Psychosocial factors influencing weight control behavior of African American women.

The purpose of this descriptive study was to seek directly from college-educated African American women factors which they perceived influenced their individual weight control behavior, and those that influenced African American women collectively. Face-to-face, in-depth interviews were conducted, primarily in their homes, with 36 African American women. Thirteen major categories were identified. Six factors that influenced the women's individual weight control behavior were emotions/feelings, beliefs, life events, self-control, discipline, and commitment. Perceived benefits of the behavior and perceived barriers to the behavior were influential in determining the attractiveness, the type, and the extent of the weight control behavior. Five factors related to the African American culture were identified and described by the women. Recognition of psychosocial determinants of weight control behavior may enable health professionals to design unique interventions relevant to African American women.

Potential risk factors associated with weight control behaviors in elementary and middle school girls.

The purpose of this study was to examine the relationship between weight control behaviors and potential risk factors for disordered eating in a sample of young girls. The McKnight Risk Factor Survey was administered to 523 elementary and middle school girls. In the sample of elementary school girls, results from the multiple regression analyses indicated that frequency/severity of weight control behaviors was associated with body mass index (BMI), self-confidence, peers' weight-related pressures, ethnicity, and the interaction between having divorced/separated parents and BMI. Sensitivity to peers' weight-related pressures and BMI were also associated with weight control behaviors in the middle school girls, along with poor body image, substance use, having divorced/separated parents, and the interaction between having divorced/separated parents and father's pressure for thinness. Longitudinal research is needed to determine how risk factors change over time, beginning in elementary school and continuing through high school.

Limiting restraint use for behavior control: the brain injury rehabilitation unit as a model.

Physical or pharmacologic restraints are often used to control the behavior of patients who are agitated or who demonstrate behavior that is inappropriate or potentially dangerous. Centers that specialize in traumatic brain injury rehabilitation treat many patients who manifest agitated behavior. This article reviews behavior management within a brain injury rehabilitation setting and describes less restrictive restraint systems. A case study of the management of an agitated patient with traumatic brain injury is presented. Possible future trends in the use of restraint systems are discussed.

Behavioral control and resiliency in the onset of alcohol and illicit drug use: a prospective study from preschool to adolescence.

The developmental trajectories of behavioral control and resiliency from early childhood to adolescence and their effects on early onset of substance use were examined. Behavioral control is the tendency to express or contain one's impulses and behaviors. Resiliency is the ability to adapt flexibly one's characteristic level of control in response to the environment. Study participants were 514 children of alcoholics and matched controls from a longitudinal community sample (Time 1 age in years: M=4.32, SD=0.89). Children with slower rates of increase in behavioral control were more likely to use alcohol and other drugs in adolescence. Children with higher initial levels of resiliency were less likely to begin using alcohol.

Behavioral control of abnormal breathing in sleep.

Behavioral control of abnormal breathing in sleep was studied to determine if an intervention procedure could reduce apnea duration and also SaO2 (blood oxygen) desaturation levels. Sleep apnea patients (n = 11) were instructed while awake that tones would be presented in sleep whenever an apnea event occurred. They were told to breathe deeply to the tones and were given practice in doing so. Intervention and nonintervention hours alternated across 2 nights following 2 baseline nights. As expected, during the intervention hours, the duration but not the frequency of apneic events was reduced. The procedure also resulted in higher SaO2 levels during the intervention hours. Daytime sleepiness was not greater following intervention but sleep staging effects were observed. The results are sufficiently promising to warrant additional research.

Some effects of chlorimipramine and imipramine on the schedule-controlled behavior of the pigeon.

