Behavior Rating Inventory of Executive Function in Preschool (BRIEF-P) and Attention-Deficit and Hyperactivity Disorders (ADHD): A Systematic Review and Meta-Analysis of Floor and Ceiling Effects

BACKGROUND

ADHD is a neurodevelopmental disorder that is accompanied by executive challenges.

OBJECTIVES

To obtain evidence of the usefulness of the BRIEF-P and to analyze the possible ceiling and floor effect of its scores in the assessment of executive function in preschoolers with signs compatible with a possible diagnosis of ADHD.

METHOD

A search was performed in Science Direct, NCBI (PubMed), and ProQuest Education Journals during the period 2012-2022. We included studies that evaluated samples of individuals with symptomatology compatible with ADHD, with an age range between 2 and 6 years, published in English or Spanish. Of a total of 2538 articles, only seven met the inclusion criteria. The risk of bias was assessed using the QUADAS-2 questionnaire. The main variables were age and executive functioning.

CONCLUSIONS

Executive deficits in early-age individuals with symptoms compatible with ADHD are more extensive than just deficits in working memory. A floor effect has been found in tests associated with hot executive functions and a ceiling effect in cold executive functions. This makes it necessary to use different tests to assess executive performance in preschoolers with ADHD-compatible symptomatology and to design intervention proposals accordingly. The BRIEF-P is an instrument that facilitates obtaining a sensitive and discriminative executive profile, although it should be used in combination with other neuropsychological performance tests.

Evaluating and Comparing the Correlation and Performance of PROMIS and FAAM ADL in a Foot and Ankle Patient Population

BACKGROUND

There is a paucity of literature assessing 2 of the commonly used static Patient-Reported Outcomes Measurement Information System (PROMIS) forms (PROMIS Global-10 and PROMIS Physical Function Short Form 10a [PF SF 10a]) and the Foot and Ankle Ability Measure Activities of Daily Living (FAAM ADL).

METHODS

The PROMIS Global-10, PROMIS PF SF 10a, and FAAM ADL were compared among new foot and ankle patients. Spearman rho (ρ) correlations were calculated, and ceiling and floor effects were determined.

RESULTS

The FAAM ADL demonstrated strong correlations with PROMIS PF SF 10a, P = .88, 95% confidence interval (CI): 0.86-0.90, P < .001, and PROMIS Global-10 Physical Health (P = .75, 95% CI: 0.71-0.78, p < .001). The FAAM ADL and PROMIS Global-10 Mental Health demonstrated a moderate correlation (P = .41, 95% CI: 0.34-0.47, P < .001). No PROM demonstrated an appreciable floor effect. The PROMIS Global-10 Physical Health demonstrated the lowest ceiling effect (n=11 [1.6%]).

CONCLUSION

Because the PROMIS Global-10 captures physical health adequately, provides mental health insight, and performs as well (if not better), we recommend the PROMIS Global-10 among the PROMs studied.Level of Evidence: Level III.

A decrease in the neuroprotective effects of acute spinal cord decompression according to injury severity: introducing the concept of a ceiling effect

OBJECTIVE

Acute traumatic spinal cord injury (tSCI) is followed by a prolonged period of secondary neuroglial cell death. Neuroprotective interventions, such as surgical spinal cord decompression, aim to mitigate secondary injury. In this study, the authors explore whether the effect size of posttraumatic neuroprotective spinal cord decompression varies with injury severity.

METHODS

Seventy-one adult female Long Evans rats were subjected to a thoracic tSCI using a third-generation spinal contusion device. Moderate and severe tSCI were defined by recorded impact force delivered to the spinal cord. Immediately after injury (< 15 minutes), treatment cohorts underwent either a decompressive durotomy or myelotomy. Functional recovery was documented using the Basso, Beattie, and Bresnahan locomotor scale, and tissue sparing was documented using histological analysis.

RESULTS

Moderate and severe injuries were separated at a cutoff point of 231.8 kdyn peak impact force based on locomotor recovery at 8 weeks after injury. Durotomy improved hindlimb locomotor recovery 8 weeks after moderate trauma (p < 0.01), but not after severe trauma (p > 0.05). Myelotomy led to increased tissue sparing (p < 0.0001) and a significantly higher number of spared motor neurons (p < 0.05) in moderate trauma, but no such effect was noted in severely injured rats (p > 0.05). Within the moderate injury group, myelotomy also resulted in significantly more spared tissue when compared with durotomy-only animals (p < 0.01).

