    Abstract: Management researchers often use consensus-based composition models to examine the antecedents and effects of higher-level constructs. Typically, researchers present three indices, r wg , ICC(1), and ICC(2), to demonstrate agreement and consistency among lower-level units when justifying aggregation. Nevertheless, researchers debate what values for these indices are sufficient. This study examines the distributional characteristics of ICCs and r wg values from three sources: the multilevel literature, a large multinational sample of student teams, and a large sample of randomly generated “pseudo teams.” Our results support existing cutoff criteria for ICCs but suggest that generally accepted values for r wg may, under certain circumstances, reflect pseudo-agreement (i.e., agreement observed among two raters not attributable to the same target). Thus, when there is minimal between-group variance (i.e., low ICCs), it is difficult to determine whether high r wg values reflect agreement or pseudo-agreement. Based on these findings, we provide recommendations to help researchers interpret aggregation indices.

    Abstract: The impact of perioperative risk factors on outcomes following outpatient sinus surgery is well defined; however, risk factors and outcomes following inpatient surgery remain poorly understood. We aimed to define risk factors of postoperative acute respiratory failure following inpatient sinus surgery. Methods: Utilizing data from the Nationwide Inpatient Sample Database from the years 2010 to 2014, we identified patients (≥18 years of age) with an Internal Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) procedure code of sinus surgery. We used multivariable logistic regression to identify risk factors of postoperative acute respiratory failure. Results: We identified 4919 patients with a median age of 53 years. The rate of inpatient postoperative acute respiratory failure was 3.35%. Chronic sinusitis (57.7%) was the most common discharge diagnosis. The final multivariable logistic regression analysis suggested that pneumonia, bleeding disorder, alcohol dependence, nutritional deficiency, heart failure, paranasal fungal infections, and chronic kidney disease were associated with increased odds of acute respiratory failure (all P 〈 .05). Conclusion: To our knowledge, this represents the first study to evaluate potential risk factors of acute respiratory failure following inpatient sinus surgery. Knowledge of these risk factors may be used for risk stratification.

    Abstract: Background/objective. Long-term changes in the motor cortex can be induced by practicing motor tasks with simultaneous application of peripheral nerve stimulation. This combination may augment motor rehabilitation after stroke but has been used primarily during contraction of the affected hand. The authors tested the effect of a right hand movement that electrically stimulated left hand contraction on right motor cortex excitability. Methods. Three tasks were used in 15 healthy subjects—a motor and stimulation task (MS task ), stimulation only task (S task ), and motor only task (M task ). The MS task consisted of isometric thumb abduction of the right hand that triggered paired electrical stimulation of the left abductor pollicis brevis (APB) and first dorsal interosseus (FDI) motor points. The S task was performed 1 week later and matched the stimulation received in the MS task . The M task was performed as a control. Transcranial magnetic stimulation applied to the right motor cortex assessed corticospinal excitability, short latency intracortical inhibition, and intracortical facilitation of the FDI and APB before, immediately after, and 30 minutes after task performance. Results. Corticospinal excitability increased in the FDI and APB following the MS task but not following the S task or M task . The increased excitability present 30 minutes after the MS task also correlated with excitability measures recorded 1 week later. Conclusion. A bilateral motor and electrical stimulation task can drive persistent adaptation within the corticospinal system. Hemiplegic subjects who have poor voluntary movement of the affected hand may be able to contract the unaffected hand to activate and train homologous movements.

    Many Labs 5: Testing Pre-Data-Collection Peer Review as an Intervention to Increase Replicability

    Abstract: Replication studies in psychological science sometimes fail to reproduce prior findings. If these studies use methods that are unfaithful to the original study or ineffective in eliciting the phenomenon of interest, then a failure to replicate may be a failure of the protocol rather than a challenge to the original finding. Formal pre-data-collection peer review by experts may address shortcomings and increase replicability rates. We selected 10 replication studies from the Reproducibility Project: Psychology (RP:P; Open Science Collaboration, 2015) for which the original authors had expressed concerns about the replication designs before data collection; only one of these studies had yielded a statistically significant effect ( p 〈 .05). Commenters suggested that lack of adherence to expert review and low-powered tests were the reasons that most of these RP:P studies failed to replicate the original effects. We revised the replication protocols and received formal peer review prior to conducting new replication studies. We administered the RP:P and revised protocols in multiple laboratories (median number of laboratories per original study = 6.5, range = 3–9; median total sample = 1,279.5, range = 276–3,512) for high-powered tests of each original finding with both protocols. Overall, following the preregistered analysis plan, we found that the revised protocols produced effect sizes similar to those of the RP:P protocols (Δ r = .002 or .014, depending on analytic approach). The median effect size for the revised protocols ( r = .05) was similar to that of the RP:P protocols ( r = .04) and the original RP:P replications ( r = .11), and smaller than that of the original studies ( r = .37). Analysis of the cumulative evidence across the original studies and the corresponding three replication attempts provided very precise estimates of the 10 tested effects and indicated that their effect sizes (median r = .07, range = .00–.15) were 78% smaller, on average, than the original effect sizes (median r = .37, range = .19–.50).

