Condom use as a dependent variable: measurement issues relevant to HIV prevention programs

The value of condoms in efforts to slow the spread of HIV infection has been well established in the literature. Behavioral science faces the challenge of promoting condom use through intervention programs. As these programs are evaluated, multiple issues should be considered in relation to measuring participant use of condoms for the purposes of preventing HIV infection. Lack of attention to these issues is likely to create a large number of Type I and Type II errors. Ten common sources of error are described and corresponding recommendations for eliminating these errors are offered. A review of published studies shows that there is little consistency relevant to controlling for these sources of error. Incorporation of standardized methodology will allow for more accurate program evaluation and benefit researchers by facilitating comparisons across studies.     

Connecting the dots: Children's use of a systematic figure to facilitate mapping and search.

Organizing locations into a systematic figure was predicted to facilitate children's use of spatial relations in a mapping task. In Study 1, 3-, 4-, and 5-year-olds used a map to find a sticker hidden under 1 of 27 locations. The search locations formed a systematic figure, the outline of a dog. Half of the children were shown that the locations formed a dog. Seeing the dog pattern facilitated the performance of 5-year-olds but not that of the younger children. Study 2 indicated that children had to see a systematic figure to gain an advantage; adding lines to an unsystematic figure did not convey an advantage. Study 3 indicated that a verbal label alone could not convey an advantage. Study 4 revealed that seeing the dog pattern could also facilitate performance when the map was rotated relative to the represented space. The importance of organizing spatial information to facilitate relational thinking and mapping is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The use of acceptance and commitment therapy to prevent the rehospitalization of psychotic patients: A randomized controlled trial.

The present study examined the impact of a brief version of an acceptance-based treatment (acceptance and commitment therapy; ACT) that teaches patients to accept unavoidable private events; to identify and focus on actions directed toward valued goals; and to defuse from odd cognition, just noticing thoughts rather than treating them as either true or false. Eighty inpatient participants with positive psychotic symptoms were randomly assigned to treatment as usual (TAU) or to 4 sessions of ACT plus TAU. ACT participants showed significantly higher symptom reporting and lower symptom believability and a rate of rehospitalization half that of TAU participants over a 4-month follow-up period. The same basic pattern of results was seen with all participant subgroups except delusional participants who denied symptoms. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Building a model for prevention practice: Depression as an example.

Preventing mental illness has become increasingly emphasized as a priority for psychologists. Unfortunately, clinicians who want to incorporate prevention activities into their practice have few available models to guide how they might accomplish such a task. Using the literature on the prevention of depression, the authors make specific recommendations to clinicians who are interested in expanding their practice by offering preventive interventions in addition to their usual treatment activities. Topics discussed include choosing target populations for the intervention, using a theoretical orientation to guide the intervention, selecting specific ingredients to include in the intervention, deciding among different intervention modalities, and obtaining financial reimbursement for prevention work. Prevention work can be a novel solution to help meet the unsatisfied needs of patients, clinicians, and society. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Correlates of unhealthy weight-control behaviors among adolescents: Implications for prevention programs.

This study aimed to identify correlates of unhealthy weight-control behaviors in adolescents to guide the development of programs aimed at the primary prevention of disordered eating. A model explaining unhealthy weight-control behaviors was tested among 4,746 adolescents using structural equation modeling. Models fit the data well and explained 76% of the variance in unhealthy weight-control behaviors among girls and 63% among boys. Weight-body concerns were a strong correlate of unhealthy weight-control behaviors in both girls and boys. Models also emphasized the importance of weight-specific social norms within the adolescent's proximal environment. Findings suggest the importance of addressing weight-body concerns within prevention programs and extending interventions beyond classroom settings to ensure changes in weight-related norms among peer groups and family members.

A community-oriented evaluation of two prevention programs for college freshmen.

Evaluated 2 preventive interventions aimed at reducing the stress of the 1st yr of college for freshmen; 3,713 Ss were used. The cohort program, a written-interactive program, was compared to a peer-led group program both for their possible impact on the college freshman population on a variety of measures available in the campus community and for their effectiveness as treatments on traditional questionnaire measures. The programs were found to differ in the type of students they attracted, with the cohort program attracting more nonusers of traditional services and the group program attracting those who would otherwise use traditional services. While both the programs were seen as effective by their respective participants, neither treatment was effective in reducing dropout rate or improving GPA. Results are discussed both in terms of the treatment impact on the individuals participating and in terms of program impact on freshman population experiencing psychological stress in their 1st yr of school.

Practice makes perfect? The role of participant modeling in sexual abuse prevention programs.

We tested the prediction that a sexual abuse prevention program that included participant modeling (PM) would result in superior skill acquisition compared with a symbolic modeling (SM) program. Twenty-six kindergarten children were assigned to one of the two programs after being matched for initial skill level. The PM program taught self-protective skills through modeling and active rehearsal; the SM program taught the same skills, but the children watched as skills were modeled by the experimenter. Results provided evidence for the greater efficacy of PM relative to SM for the learning of personal safety skills and, thus, support the inclusion of active rehearsal in prevention programs for young children.

