Adolescent Meaning Making of Past Experience

This study examined the meaning making processes of self-defining memories in adolescents, as well as how they co-construct the narratives of these events with their parents. The sample consisted of 53 students, aged 12-14, who came in for recorded laboratory sessions to discuss self-defining memories with their parents. These sessions were later coded on levels of meaning making and co-construction. These codes were, then, analyzed with the adolescents’ questionnaire scores regarding friendship quality, internalizing, and externalizing behaviors. The data revealed that adolescents and parents were both rated higher for more complex levels of meaning making and that those rated higher for more complex meaning making abilities had better friendship qualities. The implications of these findings were discussed in terms of their importance for parents supporting their children’s emotional expressivity, narrative abilities, and meaning making strategies.

Social capital and adolescent health risk behavior in El Salvador

An emerging body of research suggests that the social capital available in one's social environment, as defined by supportive and caring interpersonal relationships, may provide a protective effect against a number of youth risk behaviors. In exploring the potential protective effect of social capital at school and at home on adolescent health and social risk behavior, a comprehensive youth risk behavior study was carried out in El Salvador during the summer of 1999 with a sample of 984 secondary school students attending 16 public rural and urban schools. The following dissertation, entitled Social Capital and Adolescent Health Risk Behavior in El Salvador, presents three papers centered on the topics of social capital and risk behavior. ^ Paper #1. Dangers in the Adolescent River of Life: A Descriptive Study of Youth Risk Behavior among Urban and Rural presents prevalence estimates of four principal youth risk behavior domains—aggression, depression, substance use, and sexual behaviors among students primarily between the ages of 13 and 17 who attend public schools in El Salvador. The prevalence and distribution of risk behaviors is examined by gender, geographic school location, age, and subjective economic status. ^ Paper #2. Social Capital and Adolescent Health Risk Behavior among Secondary School Students in El Salvador explores the relationship between social resources (social capital) within the school context and several youth risk behaviors. Results indicated that students who perceived higher social cohesion at school and higher parental social support were significantly less likely to report fighting, having been threatened or hurt with a weapon, suicidal ideation, and sexual intercourse than students with lower perceived social cohesion at school and parental social support after adjusting for several socio-demographic variables. ^ Lastly, paper #3. School Health Environment and Social Capital : Moving beyond the individual to the broader social developmental context provides a theoretical and empirical basis for moving beyond the predominant individual-focus and physical health concerns of school health promotion to the larger social context of schools and social health of students. This paper explores the concept of social capital and relevant adolescent development theories in relation to the influence of social context on adolescent health and behavior. ^

Determining acquisition and cessation antecedents to adolescent cigarette smoking for development of intervention strategies

Our national focus and emphasis on the promotion of healthy behavior choices regarding tobacco and other drugs continues to target adolescents. Multiple studies have shown that adolescence is the optimum period for the prevention of substance use initiation as life-long patterns of health behaviors are established during this critical developmental stage. Tobacco use is associated with an increase in morbid and mortal health conditions of which prevalence increases throughout the lifespan. Attention to the antecedents of preventable health conditions aims to modify the risks and identify health promotion factors. Modifying antecedent factors for tobacco initiation in youth and identifying protective factors for successful smoking cessation has major public health implications across the lifespan. Of foremost interest are those risk factors and resultant behaviors that predict a youth's probability of initiating cigarette use and their cessation of cigarette use. Specifically, this dissertation supports previous results identifying intervention variables on the initiation/cessation continuum model especially with the established predictors of smoking (decisional balance and susceptibility) and with more recently identified predictors of smoking (nicotine dependence and withdrawal symptoms) in current and former smokers in a sample of high school students in Austin and Houston, Texas. These results offer insight for the development of appropriate intervention program strategies for our youth. ^

Family stress, coping, communication, and adaptation in unintended adolescent pregnancy

