Pharmacy work: Intrinsic motivation and extrinsic rewards across role and setting.

BACKGROUND: Pharmacists' and pharmacy technicians' stress and job turnover are at an all-time high. Both intrinsic motivations and extrinsic rewards play key roles in workplace satisfaction. Differences in workplace satisfaction have been identified when comparing chain pharmacies, independent pharmacies, and health systems work settings. OBJECTIVES: Cognitive evaluation theory was applied to explore the influence of intrinsic motivations and extrinsic rewards on both pharmacists' and pharmacy technicians' perceptions of motivations and rewards across various workplace settings. METHODS: A 92-item questionnaire was administered to 129 pharmacists and 111 pharmacy technicians. Participants were primarily recruited at a state pharmacy association annual meeting and via online forums. The questionnaire captured participant demographics including role and work setting (i.e., chain, independent, or health systems), demographic variables, and perceptions about work including autonomy, competence, relationships, pay satisfaction, and benefit satisfaction. RESULTS: A 2-way multivariate analysis of covariance was conducted to test hypothesized differences by role (pharmacist or pharmacy technician) and setting (chain, independent, or health systems). Results show pharmacy personnel in independent and hospital systems settings felt more positive about relationships, competence, pay satisfaction, and benefit satisfaction than those in chain settings. There were no role differences between pharmacists and pharmacy technicians on these outcomes. DISCUSSION: These findings highlight challenges of working in chain pharmacy environments. Results reveal that although pay does not differ across work settings, feelings about both the work and compensation satisfaction do vary across settings. Because role did not drive these relationships, this suggests a need to attend to working conditions for pharmacy personnel. CONCLUSION: Intrinsic motivation elements of competence and relationships are statistically different among employment settings. Relationships and feelings of competence are perceived more favorably in independent and health systems, rather than chain settings. More studies on intrinsic motivations of pharmacy employees within these settings are needed.

Vocabulary and automatic attention: The relation between novel words and gaze dynamics in noun generalization.

Words direct visual attention in infants, children, and adults, presumably by activating representations of referents that then direct attention to matching stimuli in the visual scene. Novel, unknown, words have also been shown to direct attention, likely via the activation of more general representations of naming events. To examine the critical issue of how novel words and visual attention interact to support word learning we coded frame-by-frame the gaze of 17- to 31-month-old children (n = 66, 38 females) while generalizing novel nouns. We replicate prior findings of more attention to shape when generalizing novel nouns, and a relation to vocabulary development. However, we also find that following a naming event, children who produce fewer nouns take longer to look at the objects they eventually select and make more transitions between objects before making a generalization decision. Children who produce more nouns look to the objects they eventually select more quickly following the naming event and make fewer looking transitions. We discuss these findings in the context of prior proposals regarding children's few-shot category learning, and a developmental cascade of multiple perceptual, cognitive, and word-learning processes that may operate in cases of both typical development and language delay. RESEARCH HIGHLIGHTS: Examined how novel words guide visual attention by coding frame-by-frame where children look when asked to generalize novel names. Gaze patterns differed with vocabulary size: children with smaller vocabularies attended to generalization targets more slowly and did more comparison than those with larger vocabularies. Demonstrates a relationship between vocabulary size and attention to object properties during naming. This work has implications for looking-based tests of early cognition, and our understanding of children's few-shot category learning.

Ancient Yersinia pestis genomes from across Western Europe reveal early diversification during the First Pandemic (541-750).

