Measuring Youth Perceptions of Being Known and Loved and Positive Youth Development: Cross-National Findings from Rwanda and El Salvador.

Background: Dynamic, relational developmental systems-based models of development emphasize that developmentally-nurturant youth-adult relationships elicit in youth perceptions of being known and loved. Although such perceptions are foundations of positive youth development (PYD), such measures do not exist. Objective: We sought to create a theoretically-predicated measure of youth perceptions of being known and loved by capitalizing on data sets in two countries (Rwanda and El Salvador) wherein a multi-national study of PYD was being conducted by Compassion International (CI). Method: With Rwanda data (n = 1,204, M age = 11.84, 50% CI-supported), exploratory and confirmatory factor analyses enabled refining the measure for robustness and parsimony. Measures of intentional self-regulation, hopeful future expectations, transcendence, and contribution were used for validation of the known and loved measure within the nomological net of constructs proposed in the Lerner and Lerner PYD model. Confirmatory factor analyses supported the use of the model within the El Salvador data set (n = 1,205, M age = 13.03, 51% CI-supported). Results: Robust psychometric properties were established in both national settings. Measurement invariance was found across age, gender, urban-rural location, CI-enrollment status, and nations, and involved both mean differences and correlations among latent factors. Conclusions: The results provide evidence for a theory-predicated measure of youth perceptions of being known and loved and that scores for this construct covary within a nomological net specified in the Lerner and Lerner model of PYD. These findings serve international development organizations seeking theory-predicated measures for use in evaluating PYD programs in low- and middle-income countries.

The Detection of Substitution Adulteration of Paprika with Spent Paprika by the Application of Molecular Spectroscopy Tools.

The spice paprika (Capsicum annuum and frutescens) is used in a wide variety of cooking methods as well as seasonings and sauces. The oil, paprika oleoresin, is a valuable product; however, once removed from paprika, the remaining spent product can be used to adulterate paprika. Near-infrared (NIR) and Fourier transform infrared (FTIR) were the platforms selected for the development of methods to detect paprika adulteration in conjunction with chemometrics. Orthogonal partial least squares discriminant analysis (OPLS-DA), a supervised technique, was used to develop the chemometric models, and the measurement of fit (R2) and measurement of prediction (Q2) values were 0.853 and 0.819, respectively, for the NIR method and 0.943 and 0.898 respectively for the FTIR method. An external validation set was tested against the model, and a receiver operating curve (ROC) was created. The area under the curve (AUC) for both methods was highly accurate at 0.951 (NIR) and 0.907 (FTIR). The levels of adulteration with 100% correct classification were 50-90% (NIR) and 40-90% (FTIR). Sudan I dye is a commonly used adulterant in paprika; however, in this study it was found that this dye had no effect on the outcome of the result for spent material adulteration.

Processes of Religious and Spiritual Influence in Adolescence: A Systematic Review of 30 Years of Research.

This is a systematic review of 30 years (1988-2017) of empirical research on processes of religious/spiritual influence in adolescence. We followed a multi-step process that resulted in 241 studies organized according to eight research questions and the corresponding methods and analyses typically used to address them. We coded these studies based on the dimensions of religiosity/spirituality and the youth outcomes involved. In some cases (quantitative studies of mediation and moderation, as well as qualitative studies) we also coded a third process variable. Results of the coding process revealed a number of interesting patterns. First, religiosity/spirituality is generally adaptive for adolescents, protecting them from negative outcomes (e.g., risk behaviors and mental illness), and promoting positive youth development and flourishing. Nevertheless, in some contexts, religiosity/spirituality may be at least partially maladaptive. Second, there is some evidence, from experimental and longitudinal studies, that relations between religiosity/spirituality and adaptive outcomes are causal. Third, there are numerous complex and dynamic processes by which religiosity/spirituality relate to youth outcomes. In terms of mediation studies, the most salient mediating processes seem to involve religiosity/spirituality dimensions, peers, values/attitudes, and social control/norms. Fourth, religiosity/spirituality is multidimensional, involving various interwoven facets at the individual and ecological levels. Private or personal aspects of religiosity/spirituality (e.g., religious/spiritual importance) tend to be more salient predictors of outcomes than public aspects of religiosity/spirituality (e.g., religious worship service attendance). The results of this systematic review point to promising directions for future research. First, more research is needed studying a broader range of dimensions of religiosity/spirituality, processes of influence, and outcomes. In terms of religiosity/spirituality, much of the prior work has focused on overall religiosity/spirituality, and religious/spiritual behaviors (e.g., worship service attendance). In terms of outcomes, the emphasis has been on religiosity/spirituality protecting against maladaptive outcomes (e.g., substance use). Second, more research is needed examining the role of culture, and using more rigorous methods (e.g., experience sampling, experimental design, longitudinal design, or mixed methods). This systematic review provides a detailed analysis of what is known regarding processes of religious/spiritual influence in the lives of adolescents, and hopefully better positions researchers to move the field forward.

