Drug prevention in a community setting: A longitudinal study of the relative effectiveness of a three-year primary prevention program in boys & girls clubs across the nation

Tested the effectiveness of a youth drug prevention program in a community setting. Boys & Girls Clubs of America's Stay SMART program, adapted from a school-based personal and social competence drug prevention program, was offered, with and without a 2-year booster program, to 13-year-old members of Boys & Girls Clubs. Over 27 months, (a) 5 Boys & Girls Clubs offered the Stay SMART program, (b) 5 Boys & Girls Clubs offered the Stay SMART program with the booster programs, and (c) 4 Boys & Girls Clubs served as a control group. The Stay SMART program alone and the Stay SMART program with the booster programs showed effects for marijuana-related behavior, cigarette-related behavior, alcohol-related behavior, overall drug-related behavior, and knowledge concerning drug use. The Stay SMART program with the booster programs produced additional effects for alcohol attitudes and marijuana attitudes after each year of booster programs. Results suggest that a school-based personal and social competence program can be adapted effectively to a community setting and that booster programs might enhance program effects. Implications for alternative community models of prevention are discussed. At the time of the study, the parent organization was Boys Clubs of America.This research was supported by a grant from the Office for Substance Abuse Prevention, ADAMHA, Public Health Service, Department of Health and Human Services, Grant No. 1 H84 AD 00903-01.     

Flexibility and sharing of childcare duties in black families

With the increasing number of Black mothers participating in the labor force, rearing children without fathers present, and relying on extended family for support the question of the nature of role-flexibility and sharing in the family is raised. Sixty-four families participated in an examination of the relative influence of one- and two-parent Black families and the proximity of the grandmother on self-report measures of (a) household maintenance duties, (b) childcare duties, and (c) parental punishment behaviors. Parents, grandmothers, and at least one child between the ages of 7 and 14 years completed three types of self-report measures. Although the results indicated that mothers, fathers, and grandmothers were nominated as consistently participating in childcare and household maintenance duties, mothers were nominated for more than 60% of the childcare and household tasks. Moreover mothers and not fathers used the full range of discipline practices including corporal punishment. The hypothesis regarding role-sharing in Black household was not supported. Black mothers, like mothers in general, are primarily responsible for the maintenance of the house and the care of children.The preparation of this review was supported by Carter G.

THE EFFECTS OF TOKEN REINFORCEMENT ON THE BEHAVIOR OF DELINQUENTS IN COTTAGE SETTINGS1

A token economy designed to modify the behavior of 125 adolescent males committed to a state correctional institution was implemented in the boys' cottages, focusing on social behavior (peer interaction), rule following, and task completion. The program was sequentially introduced in a multiple-baseline design in three independent cottages; a fourth group served as a comparison cottage. Appropriate behavior increased when the token program was introduced in each cottage. Data were collected for 14 months. Thus, the long-term effects of initial behavior change were assessed.     

Specificity in contrast effects: Judgments of psychopathology

Three experiments were conducted to explore the specificity of the contrast effect in judgments of psychopathology. In the first two studies, respondents initially attempted to infer whether each item in a series of behavior samples (vocabulary definitions in one study, handwriting samples in the second) came from a schizophrenic or a nonschizophrenic patient. Some respondents were presented with highly pathological samples in this induction series, while others were presented with relatively nonpathological samples. These divergent experiences led to marked contrast effects in evaluating test stimuli from the same behavioral domain (e.g., additional vocabulary definitions), but had significantly less impact on the respondent's reactions to stimuli from a different domain (e.g., handwriting samples). A third experiment yielded similar results, using a paired-comparison methodology. In this study subjects first judged a series of high- vs low-pathology definitions. They were then presented with a series of matched stimulus pairs, each including one vocabulary definition and one hand-writing sample. Respondents were to indicate the member of each pair that seemed more indicative of schizophrenia. People assigned to the high-pathology induction group typically chose the handwriting samples as being more indicative of schizophrenia, compared with respondents who were assigned to the low-pathology conditions. These results were interpreted as supporting a representational (perceptual) theory of contrast.     

Applications of the PLATO computer system to research in social psychology

The use of the PLATO CAI system in psychological research is discussed. This discussion covers the use of the PLATO system for research in personal space, attribution, person perception, and group decision making. The aspects of the PLATO system that facilitate research in each of these topic areas are discussed in detail. Further modifications of the PLATO system that would enhance its applicability to psychological research are also discussed.     

Maximizing the validity of a unit-weight composite as a function of relative component lengths with a fixed total testing time

An explicit solution is given to the problem of assigning relative lengths to the subtests of a test so as to maximize the correlation of the unit weight composite with a specified criterion when the total testing time is fixed. This solution is valid and unique whenever it specifies nonnegative times for all variables. A step-down procedure is suggested for cases in which some of the testing times are zero. This procedure does not necessarily provide an optimal allocation. However in examples studied it is found to provide near optimum results. Algorithms are also developed for the determination of the least total testing time required to attain specified multiple and composite correlations. A numerical example is given illustrating the use of the unit weight procedure in combination with the regression weight algorithm.

Coefficient alpha and the reliability of composite measurements

Following a general approach due to Guttman, coefficientα is rederived as a lower bound on the reliability of a test. A necessary and sufficient condition under which equality is attained in this inequality and hence thatα is equal to the reliability of the test is derived and shown to be closely related to the recent redefinition of the concept of parallel measurements due to Novick. This condition is then also shown to be closely related to the unit rank assumption originally adopted by Kuder and Richardson in the derivation of their formula 20. The assumption later adopted by Jackson and Ferguson and the one adopted by Gulliksen are shown to be related to the necessary and sufficient condition derived here. It is then pointed out that the statement that “coefficientα is equal to the mean of the split-half reliabilities” is true only under the restricted condition assumed by Cronbach in the body of his derivation of this result. Finally some limitations on the uses of any function ofα as a measure of internal consistency are noted.     

The stability and control of conditioned noise aversion in the tilt cage

Twenty-six rats were used to study the development of stable conditioned responding to terminate white noise (100 or 105 db) in a tilt cage apparatus. Preliminary work, with one end of the cage consistently associated with silence, demonstrated stability at a high level of cumulative noise-off time per session. Time spent at the noise-off cage end was unaffected by lay-off and showed adaptation to reversal of the cage end functions. Variability in reversal acquisition, insensitivity to stimulus intensity changes and persistence in remaining at one end of the cage in the absence of noise-termination contingencies indicated the need for more precise behavioral control. A schedule programming several reversals of the no-noise end at variable intervals within each session was developed. Performance on the latter schedule was characterized by stability of high noise-off times and also proved more sensitive than the preliminary method to stimulus intensity changes (55, 70, 100 db) as measured by both cumulated noise-off time and cage crossing rates. The ease of training combined with sensitivity to stimulus change and the lack of highly specific motor response requirements make this technique promising for use with animals potentially debilitated by drugs or surgical after-effects.     

Assessing the Current Validity of the Bem Sex-Role Inventory

The Bem Sex-Role Inventory (BSRI) is a widelyused instrument in measuring gender role perceptions.Recent concerns regarding the validity of the adjectiveshave arisen as changes in the roles of men and women have occurred in American society sincethe 1970's. A partial replication of the method that Bem(1974) used to validate the masculine and feminineadjectives comprising the instrument was conducted. All but two of the adjectives were validatedusing Bem's criteria. These findings suggest that theBSRI may still be a valid instrument for assessing genderroles. However, evidence was revealed that traditional masculine and feminine gender role perceptionsmay be weakening. Future validation of the BSRI iswarranted in light of these patterns.
