Proposed program guidelines for pregnant radiology residents: a project supported by the American Association for Women Radiologists and the Association of Program Directors in Radiology.

RATIONALE AND OBJECTIVES: Written institutional policies governing radiation exposure and work responsibilities for pregnant radiology residents are not uniform and often are nonexistent. Standardized program guidelines would allow residents and program directors alike to prepare for a resident pregnancy with objectivity and consistency. MATERIALS AND METHODS: The American Association for Women Radiologists (AAWR) launched a task force to revisit guidelines for the protection of pregnant residents from radiation exposure during training. We conducted two surveys of the Association of Program Directors in Radiology (APDR) membership. Survey 1 was designed to learn about existing program and institutional policies and to assess the need for and interest in standardized guidelines that would address radiation exposure and work responsibilities for pregnant radiology residents. Based on those responses, we drafted a set of program guidelines incorporating policies contributed by responding program directors. Our follow-up APDR survey, survey 2, was conducted to determine opinions and acceptance of the drafted program guidelines. Each survey was analyzed by using a proportion of means test. RESULTS: Fifty-five of 156 program director APDR members (35%) responded to survey 1. Only half the respondents had formal written policies at their respective institutions. Review of submitted policies showed widely divergent opinions about appropriate policies for pregnant radiology residents. Most (34/52; 75%) supported the development of standardized guidelines. In survey 2, 38/73 responding APDR members (53%) offered their opinions and comments on our drafted guidelines. Approximately 90% agreement was catalogued on 13 of 18 items (72%); a majority (>60%) agreed on all points, even the most controversial points concerning fluoroscopy. CONCLUSION: A minority of radiology residency programs have written policies addressing pregnancy during training. With expressed support from a majority of responding program directors, we have developed and present here proposed program guidelines for pregnant radiology residents to serve as a framework for radiology residents and program directors alike.

Use of program logic models in the Southern Rural Access Program evaluation.

The Southern Rural Access Program (SRAP) evaluation team used program logic models to clarify grantees' activities, objectives, and timelines. This information was used to benchmark data from grantees' progress reports to assess the program's successes. This article presents a brief background on the use of program logic models--essentially charts or diagrams specifying a program's planned activities, objectives, and goals--for evaluating and managing a program. It discusses the structure of the logic models chosen for the SRAP and how the model concept was introduced to the grantees to promote acceptance and use of the models. The article describes how the models helped clarify the program's objectives and helped lead agencies plan and manage the many program initiatives and subcontractors in their states. Models also provided a framework for grantees to report their progress to the National Program Office and evaluators and promoted the evaluators' visibility and acceptance by the grantees. Program logics, however, increased grantees' reporting requirements and demanded substantial time of the evaluators. Program logic models, on balance, proved their merit in the SRAP through their contributions to its management and evaluation and by providing a better understanding of the program's initiatives, successes, and potential impact.

Steps to a HealthierUS Cooperative Agreement Program: foundational elements for program evaluation planning, implementation, and use of findings.

The Steps to a HealthierUS Cooperative Agreement Program (Steps Program) enables funded communities to implement chronic disease prevention and health promotion efforts to reduce the burden of diabetes, obesity, asthma, and related risk factors. At both the national and community levels, investment in surveillance and program evaluation is substantial. Public health practitioners engaged in program evaluation planning often identify desired outcomes, related indicators, and data collection methods but may pay only limited attention to an overarching vision for program evaluation among participating sites. We developed a set of foundational elements to provide a vision of program evaluation that informs the technical decisions made throughout the evaluation process. Given the diversity of activities across the Steps Program and the need for coordination between national- and community-level evaluation efforts, our recommendations to guide program evaluation practice are explicit yet leave room for site-specific context and needs. Staff across the Steps Program must consider these foundational elements to prepare a formal plan for program evaluation. Attention to each element moves the Steps Program closer to well-designed and complementary plans for program evaluation at the national, state, and community levels.

What to expect from a residency program: answers from a directory of residency programs in obstetrics and gynecology.

