Locus of Control and Hostility: Sex Differences

The Nowicki-Strickland Internal-External locus of control scale and the Hostility and Direction of Hostility Questionnaire were administered to 35 male and 35 female college students. In both the total sample and the female sample, significant correlations were observed between locus of control and hostility with an external locus of control being associated with greater hostility. Although locus of control was significantly related to all of the hostility scores in the female sample, the male sample generally showed no significant relationship between locus of control and hostility. The sex differences in the data and the possibility of item overlap between the locus of control and hostility measures are discussed.     

New evidence on the reliability and validity of the pediatric oncology quality of life scale

Abstract

The present paper replicates and extends previous studies on the psychometric properties of the Pediatric Oncology Quality of Life Scale (POQOLS). The research questions were focused on (a) internal consistency; (b) relation with demographics; and (c) ability to discriminate between patient groups. Data were gathered in a Dutch-speaking Belgian sample of 73 pediatric oncology patients, drawn from the population of a university hospital. The parents completed the POQOLS, a 21-item parent-report inventory for the assessment of physical restriction, emotional distress and discomfort from medical treatment in pediatric oncology patients. The results support the psychometric quality of the POQOLS. Three of the core aspects of quality of life are tapped using sufficiently short and internally consistent subscales. The instrument is free from relations with demographics and shows good discriminant ability to differentiate between patient groups according to time since diagnosis, treatment status and diagnosis.     

Assessing reinforcers under progressive schedule requirements.

Recent research findings suggest that reinforcing stimuli may be differentially effective as response requirements increase. We extended this line of research by evaluating responding under increasing schedule requirements via progressive‐ratio schedules and behavioral economic analyses. The differential effectiveness of preferred stimuli in treating destructive behavior maintained by automatic reinforcement also was examined. Results showed that one of two stimuli was associated with more responding under increasing schedule requirements for the 4 participants. Furthermore, stimuli associated with more responding under increasing schedule requirements generally were more effective in treating destructive behavior than stimuli associated with less responding. These data suggest that progressive‐ratio schedules and behavioral economic analyses may be useful for developing a new technology for reinforcer identification. From a clinical perspective, these results suggest that two reinforcers may be similarly effective for low‐effort tasks and differentially effective for high‐effort tasks.     

Functional analysis and treatment of self-injury associated with transitions.

We applied functional analysis methodology to the assessment and treatment of 2 individuals' self‐injurious behavior (SIB), which was reported to be occasioned by transitions from one activity or location to another. A structural (task) analysis of activity transitions identified at least three separate components that might influence behavior either alone or in combination: (a) termination of a prechange activity, (b) initiation of a postchange activity, and (c) movement from one location to another. Results of preference and avoidance assessments were used to identify activities to which participants were exposed in varying arrangements during transitions in a functional analysis. Results of 1 participant's functional analysis indicated that his SIB was maintained by avoidance of having to change locations, regardless of the activity terminated prior to the change or the activity initiated following it. The 2nd participant's analysis revealed the same function but also an additional one: avoidance of certain task initiations. This information was used to identify transition contexts during intervention and to design treatment procedures appropriate for a given context and behavioral function. A procedure involving advance notice of an upcoming transition had no effect on SIB, and differential reinforcement of alternative behavior (DRA) had limited effects in the absence of extinction. Sustained decreases in SIB were observed when DRA was combined with extinction and response blocking. Further extensions of functional analysis methodology to the assessment of problem behavior in situations characterized by multiple or protracted stimulus changes are discussed.     

The Tromsø Social Intelligence Scale, a self-report measure of social intelligence

Social intelligence is a construct that not only appeals to laymen as a relevant individual difference but also has shown promising practical applications. Nevertheless, the use of social intelligence in research and applied settings has been limited by definitional problems, difficulties in empirically differentiating social intelligence from related constructs, and the complexity of most existing measures of social intelligence. The goal of the present research was to address some of these obstacles by designing a multi‐faceted social intelligence measure that is short and easy to administer. Three studies were conducted to develop and validate the Tromsø Social Intelligence Scale (TSIS). Study 1 examined professional psychologists’ interpretations of social intelligence to derive a consensually agreed‐upon definition of the construct. In Study 2, a large pool of social intelligence items were tested, and a 3‐factor, 21‐item scale was identified. In Study 3, the stability of this measure was confirmed.     

