Continuing Medical Education: A Cross Sectional Study on a Developing Country’s Perspective

To determine the attitude of general practitioners towards continuing medical education (CME) and reasons motivating or hindering them from attending CME procedures, we conducted a cross-sectional survey from November 2013 to April 2014 in Karachi. Three hundred general practitioners who possessed a medical license for practice in Pakistan filled a pre-designed questionnaire consisting of questions pertaining to attitudes towards CME. Data was entered and analyzed using SPSS v16.0. 70.3% (n = 211) of the participants were males. Mean age was 47.75 ± 9.47 years. Only 67.33% knew about CME and only 52% had attended a CME session. Reasons for attending CME procedures reported were: need for updating knowledge, skills and competencies (67.30%), opportunity to meet colleagues (18.58%) and presenting scientific papers (8.97%). Mean Likert score was 1.67 (±0.667) for those who thought CME is worthwhile and 1.44 (±0.686) for those who consider their clinical duties as the major hurdle in attending CME procedures. Most common cause for not attending CME was lack of knowledge (32.66%) followed by time constraint (24%). Most physicians were not sufficiently informed about the potential benefits of CME and had never attended a CME session. Most common reason for attending CME procedures reported was need for updating knowledge, skills and competencies while reasons hindering physicians from attending CME were lack of knowledge and time constraint.     

Children show limited movement repertoire when learning a novel motor skill

Examining age differences in motor learning using real‐world tasks is often problematic due to task novelty and biomechanical confounds. Here, we investigated how children and adults acquire a novel motor skill in a virtual environment. Participants of three different age groups (9‐year‐olds, 12‐year‐olds, and adults) learned to use their upper body movements to control a cursor on a computer screen. Results showed that 9‐year‐old and 12‐year‐old children showed poorer ability to control the cursor at the end of practice. Critically, when we investigated the movement coordination, we found that the lower task performance of children was associated with limited exploration of their movement repertoire. These results reveal the critical role of motor exploration in understanding developmental differences in motor learning.     

Examining the role of two aspects of eWOM in online repurchase intention: An integrated trust–loyalty perspective

As electronic word‐of‐mouth (eWOM) has become an influential information resource for digital consumers who purchase products, understanding how the 2 ways of eWOM influence consumers' online repurchase intention (ORPI) becomes very pivotal. Despite its importance, there is no study in the literature that examined receiving and participating aspects of eWOM in an integrated perspective. The purpose of this study is to understand how 2 controversial eWOM aspects influence ORPI of consumers. Moreover, this study examines the mediating roles of e‐trust and e‐loyalty in the association between 2 sides of eWOM aspects and ORPI. The results indicated that 2 eWOM receiving factors, eWOM quality and eWOM quantity, have positive influences on e‐trust and ORPI. However, as an eWOM participating factor, the eWOM content has no significant influence on ORPI whereas another participating factor, the eWOM intensity, has the greatest impact on ORPI. Furthermore, the findings illustrate that e‐trust has a complementary mediation effect in the association between 2 receiving eWOM aspects and ORPI; likewise, e‐loyalty has a complementary mediation in the relationship between 2 participating eWOM aspects and ORPI.     

The impact of a laryngectomy on the spouse: Who is better off?

Background: Diabetes self-care is a key element in the overall management of diabetes. However, the importance of psychosocial factors for successful disease management is under investigated. This study aimed at exploring the role of coping styles and social support in the relationship between self-care activities and glycated haemoglobin in patients with type 2 diabetes.

Methods: One hundred adults (60% female, aged 40–70 years) with type 2 diabetes completed questionnaires assessing self-care activities, coping styles and social support. In addition, a blood test was performed to obtain glycated haemoglobin levels.

Results: Result showed significant relationships of glycated haemoglobin with self-care activities, coping styles and social support. Regression analysis indicated that social support had a moderating role on the relationship between self-care activities and glycated haemoglobin, such that, at very high levels of social support the association, between Self-Care and HbA1c disappears.

