Protective and risk influences of drug use among a multiethnic sample of adolescent boys.

A measurement model was analyzed to demonstrate a differential distribution and cumulative exposure to psychosocial risk and protective influences of adolescent drug use among ethnically-diverse adolescent samples. The sample included U.S.-born (US) Latino (N = 837), foreign-born (FB) Latino (N = 447), White (N = 632), and African American (N = 618) adolescent boys. Psychological Distress, Peer Drug Use, and Adolescent Drug Use were significantly positively correlated with Peer Drug Use and Adolescent Drug Use. In contrast, Family, School, law abidance, and guilt were significantly negatively correlated with Peer Drug Use and Adolescent Drug Use. Multiple group analyses indicated significant similarities and differences among US and FB Latinos, and Whites. Implications for early prevention, multi-level interventions, and suggestions for future research are discussed.

Child and familial pathways to academic achievement and behavioral adjustment: a prospective six-year study of children with and without ADHD.

This longitudinal study examined familial and child predictors of academic achievement and behavioral adjustment. Participants included 115 children with ADHD and 59 normative comparisons. Data analyses spanned three assessment waves from elementary- through secondary-school grades. We evaluated the degree to which child and familial factors present during middle school mediated relationships between childhood ADHD, subsequent academic achievement, and behavioral adjustment during high school. We found that emotional and behavioral well-being of ADHD children during middle school mediated relations between childhood ADHD and adverse academic and behavioral outcomes during high school. In addition, familial factors in middle school years predicted the behavioral adjustment of children in both the ADHD and non-ADHD groups. Academic achievement during high school was strongly associated with previous achievement levels. Our results provide support for tailoring preventive interventions to the unique needs of children with ADHD and their parents at various stages of adolescent development.

Intergenerational cycle of maltreatment: a popular concept obscured by methodological limitations.

OBJECTIVE: The intergenerational transmission of child maltreatment is a controversial subject. Much of existing research is plagued with at least three fundamental weaknesses: (1) using case status to define subjects: (2) adopting a dichotomous perspective that does not consider the reality of maltreatment on various continua; and (3) using operational definitions that fail to differentiate between maltreatment subtypes. We controlled for these problems and examined the structure of child maltreatment and its influence on later parenting practices in an ethnically-diverse community sample. METHOD: Data from a community sample of parents (N = 383) were analyzed with a Structural Equation Modeling methodology. Reliable and valid continuous measures of child maltreatment (Child Trauma Questionnaire) and parenting practices (Parental Acceptance and Rejection Questionnaire) were used. RESULTS: Results revealed a moderately strong effect from a general factor of Child Maltreatment to a general factor of Poor Parenting for both mothers and fathers, supporting a common dysfunction transmission process. For mothers. Family Neglect by itself also led to poor parenting, and sexual abuse as a child led to aggressive parenting. For fathers, Child Maltreatment had a different structure, as sexual abuse was distinct from the factors of Family Abuse and Family Neglect. Also, for fathers, sexual abuse led to rejecting parenting practices. CONCLUSIONS: This study supports the intergenerational cycle of child maltreatment hypothesis in such a way that several weaknesses in much of existing research were controlled. Clinical implications and potential mechanisms of transmission are discussed.

The drug-crime nexus in a community sample of adults.

The authors tested several theories using prospective data to explain the associations between drug abuse and crime in a community sample of 470 adults. Polydrug problems in early adulthood predicted both criminal behavior and polydrug problems in adulthood. Consequences of drug problems as a young adult included arrests and convictions for drug-related offenses, property damage, and driving under the influence of other drugs. Predictors of later polydrug problems included thefts, driving under the influence of alcohol and other drugs, arrests and convictions for drug-related offenses, and a lack of support for drug problems. Theoretical implications of these findings are discussed.

Alcohol involvement and dysphoria: a longitudinal examination of gender differences from late adolescence to adulthood.

Although numerous investigations have examined the relations between alcoholism and depression, differing results have emerged. Major limitations in existing work are that it uses clinical samples and is cross-sectional in nature. Using prospective data from a community sample assessed during 3 developmental periods (late adolescence, young adulthood, and adulthood), these complex relations were examined with structural equation modeling. Results show distinct gender differences between alcohol involvement and dysphoria. For women these 2 processes were related from late adolescence to adulthood, and this relation was reflected in a higher order construct that was stable over time. For men alcohol involvement and dysphoria were unrelated during late adolescence but converged over time. Reciprocal relations between alcohol involvement and dysphoria were found for both men and women.

