Subjective Perception (subjective + perception)
Selected AbstractsHealth, Healthcare Utilization, and Satisfaction with Service: Barriers and Facilitators for Older Korean AmericansJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 9 2005Yuri Jang PhD The present study assessed predictive models of subjective perception of health, healthcare utilization (hospital visits), and satisfaction with healthcare service using a sample of 230 older Korean Americans. Predisposing characteristics (age, sex, and education), health needs (chronic conditions, functional disability, and number of sick days), and a variety of enabling factors (health insurance, English speaking ability, transportation, living arrangement, trust in Western medicine, and reported experience of disrespect in medical settings) were considered. After controlling for predisposing and need factors, health insurance coverage was found to be a significant enabling factor for hospital visits. Subjective perception of health was found to be significant not only for healthcare utilization, but also for satisfaction with service. A greater likelihood of satisfaction was also observed in individuals with health insurance, better English-speaking ability, and greater trust in Western medical care. The reported experience of disrespect or discrimination in medical settings significantly reduced the odds of satisfaction with service. [source] Frequency and perception of cough severityJOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 2 2001AB Chang Objective: The frequency of the common symptom of cough in children is unknown. The aim of this study was to compare cough frequency and perception of cough severity in children with and without recurrent cough. Methodology: Eighty-four children with (C) and without (NC) recurrent cough were recruited in the same season. Cough frequency (measured with cough-meter) and subjective cough severity (measured on parent-completed and child-completed diary cards on two subjective systems), were compared between the two groups. Results: Cough frequency in C (median 65/day) was significantly higher than in NC (10/day). The correlation between daytime and night-time cough was higher in NC (rs = 0.51, P < 0.00001) than in C (rs = 0.3, P = 0.05). The C group had significantly higher coughs per score than NC, for both subjective methods. Conclusion: Children with recurrent cough have a higher frequency and different pattern of cough than controls enrolled in the same season. Subjective perception of cough severity is dependent on the population studied.

Wargocki First page of article [source] Applied psychometrics in clinical psychiatry: the pharmacopsychometric triangleACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2009P. Bech Objective:, To consider applied psychometrics in psychiatry as a discipline focusing on pharmacopsychology rather than psychopharmacology as illustrated by the pharmacopsychometric triangle. Method:, The pharmacopsychological dimensions of clinically valid effects of drugs (antianxiety, antidepressive, antimanic, and antipsychotic), of clinically unwanted effects of these drugs, and the patients' own subjective perception of the balance between wanted and unwanted effects are analysed using rating scales assessed by modern psychometric tests (item response theory models) Results:, Symptom rating scales fulfilling the item response theory models have been shown to be psychometrically valid outcome scales as their total scores are sufficient statistics for demonstrating dose,response relationship within the various classes of antianxiety, antidepressive, antimanic or antipsychotic drugs. The total scores of side-effect rating scales are, however, not sufficient statistics, implying that each symptom has to be analysed individually. Self-rating scales with very few items appear to be sufficient statistics when measuring the patients' own perception of quality of life. Conclusion:, Applied psychometrics in psychiatry have been found to cover a pharmacopsychometric triangle illustrating the measurements of wanted and unwanted effects of pharmacotherapeutic drugs as well as health-related quality of life. [source] Illness perceptions and quality of life amongst women with pseudotumor cerebriEUROPEAN JOURNAL OF NEUROLOGY, Issue 8 2009A. Kesler Background and purpose:, Pseudotumor cerebri (PTC) is a disorder of increased intracranial pressure without evidence of a space occupying lesion. The purpose of this study was to assess the subjective perception of PTC and its association with stress, anxiety and global quality of life (QOL). Methods:, Fifty-eight women diagnosed with PTC completed questionnaires measuring their subjective appraisal of PTC and specific perceptions of the symptoms, causes, consequences, timeline, controllability and their anxiety, perceived stress, and QOL. Results:, Appraisals of the condition were mostly of loss or threat and those were related to greater anxiety, stress and poorer QOL. Negative perceptions of PTC were related to greater anxiety, stress and poorer QOL. Most of the women attributed their condition to their weight, but adjustment for body mass index ruled out weight as accounting for the findings. Women attributed to the condition symptoms likely to be related to PTC as well as others that seem unrelated. Conclusions:, Our findings underscore the importance of assessing women's subjective perceptions of their condition as a factor related to their levels of anxiety and stress as well as to their QOL. Accurate symptom diagnosis and treatment as well as psychosocial support could assist women who are coping with the burden of this condition and possibly improve their QOL.