OBJECTIVE: To answer questions about obstetric-gynecologic resident salary, night call, vacation, outside employment, gender mix, and training experiences using data from a national directory of residency programs in obstetrics and gynecology. METHODS: The 259 US civilian residency programs were analyzed, using information from the 1996 directory database. We compared programs by size (four or fewer residents per year versus more than four residents per year) and geographic region for each of the questions. We used parametric and nonparametric statistical tests to determine statistical significance. RESULTS: First-year residents earn an average of $31,414 annually and receive a 5% increase each year, although salary varies significantly by region. Residents are on call an average of every 3rd night (twice a week) in the 1st year and every 4th or 5th night in the chief year. Residents in small programs take more night call than those in large programs. A separate night call rotation was more common in large programs. Vacation time varied by year of training and region. Male-to-female ratios in training differed significantly by year in training, program size, and region. The median number of training experiences was identified in each of the categories required by the Residency Review Committee in obstetrics and gynecology. Training experiences varied significantly by program size in three of the 15 categories. CONCLUSION: Program size and geographic region should be considered when comparing programs with regard to pay, work, time off, outside employment, gender mix, and training experiences. Program advisors and potential applicants are encouraged to use this information in comparing programs.

The evolution of the State Children's Health Insurance Program (SCHIP) in New York: changing program features and enrollee characteristics.

BACKGROUND: The State Children's Health Insurance Program (SCHIP) has been operating for >5 years. Policy makers are interested in the characteristics of children who have enrolled and changes in the health care needs of enrolled children as programs mature. New York State's SCHIP evolved from a similar statewide health insurance program that was developed in 1991 (Child Health Plus [CHPlus]). Understanding how current SCHIP enrollees differ from early CHPlus enrollees together with how program features changed during the period may shed light on how best to serve the evolving SCHIP population. OBJECTIVE: To 1) describe changes in the characteristics of children enrolled in 1994 CHPlus and 2001 SCHIP; 2) determine if changes in the near-poor, age-eligible population during the time period could account for the evolution of enrollment; and 3) describe changes in the program during the period that could be responsible for the enrollment changes. SETTING: New York State, stratified into 4 regions: New York City, New York City environs, upstate urban counties, and upstate rural counties. DESIGN: Retrospective telephone interviews of parents of 2 cohorts of CHPlus enrollees: 1) children who enrolled in CHPlus in 1993 to 1994 and 2) children who enrolled in New York's SCHIP in 2000 to 2001. The Current Population Survey (CPS) 1992 to 1994 and 1999 to 2001 were used to identify secular trends that could explain differences in the CHPlus and SCHIP enrollees. PROGRAM CHARACTERISTICS: 1994 CHPlus and 2001 SCHIP were similar in design, both limiting eligibility by age, family income, and insurance status. SCHIP 2001 included 1) expansion of eligibility to adolescents 13 to 19 years old; 2) expansion of benefits to include hospitalizations, mental health, and dental benefits; 3) changes in premium contributions; 4) more participating insurance plans, limited to managed care; 5) expansions in marketing and outreach; and 6) a combined enrollment application for SCHIP and several low-income programs including Medicaid. SAMPLE: Cohort 1 included 2126 new CHPlus enrollees 0 to 13 years old who were enrolled for at least 9 months, stratified by geographic region. Cohort 2 included 1100 new SCHIP enrollees 0 to 13 years old who were enrolled for at least 9 months, stratified by geographic region, age, race, and ethnicity. Results were weighted to be representative of statewide CHPlus or SCHIP new enrollees who met the sampling criteria. Samples of age- and income-eligible children from New York State were drawn from the CPS and pooled and reweighted (1992-1994 and 1999-2001) to generate a comparison group of children targeted by CHPlus and SCHIP. MEASURES: Sociodemographic characteristics, race and ethnicity (white non-Hispanic, black non-Hispanic, and Hispanic), prior health insurance, health care access, and first source of information about the program. ANALYSES: Weighted bivariate analyses (comparisons of means and rates) adjusted for the complex sampling design to compare measures between the 2 program cohorts and between the 2 CPS samples. We tested for equivalence by using chi2 statistics. RESULTS: As the program evolved from CHPlus to SCHIP, relatively more black and Hispanic children enrolled (9% to 30% black from 1994 to 2001, and 16% to 48% Hispanic), more New York City residents (46% to 69% from 1994 to 2001), more children with parents who had less than a high school education (10% to 25%), more children from lower income families (59% to 75% below 150% of the federal poverty level), and more children from families with parents not working (7% to 20%) enrolled. These socioeconomic and demographic changes were not reflected in the underlying age- and income-eligible population. A greater proportion of 2001 enrollees were uninsured for some time immediately before enrollment (57% to 76% had an uninsured gap), were insured by Medicaid during the year before enrollment (23% to 48%), and lacked a USC (5% to 14%). Although "word of mouth" was the most common means by which families heard about both programs, a greater proportion of 2001 enrollees learned about SCHIP from marketing or outreach sources. CONCLUSION: As New York programs for the uninsured evolved, more children from minority groups, with lower family incomes and education, and having less baseline access to health care were enrolled. Although changes in the underlying population were relatively small, progressively increased marketing and outreach, particularly in New York City, the introduction of a single application form for SCHIP and Medicaid, and expansions in the benefit package may have accounted, in part, for the large change in the characteristics of enrollees.

