analysis showed that the relationships between adolescent smoking involvement and psychological and physical health problems in young adulthood remained significant even with control on demographic factors, earlier levels of the outcome variables, and marijuana use. The relationships between smoking behavior and problems with alcohol, marijuana and other illicit drug use were particularly strong. Thus, adolescent smoking seems to have a wide range of clinical implications for young adulthood.     

Cognitive biases and alcohol use in adolescence and young adulthood: The moderating role of gender,attentional control and inhibitory control

The present study investigated the cross-sectional associations between cognitive biases (i.e., attentional bias and approach bias) and alcohol use and investigated the moderating role of gender, attentional control and inhibitory control. The sample consisted of 94 adolescents and young adults (52.1% boys) between 15.3 and 20.8 years old (M_age = 18.0, SD = 1.1) who reported drinking alcohol in the past three months. A stronger approach bias was related to higher alcohol use, albeit only among boys. Furthermore, the association between attentional bias and alcohol use was moderated by attentional control; the lowest alcohol use was found in adolescents with low attentional bias and high attentional control, suggesting protective effects of both variables. The present study replicates and extends the results of studies on cognitive biases and addiction in adolescence and young adulthood.     

Demographic, clinical, and personality variables associated with male prostitution by choice.

This research compared demographic, clinical and personality variables in a sample of 15 male prostitutes and 15 nonprostitutes from the same cohort. Unlike previous samples of male prostitutes, these young men specifically reported that they were involved by choice, primarily to earn extra money. Significant findings included heavier drug and alcohol use, more limited vocational success and aspirations, and greater alcohol use among family members of male prostitutes. Male prostitutes were also more likely to identify themselves as drug or alcohol addicted. No significant differences were found in personality characteristics between the two groups, although there was limited support for the hypothesis that male prostitutes are more antisocial.     

A Longitudinal Investigation of Egoistic and Moralistic Self-Enhancement

This study used a 3-wave longitudinal design to investigate stability and change of egoistic and moralistic self-enhancement. Participants (n = 195) were followed for 6 years, from late adolescence (age 15) to emerging adulthood (age 21). A significant degree of rank-order stability was found that reveals a reasonable continuity in the individuals’ relative standing on measures of egoistic and moralistic self-enhancement. Latent growth curve analysis was used to track the developmental trajectories of the examined constructs. Findings revealed that egoistic self-enhancement is stable from 15 to 21 years, whereas moralistic self-enhancement slightly decreases during the same developmental period. Cross-lagged models were used to examine the reciprocal relations between self-enhancement and the Big Five personality traits. No prospective effects were found between the constructs, which develop independently from late adolescence to young adulthood, showing only synchronous associations. Implications for personality research and assessment are discussed.     

Determinants of early- vs late-onset dental fear in a longitudinal-epidemiological study.

A longitudinal investigation of risk factors for early- and late-onset dental fear was conducted. Early-onset dental fear was related to conditioning experiences (indexed via caries level and tooth loss), service use patterns, stress reactive personality and specific beliefs about health professionals. Late-onset dental fear was related to aversive conditioning experiences, irregular service use and an external locus of control. In contrast to recent findings for dental anxiety, personality factors were not strongly related to the onset of dental fear in young adulthood. The key role played by conditioning events in the development of both early- and late-onset dental fear was confirmed. Conditioning events appear to play a different role in the development of dental fear vs dental anxiety. This may reflect important, but largely ignored differences between these two closely-related constructs. Interventions for early-onset dental fear should aim to modify both the dental fear and the personality vulnerabilities that may contribute to the development of dental fear early in the life-course.