Religion, Spirituality, and Thriving: Transcendent Narrative, Virtue, and Telos.

A theory is proposed to explain how religion/spirituality (R/S) is related to positive youth development and thriving. The concept of telos is employed to define thriving as continued growth through strength-based living that leads to contributing to one's communities and living out one's ethical ideals. Virtue development is proposed as a primary process by which R/S promotes thriving. Virtues are defined as hybrid personality units emerging when characteristic adaptations are given meaning by a transcendent narrative identity. R/S contributes to virtue formation through the ideological, social, and transcendent contexts embedded within religion by providing opportunities to grow both the characteristic adaptations and transcendent narrative identities necessary for virtue formation in youth and, ultimately, thriving. Implications for future research are discussed.

Processes of Religious and Spiritual Influence in Adolescence: Introduction to a Special Section.

This paper serves as the lead article introducing the special section of the Journal of Research on Adolescence focused on processes of religious and spiritual influence during adolescence. The purpose of the special section is to review prior theory and research on the processes by which religiosity and spirituality might influence youth outcomes, present original cutting-edge theory and research on processes of religious and spiritual influence, and point to the most fruitful directions and methodological approaches for future work in the area. The special section is guided by eight research questions which push researchers to go beyond mere bivariate associations between religion/spirituality and youth outcomes to unpacking the processes of influence at work.

The Rapid Detection of Sage Adulteration Using Fourier Transform Infra-Red (FTIR) Spectroscopy and Chemometrics.

Background: Sage, a common term for the various species of the genus Salvia L., is an herb that is mainly used as a seasoning, or for medicinal purposes. Valuable herbs such as sage, are under constant threat from criminals dealing in economically motivated adulteration. Objective: In this study, the development of a rapid screening technique to detect adulteration in sage was developed using FTIR and chemometrics. Method: A range of sage samples were collected, along with possible known adulterants, olive leaves, myrtle leaves, sumac, hazelnut leaves, cistus and phlomis, strawberry tree leaves and sandalwood. The samples were analyzed on the Thermo Nicolet iS5 FTIR with iD7 attenuated total reflectance accessory and diamond crystal. Chemometric techniques were applied to convert this raw spectral data obtained from the instrument into qualitative models. The qualitative chemometric models for adulteration detection were obtained using principal component analysis and orthogonal partial least squares-discriminant analysis following preprocessing of the spectra. Results: The orthogonal partial least squares-discriminant analysis models had a measurement of fit of 0.978 and 0.952 and a measurement of prediction of 0.975 and 0.936 for binary and multiclass models, respectively. The receiver operating curves following external validation had an area under the curve of 1, indicating excellent method performance. Conclusions: The use of FTIR and chemometrics can potentially screen unknown sage samples for adulteration and can be used in the fight against fraud in the herb and spice industry.

Development of a comprehensive analytical platform for the detection and quantitation of food fraud using a biomarker approach. The oregano adulteration case study.