Clinicians, the Mount Sinai program and the Veterans' Administration program evaluated against clinico-pathological data derived independently of the electrocardiogram.

221 electrocardiograms (ECGs) recorded from adult subjects with cardiac symptomatology were interpreted by clinicians and the Mount Sinai (MS) and Veterans' Administration (VA) computer programs. After the clinicians had eliminated their interobserver variability, their interpretations and those of the computer programs were compared with the corresponding clinico-pathological data that had been derived independently of the ECG. A measure of overall diagnostic accuracy was used which showed that the performance of the 2 computer programs was similar and somewhat worse than that of the clinicians. The clinicians and the computer programs were not as good at diagnosing the ECGs of women as at diagnosing those of men. As the VA program's interpretations may be altered by including information about the patient's provisional diagnosis, 6 different sets of these prior probabilities were used to analyse 141 of the original 221 ECGs. Different fixed sets of prior probabilities made only a small difference to overall diagnostic accuracy but a marked difference to the VA program's ability to differentiate Normal from Abnormal. Optimizing the prior probabilities for the individual subjects increased the VA program's overall diagnostic accuracy up to that of the clinicians. Both computer programs correctly diagnosed sinus rhythm as the dominant rhythm in 165 out of 177 subjects. The MS program diagnosed the dominant rhythm as Atrial Fibrillation in 35 out of 41 subjects and the VA program in 27 (X(2) = 3.24; not significant).

Diffusion of a school-based substance abuse prevention program: predictors of program implementation.

BACKGROUND: The present study addresses diffusion of a psychosocial-based substance abuse prevention program, including: (a) teacher adoption, implementation, and maintenance; (b) teacher characteristics associated with implementation; (c) the relationship between integrity of program delivery and program outcomes; and (d) the effectiveness of teacher training and school principal involvement in increasing implementation. METHODS: Participants were teachers (n = 60), school principals (n = 25), and fifth-grade students (n = 1147) from four Los Angeles area school districts. Districts were randomly assigned to an intensive or brief teacher training condition. Schools were randomly assigned to a principal-intervention or a no-principal-intervention condition. Assessments included teacher and principal self-reports, classroom observations of program delivery, and evaluation of immediate program outcomes. RESULTS: During the first year, 78% of trained teachers implemented one or more program lessons. During the second year, only 25% maintained implementation of the program. Implementors reported fewer years of teaching experience and stronger self-efficacy, enthusiasm, preparedness, teaching methods compatibility, and principal encouragement than did nonimplementors. The principal intervention increased rates of implementation, but the intensive teacher training did not. Integrity of program delivery was positively associated with immediate program outcomes. CONCLUSIONS: Program implementation was highly variable, suggesting that widespread teacher use of psychosocial-based programs cannot be taken for granted. Strategies for increasing implementation and maintenance need to be developed.

Family preservation and family support programs: child maltreatment outcomes across client risk levels and program types.

OBJECTIVES: This study evaluated client-level outcomes among an entire statewide group of Family Preservation and Family Support (FPFS) programs funded under PL 103-66. METHOD: A total of 1,601 clients (primarily low income, moderate to high risk with no current involvement in the child protection system) were assessed and followed over time for future child maltreatment events reported to Child Protective Services. The study compared program completers with program dropouts, compared recipients of more lengthy full-service programs with recipients of one-time services, and examined the effects of program duration, intensity, service site (center-based vs. home based) and service model/content. Effects were modeled using survival analysis and variable-exposure Poisson hierarchical models, controlling for initial client risk levels and removing failure events because of surveillance bias. Changes in lifestyle, economic and risk factors were also examined. RESULTS: A total of 198 (12.2%) participants had at least one defined failure event over a median follow-up period of 1.6 years. Controlling for risk and receipt of outside services, program completers did not differ from program dropouts or from recipients of one-time services, and there was no relationship between program intensity or duration and outcomes. Program types designed to help families meet basic concrete needs and programs using mentoring approaches were found to be more effective than parenting and child development oriented programming, and center-based services were found to be more effective than home-based services, especially among higher risk parents. CONCLUSIONS: The findings did not support the effectiveness of these services in preventing future maltreatment cases, and raised questions about a number of common family support assumptions regarding the superiority of home-visiting based and parent training services. A number of possible reasons for this are explored.

