A framework for understanding how midwives perceive and provide care management for pregnancies complicated by gestational diabetes or hypertensive disorders of pregnancy.

BACKGROUND: Both gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP) are common, and each are associated with adverse maternal and perinatal outcomes. Midwives may be the first point of care when these conditions arise. This study evaluated the experiences of midwives when providing care to women and people with pregnancies complicated by GDM or HDP. METHODS: A mixed methods study was completed in Ontario, Canada, using a sequential, explanatory approach. A total of 144 online surveys were completed by midwives, followed by 20 semi-structured interviews that were audio recorded and transcribed verbatim. Survey data were analysed using descriptive statistics. Thematic analysis was used to generate codes from the interview data, which were mapped to the Theoretical Domains Framework (TDF), to elucidate factors that might influence management. RESULTS: Most of the midwives' clinical behaviours relating to GDM or HDP were in keeping with guidelines and regulatory standards set by existing provincial standards. Six theoretical domains from the TDF appeared to influence midwives'care pathway: "Internal influences" included knowledge, skills and beliefs about capabilities; while "external influences" included social/professional role and identity, environmental context, and social influences. Interprofessional collaboration emerged as a significant factor on both the internal and external levels of influence. CONCLUSIONS: We identified barriers and facilitators that may improve the experiences of midwives and clients when GDM or HDP newly arises in a pregnancy, necessitating further consultation or management by another health care provider.

Association of the Cerebro-Placental Ratio With Adverse Outcomes in Pregnancies Affected by Gestational Diabetes Mellitus.

OBJECTIVES: Cerebro-placental ratio (CPR) is a doppler tool contributes to clinical decision-making in pregnancies affected by small for gestational age weight (SGA). Pregnancies affected by gestational diabetes mellitus (GDM) tend to have higher newborn weight, but greater risk of adverse perinatal outcomes. We hypothesized that in GDM-complicated-pregnancies CPR will be associated with adverse perinatal outcomes even in the absence of SGA. METHODS: This prospective single-center cohort study included non-anomalous singleton pregnancies in women with GDM. Those with pre-pregnancy diabetes mellitus, hypertensive disorder or suspected SGA were excluded. Routine fetal sonographic assessment included CPR-defined as middle cerebral artery pulsatilty index/umbilical artery pulsatilty index. Masked CPR measurement closest to birth was used, classified as >10th (normal) or ≤10th centile (low). Primary outcome was a composite, consisting of stillbirth, Caesarean birth due to abnormal fetal heart rate pattern, 5-minute Apgar <7, cord arterial pH < 7.0, hypoxic ischemic encephalopathy, or NICU admission >24 hours. RESULTS: Of 281 participants, 24 (8.5%) had low CPR, at a mean gestational age of 36.3 weeks (IQR 34.0-37.4). Birthweight percentile was significantly lower among the low CPR group (35th [IQR 16-31] versus 60th [IQR 31-82]; P = .002). There was no statistically difference in the primary composite outcome between the groups (8.3% versus 7.0%, P = .68). Low CPR was significantly associated with a higher risk of neonatal hypoglycemia (adjusted odds ratio 3.2, 95% CI 1.2-8.3). CONCLUSION: In pregnancies affected by GDM, CPR ≤10th percentile was not associated with adverse perinatal outcome but was associated with neonatal hypoglycemia.

Midwives perceptions of managing pregnancies complicated by obesity: A mixed methods study.