Objective. This study examines post-crisis family stress, coping, communication, and adaptation using the Double ABC-X Model of Family Adaptation in families with a pregnant or postpartum adolescent living at home. ^ Methods. Ninety-eight pregnant and parenting adolescents between ages 14 and 18 years (Group 1 at 20 or more weeks gestation; Group 2 at delivery and 8 weeks postpartum) and their parent(s) completed instruments congruent with the model to measure family stress, coping, communication, and adaptation. Descriptive family data was obtained. Mother-daughter data was analyzed for differences between subjects and within subjects using paired t-tests. Correlational analysis was used to examine relationships among variables. ^ Results. More than 90% of families were Hispanic. There were no significant differences between mother and daughter mean scores for family stress or communication. Adolescent coping was not significantly correlated to family coping at any interval. Adolescent family adaptation scores were significantly lower than mothers' scores at delivery and 8 weeks postpartum. Mean individual ratings of family variables did not differ significantly between delivery and 8 weeks postpartum. Simultaneous multiple regression analysis showed that stress, coping, and communication significantly influenced adaptation for mothers and daughters at all three intervals. The relative contributions of the three independent variables exhibited different patterns for mothers and daughters. Parent-adolescent communication accounted for most of the variability in adaptation for daughters at all three intervals. Daughters' family stress ratings were significant for adaptability (p = .01) during the pregnancy and for cohesion (p = .03) at delivery. Adolescent coping (p = .03) was significant for cohesion at 8 weeks postpartum. Family stress was a significant influence at all three intervals for mothers' ratings of family adaptation. Parent-adolescent communication was significant for mother's perception of both family cohesion (p < .001) and adaptability (p < .001) at delivery and 8 weeks, but not during pregnancy. ^ Conclusions. Mothers' and daughters' ratings of family processes were similar regarding family stress and communication, but were significantly different for family adaptation. Adolescent coping may not reflect family coping. Family communication is a powerful component in family functioning and may be an important focus for interventions with adolescents and parents. ^

Psychiatrists' and Psychiatric APRNs' Views of the Adolescent Mental Health Nurse's Role In the Inpatient Setting

Current perceptions about nurses’ roles and responsibilities are examined in this study, specifically relating to adolescent inpatient MHNs. Psychiatrists and psychiatric advanced practice registered nurses (APRNs), who work with MHNs and have also published scholarly psychiatric articles, were contacted to request their participation in an anonymous survey hosted by SurveyMonkey.com. This research was conducted to examine the stereotypes that exist against nurses within the health care profession itself, as compared to the pre-existing stereotypes displayed by the media’s view of nurses. Due to investigator time constraints, only six subjects participated in the study. Analysis of survey responses revealed four overarching themes. First, MHNs are a critical component of the health care team, emerging as rigorous, independent leaders, although still classified as female and sociable. Second, MHNs complete a wide range of daily activities, many of which go unnoticed by observers, often resulting in mixed feelings regarding whether MHNs are given the respect and recognition deserved. Third, MHNs treat each patient as a person with unique thoughts, feelings, and physical make-up. Fourth, MHNs act as a coordinator of care between various health professionals to provide the patient with a holistic approach to healing.

Adolescent Pregnancy Prevention in San Jose, Costa Rica : Assessment of an Educational Intervention

This thesis explores adolescent pregnancy in San Jose, Costa Rica and examines a school-based pregnancy prevention intervention. The relationships between school, gender and risk of adolescent pregnancy are also analyzed, and recommendations are made for effective pregnancy prevention programming. The Purral region of Guadalupe on the outskirts of San Jose, Costa Rica, suffers a higher rate of adolescent pregnancy compared to the rest of the country. In response to this problem, the International Health Central American Institute (IHCAI) implemented a sexual health education program in two local secondary schools in 2006. Very little information about the program is available. It is known that the program was initially evaluated through assessments of the participants’ knowledge before and after the educational sessions. There was no evaluation of the youth attitudes or behaviors, adolescent pregnancies, or long-term impact. The author worked with IHCAI in San Jose, Costa Rica to perform an assessment of the longer term effects of this sexual health education program. They developed a questionnaire to evaluate the knowledge, attitudes, and behaviors surrounding sexual health of youth in the Purral community. Researchers at IHCAI later used this survey to collect data from adolescents who had participated in the educational intervention and those who had not. This thesis analyzes the data collected by IHCAI to assess the effectiveness of the - 2 - educational intervention and the influence of other factors on the knowledge, attitudes, and behaviors of adolescents in the Purral region. The thesis begins with an overview of adolescent pregnancy, Costa Rica and the Purral region, and a description of the education intervention implemented by IHCAI. The research goal, logic model, and methods are then described. The results are reported, and the thesis then concludes with discussion of the results as well as study limitations and recommendations for future research and intervention. This thesis will be used to guide IHCAI’s continuation and expansion of adolescent pregnancy prevention programming.

