The clinical vignette: Use in teaching and evaluation of group therapists

This paper describes the use of a written vignette as an aid in teaching group psychotherapy. Educators can determine in advance their expectations of the students' understanding of the vignette. Trainees evaluate the salient data, recognize patients' and therapist's contributions to the process, and conceptualize at three levels: intrapsychic, interpersonal and group-as-a-whole. This method supplements the usual training methods, and offers information about both the individual student and the entire class. This approach has an advantage of enabling educators to assess students in a relatively standardized fashion.     

The relationship between daily events and mood: The mood measure may matter

Measures of daily mood have been used as immediate indicators of the effects of the psychosocial environment, the latter concept often measured by daily events. We examined the prediction of two measures of daily mood, the Positive and Negative Affect Schedule (PANAS) and Nowlis Mood Adjective Checklist (MACL), by daily desirable and undesirable events and by day of the week. Unlike prior studies, the event assessment and type of subjects studied (community residents) were the same in both studies, allowing an attribution of differential associations between the two mood scales and either daily events or day of the week to the different mood measures. The mood measures had similar and expected associations with daily events, although the MACL scale generally had stronger associations with events. Surprisingly, the pattern of day of the week effects for positive, yet not negative, mood were different for the two mood measures. Consistent with the weekend's increase in desirable daily events, MACL positive affectincreased on weekends, relative to weekdays, whereas PANAS positive mooddecreased on weekends. Also, for both positive and negative affect scales, the MACL scales had stronger associations with day of week than the PANAS scales. These results suggest caution in the choice of mood measure to use in studies of daily events and pose questions about the meaning of these mood measures.This work was supported, in part, by grant MH39234 from NIMH.

The relationship between speed of information processing and cognitive ability

Speed of information processing as measured by various reaction time and inspection tasks has been shown to correlate with psychometric intelligence, and it has been suggested that general intelligence (g) is determined to some degree by the speed that information is processed. If this is so, then various measures of speed of information processing should correlate substantially with each other, and each should also correlate with a wide range of psychometric tests that load on g. Alternatively, intelligence may be considered to be a multi-faceted complex of partially related abilities with specific abilities being dependent upon specific cognitive processes. If this is the case, it should be possible to discover independent cognitive processes, some of which correlate with one facet or broad ability and some with another. This paper presents three experiments in which the relationship between intellectual ability and four speed of information processing measures was examined. These were rate of memory scanning, rate of retrieval of information from long term memory, speed of stimulus-response mapping and inspection time (IT). Results showed that correlations between IT and most reaction time measures of speed of information processing were low, and that correlations between different versions of IT were negligible. In addition, some cognitive tasks with verbal material (memory scanning rate for digits and Posner letter matching IT) correlated most substantially with Verbal Reasoning whereas non-verbal (two-line) IT consistently correlated with tests loading on g. It was thus suggested that while non-verbal IT may be a measure of a perceptual speed attribute that contributes to mental functioning, other “speed of information processing” parameters may be more specific to a subset of abilities.     

The development and validation of computer self-efficacy and outcome expectancy scales in a nonvolitional context

Computer self-efficacy and outcome expectancy scales were developed using 306 responses to a questionnaire distributed by a national mail survey to end users of computer systems in a variety of functional business areas. Confirmatory factor analysis using a structural equations approach was used to develop three scales. The scales were found to demonstrate satisfactory psychometric properties. The reliability coefficients for these scales were as follows: .85 for computer self-efficacy; .88 for work-related outcome expectancy; and .89 for personal outcome expectancy. The scales provide a strong foundation from which to refine the measurement of computer self-efficacy and outcome expectancy. From these refinements, empirical models that include self-efficacy and outcome expectancy as determinants of information technology acceptance at the individual level of analysis can be improved.     