[source] Action, inaction, and factors influencing perceived decision makingJOURNAL OF BEHAVIORAL DECISION MAKING, Issue 4 2001Laura Y. Niedermayer Abstract Two studies examined factors hypothesized to be related to the subjective perception of decision making. A total of 302 introductory psychology students read four hypothetical scenarios that varied on two dimensions: frequency of the behavior and whether the behavior was an action or an inaction (a 2 × 2 design). Subjects rated the scenarios on whether the actor made a decision. In Experiment 1, the frequency of behavior was unrelated to decision making. In addition, actions were given higher decision ratings than inactions in two scenarios, but lower ratings in the other two scenarios. In Experiment 2 the latter discrepancy was explained by ratings of whether the actor behaved thoughtfully rather than reflexively, in that these ratings mediated the action,decision rating relationship.

[source] Electric Parameters Optimization in Spinal Cord Stimulation.NEUROMODULATION, Issue 4 2010Study in Conventional Nonrechargeable Systems Background:, Spinal cord stimulation devices provide a means of creating an electric field. The parameters used to produce this electric field are: pulse amplitude, pulse width (Pw), and pulse frequency (F). Aims:, The purpose is to document the effects that the various stimulus parameters have on patient perception of paresthesia and the relationship that this perception has on pain relief. Methods:, Stimulus parameters were varied independently keeping the electrode polarity constant while recording stimulation thresholds. The Pw was varied from 195 to 300 µsec while maintaining the frequency at 50 Hz. The F was varied from 10 to 100 Hz while maintaining the Pw at 300 µsec. We also measured the paresthesia coverage percentage and the subjective perception of quality reported by the patients with each one of the parameter changes. Results:, There was a statistically significant correlation between Pw and all the stimulation thresholds. As for the therapeutic range, the differences observed also were statistically significant. Pw variation did not produce significant differences in coverage and subjective quality of the paresthesia. The perception threshold did not vary significantly with F changes. However, F significantly affected both coverage of the painful area and paresthesia perception quality. Conclusions:, In the usual Pw ranges, it seems that its usefulness is limited to obtaining finer adjustments in the stimulation amplitude. Frequency management may be significantly useful to get a wider coverage of the stimulated area. [source] An analysis on the subjective perception of policy action on peripherality: A comparative assessment in accessible and peripheral areas of six countries of the EU,REGIONAL SCIENCE POLICY AND PRACTICE, Issue 2 2009Joan Noguera peripherality; regional development; policy analysis Abstract The paper presents an analysis of the subjective perception of the policy efficiency on peripherality in 12 regions of six countries of the EU. In each country two regions are selected: one peripheral but relatively dynamic and another accessible but relatively lagging. Public action conditions a range of processes and activities that continuously influence the intensity and direction of development. It can be part of the new factors of territorial development (NFTD) building up or hindering peripherality. The paper has the following aims: to identify what generic types of measures are believed to be more efficient for development; to analyse which measures (spatial or aspatial) are considered more important for development; to rank different NFTD according to preferences of interviewed experts; to identify whether there are differences between accessible and peripheral areas in policy preferences and needs; and to define which influences national contexts. A minimum of 5 experts per study area have been interviewed for this analysis. [source] Patients' Sexual Health: A Qualitative Research Approach on Greek Nurses' PerceptionsTHE JOURNAL OF SEXUAL MEDICINE, Issue 8 2009Evangelia Nakopoulou MSc ABSTRACT Introduction., Health care professionals, especially nurses, through their contact with patients, play an important role in encouraging discussions about sexual concerns. Aim., To explore perceptions on sexual health issues and how these might inhibit or enhance Greek nurses' ability to incorporate sexual health assessment into everyday practice. Main Outcome Measures., A discussion guide was used as checklist to ensure that the basic issues would be addressed. Topics related to the areas of interest were either brought up from the participants or introduced by the moderator. Methods., The study recruited a purposive sample of 44 Greek staff nurses (SN) attending a course leading to their professional upgrading. A qualitative research design was employed using seven focus groups. Discussions started with nurses' perceived definitions of sexual health and proceeded with open-ended questions. Transcripts were analyzed using thematic analysis based on the principles of grounded theory. Results., Three central themes were identified from transcripts' thematic analysis: subjective perception of sexual health, discussing sexual problems, and educational and training needs. Participants' perceptions of sexual health centred mainly on the emotional and somatic dimensions. Regarding clinical practice, a variety of personal and contextual reasons limit nurses' willingness to talk about sexuality with patients, such as gender and age differences, familial upbringing, lack of time and privacy, and restricted perception of nursing role. All nurses stressed the need for further specialized training not only in physiology issues related to sexuality, but also most importantly in communication skills. Conclusions., Although Greek nurses acknowledge the importance of sexual health assessment, they believe that sexual history taking is not within the range of their professional tasks. Since holistic care demands sexual health assessment and intervention to be an integral part of nursing practice, it is necessary to introduce courses in their curriculum and experiential workshops addressing the multidimensionality of sexuality.