The first historically documented pandemic caused by Yersinia pestis began as the Justinianic Plague in 541 within the Roman Empire and continued as the so-called First Pandemic until 750. Although paleogenomic studies have previously identified the causative agent as Y. pestis, little is known about the bacterium's spread, diversity, and genetic history over the course of the pandemic. To elucidate the microevolution of the bacterium during this time period, we screened human remains from 21 sites in Austria, Britain, Germany, France, and Spain for Y. pestis DNA and reconstructed eight genomes. We present a methodological approach assessing single-nucleotide polymorphisms (SNPs) in ancient bacterial genomes, facilitating qualitative analyses of low coverage genomes from a metagenomic background. Phylogenetic analysis on the eight reconstructed genomes reveals the existence of previously undocumented Y. pestis diversity during the sixth to eighth centuries, and provides evidence for the presence of multiple distinct Y. pestis strains in Europe. We offer genetic evidence for the presence of the Justinianic Plague in the British Isles, previously only hypothesized from ambiguous documentary accounts, as well as the parallel occurrence of multiple derived strains in central and southern France, Spain, and southern Germany. Four of the reported strains form a polytomy similar to others seen across the Y. pestis phylogeny, associated with the Second and Third Pandemics. We identified a deletion of a 45-kb genomic region in the most recent First Pandemic strains affecting two virulence factors, intriguingly overlapping with a deletion found in 17th- to 18th-century genomes of the Second Pandemic.

A study to assess the correlation between plasma, oral fluid and urine concentrations of flunixin meglumine with the tissue residue depletion profile in finishing-age swine.

BACKGROUND: Flunixin meglumine (FM) was investigated for the effectiveness of plasma, oral fluid, and urine concentrations to predict tissue residue depletion profiles in finishing-age swine, along with the potential for untreated pigs to acquire tissue residues following commingled housing with FM-treated pigs. Twenty pigs were housed in groups of three treated and one untreated control. Treated pigs received one 2.2 mg/kg dose of FM intramuscularly. Before treatment and at 1, 3, 6, 12, 24, 36, and 48 h (h) after treatment, plasma samples were taken. At 1, 4, 8, 12 and 16 days (d) post-treatment, necropsy and collection of plasma, urine, oral fluid, muscle, liver, kidney, and injection site samples took place. Analysis of flunixin concentrations using liquid chromatography/tandem mass spectrometry was done. A published physiologically based pharmacokinetic (PBPK) model for flunixin in cattle was extrapolated to swine to simulate the measured data. RESULTS: Plasma concentrations of flunixin were the highest at 1 h post-treatment, ranging from 1534 to 7040 ng/mL, and were less than limit of quantification (LOQ) of 5 ng/mL in all samples on Day 4. Flunixin was detected in the liver and kidney only on Day 1, but was not found 4-16 d post-treatment. Flunixin was either not seen or found less than LOQ in the muscle, with the exception of one sample on Day 16 at a level close to LOQ. Flunixin was found in the urine of untreated pigs after commingled housing with FM-treated pigs. The PBPK model adequately correlated plasma, oral fluid and urine concentrations of flunixin with residue depletion profiles in liver, kidney, and muscle of finishing-age pigs, especially within 24 h after dosing. CONCLUSIONS: Results indicate untreated pigs can be exposed to flunixin by shared housing with FM-treated pigs due to environmental contamination. Plasma and urine samples may serve as less invasive and more easily accessible biological matrices to predict tissue residue statuses of flunixin in pigs at earlier time points (≤24 h) by using a PBPK model.

Transcriptomic Analysis of Human Astrocytes In Vitro Reveals Hypoxia-Induced Mitochondrial Dysfunction, Modulation of Metabolism, and Dysregulation of the Immune Response.

Hypoxia is a feature of neurodegenerative diseases, and can both directly and indirectly impact on neuronal function through modulation of glial function. Astrocytes play a key role in regulating homeostasis within the central nervous system, and mediate hypoxia-induced changes in response to reduced oxygen availability. The current study performed a detailed characterization of hypoxia-induced changes in the transcriptomic profile of astrocytes in vitro. Human astrocytes were cultured under normoxic (5% CO2, 95% air) or hypoxic conditions (1% O2, 5% CO2, 94% N2) for 24 h, and the gene expression profile assessed by microarray analysis. In response to hypoxia 4904 genes were significantly differentially expressed (1306 upregulated and 3598 downregulated, FC ≥ 2 and p ≤ 0.05). Analysis of the significant differentially expressed transcripts identified an increase in immune response pathways, and dysregulation of signalling pathways, including HIF-1 (p = 0.002), and metabolism, including glycolysis (p = 0.006). To assess whether the hypoxia-induced metabolic gene changes observed affected metabolism at a functional level, both the glycolytic and mitochondrial flux were measured using an XF bioanalyser. In support of the transcriptomic data, under physiological conditions hypoxia significantly reduced mitochondrial respiratory flux (p = 0.0001) but increased basal glycolytic flux (p = 0.0313). However, when metabolically stressed, hypoxia reduced mitochondrial spare respiratory capacity (p = 0.0485) and both glycolytic capacity (p = 0.0001) and glycolytic reserve (p < 0.0001). In summary, the current findings detail hypoxia-induced changes in the astrocyte transcriptome in vitro, identifying potential targets for modifying the astrocyte response to reduced oxygen availability in pathological conditions associated with ischaemia/hypoxia, including manipulation of mitochondrial function, metabolism, and the immune response.