OBJECTIVE: The growing prevalence of obesity is a concern for midwives. In Canada, the absence of regulatory standards, varying protocols and consultant preferences shape clinical decision making for the midwife and may lead to inconsistent practice. Our aim was to understand the barriers, enablers, and knowledge gaps that influenced experiences of midwives in Ontario, Canada when providing care to clients impacted by obesity. METHODS: Mixed methods design using a sequential, explanatory approach. Surveys conducted with midwives were administered using an online platform, followed by semi-structured interviews to understand the perspectives elicited in the survey in greater detail. Interviews were audio recorded and transcribed verbatim. Survey data were analyzed using descriptive statistics, and thematic analysis was used for generating codes, categories and themes from the interview data. RESULTS: 144 midwives completed the survey and 20 participated in an interview. The participants described their clinical management when caring for those with obesity which included considerations regarding additional tests/investigations, consultation and transfer of care, and place of birth. Up to 93% of surveyed midwives believed that clients with obesity were appropriate for midwifery-led care however there was less certainty about suitability as BMI increased to higher ranges such as > 45). The care management was influenced by beliefs and attitudes, knowledge, and system-level factors. Midwives experienced barriers such as inconsistent practices and role confusion, and felt ill equipped to care for pregnancies affected by obesity due to unclear guidelines. CONCLUSIONS: Overall, midwives believe clients with obesity are suitable for midwifery-led care due to its individualized, non-judgmental approach to care. Additional training for midwives and other obstetric care providers would be beneficial to help overcome barriers in providing effective care to pregnancies affected by obesity.

Incidence and Age- and Sex-Specific Differences in the Clinical Presentation of Children and Adolescents With Avoidant Restrictive Food Intake Disorder.

Importance: To our knowledge, this is the first pediatric surveillance study of children and adolescents with avoidant restrictive food intake disorder (ARFID). Objectives: To examine the incidence and age- and sex-specific differences in the clinical presentation of ARFID in children and adolescents in Canada. Design, Setting, and Participants: In this cross-sectional study, patients with ARFID were identified through the Canadian Paediatric Surveillance Program by surveying 2700 Canadian pediatricians monthly from January 1, 2016, to December 31, 2017. Main Outcomes and Measures: The incidence of ARFID in Canadian children (5-18 years of age) and age- and sex-specific clinical characteristics at presentation. Results: In total, 207 children and adolescents (mean [SD] age, 13.1 [3.2] years; 127 [61.4%] female) were included in this study. The incidence of ARFID in children 5 to 18 years of age was 2.02 (95% CI, 1.76-2.31) per 100 000 patients. Older children and adolescents were more likely to endorse eating too little (5-9 years of age: 76.7%; 95% CI, 58%-88.6; 10-14 years of age: 90.9%; 95% CI, 84.6%-94.8%; 15-18 years of age: 95.6%; 95% CI, 83.6%-98.9%; P = .02), have a loss of appetite (5-9 years of age: 53.3%; 95% CI, 35.4%-70.4%; 10-14 years of age: 74.2%; 95% CI, 66.0%-81.0%; 15-18 years of age: 80.0%; 95% CI, 65.5%-89.4%; P = .03), be medically compromised (mean body mass index z score: 10-14 vs 5-9 years of age: -1.31; 95% CI, -2.0 to -0.6; 15-18 vs 5-9 years of age: -1.35; 95% CI, -2.2 to -0.5; 15-18 vs 10-14 years of age: -0.04; 95% CI, -0.6 to 0.5; P < .001; mean percentage of treatment goal weight: 10-14 vs 5-9 years of age: -8.6; 95% CI, -14.3 to -2.9; 15-18 vs 5-9 years of age: -9.8; 95% CI, -16.3 to -3.3; 15-18 vs 10-14 years of age: -1.2; 95% CI, -5.8 to 3.4; P < .001; mean heart rate (beats per min): 10-14 vs 5-9 years of age: -10; 95% CI, -21.9 to 1.9; 15-18 vs 5-9 years of age: -19.7; 95% CI, -33.1 to -6.2; 15-18 vs 10-14 years of age: -9.7; 95% CI, -18.7 to -0.7; P = .002), have higher rates of anxiety (5-9 years of age: 26.7%; 95% CI, 13.7-45.4; 10-14 years of age: 52.3%; 95% CI, 43.7%-60.7%; 15-18 years of age: 53.3%; 95% CI, 38.6%-67.5%; P = .03) and depression (5-9 years of age: 0%; 10-14 years of age: 6.8%; 95% CI, 3.6%-12.7%; 15-18 years of age: 26.7%; 95% CI, 15.7%-41.6%; P < .001), and be more likely to be hospitalized (5-9 years of age: 13.3%; 95% CI, 5.0%-31.1%; 10-14 years of age: 41.7%; 95% CI, 33.5%-50.3%; 15-18 years of age: 55.6%; 95% CI, 40.7%-69.5%; P = .001). Younger children were more likely to endorse lack of interest in food (5-9 years of age: 56.7%; 95% CI, 38.4%-73.2%; 10-14 years of age: 75.0%; 95% CI, 66.8%-81.7%; 15-18 years of age: 57.8%; 95% CI, 42.8%-71.4%; P = .03), avoidance of certain foods (5-9 years of age: 90.0%; 95% CI, 72.6%-96.8%; 10-14 years of age: 69.7%; 95% CI, 61.3%-77.0%; 15-18 years of age: 62.2%; 95% CI, 47.2%-75.3%; P = .03), and refusal based on sensory characteristics (5-9 years of age: 66.7%; 95% CI, 47.9%-81.3%; 10-14 years of age: 38.6%; 95% CI, 30.7%-47.3%; 15-18 years of age: 22.2%; 95% CI, 12.3%-36.9%; P < .001). Eating but not enough was more common in girls (75.0%; 95% CI, 64.1%-83.4%) vs boys (68.5%; 95% CI, 59.8%-76.1; P = .04), and boys had a higher rate of refusal based on sensory characteristics (51.2%; 95% CI, 40.2%-62.2%) compared with girls (31.5%; 95% CI, 23.9%-40.2%; P = .007). Conclusions and Relevance: This study suggests that ARFID is a relatively common eating disorder and is associated with important age- and sex- specific clinical characteristics that may help in early recognition and timely treatment of the presenting symptoms.