CONCLUSIONS

These results suggest that the neuroprotective effects of surgical spinal cord decompression decrease with increasing injury severity in a rodent tSCI model.

A Three-Way Synergistic Effect of Work on Employee Well-Being: Human Sustainability Perspective

We explored the interaction of the United Nation's sustainable development goals to facilitate human sustainability using occupational health and sustainable HRM perspectives. In Study 1 (n = 246), we assessed the preconditions to empirically confirm the distinctiveness of the dimensions of health harm of work from other study constructs. Subsequently, we tested the hypotheses across two studies (n = 332, Study 2; n = 255, Study 3). In alignment with the ceiling effect of human energy theory, the three-way interaction results across the samples consistently indicate that high supervisory political support (SPS) significantly strengthens the negative interactions of psychological health risk factors and high job tension as adverse working conditions (SDG-8) on working-condition-related well-being as the human sustainability dimension (SDG-3). Similarly, synergistic effects were found of the side effects of work on health, high job tension, and high SPS on well-being in sample 3. We discuss theoretical and future research for human sustainability from occupational health and sustainable HRM perspectives.

Comparison of the Psychometric Properties of the EQ-5D-3L-Y and EQ-5D-5L-Y Instruments in Spanish Children and Adolescents

OBJECTIVES

The study aimed to assess the reliability and validity of EQ-5D-5L-Y and to compare the performance of EQ-5D-5L-Y with EQ-5D-3L-Y in children and adolescents.

METHODS

The Spanish versions of the 3L and 5L of EQ-5D for youths, were administered to children and adolescents from the general population. Feasibility and reliability were determined for the EQ-5D-5L-Y. The EQ-5D-5L-Y and EQ-5D-3L-Y were evaluated in terms of ceiling effects, informativity, and correlations with other generic measurements of health-related quality of life.

RESULTS

A total of 714 healthy children and adolescents (10.7 ± 2.1 years old) from the general population participated in the study. Most of the sample reported full health status. The feasibility and reliability for the EQ-5D-5L-Y were acceptable, but the questionnaire showed a low convergent validity. Absolute informativity (Shannon index) showed a slight increase in all dimensions of the 5L compared with the 3L; nevertheless, there were only statistically significant differences between 5L and 3L in the dimension "feeling worried, sad, or unhappy" and also on the overall system. Relative informativity (Shannon evenness index) showed a decrease in the 5L compared with 3L for all dimensions, except for "looking after myself." Correlations with other health measurements, in both 3L and 5L, showed similar results to those observed in the international EQ-5D-3L-Y validation study.

CONCLUSION

The results show that EQ-5D-5L-Y is feasible, consistent, and reliable, but there are minor differences in the ceiling effect and informativity between the EQ-5D-5L-Y and EQ-5D-3L-Y versions in the general population.

The Depression Anxiety Stress Scale 21: Development and Validation of the Depression Anxiety Stress Scale 8-Item in Psychiatric Patients and the General Public for Easier Mental Health Measurement in a Post COVID-19 World

Despite extensive investigations of the Depression Anxiety Stress Scales-21 (DASS-21) since its development in 1995, its factor structure and other psychometric properties still need to be firmly established, with several calls for revising its item structure. Employing confirmatory factor analysis (CFA), this study examined the factor structure of the DASS-21 and five shortened versions of the DASS-21 among psychiatric patients (N = 168) and the general public (N = 992) during the COVID-19 confinement period in Saudi Arabia. Multigroup CFA, Mann Whitney W test, Spearman's correlation, and coefficient alpha were used to examine the shortened versions of the DASS-21 (DASS-13, DASS-12, DASS-9 (two versions), and DASS-8) for invariance across age and gender groups, discriminant validity, predictive validity, item coverage, and internal consistency, respectively. Compared with the DASS-21, all three-factor structures of the shortened versions expressed good fit, with the DASS-8 demonstrating the best fit and highest item loadings on the corresponding factors in both samples (χ2(16, 15) = 16.5, 67.0; p = 0.420, 0.001; CFI = 1.000, 0.998; TLI = 0.999, 0.997; RMSEA = 0.013, 0.059, SRMR = 0.0186, 0.0203). The DASS-8 expressed configural, metric, and scalar invariance across age and gender groups. Its internal consistency was comparable to other versions (α = 0.94). Strong positive correlations of the DASS-8 and its subscales with the DASS-21 and its subscales (r = 0.97 to 0.81) suggest adequate item coverage and good predictive validity of this version. The DASS-8 and its subscales distinguished the clinical sample from the general public at the same level of significance expressed by the DASS-21 and other shortened versions, supporting its discriminant validity. Neither the DASS-21 nor the shortened versions distinguished patients diagnosed with depression and anxiety from each other or from other psychiatric conditions. The DASS-8 represents a valid short version of the DASS-21, which may be useful in research and clinical practice for quick identification of individuals with potential psychopathologies. Diagnosing depression/anxiety disorders may be further confirmed in a next step by clinician-facilitated examinations. Brevity of the DASS-21 would save time and effort used for filling the questionnaire and support comprehensive assessments by allowing the inclusion of more measures on test batteries.