Basic human values: The ethos for methodology

This paper draws on the personal experiences of part of a research project where the original methodology was flawed and needed to change to properly encompass the lives and experiences of the people who the research was for, namely users of mental health services living in supported housing. The change in methodology involved a recognition that the research could not be termed ‘value-free’; that researchers are not objective. It is argued that it was important to demonstrate that the information obtained in the research was ‘valid’, and that despite the subjective nature of the research, there are steps that can be taken to convince others that the information received is ‘real’. It is further argued that the traditional approach to research of separating theory (or knowledge) from practice was not only inappropriate in this sort of research, but is a false notion in any sort of action research that aims to promote change. The importance of the influence and power of service providers in action research is recognised, as well as the constraints placed on short-term funded projects. It was important for the methodology to be non-oppressive so that researchers adopted an open and honest approach and for researchers to become involved with the research participants. The implications of this ‘involvement’ are discussed. There is a concluding discussion about whether non-users of mental health services can be considered as allies in research. It is argued that all oppressed groups need their allies and if the research is led by basic human values, then working alongside people who depend on services can lead to emancipatory outcomes.     

An International Comparison of Personality Differences between Hospitality and Other Service Sector Managers

This paper seeks to examine the hypothesis that reliable and valid personality instruments could have international applicability. Utilising data from 327 practising managers drawn from service industries in the United Kingdom, Hungary and the Czech Republic, the research offers a basis for discriminating between the profiles of hospitality and other service sector managers employing stepwise discriminant function analysis, F-tests and classification ratios. The findings, based on a subsequent ANOVA, suggest that these personality profiles extend across the three countries under study. Also, the research provides a methodological approach for consideration in future meta-analytical studies of the processes of management development.     

BEHAVIORAL ASSESSMENT AND TREATMENT OF CHRONIC FOOD REFUSAL IN HANDICAPPED CHILDREN

In this study, we examined the eating behavior of four handicapped children, none of whom exhibited self-feeding skills. All children had a history of food refusal and were nutritionally at risk; one child received all nourishment by way of a gastrostomy tube. Baseline data taken during mealtimes indicated that all children accepted very little food, expelled food frequently, and engaged in a number of disruptive behaviors. Treatments consisted of one or more of the following contingent events: social praise, access to preferred foods, brief periods of toy play, and forced feeding. Results of multiple-baseline and reversal designs showed marked behavioral improvement for each child and increases in the amount of food consumed. Further improvements were noted at follow-up, which ranged from 7 to 30 months posttreatment.     

Soft tissue anatomy of the tongue and floor of the mouth: An ultrasound demonstration

Ultrasound technology has not been used extensively in the study of normal and abnormal oral physiology and speech. Features such as soft tissue detail, real-time motion display, and subject safety make ultrasound ideal for imaging the tongue and the floor of the mouth. This study demonstrates visualization of the muscles of the tongue and floor of the mouth for a normal subject using ultrasound imaging. By employing submandibular transducer placement of real-time sector scanners, tongue anatomy and motion were continuously visualized in sagittal or coronal planes. In addition to the entire tongue surface, much of the intrinsic anatomy was identified including: the genioglossus, geniohyoid, mylohyoid, and digastric muscles; fascial boundaries such as the median fibrous septum, floor intermuscular septum, and paramedian septums; and the hyoid bone. A tongue excised from a human cadaver was scanned using ultrasound and dissected to confirm the anatomy seen in the live tongue. Tongue surface shape and configuration of the intrinsic tissue structures were observed and compared for the phonemes /k/, /u/, and /i/. Anatomical landmarks in the resting and speaking tongue are discussed as well as applications in the fields of speech science and speech pathology.     

Is hostility linked with affiliation among males and with achievement among females? A critique of Pollak and Gilligan

This investigation attempted to replicate and to clarify methodologically an investigation by Pollak and Gilligan (1982). Those investigators reported sex differences in violence imagery to Thematic Apperception Test (TAT) pictures depicting affiliation and achievement situations. Pollak and Gilligan concluded that men perceive danger in situations of affiliation whereas women perceive danger in situations of achievement. It was demonstrated in the present study that Pollak and Gilligan incorrectly classified TAT cards into motivational categories, which may have resulted in incorrect inferences. In addition, their findings could not be replicated when using four different systems for classifying TAT cards into motivational categories. Other potential sources of error in their research, including a restrictive scoring scheme for hostility, unusual instructions, and failure to control for sex role in the TAT pictures, did not influence the pattern of results.
