Use of Repeated Within-Subject Measures to Assess Infants' Preference for Similar Others.

Research employing single-choice paradigms in which an infant is asked to make a single choice between two puppets suggest that infants show a preference for prosocial others and those who are similar to themselves. However, the extent to which infants' preference for similar others is stable is unknown, as are other factors within the paradigm that may influence infants' choices. The purpose of this study (two experiments, = 44 infants, aged 8-15 months) was to replicate and extend previous work by including (1) within-subject repeated measures and (2) an experimental manipulation of a plausible demand characteristic.

Incentivizing physical activity using token reinforcement with preschool children.

We combined several single-subject designs to assess the effects of contingent and noncontingent token reinforcement on moderate-to-vigorous physical activity (MVPA) exhibited by 4 preschool-aged children. Higher overall levels and longer bouts of MVPA reliably occurred when tokens were delivered contingent on MVPA for 3 of the 4 children when compared to baseline (no token) and for 2 of the 4 children when compared to noncontingent-token conditions. The present study demonstrated that the delivery of tokens contingent on MVPA can increase and maintain MVPA exhibited by preschool-aged children, resulting in more MVPA than in baseline conditions and conditions in which tokens are awarded without respect to MVPA.

Pour Convergence: College Students' Definitions and Free-Poured Volumes of Standard Alcohol Servings.

We examined the correspondence between college students' ( N = 192, 71% women) definitions of free-pours and their free-poured volumes of beer, wine, and liquor. Participants' mean beer definitions and free-pours were positively correlated; participants' mean wine and liquor definitions were larger than their free-pours, which were fairly accurate. Contrary to what the aggregate mean values indicated, fewer than half of the participants accurately free-poured a standard volume of beer, wine, or liquor (37.

Stability of infants' preference for prosocial others: Implications for research based on single-choice paradigms.

Some research suggests infants display a tendency to judge others' prosocial behavior, and in particular, that infants show a strong preference for prosocial others. For example, data from one frequently cited and well-publicized study showed that, after watching a puppet show with three puppets, 74% of infants chose the puppet that "helped" rather than the puppet that "hindered" a third puppet from attaining its goal. The purpose of the current investigation was to replicate these methods and extend them by including a within-subject measure of infant puppet choice across repeated trials to assess the stability of infants' choice.

A systematic review of the free-pour assessment: Implications for research, assessment and intervention.

Excessive alcohol consumption is a major concern. Alcohol consumption data are typically collected via self-report questionnaires. However, research has suggested that individuals are unable to identify a standard drink size and that their self-report may be influenced by certain environmental conditions, calling into question the reliability and validity of self-report.

College students' use of energy drinks, social problem-solving, and academic performance.

Energy drink (ED) use among college students to improve academic performance (AP) has skyrocketed. A growing body of literature indicates that the risks associated with ED use may outweigh the perceived benefits. In this study, 486 undergraduates were surveyed on their general substance and ED usage, Social Problem-Solving (SPS) ability, and AP.

Don'T wag the dog: extending the reach of applied behavior analysis.

We argue that the field of behavior analysis would be best served if behavior analysts worked to extend the reach of behavioral services into a more diverse range of settings and with more varied populations, with an emphasis on the establishment of new career opportunities for graduating students. This is not a new proposal, but it is a tall order; it is not difficult to see why many would choose a surer route to gainful employment. Currently, the most fruitful career path for behavior analysts in practice is in the area of autism and developmental disabilities.

The influence of uncertainty and social support on information seeking concerning illicit stimulant use among young adults.

Using the Theory of Motivated Information Management (TMIM) and the concept of desired informational support as a framework, this project examined factors in the information management process young adults employ in potential information seeking about illicit stimulant drug use with members of their social networks. One hundred and seventy-three individuals participated in the study. Results indicated that (a) uncertainty discrepancy and the desire for informational support covaried, and (b) uncertainty discrepancy, anxiety, and outcome expectancy had significant impacts on the efficacy judgments made by individuals with regard to potential information seeking with their social networks about their stimulant drug use.

Brief report: a comparison of indirect versus experimental strategies for the assessment of pica.

We conducted functional analyses of pica for three individuals with varying levels of intellectual disabilities. In addition, two indirect assessment instruments (the Motivational Assessment Scale [MAS], and the Questions About Behavioral Function [QABF]) were also administered to both the parent and teacher of the child participants. Results of the functional analyses indicated that pica was sensitive to automatic reinforcement.

Self-initiated tobacco cessation and substance use outcomes among adolescents entering substance use treatment in a managed care organization.

Purpose: Adolescents with substance use (SU) problems have high rates of tobacco use, yet SU treatment has historically ignored treatment for tobacco use. Barriers to such efforts include the belief that tobacco cessation could compromise other SU abstinence. This study examines self-initiated tobacco cessation and 12-month alcohol and drug abstinence in adolescents entering SU treatment in a private, managed care organization.

Cigarette smoking and long-term alcohol and drug treatment outcomes: a telephone follow-up at five years.

This prospective study examined the relationship between cigarette smoking and five-year substance abuse treatment outcomes. Of 749 individuals who began private outpatient treatment, 598 (80%) were re-interviewed by telephone at five years. At five-year follow-up, 53% reported smoking cigarettes in the prior 30 days.

Pathways to chemical dependency treatment for adolescents in an HMO.

This study examines pathways to chemical dependency (CD) treatment for adolescents in a prepaid health plan, including factors influencing treatment referral and access. Data were collected from 419 adolescent CD treatment intakes ages 13 to 18 in a large, private health plan. The study examines predictors of referral from different sources and of mental health treatment prior to CD treatment.

Adolescents with substance diagnoses in an HMO: factors associated with medical provider referrals to substance abuse and mental health treatment.

This study examines the factors related to referrals of adolescents with substance use disorders to substance abuse or mental health treatment by their medical providers. Administrative and chart review data from the membership of a large private health maintenance organization (HMO) were collected from a probability sample of 400 adolescents, ages 13-18, who were diagnosed with a substance use disorder in 1999. Logistic regression analyses examined referral to substance abuse treatment and referral to mental health treatment in the aggregate and stratified by gender.

Demographic, psychosocial, and personality characteristics of lesbian batterers.

Prevalence of domestic violence (DV) in lesbian and heterosexual relationships appears to be similar. Despite this, few studies have examined factors associated with DV in lesbian relationships, and even fewer have examined characteristics of lesbian batterers. Demographic and psychosocial characteristics and personality traits were examined in 100 lesbians in current relationships (33 Batterers and 67 Nonbatterers).

Couples therapy at end of life.

This study reports on a preliminary uncontrolled study of a treatment for couples in which one partner is diagnosed with a terminal illness. In this study nine couples, in which one partner was diagnosed with a terminal illness and had less than 18 months to live, were offered eight sessions of couples therapy. Follow-up data were available for six couples.

Changes in smoking status among substance abusers: baseline characteristics and abstinence from alcohol and drugs at 12-month follow-up.

The impact of change in smoking status on 12-month substance abuse (SA) treatment outcomes was examined among an HMO population seeking SA treatment. Of the 749 participants who entered the study at baseline, 649 (86.9%) were retained at the 12-month follow-up.

Coping among individuals seeking private chemical dependence treatment: gender differences and impact on length of stay in treatment.

Background: Length of stay in treatment and coping skills are both predictive of chemical dependence and abuse treatment outcomes. However, little is known about whether coping strategies are related to length of stay in treatment. Because predictors of length of stay in treatment vary by gender, it also may be reasonable to expect gender differences in coping strategies as well as in the relationship between coping and LOS in treatment.