    Abstract: Prior research has indicated that relative to other specialty areas in psychology, counseling psychology researchers are less likely to engage in research activities sponsored by external funding agencies. The primary purposes of this article were to address external funding in the counseling psychology profession and to compare the rates of articles published in the premier counseling psychology research journal ( Journal of Counseling Psychology [ JCP]) that reported external funding to other specialty areas’ premier research journals. Between 2007 and 2011, articles in JCP were less likely than those in other journals to report external funding and less likely to report research designs associated with external sponsorship. Post hoc analyses indicated that articles in a leading vocational research journal also had relatively low rates of external funding, and counseling psychology faculty members were less likely than peers in other programs to report external funding. The implications of these findings for the field are discussed.

    Abstract: Anxiety sensitivity (AS) recently has been identified as a potential cognitive vulnerability underlying substance use problems, with some evidence specifically indicating its relevance to heroin. Focusing on the potential utility of interventions centered on increasing willingness to have anxiety-related sensations reduce vulnerability for relapse following substance use treatment, the current article describes the development of a brief (6 session) behavioral treatment for heightened AS among heroin users. The treatment consists of the following components: (a) psychoeducation about anxiety; (b) interoceptive exposure exercises; and (c) skills-training focused on heightening emotional acceptance, tolerance, and nonevaluative awareness (to facilitate willingness). Preliminary data on this treatment are provided in the form of a case study with a 46-year-old African American man in an inner-city residential substance use treatment facility. Results indicate reductions in AS (especially physical concerns), as well as corresponding decreases in heroin cravings and improvements in emotion regulation.

    Mechanical and Microstructural Properties of Pediatric Anterior Cruciate Ligaments and Autograft Tendons Used for Reconstruction
    SAGE Publications ; 2019

    Abstract: Over the past several decades, there has been a steady increase in pediatric anterior cruciate ligament (ACL) tears, particularly in young female basketball and soccer players. Because allograft tissue for pediatric ACL reconstruction (ACLR) has shown high rates of failure, autograft tissue may be the best option for ACLR in this population. However, differences in the structure and mechanical behavior of these tissues are not clear. Purpose: To characterize the mechanical and microstructural properties in pediatric ACLs and autograft tissues using a rare cadaveric cohort (mean age, 9.2 years). Study Design: Descriptive laboratory study. Methods: ACLs, patellar tendons, quadriceps tendons, semitendinosus tendons, and iliotibial bands (ITBs) were harvested from 5 fresh-frozen pediatric knee specimens (3 male, 2 female) and subjected to a tensile loading protocol. A subset of contralateral tissues was analyzed using bright-field, polarized light, and transmission electron microscopy. Results: Patellar tendons exhibited values for ultimate stress (5.2 ± 3.1 MPa), ultimate strain (35.3% ± 12.5%), and the Young modulus (27.0 ± 8.8 MPa) that were most similar to the ACLs (5.2 ± 2.2 MPa, 31.4% ± 9.9%, and 23.6 ± 15.5 MPa, respectively). Semitendinosus tendons and ITBs were stronger but less compliant than the quadriceps or patellar tendons. ITBs exhibited crimp wavelengths (27.0 ± 2.9 μm) and collagen fibril diameters (67.5 ± 19.5 nm) that were most similar to the ACLs (24.4 ± 3.2 μm and 65.3 ± 19.9 nm, respectively). Conclusion: The mechanical properties of the patellar tendon were almost identical to those of the ACL. The ITB exhibited increased strength and a similar microstructure to the native ACL. These findings are not entirely congruent with studies examining adult tissues. Clinical Relevance: These results can be used to inform further clinical research. In particular, they justify a further examination of the biomechanical and microstructural properties of the ITB in the context of its role as an autograft tissue in pediatric ACL reconstruction.

