Recent evidence suggests that impulsivity and sensation seeking are not stable risk factors for substance use among adolescents and early adults but rather that they undergo ificant developmental maturation and change. Further, developmental trends of both personality facets may vary across individuals.

In the current investigation, we used longitudinal data from ages on 5, individuals drawn from the offspring generation of the National Longitudinal Survey of Youth CNLSY to examine whether inter-individual differences in intra-individual change in impulsivity and sensation seeking predicted the escalation of alcohol, marijuana, and cigarette use in adolescence and early adulthood.

Latent growth curve models revealed ificant individual differences in rates of change in both personality and substance use. Most importantly, age-related changes in personality were positively associated with individual differences in substance use change. Individuals who declined more slowly in impulsivity increased in alcohol, marijuana, and cigarette use more rapidly, whereas individuals who declined more slowly in sensation seeking increased more rapidly in alcohol use only.

Although risk for substance use across the population may peak during adolescence and early adulthood, this risk may be highest among those who decline more gradually in impulsivity. Although the exact nature and structure of undercontrolled personality continues to be a source of debate e. A breadth of research has found support for the role of impulsivity in adolescent and young adult alcohol use Dick et al. These developmental models i.

Consistent with Caspi and colleagues' maturity principlethese patterns, including increased social dominance, agreeableness, and conscientiousness and decreased neuroticism, tend to promote psychosocial maturity and improved functioning with age.

Recent research on developmental changes in personality has suggested that impulsivity and sensation seeking show diverging patterns of age-related change across adolescence and early adulthood. Behavioral and self-report evidence from cross-sectional Steinberg et al. In contrast, some of the same studies show that sensation seeking rises to a peak in mid-adolescence approximately age 16 before declining into adulthood Cauffman et al. The use and abuse of other substances follows similar patterns.

Thus, the emergence of substance use appears to coincide with the apex of mean-level personality risk. Missing from etiological theories derived from mean-level age-trends, however, is an acknowledgement of individual differences in both substance use and personality.

The adolescent emergence of substance use is far from universal across the population. As Romer has observed, although the prevalence of substance use—in addition to other forms of risk-taking such as physical aggression—may be higher among adolescents relative to adults, only a fraction of adolescents actually engage in such behaviors. Data from recent Monitoring the Future surveys confirm that a sizeable majority of adolescents and early adults do not smoke cigarettes or marijuana Johnston et al. These differential personality changes may be driven by both intrinsic differences and by life experiences.

Adolescence and early adulthood are rich with ificant social-role transitions e. Relevant to the current investigation, the mean-level developmental trends in impulsivity and sensation seeking emphasized by recent etiological models belie meaningful individual differences in intra-individual change. Harden and Tucker-Drob found ificant variability in trajectories of impulsivity and sensation seeking between the ages of 12 and 24 years old: Some adolescents demonstrate quite rapid declines in impulsivity and sensation seeking, whereas others demonstrate very slow declines.

An additional challenge for etiological theories of adolescent substance use derived from mean-level age-trends in personality e. That is, the initiation of substance use may often occur at the normative apex of sensation seeking, but the continuation and escalation of use in the population coincides with declines in both sensation seeking and impulsivity. Although these mean-level patterns appear contradictory, the recognition that individuals differ not only in their initial levels of impulsivity and sensation seeking, but also in their trajectories of personality change, permits a more comprehensive understanding of how personality may impact changes in substance use.

Just as greater impulsivity and sensation seeking at a given age predict greater substance use, individual-level deviations from normative age-trends may put some adolescents and early adults at particularly elevated risk for changes in substance use. That is, it is possible that individual-level personality and substance use trajectories covary, with those adolescents who decline in impulsivity and sensation seeking most gradually also experiencing the steepest increases in substance use. In sum, whereas adolescence and early adulthood may be, on averagea period of increased propensity for substance use, this risk may be highest among those who decline in impulsivity and sensation seeking most gradually.

Littlefield and colleaguesab have found that more rapid declines in impulsivity are associated with declining alcohol involvement through young adulthood. In a separate study, greater increases in sensation seeking during middle school predicted increased marijuana use during high school Crawford et al.

Although substance use peaks during late adolescence and early adulthood, evidence for the roles of changing impulsivity and sensation seeking during this crucial developmental period is lacking. To our knowledge, no study has directly tested associations between changes in the use of multiple substances and these two personality constructs through adolescence and early adulthood.

In the current investigation, we used 12 years of longitudinal data from the offspring generation of the National Longitudinal Survey of Youth CNLSY to test the role of personality change in individual differences in substance use from adolescence to early adulthood.

In particular, we tested whether variability in the development of impulsivity and sensation seeking related to variability in the development of alcohol, marijuana, and cigarette use across ages Our analyses focused on three key research questions: 1 are there individual differences in change in impulsivity and sensation seeking? A complex survey de was used to select a nationally representative sample of 3, households containing 6, youth aged years as of December 31, As of11, children were identified as having been born to 6, NLSY79 women.