Good Validity and High Internal Consistency of the Forgotten Joint Score-12 in Patients After Medial Opening Wedge High Tibial Osteotomy

BACKGROUND

The Forgotten Joint Score-12 (FJS-12) was originally developed to assess awareness of an artificial joint. Medial opening wedge high tibial osteotomy (MOWHTO), an alternative surgical method of knee replacement, is a joint-preservation surgery; therefore, joint awareness should be used to evaluate its clinical results. However, FJS-12 has not been validated as a tool to evaluate the postoperative results of MOWHTO. This study aimed to validate FJS-12 in MOWHTO.

METHODS

Patients with bilateral knee surgery, previous knee surgery, flexion contracture >15°, varus alignment >20°, and patients without plate removal surgery were excluded. Finally, 71 knees of 71 patients were analyzed, with a mean follow-up of 34.5 months. The FJS-12 score and Knee Injury and Osteoarthritis Outcome Score (KOOS) were obtained, and the floor and ceiling effect of each score was investigated. Cronbach's α was calculated to determine the internal consistency of FJS-12. Spearman's correlation coefficients between FJS-12 and KOOS were calculated to assess convergent validity.

RESULTS

There were ceiling effects in 3 KOOS subscales (symptoms [25.4%], pain [15.5%], and activities of daily living [25.4%]) but not in FJS-12 (8.5%). No floor effect was noted in any patient-reported outcome measures. The total Cronbach's α was 0.9457 in FJS-12. FJS-12 showed moderate-to-strong positive correlations with all KOOS subscales (r = 0.64-0.72).

CONCLUSION

FJS-12 showed a lower ceiling effect than KOOS and high internal consistency and convergent validity in patients following MOWHTO. With its low ceiling effect, FJS-12 was found to be useful for evaluating patients following MOWHTO.

The Effect of GSM Electromagnetic Field Exposure on the Waking Electroencephalogram: Methodological Influences

Although there is consistent evidence that exposure to radiofrequency electromagnetic fields (RF-EMF) increases the spontaneous resting alpha spectral power of the electroencephalogram (EEG), the reliability of this evidence is uncertain as some studies have also failed to observe this effect. The present study aimed to determine whether the effect of RF-EMF exposure on EEG alpha power depends on whether EEG is derived from eyes open or closed conditions and assessed earlier (<5-min) versus later (>25-min) in the exposure interval. Thirty-six adults participated in three experimental sessions, each involving one exposure: "Sham," "Low," and "High" RF-EMF corresponding to peak spatial specific absorption rates averaged over 10 g of 0, 1, and 2 W/kg, respectively. Resting EEG was recorded at baseline (no exposure), during, and after exposure. Alpha power increase was found to be greater for the eyes open than eyes closed EEG during both the High (P = 0.04) and Low (P = 0.04) RF-EMF exposures. There was also a trend toward it being larger at the end, versus the start of the "High" 30-min exposure (P < 0.01; eyes open condition). This suggests that the use of eyes closed conditions, and insufficient RF-EMF exposure durations, are likely explanations for the failure of some studies to detect an RF-EMF exposure-related increase in alpha power, as such methodological choices decrease signal-to-noise ratios and increase type II error.

What Are the Priming and Ceiling Effects of One Experience Measure on Another?

