Concern for appropriateness as a moderator variable in the statistical explanation of self-reported use of alcohol and marijuana

Two studies examine the Concern for Appropriateness Scale (Lennox & Wolfe, 1984) as a likely moderator of dispositional and environmental variables associated with self-reported use of alcohol and marijuana by college and precollege students. In Study 1, data from 408 upper division students show that concern score interacts significantly with religiosity in analyses of use of both drugs, but not with any of 11 other dispositional variables nor with drug-specific environment predictors in analyses of use of either drug. In Study 2, data from 242 recent high school graduates show that concern score interacts significantly with religiosity and drug-specific environment in the explanation of alcohol use but not in the explanation of marijuana use. All of the significant interactions are in the predicted direction. Results therefore suggest that the concern scale is valid for some of its intended purposes.     

Driving after use of alcohol and marijuana in college students.

Driving after use of marijuana is almost as common as driving after use of alcohol in youth (P. M. O'Malley & L. D. Johnston, 2003). The authors compared college students' attitudes, normative beliefs and perceived negative consequences of driving after use of either alcohol or marijuana and tested these cognitive factors as risk factors for substance-related driving. Results indicated that youth perceived driving after marijuana use as more acceptable to peers and the negative consequences as less likely than driving after alcohol use, even after controlling for substance use. Results of zero-inflated Poisson regression analyses indicated that lower perceived dangerousness and greater perceived peer acceptance were associated with increased engagement in, and frequency of, driving after use of either substance. Lower perceived likelihood of negative consequences was associated with increased frequency for those who engage in substance-related driving. These results provide a basis for comparing how youth perceive driving after use of alcohol and marijuana, as well as similarities in the risk factors for driving after use of these substances.     

Stress-response-dampening effects of alcohol: attention as a mediator and moderator

The present study sought to characterize alcohol's stress-response-dampening (SRD) effects on multiple measures of stress and whether these effects are mediated by reductions in sustained attention and, further, whether baseline levels of sustained attention moderate SRD. One hundred six men consumed either an alcohol (0.70 g/kg) or a placebo beverage prior to learning that they would deliver a self-disclosing speech. Structural equation models controlling for multiple baseline periods indicated that alcohol directly reduced self-reported anxiety and skin conductance levels in response to the stressor. Alcohol's effect on reducing heart rate response, in contrast, was indirect and mediated by effects on prestress baseline. As hypothesized, differences in sustained attention partially mediated the effects of alcohol on skin conductance (but not heart rate or self-reported anxiety) and served as a moderator of alcohol's effects on skin conductance response. Findings are discussed in terms of theoretical links among alcohol consumption, specific cognitive abilities, and stress reactivity.     

Age as a moderator of the relation between three dimensions of satisfaction and sex role

We examined the moderating effect of age on the relation between sex role orientation and relationship and job satisfaction as well as life satisfaction. Two hundred and thirty-two noncollege married, employed, young, middle, and older adults were administered the Bem Sex Role Inventory, the General Positive Affect Scale, the Minnesota Satisfaction Questionnaire, and the Dyadic Adjustment Scale. Age significantly moderated the relation between each type of sex role and life satisfaction. As age increased, the strength of the relation between sex role and life satisfaction increased. Age also moderated the relation between masculinity and androgyny and job satisfaction, whereas femininity was not significant in predicting job satisfaction. There were no significant predictors of relationship satisfaction.     

Gender differences in the relationship of moderator variables to stress and symptoms

Abstract

This study focused on gender differences in the relationship of four moderator variables (hostility, social support, optimism, and Type A behavior) to perceptions of symptoms and stress based on a sample of 120 female and 79 male undergraduates. Results confirmed significant gender differences in hostility, Type A behavior, and social support but not in optimism. Multiple regression analyses exposed distinct gender differences. For females, social support accounted for 21% and hostility 5% of the total variance in perceived stress. For males, only hostility accounted for any significant variance (10%). Hostility contributed 21% and social support contributed 13% to the total variance in the number of symptoms for females. For males, optimism contributed 14% and hostility 5%. Results indicate that social support is a potent variable for females in their perception of both stress and symptoms but essentially unrelated for males. Hostility, however, relates to perceptions of stress and symptoms for both sexes.     

