Response scales in auditory perception assessment are critical for capturing the true responses of listeners. Despite its impact on data, response scales have received the least attention in auditory perception assessment. In this study, the usability of visual analogue scales for auditory perception assessment were investigated. Five response scales (a unipolar visual analogue scale–negated to regular, a unipolar visual analogue scale—regular to negated, a bipolar visual analogue scale–positive to negative, a bipolar visual analogue scale—negative to positive, and a unipolar 11-point scale (ISO/TS 15666:2021)) for auditory perception assessment are presented. Music and traffic noise were presented to 60 university students at two different levels, i.e., 45 and 65 dBA, respectively. A web-based experimental design was implemented, and tablet pads were provided to the respondents to record their responses. The unipolar 11-point scale required the longest response time, followed by the two unipolar visual analogue scales and two bipolar visual analogue scales with statistical significance. All response scales used in this study achieved statistical reliability and sensitivity for the auditory perception assessment. Among the five response scales, the bipolar visual analogue scale (negative to positive) ranked first in reliability over repeated measures, exhibited sensitivity in differentiating sound sources, and was preferred by the respondents under the conditions of the present study. None of the respondents preferred the unipolar 11-point scale. The visual analogue scale was favoured over the traditional unipolar 11-point scale by young educated adults in a mobile-based testing environment. Moreover, the bipolar visual analogue scale demonstrated the highest reliability and sensitivity, and it was preferred the most by the respondents. The semantic labelling direction from negated to regular, or from negative to positive, is preferred over its opposite counterpart. Further research is necessary to investigate the use of response scales for the general public including children and the elderly, as well as that of semantic adjectives and their counterparts for auditory perception assessment.

Objectives. We determined the effect of three consecutive days of sub-maximal-intensity mountain biking (4.5 hours per day, ~64 km per day), on the sleep of ten healthy, trained male and female mountain bikers. Methods. The sleep of the mountain bikers was assessed both subjectively (visual analogue scales and sleep questionnaires) and objectively (activity data logger) on each night of mountain biking and for seven nights when they were not cycling (pre-exercise, mean of seven nights). The cyclists’ mood and muscular pain were assessed each night using visual analogue scales. The cyclists slept at home in their normal environment. Results. There was no significant difference between the mountain bikers’ muscular pain and mood (calm/anxious visual analogue scale) measured during the pre-exercise stage and their pain and mood measured on each of the mountain biking nights (p>0.05). However, compared with the pre-exercise stage, the mountain bikers reported that they were significantly more tired (tired/energetic visual analogue scale) on each night of cycling (p<0.01). The sleep of the mountain bikers was disrupted on the night of the third day of mountain biking only. On this night, compared with the pre-exercise stage, the mountain bikers reported that they woke up more during the night (double the number of times) (p<0.001), and an activity data logger recorded that they were awake for about half an hour longer during the night (p<0.05). Conclusion. We have shown that three days of repeated, endurance sub-maximal mountain biking disrupted the sleep of the mountain bikers on the third night of cycling.

This study aimed to investigate the effects of varying midsole hardness on center of pressure (COP) and perceived stability during basketball-specific tasks, as well as the correlation between COP and perception measurements. A total of 20 male basketball players performed 45° cutting and layup while wearing basketball shoes with soft and hard midsoles. COP trajectories were obtained from the Pedar insole system. Stability perceptions at the forefoot and rearfoot were assessed using 150-mm visual analogue scales. Results indicated greater COP mediolateral deviations in soft midsole compared with hard midsole during layup (soft: 16.6 [4.7] mm, hard: 15.8 [4.6] mm, P = .03) but not 45° cutting (soft: 15.7 [5.9] mm, hard: 15.8 [5.6] mm, P = .60). While 16 out of 20 participants preferred soft midsole, no significant difference in visual analogue scale ratings was found between shoes for both tested movements. There was no significant correlation between COP and perceived stability during layup or 45° cutting. In conclusion, midsole hardness of basketball shoes did not consistently affect mediolateral stability of the foot during 45° cutting and layup. Subjective perception alone cannot be used to indicate mediolateral deviation of the foot when executing basketball-specific maneuvers.