Health promotion, wellness programs, quality of life and the marketing of psychology.

This paper focusses on 15 yrs of research into the definition of quality of life and the factors that influence it. Four studies with 3 samples of 780 residents of London, Ontario, are presented. Results suggest (1) that different measures of global quality of life and well being are measuring essentially the same thing; (2) that there may be some basis for viewing the mental health component measure on the SF-36 Health Survey as highly indicative of quality of life; and (3) that important psychological factors contributing to health and quality of life include such personality factors as hardiness, self-esteem, optimism, locus of control, and extraversion. The application of the research to health promotion and the development of wellness programs is discussed. A strategy to enhance quality of life using the Quality of Life Questionnaire, and group interventions to enhance specific personality characteristics are described. The current research program is used as a case study to demonstrate some of the factors that contribute to the invisibility of psychology.

Dissonance and healthy weight eating disorder prevention programs: A randomized efficacy trial.

In this trial, adolescent girls with body dissatisfaction (N = 481, M age = 17 years) were randomized to an eating disorder prevention program involving dissonance-inducing activities that reduce thin-ideal internalization, a prevention program promoting healthy weight management, an expressive writing control condition, or an assessment-only control condition. Dissonance participants showed significantly greater reductions in eating disorder risk factors and bulimic symptoms than healthy weight, expressive writing, and assessment-only participants, and healthy weight participants showed significantly greater reductions in risk factors and symptoms than expressive writing and assessment-only participants from pretest to posttest. Although these effects faded over 6-month and 12-month follow-ups, dissonance and healthy weight participants showed significantly lower binge eating and obesity onset and reduced service utilization through 12-month follow-up, suggesting that both interventions have public health potential.

The use and acceptance of social science evidence in business litigation after Daubert.

The landmark U.S. Supreme Court case of Daubert v. Merrell Dow Pharmaceuticals , which overturned the venerable Frye test for the admissibility of scientific evidence, has sparked considerable interest among scholars and practitioners, within both the law and the various sciences. The discussion of the impact of Daubert on social science evidence, however, has been largely confined to a narrow range of issues, primarily concerning criminal law and mental health. Indeed, the Daubert case thus far has received relatively scant attention in the published cases involving business litigation, and in most of these instances, the focus has been on evidence from the hard sciences rather than from the social sciences. The author explores the use and acceptance of social science evidence in business litigation within the post- Daubert era. First, the specific Daubert factors are analyzed from the perspective of social science evidence in business litigation. Second, the scope of business litigation which has been impacted-or which is potentially impacted-by Daubert is outlined and discussed. Third, various procedural issues in the post- Daubert era are explored, including motions for summary judgment to dispose of social science issues… (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The ecological effects of universal and selective violence prevention programs for middle school students: A randomized trial.

This study reports the findings of a multisite randomized trial evaluating the separate and combined effects of 2 school-based approaches to reduce violence among early adolescents. A total of 37 schools at 4 sites were randomized to 4 conditions: (1) a universal intervention that involved implementing a student curriculum and teacher training with 6th-grade students and teachers, (2) a selective intervention in which a family intervention was implemented with a subset of 6th-grade students exhibiting high levels of aggression and social influence, (3) a combined intervention condition, and (4) a no-intervention control condition. Analyses of multiple waves of data from 2 cohorts of students at each school (N = 5,581) within the grade targeted by the interventions revealed a complex pattern. There was some evidence to suggest that the universal intervention was associated with increases in aggression and reductions in victimization; however, these effects were moderated by preintervention risk. In contrast, the selective intervention was associated with decreases in aggression but no changes in victimization. These findings have important implications for efforts to develop effective violence prevention programs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A meta-analytic review of obesity prevention programs for children and adolescents: The skinny on interventions that work.

This meta-analytic review summarizes obesity prevention programs and their effects and investigates participant, intervention, delivery, and design features associated with larger effects. A literature search identified 64 prevention programs seeking to produce weight gain prevention effects, of which 21% produced significant prevention effects that were typically pre- to post effects. Larger effects emerged for programs that targeted children and adolescents (vs. preadolescents) and females, programs that were relatively brief, programs that solely targeted weight control versus other health behaviors (e.g., smoking), programs evaluated in pilot trials, and programs wherein participants must have self-selected into the intervention. Other factors, including mandated improvements in diet and exercise, sedentary behavior reduction, delivery by trained interventionists, and parental involvement, were not associated with significantly larger effects.