Gender differences in the prediction of problem alcohol use in adulthood: exploring the influence of family factors and childhood maltreatment.

OBJECTIVE: The purpose of this study was to contrast men and women in prospective relationships among family-oriented and alcohol-related variables obtained during adolescence, childhood physical, emotional and sexual abuse collected retrospectively, and later adult problem alcohol use. METHOD: In structural equation models, early family processes (support/bonding, parent drug-use problems, parental divorce and childhood maltreatment) and prior alcohol use simultaneously predicted adult problem alcohol use at two later time points in a longitudinal community sample of 426 (305 female) adults. RESULTS: Significant relationships were found among family processes, childhood maltreatment, and problem alcohol use within time and longitudinally for both men and women. Greater family support/bonding during adolescence predicted less problem alcohol use in adulthood. Men and women who experienced sexual abuse as a child reported more problem alcohol use in adulthood. Problem alcohol use was stable across time. Men reported more problem alcohol use in adolescence and adulthood, and women reported more early sexual abuse. These results contradict those that find no significant relationships between childhood abuse and subsequent alcohol-related problems. Parental drug use problems during the participant's adolescence did not directly predict problem alcohol use in adulthood. The relationship was more indirect in that parental drug use was associated with family-related concomitants that in turn were significant predictors of more problem alcohol use in adulthood. CONCLUSIONS: The strong stability for problem alcohol use across the three time periods is a signal that alcohol use in adolescence should not be ignored; furthermore, family dynamics need attention in addressing problem alcohol use.

Prospective relationships between drug problems and work adjustment in a community sample of adults.

The prospective relationships between drug problems and work adjustment (e.g., job instability, job satisfaction) were examined in a community sample of 470 adults. Polydrug problems (alcohol, marijuana, and cocaine problem drug use) were both predictors and consequences of work adjustment. In partial support of the impaired functioning theory, polydrug problems predicted reduced job satisfaction 4 years later. Supporting the work-related strain theory, early job instability predicted polydrug problems 4 years later. In support of the theory of general deviance, low social conformity predicted later job instability. Finally, supporting social support theory, early support for drug problems reduced polydrug problems and increased job satisfaction 4 years later.

Sociodemographic and individual predictors of alcohol policy attitudes: results from a US probability sample.

OBJECTIVE: Public views on alcohol policies have facilitated legislative change. Given limited resources, however, policy makers and prevention advocates cannot make haphazard attempts to mobilize public resources. This investigation reports sociodemographic and individual traits predicting attitudes on alcohol policies designed to reduce underage alcohol consumption. Previous studies have examined single-item measures of alcohol policy. We examined predictors of multi-item scales measuring five core dimensions of alcohol policy. METHODS: A survey of public attitudes on alcohol policies was administered to a US national probability sample of 7021 adults. RESULTS: Women, infrequent drinkers, and adults with greater knowledge about or concern for youth exhibited the greatest support across five alcohol policy scales. Older adults favored policies that restrict alcohol use in public places, whereas younger adults favored an increase in alcohol taxes to address underage alcohol use. CONCLUSIONS: Individual factors such as alcohol use frequency and concern for youth explained larger proportions of variance in alcohol policy attitudes than did sociodemographic factors. Consistent with previous research, political orientation, parental status, employment status, and marital status did not predict attitudes on alcohol policy.

Adolescent drug use in Mexico and among Mexican American adolescents in the United States: environmental influences and individual characteristics.

The authors compared high school students in Baja California Norte (BCN), Mexico (n = 775), with Mexican American students in Los Angeles (LA), California (n = 516). The students' use of cigarettes, alcohol, marijuana, cocaine, inhalants, and other illicit drugs were compared, because these vary by gender, country, and their age of first drug use and are influenced by demographic variables, individual characteristics, and environmental influences. More BCN students than LA students had used alcohol, but more LA than BCN students had used illicit drugs and initiated drug use earlier. When demographic variables were influential, they were most powerful and increased the risk for drug use more than environmental factors or individual characteristics. Environmental factors were most influential for boys' drug use, whereas environmental and demographic variables were most influential for girls' drug use.

A multidimensional approach to homosexual identity.