    Mechanical and Microstructural Properties of Native Pediatric Posterior Cruciate and Collateral Ligaments
    SAGE Publications ; 2019

    Abstract: Although anterior cruciate ligament (ACL) tears have received the most attention, the medial collateral ligament (MCL) is thought to be the most commonly injured knee ligament overall. The lateral collateral ligament (LCL) and posterior collateral ligament (PCL) are less frequently compromised but can be involved in severe multiligament injuries. The paucity of information on the native properties of these ligaments in the pediatric population hinders the overall optimization of treatment for these injuries. Purpose: To characterize the mechanical and microstructural properties of pediatric MCLs, LCLs, and PCLs using a rare cadaveric cohort (mean age, 9.2 years). Study Design: Descriptive laboratory study. Methods: MCLs, LCLs, and PCLs were harvested from 5 fresh-frozen pediatric knee specimens (3 male, 2 female) and were subjected to a tensile loading protocol. A subset of contralateral tissues from a single donor was analyzed using bright-field, polarized light, and transmission electron microscopy to measure collagen fiber morphology. Results: The pediatric MCL exhibited values for ultimate stress (11.7 ± 6.7 MPa), ultimate strain (18.2% ± 6.8%), and the Young modulus (93.7 ± 56.5 MPa) that were similar to values for the LCL (11.4 ± 11.5 MPa, 27.7% ± 12.9%, and 64.4 ± 76.6 MPa, respectively). The PCL demonstrated decreased ultimate stress (4.2 ± 1.8 MPa), increased ultimate strain (28.8% ± 11.9%), and a decreased Young modulus (19.8 ± 10.4 MPa) when compared with the MCL and LCL. All 3 ligaments had similar mean crimp wavelengths (MCL, 32.8 ± 3.6 µm; LCL, 27.2 ± 3.5 µm; PCL, 25.8 ± 3.5 µm) and collagen fibril diameters (MCL, 88.0 ± 26.0 nm; LCL, 93.3 ± 34.6 nm; PCL, 90.9 ± 34.0 nm); however, the fibril distribution profiles exhibited different modalities. Conclusion: The pediatric MCL and LCL possessed similar mechanical properties, while the pediatric PCL was weaker but capable of withstanding higher amounts of strain. All 3 of these pediatric structures were weaker than what has been reported in studies with adult cohorts. Clinical Relevance: Results from this study can be considered preliminary mechanical and microstructural data for healthy pediatric collateral and posterior cruciate ligaments that can be used to guide further laboratory and clinical research.

    Many Labs 2: Investigating Variation in Replicability Across Samples and Settings

    Abstract: We conducted preregistered replications of 28 classic and contemporary published findings, with protocols that were peer reviewed in advance, to examine variation in effect magnitudes across samples and settings. Each protocol was administered to approximately half of 125 samples that comprised 15,305 participants from 36 countries and territories. Using the conventional criterion of statistical significance ( p 〈 .05), we found that 15 (54%) of the replications provided evidence of a statistically significant effect in the same direction as the original finding. With a strict significance criterion ( p 〈 .0001), 14 (50%) of the replications still provided such evidence, a reflection of the extremely high-powered design. Seven (25%) of the replications yielded effect sizes larger than the original ones, and 21 (75%) yielded effect sizes smaller than the original ones. The median comparable Cohen’s ds were 0.60 for the original findings and 0.15 for the replications. The effect sizes were small ( 〈 0.20) in 16 of the replications (57%), and 9 effects (32%) were in the direction opposite the direction of the original effect. Across settings, the Q statistic indicated significant heterogeneity in 11 (39%) of the replication effects, and most of those were among the findings with the largest overall effect sizes; only 1 effect that was near zero in the aggregate showed significant heterogeneity according to this measure. Only 1 effect had a tau value greater than .20, an indication of moderate heterogeneity. Eight others had tau values near or slightly above .10, an indication of slight heterogeneity. Moderation tests indicated that very little heterogeneity was attributable to the order in which the tasks were performed or whether the tasks were administered in lab versus online. Exploratory comparisons revealed little heterogeneity between Western, educated, industrialized, rich, and democratic (WEIRD) cultures and less WEIRD cultures (i.e., cultures with relatively high and low WEIRDness scores, respectively). Cumulatively, variability in the observed effect sizes was attributable more to the effect being studied than to the sample or setting in which it was studied.