Home-Based Comprehensive Medication Reviews: Pharmacist's Impact on Drug Therapy Problems in Geriatric Patients.

OBJECTIVE: To evaluate the effects of pharmacist-conducted, home-based comprehensive medication reviews (CMRs) on drug therapy problems (DTPs) in geriatric patients. DESIGN: Pre-/postintervention study. SETTING: Grocery store chain affiliated with three independent living facilities. PARTICIPANTS: Twenty-five older adults using pharmacy delivery services for at least three chronic medications. INTERVENTION: A pharmacist conducted a home-based CMR for each participant. DTPs were identified across 13 categories. Patients received a medication action plan post-CMR. A follow-up patient phone call was completed two weeks following the appointment. Patient profiles were reviewed for three months postintervention for changes in DTPs. MAIN OUTCOME MEASURES: Changes in DTPs per patient and changes in five Centers for Medicare & Medicaid Services triple-weighted Star Rating performance measures. RESULTS: The average DTPs identified per patient were reduced from 3.4 ± 2.06 to 1.48 ± 1.68 (P < 0.05) DTPs three months postintervention. The most common categories identified-nonadherence and incorrect administration/ technique-were significantly reduced (P = 0.012 and P = 0.010, respectively). One Star Rating performance measure significantly improved: 68% of patients taking hypertension medications were adherent at baseline and 91% were adherent three months post-CMR (P = 0.016). CONCLUSION: Pharmacist-provided, home-based CMRs reduced the average number of DTPs per patient. The most common categories of DTPs identified-nonadherence and incorrect administration/technique-were reduced postintervention.

Participant satisfaction with a community-based medication synchronization program.

OBJECTIVE: To assess participant satisfaction with a community pharmacy-based medication synchronization program. SETTING: A single location of a grocery store pharmacy chain in the Kansas City metropolitan area. PRACTICE DESCRIPTION: A medication synchronization program, Time My Meds (TMM), was implemented in 1 of 20 community pharmacies within the grocery store chain. PRACTICE INNOVATION: Current pharmacy patients taking three or more chronic medications were recruited to enroll in the medication synchronization program. After at least 3 months of enrollment in TMM, participants were invited to complete a paper survey to assess satisfaction with the program. EVALUATION: Data were collected on overall participant satisfaction with the TMM program. A 10-statement survey gathered demographic information and assessed participant satisfaction using a 5-point Likert scale (1, strongly disagree, to 5, strongly agree). RESULTS: Data collected from 48 surveys were analyzed. No statistical differences in participant satisfaction were found when considering age, education, income, number of medications at pick-up, or number of monthly trips to the pharmacy prior to program enrollment. Median scores for individual survey items were all 5 out of 5 (strongly agree) using a 5-point Likert scale. CONCLUSION: Participants were highly satisfied with the medication synchronization program. These results, if expanded to a wider population, might provide valuable information for continued justification and implementation of this type of service in community pharmacies.

Pharmacogenomics education strategies in the United States pharmacy school curricula.