Adolescent tobacco use: Studies of prevalence, factorial validity, and factorial invariance between African Americans and Whites

In the last thirty years, increasing efforts have been made to reduce the prevalence of adolescent tobacco use in the United States. Although the prevalence has declined dramatically over the past decade, there are still sharp differences in adolescent smoking-initiation rates across racial/ethnic groups. Large-scale surveys frequently assess smoking-related attitudes, self-efficacy, and intentions to explain the differences in smoking rates between African Americans and Whites. However, there is little agreement about which constructs are significant. Moreover, the psychometric properties of smoking-related attitude, self-efficacy, and intention constructs have not been fully examined. More studies are needed to understand existing patterns of tobacco use and to validate and fully exploit the constructs' relationship to adolescent smoking initiation across racial/ethnic groups. ^ This dissertation reports on a secondary analysis of data from a large multi-ethnic convenience sample of sixth- through eighth-grade students in 22 schools in East Texas and the city of Houston. The specific aims of this dissertation were to (1) describe smoking and alternate tobacco product use rates by race/ethnicity, gender, age, and grade level (Article 1); (2) test the factorial validity of smoking-related attitudes, self-efficacy, and intentions using confirmatory factor analysis techniques (Article 2); and (3) test the factorial invariance of smoking-related attitudes, self-efficacy, and intentions between African Americans and Whites (Article 3). ^ The prevalence findings confirm the disparities in tobacco use among African American, Hispanic, and White adolescents that other surveys have reported (Article 1). This study also demonstrates the usefulness of examining use patterns of not only cigarettes but also alternative tobacco products in younger multiethnic populations, as well as of providing epidemiological data estimates about different phases of smoking. The confirmatory factor analysis provides evidence of construct validity of attitude, self-efficacy, and intention scales for the multiethnic sample (Article 2). Finally, the factorial invariance analyses indicates that some measures representing smoking-related attitudes, self-efficacy, and intentions may not be appropriate for use among both African Americans and Whites (Article 3). Additional research is needed to further our understanding of the patterns and predictors of youth tobacco use initiation. ^

Psychosocial and environmental predictors of calcium intake, physical activity and bone health among adolescent girls

Objectives. The purpose of this study was to identify the psychosocial and environmental predictors and the pathways they use to influence calcium intake, physical activity and bone health among adolescent girls. Methods. A secondary data analysis using a cross-sectional and longitudinal study design was implemented to examine the associations of interest. Data from the Incorporating More Physical Activity and Calcium in Teens (IMPACT) study collected in 2001-2003 were utilized for the analyses. IMPACT was a 1½ year nutrition and physical activity intervention study conducted among 718 middle-school girls in central Texas. Hierarchical regression modeling and Structural Equation Modeling (SEM) were used to determine the psychosocial predictors of calcium intake, physical activity and bone health at baseline. Hierarchical regression was used to determine if psychosocial factors at baseline were significant predictors of calcium intake and physical activity at follow-up. Data was adjusted for included BMI, lactose intolerance, ethnicity, menarchal status, intervention and participation in 7th grade PE/athletics. Results. Results of the baseline regression analysis revealed that calcium self-efficacy and milk availability at home were the strongest predictors of calcium intake. Friend engagement in physical activity, physical activity self-efficacy and participation in sports teams were the strongest predictors of physical activity. Finally, physical activity outcome expectations, social support and participation in sports teams were significant predictors of stiffness index at baseline. Results of the baseline SEM path analysis found that outcome expectations and milk availability at home directly influenced calcium intake. Knowledge and calcium self-efficacy indirectly influenced calcium intake with outcome expectations as the mediator. Physical activity self-efficacy and social support had significant direct and indirect influence on physical activity with participation in sports teams as the mediator. Participation in sports teams had a direct effect on both physical activity and stiffness index. Results of regression analysis for baseline predicting follow-up showed that participation in sports teams, self-efficacy, outcome expectations and social support at baseline were significant predictors of physical activity at follow-up. Conclusion. Results of this study reinforce the relevance of addressing both, psychosocial and environmental factors which are critical when developing interventions to improve bone health among adolescent girls. ^