The effects of imipramine and chlorimipramine on schedule-controlled behavior were compared by examining the effects of both drugs on the performance of pigeons under a multiple fixed-interval 600-s fixed-ratio 30-response (mult FI 600 FR 30) schedule of grain presentation and under a mult FI 200 FI 200 schedule in which responding in one component was punished. Imipramine decreased the rate of FR 30 responding at slightly lower doses than or the same doses as those needed to decrease the rate of FI 600 responding. In contrast, chlorimipramine decreased the rate of FI 600 responding at lower doses than those needed to decrease the rate of FR responding. These effects of chlorimipramine were similar to those of chlorpromazine subsequently determined in the same pigeons. Imipramine and chlorimipramine increased proportionally more or decreased proportionally less the lower rates of responding during the first half of the FI 600 than the higher rates of responding during the second half. When the effects of imipramine or chlorimipramine on performance under the mult FI 200 FI 200 schedule were determined, both imipramine and chlorimipramine affected the rates of punished responding and unpunished responding similarly. Thus, while some effects of chlorimipramine on the schedule-controlled behavior of the pigeon are similar to the effects of imipramine, other effects of chlorimipramine more strongly resemble those of chlorpromazine in the pigeon.

Attitudes, knowledge, and behavioral control regarding child abuse reporting in middle eastern nursing professionals: A systematic review and meta-analysis.

INTRODUCTION: Child abuse is critically underreported in the Middle East, with up to 90% of cases going unidentified. Nurses play a central role in child protection systems, yet factors influencing their reporting practices in this region have not been comprehensively synthesized. This study aims to review systematically and meta-analyze evidence on Middle Eastern nurses' knowledge, attitudes, and perceived behavioral control regarding child abuse reporting. METHODS: We conducted a systematic review and meta-analysis following PRISMA guidelines. Five databases (PubMed, Scopus, Web of Science, Embase, Cochrane Library) were searched through November 2025. Studies targeting nursing professionals or students in Middle Eastern countries assessing knowledge, attitudes, intention to report, subjective norms, or perceived behavioral control were included. Random-effects meta-analyses were performed with subgroup analyses comparing students and practicing nurses. RESULTS: Fourteen studies comprising 4018 participants across six countries met the inclusion criteria. The pooled knowledge score was 61.64% (95% CI: 50.14-73.14), with nursing students scoring higher than practicing nurses (75.28% vs. 54.79%, p = 0.03). The pooled attitude score was 60.69% (95% CI: 44.82-76.57). Educational interventions significantly improved knowledge (SMD = 1.54, 95% CI: 0.70-2.38, p = 0.0003). The pooled proportion of nurses intending to report suspected abuse was 75% (95% CI: 0.58-0.92). The pooled subjective norm score was 8.02 (95% CI: 7.75-8.29), and the pooled perceived behavioral control score was 24.34 (95% CI: 22.20-26.46). High heterogeneity (I2 > 95%) reflects substantial variability in educational and legal contexts across the region. CONCLUSIONS: Middle Eastern nurses show moderate knowledge and attitudes toward child abuse reporting, with notable gaps among practicing professionals. Educational interventions are effective but should be integrated with systemic reforms, including mandatory reporting legislation and clear protocols.

Schedule-controlled behaviors as determinants of drug response.

Schedule-controlled performances began to be used in assessing the behavioral effects of drugs because of practical advantages over other techniques for studying behavior. Schedule-controlled behavior is, however, of fundamental importance in behavioral pharmacology. It has been found repeatedly that the effects of many drugs depend critically upon the patterns of responding engendered by different schedule contingencies. These dependencies of the effects of drugs on schedule-controlled behavior occur because ongoing behavior is itself an important determinant of drug action.

Comparison of barriers self-efficacy and perceived behavioral control for explaining physical activity across 1 year among adolescent girls.

The absence of longitudinal data about correlates of physical activity during adolescence has hindered the identification of key mediator variables that can be targeted by interventions. Building on the authors' previous report of a cross-sectional analysis, this study compared barriers self-efficacy and perceived behavioral control as predictors of change in 2 levels of physical activity across a 1-year period among a sample of Black and White adolescent girls (N=1,038). Self-efficacy did not predict change in either moderate or vigorous physical activity. In contrast, perceived behavioral control exhibited a longitudinal, independent relationship with change in vigorous physical activity. The authors concluded that perceived behavioral control is an independent predictor of change in vigorous physical activity levels across a 1-year period among a sample of Black and White adolescent girls and warrants study as a potential mediator variable in interventions designed to increase or maintain physical activity.

Multiple factors in short-term behavioral control of protein intake in rats.