BACKGROUND: Clinical pharmacogenomics is an expanding area in healthcare that relies heavily on pharmacists for advocacy and implementation. To support pharmacists' significant roles in clinical pharmacogenomics, pharmacy schools and colleges in the United States (US) have strived to incorporate pharmacogenomics education into their curricula, and various teaching strategies have been employed in recent years to meet pharmacogenomics educational outcomes. The six major strategies reported in the literature are described and compared in this review, which culminates in a proposed longitudinal curriculum design for pharmacogenomics education. METHODS: Publications focused on pharmacogenomics education to pharmacy students within the US in the past decade were evaluated and summarized. RESULTS: The major education strategies that have been studied are didactic lecture, personal genotyping or personal genomic testing, simulation laboratory activity, interprofessional education, practice-based activity such as clinical rotation, and combinational courses. Strengths and limitations of each teaching strategy are summarized and discussed. IMPLICATIONS: Based upon each education strategy's strengths and weaknesses, the authors propose a longitudinal curriculum design to ensure that pharmacogenomics is taught multiple times to pharmacy students with diverse formats and teaching objectives conducive to long-term knowledge retention and practice readiness. Through this longitudinal curriculum design, pharmacy graduates will be well equipped to lead clinical pharmacogenomics in practice.

Selective brain entry of lipid nanoparticles in haemorrhagic stroke is linked to biphasic blood-brain barrier disruption.

Haemorrhagic stroke represents a significant public health burden, yet our knowledge and ability to treat this type of stroke are lacking. Previously we showed that we can target ischaemic-stroke lesions by selective translocation of lipid nanoparticles through the site of blood-brain barrier (BBB) disruption. The data we presented in this study provide compelling evidence that haemorrhagic stroke in mice induces BBB injury that mimics key features of the human pathology and, more importantly, provides a gate for entry of lipid nanoparticles-based therapeutics selectively to the bleeding site. Methods: Haemorrhagic stroke was induced in mice by intra-striatal collagenase injection. lipid nanoparticles were injected intravenously at 3 h, 24 h & 48 h post-haemorrhagic stroke and accumulation in the brain studied using in-vivo optical imaging and histology. BBB integrity, brain water content and iron accumulation were characterised using dynamic contrast-enhanced MRI, quantitative T1 mapping, and gradient echo MRI. Results: Using in-vivo SPECT/CT imaging and optical imaging revealed biphasic lipid nanoparticles entry into the bleeding site, with an early phase of increased uptake at 3-24 h post-haemorrhagic stroke, followed by a second phase at 48-72 h. Lipid nanoparticles entry into the brain post-haemorrhage showed an identical entry pattern to the trans-BBB leakage rate (Ktrans [min-1]) of Gd-DOTA, a biomarker for BBB disruption, measured using dynamic contrast-enhanced MRI. Discussion: Our findings suggest that selective accumulation of liposomes into the lesion site is linked to a biphasic pattern of BBB hyper-permeability. This approach provides a unique opportunity to selectively and efficiently deliver therapeutic molecules across the BBB, an approach that has not been utilised for haemorrhagic stroke therapy and is not achievable using free small drug molecules.

Assessing pharmacy students' knowledge and perceptions of urine drug testing following a pharmacy skills laboratory.

INTRODUCTION: Urine drug tests (UDTs) are commonly used in the healthcare setting to monitor adherence, abuse, and diversion of controlled substances. The goal of our study was to assess the knowledge and perceptions of third-year pharmacy students on UDTs following an educational experience. METHODS: Third-year pharmacy students completed pre- and post-questionnaires following a skills laboratory focused on the use of UDTs in clinical settings. The 34-item questionnaires consisted of three domains: demographics, knowledge regarding UDTs, and personal perceptions of UDTs. A pre-lab teaching podcast was assigned prior to the laboratory session, and two clinical cases were discussed during the live UDT segment. Descriptive statistics were used to assess demographics, and changes in knowledge and perceptions of UDTs were evaluated using chi-square and Mann-Whitney U, respectively, with an a priori alpha of 0.05. RESULTS: One hundred twenty students were included in the analysis. Students in the laboratory were predominately female (n = 72, 60%), Caucasian (n = 84, 70%), and had no prior training with UDTs (n = 104, 86.7%). Student knowledge of UDT interpretation significantly increased from 57% to 71% (four and five correct answers out of seven, respectively). Confidence interpreting UDTs and answering questions related to UDTs also increased significantly. Students felt the laboratory experience was valuable, with 84.2% agreeing or strongly agreeing. CONCLUSIONS: Educational programming focused on UDTs improves student confidence interpreting results and knowledge related to the use of UDTs.