Patient-reported experience measures have notable ceiling effects which can hinder efforts to learn and improve. This study tested whether an iterative (Guttman-style) satisfaction questionnaire combined with instructions intended to give people agency to critique us primes responses on an ordinal scale and reduces ceiling effects. Among the 161 subjects randomly assigned to complete an iterative satisfaction questionnaire before or after an ordinal scale, there was no difference in mean satisfaction (no priming). The Guttman scale was more normally distributed and had slightly less ceiling effect when compared to the ordinal scale. Iterative satisfaction scales partially mitigate ceiling effects. The absence of priming suggests that attempts to encourage agency and reflection have limited ability to reduce ceiling effects, and alternative approaches should be tested.

Factors Associated With Patient Satisfaction Measured Using a Guttman-Type Scale

Patient experience measures such as satisfaction are increasingly tracked and incentivized. Satisfaction questionnaires have notable ceiling effects that may limit learning and improvement. This study tested a Guttman-type (iterative) Satisfaction Scale (GSS) after a musculoskeletal specialty care visit in the hope that it might reduce the ceiling effect. We measured floor effects, ceiling effects, skewness, and kurtosis of GSS. We also assessed factors independently associated with GSS and the top 2 possible scores. In this cross-sectional study, 164 patients seeing an orthopedic surgeon completed questionnaires measuring (1) a demographics, (2) symptoms of depression, (3) catastrophic thinking in response to nociception, (4) heightened illness concerns, and (5) satisfaction with the visit (GSS). Bivariate and multivariable analyses sought associations of the explanatory variable with total GSS and top 2 scores of GSS. Accounting for potential confounding using multivariable analysis, lower satisfaction was independently associated with greater symptoms of depression (β: -0.03; 95% CI: -0.05 to -0.00; P = .047). The top 2 scores of the GSS were independently associated with women (compared to men: odds ratio [OR]: 2.12, 99% CI: 1.01-4.45, P = .046) and lower level of education (masters' degree compared to high school; OR: 0.16, 95% CI: 004-0.61, P = .007). The GSS had no floor effect, a ceiling effect of 38%, a skewness of -0.08, and a kurtosis of 1.3. The 38% ceiling effect of the iterative (Guttman-style) satisfaction measure is lower than ordinal satisfaction scales, but still undesirably high. Alternative approaches for reducing the ceiling effect of patient experience measures are needed.

Attempts to Limit Censoring in Measures of Patient Satisfaction

Background:

Measures of patient satisfaction are increasingly used to measure patient experience. Most satisfaction measures have notable ceiling effects, which limits our ability to learn from variation among relatively satisfied patients. This study tested a variety of single-question satisfaction measures for their mean overall score, ceiling and floor effect, and data distribution. In addition, we assessed the correlation between satisfaction and psychological factors and assessed how the various methods for measuring satisfaction affected net promoter scores (NPSs).

Methodology:

A total of 212 patients visiting orthopedic offices were enrolled in this randomized controlled trial. Patients were randomized to 1 of 5 newly designed, single-question satisfaction scales: (a) a helpfulness 11-point ordinal scale from 0 to 10, (b) a helpfulness ordinal 11-point scale from 0 to 5 (ie, with 1.5, 2.5, etc), (c) a helpfulness 100-point slider, (d) a satisfaction 11-point ordinal scale from 0 to 10, and (e) a willingness to recommend 11-point ordinal scale from 0 to 10. Additionally, patients completed the 2-item Pain Self-Efficacy Questionnaire (PSEQ-2), 5-item Short Health Anxiety Inventory (SHAI-5) Scale, and Patient-Reported Outcomes Measurement Information System (PROMIS) Depression. We assessed mean and median score, ceiling and floor effect, and skewness and kurtosis for each scale. Spearman’s correlation tests were used to test correlations between satisfaction and psychological status. Finally, we assessed the NPS for the various scales.

Results:

Ceiling effects ranged from 29% to 68%. The 11-point ordinal helpfulness scale from 0 to 10 had the least ceiling effect (29%). All of the scales were asymmetrically distributed, with the 11-point ordinal scale from 0 to 5 having the most Gaussian distribution (skew = 0.64 and kurtosis = 2.3). Satisfaction scores did not correlate with psychological factors: PSEQ-2 (r = 0.04; P = .57), SHAI-5 (r = 0.01; P = .93), and PROMIS Depression (r = −0.04; P = .61). Net promoter scores varied substantially by scale design, with higher scores corresponding with greater ceiling effects.

Conclusions:

Variations in scale types, text anchors, and lead-in statements do not eliminate the ceiling effect of single-question measures of satisfaction with a visit to an orthopedic specialist. Further studies might test other scale designs and labels.

