VALIDITY GENERALIZATION RESULTS FOR LAW ENFORCEMENT OCCUPATIONS

The Schmidt-Hunter interactive validity generalization procedure was applied to validity data for cognitive abilities tests for law enforcement occupations. Both assumed artifact distributions, and distributions of artifacts constructed from information contained in the current sample of studies were used to test the hypothesis of situational specificity and to estimate validity generalizability. Results for studies using a criterion of performance in training programs showed that validities ranged from .41 to .71, and for four test types the hypothesis of situational specificity could be rejected using the 75% decision rule. For the remaining test types, validity was generalizable, based on 90% credibility values ranging from .37 to .71. Results for studies using a criterion of performance on the job indicated that the hypothesis of situational specificity was not tenable for three test types, which had validities between .17 and .31. For the remaining test types, estimated mean true validities ranged from .10 to .26 and were generalizable to a majority of situations. Results for both groups of studies were essentially identical for the two types of artifact distribution. Possible reasons for the apparently lower validities and lesser generalizability for job performance criteria are discussed, including possible low validity of the criterion (due to lack of opportunity by supervisors to observe behavior) and the potential role of noncognitive factors in the determination of law enforcement job success. Suggestions for specifically targeted additional research are made.     

PERFORMANCE APPRAISAL BEHAVIORS: SUPERVISOR PERCEPTIONS AND SUBORDINATE REACTIONS

This study examined supervisor perceptions and subordinate reactions to formal performance-appraisal reviews. The performance-appraisal behaviors of supervisors and the reactions of their subordinates were studied in a sample of university employees. A factor analysis revealed that there were three dimensions of formal performance appraisals: two developmental dimensions (being supportive; emphasizing performance improvement) and one administrative dimension (discussing pay and advancement). Regression analyses suggested that supervisors supported highly rated individuals and stressed improvement efforts for poor performers. After controlling for the level of previous performance ratings, results indicated that support in the appraisal review was associated with higher levels of employee motivation, while discussing pay and advancement was associated with higher levels of employee satisfaction. Unfortunately, improvement efforts by the supervisors did not influence job performance one year later.     

Study instrument for psychopathology in computer-assisted analysis of findings (Structured Psychopathologic Detection System)

With the Structured Psychopathological Evaluation-System (SPES) an instrument existed for employment of objective criteria. This study was designed to present an evaluation system based on new scientific results, that is applying on the strength of a reduced catalogue of symptoms (94 compared with 198 Items at SPES-A) to clinical routine. Additional findings differentiated by this system be able to classify by the help of an operational decision system.     

EEG findings as a principle of military medicine disability evaluation in conditions following craniocerebral injuries

295 expert opinans of the NVA (National People's Army) in conditions after craniocerebral traumas for which an EEG findings was present were subjected to an retrospective analysis to determine the importance of EEG for export opinion. In 59.3% of cases EEG was significant for expert opinion, but was of prime importance only in 1.3%. In 161 expert opinions the total damage of the body was determined. This gave the possibility of a statistical correlation of individual EEG findings with the extent of the body damage. Mean percentage values of the individual degrees of severity of EEG changes could be calculated on the basis of these data. The great importance of EEG for military medical opinion could also be confirmed in comparison with 8 other clinical data and findings.     

Some problems of genetic counseling in schizophrenic psychoses

The authors sum up the most important basic principles of diagnostics and genetics of the schizophrenic psychoses from the viewpoint of genetic counseling for the practising psychiatrist and medical geneticist. Regarding genetic counselling strategy, in addition to nosological considerations, they stress the importance of socio-cultural and social psychological factors and of the emotional atmosphere in the family, which should all be taken into account together. Because of the special situation of schizophrenic (and in general, psychiatric) patients and their families, they regard it as advisable to set up a separate psychiatric genetic counselling service.     

Arthur Kronfeld (1886-1941)--a psychiatrist in the service of psychotherapy

The psychotherapeutic life-work of psychiatrist Arthur Kronfeld has almost fallen into oblivion. Against the background of the 100th anniversary of his birth the author traces Kronfeld's psychotherapeutic career, pointing out his activity at the Berliner "Institute of Sexual Research" under Magnus Hirschfeld, and his psychotherapeutic concept--the psychagogic guidance of the patient--and its connection with the individual psychology of Alfred Adler. Kronfeld translated his theoretical positions into activities directed towards socialization and the teachability of psychotherapy which are still worthy of note by those engaged in the field.     

Ulnar sulcus syndrome--a contribution to course and prognosis

Of 1028 patients with 1138 peripheral nerve lesions, 142 suffered from an electrophysiologically proven SUS. At follow-up, 93 patients could be restudied. Spontaneous regressions were observed in patients below the age of 40 years and in case of a history under 6 months. So-called late pareses receded in no case without operative displacement of the ulnar nerve. However, if the etiology is unknown, the present results of investigation require reserve towards operative therapy.     

Stomatologic studies in schizophrenic patients--contributions to the problem of medical and social integration of psychiatric patients

Stomatological examination was carried out on 173 patients with schizophrenia (IKK-Nr. 295). It was observed that this group of patients showed a diminished dental and oral care in comparison to the average population of the same region. The close cooperation of dentists with the institutions for chronic patients will be as prophylactic measure in favour of the patients encouraged.     

Results of neurophysiologic studies in ophthalmic migraine

The influence in 8 of our patients with ophthalmic migraine of photic driving with sine-like flashing lights on EEG background activity was checked and the visually evoked potentials following the application of diffused simple light stimuli were analyzed using the recovery cycle technique. The results indicate a slightly increased tonic activity of the structures of the mesencephalic formatio reticularis, such as may be produced by slight functional disturbances. Some vegetative secondary symptoms of migraine attacks and some of the changes in EEG observed in patients with ophthalmic migraine are explicable by such an abnormality.