The relationship of family structure to adolescent drug use, peer affiliation, and perception of peer acceptance of drug use

This study examined the relationship of family structure to adolescent gateway drug use and peer-related factors. The sample consisted of 2,121 randomly selected students in grades 8, 10, and 12 from seventeen school districts in northeastern Ohio. Students were administered a self-report instrument containing items measuring drug use and psychosocial variables. For purposes of analysis, the dependent variables included frequency of use of five gateway drugs, degree of affiliation with drug-using peers, and perceptions of peer acceptance of drug use. Comparison groups included single-parent (both mother- and father-headed), stepparent, and intact families. Analyses were conducted separately by grade level. Significant differences were found between groups on the drug-use variables at grades 8 and 10, with adolescents from intact families reporting less frequent drug use, fewer drug-using friends, and perceptions of more peer disapproval of drug use. Interestingly, there were several statistically significant group differences on perceptions of peer acceptance of drug use and the number of drug-using friends at the 8th-grade level. The largest differences were found between the single-parent (father-headed) and intact groups, with adolescents from father-headed families showing more frequent beer and liquor consumption at the 10th-grade level.     

Evaluating process in child and family interventions: Aggression prevention as an example.

This article reports on 2 studies designed to develop and validate a set of measures for use in evaluating processes of child and family interventions. In Study 1 responses from 187 families attending an outpatient clinic for child behavior problems were factor analyzed to identify scales, consistent across sources: Alliance (Satisfactory Relationship with Interventionist and Program Satisfaction), Parenting Skill Attainment, Child Cooperation During Session, Child Prosocial Behavior, and Child Aggressive Behavior. Study 2 focused on patterns of scale scores among 78 families taking part in a 22-week preventive intervention designed to affect family relationships, parenting, and child antisocial and prosocial behaviors. The factor structure identified in Study 1 was replicated. Scale construct validity was demonstrated through across-source convergence, sensitivity to intervention change, and ability to discriminate individual differences. Path analysis validated the scales' utility in explaining key aspects of the intervention process. Implications for evaluating processes in family interventions are discussed.

The prevention of mental health problems in Canada: A survey of provincial policies, structures, and programs.

The purpose of this research was to obtain a profile of the state of prevention in mental health in Canada. In all the provinces and territories, we obtained information from the departments of children's mental health, adult mental health, and health promotion regarding administrative supports, personnel, policies, budgets, inter-ministerial collaboration, training, and programs allocated for prevention. The findings indicate that the rhetoric of prevention is present in many government policy documents and there are many interesting prevention projects that have been implemented. However, there has not been a reallocation of funding in the health field from treatment and rehabilitation services to prevention programs, and funding for prevention remains at a very low level. Recommendations to improve the state of prevention are made. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Young women's condom use: The influence of acceptance of sexuality, control over the sexual encounter, and perceived susceptibility to common STDs.

A comprehensive model of the determinants of condom use among young women was developed, tested, and replicated, with longitudinal follow-up to assess predictive utility of the model for condom use over time. Participants in Study 1 and Study 2 were 198 female undergraduates (mean age, 18.6 years) and 238 female undergraduates (mean age, 19.1 years), respectively. Acceptance of sexuality and control over the sexual encounter were related to a multidimensional measure of condom use self-efficacy, which predicted condom use intentions. Perceived susceptibility to STDs was both directly related to intentions and indirectly related through perceived benefits and attitudes about condom use. Intentions predicted subsequent reports of condom use. The model suggests foci for condom use interventions for young women. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Parents and children: Legal reform to facilitate children's participation.

The mandate in the law and ethics of human rights to take children seriously as people usually should not be framed as deference to parents or children. Rather, careful efforts to promote the participation of children--to help them to feel that they are heard--will usually bring parents (and other adults) and children together in shared decision making. Such recognition reframes the core problem of children's law to be the creation of structures to facilitate such intergenerational involvement, not the choice of the age at which children's decisions should be recognized as authoritative.

The application of psychodidactic support groups to facilitate female offenders' adjustment to prison.

Describes a program designed to facilitate newly admitted female inmates' adjustment to prison. More than 95% of the first offenders and 60% of the recidivists who were invited to join this program at the North Carolina Correctional Center for Women agreed to participate. The goals of the psychodidactic program were to promote a supportive group atmosphere, to convey relevant information, and to help group members to relate that information to their personal and collective experiences. Self-report measures indicate that participants experienced themselves as better-adjusted and more accepting of their circumstances than nonparticipants.

Screening for disruptive behavior syndromes in children: The application of latent class analyses and implications for prevention programs.

The predictive accuracy of classifying children at risk for disruptive disorders through latent class analyses (LCA) was evaluated. Child Behavior Checklist/4-18 (T. M. Achenbach, 1991) items, reflecting symptoms of Diagnostic and Statistical Manual of Mental Disorders (4th ed., American Psychiatric Association, 1994) defined disruptive disorders, alone and in combination with other child and familial risk factors, were used to predict children's risk for disruptive disorder. Predictive accuracy reached a positive predictive value of 69%. Children incorrectly classified (false positive and false negative) were compared with correctly classified children (true positive and true negative) on risk factors in the family context to test whether the screening procedure could be improved through a multiple-gating procedure. The differences in familial context factors between these children were limited, and no clear indications were found on how to use familial context factors to improve the screening procedure after the initial classification by LCA.