The association of food sources of calcium with weight class in adolescent girls

To determine the association of food sources of calcium with weight class in adolescent girls, the major food sources of calcium were determined for 718 sixth grade girls at three different time periods during an 18 month school-based health intervention program using a FFQ. To determine weight class, the BMI of each girl was stratified using CDC age and gender specific criteria at each time period. The percent contribution of the major food sources of calcium to total calcium intake was compared among the different weight classes at each time period, among those girls who had changed weight class at the different time periods and for those girls who did not change weight class at the different time periods. The mean total calcium intake increased by 20% between the first two time periods and by 12% between the first and last time periods with the intervention despite baseline total calcium intake already being greater than the recommended 1300 mg/day. The percent contribution of the major food sources of calcium were highly correlated among the weight classes that were compared throughout the study. Those girls who remained in the normal weight class throughout the study had the most consistent intake of food sources of calcium. Their top four food sources of calcium were different types of milk which provided greater than 50% of their total calcium intake. Despite there being no significant differences in the major food sources of calcium among the different weight classes, these data show a successful intervention for increasing calcium intake among adolescent girls. ^

A systematic review of community-based participatory research interventions in pediatric and adolescent populations

Background. Community-based participatory research (CBPR) is a collaborative approach to research actively involving community members in all aspects of the research process. CBPR is not a new research method, but an approach that has gained increased attention in the field of public health over the last several years. Recognition of the inequalities in health status associated with social and environmental factors have led to calls for a renewed focus on ecological approaches to research. Ecological approaches acknowledge that the health of the community is dependent on an interaction between behavioral and environmental factors affecting the entire population. While many published studies document the benefits of CBPR in difficult-to-reach populations and describe successful implementation of this approach in adult populations, relatively few studies have been conducted in child and adolescent populations. Given that children and adolescents are particularly sensitive to the effects of their physical environments and may also be distrustful of outsiders, ecological approaches involving the community as partners, such as CBPR, may be especially useful in this population. ^ Objective. This thesis reviews published studies using a community-based participatory research approach in children and adolescents to assess the appropriateness of this approach in this population. ^ Method. Studies using CBPR in youth populations were identified using Medline and other Internet searches through both MeSH heading and text-word searches. ^ Results. A total of 16 studies were identified and analyzed for this review. Nine of the sixteen studies were experimental or quasi-experimental design, with Asthma being the most commonly studied disease. ^ Conclusions. While many studies using CBPR were not conducted with the level of scientific rigor typically found in clinical trial research, the studies reviewed each contributed to a greater understanding of the problems they investigated. Furthermore, interventional studies provided lasting benefits to communities under study above what would be found in studies using more traditional research approaches. While CBPR may not be appropriate for all research situations due to the time and resources required, we conclude that is a useful approach and should be considered when conducting community-based research for pediatric and adolescent populations.^

Body mass index trajectories and predictors among 3rd to 12th graders using growth curve mixture modeling the Child and Adolescent Trial for Cardiovascular Health (CATCH) study

This dissertation examined body mass index (BMI) growth trajectories and the effects of gender, ethnicity, dietary intake, and physical activity (PA) on BMI growth trajectories among 3rd to 12th graders (9-18 years of age). Growth curve model analysis was performed using data from The Child and Adolescent Trial for Cardiovascular Health (CATCH) study. The study population included 2909 students who were followed up from grades 3-12. The main outcome was BMI at grades 3, 4, 5, 8, and 12. ^ The results revealed that BMI growth differed across two distinct developmental periods of childhood and adolescence. Rate of BMI growth was faster in middle childhood (9-11 years old or 3rd - 5th grades) than in adolescence (11-18 years old or 5th - 12th grades). Students with higher BMI at 3rd grade (baseline) had faster rates of BMI growth. Three groups of students with distinct BMI growth trajectories were identified: high, average, and low. ^ Black and Hispanic children were more likely to be in the groups with higher baseline BMI and faster rates of BMI growth over time. The effects of gender or ethnicity on BMI growth differed across the three groups. The effects of ethnicity on BMI growth were weakened as the children aged. The effects of gender on BMI growth were attenuated in the groups with a large proportion of black and Hispanic children, i.e., “high” or “average” BMI trajectory group. After controlling for gender, ethnicity, and age at baseline, in the “high BMI trajectory”, rate of yearly BMI growth in middle childhood increased 0.102 for every 500 Kcals increase (p=0.049). No significant effects of percentage of energy from total fat and saturated fat on BMI growth were found. Baseline BMI increased 0.041 for every 30 minutes increased in moderate-to-vigorous PA (MVPA) in the “low BMI trajectory”, while Baseline BMI decreased 0.345 for every 30 minutes increased in vigorous PA (VPA) in the “high BMI trajectory”. ^ Childhood overweight and obesity interventions should start at the earliest possible ages, prior to 3rd grade and continue through grade school. Interventions should focus on all children, but specifically black and Hispanic children, who are more likely to be highest at-risk. Promoting VPA earlier in childhood is important for preventing overweight and obesity among children and adolescents. Interventions should target total energy intake, rather than only percentage of energy from total fat or saturated fat. ^