Due to increasing number of food fraud incidents, there is an inherent need for the development and implementation of analytical platforms enabling detection and quantitation of adulteration. In this study a set of unique biomarkers of commonly found oregano adulterants became the targets in the development of a LC-MS/MS method which underwent a rigorous in-house validation. The method presented very high selectivity and specificity, excellent linearity (R2>0.988) low decision limits and detection capabilities (<2%), acceptable accuracy (intra-assay 92-113%, inter-assay 69-138%) and precision (CV<20%). The method was compared with an established FTIR screening assay and revealed a good correlation of quali- and quantitative results (R2>0.81). An assessment of 54 suspected adulterated oregano samples revealed that almost 90% of them contained at least one bulking agent, with a median level of adulteration of 50%. Such innovative methodologies need to be established as routine testing procedures to detect and ultimately deter food fraud.

Varieties of social experience: The religious cultural context of diverse spiritual exemplars.

From cultural developmental and relational developmental systems perspectives, the current study employed an exemplar research design along with qualitative content analysis to gain deeper understanding of how adolescents perceived the social influences on their religious and spiritual development (RSD) among religiously and culturally diverse youth. The sample included interviews of 28 highly spiritual youth aged 12-21 years (M = 17.73 years) from six countries and eight different religious traditions. Analysis revealed that 96% of participants reported multiple relational influences on their RSD and that these persons impacted their religiousness and spirituality through various processes such as teaching and encouragement. Portions of the narrative are presented to reveal how the meaning and influence of these interactions are informed by cultural and religious tradition. The narratives testify to the multifaceted nature of spiritual development and how it is embedded within religious, social, and cultural contexts. Statement of contribution Already known Existing research suggests that adolescent relationships are critical in shaping the religious and spiritual attitudes and practices that youth demonstrate (for reviews, see King & Boyatzis, 2015, Social and Emotional Issues; Mahoney, 2010, Journal of Marriage and Family, 72, 805; Roehlkepartain et al., 2006, The handbook of spiritual development in childhood and adolescence). Parents and peers are significant in shaping adolescents' involvement and beliefs in a religious system (i.e., Denton, 2012, Journal for the Scientific Study of Religion, 5, 42; Desrosiers et al., 2011, Psychology of Religion and Spirituality, 3, 39; French et al., 2011, Journal of Youth Adolescence, 40, 1623). Other studies have noted the importance of faith communities, mentors, or religious educators (see Schwartz et al., 2006, The handbook of spiritual development in childhood and adolescence; Vaidyanathan, 2011, Journal for the Scientific Study of Religion, 50, 366). However, how these relationships exert influence, on what types of youth, and in what circumstances or cultures is not clear. Current contribution Findings demonstrate that a variety of typical individuals influence spiritual development among highly spiritual youth. Although these influential individuals might fall into common categories (e.g., family, friends, pastors, teachers), their influences are experienced through various processes such as role modeling, teaching, and offering support. These influences take on different meaning in different religious and cultural contexts.

Developmental Model of Parent-Child Coordination for Self-Regulation Across Childhood and Into Emerging Adulthood: Type 1 Diabetes Management as an Example.

Developing individuals and their families benefit from a warm and supportive relationship that fosters the development of good self-regulatory skills in the child needed for a host of positive developmental outcomes. Children and parents face special challenges to self-regulation when faced with a child's chronic illness. A developmental model is presented that traces how positive parental involvement is coordinated with a child's self-regulation skills (regulation of cognition, emotion, and behavior) that are essential for positive health management. This involves different temporal patterns of coordination of child and parent (and other close relationships) that lead to accumulating regulatory developments that afford benefits for managing illness. This process begins early in infancy through attachment and develops into childhood and adolescence to involve the coordination of parental monitoring and child disclosure that serves as a training ground for the expansion of social relationships beyond the family during emerging adulthood. The specific case of families dealing with type 1 diabetes is used to illustrate the transactional and dynamic nature of parent-child coordination across development. We conclude that a developmental model of parent-child coordination holds promise for understanding positive health outcomes and offers new methodological and statistical tools for the examination of development of both child and parent.