Primary Care and Clinical Psychology: Assessment Strategies in Medical Settings

There is ample evidence regarding medical-psychological comorbidity to consider clinical psychology as a viable component of health care services in medical settings. Psychologists can become valuable assets to primary care physicians who treat a high number of primary psychiatric cases as well as medical cases with secondary psychological symptoms. Psychologists who function in hospital-based clinics as well as affiliates with primary care (PC) offices can provide empirically supported assessment services that can make treatment more effective and efficient. Multiple studies indicate high prevalence rates of psychiatric patients in PC settings using various instruments. This paper reviews selected assessment tools that have established diagnostic validity and reliability that can be both strategic for patient care and useful to reinforce psychologist collaboration with primary care physicians (PCP).

Trait anxiety and trait anger measured by ecological momentary assessment and their correspondence with traditional trait questionnaires

Ecological momentary assessments (EMA) of anxiety and anger/hostility were obtained every 25–30 min over two 24-h periods, separated by a median of 6 months, from 165 employees at a university in the Northeast. We used a multilevel trait-state-error structural equation model to estimate: (1) the proportion of variance in EMA anxiety and anger/hostility attributable to stable trait-like individual differences; (2) the correspondence between these trait-like components of EMA anxiety and anger/hostility and traditional questionnaire measures of each construct; and (3) the test–retest correlation between two 24-h averages obtained several months apart. After adjustment for measurement error, more than half the total variance in EMA reports of anxiety and anger/hostility is attributable to stable trait-like individual differences; however, the trait-like component of each construct is only modestly correlated with questionnaire measures of that construct. The 6-month “test–retest” correlations of latent variables representing the true 24-h EMA average anxiety and average anger are quite high (r ? 0.83). This study represents the longest follow-up period over which EMA-based estimates of traits have been examined. The results suggest that although the trait component (individual differences) of EMA momentary ratings of anxiety and anger is larger than the state component, traditional self-report questionnaires of trait anxiety and anger correspond only weakly with EMA-defined traits.     

What cognitive abilities are involved in trail-making performance?

The cognitive abilities involved in the Connections (Salthouse, et al., 2000) version of the trail making test were investigated by administering the test, along with a battery of cognitive tests and tests of complex span and updating conceptualizations of working memory, to a sample of over 3600 adults. The results indicate that this variant of the trail making test largely reflects individual differences in speed and fluid cognitive abilities, with the relative contributions of the two abilities varying according to particular measure of performance considered (e.g., difference, ratio, or residual). Relations of age on trail making performance were also examined. Although strong age differences were evident in the Connections and working memory measures, with both sets of variables there was nearly complete overlap of the age differences with individual differences in speed and fluid cognitive abilities.     

Psychometric properties of the Situational Inventory of Body-Image Dysphoria-Short form in a Spanish sample

The primary objective of this study was to translate and validate Situational Inventory of Body-Image Dysphoria-Short form (SIBID-S) in a Spanish population. The scale consists of 20 items to assess the frequency of dysphoric body-image emotions in certain situational contexts, using a five-point rating scale. The questionnaire was administered to 214 women between the ages of 14 and 29 years, from primary and secondary schools and a university. Principal components analysis indicated a one-factor structure for the entire sample and both younger (<18) and older (≥18) participants. Internal consistency was high (0.94), and the test–retest reliability over 1 month ranged between 0.89 and 0.93. The SIBID-S showed good convergent validity in relation to other pertinent measures of body image, eating pathology, and self-esteem. Moreover, the SIBID-S was differentiated low-risk, subclinical eating disturbed, and clinical eating disordered patients. Results support the potential utility of the SIBID-S in the Spanish female population, including a younger group than previously studied, as well as its usefulness in the assessment of body image among females varying in degrees of eating pathology.
