Predictors of mentoring relationship quality: Investigation from the perspectives of youth and parent participants in Big Brothers Big Sisters of Canada one-to-one mentoring programs.

AIMS: This study examined predictors of mentoring relationship quality (MRQ) as reported by youth and parents participating in Big Brothers Big Sisters (BBBS) of Canada one-to-one mentoring programs. METHODS: Mentoring program capacity and other external supports, youth personal and environmental risk, youth and parent attitudes and motives, and mentoring relationship processes and attributes were examined as predictors of MRQ at 18 months following youth referral to the program using data from a longitudinal study of the Canadian BBBS mentoring programs. RESULTS: For youth (n = 335), significant predictors of MRQ included: minimal difficulties pairing youth and mentors, perceptions of shared attributes with their mentor, mentor emotional engagement and support, and longer relationships. For parents (n = 356) higher MRQ was correlated with parent report of minimal difficulties pairing youth and mentors, a high-quality relationship with the youth's mentor, and longer relationships. CONCLUSION: Implications for program and policy development are discussed.

How Mentor Support Interacts With Mother and Teacher Support in Predicting Youth Academic Adjustment: An Investigation Among Youth Exposed to Big Brothers Big Sisters of Canada Programs.

This study examines three potential contributions (i.e., additive only, hierarchical compensatory, and hierarchical conditional) of mentor support to youth academic adjustment, taking into account interactions with support from mothers and teachers. We derived data from a larger study of the Big Brothers Big Sisters (BBBS) of Canada community mentoring program. The sample included 427 youth (average age 9.8 years; 64% girls, 56% White) who received one-to-one community-based mentoring for at least three months. We assessed perceptions of support from mothers and teachers before the match and assessed perceptions of support from mentors five times throughout the mentoring experience. Hierarchical linear regression analyses showed that mentor support predicted positive changes in youth academic adjustment (i.e., school attitude, academic self-efficacy, assistance seeking, and problem solving) mainly when mentees already reported high support from their mother. This finding clearly supports the conditional model and invites researchers to question the assumption that mentoring constitutes a corrective experience for young people (i.e., the compensatory model). BBBS agencies are strongly encouraged to involve parents in the mentoring process and to view them as experts, assets, and allies in their effort to meet the youth's needs.

Appropriate Use of Venous Imaging and Analysis of the D-Dimer/Clinical Probability Testing Paradigm in the Diagnosis and Location of Deep Venous Thrombosis.

BACKGROUND: The D-dimer (DD) level combined with the pretest Wells criteria probability (WCP) score can safely exclude deep venous thrombosis (DVT). The objective of this study was to examine the correlation between DD results alongside WCP score with findings on venous duplex ultrasound (VDU). The hypothesis is that VDU remains overutilized in low-risk patients with negative DD and that higher DD levels may correlate with thrombus burden and location. METHODS: Patients who presented to a high-volume tertiary care center with lower limb swelling with or without associated pain were retrospectively examined through June and July for 4 consecutive years (2012 to 2015). After calculating WCP, patients were divided into low-, moderate-, and high-risk categories. Electronic DD results utilizing enzyme linked immunosorbent assay, WCP data, and VDU analysis data were merged and analyzed based on receiver operator characteristic curve to determine the DD cutoff point for each WCP. Abnormal DD with an average value ≥ 0.6 mg/L fibrinogen equivalent units (FEUs) was correlated to positive DVT to differentiate proximal DVT (above popliteal vein) from distal DVT (below popliteal vein). RESULTS: Data of 1,909 patients were analyzed, and 239 (12.5%) patients were excluded secondary to serial repeat visits or follow-ups, surveillance screens, and if they had a previous history of DVT. The average age was 62.1 ± 16.3 years with more women (55.7%) and the majority presented with limb pain and edema (87%). DD studies were ordered and completed in 202 patients and correlated with all positive and negative DVT patients (100% sensitivity and negative predictive value, with specificity and positive predictive value of 14.9% and 15.9%, respectively). Twenty-six of 202 patients had DD that were in the normal range 0.1-0.59 mg/L (FEU), all of which were negative for DVT (100% sensitive). Fifty one of 202 patients had DD values of 0.6-1.2 mg/L FEU, of which only 3 DVTs were recorded, and all of them were distal DVTs. In addition, 685 patients with WCP <1 and negative DD were sent for VDU. Thus, 762 patients had an unnecessary immediate VDU (Wells ≤1 and -DD) study during their initial presentation. Potential charge savings for VDU for all patients are 762 × $1,557 = $1,186,434 and DD for all patients are 762 × $182 = $138,684, with total potential savings of $1,047,750 (USD 2016). CONCLUSIONS: This study suggests that DD is still underutilized, and DD in conjunction with WCP could significantly reduce the number of unnecessary immediate VDUs. Higher value of DD (>1.2 mg/L FEU) may raise concern for proximal DVT. Concern on cost-effectiveness exists and raises the demand for a proposed algorithm to be followed.

Examining the validity of the adapted Alabama Parenting Questionnaire-Parent Global Report Version.

The purpose of the present study was to comprehensively examine the validity of an adapted version of the parent global report form of the Alabama Parenting Questionnaire (APQ) with respect to its factor structure, relationships with demographic and response style covariates, and differential item functioning (DIF). The APQ was adapted by omitting the corporal punishment and the other discipline items. The sample consisted of 674 Canadian and United States families having a 9- to 12-year-old child and at least 1 parent figure who had received treatment within the past 5 years for alcohol problems or met criteria for alcohol abuse or dependence. The primary parent in each family completed the APQ. The 4-factor CFA model of the 4 published scales used and the 3-factor CFA model of those scales from prior research were rejected. Exploratory structural equation modeling was then used. The final 3-factor model combined the author-defined Involvement and Positive Parenting scales and retained the original Poor Monitoring/Supervision and Inconsistent Discipline scales. However, there were substantial numbers of moderate magnitude cross-loadings and large magnitude residual covariances. Differential item functioning (DIF) was observed for a number of APQ items. Controlling for DIF, response style and demographic variables were related significantly to the factors. (PsycINFO Database Record

Chronic physical health conditions and disability among Canadian school-aged children: a national profile.

OBJECTIVE: The objective of this study was to provide a national health and disability profile of Canadian school-aged children based on the World Health Organization's definitions of health condition and disability that would facilitate international comparisons of child health data. METHODS: Data were used from the National Longitudinal Survey of Children and Youth, a 1994 - 95 population-based sample of 22 831 children. FINDINGS: An estimated total of 30.3% of Canadian children aged 6 to 11 had one or more chronic physical health conditions/impairments, while 3.6% had activity-limiting conditions/impairments. Children living with one parent were significantly more likely to have activity-limiting conditions/impairments than those living with two parents. Children with conditions/impairments, particularly those with activity limitations, were significantly more likely than children without health problems to have experienced mental health conditions and learning disabilities, missed school days, received special education, visited health professionals, been hospitalized, and used prescription medication. CONCLUSION: Important differences were found among children in a number of areas as a function of overall physical health status. The findings emphasize the importance of measuring activity limitations distinctly from chronic conditions and impairments, and, perhaps, of measuring impairments distinctly from chronic conditions, and of comparing children with such health problems to children without health problems in order to obtain a more accurate picture of the impact of health on children's lives. The World Health Organization's distinct definitions of health condition and disability facilitate a dimensional approach for describing child health that can serve to clarify this field of study and improve comparability of data across countries.