Adolescents', mothers', and fathers' reports of adherence across adolescence and their relation to HbA1c and daily blood glucose.

This study examined what is measured by adolescents', mothers', and fathers' reports of adolescents' adherence to the type 1 diabetes regimen and how such reports relate to HbA1c and daily blood glucose. Two-hundred fifty-two adolescents (M age = 12.49 at baseline), mothers, and 188 fathers completed an adapted Self-Care Inventory (LaGreca et al. in Child Health Care 19(3):132-139, 1990) every 6 months for 2.5 years, HbA1c was gathered from medical records, and daily number of blood glucose tests (BGT) and blood glucose mean (BGM) were obtained from glucose meters at one time point. A multitrait-multimethod approach decomposing adherence indicated that fathers' reports reflected a stable perception across time, mothers' reports a shared view within the family that varied with HbA1c across time, and adolescents' reports a unique view. Fathers' and mothers' reports were related to HbA1c; adolescents' reports were not, but were uniquely associated with BGT. Family members' adherence reports capture different information across time, with implications for measuring adherence and for family processes.

A comprehensive strategy to detect the fraudulent adulteration of herbs: The oregano approach.

Fraud in the global food supply chain is becoming increasingly common due to the huge profits associated with this type of criminal activity. Food commodities and ingredients that are expensive and are part of complex supply chains are particularly vulnerable. Both herbs and spices fit these criteria perfectly and yet strategies to detect fraudulent adulteration are still far from robust. An FT-IR screening method coupled to data analysis using chemometrics and a second method using LC-HRMS were developed, with the latter detecting commonly used adulterants by biomarker identification. The two tier testing strategy was applied to 78 samples obtained from a variety of retail and on-line sources. There was 100% agreement between the two tests that over 24% of all samples tested had some form of adulterants present. The innovative strategy devised could potentially be used for testing the global supply chains for fraud in many different forms of herbs.

Mediators of Treatment Effects in a Randomized Clinical Trial of Multisystemic Therapy-Health Care in Adolescents With Poorly Controlled Asthma: Disease Knowledge and Device Use Skills.

OBJECTIVE: Determine whether Multisystemic Therapy-Health Care (MST-HC) improved asthma knowledge and controller device use skills among African-American youth with poorly controlled asthma and whether any improvements mediated changes in illness management. METHODS: A randomized controlled trial was conducted with 170 adolescents with moderate to severe asthma. Families were randomized to MST-HC or attention control. Data were collected at baseline and 6 and 12 months after intervention completion. RESULTS: In linear mixed models, adolescents in the MST-HC group had increases in asthma knowledge; asthma knowledge was unchanged for attention control. Controller device use skills increased for adolescents in the MST-HC group, while skills declined for attention control. Both knowledge and skills mediated the relationship between intervention condition and changes in illness management. CONCLUSIONS: Tailored, home-based interventions that include knowledge and skills building components are one means by which illness management in African-American youth with poorly controlled asthma can be improved.

Determination of the Mycotoxin Content in Distiller's Dried Grain with Solubles Using a Multianalyte UHPLC-MS/MS Method.

There are more than 300 potential mycotoxins that can contaminate food and feed and cause adverse effects in humans and animals. The data on the co-occurrence of mycotoxins in novel animal feed materials, such as distiller's dried grain with solubles (DDGS), are limited. Thus, a UHPLC-MS/MS method for the quantitation of 77 mycotoxins and other fungal metabolites was used to analyze 169 DDGS samples produced from wheat, maize, and barley and 61 grain samples. All DDGS samples analyzed were contaminated with 13-34 different mycotoxins. Fumonisins were present in all 52 maize DDGS samples (81.0-6890 µg/kg for fumonisin B1), and deoxynivalenol was present in all 99 wheat DDGS samples (39.3-1120 µg/kg). A number of co-occurring mycotoxins were also identified. Due to the high co-occurrence of mycotoxins, routine screening of the animal feed ingredients is highly recommended to allow the highlighted risks to be effectively managed.