Zenico Summary Lepidium meyenii (Maca) is a cultivated root belonging to the brassica family used in the Andean region for its supposed aphrodisiac properties. We carried out a double-blind clinical trial on 50 Caucasian men affected by mild erectile dysfunction (ED), randomised to treatment with Maca dry extract, 2400 mg, or placebo. The treatment effect on ED and subjective well-being was tested administrating before and after 12 weeks the International Index of Erectile Function (IIEF-5) and the Satisfaction Profile (SAT-P). After 12 weeks of treatment, both Maca- and placebo-treated patients experienced a significant increase in IIEF-5 score (P < 0.05 for both). However, patients taking Maca experienced a more significant increase than those taking placebo (1.6 ± 1.1 versus 0.5 ± 0.6, P < 0.001). Both Maca- and placebo-treated subjects experienced a significant improvement in psychological performance-related SAT-P score, but the Maca group higher than that of placebo group (+9 ± 6 versus +6 ± 5, P < 0.05). However, only Maca-treated patients experienced a significant improvement in physical and social performance-related SAT-P score compared with the baseline (+7 ± 6 and +7 ± 6, both P < 0.05). In conclusion, our data support a small but significant effect of Maca supplementation on subjective perception of general and sexual well-being in adult patients with mild ED. [source] Conversion from valproic acid onto topiramate in adolescents and adults with epilepsyACTA NEUROLOGICA SCANDINAVICA, Issue 5 2009A. Schreiner Objective,,, To explore efficacy and tolerability outcomes of topiramate (TPM) in patients with epilepsy transitioning from valproic acid (VPA) because of insufficient efficacy and/or tolerability onto TPM. Methods,,, Multicenter, open label, single arm, non-interventional study examining patients (,12 years) with epilepsy, transitioning onto TPM from baseline mono-or combination therapy with VPA. TPM was added onto the existing antiepileptic drug (AED) treatment and started at a dose of 25 mg once daily. The dose was titrated up with 25 mg/day increments, once every 1,2 weeks, until a final dose between 50,200 mg/day was reached. Based on clinical judgment, the treating physician decided whether or not and when the existing AED treatment especially with VPA could be withdrawn. Documented were type and frequency of seizures, TPM dose, quality of life (QOLIE-10 questionnaire), subjective perception of improvement, and adverse events (AE). Results,,, One hundered and forty-seven patients (59% women, mean age 41 years) switched from baseline VPA treatment onto TPM because of insufficient efficacy (61%) and/or poor tolerability (81%). Average duration of follow-up was 20.3 weeks with an overall discontinuation rate of 16.3% of patients, mainly because of AE (in 8.2% of 147 patients). At study endpoint, the intended shift to TPM monotherapy was achieved in 70% of patients at a median dose of 150 mg/day. A seizure reduction of ,50% was achieved in 75% of patients in the last scheduled period (week 8,20), and 51% of patients entering that period remained seizure-free. Quality of life improved significantly as compared with baseline for all domains of QOLIE-10 (P < 0.001). Most frequent AEs were weight decrease (4.8%), paraesthesia and fatigue (4.1% each), speech disorder and headaches (2.7% each). Conclusions,,, In patients with epilepsy not satisfactorily treated with VPA, conversion to TPM was associated with improved seizure control as well as improvement in several aspects of quality of life. [source] Self-assessment of voice therapy for chronic dysphoniaCLINICAL OTOLARYNGOLOGY, Issue 1 2004R. Speyer Self-assessment of voice therapy for chronic dysphonia The effects of voice therapy in a group of chronically dysphonic patients are determined using two quality-of-life (QOL) instruments: the Voice Handicap Index (VHI), and a simple three-item outcome scale (three visual analogue scales). Both instruments measure changes in the quality of the voice itself and in the extent of impairment resulting from the dysphonia as experienced by the patient in social and occupational settings. Statistical tests conducted on pre- and post-treatment data indicated significant improvements on both instruments for the group as a whole. At the individual level, however, the effects were diverse. For roughly 50% of the subjects, a significant improvement could be established. The positive changes as measured with the three-item scale were greater than those measured with the VHI. The results suggest that the two QOL instruments measure slightly different aspects of the subjective perception of the therapy effects. In order to obtain a general evaluation of the patient's