Locus of Control Orientation Among Obese Adults in Outpatient Treatment for Obesity

We studied locus of control (LOC) in samples of obese and nonobese subjects. We administered Rotter's (1966) I-E Scale to 106 obese adults in outpatient treatment for obesity and to 99 nonobese controls. The obese subjects were significantly more internally oriented than the control group. These findings challenge currently held assumptions on the directionality of LOC in obese groups. The results contradict the consensus among researchers that obese individuals have an external LOC orientation. The finding that internal LOC is associated with the obese condition may be a useful predictor variable influencing obesity treatment, approaches, and outcome.     

Development of a measure of symptoms in chronic fatigue syndrome: The profile of fatigue-related symptoms(pfrs)

Abstract

Chronic fatigue syndrome (CFS) is a disorder of uncertain aetiology which attracts increasing research interest. This paper describes the development of a multidimensional measure incorporating the diverse symptoms associated with the illness. The Profile of Fatigue-Related Symptoms (PFRS) has four scales: emotional distress, cognitive difficulty, fatigue and somatic symptoms. These showed good convergence with comparison measures, high reliability and high internal consistency. CFS patients had markedly elevated scores compared with a student comparison group, and these scores correlated with indices of illness severity. The PFRS is a short and easily administered measure which, it is suggested, may be used to assess patients in terms of the severity and pattern of their disorder, to relate subjective symptoms to immunological and other findings, to evaluate the effects of treatments, and to compare the symptomatology of CFS with that in other fatiguing illnesses.     

Memory instructions, vocalization, mock crimes, and concealed information tests with a polygraph

Accuracy rates with polygraphs using concealed information tests (CITs) depend on memory for crime details. Some participants read instructions on murdering a dummy victim that specified exact crime details asked on the subsequent CIT. Others read instructions not stating details, but still requiring interaction with the exact same details for the crime. For example, the murder weapon was under four heavy boxes. Instructions stated either "... remove the 4 boxes ..." or "... remove the boxes ..." Thus, each group removed four boxes, but only one group was primed with the number "4" beforehand. In addition, the victim unexpectedly shouted at some participants during the crime. An innocent group was not exposed to either manipulation. Memory, detection scores, and detection rates were lower for guilty participants not primed with details. Sound affected detection scores but not memory, and there was no interaction between the two factors. Information tests are limited by how crime information is received.     

Assessing within-person personality variability via frequency estimation: More evidence for a new measurement approach

Variability in personality has been recognized in recent years as an important aspect of personality both conceptually and empirically. A relatively new and efficient method of obtaining variability information is frequency-based personality assessment (Edwards & Woehr, 2007). The purpose of the present research is to further examine the viability of frequency-based personality measurement as an alternative to traditional (Likert-type) measurement and to assess the usefulness of the variance-based parameters. Toward this end, three studies are presented. Specifically, Study 1 examined relationships between a frequency-based measure of the Big Five personality traits and several motivational variables. Study 2 examined the moderating role of temporal consistency information (provided by frequency-based measurement) on relationships between personality and peer ratings of task performance. Study 3 compared the frequency-based measure to a Likert-type measure with respect to each measure’s susceptibility to deliberate response distortion. Results indicated that consistency information increases the predictive validity of agreeableness and conscientiousness and that a frequency-based format is less susceptible to faking than a Likert-type format for conscientiousness, emotional stability, and openness to experience.     

Serial murderers' spatial decisions: factors that influence crime location choice

The outcome of German serial murderer spatial decision making was measured as the straight‐line distance (km) between murderer home locations and each crime location (i.e. body recovery location). Geographic and series development data, as well as information on age, intelligence, motive, marital status, employment status, and mode of transportation of 53 German serial murderers was collected from police and prosecution service files and judicial verdict records. Potential effects of the aforementioned factors on spatial decisions were assessed. Results showed that 63% of the murderers lived within 10 km of their crime locations. Home‐to‐crime distance was negatively correlated with murderer age and positively correlated with murderer IQ score. Results also showed that the mode of transportation used by murderers had an effect on their spatial decisions. Results are discussed in terms of understanding serial murderer spatial decision‐making and implications for police investigations. Copyright © 2005 John Wiley & Sons, Ltd.