The existing developmental stage models of homosexual identity do not consider the diversity of human sexual experience. The stage models stem from an essentialist perspective, in which the process of homosexual identity formation is largely a matter of becoming aware of one's underlying, or real, sexual orientation. Once homosexual orientation is identified, the only legitimate outcome is to develop homosexual identity and eventually incorporate that identity as one aspect of the total self. In this paper, we are concerned with those people for whom the stage models are inadequate in describing their experience of sexual identity development. The social constructionist perspective holds that the process of identity formation is a continual, two-way interactive process between the individual and the social environment, and that the meanings the individual gives to these factors influence the development of self-constructs and identity. Sexual identity develops within this contextual framework and, because it is influenced by continual interaction, is fluid over time and experience, throughout one's life. Our model does not rely on the existing developmental models of homosexual identity; rather, our model looks at desire, behavior, and identity as three separate constructs related to sexual identity. We posit that from the social constructionist viewpoint, there is in fact no true endpoint to sexual identity development.

Implicit cognition and HIV risk behavior.

Implicit cognition theory differs from most other approaches to health behavior in that it emphasizes neurobiologically plausible and experimentally documented memory association processes rather than rational decisions, considerations of pros and cons, or beliefs. The present study of adults from a community population investigated the predictive effects of implicit cognition, as well as behavioral and personality variables (sensation seeking, hostility, conscientiousness, and polydrug use), on risky sexual behaviors (lack of condom use, sex after drug use, and multiple sexual partners). In addition, this study simultaneously investigated the predictors in both a high-risk and a low-risk sample. Results showed that the implicit cognition indicator was a significant, independent predictor of lack of condom use in the high-risk sample. Polydrug use and sensation seeking also had important predictive effects. The results encourage more research on implicit cognition in health behavior and further document links among drug use, personality, and HIV risk behavior.

Predictors of polydrug use among four ethnic groups: a 12-year longitudinal study.

We examined adolescent risk and protective constructs associated with adult polydrug use among four ethnic groups. Both mean and relational differences among the constructs were examined by ethnic group. Teenage polydrug use was a significant predictor of adult polydrug use for Caucasians, African-Americans, and Latinos. Although this relationship was not evident for Asians, teenage alcohol use increased adult cigarette use, and early religiosity increased adult alcohol use. Early parental support/bonding predicted less adult Polydrug Use for Caucasians. For Latinos, general social conformity and low liberalism decreased cigarette use as an adult. In general, the implications of the results are that prevention strategies should emphasize the reduction of teenage drug use to decrease adult polydrug use among Caucasians, Latinos, and African-Americans. Future research should examine other possible risk and protective conditions related to adult polydrug use among diverse populations.

Adolescent drug use and adult drug problems in women: direct, interactive, and mediational effects.

The authors studied effects of variables assessed in adolescence on problems from drug use in adulthood in a community sample of women. One focus of this 13-year longitudinal study was moderators, which were hypothesized to exacerbate, or attenuate, the effects of early drug consumption on later drug problems. Potential moderators were sensation seeking, social conformity, academic orientation, parental support, depression, and drug problems in parents. Direct and mediating effects of these variables, as well as of drug consumption, were also evaluated. Results showed that most of the significant effects involved sensation seeking and social conformity. In addition, adolescent drug use significantly predicted adult polydrug problems. The effects of sensation seeking are consistent with the view that this variable reflects a sensitivity to drug use, which makes it more likely that drug use gets translated into drug abuse.

Sexual risk behavior among youth: modeling the influence of prosocial activities and socioeconomic factors.

Sexual activity among high-school-aged youths has steadily increased since the 1970s, emerging as a significant public health concern. Yet, patterns of youth sexual risk behavior are shaped by social class, race, and gender. Based on sociological theories of financial deprivation and collective socialization, we develop and test a model of the relationships among neighborhood poverty; family structure and social class position; parental involvement; prosocial activities; race; and gender as they predict youth sexual risk behavior. We employ structural equation modeling to test this model on a cross-sectional sample of 370 sexually active high-school students from a midwestern city; 57 percent (n = 209) are males and 86 percent are African American. We find that family structure indirectly predicts sexual risk behavior through neighborhood poverty, parental involvement, and prosocial activities. In addition, family class position indirectly predicts sexual risk behavior through neighborhood poverty and prosocial activities. We address implications for theory and health promotion.