Changes in rate of preterm birth and adverse pregnancy outcomes attributed to preeclampsia after introduction of a refined definition of preeclampsia: A population-based study.

INTRODUCTION: Since 2013, various guidelines for hypertension in pregnancy have been refined, no longer requiring proteinuria as a requisite criterion for preeclampsia. We aimed to evaluate the impact of the new definition on preterm birth (PTB) and adverse pregnancy outcomes. MATERIAL AND METHODS: Women delivering in Ontario between April 2012 and November 2016 were included. Delivery <24+0/7 weeks, major fetal anomalies or preexisting renal disease were excluded. The primary outcome was livebirth <37, <34 or <32 weeks. Rates, adjusted rate ratios (aRR) and ratio of the rate ratio (RRR) were used to compare outcomes in the 2 years after the new Society of Obstetricians and Gynaecologists of Canada (SOGC) guideline (December 2014-November 2016; period 2) vs the 2 years before (April 2012-March 2014; period 1), among women with and without preeclampsia. RESULTS: In all, 268 543 and 267 964 births in periods 1 & 2, respectively, were included. Respective preeclampsia rates increased significantly from 3.9% to 4.4% (p < 0.001), with no change in maternal morbidity rates. In preeclamptic women, respective rates of PTB <37 weeks were 21.0% and 20.7% (aRR 1.01, 95% confidence interval [CI] 1.00-1.02), with significant aRR for PTB <34 (0.86, 95% CI 0.77-0.96) and <32 weeks (0.79, 95% CI 0.67-0.94). A similar aRR was observed in women without preeclampsia. In preeclamptic women, composite severe neonatal morbidity decreased after guideline change (aRR 0.95, 95% CI 0.91-0.99), a finding not observed in women without preeclampsia (RRR 0.95, 95% CI 0.91-0.99). CONCLUSIONS: The new definition of preeclampsia was associated with increased disease rates, a modest reduction in adverse neonatal outcomes and no change in maternal outcomes.

Impact of diabetes, obesity and hypertension on preterm birth: Population-based study.

