Reliability of parental reports using the Katz Adjustment Scales: before and after hospital admission for schizophrenia

We examined the interrater and test-retest reliability of the KATZ Adjustment Scale (Relative rated or R form) longitudinally in a sample of schizophrenic patients, assessing their function before hospital admission, as well as at 1 and 9 mo. after discharge. Changes in mean scores over those assessments suggested sensitivity to change while mothers and fathers both completed the measure with moderate consistency over time. Interrater reliability was moderate at best and quite poor at initial testing, when the subjects were most disturbed clinically, suggesting that the scales may be acceptable when the individual is stable but that ratings may be unreliable when there is an exacerbation in clinical state.     

The impact of drug screening on selection decisions

This paper discusses the use of drug screening for employee selection decisions. Common methods of drug screening are described, and a recent study of drug screening accuracy is summarized. It is argued that drug screening is subject to the same standards as are other selection procedures, and that human resource professionals must assume responsibility for understanding the potential problems associated with drug screening. Issues relevant to determining the benefits of drug screening are discussed, and an illustration of the impact of drug screening on decision accuracy is presented. It is suggested that, in many instances, the value of drug screening in the selection process may be low enough to warrant serious concern. Implications for human resource research and practice are noted.An earlier version of this paper was presented at the 95th Annual Convention of the American Psychological Association in New York; August 31, 1987.

Perceptual and conceptual variants of the oddity task as a predictor of learning disability

This paper compares LD and non-LD peers on eight variants of the oddity task. This study is part of a larger programmatic research effort aimed at the development of a screening test to detect preschool children who currently pass existing screening tests but, nonetheless, subsequently experience school failure. The theoretical orientation of this approach is to assess active, ongoing cognitive processing ability. The oddity task, which can be structured to assess such processing ability, was evaluated in the present study as a potential component of this screening test. Consistent with a priori predictions, the data resulted in strong group and developmental differences. Oddity performance increased over age, with the non-LD children performing consistently better than their LD peers at each age. Perceptual and conceptual factors were manipulated across the oddity variations, and both factors contributed to group differences. These results were discussed in relationship to early diagnosis and prognosis for learning disabilities that might result from deficiencies in abstract processing ability.The authors would like to express their thanks to the schools, teachers, and students who participated in this study.

An evaluation of the family adaptability and cohesion evaluation scales and the circumplex model

Two basic assumptions of the Circumplex Model of family systems were evaluated: (1) Healthy families evidence balanced degrees of cohesion and adaptability, whereas problem families evidence extreme degrees, and (2) families with balanced degrees of cohesion and adaptability possess more positive communication skills than families with extreme degrees. Subjects were 58 mother-son dyads from father-absent families. In 29 of the families the adolescent was a juvenile offender, while in the remaining families there was no history of arrest or psychiatric referral. The dyads completed the Family Adaptability and Cohesion Scales (FACES) and an unrevealed differences interaction task. FACES was highly proficient at differentiating delinquent from nondelinquent families. Moreover, in families with balanced degrees of cohesion and adaptability, the mothers' communication was significantly more supportive and explicit, and the dyads evidenced significantly greater warmth and affection than dyads with extreme degrees.This research was supported by funding to the Department of Psychology at Memphis State University granted through the Centers of Excellence Program of the State of Tennessee.

Susceptibility to prosocial and antisocial influence in adolescence following mindfulness training

Mindfulness training programmes have shown to encourage prosocial behaviours and reduce antisocial tendencies in adolescents. However, less is known about whether training affects susceptibility to prosocial and antisocial influence. The current study investigated the effect of mindfulness training (compared with an active control) on self-reported prosocial and antisocial tendencies and susceptibility to prosocial and antisocial influence. 465 adolescents aged 11–16 years were randomly allocated to one of two training programmes. Pre- and post-training, participants completed a social influence task. Self-reported likelihood of engaging in prosocial and antisocial behaviours did not change post-training, and regardless of training group, participants showed a higher propensity for prosocial influence than for antisocial influence. Finally, participants were less influenced by antisocial ratings following both training programmes.     

Negative priming insame-different matching: Further evidence for a central locus of inhibition

Responses to recently ignored information may be slower or less accurate than responses to information not recently encountered. Such negative priming effects imply that the mechanism of selective attention operates on unattended, as well as attended, information. In the present experiment, subjects judged the second and fourth letters of five-letter strings (e.g., BABAB) as “same” or “different.” Responses were slower when a target letter was identical to the distractors presented in the immediately preceding trial. This effect did not depend on which response was required on the current or preceding trial. The results suggest that ignored information is functionally disconnected from the response system as a whole, rather than from a specific response.