handicap, it may suffice to ask some simple questions. [source] Randomized controlled trial of an instructional DVD for clinical skills teachingEMERGENCY MEDICINE AUSTRALASIA, Issue 3 2007Joon C Lee Abstract Objective:, To determine the efficacy of clinical skills teaching using a DVD-based teaching medium (interventional group) compared with the traditional, four-step, face-to-face approach (control group). The clinical skill selected for the study was that of paediatric intraosseous (IO) needle insertion. Methods:, Thirty-six candidates who had no exposure to IO needle insertion experience within the past 12 months were randomly allocated into two groups. The interventional group (n = 18) was shown a 10 min instructional DVD and then allowed 10 min each to practise IO insertion with a paediatric training mannequin. The control group (n = 18) was given a 20 min, four-step, face-to-face teaching session with practical exposure and individual use of an IO needle on a training mannequin facilitated by an instructor. Each candidate was assessed using a checklist of critical steps for successful IO needle insertion and given a score out of 10. A modified Likert score reflecting candidates' subjective perceptions of the whole experience was completed after the test. Results:, The interventional group obtained a mean score of 7.56 (SD 1.65) and the control teaching group a mean score of 6.00 (SD 1.84). The mean difference was ,1.56 (P < 0.01, 95% CI ,2.74 to ,0.37). There was no difference in the candidates' perception on the satisfaction, anxiety and confidence level about the teaching experience. Conclusion:, The study suggests that the use of instructional DVD for clinical skills teaching results in improved learning outcomes compared with the traditional face-to-face didactic teaching method.

[source] The importance of dental beliefs for the outcome of dental-fear treatmentEUROPEAN JOURNAL OF ORAL SCIENCES, Issue 2 2003Kajsa Henning Abrahamsson This study investigated the importance of dental beliefs and the predictive value of the Dental Belief Survey (DBS) in dental-fear treatment. The sample comprised 117 adult patients seeking treatment at a dental-fear clinic. Pretreatment data were collected during a screening procedure, including two visits to the dentist. Outcome measurements were completed after treatment. The dentist rated successful/unsuccessful treatment outcome. Patients unsuccessful in treatment (n = 48) reported more initial negative dental beliefs, while patients successful in treatment (n = 69) showed a larger decrease in negative beliefs between the first and second visit to the dentist. However, these differences were small. There was a significant difference between the groups at visit two. Thus, patients unsuccessful in treatment reported more negative beliefs about how dentists communicate. Regression analyses showed that improved dental beliefs during the first two visits to the dentist predicted dental-fear reduction, while longer avoidance time, female gender, low engagement in treatment, and depressed mood increased the risk of unsuccessful treatment outcome. Our results suggest that the DBS provides valuable information, and that patients' subjective perceptions about how dentists communicate are important for treatment outcome. However, initial dental beliefs were not found to predict clinical treatment outcome. [source] Quantifying subjective assessment of sleep and life-quality in antidepressant-treated depressed patientsHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 1 2003Andrew G. Mayers Abstract This study sought to establish a method of quantifying subjective perceptions of sleep against perceptions of life-quality and mood, using amended versions of the Pittsburgh sleep diary (PghSD) and quality of life of insomniacs (QOLI) questionnaire. Diaries and questionnaires were self-completed in participants' homes. Outpatients with a DSM-IV diagnosis of major depressive disorder were compared with a healthy control group (with no history, or family history, of depression). Poorer sleepers, as determined by the sleep diary, were significantly more likely to report poorer life-quality and mood perceptions on the subsequent questionnaire. Furthermore, the depressed group reported significantly poorer perceptions of sleep quality and poorer perceptions of life-quality and mood than the control group, even though estimates of sleep disturbance were similar. This may indicate that depressed individuals experience more ,sleep distress' than healthy individuals. These results confirm the extent of subjectively reported sleep disruption in depression and demonstrate the merit of combining the amended PghSD and QOLI to quantify sleep perceptions.