A community education monitoring system: methods from the Stanford Five-City Project, the Minnesota Heart Health Program and the Pawtucket Heart Health Program.

Understanding the process of behavior change interventions is critical to achieving campaign effectiveness and successful program replication. The present article presents a community education monitoring system (CEMS) using data from the Stanford Five-City Project (FCP), the Minnesota Heart Health Program (MHHP) and the Pawtucket Heart Health Program (PHHP). CEMS records the number and type of intervention activities, outcome objectives, targets of change (individual, organizational or environmental), channel(s) of dissemination and proportion of programs funded by the community. These data illustrate (1) the application of theory for each project, (2) data-based program administration, (3) feedback for revising programs and (4) type of reach or 'dose' information obtained from intervention monitoring. Process evaluations such as CEMS provide critical links between field realities and evaluation outcomes. This type of evaluation develops standards for measuring program reach and allows comparisons with other programs. CEMS also illustrates how programs enact theory. Validation studies are critical to the continued successful use of CEMS. The first step, however, is to develop a uniform way of describing complex multichannel behavior change programs. CEMS in a refined form should prove invaluable to health promotion program planners whether in research or service settings.

Program evaluation strategies for community-based health promotion programs: perspectives from the cardiovascular disease community research and demonstration studies.

Community-based programs are being widely adopted in the struggle to prevent chronic disease. Program evaluation of community-based programs involves a particular set of problems stemming from the variety of activities being undertaken simultaneously, the multiple intermediate goals of the programs and the rapidity with which the programs evolve. An analysis of the experience of four large community-based cardiovascular disease research and demonstration studies (Stanford Five-City Project, Minnesota Heart Health Program, Pawtucket Heart Health Program and the German Cardiovascular Prevention Project) provides valuable models, methodologies and strategies for planning and conducting evaluations of public health programs or community studies. By comparing and combining their experiences, the four programs have identified eight categories of evaluation for community studies, including formative evaluation, quality assurance, assessment of delivered dose, assessment of received dose, component program impact, intermediate outcomes, community impact and cost analysis. This paper presents information on the strategies by which each of the four programs addressed these evaluation categories.

Combined internal medicine-psychiatry and family medicine-psychiatry training programs, 1999-2000: program directors' perspectives.

PURPOSE: Despite tremendous growth in the number of combined-training residency programs, little is known about their directorships, financing, recruitment, curricula, and attrition rates, and the practice patterns of graduates. The authors surveyed residency program directors from combined internal medicine-psychiatry (IM/PSY) and family medicine-psychiatry (FP/PSY) programs to provide initial descriptive information. METHOD: Programs' directors were determined from the American Medical Association's Graduate Medical Education Directory and FREIDA online database. Three mailings of a pretested questionnaire were sent to the 40 identified combined IM/PSY and FP/PSY residency programs. RESULTS: A total of 32 directors from 29 programs responded. Most programs were under the dual directorship of representatives from both the psychiatry department and either the internal medicine or the family medicine program. Although most directors responded that the residency program was based in psychiatry, both departments shared in administrative, recruiting, and financial responsibilities. Curricula varied widely, with limited focus on combined training experiences. Graduates (n = 41) tended to practice in academic settings (37%), where both aspects of training could be used. Others practiced in either community mental health centers or traditional private practice settings. The estimated attrition rate from combined residencies was 11%. CONCLUSIONS: Combined-training programs are directed by a diverse group of individuals, including dual-boarded physicians. Curricula vary widely, but most programs are within recommended guidelines. Further prospective studies are warranted to determine predictors of attrition and future practice plans.

Program directors' views of the effect of managed care on substance abuse programs in Los Angeles county.

OBJECTIVE: This study sought information about the effect of managed care on substance abuse treatment programs through a survey of program directors. METHODS: Fifty program directors who supervised a total of 134 substance abuse treatment programs in Los Angeles County completed a survey during the period from January to May 1997 on program changes made in response to managed care, major concerns, the advantages and disadvantages of managed care, and plans for further program changes to succeed in the managed care environment. RESULTS: Program directors reported that the most frequent change made in response to managed care was increased outreach and marketing. Their greatest concern in the managed care environment was being forced to provide the least costly service, rather than the best care for patients. Respondents identified an increased focus on outcomes as an advantage of managed care and restrictions on services due to contractual agreements as a disadvantage. Planned program changes addressed the areas of program structure, types of programs offered, staff composition, revenue generation, referral sources, prevention, outcome measures, relationships with other organizations, and accreditation and certification. CONCLUSIONS: Although some substance abuse treatment programs seem to be reducing their scope or preparing to close in response to managed care, others are developing strategies to survive and even thrive in this new economic environment.