PIP: Sexual activity among high school-aged youths has increased steadily since the 1970s, with more than half of high school students in 1990 being sexually active, and only about half of those individuals reporting that they or their sex partners used condoms during their most recent sexual intercourse. Patterns of youth sexual risk behavior and their consequences are, however, partly defined by social class, race, and gender. Based upon sociological theories of financial deprivation and collective socialization, the authors develop and test a model of the relationships among neighborhood poverty; family structure and social class position; parental involvement; prosocial activities; race; and gender as they predict youth sexual risk behavior. Structural equation modeling is used to test the model upon a cross-sectional sample of 209 male and 161 female sexually active high school students from Michigan. The students are 86% Black and of mean age 14.63 years. Family structure was found to indirectly predict sexual risk behavior through neighborhood poverty, parental involvement, and prosocial activities, while family class position indirectly predicts sexual risk behavior through neighborhood poverty and prosocial activities. Implications for theory and health promotion are considered.

Memory association and personality as predictors of alcohol use: mediation and moderator effects.

We investigated the nature of the effects of memory associations on alcohol use and abuse. First, we determined if effects of memory associations on drinking problems are mediated entirely through the frequency of alcohol consumption or, alternatively, if such effects are more direct. Second, personality traits were assessed to evaluate whether they were confounded with memory association in their effects or whether they might moderate the effects of memory associations on alcohol use and abuse. The results showed that memory association measures directly and independently predicted alcohol consumption; these measures indirectly predicted problems from drinking, including drunk driving. None of the assessed personality variables moderated the predictive effects of memory association. The results are consistent with the view that memory associations influence behavior through cognitive processes that are not affected by personality traits or by cognitions emanating from such traits.

The use of synthetic lysine in the diet of lactating sows.

We conducted an experiment to determine the proportion of the lysine requirement of lactating sows that can be met using L-lysine x HCl. A total of 247 Pig Improvement Company (PIC) sows (parity one to four) were randomly allotted to one of five experimental diets containing .79% apparently digestible lysine. The first four diets contained 0, .075, .150, and .225% L-lysine x HCl replacing the intact lysine, primarily derived from soybean meal. Dietary crude protein was reduced from 17.9 to 16.9, 15.8, and 14.8% respectively. The fifth diet contained .174% L-lysine x HCl (15.5% CP) with added synthetic methionine, threonine, and tryptophan to restore the ratios of these amino acids to lysine to those in the control diet with no synthetic amino acids. The average lactation length was 15.7 +/- .3 d. Diet did not affect ADFI, sow backfat loss, sow loin eye area loss, or weaning-to-mating interval. Sows consumed an average of 4.6 kg/d and were provided 36 g/d of digestible lysine. Replacing soybean meal with increasing levels of L-lysine x HCl did not affect sow weight change. The number of pigs weaned decreased and preweaning mortality increased linearly (P = .08) with increasing levels of L-lysine x HCl. Litters from sows fed the .174% L-lysine x HCl with added methionine, threonine, and tryptophan grew slower and had a higher mortality rate than litters from sows fed no synthetic amino acids (P < .05). The addition of synthetic methionine, threonine, and tryptophan to the .174% L-lysine x HCl diet did not improve litter growth rate, but it did increase preweaning mortality (P = .05) and decrease the number of pigs weaned (P = .06) compared to the .15% L-lysine x HCl with no additional synthetic amino acids. These additions also resulted in an increased sow weight loss (P = .10). These results suggest that when more than .075% L-lysine x HCl is used to meet the lysine requirement preweaning mortality is increased and the number of pigs weaned is decreased. Supplementation with methionine, threonine, and tryptophan failed to ameliorate the negative response associated with L-lysine x HCl, which suggests that other amino acids may be limiting.

The lysine requirement of lactating primiparous sows.