Sex Differences in Episodic Memory Variance

Men as a group have been shown to have larger variances than women in several areas pertaining to both biological and psychological traits, but no investigation has been performed in regard to episodic memory. We conducted an analysis on sex differences in episodic memory variance on 535 studies, representing 962,946 individuals, conducted between 1973 and 2013. Results showed that men had larger variances than women in verbal episodic memory tasks as well as episodic memory tasks having to do with spatial locations. Women, on the other hand, had larger variance than men for tasks involving remembering routes. These effects were for the most part small, and exploratory analyses suggest that they might come about, at least in part, because of measures not sufficiently controlled for ceiling effects. This means that the effects should be interpreted with caution and that further research on sex differences in episodic memory variance is needed.

Measuring hope amongst Tanzanian women who participate in microfinance: An evaluation of the Snyder hope scale

Measuring hope reliably and accurately remains an important research objective, not least in less prosperous settings where 'holding on to hope' may be critically important in the struggle against adverse life conditions. The State Hope Scale was designed for use in the US. Despite reported application in diverse cultures and using translations the scale has not been extensively validated outside US populations. This study contributes to a larger project exploring the measurement of hope and provides a critique of Snyder's scale as used in a Tanzanian female population of 1021 urban microfinance participants. We evaluate the scale's validity through assessment of the empirical distribution of scores, item response profiles, internal consistency and discriminatory ability. Participants mostly scored very high and many reached very near the maximum attainable score. Hardly any endorsed the negative half of the response scale. Several problems are discussed including poor discrimination and strong evidence of acquiescence response bias. We also found little association of the scale scores with hypothesised correlates of hope. Future improvements on the measurement of hope are recommended, especially in studies outside the narrow Western context in which the scale was devised.

Psychometric properties of 12-item self-administered World Health Organization disability assessment schedule 2.0 (WHODAS 2.0) among general population and people with non-acute physical causes of disability - systematic review

OBJECTIVE

WHODAS 2.0 is a unified scale to measuring disability across diseases, countries, and cultures. The objective was to explore the available evidence on the psychometric properties of 12-item self-administered WHODAS 2.0 among a general population and people with non-acute physical causes of disability.

METHODS

Five databases Medline, Embase, Web of Science, Scopus, and PsycINFO were searched for papers related to the validity, reliability, responsiveness, minimal clinically important difference or minimal detectable change of 12-item self-administered WHODAS 2.0. In order to avoid missing any potentially relevant studies, the search clauses were left as generic as possible and the refining search was conducted manually. As the review was focusing on chronic physical disorders and general adult population, major psychiatric diagnoses, acute traumas, other acute conditions (e.g., postpartum or pregnancy), hearing loss, progressive neurological disorders, and age <19 years were excluded. The relevancy of the studies was assessed by two independent reviewers.

RESULTS

The 14 out of 191 observational studies were considered relevant. The sample sizes varied from 80 up to 31,251 participants. Great diversity was observed in the participants' health problems. The Cronbach's alpha was high - up to 0.96. The correlations between WHODAS 2.0 and other disability scales were high. Substantial floor without ceiling effect was reported by two studies. Exploratory factor analysis resulted in a multidimensional structure - up to five factors. The discriminative ability and test-retest reliability of the scale was good.

CONCLUSIONS

It seems, that the 12-item self-administered WHODAS 2.0 is internally consistent and a reliable scale demonstrating overall good correlation with other measures of disability. However, it appears that it is a multidimensional scale and its total score may represent different combinations of several contributing factors. Thus, the 12-item WHODAS 2.0 can be more reliable when creating a person's functional profile formed by the 12 individual item scores instead of a single total sum.IMPLICATIONS FOR REHABILITATIONThe 12-item self-administered WHODAS 2.0 is internally consistent and a reliable scale demonstrating overall good correlation with other measures of disability.It appears that it is a multidimensional scale and its total score may represent different combinations of several contributing factors.The 12-item WHODAS 2.0 can be more reliable when creating a person's functional profile formed by the 12 individual item scores instead of a single total sum.

An Overview and Predictors of Achieving the Postoperative Ceiling Effect of the WOMAC Score Following Total Knee Arthroplasty

BACKGROUND

To describe the ceiling effect for the components of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and identify preoperative independent predictors for patients who achieve maximal scores (ceiling effect) after total knee arthroplasty (TKA).