OBJECTIVE: To determine the impact of pre-pregnancy diabetes mellitus (D), obesity (O) and chronic hypertension (H) on preterm birth (PTB). METHODS: Retrospective population-based cohort study in Ontario, Canada between 2012-2016. Women who had a singleton livebirth or stillbirth at > 20 weeks gestation were included in the cohort. Exposures of interest were D, O and H, individually, and in various combinations. The primary outcome was PTB at 241/7 to 366/7 weeks. PTB was further analyzed by spontaneous or provider-initiated, early (< 34 weeks) or late (34-37 weeks), and the co-presence of preeclampsia, large for gestational age (LGA), and small for gestational age (SGA). Multivariable Poisson regression models with robust error variance were used to generate relative risks (RR), further adjusted for maternal age and parity (aRR). Population attributable fractions (PAF) were calculated for each of the outcomes by exposure state. RESULTS: 506,483 women were eligible for analysis. 30,139 pregnancies (6.0%) were complicated by PTB < 37 weeks, of which 7375 (24.5%) had D or O or H. Relative to women without D or O or H, the aRR for PTB < 37 weeks was higher for D (3.51; 95% CI 3.26-3.78) and H (3.81; 95% CI 3.55-4.10) than O (1.14; 95% CI 1.10-1.17). The combined state of DH was associated with a significantly higher aRR of PTB < 37 weeks (6.34; 95% CI 5.14-7.80) and < 34 weeks (aRR 10.33, 95% CI 6.96-15.33) than D alone. The risk of provider initiated PTB was generally higher than that for spontaneous PTB. Pre-pregnancy hypertension was associated with the highest risk for PTB with preeclampsia (aRR 45.42, 95% CI 39.69-51.99) and PTB with SGA (aRR 9.78, 95% CI 7.81-12.26) while pre-pregnancy diabetes was associated with increased risk for PTB with LGA (aRR 28.85, 95% CI 24.65-33.76). CONCLUSION: Combinations of DOH significantly magnify the risk of PTB, especially provider initiated PTB, and PTB with altered fetal growth or preeclampsia.

Gestational weight gain counselling practices among different antenatal health care providers: a qualitative grounded theory study.

BACKGROUND: Inappropriate gestational weight gain in pregnancy may negatively impact health outcomes for mothers and babies. While optimal gestational weight gain is often not acheived, effective counselling by antenatal health care providers is recommended. It is not known if gestational weight gain counselling practices differ by type of antenatal health care provider, namely, family physicians, midwives and obstetricians, and what barriers impede the delivery of such counselling. The objective of this study was to understand the counselling of family physicians, midwives and obstetricians in Ontario and what factors act as barriers and enablers to the provision of counselling about GWG. METHODS: Semi-structured interviews were conducted with seven family physicians, six midwives and five obstetricians in Ontario, Canada, where pregnancy care is universally covered. Convenience and purposive sampling techniques were employed. A grounded theory approach was used for data analysis. Codes, categories and themes were generated using NVIVO software. RESULTS: Providers reported that they offered gestational weight gain counselling to all patients early in pregnancy. Counselling topics included gestational weight gain targets, nutrition & exercise, gestational diabetes prevention, while dispelling misconceptions about gestational weight gain. Most do not routinely address the adverse outcomes linked to gestational weight gain, or daily caloric intake goals for pregnancy. The health care providers all faced similar barriers to counselling including patient attitudes, social and cultural issues, and accessibility of resources. Patient enthusiasm and access to a dietician motivated health care providers to provide more in-depth gestational weight gain counselling. CONCLUSION: Reported gestational weight gain counselling practices were similar between midwives, obstetricians and family physicians. Antenatal knowledge translation tools for patients and health care providers are needed, and would seem to be suitable for use across all three types of health care provider specialties.

Weight gain during pregnancy: Does the antenatal care provider make a difference? A retrospective cohort study.