Nasal Septoplasty

AbstractObjective:Questionnaires are often used to assess the results of nasal septoplasty, but response rates vary widely. The possible bias caused by non-responders was evaluated to determine the validity of questionnaire results.Methods:Post-operative questionnaires employing visual analogue scales for nasal obstruction were mailed to 182 patients. The 62 non-responders (34.1 per cent) were contacted by telephone, 58 (93.5 per cent) of whom were contactable and responded orally to the questionnaire.Results:Non-responders were younger, but no different from responders with regard to gender, smoking habits or allergies. Post-operative visual analogue scale obstruction scores were slightly, but not statistically, higher in non-responders. However, because non-responders’ pre-operative scores were lower, obstruction scores improved less than in responders. The main reason for not responding was forgetfulness. Some would have preferred an electronic version of the questionnaire.Conclusion:Although post-operative obstruction scores did not differ between the groups, nasal obstruction scores improved more among responders than non-responders. Thus, low response rates may cause bias.

Response scales are widely used to assess the personal experience of sensation and perception in built environments, and have a great impact on the quality of the responses. The purpose of this study was to investigate the effects of response scales on human sensation and perception in moderate indoor environments. Four different response scales were compared under three room temperatures (19.0 °C, 24.5 °C, and 30.0 °C) and five acoustic stimuli (ambient noise, 42 and 61 dBA × water sounds and traffic noise): a bipolar seven-point scale according to ISO 10551:1995, a unipolar 11-point scale according to ISO/TS 15666:2003, these two scales combined for each sensory comfort assessment, and a bipolar visual analogue scale. The degree of relative differentiation based on indoor physical factors made no significant difference across the four response scales. Therefore, the effects of physical factors on human response could be assessed by using any of the four scales tested in this study, with a statistical significance at P < 0.05 in moderate environments. The choice of response scale would depend not only on the type of physical stimulus but also on the question of sensation or perception. The reliability of each response scale was different according to the subjective attributes. The bipolar visual analogue scale was subjectively preferred by the respondents.

Adult Asthmatic

1. Distress ratings for questions relating to the symptoms and impacts of asthma on daily living have been examined in 40 adult asthmatic outpatients. 2. The patients responded to each item in a 76-item questionnaire by marking a 10 cm visual analogue scale to indicate the degree of distress associated with the symptoms or state described in the question. The resulting score (as a percentage of 10 cm) was interpreted as the degree of distress associated with a particular item. 3. The possible influence on these distress scores of five factors, age, duration (time in years from diagnosis to interview), variability [recorded variability of forced expiratory volume in 1 s (FEV1) expressed as amplitude per cent mean], sex and FEV1 (current and worst recorded in the clinic, expressed as per cent of predicted) was investigated. 4. From correlations of each item with age, 11/76 items were significant at P < 0.05. Taking the results from all 76 items in a repeated measures analysis of variance, there was a small significant relationship between age and distress score (P = 0.048). The direction of the association was negative, suggesting that younger patients were less tolerant of asthma; however, the effect of age only explained 1.5% of the total variance in scores of the 76 items. 5. From correlations of visual analogue scale score for each item against duration, 10/76 items were significant at P < 0.05, but taking the 76 items overall there was no significant association (P = 0.2). 6. The remaining factors, sex, variability and FEV1, only showed a significant effect in 1/76, 1/76 and 5/76 items, respectively (P < 0.05). Taking the 76 items overall did not demonstrate significant effects for any of these factors. 7. We conclude that age, sex, FEV1, duration and variability have little influence as predictors of patients' perception of their distress due to asthma.

167 Background: NIVO is the first adjuvant therapy to provide a statistically significant and clinically meaningful improvement in disease-free survival (DFS) versus PBO in resected EC/GEJC following neoadjuvant chemoradiotherapy as demonstrated by CheckMate 577. NIVO was well tolerated with an acceptable safety profile. This analysis provides additional information on the exploratory HRQoL endpoints in this clinical trial. Methods: The effect of NIVO versus PBO on HRQoL, including general and disease-related symptoms, functioning, disease burden, and overall QoL, was assessed using FACT-E and EQ-5D-3L patient-reported outcome (PRO) questionnaires administered at baseline (BL), every 4 weeks during the 12-month treatment period, and at post-treatment follow-up visits (up to 2 years after last dose). Longitudinal change from BL in PRO scores over 12 months was assessed using descriptive statistics. Additionally, mixed model for repeated measures and time to deterioration analyses evaluated the difference between treatment with NIVO and PBO (data not shown). Results: 794 pts with EC/GEJC were randomized 2:1 to NIVO (n = 532) or PBO (n = 262). PRO completion rates were ≥ 95% at BL and ~ 90% at 12 months on treatment. Mean (SD) BL HRQoL scores were similar between treatment arms for the FACT-E total score (NIVO: 133.40 [20.97]; PBO: 134.03 [20.40]); esophageal cancer subscale (ECS; NIVO: 50.2 [9.3]; PBO: 50.1 [8.9]); EQ-5D Visual Analogue Scale (NIVO: 70.4 [22.3]; PBO: 69.1 [24.1]); and EQ-5D Utility Index (NIVO: 0.820 [0.179]; PBO: 0.831 [0.163]) based on the UK value set. Descriptive analyses showed a trend for increases from baseline at most time points through week 49 for both NIVO and PBO treatment groups for FACT-E total score, ECS, and EQ-5D Visual Analogue Scale and Utility Index. Conclusions: Preliminary results from CheckMate 577 demonstrated that pts on NIVO treatment showed trends of improvement in both esophageal-specific and general HRQoL. Similar trends were also observed in pts treated with PBO over 1 year. Pts treated with NIVO did not experience a reduction in HRQoL, further supporting clinical data to demonstrate treatment benefit and tolerability for adjuvant NIVO in pts with resected EC/GEJC.