Determining the impact of an interprofessional simulation focused on social determinants of health among pharmacy students.

INTRODUCTION: The purpose of this study was to determine the impact on pharmacy students' self-perception of knowledge, skills, collaborative behavior, and satisfaction after participating in an interprofessional (IP) simulation focused on social determinants of health (SDOH) and substance use. METHODS: Pharmacy students completed a voluntary questionnaire after participating in an IP simulation focused on SDOH and substance use where they collaborated with social work (SW) students. Questions assessed the students' understanding and knowledge of SDOH and students' confidence in asking patients about their substance use, willingness to refer patients to SW, and satisfaction with the simulation. The data were analyzed using a Wilcoxon signed-rank test. RESULTS: Results of pharmacy students' (N = 68) self-reported knowledge of SDOH and skills addressing and counseling on SDOH were improved following an IP simulation. No statistically significant change was observed in students' confidence when asking about or advising a patient on their substance use. There was a positive, significant change in how likely pharmacy students would refer patients to SW (P < .001) in their future practice. CONCLUSIONS: This simulation proved to be an effective way to improve pharmacy students' self-reported knowledge of SDOH and skills for assessing and counseling on resources for SDOH. The simulation was effective in exposing pharmacy students to the role of social workers on the team and how they address SDOH and substance use issues.

Clinical skills temporal degradation assessment in undergraduate medical education.

INTRODUCTION: Medical students' ability to learn clinical procedures and competently apply these skills is an essential component of medical education. Complex skills with limited opportunity for practice have been shown to degrade without continued refresher training. To our knowledge there is no evidence that objectively evaluates temporal degradation of clinical skills in undergraduate medical education. The purpose of this study was to evaluate temporal retention of clinical skills among third year medical students. METHODS: This was a cross-sectional study conducted at four separate time intervals in the cadaver laboratory at a public medical school. Forty-five novice third year medical students were evaluated for retention of skills in the following three procedures: pigtail thoracostomy, femoral line placement, and endotracheal intubation. Prior to the start of third-year medical clerkships, medical students participated in a two-hour didactic session designed to teach clinically relevant materials including the procedures. Prior to the start of their respective surgery clerkships, students were asked to perform the same three procedures and were evaluated by trained emergency medicine and surgery faculty for retention rates, using three validated checklists. Students were then reassessed at six week intervals in four separate groups based on the start date of their respective surgical clerkships. We compared the evaluation results between students tested one week after training and those tested at three later dates for statistically significant differences in score distribution using a one-tailed Wilcoxon Mann-Whitney U-test for non-parametric rank-sum analysis. RESULTS: Retention rates were shown to have a statistically significant decline between six and 12 weeks for all three procedural skills. CONCLUSION: In the instruction of medical students, skill degradation should be considered when teaching complex technical skills. Based on the statistically significant decline in procedural skills noted in our investigation, instructors should consider administering a refresher course between six and twelve weeks from initial training.

Evaluation of pyramid training as a method to increase diagnostic sampling capacity during an emergency veterinary response to a swine disease outbreak.

OBJECTIVE To develop and evaluate a pyramid training method for teaching techniques for collection of diagnostic samples from swine. DESIGN Experimental trial. SAMPLE 45 veterinary students. PROCEDURES Participants went through a preinstruction assessment to determine their familiarity with the equipment needed and techniques used to collect samples of blood, nasal secretions, feces, and oral fluid from pigs. Participants were then shown a series of videos illustrating the correct equipment and techniques for collecting samples and were provided hands-on pyramid-based instruction wherein a single swine veterinarian trained 2 or 3 participants on each of the techniques and each of those participants, in turn, trained additional participants. Additional assessments were performed after the instruction was completed. RESULTS Following the instruction phase, percentages of participants able to collect adequate samples of blood, nasal secretions, feces, and oral fluid increased, as did scores on a written quiz assessing participants' ability to identify the correct equipment, positioning, and procedures for collection of samples. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that the pyramid training method may be a feasible way to rapidly increase diagnostic sampling capacity during an emergency veterinary response to a swine disease outbreak.