BACKGROUND: The primary aim of this study was to examine weight gain during pregnancy and associated adverse outcomes across different types of antenatal health care providers. Our research question examined whether type of antenatal health care provider (family physician, obstetrician, midwife, or family physician plus obstetrician) was associated with differing rates of excess or inadequate weight gain and associated adverse outcomes including being large for gestational age, being small for gestational age, cesarean delivery and preterm birth. METHODS: This retrospective cohort study used data from the Better Outcomes Registry & Network Information System, 2014-2016, for singleton hospital births at 20-42 weeks' gestation in Ontario. We calculated descriptive statistics to summarize patient characteristics and outcomes by antenatal health care provider. We calculated crude and adjusted relative risks with 95% confidence intervals (CIs) for the exposure (weight gain during pregnancy) relative to each secondary outcome by health care provider. We calculated population attributable fractions with 95% CIs to assess the proportion of secondary outcomes that could be prevented if inadequate or excess weight gain (according to the 2009 Institute of Medicine guidelines) were removed by health care provider. RESULTS: The final cohort consisted of 231 697 pregnancies, of which 26 043 (11.2%), 136 994 (59.1%), 32 262 (13.9%) and 36 298 (15.7%) were managed by a family physician, obstetrician, midwife, and family physician plus obstetrician, respectively. Rates of weight gain below, within or above recommended levels were 31 742 (13.7%), 71 826 (31.0%) and 128 128 (55.3%), respectively, and did not differ across health care provider groups. No difference was observed in rates of secondary outcomes according to weight gain across health care providers. Excess weight gain was associated with a significant risk of being large for gestational age and cesarean delivery, and inadequate weight gain was associated with an increased risk of being small for gestational age and preterm birth. The population attributable fractions indicated a pronounced contribution of excess weight gain to being large for gestational age across all health care provider groups. INTERPRETATION: Weight gain during pregnancy and rates of associated secondary outcomes did not differ according to antenatal health care provider. This suggests a need for further research exploring counselling techniques and strategies for all types of antenatal health care providers to use in order to promote optimal weight gain during pregnancy.

Prevalence of Pre-Pregnancy Diabetes, Obesity, and Hypertension in Canada.

OBJECTIVE: Pre-existing diabetes mellitus (D), obesity (O), and chronic hypertension (H) can each alter the natural course of pregnancy, especially when they cluster together. Because the prevalence of various combinations of D, O, and H is unknown, the current study was undertaken. METHODS: This population-based cross-sectional study included 506 483 singleton and twin live birth and stillbirth deliveries in Ontario, occurring at ≥20 weeks gestation. All hospital births from 2012 to 2016 were identified in the Better Outcomes Registry and Network information system. The prevalence per 1000 births (95% confidence interval [CI]) of D, O, and H and their combinations were calculated. Prevalence estimates were stratified by twin and singleton gestations, maternal age, parity, and ethnicity (Canadian Task Force Classification II-2). RESULTS: During the study period, 5493 women (10.8 per 1000 births; 95% CI 10.6-11.1) had D, 90,177 (178.2; 95% CI 177.0-179.3) had O, and 5667 (11.2; 95% CI 10.9-11.5) had H. The prevalence per 1000 of DO was 4.8, DH 1.0, and OH 5.5, whereas 359 women (0.71 per 1000) had all three. D and H each linearly increased with rising maternal age, along with their combinations, and to some degree with higher parity. The combination of O and H was highest among women of Black ancestry (14.5 per 1000) and lowest among those of Asian ancestry (3.0 per 1000). CONCLUSION: D, O, and H are common conditions in pregnancy, both alone and in various combinations. These data can be used to assess the impact of each state on perinatal health.

De novo and rare inherited copy-number variations in the hemiplegic form of cerebral palsy.