METHODS

A retrospective cohort of 2589 patients undergoing a primary TKA were identified from an established arthroplasty database. Patient demographics, WOMAC and Short Form 12 (SF-12) scores were collected preoperatively and 1 year postoperatively. Logistic regression analysis was used to identify independent preoperative predictors of patients achieving ceiling scores.

RESULTS

The ceiling effect was 26.8% (n = 695) for the pain score, 6.4% (n = 165) for the function score, and 21.2% (n = 548) for the stiffness score. Lower body mass index (P = .001), absence of gastric ulceration (P = .04), absence of anemia (P = .02), absence of depression (P = .004), and absence of back pain (P < .001) and better preoperative WOMAC pain and SF-12 physical (P = .01) and mental (P < .001) scores were associated with a ceiling WOMAC pain score. Male gender (P = .03), lower body mass index (P = .040), absence of gastric ulceration (P = .004), and absence of back pain (P < .001) and better preoperative SF-12 physical (P = .02) scores were associated with a ceiling WOMAC function score. Male gender (P = .001), absence of back pain (P < .001), and better preoperative WOMAC stiffness score (P = .005) and SF-12 mental (P = .001) scores were associated with a ceiling WOMAC stiffness score.

CONCLUSION

The WOMAC pain and stiffness components demonstrated a high ceiling effect but in contrast the functional score had a low ceiling effect. The absence of back pain was a common predictive factor for all 3 components and had the greatest impact upon the likelihood of achieving a ceiling score.

Reducing ceiling effects in the Working Alliance Inventory-Rehabilitation Dutch Version

Purpose: To reduce ceiling effects on domain scores (Task, Goal, and Bond) of the Working Alliance Inventory (WAI)-Rehabilitation Dutch Version by changing response scales and using Visual Analogue Scales (VASs).Methods: Clients, who had at least three treatment sessions prior, randomly received one of the three versions of the WAI-Rehabilitation Dutch Version, using items with a balanced Likert scale, Positive-Packed Likert scale or VAS. Primary outcome was percentage of ceiling effects in total- and domain scores, secondary outcomes were construct validity and internal consistency of the three versions.Results: One hundred and seventy-six clients randomly received a set of questionnaires (one of the three versions of the WAI-Rehabilitation Dutch Version, Session Rating Scale (SRS) and Helping Alliance Questionnaire (HAQ)-II); 152 participants (mean age 51.5 ± 16.3, 106 women) returned the questionnaires. No ceiling effects were present in the total scores of all versions. Significantly fewer ceiling effects were found in the VAS-Version (Goal: 8.0%, Bond: 7.7%) compared to the original (Goal: 18.0%, Bond: 29.8%) and Positive-Packed Version (Goal: 27.1%, Bond: 29.8%). Spearman's correlations between VAS-Version, SRS and HAQ-II ranged 0.747-0.845.Conclusions: Visual Analogue Scales effectively reduced ceiling effects on domain scores of the WAI-Rehabilitation Dutch Version, while maintaining validity.Implications for RehabilitationVisual Analogue Scales effectively reduced ceiling effects on domain scores of the Working Alliance Inventory-Rehabilitation Dutch Version, while maintaining construct validity.The Working Alliance Inventory version with Visual Analogue Scales can be used in rehabilitation.

Validating the Patient Reported Outcomes Measurement Information System (PROMIS) computerized adaptive tests for upper extremity fracture care

BACKGROUND

Computerized adaptive testing (CAT) for patient-reported outcomes (PROs) is a developing area within orthopedic surgery. Our objective was to validate the Patient Reported Outcomes Measurement Information System (PROMIS) CATs for upper extremity fracture care. We sought to correlate PROMIS with legacy PROs and to investigate floor and ceiling effects.

METHODS

Patients who underwent open reduction and internal fixation of upper extremity trauma were prospectively enrolled. Legacy PROs included the visual analog scale for pain, the Disabilities of the Arm, Shoulder and Hand questionnaire, the University of California-Los Angeles Shoulder Rating Scale, the Mayo Elbow Performance Score, and the 36-Item Short Form Health Survey. PROMIS CATs included Physical Function (PROMIS PF), PROMIS Pain Interference (PROMIS Pain), and PROMIS Upper Extremity (PROMIS UE). Correlations between the PROs were calculated as were the absolute and relative floor and ceiling effect.