The availability and concentration of dietary protein was varied in an examination of the nature of the day-to-day intake of protein solutions by 60-day-old male rats. It was found that the rats consumed a remarkably constant absolute amount of protein each day, adjusting overall caloric intake to maintain protein at a roughly constant proportion of total calories. Factors such as the time of access to a protein source or the extent of prior experience with a protein source were seen to influence the overall constancy of protein intake, whereas daily shifts in preference between two available concentrations of protein did not interfere with such short-term control. The mechanism for this behavioral control is likely to be different from mechanisms mediating the conditioned response to dietary protein, as in the response to dietary amino acid imbalance.

Some effects of local anesthetics on schedule-controlled behavior.

The central effects of local anesthetics were compared with those of d-amphetamine, using the schedule-controlled behavior of the pigeon. Subconvulsant doses of cocaine and d-amphetamine produced similar effects on schedule-controlled behavior that were quite different from the effects of procaine, mepivacaine and lidocaine.

Interaction of haloperidol and SCH 23390 with cocaine and dopamine receptor subtype-selective agonists on schedule-controlled behavior of squirrel monkeys.

Involvement of D1 and D2 dopamine receptors in the effects of cocaine on schedule-controlled behavior was evaluated in squirrel monkeys responding under a multiple fixed-interval 5-min, fixed-ratio 10 schedule (mult FI FR) of food delivery. Cocaine and the D2 agonist quinpirole increased responding under the F1 at certain doses and disrupted the temporal patterning of behavior. Higher doses of these drugs decreased responding. In contrast, the D1 agonist SKF 38393 was devoid of behavioral activity up to 10 mg/kg where response suppression was obtained without significant modification of the temporal distribution of responding. The D2 antagonist haloperidol (0.001-0.03 mg/kg) did not alter the behavioral effects of cocaine up to doses that had pronounced behavioral effects on their own. However, haloperidol attenuated the behavioral effects of quinpirole. In contrast, the D1 antagonist SCH 23390 partially attenuated the response rate-suppressant effects of cocaine without blocking cocaine-induced disruptions of temporal response patterning. SCH 23390 did not antagonize the behavioral effects of SKF 38393. These results suggest that independent stimulation of either D1 or D2 receptors alone does not play a major role in the effects of cocaine on schedule-controlled behavior of squirrel monkeys.

The influence of nurses' attitudes, subjective norms and perceived behavioral control on maintaining patients' privacy in a hospital setting.

The research reported in this article examined the influence of nurses' attitudes, subjective norms and perceived behavioral control on maintaining patients' privacy during hospitalization. The data were gathered from 109 nurses in six internal medicine wards at an Israeli hospital. The research was based on the theories of reasoned action and planned behavior. A positive and significant correlation was shown between nurses' attitude to promoting and maintaining patient privacy and their planned behavior, while perceived behavioral control was the best variable for predicting the nurses' behavior. Better educated nurses believed that they had fewer resources and anticipated more obstacles in acting to promote and maintain patient privacy. This research adds a new dimension to what is already known about nurses' attitudes to maintaining patients' privacy, nurses' planned behavior and their actual behavior. The practical implications of the findings are the identification of factors that influence the attitudes and behavior of nursing staff, which, in turn, will enable allocation of resources for solving difficulties and removing obstacles. The results will allow the formulation of educational programs to guide staff and also the application of policies based on both patient and nursing staff needs.

Adolescents' attitudes about and consumption of low-fat foods: associations with sex and weight-control behaviors.

The objective of the study was to examine adolescents' attitudes about and consumption of low-fat foods by sex and weight-control behaviors. Ninth- to 12th-grade students (n=1,083) in 20 Minnesota high schools completed mail surveys (response rate=74%) as part of baseline measurements (Fall 2001) in a randomized controlled trial (TACOS: Trying Alternative Cafeteria Options in Schools). Linear models examined attitudes and consumption of low-fat foods by sex and weight-control behaviors. Girls were more likely than boys to report positive attitudes and consumption of low-fat foods (all P<.01). Weight-control practices were associated with more positive attitudes about and higher consumption of low-fat foods. Promoting low-fat snacks to adolescents who are interested in weight control may be an effective component of nutrition intervention programs because these students have more positive attitudes about low-fat foods. Dietitians' efforts to educate adolescents about the benefits and healthfulness of low-fat foods would aid intervention programs.