Do training programs help AFDC recipients leave the welfare rolls? An evaluation of New York City's BEGIN (Begin Employment Gain Independence Now) program.

Guided by the Federal Family Support Act of 1988 and the Job Opportunity and Basic Skills Program (JOBS), welfare reform initiatives on state and local levels were designed to foster employability among the public assistance population. Reform has focused on enhancing the supply of labor rather than the demand for labor as a route to labor force participation for the public assistance population. Program reforms assume that, by providing job training, educational services, and training-related expenses, labor market entry of the participating clientele would be facilitated while caseloads and public expenditures would decline. To date, analysis of similar programs in many states indicates that the impact of such programs in reducing public assistance caseloads is marginal. In New York City, despite the large investment of public funds in such programs, prior to this study the outcome of program implementation remained largely unknown. This study evaluates New York City's BEGIN program outcome target defined as the ability of the program to move welfare clients off public assistance and into the labor market. While the results of the study indicate that New York City's BEGIN program does not improve client's odds of leaving welfare, when compared to the odds of a non-participation client, there are several significant findings. The impact of program participation can be distinguished among distinct age groups. While older clients responded positively to BEGIN participation, access to day care was the only factor that significantly improved the probability that clients younger than 36 years of age would leave the welfare rolls within a two-year period. In response to the findings, the researchers suggest that future welfare reform efforts should grant localities broader flexibility to determine their own target population so that resources can be allocated to those groups that are most likely to benefit from specific programs.

State programs for medical diagnosis of child abuse and neglect: case studies of five established or fledgling programs.

OBJECTIVE: To describe the programs for medical diagnosis of child abuse and neglect in three states and efforts to establish state-wide programs in two states. To describe common themes and issues that emerged related to the establishment and maintenance of these programs. METHODS: Five states were selected as case studies to represent a range of experience and type of function embodied in programs that address medical diagnosis of child abuse and neglect. Individuals knowledgeable about the programs or efforts to establish state-wide programs in their home states described these in detail. Inductive analysis was used to identify themes and issues that emerged across the states studied. FINDINGS: Themes emerged in three general areas: funding, services, and training. Findings related to funding were: 1) State funding was vital for initiation of statewide programs; 2) Alliances with other groups with parallel interests were successfully used to garner support for child abuse programs; 3) Services needed to be adequately reimbursed to be sustained; 4) Political climate often affected funding. With regard to services we found: 1) There was no optimal way to organize services, but rather many ways that worked well; 2) It was critical to address local service needs; 3) Provision of standardized quality services was essential. With regard to training: 1) Professional training was an integral part of all statewide programs; 2) New technologies, including televideo, have been explored and implemented to assist in training in statewide programs. CONCLUSIONS: Each state has taken a unique approach to programs for the medical diagnosis of child abuse and neglect. However, there are commonalities, particularly among the states that have been successful in establishing and maintaining comprehensive services and/or training.

[Effectiveness and compliance to a center-based short rehabilitation program with a home-based program for chronic low back pain].

OBJECTIVES: To assess the effectiveness and compliance to a short center-based intensive rehabilitation program followed by a home-based program for chronic low back pain. METHODS: Open prospective study in patients with chronic low back pain. The program included five weekly meetings of 12 day. Followed by a home-based program consigned on a booklet. Evaluation of deficiencies (lumbar and radicular pains on an analog visual scale, Schöber Mac Rae test, distance finger-ground, Shirado test, Sorensen test), disabilities (Quebec functional index), and handicap (analog visual scale) were assessed at J0, five weeks, three months and one year. Compliance was assessed quantitatively (a number of exercises, duration of the meetings, numbers meetings per week) and qualitatively (semi-quantitative ordinal scale). Patient's global opinion on the effectiveness of the program was collected on a semi-quantitative ordinal scale. RESULTS: 60 patients (20 women), aged of 45 +/- 10,4 years, were included. Duration of the symptoms was 110 +/- 123 months. At five weeks, a significant improvement of all parameters was observed. This improvement was maintained at three months. At 12 months, there was no more significant improvement. Compliance to the program was 64,4%. 40.7% of the patient did not realize their exercises correctly. The majority gave up back muscle isometric reinforcement exercises. Score of Shirado test, Quebec index and EVA handicap were significantly different in the group realizing the home-base program. At one year, 79% of the patients regarded this program as useful. CONCLUSION: Although quantitative compliance with the home-based program can be considered as satisfactory, the effectiveness of this intensive rehabilitation program of lumbar decrease after three months. This can be explained by a fast deterioration of qualitative compliance. The effectiveness of a short supervised program between 3 and 6 months associated a more powerful message of motivation must be evaluated.