Parent-peer influence as a predictor of marijuana use.

Although there is some literature which discusses adolescent reference groups, none have utilized reference group theory to examine the relative impact of the parent and peer reference groups and to attempt to predict behavior among teenagers from this knowledge. This study attempts to correct this deficiency by examining the frequency of marijuana use in a nonrandom sample of college students from a large southwestern university. Ordinal type scales and tau-b provide a statistically strong degree of association between the type of reference group orientation and marijuana use. The results of this study show that the influence of the most salient reference group appears to be an important predictor of whether or not an individual may engage in the use of marijuana.     

The protective effects of ethnic identity for alcohol and marijuana use among Black young adults

This study examined the extent to which individual differences in alcohol and marijuana use among 167 Black university students could be accounted for by degree of ethnic identity. After controlling for year in school, sex, and friends' substance use, higher levels of ethnic identity indeed were found to be significantly related to lower beer/hard liquor use, wine use, and marijuana use, accounting for approximately 31%, 6%, and 4% of the variance, respectively. For marijuana use, however, friends' substance use accounted for more of the variance (13%) than did ethnic identity (4%).     

Group commitment as a moderator of attributional and behavioural responses to power use

This study used 50 Natural Science and English Literature students who held differential behavioural expectations of ingroup and outgroup members to investigate evaluative, attributional and behavioural responses to power use in an experimental research paradigm. It was hypothesized that subordinates interpret frequent power use by a superior differently depending on whether it is consistent or inconsistent with previous expectations. Frequent power use results in decreased satisfaction and negative evaluations of the superior. Attributional ratings indicated that when an outgroup member engaged in frequent power use, this negatively evaluated behaviour was attributed to the superior's group membership, and resulted in decreased cooperation on the part of the subordinate. To the extent that frequent power use of an ingroup member was attributed to external circumstances, subordinates maintained a sense of commitment to the ingroup superior, which resulted in displays of cooperative behaviour. © 1998 John Wiley & Sons, Ltd.     

Ethnic differences and the closing of the sex gap in alcohol use among college-bound students.

In this study, the authors used Web-based surveys to examine differences in alcohol use by sex and ethnicity and factors associated with these group differences among 2,241 college-bound students. A Sex x Ethnicity interaction indicated that the sex gap was much larger for Latino than for Caucasian students. Although peer influence was important for both Caucasian and Latino students, family influences were significant only for Latino youths. The sex differences in drinking among Latino youths were largely explained by the combination of same-sex family member and same-sex peer drinking through values about the acceptability of drinking behavior. Among Caucasians, perceptions of peer behavior exerted a stronger influence on drinking behavior than among Latinos. These results suggest that interventions targeting peer influence are likely to be most effective for Caucasian students. In contrast, for Latinos, particularly Latina women, family characteristics may be an important target for prevention.     

Self‐efficacy as a moderator of negative and positive self‐fulfilling prophecy effects: mothers' beliefs and children's alcohol use

This research examined two issues relevant to self‐fulfilling prophecies. First, it examined whether children's risk for alcohol use, as indicated by their self‐efficacy to refuse alcohol from peers, moderated their susceptibility to negative and positive self‐fulfilling prophecy effects created by their mothers. Second, it explored behavioral mediators that could be involved in the self‐fulfilling process between mothers and children. Longitudinal data from 540 mother–child dyads indicated that (1) low self‐efficacy children were more susceptible to their mothers' positive than negative self‐fulfilling effects, whereas high self‐efficacy children's susceptibility did not vary, (2) mothers' global parenting and children's perception of their friends' alcohol use partially mediated mothers' self‐fulfilling effects, and (3) these mediators contributed to low self‐efficacy children's greater susceptibility to positive self‐fulfilling prophecy effects. The power of self‐fulfilling prophecies, their link to social problems, and the potential for mothers' favorable beliefs to have a protective influence on adolescent alcohol use are discussed.