PurposeHemiplegia is a subtype of cerebral palsy (CP) in which one side of the body is affected. Our earlier study of unselected children with CP demonstrated de novo and clinically relevant rare inherited genomic copy-number variations (CNVs) in 9.6% of participants. Here, we examined the prevalence and types of CNVs specifically in hemiplegic CP.MethodsWe genotyped 97 unrelated probands with hemiplegic CP and their parents. We compared their CNVs to those of 10,851 population controls, in order to identify rare CNVs (<0.1% frequency) that might be relevant to CP. We also sequenced exomes of "CNV-positive" trios.ResultsWe detected de novo CNVs and/or sex chromosome abnormalities in 7/97 (7.2%) of probands, impacting important developmental genes such as GRIK2, LAMA1, DMD, PTPRM, and DIP2C. In 18/97 individuals (18.6%), rare inherited CNVs were found, affecting loci associated with known genomic disorders (17p12, 22q11.21) or involving genes linked to neurodevelopmental disorders.ConclusionWe found an increased rate of de novo CNVs in the hemiplegic CP subtype (7.2%) compared to controls (1%). This result is similar to that for an unselected CP group. Combined with rare inherited CNVs, the genomic data impacts the understanding of the potential etiology of hemiplegic CP in 23/97 (23.7%) of participants.

From questions to answers: Examining the role of pediatric surveillance units in eating disorder research.

Pediatric Surveillance Units (PSUs) provide a unique model for the study of pediatric eating disorders (EDs). Australia, Britain, and Canada have surveillance programs that have generated valuable epidemiological and clinical data on early-onset eating disorders (EOED). The PSUs represent an important collaborative tool that has helped shape our understanding of EOEDs and offers potential to contribute to decisions regarding health resource allocation and public health policy. This paper reviews the role of PSUs as a unique model to study pediatric EDs and its success in translating the knowledge generated by these programs into improving the health of children and adolescents with EDs worldwide.

Working Memory Training in ADHD: Controlling for Engagement, Motivation, and Expectancy of Improvement (Pilot Study).

OBJECTIVE: The aim of this study was to evaluate whether a shortened-length session of CogMed Working Memory Training (CWMT) would be a suitable active control group and evaluate study protocol to aid in design refinements for a larger randomized controlled trial (RCT). METHOD: Thirty-eight post-secondary students diagnosed with ADHD were randomized into 25 sessions of standard (45 min/session) or shortened (15 min/session) CWMT, or into a waitlist control group. RESULTS: There was no significant difference in completion rate or training index score between the standard- and shortened-length groups indicating that both groups showed improvement and put forth good effort during training. CONCLUSION: Preliminary findings suggest that shorter training sessions may induce similar levels of engagement, motivation, and expectancy of improvement in participants. We conclude that a larger scale RCT that utilizes shortened-length training as an active control group is warranted, but that a few modifications to the study protocol will be required.

Symptom Manifestation and Impairments in College Students With ADHD.

To better understand the nature of impairment resulting from attention-deficit/hyperactivity disorder (ADHD) for students in a post-secondary education (PSE) setting, the authors analyzed the symptoms and associated impairment of 135 students with a diagnosis of ADHD who were recruited via Student Disability Services in Canadian post-secondary institutions. The authors (a) developed a novel semistructured telephone interview based on the 6-item Adult ADHD Self-Report Scale Screener-Telephone Interview With Probes (ASRS-TIPS) to elicit students' descriptions of their behavior for each symptom they endorsed, (b) administered standardized tests of executive functioning (EF) and academic fluency, and (c) obtained self-reports of grade point averages (GPAs), EF, cognitive failures, psychopathology, distress, and resilience. Qualitative analysis of the ASRS-TIPS revealed significant impairment relating to symptoms of ADHD in the PSE setting. Students reported clinically significant symptoms of ADHD, psychological distress, and impairment in EF (67%, severe range) and cognitive failure (62%, atypical range) in everyday life. By contrast, their GPAs and standardized scores of EF and academic fluency were in the average range. Standardized scores and GPAs did not capture the impairment that participants experienced in their PSE settings. The ASRS-TIPS may provide a useful tool to help document how these students' symptoms impair functioning in the PSE setting.