Assessment of litter prevalence of Mycoplasma hyopneumoniae in preweaned piglets utilizing an antemortem tracheobronchial mucus collection technique and a real-time polymerase chain reaction assay.

The swine industry currently lacks validated antemortem methods of detecting baseline herd prevalence of Mycoplasma hyopneumoniae. The focus of our study was to evaluate alternative antemortem detection techniques and to determine baseline litter prevalence in preweaned pig populations utilizing the selected technique and a real-time polymerase chain reaction (qPCR) assay. Preliminary data was analyzed on weaned piglets with evidence of respiratory disease (n = 32). Five sample types (antemortem nasal swab, tracheobronchial mucus, postmortem deep airway swab, bronchoalveolar lavage, and lung tissue) were collected from each pig. Individual samples were tested for M. hyopneumoniae using qPCR. Compared to nasal swabs, tracheobronchial mucus demonstrated higher test sensitivity (P < 0.0001). Tracheobronchial mucus was collected from apparently healthy preweaned piglets (n = 1,759; sow farms 1-3) and preweaned piglets exhibiting signs of respiratory disease (n = 32; sow farm 4), ranging in age from 12 to 25 days. Samples from sow farms 1-3 were pooled into 2 groups of 5 per litter (n = 360 pools from 180 litters), and qPCR was utilized to analyze each pool. A qPCR-positive result, threshold cycle <37, from either pool designated the litter positive for M. hyopneumoniae. Two out of 180 litters revealed a positive result (1.1%). Individual qPCR assays were run on the samples collected from sow farm 4. Five out of 30 samples revealed a positive result (16.7%). Tracheobronchial mucus collection in combination with qPCR is a sensitive antemortem sampling technique that can be used to estimate the prevalence of M. hyopneumoniae in preweaned pigs, thus providing insight into the infection dynamics across the entire farrow-to-finish process.

Impact of a community-based diabetes self-management program on key metabolic parameters.

OBJECTIVE: Characterize the impact of a pharmacist-led diabetes self-management program on three key metabolic parameters: glycosylated hemoglobin (HbA1c), low-density lipoprotein cholesterol (LDL-C), and mean arterial blood pressure (MAP) among employee health program participants. METHODS: A self-insured company in the Kansas City metropolitan area began offering a pharmacist-led diabetes self-management program to eligible company employees and their dependents in 2008. A retrospective pre-post analysis was conducted to determine if the program affected key metabolic parameters in participants by determining mean change after one year of participation. RESULTS: Among 183 program participants, 65 participants met inclusion criteria. All three key metabolic parameters were significantly reduced from baseline to one year of program participation: HbA1c decreased from 8.1 % to 7.3% (p=0.007); LDL-C decreased from 108.3 mg/dL to 96.4 mg/dL (p=0.009); and MAP decreased from 96.1 to 92.3 mm Hg (p=0.005). CONCLUSIONS: The pharmacist-led diabetes self-management program demonstrated significant reductions in HbA1c, LDL-C, and MAP from baseline to one year of program participation. Improvements were statistically significant and clinically relevant for each parameter. Previous studies indicate these reductions may cause reduced overall healthcare costs.

Impact of transmammary-delivered meloxicam on biomarkers of pain and distress in piglets after castration and tail docking.

