Evaluating salespeoples' performance is an important task for sales managers. However, little is known about what bases are used by sales managers to evaluate the performance of their salespeople. A study was conducted to determine the bases actually used by sales managers and the results were compared with a study conducted in 1983. Findings indicate more emphasis on profit and cost control, a continued reliance on qualitative measures, and a wide variety of bases being utilized to evaluate the performance of salespeople. Furthermore, the stability of results, across a wide variety of respondent job titles as well as business types and sizes, indicates a good deal of generalizability to other firms.  相似文献

Among individuals with rheumatoid arthritis (RA), stress-associated disease flare can severely impact well-being. Psychological factors such as personal mastery may buffer an individual from the negative effects of those flares. We tested the hypothesis that a high sense of personal mastery would prospectively predict stress reactivity. Measures of pain, perceived stress, fatigue, and mean arterial pressure (MAP) were collected before, during, and after two interpersonal stressors conducted on 73 individuals with RA. Factor analysis of the personal mastery scale yielded two independent factors: a 5-item “fatalism” component and a 2-item “control” component. Individuals with high fatalism scores reported overall greater joint pain at baseline and those scoring high on control exhibited lower MAP, and reported less stress and fatigue at baseline. After controlling for baseline differences, those high in control exhibited greater MAP increase during stress, and less drop in pain when compared to those low in control. These results suggest that individuals high in control may be more susceptible to the effects of acute stress; however, the overall beneficial aspects of high control outweigh the acute negative effects. Personal mastery may play a role in the experience of pain, stress, and fatigue for people with RA.  相似文献

Objective: This study tested whether social cognitions from the reasoned action approach (RAA) can be reliably measured in a sample of primary school children (aged 4–6 years) and whether these RAA measures are predictive of physical activity.

Design: Longitudinal observational study with repeated measures over six months.

Measures: RAA variables were measured using a novel choice paradigm between physically active and sedentary pastimes. Relative reinforcing value, covariates (sex, age, deprivation and BMI) and physical activity by accelerometry (primary outcome) were also measured.

Results: RAA cognitions could be measured with acceptable retest reliability and discriminant validity and social norms regarding parents and teachers (but not friends) were correlated with physical activity and change in physical activity when relative reinforcing value and other covariates were controlled for.

Conclusions: RAA cognitions can be reliably measured in primary school children aged 4–6 and RRA measures appear useful in understanding children’s activity choices and may potentially inform future interventions.  相似文献

Abstract

The fear of dental treatment in adults can be characterised in several ways, loosely related, such as anticipating being afraid, avoiding dental check-ups and seeking treatment only under general anaesthesia. Defined thus, at least a quarter of adults are highly afraid of dentistry. The feared experiences are many, including most frequently, pain. Several studies have shown that anxious patients experience less pain during treatment than they expect. It remains to be confirmed that these are typical experiences because other studies show that local anaesthesia can fail to protect patients from sudden pain in 13% of treatments on average. Expectations of pain are highly resistant to change, the result probably of several influences including distortion in recall of pain-free treatment, intermittent experience of sudden severe pain, expecting pain in order to reduce its impact, and uncertainty about treatment. It has yet to be shown that experience free of discomfort can reduce these expectations. However, relaxation instructions and information about pain management and stop signals can reduce pre-treatment fear. To prevent the onset and the maintenance of anxiety: the prevention of pain is essential; controlled behavioural studies of the treatment of pain and other experiences such as panics are needed. Finally, the need for new instruments to assess all aspects of fear of dentistry is described.  相似文献