Background The association of depressive symptoms with health status in peripheral artery disease (PAD) is understudied. No reports of differential impact on women have been described. Methods and Results The PORTRAIT (Patient‐Centered Outcomes Related to Treatment Practices in Peripheral Artery Disease Investigating Trajectories) registry enrolled 1243 patients from vascular specialty clinics with new or worsening PAD symptoms. Depressive symptoms were assessed at baseline and 3 months using the 8‐Item Patient Health Questionnaire (score ≥10 indicating clinically relevant depressive symptoms). Disease‐specific and generic health status were measured by Peripheral Artery Questionnaire and EQ‐5D Visual Analogue Scale at baseline and 3, 6, and 12 months. An adjusted general linear model for repeated measures was constructed for baseline and 3‐, 6‐, and 12‐month health status outcomes by depressive symptoms at baseline. Differences by sex were tested with interaction effects. The mean age was 67.6±9.4 years with 38% (n=470) women. More women than men (21.1% versus 12.9%; P <0.001) presented with severe depressive symptoms. In the adjusted model, patients with depressive symptoms had worse health status at each time point (all P <0.0001). Results were similar for EQ‐5D Visual Analogue Scale scores. The magnitude in 1‐year change in health status scores did not differ by sex. Depressive symptoms explained 19% of the association between sex differences in 1‐year Peripheral Artery Questionnaire summary scores. Conclusions Women with PAD have a high burden of depressive symptoms. Depressive symptoms were associated with a strikingly worse disease‐specific health status recovery path over the year following PAD diagnosis in men and women. Developing and testing interventions to address depressive symptoms in PAD are urgently needed. Registration URL: https://www.clinicaltrials.gov ; Unique identifier: NCT01419080.

This present paper reviews the reliability and validity of visual analogue scales (VAS) in terms of (1) their ability to predict feeding behaviour, (2) their sensitivity to experimental manipulations, and (3) their reproducibility. VAS correlate with, but do not reliably predict, energy intake to the extent that they could be used as a proxy of energy intake. They do predict meal initiation in subjects eating their normal diets in their normal environment. Under laboratory conditions, subjectively rated motivation to eat using VAS is sensitive to experimental manipulations and has been found to be reproducible in relation to those experimental regimens. Other work has found them not to be reproducible in relation to repeated protocols. On balance, it would appear, in as much as it is possible to quantify, that VAS exhibit a good degree of within-subject reliability and validity in that they predict with reasonable certainty, meal initiation and amount eaten, and are sensitive to experimental manipulations. This reliability and validity appears more pronounced under the controlled (but more artificial) conditions of the laboratory where the signal: noise ratio in experiments appears to be elevated relative to real life. It appears that VAS are best used in within-subject, repeated-measures designs where the effect of different treatments can be compared under similar circumstances. They are best used in conjunction with other measures (e.g. feeding behaviour, changes in plasma metabolites) rather than as proxies for these variables. New hand-held electronic appetite rating systems (EARS) have been developed to increase reliability of data capture and decrease investigator workload. Recent studies have compared these with traditional pen and paper (P&P) VAS. The EARS have been found to be sensitive to experimental manipulations and reproducible relative to P&P. However, subjects appear to exhibit a significantly more constrained use of the scale when using the EARS relative to the P&P. For this reason it is recommended that the two techniques are not used interchangeably.