Classification the geographical origin of corn distillers dried grains with solubles by near infrared reflectance spectroscopy combined with chemometrics: A feasibility study.

In this study, 137 corn distillers dried grains with solubles (DDGS) samples from a range of different geographical origins (Jilin Province of China, Heilongjiang Province of China, USA and Europe) were collected and analysed. Different near infrared spectrometers combined with different chemometric packages were used in two independent laboratories to investigate the feasibility of classifying geographical origin of DDGS. Base on the same dataset, one laboratory developed a partial least square discriminant analysis model and another laboratory developed an orthogonal partial least square discriminant analysis model. Results showed that both models could perfectly classify DDGS samples from different geographical origins. These promising results encourage the development of larger scale efforts to produce datasets which can be used to differentiate the geographical origin of DDGS and such efforts are required to provide higher level food security measures on a global scale.

Effects of family treatment on parenting beliefs among caregivers of youth with poorly controlled asthma.

OBJECTIVE: Caregiver involvement is critical in ensuring optimal adolescent asthma management. The study investigated whether multisystemic therapy (MST), an intensive home-based family therapy, was superior to family support for changing beliefs regarding asthma-related positive parenting among caregivers of African-American youth with poorly controlled asthma. The relationship between parenting beliefs and asthma management at the conclusion of the intervention was also assessed. METHODS: A randomized controlled trial was conducted with 167 adolescents with moderate-to-severe, persistent, poorly controlled asthma and their primary caregivers. Families were randomly assigned to MST or family support (FS), a home-based family support condition. Data were collected at baseline and 7-month posttest. Changes in caregiver ratings of importance and confidence for engaging in asthma-related positive parenting were assessed through questionnaire. Illness management was assessed by the Family Asthma Management System Scale. RESULTS: Participation in MST was associated with more change in caregiver beliefs as compared with FS for both importance (t = 2.39, p = .02) and confidence (t = 2.04, p = .04). Caregiver beliefs were also significantly related to youth controller medication adherence at the conclusion of treatment (importance: r = .21, p = .01; confidence: r = .23, p = .004). CONCLUSION: Results support the effectiveness of MST for increasing parental beliefs in the value of asthma-related positive parenting behaviors and parental self-efficacy for these behaviors among families of minority adolescents with poorly controlled asthma.

Individual differences and day-to-day fluctuations in perceived self-regulation associated with daily adherence in late adolescents with type 1 diabetes.

OBJECTIVE: To examine whether individual differences and intraindividual (within-person day-to-day) fluctuations in late adolescents' self-regulation were associated with daily adherence to the type 1 diabetes regimen. METHODS: 110 school seniors (M age = 17.78 years) and their mothers assessed adolescents' skills underlying self-regulation (executive function, attention, self-control, behavioral inhibition and activation, emotion regulation) and adherence, with glycosylated hemoglobin from medical records. Teens completed daily diaries reporting self-regulation failures surrounding monitoring blood glucose, adherence, and number of blood glucose checks each day for 14 days. RESULTS: Hierarchical Linear Models indicated that better daily adherence was associated with teen and mother reports of better self-regulation skills and teens' reports of fewer daily self-regulation failures. Daily adherence was unrelated to temperamental differences in behavioral inhibition and activation. CONCLUSIONS: Results indicate that both individual and intraindividual differences in self-regulation contribute to daily adherence highlighting the importance of daily self-regulatory challenges to adherence.

Longitudinal trajectories of illness perceptions among adolescents with type 1 diabetes.