BackgroundThe English Improving Access to Psychological Therapies (IAPT) initiative aims to make evidence-based psychological therapies for depression and anxiety disorder more widely available in the National Health Service (NHS). 32 IAPT services based on a stepped care model were established in the first year of the programme. We report on the reliable recovery rates achieved by patients treated in the services and identify predictors of recovery at patient level, service level, and as a function of compliance with National Institute of Health and Care Excellence (NICE) Treatment Guidelines.MethodData from 19,395 patients who were clinical cases at intake, attended at least two sessions, had at least two outcomes scores and had completed their treatment during the period were analysed. Outcome was assessed with the patient health questionnaire depression scale (PHQ-9) and the anxiety scale (GAD-7).ResultsData completeness was high for a routine cohort study. Over 91% of treated patients had paired (pre-post) outcome scores. Overall, 40.3% of patients were reliably recovered at post-treatment, 63.7% showed reliable improvement and 6.6% showed reliable deterioration. Most patients received treatments that were recommended by NICE. When a treatment not recommended by NICE was provided, recovery rates were reduced. Service characteristics that predicted higher reliable recovery rates were: high average number of therapy sessions; higher step-up rates among individuals who started with low intensity treatment; larger services; and a larger proportion of experienced staff.ConclusionsCompliance with the IAPT clinical model is associated with enhanced rates of reliable recovery.  相似文献

This study investigated the role of individual resources, notably self-efficacy, gratitude, and hope, in subjective well-being of white dormitory students at a historically white institution of higher learning. Using a convenience sample of white students (N?=?227), we tested the role of generalised self-efficacy, gratitude, and hope as indicators of a latent factor, labelled personal resources, in a structural equation model with subjective well-being as the latent output variable, measured by self-esteem and satisfaction with life. Path analyses indicated a reasonable fit between the data and our hypothesised theoretical model which proposed positive relations between levels of generalised self-efficacy, gratitude, dispositional hope, self-esteem and satisfaction with life. White students were psychologically doing well, considering above-midpoint levels obtained for levels of generalised self-efficacy, gratitude, dispositional hope, and satisfaction with life However, scores obtained for self-esteem and adult dispositional hope were below the mid-point and neutral respectively, indicating that White students do not agree that they experience high levels of these two psychological strengths. White female students experienced higher levels of hope, gratitude, and life satisfaction, while no significant gender differences were found for generalised self-efficacy and self-esteem. The results of this study highlight the potential for using psychological strengths to promote well-being in racially diverse students.  相似文献

This paper was given as the Annual Ellen Noonan Counselling Lecture on July 2012 and retains some of the spoken style of the lecture. It uses examples of Ellen Noonan’s work to examine aspects of the process of teaching and learning psychodynamic practice. The difficulties of how to embed theoretical knowledge with its clinical application are discussed and the question of what are the key skills of the self-reflective practitioner is raised with reference to whether, and how, they can be taught or learnt. It is suggested that part of this process consists in helping students, and their teachers, to be more comfortable with not knowing, a concept that is both counter intuitive and counter cultural. From this aspects of contemporary therapeutic practice, with specific reference to psychodynamic short-term therapy, are addressed. The paper looks at the ambivalence felt by many psychodynamic clinicians towards working within a short-term paradigm in current workplace settings and how this might be addressed. The paper discusses the intrinsic qualities of a psychodynamic short-term approach and its relation to contemporary therapeutic modalities. It is suggested that the increasing managerial culture, leading to the ascendance of protocol driven, manualised and structured therapies, represents an attack on the relational and must be challenged.  相似文献

Assessing facial symmetry is an evolutionarily important process, which suggests that individual differences in this ability should exist. As existing data are inconclusive, the current study explored whether a group trained in facial symmetry assessment, orthodontists, possessed enhanced abilities. Symmetry assessment was measured using face and nonface stimuli among orthodontic residents and two control groups: university participants with no symmetry training and airport security luggage screeners, a group previously shown to possess expert visual search skills unrelated to facial symmetry. Orthodontic residents were more accurate at assessing symmetry in both upright and inverted faces compared to both control groups, but not for nonface stimuli. These differences are not likely due to motivational biases or a speed–accuracy tradeoff—orthodontic residents were slower than the university participants but not the security screeners. Understanding such individual differences in facial symmetry assessment may inform the perception of facial attractiveness.  相似文献