RESULTS

The study prospectively enrolled 174 patients with upper extremity trauma. There was moderate to high correlation between PROMIS UE CAT and legacy upper extremity-specific PROs (ρ = 0.42-0.79), and high correlation between the PROMIS PF CAT and the 36-Item Short Form Health Survey Physical Component Summary (ρ = 0.71, P < .001). The visual analog scale for pain, University of California-Los Angeles Shoulder Rating Scale, Constant Score, and Mayo Elbow Score demonstrated a significant absolute ceiling effect (20.5%-23.7%), whereas the PROMIS PF, PROMIS UE, and PROMIS Pain CATs demonstrated no absolute ceiling effect.

CONCLUSION

PROMIS PF, Pain, and UE correlate well with legacy PROs in a upper extremity trauma population, with less absolute floor or ceiling effects. This study provides preliminary evidence for the utility of PROMIS CATs in upper extremity trauma patients.

Use of Diabetes Treatment Satisfaction Questionnaire in Diabetes Care: Importance of Patient-Reported Outcomes

The efficacy of diabetes treatment should not be evaluated solely by HbA1c levels as they should also focus on patient-reported outcomes (PROs), such as patient satisfaction, wellbeing and quality of life. The Diabetes Treatment Satisfaction Questionnaire (DTSQ) has been developed to assess patient satisfaction with diabetes treatment. DTSQ has been translated into more than 100 languages and is widely used in many countries, since it is relatively easy to answer and is used for both patients with and without medical therapy. Novel therapeutic options, such as insulin analogs, incretin-based therapy and sodium-glucose cotransporter 2 (SGLT2) inhibitors, have been shown to improve patient satisfaction using DTSQ for assessments. DTSQ is not only used for comparisons between different medications or treatment strategies, but also can be used to assess the quality of diabetes care in clinical settings. This is important as an improvement in treatment satisfaction may enhance patients’ self-efficacy and adherence to therapy, leading to the achievement of long-term stable glycemic control and reduced risk of diabetic complications. In this review, we summarize the current topics in DTSQ, introducing our own experience, and discuss the role of PROs in diabetes treatment.

Effect of Exercise on Arterial Stiffness: Is There a Ceiling Effect?

BACKGROUND

Whether arterial stiffness (AS) can be improved by regular exercise in healthy individuals remains equivocal according to cross-sectional and longitudinal studies assessing arterial properties at discrete time points. The purpose of the present study was to pinpoint the time course of training-induced adaptations in central AS.

METHODS

Aorta characteristic impedance (Zc) and carotid distensibility (CD) were determined with ultrasonography prior to (week 0) and across 8 weeks (weeks 2, 4, and 8) of supervised endurance training (ET) (3 × 60 minutes cycle ergometry sessions per week), in 9 previously untrained healthy normotensive adults (27 ± 4 years) with no history of cardiovascular disease. Exercise capacity was assessed by maximal oxygen consumption (VO2max) elicited by incremental ergometry.

RESULTS

VO2max increased throughout the ET intervention (+12% from week 0 to week 8, P < 0.001, P for linear trend <0.001). Systolic blood pressure rose with ET (+7% from week 0 to week 8, P = 0.019, P for linear trend <0.001). Aorta Zc augmented from week 0 to week 8 of ET in all individuals (+38%, P = 0.003, P for linear trend = 0.002). CD did not significantly differ among time points (P = 0.196) although a linear decreasing trend was detected (P = 0.016).

CONCLUSIONS

Central AS augments during a conventional ET intervention that effectively enhances aerobic exercise capacity in young individuals. This suggests that normal, healthy elastic arteries are not amendable to improvement unless impairment is present.

Choice of rating scale labels: implication for minimizing patient satisfaction response ceiling effect in telemedicine surveys

BACKGROUND

Lack of response variability is problematic in surveys because of its detrimental effects on sensitivity and consequently reliability of the responses. In satisfaction surveys, this problem is caused by the ceiling effect resulting from high satisfaction ratings. A potential solution strategy is to manipulate the labels of the rating scale to create greater discrimination of responses on the high end of the response continuum. This study examined the effects of a positive-centered scale on the distribution and reliability of telemedicine satisfaction responses in a highly positive respondent population.