Working Memory Training in Post-Secondary Students with ADHD: A Randomized Controlled Study.

OBJECTIVES: To determine whether standard-length computerized training enhances working memory (WM), transfers to other cognitive domains and shows sustained effects, when controlling for motivation, engagement, and expectancy. METHODS: 97 post-secondary students (59.8% female) aged 18-35 years with Attention-Deficit/Hyperactivity Disorder, were randomized into standard-length adaptive Cogmed WM training (CWMT; 45-min/session), a shortened-length adaptive version of CWMT (15 min/session) that controlled for motivation, engagement and expectancy of change, or into a no training group (waitlist-control group). All three groups received weekly telephone calls from trained coaches, who supervised the CWMT and were independent from the research team. All were evaluated before and 3 weeks post-training; those in the two CWMT groups were also assessed 3 months post-training. Untrained outcome measures of WM included the WAIS-IV Digit Span (auditory-verbal WM), CANTAB Spatial Span (visual-spatial WM) and WRAML Finger Windows (visual-spatial WM). Transfer-of-training effects included measures of short-term memory, cognitive speed, math and reading fluency, complex reasoning, and ADHD symptoms. RESULTS: Performance on 5/7 criterion measures indicated that shortened-length CWMT conferred as much benefit on WM performance as did standard-length training, with both CWMT groups improving more than the waitlist-control group. Only 2 of these findings remained robust after correcting for multiple comparisons. Follow-up analyses revealed that post-training improvements on WM performance were maintained for at least three months. There was no evidence of any transfer effects but the standard-length group showed improvement in task-specific strategy use. CONCLUSIONS: This study failed to find robust evidence of benefits of standard-length CWMT for improving WM in college students with ADHD and the overall pattern of findings raise questions about the specificity of training effects. TRIAL REGISTRATION: ClinicalTrials.gov NCT01657721.

The Adult ADHD Self-Report Scale (ASRS): utility in college students with attention-deficit/hyperactivity disorder.

Background. The number of students with Attention Deficit/Hyperactivity Disorder (ADHD) enrolled in colleges and universities has increased markedly over the past few decades, giving rise to questions about how best to document symptoms and impairment in the post-secondary setting. The aim of the present study was to investigate the utility and psychometric properties of a widely-used rating scale for adults with ADHD, the Adult ADHD Self-Report Scale (ASRS-V1.1), in a sample of post-secondary students with ADHD. Methods. A total of 135 college students (mean age = 24, 42% males) with ADHD were recruited from Student Disability Services in post-secondary institutions. We compared informant responses on the ASRS administered via different modalities. First, students' self-report was ascertained using the ASRS Screener administered via telephone interview, in which they were asked to provide real-life examples of behavior for each of the six items. Next, students self-reported symptoms on the 18-item paper version of the ASRS Symptom Checklist administered about 1-2 weeks later, and a collateral report using an online version of the 18-item ASRS Symptom Checklist. Students also completed self-report measures of everyday cognitive failure (CFQ) and executive functioning (BDEFS). Results. Results revealed moderate to good congruency between the 18-item ASRS-Self and ASRS-Collateral reports (correlation = .47), and between student self-report on the 6-item telephone-based and paper versions of the ASRS, with the paper version administered two weeks later (correlation = .66). The full ASRS self-report was related to impairment, such as in executive functioning (correlation = .63) and everyday cognitive failure (correlation = .74). Executive functioning was the only significant predictor of ASRS total scores. Discussion. Current findings suggest that the ASRS provides an easy-to-use, reliable, and cost-effective approach for gathering information about current symptoms of ADHD in college and university students. Collateral reports were moderately related to self-reports, although we note the difficulty in obtaining informant reports for this population. Use of a telephone interview to elicit behavioral descriptions for each item may be useful in future research that is required to specifically test the utility of the ASRS in, for example, documenting and confirming current reports of impairment due to ADHD symptoms and its positive and negative predictive power for diagnosis.