Short-term effects of a group support program and an individual support program for caregivers of stroke patients.

Caregivers of stroke patients who live at home experience many problems. There is evidence from the literature that caregivers' situations can be improved by teaching them active coping strategies and by offering them information about the disease. This study investigated the short-term effects of two different interventions both with the same contents, and both aimed at enhancing caregivers' confidence in knowledge, active coping strategies, mental well-being, vitality, social support, assertiveness, and at reducing strain. In addition, we investigated which type of support, i.e. a group program or home visits, had the most positive effects. Caregivers of stroke patients from four regions of the Netherlands were assigned in blocks to a control group or one of the intervention programs. To the group program 130 caregivers were assigned, to the home visits 78 caregivers, and to the control group 49 caregivers. Caregivers were interviewed before entering the program and after completion of the program. Multiple stepwise regression analysis was used to determine the effects of the interventions. In the short-term, both interventions (group program and home visits together) contributed significantly to an increase in confidence in knowledge about patient care, and the use of the active coping strategies 'confronting' and 'seeking social support'. The group program achieved a small increase in seeking social support. When only taking into account those caregivers that followed a substantial part of the program (per protocol group) also a medium effect was found from both interventions on perceived self efficacy. When comparing the group program and the home visits, no significant differences in effects were found. The results of the program are considered encouraging. We recommend implementation of more intervention programs that focus on coping and providing information.

[Detectability of glaucomatous visual field defects with the Octopus automatic perimeter. A comparison between program G-1 and programs 31 and 32 and their combinations].

Twenty-three patients between 31 and 76 years of age suffering from either hypertension or glaucoma underwent automatic perimetry with Octopus programs 31 or 32, followed by program G-1. This was done to compare the information content of the latter, new program with that of the former two, long-used in different combinations. Only one eye of any one patient was considered in this study. Using an evaluation program, the G-1 program calculates the so-called "field indices" which help to interpret the results. These field indices are the mean differential light sensitivity threshold (mDLS), the mean defect (MD), the loss variance (LV), and the corrected loss variance (corrected for short-term fluctuations (CLV)). In order to compare programs 31, 32, and their combination 31 + 32, with the field indices of program G-1, the mean DLS was taken from the Delta evaluation program, while the mean defect, the loss variance, and the corrected loss variance were calculated on the basis of programs 31, 32, and the combination of them. The mDLS and mean defect determined with program G-1 were significantly different from those found with programs 31, 32, and the combination of them. On the one hand, this was due to the difference in test patterns, that of G-1 being more centrally weighted; on the other hand, this is indicative of the precision and discrimination capability of Octopus measurements. Calculation of loss variance and corrected loss variance reveals no significant difference between the examination methods as regards these field indices, that is, between G-1 and 31, 32, or 31 + 32.(ABSTRACT TRUNCATED AT 250 WORDS)

Program integrity as a moderator of prevention program effectiveness: results for fifth-grade students in the adolescent alcohol prevention trial.

This study reports the results of a test of the quality of program delivery (program integrity) as a variable that may moderate the effectiveness of alcohol prevention programs. Two theory-based programs, Resistance Training and Normative Education, were delivered to fifth-grade students who were then tested on program relevant mediating variables. Resistance Training was found to improve students' knowledge of peer pressure resistance strategies, their performance on a behavioral assessment of peer pressure resistance skills and the manifestation of their future intentions to drink alcohol. Normative Education was found to improve students' perceptions of a conservative norm regarding alcohol use, facilitated their belief that refusing unwanted offers to drink alcohol could be easily accomplished and reduced their perceptions of the prevalence of alcohol use. Program integrity was measured by program specialists who taught the programs to students and by trained observers. Ratings of program integrity were found to significantly moderate outcomes for three of seven mediating variables. Affected were knowledge of peer pressure resistance strategies, behavioral pressure resistance skills and perceived self-efficacy. These results suggest that the quality of program delivery and reception may play an important moderating function on prevention program effectiveness.