Conclusions: Findings indicate that health care providers, within the context of the Iranian social and cultural situation, should pay more attention to psychosocial factors when addressing self-care activities. Delineation of the role of coping styles and social support might be useful for identifying patients in need of particular counselling and support for improving self-care activities and HbA1c levels.     

Latent Structure of the Wisconsin Card Sorting Test after Pediatric Traumatic Head Injury

The performance of 80 pediatric patients with traumatic head injury (THI) on the Wisconsin Card Sorting Test (WCST; Heaton, Chelune, Talley, Kay, & Curtiss, 1993) was examined to determine the underlying latent structure. Exploratory factor analysis with oblique rotation identified three factors: response accuracy, failure to self-monitor, and learning. The response accuracy factor was directly affected by both age and length of coma. Level of performance on this factor also covaried with post-injury psychometric intelligence. It is concluded that interpretation of the WCST results of children with THI should consider the multifactorial nature of the instrument in combination with injury severity characteristics and demographic variables.     

Adaptive criterion setting in perceptual decision making

Pigeons responded in a perceptual categorization task with six different stimuli (shades of gray), three of which were to be classified as "light" or "dark", respectively. Reinforcement probability for correct responses was varied from 0.2 to 0.6 across blocks of sessions and was unequal for correct light and dark responses. Introduction of a new reinforcement contingency resulted in a biphasic process of adjustment: First, choices were strongly biased towards the favored alternative, which was followed by a shift of preference back towards unbiased choice allocation. The data are well described by a signal detection model in which adjustment to a change in reinforcement contingency is modeled as the change of a criterion along a decision axis with fixed stimulus distributions. Moreover, the model shows that pigeons, after an initial overadjustment, distribute their responses almost optimally, although the overall benefit from doing so is extremely small. The strong and swift effect of minute changes in overall reinforcement probability precludes a choice strategy directly maximizing expected value, contrary to the assumption of signal detection theory. Instead, the rapid adjustments observed can be explained by a model in which reinforcement probabilities for each action, contingent on perceived stimulus intensity, determine choice allocation.     

Neither backward masking of T2 nor task switching is necessary for the attentional blink

Identification of the second of two targets (T1, T2, inserted in a stream of distractors) is impaired when presented within 500 ms after the first (attentional blink, AB). Barring a T1-T2 task-switch, it is thought that T2 must be backward-masked to obtain an AB (Giesbrecht &; Di Lollo, Journal of Experimental Psychology: Human Perception and Performance, 24, 1454-1466, 1998). We tested the hypothesis that Giesbrecht &; Di Lollo's findings were vitiated by ceiling constraints arising from either response scale (experiment 1) or data limitations (experiment 2). In experiment 1, digit-distractors were replaced with pseudoletters to increase task difficulty, bringing performance below ceiling. An AB occurred without backward masking of T2. In experiment 2, a ceiling-free procedure estimated the number of noise dots needed for 80% T2 identification. An AB was revealed: fewer noise dots were required during the AB period than outside it. Both outcomes confirm that an AB can be obtained without either masking of T2 or task switching.     

Reliability and preliminary evidence of validity of a Farsi version of the depression anxiety stress scales

The internal consistency, test-retest reliability, and construct validity of the Farsi version of the Depression Anxiety Stress Scales were examined, with a sample of 306 undergraduate students (123 men, 183 women) ranging from 18 to 51 years of age (M age = 25.4, SD = 6.1). Participants completed the Satisfaction with Life Scale, Rosenberg Self-esteem Scale, and the Depression Anxiety Stress Scales. The findings confirmed the preliminary reliabilities and preliminary construct validity of the Farsi translation of the Depression Anxiety Stress Scales.     

What Are the Main Differences Between Behavioral and Systems Therapy with Couples? A Critical Account

This paper describes the main differences between behavioral and systems therapy with couples. To improve clinical decision making for a given case, the theoretical assumptions of the chosen treatment approach need to be clearly understood. Contrasting the two approaches will assist couple therapists in providing clinical services that better reflect the chosen theoretical framework. This paper reviews the common elements that can be found across models. A case example is presented to demonstrate the use of the therapy's theories and techniques.