Predicting 13-year-olds' drinking using parents' self-reported alcohol use and restrictiveness compared with offspring's perception

This study examined whether offspring's perception of parental frequency of alcohol use and restrictiveness towards offspring's alcohol use could be used as a substitute for parental self-reports. Offspring's perception were compared with parents' self-reported alcohol use and restrictiveness in ability to predict offspring's own alcohol use. Respondents were 924 offspring, 642 fathers and 729 mothers. Correlations between fathers' and mothers' self-reported frequency of drinking alcohol and offspring's reports of parental frequency of drinking alcohol ranged from 0.55 to 0.70. Fathers' and mothers' self-reported alccohl use and restrictiveness explained less than two per cent of the variance in their offspring's alcohol use in regression analyses, while offspring's perception of parental drinking frequency and restrictiveness exaplained about eight per cent of the variance in offspring's alcohol use. These results represent a challenge to studies of young adolescents which interpret offspring's reports of parents' alcohol use as a surrogate measure 'of parents' self-reported alcohol use.     

Analysis of acculturation, sex, and heavy alcohol use in Latino college students

24% of 917 students at California State University Long Beach who completed an alcohol use survey in 2002 (73% response) identified themselves as Latino. Because measures of acculturation reported in most adult studies positively correlated with alcohol use and sex, it was hypothesized that these associations might also apply to Latino college students. With increasing levels of acculturation, women but not men in this Latino college sample reported significantly greater occurrence of heavy drinking, positive attitudes about drinking, and perception that most of their friends use alcoholic beverages.     

Peer crowds in a commuter college sample: the relation between self-reported alcohol use and perceived peer crowd norms

The author studied peer crowds on a college commuter campus and examined the relation between self-reported alcohol use and perceived peer crowd norms for alcohol use. College students (N = 271) completed questionnaires to determine their peer crowd affiliation and frequency and amount of alcohol use. The author assessed perceived peer-crowd affiliation norms with a series of vignettes describing the typical student that would be associated with each peer crowd. Analyses revealed identifiable peer crowds among college students that represent different patterns of alcohol use both in self-reported alcohol use among students in a peer crowd and in the perceived norms for alcohol use in each peer crowd. The author described the relation between self-reported use and the perceived use by members of one's peer crowd.     

Neuroticism versus demographic variables as correlates of self-reported life satisfaction in a sample of older adults

The Life Satisfaction Index A, State-Trait Anxiety Inventory, and Profile of Mood States were administered to 120 retired Californians whose mean age was 73 yr. Demographic data were also collected. Life satisfaction scores were greater among those respondents with low self-rated anxiety, high religious commitment, higher socio-economic status, and in good health. Trait anxiety alone accounted for approximately 39% of the total variance in self-reported life satisfaction, although further significant contributions were made by state anxiety and religious commitment. It is argued that self-ratings of life satisfaction among older adults are primarily expressions of stable personality attributes, and that further studies of this type should employ standard measures used in describing adjustment in the general population.     

Qualitative and quantitative sex differences in self-reported aggressive behavioral characteristics

Aggressive behavioral characteristics were assessed in a large group of men and women by a self-report instrument, the Aggression Inventory. Significant gender differences appeared on four factors in which men reported more physical aggression and verbal aggression than did women. Further, men had higher scores on measures of impulsiveness and lack of patience than women, while women reported being more likely to avoid confrontation. In addition to these quantitative sex differences in self-reported behavior, factor analyses indicated qualitative differences by sex, wherein most of the variance for women centered on verbal aggression, while physical aggression was the first factor for men.