[source] Exploring social capital in rural settlements of an islander region in GreeceJOURNAL OF COMMUNITY & APPLIED SOCIAL PSYCHOLOGY, Issue 2 2010Anastasia Zissi Abstract This paper reports on a large scale cross-sectional study examining subjective perceptions of community social life held by a randomly selected sample of residents (n,=,428) in all small rural settings (n,=,89) of the region of North Aegean Sea. The notion of social capital was used as a conceptual tool in order to explore different aspects of the relational life of contemporary rural communities. This study has two aims: First to provide an account of rural residents' perceptions of village life in terms of interpersonal support, mutual aid, trust, social cohesion and community competence, and second to examine the suitability of the social capital notion within the specific cultural context. A combination of data collection procedures and a range of sources were employed, such as key informants, rural residents and researchers' field observations. The findings indicate that small farming communities of high devotion with deep roots and strong sense of belonging face severe demographic imbalance and experience low civic power given the limited links with external agents. The mainstream notion of social capital as an unconditionally beneficial factor is thus questioned. The findings call for revisiting its relevance across communities with varying capacities and needs. Copyright © 2009 John Wiley & Sons, Ltd. [source] Patient and caregiver quality of life in Huntington's diseaseMOVEMENT DISORDERS, Issue 5 2008Rebecca E. Ready PhD Abstract Little is known about subjective perceptions of quality of life (QOL) in Huntington's disease (HD). The current study determined correlates of patient and caregiver QOL and assessed change over time. Participants were 22 patient-caregiver dyads, who rated QOL at baseline and 6 months later. Overall, patients' functional and cognitive impairment were significantly correlated with patient and caregiver QOL. Neuropsychiatric symptoms had differential impact on patient and caregiver QOL. Furthermore, when patients recalled their QOL about a previous time, their recall may have been negatively biased. Clinical implications of results are discussed. Future work is needed because subjective QOL is an important outcome measure in therapeutic trials. © 2008 Movement Disorder Society [source] A BROAD PERFORMANCE BENCHMARK BASED ON CITIZENS' PREFERENCES: THE CASE OF SWEDISH PUBLIC TRANSPORTATIONANNALS OF PUBLIC AND COOPERATIVE ECONOMICS, Issue 4 2009Magnus Söderberg ABSTRACT,:,Benchmarks have been recommended for assessing the relative performance of local government services. However, these are often narrowly defined and therefore ignore important welfare dimensions. This paper proposes a framework for benchmarking based on a combination of production and cost characteristics and citizens' subjective perceptions. An evaluation consisting of Data Envelopment Analysis (DEA) and different regression models is applied on all 21 Swedish regional public transport authorities, covering the period 2002,2006 (n = 103). The results indicate that the industry as a whole is about 70% efficient and that efficiency can be improved by increasing the sizes of the urban and the bus vehicle-km shares. The optimal ownership structure is to have one large owner combined with about 25 small owners. [source] The role of subjective time in identity regulationAPPLIED COGNITIVE PSYCHOLOGY, Issue 8 2009Anne E. Wilson We explore the function of subjective perceptions of time in regulating personal identity. Events that reflect favourably on the self feel more recent than events that reflect negatively on the self. We propose that this systematic bias in subjective time judgment serves an identity regulation function: These biases allow people to maintain a favourable evaluation of current self. Recent events are likely to be judged as ,belonging' to the current self and thus incorporated into current identity. Distant events are more likely to be viewed as belonging to a former self who is quite distinct from the today's self. Therefore, by perceiving past positive experiences as more recent than negative ones, people are able to continue to take credit for former glories while reducing the threat of past failings on present identity. We discuss evidence for both the motivational account of subjective distancing and its role in regulating and maintaining a desired current identity. Copyright © 2009 John Wiley & Sons, Ltd. [source] The impact of cognitive styles on perceptual distributed multimedia qualityBRITISH JOURNAL OF EDUCATIONAL TECHNOLOGY, Issue 4 2003Gheorghita Ghinea Multimedia technology has been widely used in web-based instruction, but previous studies have indicated that individual differences, especially cognitive styles, have significant effects on users' preferences with respect to presentation of multimedia content. However, such research has thus far neglected to examine the effect of cognitive styles on users' subjective perceptions of multimedia quality. This study aims to examine the relationships among users' cognitive styles, the multimedia Quality of Service (QoS) delivered by the underlying network, and Quality of Perception (QoP), which encompasses user levels of enjoyment and understanding of the informational content provided by multimedia material. Accordingly, 132 users took part in an experiment in which they were shown multimedia video clips presented with different values of two QoS parameters (frame rate and colour depth). Results show that, whilst the two QoS parameters do not impact user QoP, multimedia content and dynamism levels significantly influence the user understanding and enjoyment component of QoP.