MATERIALS AND METHODS

In total, 216 telemedicine participants were randomly assigned to one of three experimental conditions as defined by the form of Likert scale: (1) 5-point Balanced Equal-Interval, (2) 5-point Positive-Packed, and (3) 5-point Positive-Centered Equal-Interval.

RESULTS

Although the study findings were not statistically significant, partially because of sample size, the distribution and internal consistency reliability of responses occurred in the direction hypothesized. Loading the rating scale with more positive labels appears to be a useful strategy for reducing the ceiling effect and increases the discrimination ability of survey responses.

CONCLUSIONS

The current research provides a survey design strategy to minimize ceiling effects. Although the findings provide some evidence suggesting the benefit of using rating scales loaded with positive labels, more research is needed to confirm this, as well as extend it to examine other types of rating scales and the interaction between rating scale formats and respondent characteristics.

High Activity Arthroplasty Score has a lower ceiling effect than standard scores after knee arthroplasty

The tested hypothesis was following: the High Activity Arthroplasty Score has a significant lower ceiling effect than American Knee Society Score and Oxford Knee Score after total knee arthroplasty. One hundred patients operated on for total knee arthroplasty with more than one-year follow-up have been included. The ceiling effect was 53% for the American Knee Society Score, 33% for the Oxford Knee Score, and 0% for the High Activity Arthroplasty Score. High Activity Arthroplasty Score had a significantly lower ceiling effect than American Knee Society Score and Oxford Knee Score. High Activity Arthroplasty Score has the potential to detect more subtle differences in level of function than standard scoring systems among a non-selected total knee arthroplasty population.

Patient-reported measures provide unique insights into motor function after stroke

BACKGROUND AND PURPOSE

Patient-reported outcome measures have been found useful in many disciplines but have received limited evaluation after stroke. The current study investigated the relationship that patient-reported measures have with standard impairment and disability scales after stroke.

METHODS

Patients with motor deficits after stroke were scored on standard assessments including the National Institutes of Health Stroke Scale, modified Rankin Scale, and Fugl-Meyer motor scale, and on 2 patient-reported measures, the hand function domain of the Stroke Impact Scale, which documents difficulty of hand motor usage, and the amount of use portion of the Motor Activity Log, which records amount of arm motor usage.

RESULTS

The 43 participants had mild disability (median modified Rankin Scale=2), moderate motor deficits (Fugl-Meyer motor scale=46 ± 22), and mild cognitive/language deficits. The 2 patient-reported outcome measures, Stroke Impact Scale and Motor Activity Log, were sensitive to the presence of arm motor deficits. Of 21 patients classified as having minimal or no impairment or disability by the National Institutes of Health Stroke Scale or modified Rankin Scale (score of 0-1), 15 (71%) reported difficulty with hand movements by the Stroke Impact Scale score or reduced arm use by the Motor Activity Log score. Furthermore, of 14 patients with a normal examination, 10 (71%) reported difficulty with hand movements or reduction in arm use.

CONCLUSIONS

Patient-reported measures were a unique source of insight into clinical status in the current population. Motor deficits were revealed in a majority of patients classified by standard scales as having minimal or no disability, and in a majority of patients classified as having no deficits.

Measuring well-being rather than the absence of distress symptoms: a comparison of the SF-36 Mental Health subscale and the WHO-Five Well-Being Scale

The health status questionnaire Short-Form 36 (SF-36) includes subscales measuring both physical health and mental health. Psychometrically, the mental health subscale contains a mixture of mental symptoms and psychological well-being items, among other things, to prevent a ceiling effect when used in general population studies. Three of the mental health well-being items are also included in the WHO-Five well-being scale. In a Danish general population study, the mental health subscale was compared psychometrically with the WHO-Five in order to evaluate the ceiling effect. Tests for unidimensionality were used in the psychometric analyses, and the sensitivity of the scales in differentiating between changes in self-reported health over the past year has been tested. The results of the study on 9,542 respondents showed that, although the WHO-Five and the mental health subscale were found to be unidimensional, the WHO-Five had a significantly lower ceiling effect than the mental health subscale. The analysis identified the three depression symptoms in the mental health subscale as responsible for the ceiling effect. The WHO-Five was also found to be significantly superior to the mental health subscale in terms of its sensitivity in differentiating between those persons whose health had deteriorated over the past year and those whose health had not. In conclusion, the WHO-Five, which measures psychological well-being, reflects aspects other than just the absence of depressive symptoms.