Social cognitive theory and factors associated with Mexican-American parents' beliefs, attitudes and practices regarding communication with their adolescent children about sex

Latinos have the highest teen birth rate nationally. Cameron County, Texas is primarily Latino (Mexican-American). This mixed-method study (n=43) examines Mexican-American parents of adolescents' beliefs, attitudes and practices regarding communication with their adolescent children about sex. Social Cognitive Theory (SCT) constructs self-efficacy, behavioral determinism, environment, outcome expectations and reciprocal determinism can be influences on frequency and quality of parent-adolescent sex communication.^ This study describes Mexican-American parents' of adolescents recollections of their own experiences associated with learning about sexuality. It also examines the attitudes and practices regarding communication about sex and the self-efficacy and behavioral capability of participants to teach their adolescent children about sex and sexually transmitted infections. ^ Negative childhood experiences (shame, lies and trauma) of the parents in this study played a key role in terms of their desire to communicate more comprehensively about sexuality with their own children than did their parents. While participants' reported low self-efficacy and behavioral capability to communicate with their adolescent children about sex, they reported relatively high frequency and quality of communication, with 75% of participants receiving a high quality score and over 44% reporting frequent communication with their adolescent children about sex. A Chi square analysis and Fisher's Exact Score revealed no association between acculturation status, gender or having a child who has mothered/fathered a baby and the frequency or quality of communication about sex with adolescent children. Study participants also gave specific recommendations for method, content and setting of sex education for their children and themselves. Promotora delivery of information and education in a comfortable, culturally appropriate neighborhood setting, as well as parent –child learning sessions were identified as possible approaches to address improve self-efficacy and behavioral capability of parents communicating with their adolescent children about sex.^ The results of this analysis provide public health practitioners and interested community entities data to identify and develop interventions that use a theoretical, evidence-based framework for culturally appropriate interventions to encourage and equip Mexican-American parents to effectively communicate with their adolescent children about sexuality, and ultimately to address the high rates of teen pregnancy in this U.S.-Mexico border community. ^

Barriers to adolescent and young men's access of reproductive health care

Purpose. The purpose of this study was to identify the health needs and barriers that young men face in accessing health care and family planning services and to identify what health centers can do to attract young men to the clinic. A focus group format was used to elicit ideas from participants. ^ Methods. Forty-eight young men participated in nine focus groups. The young men were asked about the health issues they have, the barriers they face in accessing reproductive health care, and what clinics can do to attract young men to the clinic. Thematic analysis principles were used to identify the main themes that emerged in the focus groups. ^ Results. Sexually transmitted infections (STIs), mental health problems, and drug use were the major health issues that were mentioned in the majority of the focus groups. The main barriers discussed in the focus groups were attitudinal factors such as young men thinking it is unmanly to seek help, emotional factors such as young men not seeking help because of their ego or pride, and institutional factors such as the location of the clinic. The main suggestions for improvements in the health clinic included decreasing waiting times, emphasizing the fact that the clinics are free for males, having more female nurses, and encouraging clinic staff to treat the young men with respect. Young men suggested advertising and promoting the clinic in schools, in the community, and through the media. Focus group participants also provided their input about the design and format of the clinic flyer. ^ Conclusions. Many studies focus on the reproductive health care needs of adolescent and young females. This study has helped to show that young men also have health care needs and face barriers to accessing reproductive health care services.^