OBJECTIVES: To examine development in illness perceptions of type 1 diabetes across adolescence and relationships with intelligence, diabetes responsibility, and diabetes outcomes. METHODS: Illness perceptions were measured via the Illness Perceptions Questionnaire at 3 times, every 6 months in 213 adolescents (M age = 13.00; SD = 1.54) with type 1 diabetes. Intelligence and adolescents' perceived responsibility for diabetes were examined, and adolescents' report of adherence and quality of life (QOL), and glycosylated hemoglobin (HbA1c) from medical records addressed diabetes-related outcomes. RESULTS: Linear growth models showed significant increases in perceptions of diabetes coherence, chronicity, consequences, personal and treatment control, and decreases in diabetes cyclicality and parental control across time. More favorable illness perceptions were generally associated with adolescent intelligence at baseline, more adolescent responsibility for management, better adherence and QOL, and lower HbA1c at each time point. CONCLUSIONS: Results suggest that adolescents develop complex illness perceptions, which are associated with better diabetes management.

Multisystemic therapy for high-risk African American adolescents with asthma: a randomized clinical trial.

OBJECTIVE: The primary purpose of the study was to determine whether Multisystemic Therapy adapted for health care settings (MST-HC) improved asthma management and health outcomes in high-risk African American adolescents with asthma. METHOD: Eligibility included self-reported African American ethnicity, ages 12 to 16, moderate to severe asthma, and an inpatient hospitalization or at least 2 emergency department visits for asthma in the last 12 months. Adolescents and their families (N = 170) were randomized to MST-HC or in-home family support. Data were collected at baseline and posttreatment (7 months) based on an asthma management interview, medication adherence phone diary, and lung function biomarker (forced expiratory volume in 1 s [FEV1]). Analyses were conducted using linear mixed modeling for continuous outcomes and generalized linear mixed modeling for binary outcomes. RESULTS: In intent-to-treat analyses, adolescents randomized to MST-HC were more likely to improve on 2 of the measures of medication adherence and FEV1. Per-protocol analysis demonstrated that MST-HC had a medium effect on adherence measures and had a small to medium effect on lung function and the adolescent's response to asthma exacerbations. CONCLUSION: There are few interventions that have been shown to successfully improve asthma management in minority youth at highest risk for poor morbidity and mortality. MST, a home-based psychotherapy originally developed to target behavior problems in youth, improved asthma management and lung function compared to a strong comparison condition. Further follow-up is necessary to determine whether MST-HC reduces health care utilization accounting for seasonal variability. A limitation to the study is that a greater number of participants in the control group came from single-parent families than in the MST group.

Longitudinal trajectories of parental involvement in Type 1 diabetes and adolescents' adherence.

OBJECTIVE: The purpose of this study was to examine longitudinal trajectories of parental involvement and adolescent adherence to the Type 1 diabetes regimen, to determine whether changes in multiple facets of parental involvement over time predicted subsequent changes in adolescents' adherence, and to examine whether adolescent self-efficacy mediated the effect of parental involvement on adherence. METHOD: Two hundred fifty-two adolescents (M age = 12.49 years, SD = 1.53; 53.6% females) diagnosed with Type 1 diabetes mellitus, their mothers, and 188 fathers were enrolled in a 2.5-year longitudinal study. Across 5 time points, up to 252 adolescents and their parents completed measures of adherence, parental involvement (diabetes monitoring, behavioral involvement in diabetes management, and acceptance), and adolescent diabetes self-efficacy. RESULTS: Using multilevel modeling, analyses indicated significant average declines over time in adherence and most indicators of parental involvement. Lagged multilevel models indicated that declines in mothers' and fathers' acceptance and diabetes monitoring predicted subsequent declines in adolescents' adherence. Additional analyses revealed that longitudinal associations between both maternal acceptance and diabetes monitoring and subsequent adolescent adherence were mediated by adolescents' self-efficacy. CONCLUSIONS: Results of this study, which were largely consistent across reporters, highlight the importance of maintaining parental involvement in diabetes across adolescence and suggest that parental involvement is beneficial for adolescents' adherence, in part, because it contributes to higher self-efficacy for diabetes management among adolescents.