To investigate a novel route for providing analgesia to processed piglets via transmammary drug delivery, meloxicam was administered orally to sows after farrowing. The objectives of the study were to demonstrate meloxicam transfer from sows to piglets via milk and to describe the analgesic effects in piglets after processing through assessment of pain biomarkers and infrared thermography (IRT). Ten sows received either meloxicam (30 mg/kg) (n = 5) or whey protein (placebo) (n = 5) in their daily feedings, starting four days after farrowing and continuing for three consecutive days. During this period, blood and milk samples were collected at 12-hour intervals. On Day 5 after farrowing, three boars and three gilts from each litter were castrated or sham castrated, tail docked, and administered an iron injection. Piglet blood samples were collected immediately before processing and at predetermined times over an 84-hour period. IRT images were captured at each piglet blood collection point. Plasma was tested to confirm meloxicam concentrations using a validated high-performance liquid chromatography-mass spectrometry method. Meloxicam was detected in all piglets nursing on medicated sows at each time point, and the mean (± standard error of the mean) meloxicam concentration at castration was 568.9±105.8 ng/mL. Furthermore, ex-vivo prostaglandin E2 (PGE2) synthesis inhibition was greater in piglets from treated sows compared to controls (p = 0.0059). There was a time-by-treatment interaction for plasma cortisol (p = 0.0009), with meloxicam-treated piglets demonstrating lower cortisol concentrations than control piglets for 10 hours after castration. No differences in mean plasma substance P concentrations between treatment groups were observed (p = 0.67). Lower cranial skin temperatures on IRT were observed in placebo compared to meloxicam-treated piglets (p = 0.015). This study demonstrates the successful transfer of meloxicam from sows to piglets through milk and corresponding analgesia after processing, as evidenced by a decrease in cortisol and PGE2 levels and maintenance of cranial skin temperature.

Confidence as a predictor of sexual and reproductive health outcomes for youth.

PURPOSE: To assess the association between four positive youth development (PYD) constructs of confidence and adolescent sexual and reproductive health (ASRH) outcomes. METHODS: We searched nine online databases to locate behavioral research that examined the association between four constructs of confidence (belief in the future, self-determination, clear and positive identity, and self-efficacy) and ASRH outcomes (e.g., ever had sex, condom use, contraception use, number of partners, pregnancy/birth, and sexually transmitted infection). Findings were coded as "protective," "risk," or "no association." The presence of at least two longitudinal studies reporting consistent significant associations for at least one ASRH outcome indicated evidence for a protective or risk association. RESULTS: We found evidence to support two of the four PYD constructs of confidence (belief in the future and self-determination) as protective factors for ASRH outcomes. Evidence was insufficient to draw conclusions about clear and positive identity as a protective factor, and was mixed for self-efficacy. Measures of confidence varied considerably across the studies reviewed, reflecting varying definitions; often, the measures used had limited information on reliability. Few longitudinal investigations were identified, and available studies were inconsistent in how they examined the association between the PYD constructs and ASRH outcomes. Evidence for most constructs was insufficient to identify their influence on specific sub-groups of youth. CONCLUSIONS: Despite the need for additional research, this review suggests that belief in the future and self-determination are promising protective factors. Further research is needed to better understand the potential for self-efficacy and clear and positive identity as protective factors.

Competence as a predictor of sexual and reproductive health outcomes for youth: a systematic review.

To examine the association between "competence" and adolescent sexual and reproductive health (ASRH) outcomes. Competence refers to the development of skills to perform tasks successfully in four areas including social and behavioral, cognitive, emotional, and moral competence. We conducted a systematic review of research published from 1985 through 2007. Inclusion criteria included use of multivariate analyses, a sample size of >or=100, publication in a peer-reviewed journal, and measurement of an ASRH outcome. We coded findings as protective, risk, or no association and as longitudinal or cross-sectional. We considered the presence of two longitudinal studies with consistent findings for at least one outcome to be sufficient evidence for a risk or protective association. We identified 77 studies that examined cognitive competence, 27 studies that examined social and behavioral competence, 12 studies that examined emotional competence, and no studies that met inclusion criteria for moral competence. The evidence indicated that cognitive competence and social and behavioral competence can be protective factors for ASRH, with findings from at least two longitudinal studies demonstrating a protective association with an ASRH outcome. Findings across cognitive, social and behavioral subconstructs and ASRH outcomes were more mixed. There was insufficient evidence to draw conclusions about emotional and moral competence and ASRH. Helping adolescents to achieve cognitive, social, and behavioral competence may reduce the likelihood of sexual activity and teen pregnancy, and increase contraceptive use. Additional research is needed to examine other outcomes and the generalizability of findings.
