General and Specific Cognitive and Psychomotor Abilities in Personnel Selection: The Prediction of Training and Job Performance

Use of ability tests in personnel selection is addressed beginning with methodological issues. Studies are reviewed that show that almost all the validity of cognitive tests comes from general cognitive ability, g. Psychomotor ability is reviewed and found to have both higher- and lower-order factors, contrary to long-held beliefs. It was found that the higher-order general psychomotor factor was one source of validity of psychomotor tests. Additionally, psychomotor tests were shown to contain measures of g and to increment the validity of g-based measures very little.     

Communicating Negative Hire Decisions to Applicants: Fulfilling Psychological Contracts

This study demonstrates that characteristics of rejection letters combine in a complex manner to affect impressions of the organization, and likelihood of re-applying to and of patronizing the organization. Specifically, the most negative reactions to rejection letters were found when a contact person existed, along with a long time interval before receiving a letter that failed to include an explicit statement of rejection. Some support was found for the failure to receive a rejection letter as a psychological contract violation.     

Symbolic Representation by Pigeons

The capacity for symbolic representation is a prerequisite for the development of human language because words, the basic units of language, are symbols that represent things. But symbolic representation may also serve a nonlinguistic role of organizing events into categories having the same meaning, and such a capacity could have considerable survival value for many species. In a number of experiments, my co-workers and I have found that pigeons that are trained to treat two different stimuli similarly also learn that those stimuli are commonly represented and, thus, that they have the same meaning. We have demonstrated evidence for such common representations in a number of ways, but perhaps the most convincing is when pigeons learn a new association involving one of the presumed commonly represented stimuli, and without further training demonstrate that they have learned a similar association involving the other stimulus. Furthermore, we have found that when pigeons are trained to treat two stimuli similarly, one of those stimuli is represented in terms of the other. These results have implications not only for the generality of cognitive processes across species, but also for the generality of symbolic representation beyond language use.     

A comparison of self-report and interview diagnoses of DSM-III-R personality disorders

A total of 73 psychiatric inpatients, all of whom (but two) fulfilled criteria for at least one specific personality disorder (PD) on SCID-II PQ, were interviewed with the help of PDE. The self-report PD diagnosis was confirmed in 35 (48 per cent) patients. The diagnostic agreement between the two instruments was poor, yielding an overall weighted kappa of 0.22. Levelling off the PD base rates by increasing or decreasing the diagnostic threshold of SCID-II PQ and PDE respectively increased the overall weighted kappa to 0.38 in both instances. 70 per cent of SCID-II PQ but only 29 per cent of PDE personality disorders were of extensive type. Most frequent important co-occurrences occurred between individual PD types within cluster 2. On the whole, the results confirmed the relatively poor agreement between self-report and interview PD diagnoses. The utilization of self-report questionnaires in a clinical practice remains a controversial issue. © 1998 John Wiley & Sons, Ltd.     

A comparison of noncontingent reinforcement,other competing stimulation,and liquid rescheduling for the treatment of rumination

Modified versions of three popular nonaversive treatments for rumination in a person with profound developmental delay were evaluated using an alternating treatments design (ATD) as a component of an ABAB design. Results showed that the most effective intervention involved noncontingent feeding every 20 s for the 30 min immediately following a meal. Further analysis demonstrated that no significant increase in rumination occurred during the 60 min after the treatment procedure had expired, thus indicating that rumination was not merely postponed. Results are discussed in terms of their relation to currently popular (satiation) interventions for the treatment of rumination in individuals with developmental disability. Future research needs are proposed from an analysis of known behavioral and physiological variables and their possible interactions. ©1997 by John Wiley & Sons, Ltd.     

Patient-Informed Treatment Development of Behavioral Smoking Cessation for People With Schizophrenia

The objective of this study was to use qualitative methodology to tailor and refine an existing smoking cessation intervention for the population of people who use cigarettes and are diagnosed with schizophrenia, schizoaffective, or psychotic disorder. Successive cohort design methodology was used to iteratively modify the treatment in response to qualitative participant, therapist, and consultant feedback on the intervention. Qualitative methodology for participant feedback included analysis of semistructured interviews with participants, visualization of app utilization data, and stakeholder feedback from study therapists and consultants. Using the successive cohort design, a tailored multicomponent mobile health smoking cessation intervention was developed. The intervention included mobile contingency management (i.e., financial compensation for confirmed abstinence from smoking), pharmacotherapy for smoking cessation, cognitive-behavioral counseling sessions, and the Stay Quit app for relapse prevention. Two cohorts (N = 13) were completed in the study; after each cohort, the treatment protocol was revised. The intervention is described, as well as the qualitative findings from each cohort and subsequent changes made to the intervention based upon patient and provider feedback. Metrics of patient engagement included treatment adherence (40% in Cohort 1 and 63% in Cohort 2). Both participants and therapists reported that the intervention was helpful. Over one third of participants self-reported abstinence at posttreatment. Since qualitative methodology is often underutilized in mental health treatment development, this study demonstrates the utility of the successive cohort design for treatment development of behavior change interventions for at-risk, vulnerable populations.