After weighting for sample selection, the average NLSY79 woman has had 1. The current project uses data from a subsample of 5, adolescents and young adults who reported on their impulsivity, sensation seeking, and alcohol, marijuana, and cigarette use at least once between the ages of 15 and Although some participants may have initiated substance use prior to age 15, the young adult substance use assessments differed from the measures administered to participants under age 15, rendering the inclusion of younger children impossible.

Because children were assessed biennially, all data were analyzed using six two-year age groups: year olds, years olds, year olds, years olds, year olds, and years olds. As displayed in greater detail in Table 1 Wf seeks wm for personal growth, of the 5, participants included in the present analyses, only a subset provided data at each age group. First, the interviews began inexcluding from the age interviews the relatively small of offspring born prior to Second, some of those eligible did not complete the age interview; these individuals differed modestly from participants on maternal demographic variables.

Empty cells ify that a particular birth cohort was not assessed during that age range. This final source is a well-documented potential contributor of bias to the CNLSY sample: Because not all NLSY79 mothers have completed their childbearing and not all offspring have completed adolescence, the current CNLSY data over-represent the earliest cohort of participants, who were born to relatively young mothers Turley, Younger mothers, in turn, systematically differ from women who delay childbearing on socioeconomic and behavioral variables that may be relevant for personality and substance use in their offspring Harden et al.

Socioeconomic status SES was measured using mother-reported total family income, including government support and food stamps but excluding income received by unmarried cohabitating partners, when the mother was 30 years old.

Composite scores on the ASVAB based on the word knowledge, paragraph comprehension, math knowledge, and arithmetic reasoning subtests were standardized and converted to a percentile score. This commonly used, Wf seeks wm for personal growth, and valid measure included 12 items assessing the frequency with which respondents engaged in delinquent acts ranging from destroying property to attacking another person to selling hard drugs. As a measure of maternal internalizing symptoms, mothers completed the Center for Epidemiological Studies-Depression scale in at ages Radloff, This widely used measure comprises 20 items such as I felt hopelessI felt sadand I thought my life had been a failure.

We used a latent variable approach to the measurement of impulsivity and sensation seeking. Impulsivity was assessed by youth self-report on three indicator items: I often get in a jam because I do things without thinking; I think that planning takes the fun out of things ; and I have to use a lot of self-control to keep out of trouble. Similarly, sensation-seeking was assessed by youth self-report on the following three indicator items: I enjoy taking risks; I enjoy new and exciting experiences, even if they are a little frightening or unusual ; and life with no danger in it would be too dull for me.

Although impulsivity and sensation seeking were positively associated across all assessments r s ranging from. As has been ly reported, the CNLSY measures of impulsivity and sensation seeking demonstrate strong validity. Substance use was measured using self-reported frequencies of alcohol, marijuana, and cigarette use, each of which was assessed at every assessment wave.

Across all time-points, alcohol use scores averaged 3. Alcohol abstainers comprised between Abstainers were coded as 1 did not drink. Across all time-points, marijuana use scores averaged 0. Pastday abstainers comprised between Marijuana and cigarette abstainers were coded as 0 Never used.

See Table 2 for correlations among substance use variables and Table 3 for correlations between personality and substance use variables.

Personality scores are means across the three items each for impulsivity and sensation seeking. Data were analyzed in three steps. Second, we fit linear and non-linear univariate models of change in each of the substance use outcomes and personality constructs in order to determine which model best represented the shape of change in each variable over time. Third, we tested for correlated changes among impulsivity, sensation seeking, and substance use in a series of three multivariate LGMs one each for alcohol, marijuana, and cigarette use.

To avoid redundancy, we report model parameters for the multivariate models only. All models included adolescent gender and ethnicity, along with maternal SES, years of education, cognitive ability, age at first birth, delinquency, and depression, as exogenous covariates. An impulsivity model in which factor loadings and thresholds for each item were constrained to be equal across time i. Given the sensitivity of this test in large sample sizes, however, we also examined change in other model fit indices.

Further, inspection of parameter values suggested that measurement appeared relatively invariant across time. Standardized factor loadings for each item, for example, differed by less than 0. We therefore modeled impulsivity with strong measurement invariance in all subsequent analyses.

Inspection of the unconstrained models suggested that measurement was largely similar across time, with standardized factor loadings varying by less than. We again selected the strong measurement invariance model for all subsequent sensation seeking analyses.

Our next analytic step was to model change over time in personality and substance use using univariate Latent Growth Curve Models LGMs. LGMs serve the dual purpose of determining average patterns of change across time and estimating how much individuals' trajectories deviate from mean trends.