We conducted an experiment with 289 primiparous sows to evaluate the effect of lysine intake on lactation and subsequent reproductive performance. Sows were randomly allotted to one of five experimental corn-soybean meal lactation diets. The first four diets contained incremental levels of apparently digestible lysine (.67, .86, 1.06, and 1.25%) and provided digestible lysine intakes of 27, 34, 41, and 48 g/d. All lysine was derived from intact protein sources. Synthetic valine, threonine, and methionine were used to maintain ratios to lysine that were equal to those of the .67% lysine diet. The fifth diet contained 1.06% digestible lysine and provided 43 g/d digestible lysine, but no additional synthetic amino acids were added. The average lactation length in this study was 16.9 +/- .2 d. Lysine intake during lactation did not affect number of pigs weaned, litter growth rate, sow backfat loss, or weaning to mating interval. Sow weight loss and loin eye area loss decreased quadratically (P < .05) with increasing lysine intake. These were minimized at 45 and 48 g/d digestible lysine, respectively. Removing synthetic amino acids from the 1.06% digestible lysine diet resulted in an increased litter growth rate (1.98 vs 2.15 kg/d, P < .05). Increasing dietary lysine intake while maintaining amino acid ratios to lysine for valine, threonine, and total sulfur amino acids during the first lactation resulted in a linear (P < .05) decrease in second litter total born. However, removal of synthetic amino acids from the 1.06% digestible lysine diet resulted in an increased second litter total born (12.9 vs 11.2, P < .05), which tended to be higher compared with the .67% digestible lysine treatment (12.9 vs 11.7, P = .13). The results suggest that primiparous sows are able to mobilize sufficient body reserves to maintain a high level of milk production at low levels of lysine intake during a 17-d lactation. Higher levels (45 to 48 g/d) of digestible lysine are required to minimize body protein loss. The source or composition of amino acids in the lactation diet may have an effect on second litter size.

The role of intergenerational discrepancy of cultural orientation in drug use among Latina adolescents.

The role of intergenerational discrepancy for cultural orientation was examined in the etiology of drug use among Latina adolescents and in the context of family support. Intergenerational discrepancy occurs when a family member of one generation differs from a family member of another generation in cultural identity factors; this is usually manifested in conflict between a first generation child and the immigrant generation parent. It was hypothesized that the Latina adolescents experiencing intergenerational discrepancy might use drugs more frequently than Latina adolescents who were not; and that family support would be an important moderator of the relationship. A sample of 295 ninth and tenth grade Latina students (approximately 80% Mexican-American) from four Los Angeles area schools were surveyed as part of a larger study. In this secondary analysis, a 2 (family support ) x 2 (discrepancy) ANOVA revealed that intergenerational discrepancy was associated with more drug use in certain cases, and that family support did not moderate this relationship. Results partially validate and extend a theoretical model presented by Szapocznik and Kurtines (1980), and indicate a need to focus on cultural variables when intervening in drug use/misuse among Latina adolescents.

Concurrent versus simultaneous polydrug use: prevalence, correlates, discriminant validity, and prospective effects on health outcomes.

Few studies have addressed the distinction between concurrent polydrug use (various drugs used on separate occasions) and simultaneous polydrug use (the use of more than 1 drug at the same time). The authors assessed simultaneous polydrug use in a community sample to examine the prevalence of drug combinations, whether simultaneous can be distinguished from concurrent, and the prospective effects of these styles of drug use on subsequent health service utilization, physical symptoms, and psychological distress 4 years later. Marijuana and alcohol were the most common drugs used simultaneously, followed by alcohol and cigarettes. Simultaneous and Concurrent Polydrug Use formed 2 correlated but discriminable constructs. Neither Simultaneous nor Concurrent Polydrug use predicted subsequent Health Service Utilization, Physical Symptoms, or Psychological Distress. Data did reveal unique effects of specific drugs used simultaneously on these outcomes that were larger and more numerous than specific effects of concurrent drug use.

Two varieties of helping in drunk-driving intervention: personal and situational factors.

OBJECTIVE: This study examined personal characteristics and contextual factors among college students who had made an attempt to prevent someone from driving drunk. The study was guided by findings from prior research and the arousal/cost-benefit model of helping. Both passive and assertive interventions and their efficacy were considered. METHOD: Questionnaire data were obtained from 388 students: 206 (68%) had intervened in a DUI situation (63% women). Self-reports of the person (e.g., moral obligation), the situation (e.g., perceived danger) and the type (passive, assertive) and success of the interventions were gathered. RESULTS: Of all interventions used 73% were successful; the median number of interventions used was three. Of the assertive interventions used in DUI situations 57% were successful compared to 47% of the passive interventions. Path analyses revealed that being older relative to the intervenee and greater sobriety of the intervenor predicted more interventions of both types. Personal commitment to intervention, amount of perceived danger and less alcohol consumption increased assertive interventions, whereas talking with someone about the potential DUI person increased the number of passive interventions. The success of both passive and assertive interventions were dependent upon the number of each of these interventions used. However, the more passive interventions were attempted, the less likely the success of an assertive intervention. CONCLUSIONS: The current findings extend our understanding of the psychosocial factors associated with informal DUI intervention, particularly concerning the choice and success of passive versus assertive interventions. Several of these significant predictors support laboratory research findings on helping and the arousal/cost-benefit model, while others do not.
